Topik yang akan saya bahas pada "Tugas Tantangan Masa Depan" ini adalah berkaitan tentang dampak dari teknologi. Saya seringkali mengobservasi dan mengamati dampak dari teknologi di lingkungan sekitar saya. Salah satu dampak dari teknologi yang paling dekat dengan masyarakat di sekitar saya adalah handphone. Handphone yang semakin pintar kini semakin mudah dimiliki oleh masyarakat di lingkungan sekitar saya dan seringkali saya melihat dengan mata telanjang keadaan anak-anak di lingkungan sekitar saya yang sudah sangat pandai menggunakan handphone. Tak jarang saya menemu sekumpulan anak yang bermain bersama menggunakan handphone mereka di tempat-tempat tertentu seperti pos satpam, dan tempat semacamnya. Di satu sisi, kemahiran anak-anak ini dalam mengoperasikan handphone menunjukkan bahwa generasi muda di lingkungan sekitar saya sudah tidak gagap teknologi dan justru telah berbaur dengan teknologi itu sendiri. Dampak dari teknologi ini telah merambat ke generasi muda lingkungan sekitar saya. Akan tetapi, di samping realita yang baik mengenai dampak dari teknologi tadi, ada realita buruk yang harus dihadapi pula. Tak jarang anak-anak ini mengabaikan sosialisasi dan lebih terbawa ke dalam tensi permainan yang mereka mainkan. Di samping itu, intensitas permainan mereka pun seringkali melebihi batas wajar dan bisa berjam-jam. Seringkali saya mengamati mereka masih bermain hingga malam hari. Tindakan ini sering dinamai mabar dan biasanya dilakukan oleh lebih dari 2 orang.

Melihat keadaan ini, saya menjadi terpikirkan akan suatu tantangan masa depan. Saya menjadi khawatir akan munculnya generasi muda yang melek teknologi, namun apatis di realita. Di satu sisi, saya memang cukup senang akan kemajuan generasi muda ini untuk adaptif terhadap teknologi, tapi di sisi lain saya prihatin dan cukup khawatir akan keadaan yang mungkin terjadi di masa yang akan datang. 

Isu ini menjadi penting dan cukup urgent karena memang tidak tampak sebagai suatu isu yang signifikan, namun jika terus terjadi bisa berdampak yang cukup berbahaya. Teknologi yang kita terima seharusnya bisa membantu kita menjadi lebih baik dan bukannya merusak kepribadian kita yang sebelumnya telah baik. Saya selalu memandang teknologi sebagai sesuatu yang memudahkan manusia dalam pekerjaannya dan saya selalu percaya bahwa teknologi memiliki dampak yang buruk jika tidak di-filter dengan baik oleh orang yang terpapar olehnya.

Sebagai mahasiswa, saya memiliki peran untuk menyadarkan masyarakat di lingkungan sekitar saya akan isu ini. Terkadang saya menegur anak-anak ini dan menyuruh mereka untuk kembali melakukan pekerjaan lain, seperti belajar, bermain permainan tradisional, ataupun membantu orang tua mereka. Pendekatan yang saya lakukan selalu dengan sopan dan santun, serta tidak pernah secara memaksa. Sebagai mahasiswa pun, saya harus beradaptasi terhadap hal ini. Menyadari hal ini membuat saya untuk lebih sadar akan dampak negatif dari teknologi dan lebih menyaring dampak dari teknologi.

Hasil Observasi

Daerah lingkungan sekitar saya adalah Jawa Barat, tepatnya Bandung. Saya menimba ilmu di kota tersebut dan berdasarkan pengalaman saya sebagai murid Sekolah Menengah Pertama (SMP) dan Sekolah Menengah Atas (SMA), saya telah menyaksikan berbagai kebudayaan yang tampak secara langsung di hadapan saya.

Pada saat saya SMP, kebudayaan di sekolah tempat saya menimba ilmu tersebut adalah adanya pelajaran bermain gamelan. Berdasarkan pelajaran yang saya terima dari guru yang mengajarkan saya saat itu, gamelan merupakan kebudayaan yang berasal dari Jawa. Gamelan ini sendiri merupakan sekumpulan alat musik yang dimainkan oleh beberapa orang hingga tercipta keharmonian nada, karena sejatinya memainkan gamelan ini pun butuh koordinasi dan kerja sama yang baik antar pemain musiknya. Beberapa alat musik yang terdapat pada gamelan ini adalah gendang atau kendang untuk mengatur tempo, kemudian ada juga gong, suling, gambang yang terdiri dari bilah-bilah kayu, serta ada juga bonang yang cara memainkannya sama seperti gambang, yaitu dengan cara dipukul. Adanya pelajaran bermain gamelan ini membuat saya penasaran, hingga akhirnya saya bertanya pada guru saya mengenai alasan diadakannya pelajaran bermain gamelan ini di sekolah. Beliau menjawab bahwa pelajaran bermain gamelan ini sejatinya diadakan agar para generasi Indonesia tidak melupakan budaya-budaya yang ada di negaranya sendiri, salah satunya dengan bermain gamelan ini.

Beranjak ke SMA, saya pun merasakan adanya budaya menggunakan pakaian kebaya putih (untuk perempuan) dan pangsi (untuk laki-laki) setiap hari Jumat. Saya merasa nyaman akan hal ini karena penerapan pemakaian pakaian budaya yang diadakan sekali seminggu menurut saya merupakan langkah kecil yang dapat dilakukan untuk meingkatkan kesadaran para anak muda untuk tidak melupakan kebudayaan negeri yang ditinggalinya. 

Berdasarkan tiga perspektif pemosisian kebudayaan atau 3T, yaitu Tatanan, Tuntunan, serta Tontonan, setiap kebudayaan yang kita lihat pasti mengandung atau bisa dilihat dari ketiga perspektif ini. Untuk bermain gamelan sendiri dapat dipandang sebagai tontonan, tapi di samping itu juga dapat dipandang sebagai tuntunan agar masyarakat kita lebeih sadar akan pentingnya kerja sama dan gotong royong, serta dapat dipandang sebagai representasi tatanan yang ada, di mana setiap masyarakat seyogianya memiliki peran mereka masing-masing dalam kehidupan bermasyarakat dan seharusnya berjuang sebaik mungkin dalam perannya masing-masing tersebut demi tercapainya keharmonisan. Selain itu, untuk pemakaian pakaian adat seperti pangsi dan kebaya sendiri bisa menjadi representasi identitas suatu daerah dari negeri kita, di samping itu juga menjadi tuntunan bagi para anak muda untuk tetap bangga akan kebudayaan negerinya, serta bisa juga menjadi tontonan yang baik dan menyenangkan untuk dilihat.

Tugas Identitas Mahasiswa

Hasil Observasi 

Lingkungan sekitar saya adalah daerah Jawa Barat. Kota-kota di Jawa Barat, berdasarkan informasi yang saya dapat dari berita-berita yang dapat saya baca secara daring, sebagian besar memberitakan bahwa kasus Covid-19 di Jawa Barat bertambah 2.719 kasus sehingga totalnya menjadi 347.287 kasus. Sementara itu kasus kesembuhan tercatat 1.245 sehingga total menjadi 312.448 orang. Adapun kasus kematian bertambah 28 orang sehingga menjadi 4.637 orang. Tak hanya itu, Ridwan Kamil pun menghimabu masyarakat untuk tetap patuh pada protokol kesehatan, namun berdasarkan pengamatan dan obervasi langsung saya pada daerah sekitar lingkungan saya, masih banyak warga yang tidak mematuhi protokol kesehatan. Tak jarang saya menemui warga yang tidak menggunakan masker dan berkeliaran di lingkungan sekitar saya. 

Sebagai mahasiswa, seyogianya memahami dan mengerti mengenai PoPoPe atau Posisi, Potensi, dan Perannya dalam kehidupan masyarakat. Diharapkan, mahasiswa dapat menerapkan pemahaman ini sebaik mungkin dan bisa memberi manfaat untuk ke arah yang lebih baik bagi masyarakat.

Posisi yang dimaksud di sini adalah bagaimana mahasiswa sebagai insan akademis yang memiliki tanggung jawab untuk selalu mengembangkan diri sehingga menjadi generasi yang tanggap dan mampu menghadapi tantangan masa depan. Dalam kasus ini, saya menginsyafi yang saya harus lakukan berkaitan dengan posisi saya. Saya berusaha sebaik mungkin untuk mengikuti segala aturan dan protokol kesehatan yang diberlakukan, sesuai dengan posisi saya yang berada pula dalam kelompok masyarakat. Tak hanya itu, sebisa mungkin saya akan memberi tahu warga-warga di lingkungan sekitar saya mengenai bahaya dan dampak pelanggaran protokol kesehatan bagi lingkungan sekitarnya dengan harapan agar mereka sadar dan merubah tindakan buruknya sehingga mau mematuhi protokol kesehatan.

Saya sebagai mahasiswa pun menginsyafi yang saya harus lakukan berkaitan dengan potensi saya karena seorang mahasiswa tentunya memiliki potensi untuk turut mengubah masyarakat dengan modal-modal yang dia miliki tanpa lupa bahwa mahasiswa pun merupakan bagian dari masyarakat itu sendiri yang tidak bisa dilepaskan dari kebudayaan lingkungan. Alhasil, saya sebisa mungkin menyebarkan mengenai awareness akan kasus covid ini di media sosial karena mahasiswa memiliki bekal teknologi yang cukup baik dan saya memanfaatkan bekal itu sebagai wujud kecil saya dalam membagikan pengetahuan dan kesadaran akan covid dalam masyarakat.

Mahasiswa pun berperan sebagai katalisator atau pembantu masyarakat. Mahasiswa dengan ilmu pengetahuannya dan posisinya sebagai bagian dari masyarakat haruslah mampu menjawab persoalan yang ada di masyarakat. Memang, mahasiswa ini bukanlah seperti pahlawan atau hero dan bisa menjadi juruselamat bagi segala masalah di dalam masyarakat, namun setidaknya mahasiswa tidak boleh melupakan perannya untuk memberi andil dalam menyelesaikan permasalahan yang ada di masyarakat. Untuk itu, saya, seperti yang sebelumnya telah saya sampaikan, mengambil peran dalam menyebarkan awareness akan kasus covid ini di bidang media sosial. Penyampainnya dapat berupa anjuran untuk stay at home, pentingnya hidup sehat dan berolahraga, serta menjaga mental tetap baik agar imun tetap terjaga di masa pandemi covid ini.

Mendifinisikan Peran

Perkenalan singkat, nama saya Gian, lahir di Bandung, 3 Maret 2002. Saya anak ke-2 dari 2 bersaudara. Saya bersekolah di SDK 6 sebagai SD saya, lalu lanjut ke SMPK 1 sebagai SMP saya, lalu setelah itu ke SMAN 3 sebagai SMA saya, lalu pada akhirnya saya berlabuh di ITB sebagai tempat saya berkuliah. Kelebihan saya adalah pantang menyerah dalam suatu tujuan serta sangat semangat dalam mengerjakan sesuatu yang disukai. Akan tetapi, saya juga memiliki kekurangan seperti sering menunda pekerjaan dan sering merasa panik pada beberapa situasi. Hobi saya adalah bermain sepak bola dan secara kebetulan sangat tidak menunjang perkuliahan saya sekarang dan pekerjaan saya nanti.

Cita-cita saya tidak pernah jelas sejak kecil, karena nyatanya cita-cita saya sejak kecil adalah menjadi pemain sepak bola. Ya, cita-cita menjadi pemain sepak bola bukanlah sesuatu yang menjanjikan di Indonesia (kata orang tua saya) dan seiring waktu saya sadar akan hal itu. Kurangnya support dari orang tua untuk mendukung hal tersebut menjadi cita-cita yang nyata (tentunya dengan pertimbangan-pertimbangan yang logis dan saya tidak menyalahkan mereka akan hal ini) tak mengubah ketekunan saya belajar selama masa-masa SD dan SMP walaupun tidak mengetahui kelak akan jadi apa. Namun, seiring waktu, saya melihat ketertarikan di bidang IPA dan menjadikan bidang tersebut menjadi sesuatu yang saya minati (walaupun saya tidak cukup baik di bidang tersebut). Maka pada akhirnya, cita-cita saya masih mengawang bebas di atas sana, namun jika memang "Apa cita-cita anda ?" memanglah sebuah pertanyaan yang harus saya jawab, mungkin saya akan jawab bahwa saya ingin bekerja di bidang industri farmasi dan yang terutama adalah menjadi apoteker.

Berhubungan dengan cita-cita saya tadi, menjadi apoteker berarti menjadi ahli obat dan itu berarti saya akan memiliki andil dalam kesehatan di masa depan nanti. Rencana saya tentunya sama dengan orang-orang dalam bidang saya pada umumnya, menyelesaikan masalah-masalah penyakit yang ada atau yang akan datang demi kemaslahatan bersama. Namun, sebelum itu saya harus lulus sarjana terlebih dahulu. Saya berencana untuk menyelesaikan studi s1 saya dalam waktu 4 tahun, lalu mengambil profesi apoteker setelah itu demi melancarkan rencana saya itu.

Hah!? Apakah Manusia harus Migrasi ke Planet Lain di Masa Depan??

Pindah ke Planet lain?? Biar apa??? Ngapainn!?

Ya, pertanyaan-pertanyaan di atas tiba-tiba muncul di pikiran saya ketika saya mandi. Memang bukan hal yang unik menemukan ide-ide nan absurd ketika kita sedang beraktivitas di kamar mandi. Seringkali saya menemukan gagasan-gagasan random ketika beraktifitas di kamar mandi, seperti "Mengapa harus apel yang jatuh ke kepala Newton ketika ia berada di bawah pohon dan bukan durian atau jangkar seberat 1 ton??" Sekian pembukaan atas pembahasan mengapa saya memutuskan untuk pindah ke planet lain membahas ide saya bahwa kehidupan kita sebagai manusia akan dihadapkan oleh sebuah tantangan di masa depan di mana kita harus terpaksa pindah ke planet lain. Terlepas dari cara saya membahas ide saya dengan tidak terlalu formal, saya pastikan pasti masih ada faedah dari tulisan saya kali ini, iya kan? 

Tantangan di masa depan dapat kita analisis melalui kacamata VUCA. Apa sih VUCA? VUCA bukanlah nama seorang gadis yang kamu temui secara tidak sengaja karena menabraknya saat mengantri tiket di bioskop, karena bahkan VUCA bukanlah nama orang sama sekali. VUCA adalah singkatan dari Volatility, Uncertainty, Complexity, dan Ambiguity. yaitu suatu konsep yang mendeskripsikan sifat perubahan yang sedang dan akan dihadapi dunia. VUCA didefinisikan sebagai sifat tantangan masa depan. VUCA adalah 'kacamata' yang dapat membantu kita memahami tantangan yang akan kita hadapi. Maka dari itu, pada kesempatan kali ini saya akan membahas mengenai tingginya potensi kita akan meninggalkan bumi ini karena kondisi bumi yang akan semakin memburuk di masa yang akan datang melalui kacamata VUCA.

VOLATILITY

Bukan lagi sering berubah, tapi bisa kita katakan kondisi bumi sekarang sudah sangat tidak menentu dan dapat berubah secara ekstrem suatu waktu. Mulai dari musim yang sudah pancaroba, bencana alam yang kadang tak terprediksi, juga kondisi bumi yang semakin menua dan kita pun sebagai manusia sering kali memilki andil dalam memperparah kondisi bumi kita ini, mulai dari berbagai polusi yang manusia ciptakan setiap harinya, juga berbagai kelalaian-kelalaian lainnya yang tanpa sengaja berdampak pula pada kondisi bumi ini, seperti yang sedang ramai akhir-akhir ini yaitu peristiwa gender-reveal party yang justru berujung tragis bagi lebih dari 20.000 hektar hutan di California (per 18 September). Tak menjadi hal aneh jika kita akan dipaksa secara alamiah untuk meninggalkan bumi ini cepat atau lambat di masa depan nanti.

UNCERTAINTY

Kondisi bumi kita ini tidak bisa kita ketahui dengan pasti. Mengingat luas bumi ini yang mencapai 510,1 juta km^2, maka sangat sulit untuk menentukan kondisi bumi pada setiap penjurunya secara pasti.

COMPLEXITY

Masalah-masalah yang terjadi di bumi ini (dalam bidang alam) biasanya memiliki keterkaitan kepada komponen-komponen lainnya di bumi, contoh terdekatnya ialah bencana alam. Misalkan saja terjadi gempa bumi atau tsunami di suatu daerah, biasanya musibah tersebut akan memiliki keterkaitan bagi daerah-daerah lain di sekitarnya, juga berdampak bagi aktivitas ekonomi masyarakat daerah-daerah tersebut. Tingkat keterkaitan tersebut pun berbanding lurus dengan kekuatan dari bencana alam yang terjadi, jadi mungkin saja akan ada bencana alam yang sangat dahsyat di masa mendatang yang akan menimbulkan kompleksitas yang sangat tinggi hingga memaksa manusia untuk pindah ke planet lain di masa depan.

AMBIGUITY

Letak, kekuatan, dan jenis ancaman yang akan mengancam kondisi bumi kita tidaklah jelas. Dia bisa datang secara alamiah, namun bisa juga datang dari diri kita sendiri. Tindakan-tindakan kecil dan dekat dengan kebiasaan kita seperti membuang sampah sembarangan memang tidak bisa terdeteksi satu-satu di bumi ini, namun secara bersamaan dampaknya akan terasa bagi kondisi bumi ini ketika dilakukan oleh manusia secara terus-menerus.

LAH, terus SOLUSI-nya apa dong?
Jujur, saya juga tidak memiliki solusi yang pasti karena saya tidak begitu paham mengenai kondisi bumi ini dan cara menanggulangi masalah-masalahnya. Lalu mungkin anda pembaca dari artikel ini akan berpikir, "Hmm.. lantas untuk apa orang ini menulis artikel sepanjang beberapa puluh atau ratus kata hanya untuk mengatakan bahwa ia tidak tahu solusi yang pasti mengenai apa yang ia bicarakan selama beberapa menit ini?" Jawabannya tidak ada pada saya, atau harus saya katakan tidak hanya ada pada diri saya, namun ada pada diri kita masing-masing. Setidaknya setiap hari kita bisa mengusahakan yang terbaik dari peran-peran kita dalam hidup kita masing-masing untuk kondisi bumi ini. Peran saya saat ini hanyalah mahasiswa. Ya, bahkan masih sangat baru jadi mahasiswa. Lalu mungkin anda pembaca akan bertanya "Lantas apa aksimu?" 

Jawaban saya,

"Yang bisa saya lakukan hanyalah membuang sampah pada tempatnya...
sambil berharap dan berdoa, saya tetap bisa tinggal di bumi ini dan memandang cakrawalanya sampai saya pergi meninggalkan segala keindahannya nanti."

Natural Phenomena : Gravity

Hello, my name is Gian and today I'm going to tell you the most usual natural phenomena that you always see in your life, it's called gravity. 

Gravity (from Latin gravitas, meaning 'weight'), or gravitation, is a natural phenomenon by which all things with mass or energy including planets, stars, galaxies, and even light—are brought toward (or gravitate toward) one another. On Earth, gravity gives weight to physical objects, and the Moon's gravity causes the ocean tides. The gravitational attraction of the original gaseous matter present in the Universe caused it to begin coalescing, forming stars – and for the stars to group together into galaxies – so gravity is responsible for many of the large-scale structures in the Universe. Gravity has an infinite range, although its effects become increasingly weaker on farther objects.

Gravity is most accurately described by the general theory of relativity (proposed by Albert Einstein in 1915) which describes gravity not as a force, but as a consequence of the curvature of spacetime caused by the uneven distribution of mass. The most extreme example of this curvature of spacetime is a black hole, from which nothing—not even light—can escape once past the black hole's event horizon. However, for most applications, gravity is well approximated by Newton's law of universal gravitation, which describes gravity as a force which causes any two bodies to be attracted to each other, with the force proportional to the product of their masses and inversely proportional to the square of the distance between them.

Gravity is the weakest of the four fundamental forces of physics, approximately 10³⁸ times weaker than the strong force, 10³⁶ times weaker than the electromagnetic force and 10²⁹ times weaker than the weak force. As a consequence, it has no significant influence at the level of subatomic particles. In contrast, it is the dominant force at the macroscopic scale, and is the cause of the formation, shape and trajectory (orbit) of astronomical bodies. For example, gravity causes the Earth and the other planets to orbit the Sun, it also causes the Moon to orbit the Earth, and causes the formation of tides, the formation and evolution of the Solar System, stars and galaxies.

Aryabhata
(476 CE - 550 CE)

The earliest instance of gravity in the Universe, possibly in the form of quantum gravity, supergravity or a gravitational singularity, along with ordinary space and time, developed during the Planck epoch (up to 10⁻⁴³ seconds after the birth of the Universe), possibly from a primeval state, such as a false vacuum, quantum vacuum or virtual particle, in a currently unknown manner. Attempts to develop a theory of gravity consistent with quantum mechanics, a quantum gravity theory, which would allow gravity to be united in a common mathematical framework (a theory of everything) with the other three forces of physics, are a current area of research.

History of Gravitational Theory

Aryabhata (the first of the major mathematician-astronomers from the classical age of Indian mathematics and Indian astronomy) first identified the force to explain why objects do not fall when the earth rotates. Brahmagupta described gravity as an attractive force and used the term "gruhtvaakarshan" for gravity.

Modern work on gravitational theory began with the work of Galileo Galilei in the late 16th and early 17th centuries. In his famous (though possibly apocryphal) experiment dropping balls from the Tower of Pisa, and later with careful measurements of balls rolling down inclines, Galileo showed that gravitational acceleration is the same for all objects. This was a major departure from Aristotle's belief that heavier objects have a higher gravitational acceleration. Galileo postulated air resistance as the reason that objects with less mass fall more slowly in an atmosphere. Galileo's work set the stage for the formulation of Newton's theory of gravity.

English phycist and mathematician,
Sir Isaac Newton (1642 - 1727)

In 1687, English mathematician Sir Isaac Newton published Principia, which hypothesizes the inverse-square law of universal gravitation. In his own words, "I deduced that the forces which keep the planets in their orbs must [be] reciprocally as the squares of their distances from the centers about which they revolve: and thereby compared the force requisite to keep the Moon in her Orb with the force of gravity at the surface of the Earth; and found them answer pretty nearly." The equation is the following:

${\displaystyle F=G{\frac {m_{1}m_{2}}{r^{2}}}\ }$

Where F is the force, m₁ and m₂ are the masses of the objects interacting, r is the distance between the centers of the masses and G is the gravitational constant.

Newton's theory enjoyed its greatest success when it was used to predict the existence of Neptune based on motions of Uranus that could not be accounted for by the actions of the other planets. Calculations by both John Couch Adams and Urbain Le Verrier predicted the general position of the planet, and Le Verrier's calculations are what led Johann Gottfried Galle to the discovery of Neptune.

A discrepancy in Mercury's orbit pointed out flaws in Newton's theory. By the end of the 19th century, it was known that its orbit showed slight perturbations that could not be accounted for entirely under Newton's theory, but all searches for another perturbing body (such as a planet orbiting the Sun even closer than Mercury) had been fruitless. The issue was resolved in 1915 by Albert Einstein's new theory of general relativity, which accounted for the small discrepancy in Mercury's orbit. This discrepancy was the advance in the perihelion of Mercury of 42.98 arcseconds per century.

Although Newton's theory has been superseded by Einstein's general relativity, most modern non-relativistic gravitational calculations are still made using Newton's theory because it is simpler to work with and it gives sufficiently accurate results for most applications involving sufficiently small masses, speeds and energies.

Equivalence Principle

The equivalence principle, explored by a succession of researchers including Galileo, Loránd Eötvös, and Einstein, expresses the idea that all objects fall in the same way, and that the effects of gravity are indistinguishable from certain aspects of acceleration and deceleration. The simplest way to test the weak equivalence principle is to drop two objects of different masses or compositions in a vacuum and see whether they hit the ground at the same time. Such experiments demonstrate that all objects fall at the same rate when other forces (such as air resistance and electromagnetic effects) are negligible. More sophisticated tests use a torsion balance of a type invented by Eötvös. Satellite experiments, for example STEP, are planned for more accurate experiments in space.

Earth's Gravity

Every planetary body (including the Earth) is surrounded by its own gravitational field, which can be conceptualized with Newtonian physics as exerting an attractive force on all objects. Assuming a spherically symmetrical planet, the strength of this field at any given point above the surface is proportional to the planetary body's mass and inversely proportional to the square of the distance from the center of the body.

That value, denoted g, is g = 9.80665 m/s² (32.1740 ft/s²).The strength of the gravitational field is numerically equal to the acceleration of objects under its influence. The rate of acceleration of falling objects near the Earth's surface varies very slightly depending on latitude, surface features such as mountains and ridges, and perhaps unusually high or low sub-surface densities. For purposes of weights and measures, a standard gravity value is defined by the International Bureau of Weights and Measures, under the International System of Units(SI).

The standard value of 9.80665 m/s² is the one originally adopted by the International Committee on Weights and Measures in 1901 for 45° latitude, even though it has been shown to be too high by about five parts in ten thousand. This value has persisted in meteorology and in some standard atmospheres as the value for 45° latitude even though it applies more precisely to latitude of 45°32'33".

If an object with comparable mass to that of the Earth were to fall towards it, then the corresponding acceleration of the Earth would be observable.

Assuming the standardized value for g and ignoring air resistance, this means that an object falling freely near the Earth's surface increases its velocity by 9.80665 m/s (32.1740 ft/s or 22 mph) for each second of its descent. Thus, an object starting from rest will attain a velocity of 9.80665 m/s (32.1740 ft/s) after one second, approximately 19.62 m/s (64.4 ft/s) after two seconds, and so on, adding 9.80665 m/s (32.1740 ft/s) to each resulting velocity. Also, again ignoring air resistance, any and all objects, when dropped from the same height, will hit the ground at the same time.

According to Newton's 3rd Law, the Earth itself experiences a force equal in magnitude and opposite in direction to that which it exerts on a falling object. This means that the Earth also accelerates towards the object until they collide. Because the mass of the Earth is huge, however, the acceleration imparted to the Earth by this opposite force is negligible in comparison to the object's. If the object does not bounce after it has collided with the Earth, each of them then exerts a repulsive contact force on the other which effectively balances the attractive force of gravity and prevents further acceleration.

The force of gravity on Earth is the resultant (vector sum) of two forces: (a) The gravitational attraction in accordance with Newton's universal law of gravitation, and (b) the centrifugal force, which results from the choice of an earthbound, rotating frame of reference. The force of gravity is the weakest at the equator because of the centrifugal force caused by the Earth's rotation and because points on the equator are furthest from the center of the Earth. The force of gravity varies with latitude and increases from about 9.780 m/s² at the Equator to about 9.832 m/s² at the poles.

5 Places on Earth where Gravity Becomes Zero

Let's get to the best part, have you ever find a place where your foot don't even step on the ground anymore ? Well if you haven't, let's see these 5 places !

Because of the gravitational force we walk on the earth, meaning that it binds everything at the surface of the earth. But there are some places on earth where the gravitational force becomes zero and strange phenomena occur. Through this article, you will learn about the places where gravitational force does not work or becomes zero.

Gravity is the force that holds the sun and other planets in the solar system. This is the force that holds us and everything on the surface of the earth or draws towards the center of the Earth. In simple words, if you bend more, then you can fall, but where the gravitational force does not work, instead of after bending you will not be able to fall. We all know about Newton's popular story that when he was sitting under an apple tree, an apple fall on his head and suddenly he started thinking why anything falls from the top. After this he propounded the law of gravity or law of universal gravitation, according to which the force of attraction acting between any two particles is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. But there are some places where gravity becomes zero on earth or where gravitational force does not work.

1. Mystery Spot, Santa Cruz California

Source: www.firesideinnsantacruz.com
This place was discovered in 1939 by a group of surveyors and was opened to the public by George Prather in 1940. They stated that during the time of searching the place they felt that some different forces work here. They claim that there is some different type of irregularity in the magnetic field here and this magnetic irregularity is seen only in 150 square feet of the circular area, which is also called Mystery Spot. This is a place where you will see strange irregularities in gravity, such as flowing of water in the upward direction, deflection of magnetic compasses at different angles, changes in the size of people and things. At this place you can also stand at an angle without falling down.

2. St. Ignace mystery spot, Michigan

Source: www.sideshowworld.com
When some people were doing surveys in the 1950s, suddenly their devices stopped working secretly, when they conducted extensive surveys of this place, they found that it was only happening in the area of 300 square feet. Not only this, animals in this area also refrain from coming. Even here also some strange phenomena are seen due to the lack of gravitational force, such as standing on the wall, people can do a variety of tricks such as keeping the chair on the wall and enjoy sitting in which two feet of the chair remains on the wall and two bizarre in the air, after staying here for a long time, you will feel that your head is getting lighter.

3. Cosmos Mystery Area, Rapid City

Source: www.cloudfront.net.com
Moving to this place, you will see some trees which are mysteriously bowed. Like mystery spots, you can stand here without falling at an angle. Along with this some more phenomena’s were seen like the ball going upward and not much that when you went upwards places felt to be changed.

4. Spook Hill, Florida

Source: www.florida-backroads-travel.com
This is a gravity hill place where the car appears to roll up the spooky hill which is an optical illusion.  If you stop your vehicle or make it neutral, then you will see that it is being pulled up towards the mountain. When the Native-Americans eventually lost their land to settlers, the pioneer mail riders noticed their horses labouring downhill, which led to them nicknaming the spot “Spook Hill”.

5. Magnetic Hill, Leh

Source: www.cloudfront.net.com
It is a small route which stretches about 30 km from Leh towards Kargil and is known as the Magnetic Hill of Ladakh. On this special route of the Srinagar-Leh highway, you would see that the road ahead going uphill. However, if you turn off the engine and keep your vehicle in neutral, then on its own, it will start moving slowly and can go up to 20 kilometers per hour. It is said that behind this mysterious phenomena there is a magnetic force that pulls the car uphill. Even the aircraft passing over this region increases their altitude to avoid magnetic interference.
From this article we come to know that there are some places on the earth where strange or mysterious phenomena occurred and is said that it is because of the gravitational force which becomes zero.

Well, that's all from me about natural phenomena, hope you like it !!

Tur Budaya Experience 2019

Hi, my name is Gian and today I'm going to tell one of the most catchy and glorious moment of my life. It's when I experience this memorable event in my school called Tur Budaya 2019. It's like an ordinary vacation, but comes with more cultural experience that makes us feel more grateful to be Indonesian people. After visiting Bali, my feeling about this country is never be same. Now I know how beautiful Indonesia is and I know that I must be proud to be Indonesian people and it is our responsibility to maintain the beauty of our country. Now let's get to the main course.

The togetherness at the Airport
(The preparation before the exciting Journey)

On the first day of Turbud (17th of March 2019), SMAN 3 Bandung arrived at Husein Sastranegara Airport. Our school's tour divided into 3 groups. The first one departed for Bali before 9 a.m and the last one departed for Bali at 1 p.m. On 10 o'clock, we were given lunch before we got on our plane. The flight duration was about 115 minutes to 2 hours.

Me while taking a pose like I'm
holding on the GWK Statue

After 2 hours flew through the air, we arrived at Ngurah Rai International Airport, located in Bali. We arrived there at ten past sixteen (in central Indonesian time or usually called as WITA). We took our luggage and all of our belongings to our bus that already parked at the airport's parking lot.

The beauty of Jimbaran Beach
(more like see the heaven, isn't it ?)

Then, we continued our vacation to Jimbaran with a dinner purpose in A'roma Restaurant. The Jimbaran Beach isn't really wide and it had white sand. There were so many seafood restaurant. We enjoyed the dinner that served with beautiful sunset view and melodious voice of a local singer, but everything went wrong when suddenly the heavy rain invaded the dangdut song and all of our dishes. We all ran to the inside of A'roma Restaurant and continued the dinner there. After full, we went to Quest Hotel to get some rest. We arrived at the Quest Hotel at about 8 p.m WITA.

tried to keep calm and held the turtle

the lil' black birdie

On the second day of Turbud, me and my roommates woke up at 4 a.m. We did our daily routines before starting the day, like worshipped and of course took a bath. Then, we took a breakfast at half past seven WITA. We left for Tanjung Benoa at half past eight WITA after took a breakfast. In Tanjung Benoa we can do so many kind of watersports. We arrived at Tanjung Benoa at 9 a.m. Then, I prepared myself for the deadly, bone-breaking, heart pumping watersport in Tanjung Benoa (well, thats just a hyperbole, in case to make me look like a watersport maniac, obviously I never do watersport before).

Look at all those scared face, we
really good at faking our face

Played gleefully in the sand like
we never see sand before

Firstly, I started my deadly, bone-breaking, heart pumping watersport journey by visiting the Turtle Island. Me and my friends visisted the Turtle Island using a motorboat. The trip was really thrilling (well, thats just my other hyperbole, obviously it's just an ordinary water trip). The Turtle Island got a turtle conservation place in it. There is not only turtle, but also other animals like bats, birds, snakes, etc. After that, we went back to Tanjung Benoa. After that thrilling ride to Turtle Island, the journey just couldn't get any better. I invited 3 of my friends to join me in the breathtaking donut ride. It's a watersport where you ride a donut with your friends and the donut is threw by the motorboat driver who tie the donut to his motorboat. The watersport really made my adrenaline pumped. It's totally worthed.

Look how big is the GWK statue !!
2nd biggest statue in the world !

After that, we stopped by Puja Mandala, the worship center for 5 religions with an area of 2 hectares. Then, we continued the vacation to Pandawa Beach. It's located at the south of Kuta. This beach usually called as the secret beach, because of the location of the beach is between two big cliffs. After we took a lot of photos there, we continued the vacation to visit the Garuda Wisnu Kencana or usually called as GWK. GWK is located about 40 kilometers at the south of Denpasar. In this location, we can see such a gigantic statue stand firmly in its place. The statue depicts god of wisnu while riding garuda. After we visited the second biggest statue in the world, we watched Devdan Show that located in Benoa, Bali. This show presented traditional dance and modern dance mixed up with Indonesian cultural wealth. This show is extremely fascinating.

The Tirta Empul's holy water sprays

The next day, we woke up at 4 a.m and did the same thing like yesterday. We also took a breakfast at half past seven and then we ready to start our third day in Bali by visited Tirta Empul first. Tirta Empul is well known for its holy water. Hindus usually seek sanctification or purification in this place because it has 13 holy water sprays. There are a lot of Hindus that also do worship activities here. After we visited Tirta Empul, we continued the vacation for lunch in Kintamani. We arrived at the one and only halal certified restaurant. We could enjoy all of the 25 delicious lunch menus here because this is one of the "all you can eat" restaurant.

After the delicious dishes ran out, we visited Penglipuran Village located in Bangli Regency, Bali. This village is famous for it's traditional culture that still run in the villager's blood and in all of the village structure. The building architecture and the land processing still follow the tri hita concept.

Well, it's hard to gather together and took this photo
because actually it blocked the pedestrian path, but it's worthed

This is the cleanest village in Indonesia and one of the cleanest village in the world. I'm really proud to be Indonesian people and we need to keep this beauty for ages so that our next generation can still see this beauty. We were walking and taking some photos when suddenly a heavy rain invaded our vacation again. Aww, snap !! I said. Then, we took cover in one of the villager's house and bought some souvenirs there. After that, we went back to our bus and went back to Quest Hotel to prepare for the gathering night or usually called as makrab. The makrab was held in Nirmala Hotel. The makrab was held until 12 p.m. After that, we went back to Quest Hotel and took a rest.

My mind is still defying gravitiy. It's still floating
in the beauty of Bali

On the fourth day, as usual, we did our morning daily routines after we woke up, but the difference was today we needed to pack all of our belongings because today we needed to check out of the Quest Hotel. This was the last day in Bali. I didn't feel really sad to leave Bali because I knew Bali was really exciting and beautiful, but I remembered that I wasn't belong here. I needed to go back and see my family in Bandung (and also feed my lovely dog named Hesh). Bandung was still my lovely home, but I couldn't deny the fact that Bali was really beautiful and unforgettable.

Walking along the beach to proof
that earth isn't flat

So, we continued the vacation for Kuta Beach. Kuta Beach is the most famous beach in Bali. This beach is suitable for surfing lovers because the waves are good and the atmosphere here is very nice. This beach is surrounded by several hotels, restaurants, villas, mall, etc. We've got free times here to explore this beach and it's surrounding. We walked along the beach while taking some photos and also visited a mall near the beach.

Head in the clouds. Couldn't feel
any better than this time.

Abyan was bitten by a kitten near
Bedugul Temple. Couldn't help him,
cause it's so funny haha 

After a tiring walk, we went back to our public transportation and continued the vacation for Krisna Souvenir Center. We could buy some souvenirs there, like clothes, foods, accessories, etc. We also had a lunch there. We had a lunch at R.M. Grafika located in front of Krisna Souvenir Center. After had a lunch, we visited Tanah Lot. I felt really relaxed while stood in this place. The wind, the wave, the atmosphere are so great. We also visited Bedugul Temple after visited Tanah Lot. This temple is famous for its appearance in 50 thousand rupiahs money. This temple was so beautiful and so relaxing too

Looked the same, isn't it ? Yeah, beautiful too

Well, that was the last one, so after that, we went to Gilimanuk Harbour. The exciting Bali journey ended up in this harbour. So much happiness, so much laugh, and so much to remember. For the dinner, we ate some food in R.M. Kenanga Singaraja. On the way home, we still saw the famous Suramadu Bridge located in Surabaya. The bridge was pretty awesome. We spent our way home times by sleeping, talking, laughing, and had a lunch in Warung Wulan.

The trip might be end,
but the memories are everlasting

Finally, we arrived at Gubeng Station located in Surabaya. We used an executive train as our transportation, on 16.30 WIB (West Indonesian Time). At last, we arrived at Bandung Station on 05.40 WIB and then went back to our home.

Safe and sound at Bandung Station
