Abstract

The exploration of oil and gas, especially in Indonesia is experiencing various challenges and varying degrees of difficulty. In this research, the researcher tries to make a 3D modeling from gravity data, where the model will show a structure to determine the central coordinates for drilling. Pertamina has carried out drilling at a location in NTT and it turns out that the well does not produce oil and gas, even though the log data reads an oil showing that the area should have the prospect of producing oil, but the wells that have been drilled do not show any oil or gas, therefore the researchers tried to make a 3D model determine the structure around the production well. In this research, it was seen that the area of the previous drilling point had deviated from the top of the up dome and it was also seen in this structure that the area was deviated by about 3 kilometers and depth must exceed 526 m, the researcher concluded that the drilling point must be at X, Y coordinates.

Abstract

Numerical simulation of the satellites’s orbital velocity and orbital period on the earth has been performed. This research aimed to study satellites’s orbital velocity and orbital period on the earthbased on position function. Velocity equation has been gotten from modification equation of centripetal force and equation of earth’s gravitational force. Through numerical calculation of orbital velocityand orbital period equation by function discretization, we got that the velocity and period of satellite at height of 30000 km above the earth’s surface are 3.31 km/s and 19.18 hours, respectively.

Abstract

Dalam penelitian kali ini peneliti mencoba membandingkan hasil pengukuran medan magnet dan medan listrik pada ltiga medan yang berbeda-beda yaitu di daerah pemukiman, perkebunan dan tanahg lapang, hal ini peneliti lakukan untuk mengetahui kekuatan medan magnet dan medan listrik apakah masih dalam ambang batas aman.  Hal ini penting dilakukan dikarenakan kita tahu bahwa dalam pembangunan jaringan kelistrikan baik SUTET  (saluran udara tegangan ekstra tinggi) ataupum SUTT (saluran udara tegangan tinggi), sering sekali mendapat tentangan dari beberapa ormas seperti LSM yang menentang dan beberapa masyarakat yang tidak terima bahwa daerah pemukimannya dilalui oleh jalur SUTT maupun SUTET. Dalam pengukuran peneliti menggunaklan alat untuk mengukur medan magentik dan medan listrik yaitu Alat uji ELF Survey meter ETS-Lindgren. Dari hasil pengamatan kuat medan listrik sangat di pengaruhi oleh benda-benda di sekitarnya karena medan listrik tidak dapat menembus benda-benda isolator, medan magnet memiliki sifat dapat menembus benda-benda di sekitarnya, hal ini sesuai dan hasil pengukuran juga membuktikan bahwa kuat medan listrik dan medan magnet dari pajanan SUTT masih jauh di bawah ambang batas aman yang telah di tetapkan oleh WHO.

Abstract

A numerical simulation of the Satellites’ orbital velocity and satellites’ escape velocity has been performed. This research aimed to study Satellites’ orbital velocity and orbital escape velocity based on position function. Velocity equation has been gotten from modification equation of centripetal force and equation of earth’s gravitational force. Through the numerical calculation of orbital velocity and escape velocity equation by function discretization, we got that the orbital velocity and escape velocity of the satellite at height of 30.000 km above the earth’s surface are 3.31 km/s and 4.68 km/s, respectively.

Abstract

Telah dilakukan rancang bangun alat peraga pembelajaran fisika pada materi Gaya Lorentz. Tujuan dari penelitian ini yaitu menghasilkan alat peraga Gaya Lorentz. Rancang bangun ini menggunakan alat seperti obeng, pemotong akrilik, gunting, bor listrik, dan multimeter. Sedangkan bahan yang digunakan yaitu akrilik, kabel, baut, pipa kuningan, magnet neodium, colokan pisang, baterai, kabel buaya dan aluminium foil. Hasil pengujian alat peraga Gaya Lorentz ini menghasilkan arus listrik rata-rata 1,972 A, muatan medan magnet 0,3 Tesla, panjang penampang 0,1 m. Sehingga didapatkan hasil rata-rata perhitungan Gaya Lorentz yaitu 2,372 N.
