Abstract

In a highly developed era, of course, it will require the use of electricity to continue to increase, and the problem is to meet the high electricity demand, on the other hand the construction of electricity infrastructure that takes a long time will hamper the supply of electricity, therefore renewable energy sources are needed to overcome this problem. that's why we tried to make Magneto Electrical. Magneto Electrical is a Future Energy Source created to provide a safe, efficient, and environmentally friendly source of electrical energy. The purpose of this research is to design and manufacture Magneto Electrical: Future Energy Sources. The research method used is research and development (R&D). This research method is used to research so that it can produce new products and then test their effectiveness. Magneto Electrical works based on Faraday's Law, namely when a conductor is rotated in a magnetic field so that it cuts the magnetic lines at the end of the conductor, an emf (line of electric force) will be generated. Through this research, researchers have succeeded in designing and making Magneto Electrical: Future Electrical Energy Sources. By utilizing the repulsion between magnets so that motion energy is produced which is then converted into electrical energy. From the tests that have been carried out, it was found that the tool made is capable of producing 15 Volts of electrical energy.

Abstract

The vehicle is an important requirement for daily activities. The increasing number of vehicles in Indonesia from year to year correlates with the worsening air quality, especially in big cities like Jakarta. Data also shows that 70% of air pollution in Jakarta comes from motorized vehicles that use fossil fuels. One source of energy that can be an alternative solution is electric-powered vehicles because they have advantages, which are not producing pollution. Electric vehicles generally use lithium batteries as a source of electric power. Lithium batteries that have been used up are generally just thrown away without going through the processing so that they will contaminate water and soil. Therefore, we want to make vehicles that are not dependent on fossil fuels, produce no pollution, and can do auto charging electric so they don't rely on PLN electricity. This vehicle can charge independently because it has an electromagnetic coil on the rear wheel that will produce GGL induction from the wheel rotation when the bike is moving. We call this vehicle MOBERAK (Environmentally Friendly Fuel-Free Motorbike).

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

This study aims to develop learning media in the form of Applications on Momentum and Impulse Materials using the Ispring Suite. In this case, the researcher develops learning media in the field of education that integrates with the development of information and communication technology, namely by utilizing cell phones which basically almost 99% of students already have. The learning media developed is an application called Pemodim. The research method used in this research is the research and development method with the ADDIE development model (Analyze, Design, Development, Implementation, and Evaluation) which is a learning design model based on an interactive systems approach. This mod was created using PowerPoint and then Published using the Ispring Suite Software into HTML, after that it was converted into an Android application form with the help of Website 2 APK Builder Software. This Pemodim learning media is equipped with material applications in the form of text and also images and learning videos so that it becomes a device solution in supporting education, especially Physics. This android-based learning media is also said to be feasible to use based on validation from media experts, material experts, linguists, and education practitioners. The average total score of 88% for the media expert validation assessment, the average total score of 90% for the material expert validation assessment, the average total score of 84% for the linguist validation assessment, and the average total score of 89 % for the validation assessment of education practitioners, each of which results fall into the "Very Eligible" criteria. In addition, a limited test has been carried out on 7 students getting an average score of 87% and the test was extended to 20 students getting an average score of 90% so the total is 27 students in the very good category.

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.
