Abstract

A simple simulations on Newton’s cooling law has been performed. This simulations aims to study correlation of the newton cooling constant at temperatures to cooling times. This reseach is displayed in GUI Matlab (Guide Using Interface).  The input required is initial temperature, ambient temperature, cooling constant, and cooling time. Through numerical calculation of the Newton’s cooling equation with Eulerian Method, we got that the time to reach the ambient temperature of each cooling constant is 59 seconds, 31 seconds, and 20 seconds respectively.

Abstract

The purpose of this research is to produce a development product in the form of a Magnetic Levitation Train miniature model that can be used by teachers and students in the physics learning process on magnetic force material in class XII. This study uses research and development methods. The research was conducted through several stages, namely the first stage reviewing curriculum standard notes. The second stage is the design of the tool, making a miniature model of the Magnetic Levitation Train and the use of a miniature model of the Magnetic Levitation Train in the learning process. The third stage is the implementation stage, the miniature model of the Magnetic Levitation Train was tested on high school student of class XII to measure students against the miniature model of the Magnetic Levitation Train as a tool to help students understand the concept of magnetic force. The instrument uses a Likert Scale. With three stages, the researcher succeeded in making a miniature model of the Magnetic Levitation Train that was worthy of being one of the learning media on magnetic force material by obtaining information that the validation results by experts, material personnel and students obtained a very good level of measurement which was in the interpretation range of scores 80-100% so it is necessary to develop a miniature model of the Magnetic Levitation Train to be even better in further research.

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

Simulating the temperature distribution of iron and brass metal thin plates based on matlab has been performed. This simulation aimed to study iron plate and brass plate conductors of the temperature distributionbased on conduction mechanism on cartesian coordinate system. The initial temperature in all parts of the thin plate is room temperature, except at left side and right side of the plate is 100 oC. Through numerical calculation of heat conduction equation by Finite Difference Method, we got that the temperature at center thin plate for 10 second is 63,26oC and 62,08 oC for brass thin plate and iron thin plate, 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.

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.
