Abstract

Telah dibuat koil (solenoida) dan inti koil yang bervariasi. Koil divariasikan dengan jumlah lilitan: 50 lilitan, 100 lilitan, 150 lilitan dengan panjang 5 cm dan diameter 3,5 cm, sedangkan inti koil divariasikan dari beberapa material seperti Fe (besi), Cu (tembaga), dan Al (aluminium) dengan panjang 5 cm dan diameter 3 cm. Koil ini dirangkai secara seri dengan resistor yang memiliki resistansi 150 Ω, sumber tegangan dan saklar, kemudian dilakukan pengukuran tegangan induktor dan resistor pada koil. Pengukuran ini dilakukan untuk koil tanpa inti dan koil dengan tambahan inti Fe, Al, serta Cu. Berdasarkan hasil pengukuran diperoleh tegangan induktor menurun seiring pertambahan waktu, besarnya tegangan tersebut juga dipengaruhi oleh medan magnet koil. Penambahan inti Fe pada koil 150 lilitan menghasilkan tegangan induktor sebesar 2,54 volt saat t = 5 detik, sedangkan penambahan inti Cu menghasilkan tegangan induktor sebesar 0,42 volt pada waktu yang sama. Tegangan resistor pada koil 100 lilitan dengan inti Fe adalah 0,21 volt pada t = 5 detik, namun begitu intinya diganti dengan Cu tegangannya menjadi 2.42 volt. Ini berarti koil dengan medan magnet besar akan menghasilkan tegangan induktor yang besar sedangkan tegangan resistor utuk koil dengan medan magnet besar akan bernilai kecil.Kata Kunci:Inti Koil, Tegangan Resistor, Tegangan Induktor, Medan Magnet

Abstract

Conflict between Rokan Hulu District and Kampar District in Riau Province  is conflict about the seizing territory of five villages on the border in both districts. Litigation process which was persued by the central government inresolving the conflict in the border of both districts did not solve that problem. Both districts do not accept the decision that has been arranged by the central government. It was proved by the allocation of village budget for the five villages from the both districts. This also lead to social tension and conflict in the community of five villages which then make the conflict more widespread. This study used a qualitative method and aim to describe the conflict resolution in the determining the boundary between District of Rokan Hulu and District of Kampar. Konflik antara Kabupaten Rokan Hulu dengan Kabupaten Kampar di Provinsi Riau merupakan perebutan lima desa yang ada diperbatasan kedua Kabupaten. Jalur Litigasi/peradilan yang ditempuh oleh pemerintah pusat dalam menyelesaikan konflik di tapal batas kedua kabupaten tidak menyelesaikan persoalan. Kedua kabupaten tidak menerima keputusan yang telah ditetapkan oleh pemerintah pusat dengan masih diberikannya Alokasi Dana Desa di lima desa oleh masing-masing kabupaten. Hal ini kemudian memicu ketegangan dan konflik sosial di masyarakat lima desa yang membuat konflik semakin meluas. Penelitian ini menggunakan metode kualitatif dan bertujuan untuk memaparkan resolusi konflik dalam penentuan tapal batas di Kabupaten Rokan Hulu dan Kabupaten Kampar.

ABSTRACT The BSM Program is a National Program aimed at eliminating the barriers of poor students participating to school by helping poor students gain access to appropriate education services, prevent dropping out, attract poor students to return to school, help students meet needs in learning activities, support the Compulsory Education Program Basic Nine Years (even to the upper secondary level), as well as helping the smoothness of school programs. Through the BSM Program it is expected that school-aged children from poor households / families can continue to go to school, not dropping out of school, and in the future it is hoped that they can break the poverty chain that their parents are currently experiencing. The BSM program also supports the governments commitment to increase education participation rates in poor and remote districts / municipalities as well as to marginalized groups. This program is a direct aid to students and not a scholarship, because based on students economic conditions and not on merit (scholarship) considering the condition of the students, while scholarships are given taking into account student achievement. In this research used support system with Technique for Order Performance method by Similarity to Ideal Solution or TOPSIS. This method is known as the weighted summing method. The basic concept of the TOPSIS method seeks a weighted sum of performance ratings on each alternative on all attributes. The TOPSIS method requires the process of normalizing the decision matrix (X) to a scale comparable to all the alternatives available so as to produce a ranking.

Abstract

Masuknya aliran panas dari bawah reservoir ke dalam medium berpori di dalamnya mempengaruhi kondisi tekanan, entalpi, dan temperatur di dalam reservoir. Hal ini terjadi karena panas mengalir dari daerah bertemperatur tinggi ke daerah bertemperatur lebih rendah. Panas mengalir melalui daerah patahan (fracture zone) yang memiliki permeabilitas dan porositas lebih tinggi dari daerah sekitarnya di dalam reservoir untuk kemudian terjadi perpindahan panas secara konduksi menuju daerah sekitarnya. Tulisan ini mensimulasikan proses perpindahan panas dengan mengamati distribusi temperatur dan aliran fluida pada medium berpori. Metode numerik yang digunakan adalah metode elemen hingga. Hasil yang ditampilkan adalah distribusi tekanan, kecepatan aliran fluida, dan distribusi temperatur dan kemudian diinterpretasikan.Kata kunci: permeabilitas, porositas, kecepatan, distribusi temperatur, metode elemen hingga.
