Abstract

Kualitas distribusi energi listrik secara praktis ditentukan dari drop tegangan dan faktor daya. Batasan drop tegangan terstandar 10% < tegangan kerja nominal < 5% dan faktor daya terendah 0,85. Untuk menganalisa kualitas sistem kelistrikan Bandara Yogyakarta International Airport (YIA) diperlukan perhitungan aliran daya yang tepat diantaranya penerapan metode Newton Raphson, Fast Decouple dan Gauss – Seidel. Tingkat kerumitan penyelesaian aliran daya sistem kelistrikan Bandara YIA secara manual cukup tinggi. Oleh karenya program aplikasi Etap versi 12.6 dapat menyelesaikan permasalah tersebut. Dengan membandingkan ketiga metode tersebut, pada iterasi 99, indeks presisi 10-4 metode Newton Raphson dan Fast Decouple memiliki kesederhaaan implementasi, effisiensi perhitungan dan keandalan yang tinggi dibandingkan Gauss – Seidel. Hasil running Newton Raphson dan Fast Decouple memiliki kesamaan hasil yaitu faktor daya dibawah standar 5 titik beban dari 41 titik beban (12,19%) dan drop tegangan tertinggi 2,48 %, Gauss-Seidel dengan iterasi 2000, nilai indeks prsisi 10-6 menghasilkan 7 titik beban (17,07%). Dengan demikian metode Newton Raphson atau Fast Decouple dapat digunakan untuk analisa kualitas sistem kelistrikan Bandara YIA. Kesimpulan hasil running menyimpulkan bahwa kondisi kualitas sistem kelistrikan Bandara YIA masih diatas standar.

Abstract

Hassan Hanafi is one of the Islamic thinkers who has developed a multidisciplinary method of thinking, at least combining Islamic scientific traditions and Western methods which emphasize methodological aspects, his popular thought is the conception of the Islamic Left which offers the idea of ​​renewal that includes four central ideas: revitalization of classical Islamic treasures, answer the challenges of civilization, seek revolutionary elements in religion and create Islamic national integrity. These four ideas are then relevant to the author by looking at the methods of preaching, especially in Sambas. The aspect that can be seen in this thinking is the ability to see the achievements of the previous ulama/dai who have been able to preach Islam so that it becomes the majority religion in the Sambas community. The ability to integrate Islamic teachings and aspects that smell local in this term is called local wisdom. In expressing this idea, the writer uses an intellectual history approach that focuses on the existence of Zeitgeist (the soul of the times) of the past Sambas community.

Abstract

Meningkatnya kebutuhan energi listrik di wilayah Kabupaten Gunung Kidul disebabkan oleh tumbuhnya industri dan pariwisata seperti perumahan, kafe, dan mulai dibangunnya pabrik-pabrik baru. Untuk mengantisipasi keadaan tersebut, penelitian ini diawali dengan menganalisis bagaimana pasokan energi listrik hingga 25 tahun ke depan dapat terpenuhi. Analisis dilakukan dengan menggunakan regresi linier yang memperhitungkan pertumbuhan beban daya listrik pada kategori beban sosial, rumah tangga, dunia usaha, industri dan pariwisata dengan menggunakan data tahun 2019-2021. Hasil penelitian menunjukkan bahwa pada tahun 2046, kebutuhan listrik akan mencapai 103.521 MVA dimana kebutuhan energi listrik harian sebesar 2.112 GWH dengan rata-rata pertumbuhan tahunan sekitar 1,8%. Artinya, dalam 25 tahun ke depan perlu adanya peningkatan daya listrik sebesar 31.521 MVA dibandingkan saat ini.

Abstract

Abstrak Penelitian ini bertujuan untuk mengetahui perbandingan model pembelajaran kooperatif tipe Examples Non-Examples dan Picture And Picture terhadap hasil belajar siswa pada materi perangkat keras internet ditinjau dari motivasi belajar di kelas XI SMA Negeri 1 Toba Kabupaten Sanggau. Metode penelitian menggunakan metode eksperimen, bentuk factorial design. Sampel dalam penelitian ini adalah kelas XI IPS 2 dan XI IPS 3 yang dipilih dengan menggunakan teknik cluster random sampling. Instrumen penelitian berupa tes bentuk soal pilihan ganda dan angket. Data yang diperoleh dianalisis menggunakan anava dua jalur. Hasil uji anava menunjukkan: 1) Terdapat perbedaan hasil belajar sesudah diberi perlakuan dengan model pembelajaran kooperatif tipe Examples Non Examples dan Picture and Picture pada materi perangkat keras internet di kelas XI SMA Negeri 1 Toba Kabupaten Sanggau dengan model Examples Non Examples, 2) Terdapat perbedaan hasil belajar siswa yang memiliki motivasi belajar tinggi dengan siswa yang memiliki motivasi belajar rendah pada materi perangkat keras internet di kelas XI SMA Negeri 1 Toba Kabupaten Sanggau, 3) Terdapat interaksi model pembelajaran dengan motivasi belajar terhadap hasil belajar siswa pada materi perangkat keras internet di kelas XI SMA Negeri 1 Toba Kabupaten Sanggau dengan nilai Model Examples Non Examples. Abstract This study aims to determine the comparison of cooperative learning models of the Examples Non-Examples and Picture And Picture types on student learning outcomes on internet hardware material in terms of learning motivation in class XI SMA Negeri 1 Toba, Sanggau Regency. The research method uses the experimental method, a form of factorial design. The sample in this study was class XI IPS 2 and XI IPS 3 which were selected using cluster random sampling technique. The research instrument was a test in the form of multiple choice questions and a questionnaire. The data obtained were analyzed using two-way anava. The results of the anava test show: 1) There are differences in learning outcomes after being treated with cooperative learning models of the Examples Non Examples and Picture and Picture types on internet hardware material in class XI SMA Negeri 1 Toba, Sanggau Regency with the Examples Non Examples models, 2) There are differences learning outcomes of students who have high learning motivation with students who have low learning motivation on internet hardware material in class XI SMA Negeri 1 Toba Sanggau Regency, 3) There is interaction of learning models with learning motivation on student learning outcomes on internet hardware material in class XI SMA Negeri 1 Toba, Sanggau Regency with Model Examples Non Examples.
