Electrical energy transfer is the ever-evolving transfer of energy to operate electronic devices. Wireless transmission of electrical energy has many efficient advantages compared to using cables, namely the use of fewer wires and increased convenience when using electronic devices. As a result, the idea of wireless electrical energy was developed utilizing a parabolic antenna and its fundamental method is the application of electromagnetic field induction procedures involving two solenoids-shaped copper coils. In this study the input voltage on the sender was 11.8 DC volts and a current of 1.92 amperes and the best efficiency was 2.609% in the calculation of loaded without a satellite dish at a distance of 1 cm. Based on test findings, it can be determined that power and efficiency are produced more when the winding distance is closer and less when the winding distance is farther.</em></p> Azhar Yusli Setiyono Copyright (c) 2024 ENERGI & KELISTRIKAN 2024-09-12 2024-09-12 16 1 1 11 Kontibusi Percepatan Net Zero Emission Dengan Pendekatan Strategis Peningkatan Efisiensi Pengelolaan Pembangkit Listrik Melalui Keunggulan Operasional http://jurnal.itpln.ac.id/energi/article/view/2517 <p><strong><em><span data-contrast="auto">ABSTRACT</span></em></strong><strong><span data-contrast="auto">&nbsp;</span></strong><span data-ccp-props="{&quot;201341983&quot;:0,&quot;335551550&quot;:2,&quot;335551620&quot;:2,&quot;335559740&quot;:240}">&nbsp;</span></p> <p><em><span data-contrast="auto">Net Zero Emission (NZE) has become a global agreement that is binding on every country throughout the world.

The research refers to the unbalance voltage repair work program for power quality in Building B e. Analyze and identify problems in the form of risk management. The phenomenon of voltage imbalance is often caused by turning on loads that require a large quantity of current supply.Using the Matlab simulation, it is found that there is still a high imbalance value due to the high reactive power value in Building B. To be able to plan treatment, understanding the scope of the risk and identifying it is the best way. Risk vulnerabilities exist in policy making, regulations, organizational management and operations. Actions taken to reduce the problem In terms of risk assessment, this is with proper treatment and gradual prevention. A PVUR value of 48.4% must at least be immediately diagnosed. However, there is still a need for more comprehensive follow-up action to look at performance for daily activities apart from simulations. </em></p> Sandi Budi Kurniawan Munir Fasihu Copyright (c) 2024 ENERGI & KELISTRIKAN 2024-09-12 2024-09-12 16 1 21 30 Pemanfaatan Limbah Oli Trafo Guna Optimalisasi Maintenance Trafo Dengan Konsep Circular Economy Melalui Proses Purifikasi Di PLN UP3 Bali Utara http://jurnal.itpln.ac.id/energi/article/view/2440 <p><em>Pemeliharaan adalah kegiatan rutin yang dilakukan untuk menjaga kondisi peralatan distribusi ketenagalistrikan salah satunya adalah unit transformator 20 kV agar dapat dipergunakan sesuai dengan fungsi dan kapasitas yang sebenarnya secara efisien. Hal utama yang diperhatikan dalam pemeliharaan trafo adalah kualitas oli sebagai pendingin dan isolasi trafo distribusi. Dimana dalam pemeliharaanya, akan dilakukan penambahan oli baru pada kuantitas tertentu yang dibutuhkan untuk mengisi volume trafo menggantikan oli yang hilang akibat penguapan saat proses operasi maupun akibat kebocoran trafo. Berdasarkan data historikal pemeliharaan trafo di tahun 2021 dan 2022 di UP3 Bali Utara, jumlah oli yang dipurifikasi dari 82 unit trafo sebanyak 20.555 liter dengan jumlah penambahan oli baru sebanyak 608 liter. Di sisi lain, terdapat limbah oli trafo bekas dari trafo dengan kategori rusak yang dikelola dengan proses penyimpanan sementara pada Gudang, selanjutnya dijual ke pihak ketiga dengan harga relatif rendah. artikel ini menjelaskan bagaimana perubahan dilakukan terhadap proses eksisting yaitu menghubungkan kebutuhan akan oli baru sebagai penambahan dan pemanfaatan limbah oli bekas di Gudang sebagaimana konsep circular economy. Hal ini dapat menghemat biaya treatment trafo, memberikan nilai tambah limbah oli dan mendorong pemanfaatan limbah secara komperhensif, serta secara tidak langsung dapat menekan angka dari kerusakan trafo jika dilakukan secara simultan.</em></p> Salim Afif - Abdul Syakur pawenary Copyright (c) 2024 ENERGI & KELISTRIKAN 2024-09-12 2024-09-12 16 1 31 45 Rancang Bangun Mesin Konversi Energi Bertingkat http://jurnal.itpln.ac.id/energi/article/view/1847 <p><em>Mesin konversi energi merupakan mesin yang merubah suata energi menjadi energi yang lain.

Sebagai langkah awal dalam menyelesaikan masalah rangkaian listrik untuk mendapatkan nilai arus digunakan Hukum Ohm serta Hukum Kirchoff arus dan Hukum Khirchoff tegangan. Kemudian, diubah ke dalam bentuk Sistem Persamaan Linier (SPL) dan menggunakan metode numerik untuk dihitung. Tujuan penelitian ini menggunakan persamaan dari rangkaian listrik 5-loop dengan 5 persamaan linier simultan matriks ordo 5x5, yang seluruh persamaanya tersebut akan diselesaikan khususnya menggunakan beberapa metode yang ada pada penelitian ini untuk menentukan nilai arus paling akurat dan error paling kecil. Digunakan sebanyak empat metode pada penelitian ini diantaranya metode Gauss, metode Gauss Jordan, metode iterasi Jacobi dan metode iterasi Gauss Seidel. Berdasarkan hasil error masing-masing metode pada penelitian ini menggunakan Root Mean Square Error (RMSE) didapat error pada metode Gauss sebesar 0,02473, error Gauss Jordan 0,02473, error iterasi Jacobi 0,00099 dan error Gauss Seidel 0,00153. Dapat dinyatakan dari perbandingan tersebut bahwa metode iterasi Jacobi adalah metode yang paling akurat dengan hasil error terkecil dibandingkan dengan rata-rata error pada metode lain. Sehingga, dalam menyelesaikan permasalahan nilai arus yang paling efisien ialah menggunakan metode iterasi Jacobi karena akurasinya yang lebih unggul dibandingkan dengan beberapa metode numerik yang digunakan&nbsp; pada penelitian ini.</span></em></div> Miftahul Fikri Copyright (c) 2024 ENERGI & KELISTRIKAN 2024-09-12 2024-09-12 16 1 53 62 Pola Kesesuaian Penggunaan Lampu Terhadap Intensitas Cahaya Dengan Metode Regresi Linier http://jurnal.itpln.ac.id/energi/article/view/2463 <p>The need for light intensity is one very important aspect in the room, because if the need for light intensity in the room is not in accordance with predetermined standards it will cause problems and have a bad impact on eye sight and is not good for the surrounding environment based on the provisions of SNI 03 - 6575 Year 2001. Researchers conducted research on the study of light intensity using the linear regression method in 40 residential homes to be able to find out how many percent of residential homes that are in accordance with the needs of light intensity based on standards at the time before and after regression and can determine the percentage of savings from energy use (kWh) lamps with linear regression method. It can be obtained from 40 samples of houses the results of measurement data before being regressed that the need for light intensity that is in accordance with the standard is only 1 house or 2,5%, while for the need for light intensity that is in accordance with the standard after being regressed in all rooms there is an increase to 21 houses or 52,5%. From the calculation results, the percentage of savings in the use of electrical energy after being regressed with the existing type of lamp is 14.8% or the energy is more efficient 3,492 kWh.</p> Satrio Yudho Ochtanisa Lailatus Sa’dyah Tony Koerniawan Copyright (c) 2024 ENERGI & KELISTRIKAN 2024-09-12 2024-09-12 16 1 63 73
