Abstract

Energi terbarukan merupakan energi alternatif untuk mengatasi permasalahan yang timbul pada energi konvensional, yaitu terbatas dan menimbulkan polusi yang dapat merusak lingkungan. Disisi lain, Indonesia sebagai negara tropis yang terletak di kawasan katulistiwa, memiliki potensi energi matahari yang melimpah dan bersinar sepanjang tahun. LAPAN mencatat radiasi harian rata-rata energi surya adalah 4.8 KWh/m2. Karenanya, sistem pembangkit listrik tenaga surya (PLTS) memiliki potensi yang sangat besar sebagai sumber energi utama untuk digunakan di Indonesia pada masa depan. Salah satu permasalahan utama saat perencanaan PLTS adalah ketidakpastian cuaca, hal ini menyebabkan kesulitan dalam merencanakan kapasitas PLTS yang dibutuhkan. Permasalahan ini dapat terselesaikan jika ketidakpastian cuaca ini dapat diatasi. Metode yang dapat diandalkan untuk mengatasi ketidakpastian ini adalah pemodelan stokastik, hali ini dikarenakan pemodelan stokastik merupakan suatu model yang dibangun menggunakan aturan-aturan peluang. Model hidden Markov (MHM) merupakan salah satu pemodelan stokastik yang dapat diandalkan tanpa harus mengetahui faktor-faktor penyebab permasalahan yang dimodelkan, termasuk permasalahan pada cuaca ini yang mana faktor-faktor penyebabnya sulit diamati. Ditengah keterbatasan, pemodelan ini menggunakan data cuaca harian BMKG pada wilayah Samarinda, Kalimantan Timur pada tanggal 1 Juli sampai dengan 31 Oktober 2019 (sebanyak 123 hari). Data cuaca yang diperoleh tersebut dikelompokkan menjadi empat kategori, yaitu cerah, cerah-berawan, berawan, hujan. Model dibuat menggunakan data cuaca sebanyak 105 hari, yang mana sisa sebanyak 18 hari digunakan untuk mengecek ketepatan prediksi model. Hasil penelitian menunjukkan bahwa model memiliki ketepatan sebanyak 87 dari 105 hari (82,86%). Adapun keatepatan model untuk memprediksi sebanyak 13 dari 18 hari (72,67%).

Abstract

Audit Energi adalah tindakan pemeriksaan dan pengujian terhadap energi yang digunakan dalam suatu kegiatan untuk mendapatkan data pemakaian energi, sebagai bahan masukan dan saran berupa tindakan perbaikan dengan tujuan agar dapat dicapainya penggunaan energi secara efisien, dimana semaksimal mungkin output yang sama dapat diperoleh dengan menggunakan energi lebih sedikit, ataupun dengan mengurangi konsumsi dan kegiatan yang menggunakan energi. PLTU unit 5 PT. PJB Muara Karang yang telah beroperasi selama kurang lebih 35 tahun mengalami gap performance yang cukup signifikan terhadap commissioning (new and clean condition) sehingga diperlukan suatu upaya identifikasi untuk mempersempit gap performance tersebut.

Abstract

This research aims to design an automation system on Dump truck as fuel efficiency effort. The existence of control of fuel efficiency will be very helpful in reducing cost / budget expenditure on each company. Auto Economy mode is an automatic system in the mode of activation (power mode or economy mode) in accordance with the state of the unit load. When the unit is loaded heavy then the system will automatically turn on the power mode. And then, when the unit is not charged, the system will automatically activate the economy mode. Automatic operation of 2 modes would require an enhancement as a controller. In the Auto Economy mode HD785-7 used PLC as a controller.

Abstract

This community partnership program aims to help the public to know the security of residential installations and fire prevention efforts due to an electrical surge. As well as providing motivation to be able to continue to encourage and apply to the community in the partner area to always prevent fires due to electrical short circuit and use electrical equipment according to standards. With the partnership program activities of the community in the Gondrong neighborhood, Cipondoh Sub-district will be able to provide education on integrated electrical installations to avoid fire hazards due to electricity

Abstract

Photovoltaic systems or solar power plants convert electromagnetic energy from sunlight into electrical energy. This renewable energy based power plant is one of the recommended solutions for electricity in remote rural areas where sunlight is abundant and fuel is difficult to obtain and relatively expensive. The Ministry of Energy and Mineral Resources has issued Ministerial Regulation regarding the use of the Roof Solar Power Plant system by consumers of the Indonesian Electricity Company (PLN). It is hoped that with this regulation the solar panel business and industry can flourish. The method we use in this Community Service is the observation method. By making observations in the field accompanied by interviews with the surrounding population becomes our primary data source in determining the needs of the problems that occur. In Cilatak Village we found minimal of street lighting, and limited electricity supply, for this reason we strongly support programs for new and renewable energy for remote areas that are difficult to get electricity supply. Based on this, we created the Development of Public Street Lights with Solar Electricity in Cilatak Village, Ciomas District, Serang District, Banten, so that the problems of public road lighting can be overcome, and we educated the utilization and maintenance.

Abstract

The problem in the tropics is the effect of temperature changes on the high voltage system, resulting in isolation around the electricity distribution in the 20 kV cubicle, which can trigger the insulation failure (breakdown voltages) on a feeder. To reduce the occurrence of power outages due to insulation failure with changing temperatures, direct testing is carried out by providing temperature variations ranging from 30oC to 90oC. To correctly understand the phenomenon, testing should be carried out. The test is carried out every 5 oC temperature increase. Based on the research results, a graph is obtained that explains the decrease in the breakdown value at 50oC, which causes the insulation breakdown voltage to be 27kV, and the decrease in the breakdown voltage at 90oC, which causes the insulation breakdown voltage to decrease to 22kV. Based on experiments, it can be concluded that the greater the temperature rise, The breakdown voltage appears more quickly. Thereafter, the data from the research results were tested using the linear regression analysis method, so that a MAPE obtained 3.89% and an RMSE obtained 1.33 were obtained with an average percentage obtained 0.37%.
