Abstract

Salah satu masalah dalam penggunaan resin epoxy sebagai bahan dasar pembuatan isolator adalah harga resin epoksi yang masih relatif mahal dan susah didapatkan khususnya di daerah Gorontalo. Penelitian kali ini mencoba menambahkan pasir sungai Bolango Gorontalo dan pasir silika sebagai pengisi (filler) ke dalam bahan resin epoxy dengan variasi atau komposisi tertentu untuk kemudian dilakukan pengujian terhadap tegangan tembus dan kuat tekan. Metode experimen digunakan pada penelitian ini, yakni pengujian tegangan tembus menggunakan sumber tegangan tinggi AC dan pengujian kuat tekan menggunakan alat uji kuat tekan. Dari hasil penelitian didapatkan bahwa, isolator resin epoxy dengan penambahan pasir sungai sebagai filler memiliki ketahanan terhadap tegangan tembus yang kurang baik dibandingkan dengan isolator resin epoxy dengan filler berupa pasir silika. Namun, dari aspek kuat tekan, maka isolator resin epoxy dengan filler berupa pasir sungai memiliki nilai kuat tekan yang lebih tinggi dibandingkan dengan isolator resin epoxy dengan filler pasir silika.

Abstract

Solar panels are a semiconductor component that is capable of converting solar energy into electrical energy through the photovoltaic principle. Fluctuations greatly influence the electrical energy produced by solar panels in surface temperature. Therefore, this research aims to assess the impact of solar panel surface temperature and compare the power produced by two types of solar panels, namely polycrystalline and monocrystalline panels. The method used in this research is direct measurement using a temperature measurement device with an infrared thermometer and a solar power meter. The results of measurements and analysis show that the higher the surface temperature of the solar panel, the less power produced will decrease. In addition, in a comparison of the output power between polycrystal and monocrystal-type solar panels, it was found that the power of the monocrystal type was higher than the polycrystal type.

Abstract

This research was conducted to test the reliability of the performance of the OCR-GFR relay whether it complies with the settings or not during field testing and to find out a comparative analysis of the performance of theoretical calculations with the results of field testing using the CMC 356 test equipment. This research uses a descriptive method. This research aims to determine whether the performance of the OCR–GFR relay that is being used is still good performance or suitable for use. And the tests carried out are pick up and drop off tests and characteristic tests. The results of the OCR pick-up and drop-off relay test were 1.2 A and the drop-off was 1.134 A. Meanwhile, for the GFR relay the pickup relay was 0.20 A and the drop-off was 185.0 mA. The results of the pickup and drop-off tests can conclude that the relay works according to its settings. Meanwhile, for field testing, the OCR relay characteristics at 1.5 times the setting current are 3.627 s and the theoretical calculation results are 3.697 s. For the GFR relay, the field test results obtained were 1.5 times the setting current, namely 1.981 s, and the theoretical calculation results were 1.977 s. This means that the test results are close to the calculated values. This shows that the Micom P142 OCR/GFR Relay tested is still in good performance.

Abstract

One of the important factors and main indicators of the quality of electricity supply services from the system to customers is the reliability of the distribution network. Frequent disruptions to the distribution network can reduce the reliability of electricity distribution. Based on data obtained from PLN UP3 Gorontalo, the BP1 feeder is a vulnerable area that experiences the most frequent service disruptions, with a total of 96 disruptions during 2023. This study aims to determine the reliability index value of the 20 kV distribution system for the BP1 feeder using the section technique, and to determine the undistributed energy and the losses incurred due to blackouts in the BP1 feeder. The method used in this study is the section technique, which evaluates a distribution system by assessing how the failure of a piece of equipment affects its operation. The results of the study show that the reliability index for the BP1 feeder in 2023 is SAIFI of 15.43 times/customer/year, SAIDI of 3.61 hours/customer/year, and CAIDI of 0.23 hours/customer. From these results, it can be concluded that the SAIFI value for the BP1 feeder is not yet reliable, as it does not meet the SPLN 68-2:1986 standard of 3.2 times/year. Meanwhile, the SAIDI value of the BP1 feeder is reliable because it meets the SPLN 68-2:1986 standard value of 21.09 hours/year. The unsupplied energy (ENS) is 18,809.81 kWh, so the loss value for the BP1 feeder in 2023 is Rp. 30,933,106.55.

Abstract

Indonesia's rising energy needs push the adoption of solar energy to reduce fossil fuel use. This study analyzes how sunlight's incident angle affects the output power of polycrystalline solar panels. It also determines the optimal angle for efficiency. A quantitative experiment used two panel setups: a mobile panel set at 90° and a fixed panel that tracked natural angle changes (07:00–17:00 WITA). Over seven days in Gorontalo, voltage, current, power, light intensity, panel temperature, air temperature, and humidity were measured. Results showed that the incident angle greatly influenced output power. The mobile panel produced a maximum power of 8.13 W at an intensity of 8.7846 W/m2 (09:30). The fixed panel peaked at 6.76 W at a 69° angle (12:00). For the fixed panel, the optimal angle ranged from 50° to 70°. Efficiency dropped when panel temperature exceeded 50 °C. In general, mobile panels provided higher and more stable performance. This highlights the value of a solar tracking system or determining the optimal angle to boost efficiency and support national energy security.
