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

The use of fossil fuels has resulted in the emission of greenhouse gases which can trigger global warming. In addition, fossil energy reserves that continue to decrease also raise concerns regarding aspects of their reselience and sustainability. Therefore, new and renewble energy must be developed immediately. The use of biomass as an alternative fuel for Steam Power Plant (PLTU) is in line with Indonesia’s efforts towards net zero emission in the future. In addition to increasing the contribution of renewable energy to the national energy mix, cofiring will also have a positive impact on the development of the circular economy as it can open up employment and business opportunities in the biomass sector, especially those based on garbage and waste. This research aims to determine the value of moisture content, heating value, combustion rate, and electrical energy produced from bamboo twigs and coconut shell waste with different composition variation. The method used in this research is an experimental method in which a bomb calorimeter is used to determine the heating, and a biomass stove is used to determine the combustion rate. The research finding reveals that the best samples for utilizing bamboo and coconut shell waste in the production of bio-briquettes as an alternative energy source are the variety of 200 grams of shell charcoal and 10 grams sago adhesive (sample 9). It is the best sample due to it has moisture content value of 6.38%, heating value of 5663.9 cal/gram, combustion rate is 0.227 gram/minute, and the electrical energy generated by converting the heating value to kWh is 6.5857 kWh/gram. In reference to SNI 01-6235-2000, the moisture content should not be more than 8%, and the minimum heating value is 5000 cal/g.

Abstract

This study examines the performance comparison of silicon and perovskite as semiconductor materials in photovoltaic solar cell technology. Silicon is known for its long-term stability, consistent power conversion efficiency, and well-established manufacturing infrastructure. However, its high-temperature, energy-intensive production process raises concerns about cost and environmental impact. In contrast, perovskite offers high power conversion efficiency, tunable material structure, and low-temperature fabrication, but faces major challenges in environmental stability and lead-related toxicity. A literature-based approach was applied, analyzing experimental and simulation data to evaluate key parameters such as energy bandgap, efficiency, carrier mobility, and thermal durability. The analysis indicates that combining both materials in tandem configurations presents a promising strategy for developing more efficient, flexible, and environmentally friendly photovoltaic systems

Abstract

Tegangan tembus merupakan salah satu parameter penting dalam sistem isolasi listrik yang menentukan batas kemampuan suatu medium dalam menahan medan listrik sebelum terjadi pelepasan muatan listrik (breakdown). Material elektroda yang digunakan dalam sistem bertegangan tinggi sangat mempengaruhi distribusi medan listrik dan nilai tegangan tembus yang dihasilkan. Oleh karena itu, penelitian ini dilakukan untuk mengkaji karakteristik tegangan tembus dari berbagai jenis material elektroda dalam medan listrik seragam. Studi ini secara khusus membandingkan empat jenis logam, yaitu stainless steel, aluminium, tembaga, dan kuningan, yang umum digunakan dalam aplikasi kelistrikan. Pengujian dilakukan secara eksperimental di Laboratorium Tegangan Tinggi dengan menggunakan konfigurasi elektroda bola-bola, jarum-jarum, dan pelat-pelat pada medium udara. Hasil pengujian menunjukkan bahwa material elektroda memiliki pengaruh signifikan terhadap besar tegangan tembus. Stainless steel secara konsisten menunjukkan performa terbaik dengan nilai tegangan tembus tertinggi pada semua konfigurasi, yakni 8,07 kV (bola-bola), 8,21 kV (jarum-jarum), dan 6,37 kV (pelat-pelat). Sebaliknya, tembaga menghasilkan tegangan tembus terendah, khususnya pada konfigurasi pelat-pelat sebesar 3,27 kV. Aluminium dan kuningan menunjukkan hasil yang bervariasi, namun masih di bawah performa stainless steel

Abstract

Electrical insulators are vital components in power transmission and distribution systems. The performance of insulators is significantly influenced by environmental conditions, including humidity, pollution, and temperature, as well as their material composition. This study reviews several recent scientific publications related to the performance of ceramic, polymer, and composite insulators under various environmental conditions. The analysis indicates that environmental contamination significantly reduces insulator performance, whereas industrial and agricultural waste-based materials, such as rice husk ash (RHA) and fly ash, offer considerable potential as innovative, environmentally friendly solutions. Experimental and simulation methods play a crucial role in understanding the electrical characteristics of insulators.
