Dye Sensitized Solar Cells (DSSC) are a low-cost solar cell technology with potential for development using environmentally friendly materials. This study develops a natural electrolyte from a mixture of tomato and bilimbi (ratios from 100:0 to 0:100) with the addition of 10% NaCl, and uses suji leaf extract as the dye. UV-Vis results show a maximum absorption at 679 nm (0.633 Abs), indicating …

SISTEM PENDINGIN PASIF BERBASIS PHASE CHANGE MATERIAL (PCM) PARAFIN DAN PARAF…

The utilization of solar energy continues to grow in line with the increasing demand for electricity. Solar panels convert solar radiation into electrical energy; however, an increase in surface temperature reduces their performance and efficiency. One approach to overcome this issue is the use of a passive cooling system based on Phase Change Material (PCM). This study investigates the effect …

ANALISIS PERBANDINGAN EFEKTIVITAS CAMPURAN SERAT BATANG PISANG DAN AMPAS TEBU…

The efficiency of solar panels is greatly influenced by the amount of solar radiation absorbed, but their performance often declines due to rising surface temperatures. As a solution, the use of organic materials as passive coolants holds great potential for maintaining temperature stability. Banana stems and sugarcane bagasse were selected for their chemical properties that support thermal man…

A thermoelectric generator is a semiconductor device that can generate electrical energy from thermal energy. This study examines the performance of a thermoelectric generator with the addition of a magnifying glass configuration and a copper plate on the hot side, as well as variations in the cooling system, either without a cooling system or using a paraffin wax–based phase change material …

PERANCANGAN SISTEM PROTEKSI INTERNAL PADA PEMBANGKIT LISTRIK TENAGA SURYA

Solar energy is one of the new renewable energy that can be utilized as a source of electricity generation using solar panel technology. Indonesia has a large solar radiation potential of 4.8 kWh/m2 /day, so it is possible to develop the use of solar as an alternative energy to reduce the use of fossil energy which is limited and has many negative impacts that can damage the earth. This researc…

PERANCANGAN SISTEM PROTEKSI EKSTERNAL PADA PEMBANGKIT LISTRIK TENAGA SURYA

Indonesia, as a tropical country with high lightning intensity, requires an effective external lightning protection system for large-scale solar power plants to ensure operational continuity. This research designs an external lightning protection system for a 63-hectare solar power plant in Tanjung Pasir using IEC 62305 standard with Rolling Sphere Method approach at protection level III (45-me…
