Pengaruh Penggunaan Lapisan Phase Change Material Parafin Grafit Sebagai Pendingin Terhadap Efisiensi Panel Surya Polycrystalline
Get PDFSolar panels such as PLTS can be an alternative to complete electricity needs. However, the intensity and temperature of the sun that can not be adjusted are an obstacle to the use of solar panels. Continuous absorption of sunlight can cause solar panels to overheat. Therefore, it is necessary to cool the solar panels, therefore the heat absorbed does not exceed the capacity. Phase Change Material (PCM) paraffin graphite is one of the coolants for solar panels. PCM paraffin graphite was used to coat solar panels and then measured for voltage, current, and temperature. The results were compared with solar panels that were not covered with PCM paraffin graphite. The test results found that solar panels coated with PCM produced a lower surface temperature of 0.1458% than those without PCM. Meanwhile, the efficiency and power produced by PCM-coated solar panels were 19.496% and 0.02685% higher than solar panels without PCM, respectively, so the use of PCM paraffin graphite in solar panels can increase their efficiency.Panel surya sebagai PLTS dapat menjadi salah satu alternatif untuk memenuhi kebutuhan listrik.

Rancang Bangun Pembangkit Listrik Tenaga Gelombang Laut Menggunakan Sistem Oscillating Water Column
Get PDFOcean wave power plant is one of the plants that uses sea waves as the main energy. Although the amount of energy is abundant, in Indonesia the use of sea waves as electricity generators is still small. This is due to the lack of human resources to manage the wave energy of sea water. Many research studies on the Oscillating Water Column have been carried out, but it is only limited to a potential or feasibility study to be installed on the coast. Therefore, the focus of this research is to design a sea wave power plant with an oscillating water column system. The working process of the tool begins by adjusting the pwm to drive the motor power window which is connected to the wave arm. When the wave arm moves back and forth, it will produce artificial ocean waves. Artificial waves in the chamber produce compressed air, the air produced is used to rotate the turbine blades that have been connected to the generator to produce electrical energy. The greatest voltage and current is obtained when the wind speed reaches 7.7 m / s and the largest pulley rotating speed reaches 31,9 rpm at the 17 cm water level, which is 3.03 V DC and 6,07 mA. The test results prove that the potential of water waves can be used to generate electricity The development of the capacity of ocean wave power plants can be done by changing the dimensions of the turbines and increasing the capacity of the generator
