Abstract

A generator is a device or engine that generates electrical energy from the presence of mechanical energy obtained from a prime mover in the form of a diesel engine as the prime mover which then drives an AC generator or alternator, causing an electrical voltage. The aim of this research is that the generator can supply electricity needs at the Sumur Welut site by changing or modifying diameter of the wire on the alternator. This analysis includes the Stator and Rotor on the Alternator generator so that it can produce the electricity needed. From the test results, the load generated after being modified can supply power at the site but the fuel consumption is more wasteful, namely 0.9 liters / minute and also the generator temperature increases to 88.2 C. So that the radiator planning is done by changing the surface area of ​​the radiator from 2915 cm2 to 8077 cm2. Or change the radiator fan, which originally changed the wind speed of 4.7 m / s to 13 m / s. Keywords: Generator, Alternator, Load Testing, Radiator, Cost.

Abstract

Indonesia is a tropical country, which gets a lot of sunshine every year. Harvesting energy from solar heat is an alternative solution to obtain renewable and environmentally friendly electrical energy. The purpose of this research is to design and test the temperature and flow of the working fluid of a solar collector for energy harvesting. The method used is true experiment research by making a solar collector prototype. Measurement of the temperature and pressure of the working fluid is carried out by varying the power of the heating lamp as a substitute for sunlight in the test. The experimental results show that the greater the heat energy received by the solar collector, the higher the temperature of the working fluid and the resulting pressure during the same test. The highest temperature recorded for the liquid coming out of the solar collector reaches 63.6 oC with a maximum pressure difference of 19.6 Pascals. The results of this test will be followed by testing the flow rate of the working fluid to determine the power potential of the working fluid for harvesting energy. Highlights: Efficiency Enhancement: Optimizing solar collector design for increased heat energy absorption and efficient energy conversion. Temperature-Pressure Correlation: Investigating the relationship between heat energy, working fluid temperature, and pressure for better energy yield. Flow Rate Analysis: Assessing working fluid flow to gauge energy potential and inform effective energy harvesting strategies. Keywords: solar collector, temperature, fluid pressure, energy harvesting
