Abstract

Renewable energy is an energy source that can be utilized continuously and is available by nature. One example of using renewable energy is photovoltaic. Photovoltaic is a tool used to absorb solar energy and convert it into electrical energy using the photovoltaic effect method. This research aims to monitor the salinity (salt content) of sea water by utilizing solar energy using the Buck Converter type DC to DC Converter method to regulate and reduce the higher voltage to a lower voltage to be loaded on the microcontroller as the reading output. This research was designed using a 20 WP photovoltaic with a maximum voltage of 20 volts which functions as a power supplier or energy source whose voltage is then reduced by a buck converter circuit to a smaller voltage of 5 volts to be charged to the Arduino Uno in processing salinity measurement data using a TDS sensor. as a measuring tool. The test results of the equipment show that the DC to DC Converter circuit is successful in reducing the photovoltaic voltage so that it can operate the microcontroller.

Abstract

One of the main components of wind power plants that can be developed is the Permanent Magnet Synchronous Generator (PMSG). In this research, PMSG design will be carried out using Finite element method software with Geometry Variations of Permanent Magnet Synchronous Generator with a combination of 12 8-pole slots which will then be modeled on Finite element method software. In one variation of this generator geometry has been successfully created with good efficiency. This model will argue for the specifications of variations 1, 2 and 3 and are analyzed by comparison test scenarios and loading with load R. The generator with a no-load test simulation produces between variations in variation 1 of 10.93 volts, variation 2 of 12.67 volts, variation 3 of 13.77 volts. When testing load with load resulted in an efficiency of variation 1 of 20.5%, variation 2 of 19.6%, and variation 3 of 33.4%.

Abstract

Sun is one of the new renewable energy sources that can be used as a source of electrical energy that is available on the earth. But the sun in nature has a light intensity that varies greatly with each time and place. This issue can be overcome by using the Modification Sepic Converter tool with a fuzzy method to produce a stable electrical voltage so that it becomes usable electrical energy. This tool uses a series of converters connected to photovoltaics. The tool also uses a voltage sensor as feedback for the Fuzzy method to maintain a voltage of 21-23VDC to 48VDC.
