Abstract

Overheating is a failure mode that significantly affects the reliability of electronic devices. All electronic devices, including a 3-phase inverter driving a traction motor, produce heat dissipation. Heat dissipation needs to be controlled with cooling to prevent overheating. Overheating can be avoided by increasing cooling or reducing heat dissipation. Heat dissipation in the 3-phase inverter is caused by the internal resistance of the metal–oxide–semiconductor field-effect transistor (MOSFET), switching loss, and other factors. Cooling for the 3-phase inverter can use water coolant or air coolant. The cooling system is based on the amount of heat dissipation produced. Cooling of a 3-phase inverter can use air coolant with the addition of an extended surface area in the heat sink. The heat sink uses aluminum material, often called pin fin. There are kinds of aluminum available in the market. We calculated heat generation based on the MOSFET's internal resistance, switching loss, and other factors. We validated the simulation results experimentally using a thermal camera. Thus, we could find an optimal number, dimensions, and aluminum type of fin for the cooling system in the 3-phase inverter.

Abstract

A pyranometer is a device used to measure the level of solar irradiation. This device has a sensor that measures the density of the electromagnetic flux of solar radiation on a flat plane. The electromagnetic flux density parameter is converted into an electrical parameter in watts per square meter. Pyranometers are used in weather station devices to analyze and predict weather conditions. Solar power generation systems are usually also installed with this device. It is intended to monitor solar irradiation's condition to examine the generating system's performance. This article discusses the photovoltaic-based pyranometer characterization method. The characterization method is carried out to determine the measurement parameters such as accuracy, precision, and hysteresis. Knowing these parameters will make it possible to see the performance of measuring solar irradiation levels by a measuring instrument for solar irradiation levels, like a pyranometer. The characterization method is to compare the measurement results with standard instruments. The solar irradiance level monitoring is also optimal, accurate, and precise with a reliable measurement method.

Abstract

The freshwater fish farm, developed by the Maju Rukun community in Dusun Karang Ploso, Ngerong, has faced issues with slow fish growth and poor water quality after operating for seven months. These problems are caused by inadequate water circulation systems, resulting in a delayed growth process that normally takes only 3 to 4 months. The situation is exacerbated by poor drainage and high electricity consumption for a 0.5 HP (370 Watt) water pump. The water must be partially replaced with new water on a regular basis to maintain its quality. This procedure increases electricity consumption from the public grid or Perusahaan Listrik Negara (PLN) and raises operational costs by up to 80%, especially during the dry season. To address this issue, a community service project has been carried out to develop a 1.7 kWp hybrid Solar Power Plant. This system is designed to reduce reliance on PLN electricity and to provide additional energy for water circulation using solar panels and batteries. Additionally, this community service also includes training on how to operate and perform maintenance of the installed system for the Maju Rukun community and the locals. Implementing the hybrid power plant has significantly reduced electricity costs from PLN. Moreover, fish farm productivity has increased and contributed positively to the development of renewable energy technology in the fisheries sector.
