Abstract

Installation of spotlights and LED strips with automatic operation at the entrance gate of the SPI Cluster RT.10 RW.04 Bandungrejosari Village, Sukun District Malang City is based on the absence of lighting contained in the writing of the Sukun Pondok Indah Cluster (SPI) so that many guests or couriers who are not aware of the housing. With the installation of spotlights and LED strips, it is hoped that the writing on the gate of the Sukun Pondok Indah cluster will be bright and visible so that guests or couriers can immediately know about the housing. Then people can see when installing spotlights and LED strips with automatic operation, they hope that people can install lighting installations automatically in their respective homes correctly and according to standards. Then people do not need to operate the ON / OFF spotlights and LED strip every day. That way, the benefits of installing spotlights and LED strips with automatic operation, people don't need to ON / OFF the lighting every time.

Abstract

This research is focused to help peoples in remote areas who do not have electricity supply from PLN, but have sources of water flow in rivers. The main objective of this research is to create a picohydro hydroelectric power plant with a floating turbine to utilize the kinetic energy of river water flow in areas that have not been supplied with PLN electricity. The flow of water in the river will rotate the turbine, which in the end the rotational power is channeled through a pulley and belt system, which eventually turns an alternator. The alternator used is a three-phase AC alternator. Then the AC current will be rectified by the bridge rectifier to then be used to charge the battery and go to the load. In addition, in this study, the ability of the pico-hydro system to supply electrical energy will be tested to be able to run 12 V DC electrical loads and charge 12 V batteries.

Abstract

Single-phase E-I transformers are widely used in power-conversion applications, including grid-connected flyback micro-inverters for solar photovoltaic systems, yet their performance often deteriorates due to high core loss and harmonic distortion generated by nonlinear loads. This study evaluated the effect of the annealing process on core loss, voltage regulation, energy efficiency, and voltage/current harmonic distortion of a single-phase E-I transformer under nonlinear loading. Three transformer samples were tested under no-load and nonlinear-load conditions (rectifier and inverter) before and after annealing at 180, 350, and 450 °C for 60 minutes, followed by harmonic-distortion measurement using a power logger on a flexible conveyor system and a single-phase induction motor. Annealing at 350 °C produced the most significant core-loss reduction, from 150.3 W to 110.6 W, while linear-load efficiency reached 97-98% and voltage regulation remained stable near 98%. Harmonic measurements showed voltage total harmonic distortion (THDv) of 5.8% on the flexible conveyor system and 5.6% on the induction motor without a variable speed drive, both below the 8% IEEE 519 limit, while individual current harmonic distortion (IHDi), current total harmonic distortion (THDi), and total demand distortion (TDD) also remained within the standard's safe margins. These findings indicate that medium-temperature annealing can improve the magnetic performance of the transformer core while keeping power quality within standard limits under nonlinear loading. The practical implication is that this annealing guideline can be adopted by small and medium-scale transformer manufacturers to improve energy efficiency without costly equipment investment.
