Abstract

This research aims to optimize the performance of the voltage system at the Nagan Raya Steam Power Plant (PLTU) by installing capacitor banks. Capacitor banks are integrated into the system to increase voltage stability, reduce power losses, and increase energy efficiency in PLTUs. The research method involves analyzing the existing voltage system, designing the capacitor bank installation, and evaluating the system performance after installation. It is hoped that the results of this research can make a positive contribution in improving the performance of PLTU Nagan Raya and overall energy efficiency.

Abstract

This study was focused on the characterize the hibridisation of kenaf and sugar palm fibre in reinforcing the polypropylene matrix. Addition of MAPP (Maleic Anhydride Polypropylene) was used as compatibilizing agent with variation of 2%, 3% and 5%. The specimen materials were prepared with 30% amounts of fibres while the ratios between kenaf and sugar palm fibre are 10:20, 15:15 and 20:10. The composites were fabricated using melt mixer technique and followed by compression molding process. The specimens were cut according ASTM Standard D790 for conducting the flexural testing. After testing done, the results shown that flexural strength of composites tend to decreased when the content of MAPP increased. The ultimate flexural strength was attained at 2% MAPP addition of the hybrid composites with 20% kenaf fibres. Among the composites with different ratios, the hybrid composites that contain more kenaf fibres exhibit the higher value in flexural strength than the composites that contain more sugar palm fibres.

Abstract

This community service aims to improve care, maintenance and repair of submersible water pumps spread across Gampong Luthu Lamweu, Aceh Besar Regency, Aceh Province. Activities begin with the preparation stage, site feasibility survey, identification of problems with partners, implementation of activities, as well as socialization and evaluation of results. Problem identification is carried out through maintenance, upkeep and repair steps for water pumps, which are delivered through training and technical assistance by the PKM implementation team to participants, with the aim of ensuring that participants are able to independently manage and maintain the water pump system. The repair process focuses on components that can be repaired, while for damaged components, they are replaced with new spare parts. Evaluation is carried out at the final stage of activities to ensure that the water pump is functioning optimally and water distribution is running normally, so that the availability of water for agricultural and rice field needs can be guaranteed. This activity was carried out successfully, as evidenced by the appreciation received from the participants, especially local farmer groups, which showed their level of satisfaction and pride in their success in independently managing the maintenance and repair of water pumps.
