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.

Abstract

Small signal stability refers to the ability of a system to return to equilibrium after experiencing a small disturbance. In this research, the Kalimantan electricity system will be analyzed for the stability of its small signal. Analysis of the stability of small signals in electrical systems including local disturbances and inter-area disturbances. The Kalimantan system will be analyzed using Power Factory software. System analysis was carried out by evaluating the eigenvalues "‹"‹(real part and imaginary part), oscillation frequency (damped frequency and frequency ratio) produced in the Kalimantan 500 KV electricity analysis. In the analysis results, the Kalimantan system is categorized as stable as indicated by the real part and imaginary part values "‹"‹located on the negative side of the Cartesian coordinate curve. Then, analyzing small signals, there are 117 modes categorized as local mode and 4 modes categorized as inter area mode.
