Abstract

The earthing system is a system that should be applied in substations. Its function is to protect both humans and equipments are located around the substation of the danger caused by electrical system fault. The fault that often occurs is short circuit to ground which can cause different voltage gradient between points around the substation. The earthing system is expected to overcome the problems occurred, so that in its design should follow applicable standards. The design of the earthing system at 150/20 kV substation refers to the IEEE Std 80-2000. In this paper, earthing system is designed based on the field datas are extracted from substation Garuda Sakti. Based on design verification, its obtained such as following result i.e. mesh voltage 626.38 V, step voltage 344.46 V, length of the conductor grid 2300 m with 0.55 ? resistance and the conductor achieved in this design able to cover area of 86, 59 mm2. Overall of design was complience to the IEEE Std 80-2000.Keywords - earthing system, substation, touch voltage, step voltage

Abstract

This community service activity aims to improve the efficiency of fish feeding management through the implementation of a Decision Support System (DSS) using the Simple Additive Weighting (SAW) method in Mariendal II Village. The main problem faced by fish farmers is the manual feeding process based on estimation, leading to inefficiency and suboptimal fish growth. The method used in this activity is a participatory approach consisting of socialization, training, technology implementation, and evaluation. The developed system considers several criteria, including fish biomass, age, population, water quality, feeding time, and feed type. The results show that participants experienced significant improvements in knowledge and skills in using the DSS. The system successfully provided optimal feeding recommendations and was integrated with an automatic feeder, resulting in more consistent and efficient feeding practices. This activity also increased farmers’ awareness of technology adoption in aquaculture. Overall, the implementation of DSS contributes to reducing feed waste, improving productivity, and supporting sustainable fish farming practices.
