Abstract

Isolator berperan penting dalam menjaga kestabilan dan keandalan sistem jaringan listrik. Pada kondisi lapangan kontaminasi polutan seperti asap kendaraan pada permukaan isolator dapat mengurangi kekuatan dielektrik dan meningkatkan resiko terjadinya flashover pada isolator, terlebih kondisi basah memperburuk kondisi ini. Karena itu, penelitian ini dilakukan untuk menganalisis pengaruh kontaminasi dan variasi massa polutan asap kendaraan terhadap tegangan flashover isolator. Isolator yang digunakan adalah isolator porselen jenis pasak, dengan polutan berupa jelaga asap kendaraan yang diambil dari knalpot sepeda motor dan variasi massa polutan yang diuji adalah 1, 2, 3, 5, 7, dan 9 g. Proses kontaminasi isolator oleh polutan menggunakan standar IEC 60815-1, dilakukan dengan cara mencampurkan polutan dan 50 ml air aquades lalu mengoleskannya pada permukaan isolator secara merata menggunakan kuas. Pengujian tegangan flashover dilakukan pada kondisi isolator basah dan kering menggunakan tegangan tinggi AC melalui metode Slow Rate of Rise Test. Isolator porselen bersih memiliki tegangan flashover 79,49 kV kondisi kering dan 58,84 kV kondisi basah, setelah dikontaminasi tegangan flashover menurun seiring dengan penambahan massa ploutan hingga mencapai 48,69 kV kondisi kering dan 28,54 kV kondisi basah pada massa polutan 9 g. Penelitian ini juga mengukur NSDD (Non-Soluble Deposit Density) untuk mengetahui tingkat deposit polutan pada isolator. Nilai NSDD meningkat seiring dengan penambahan massa polutan, mulai dari 0,6 mg/cm² untuk 1 g polutan hingga 5,53 mg/cm² untuk 9 g, yang berkontribusi pada penurunan tegangan flashover dan performa isolator porselen.

Abstract

This community service program was conducted in 2025 with the Taruna Tani Sukamandiri Farmers’ Group in Ciamis Regency to address water scarcity and high fuel dependency in rainfed farming. An automatic solar-powered water pump system was introduced to strengthen energy independence, reduce irrigation costs, and increase the productivity of chili and cucumber crops. The program was implemented through five stages: coordination, technology installation, training, mentoring and evaluation, and ensuring sustainability. Results showed a significant reduction in diesel pump usage, cutting operational costs by IDR 1–1.5 million per season. Irrigation efficiency improved crop yields during the first two harvests, although the third harvest declined due to excessive rainfall. Farmers actively participated in installation, training, and maintenance, while students gained valuable hands-on learning. Academic outputs include a submitted journal article and a draft technical manual being processed for intellectual property rights, making this program a replicable model of sustainable agriculture.

Abstract

The increasing demand for electrical energy, along with economic growth and regional development, requires power systems to have a high level of reliability. One of the common problems in power systems is the overload condition on power transformers, particularly during load transfers caused by faults or network maneuvers. If left unaddressed, overload conditions can cause excessive temperature rise, accelerate insulation degradation, and potentially lead to widespread blackouts. Therefore, a protection scheme in the form of overload shedding is necessary to maintain system continuity and reliability. This research aims to analyze overload shedding scenarios during load transfers at the 150 kV Cilawu Substation. The analysis was conducted to determine the condition of the power transformer under normal conditions, during fault conditions, and throughout the manual overload shedding process based on a load selection scheme. The research methods used include literature study, substation system data collection, network modeling, as well as load and load shedding simulations using ETAP 19.0.1 software and script-based MATLAB. The analysis focuses on static loading conditions without discussing transient effects and dynamic system stability. The results show that the implementation of the overload shedding scheme is capable of reducing the power transformer loading to within safe limits, thereby preventing transformer tripping and wider blackouts. Furthermore, proper load selection during the load shedding process plays a crucial role in maintaining the electricity supply to priority loads. Thus, the overload shedding scheme can be utilized as an operational strategy to improve power system reliability at the 150 kV Cilawu Substation.
