Abstract

Sistem distribusi Jaringan Tegangan Rendah (JTR) yaitu bagian dari distribusi tenaga listrik yang menghubungkan antara transformator distribusi dengan Sambungan Rumah (SR) yang merupakan titik akhir dari pelayanan listrik kepada konsumen. Sehingga potret pelayanan dapat dilihat dari mutu tegangan dan tingkat keandalan dari sisi sambungan rumah. Jumlah tarikan sambungan rumah (SR) deret yang tidak sesuai standar akan berpengaruh terhadap kehandalan yang merupakan kerugian bagi PLN yang mengakibatkan drop voltage ( tegangan jatuh). Metode yang digunakan pada proyek akhir yaitu dengan melakukan studi literatur dan survei lapangan dengan pengamatan langsung dan mengukur hasilnya. Hasil yang diperoleh dari survei lapangan dan analisa perhitungan tegangan jatuh pada pelanggan pertama SR Tipe Deret pada Gardu JPR 047 Penyulang Merak mencapai 214 volt dengan persentase tegangan jatuh 4,44% nilai tersebut menujukan bahwa pelanggan pertama SR tipe Deret masih sesuai standar jatuh tengangan. Tegangan jatuh pada pelanggan tarikan ke-5 SR Deret mencapai 194 volt dengan persentase tegangan jatuh 12,22% nilai tersebut menujukan bahwa pelanggan ke-5 SR tipe Deret sudah tidak sesuai standar jatuh tengangan. Sementara untuk tegangan jatuh pada pelanggan tarikan ke-20 SR Deret mencapai 167 volt dengan persentase tegangan jatuh 26,11% nilai tersebut menujukan bahwa pelanggan ke-20 SR tipe Deret sudah sangat drop dan tidak sesuai standar jatuh tengangan. Kata Kunci: JTR(Jaringan Tegangan Rendah), SR Deret, Drop Tegangan, Persentase Tegangan jatuh

Abstract

Protection systems are security mechanisms designed to safeguard electrical equipment from technical malfunctions, natural disturbances, operational errors, and other causes. These systems serve as electrical safety measures in power systems installed in power distribution networks, power transformers, electric power transmission lines, and generators, all of which protect the electrical system from faults or overloads. This research aimed to determine the short-circuit current and the overcurrent relay settings for the Nuri feeder at PLTD Yarmork. The method employed in this study involved collecting primary data directly from the field through observation and load measurements on transformers and distribution network lengths, followed by manual calculations. The research findings indicated that the maximum short-circuit current resulting from a three-phase fault at a fault location of 0% along the feeder was 6978.448 A, while the minimum current at 100% was 2313.838 A. For two-phase faults, the maximum short-circuit current at 0% feeder length was 976043.513 A, and the minimum current at 100% feeder length was 2003.842 A. The calculated TMS settings were 0.147 for the outgoing side of the OCR and 0.270 for the incoming side. Overall, the computed settings for both the overcurrent and earth fault relays were aligned with the field settings.

Abstract

Access to clean water is a fundamental necessity that underpins effective public health services and the operational efficiency of health facilities, including the Bonggo Health Center in Sarmi Regency. Recognizing the importance of reliable clean water access, a community assistance initiative was launched to establish a sustainable water installation system at the Bonggo Health Center. This initiative is crucial to enhancing the health center’s ability to deliver quality healthcare services, as safe, clean water is essential for various healthcare functions, from sanitation to patient care. The primary aim of the assistance program is to equip the Bonggo Health Center with a dependable source of clean water, ensuring it meets health and safety standards for use in medical services. To achieve this goal, the implementation method was carefully structured, involving several sequential steps. First, the service team conducted a comprehensive location survey to assess the water requirements and potential challenges. Following this, the team engaged in in-depth problem discussions, planning sessions, and preparatory work to lay the groundwork for the installation. The actual construction of the water installation was then carried out, followed by rigorous testing and evaluation to ensure functionality and quality. Through close collaboration with the Armopa Village community, the service team successfully completed a fully operational clean water installation. This unit now provides a reliable supply of high-quality water for the Bonggo Health Center, significantly improving the center’s capacity to serve the healthcare needs of the surrounding community. This installation not only meets immediate needs but also sets a foundation for sustained health service enhancements and community well-being in the region.

Abstract

This community service activity aims to introduce biomass stoves to communities in need, particularly those with abundant biomass waste. The biomass stove's performance has already been evaluated through prior research conducted on campus. This community service initiative will be carried out with the Berkat Rama farmer group in Bibiosi Village, a major corn production area near Cenderawasih University in Arso District, Keerom Regency. Based on preliminary site assessments, local farmers reported significant quantities of agricultural waste, specifically corn cobs, left after harvest. This waste has not been optimally utilized by farmers and is typically disposed of by burning. Motivated by this, our community service team from the Department of Mechanical Engineering at Cenderawasih University aims to introduce corn cob-fueled biomass stoves to the local community. The Community Service Program (PKM) was met with strong enthusiasm from participants, who actively engaged in the socialization session through to its conclusion. The community expressed a desire for more frequent activities of this kind to broaden their knowledge and skills, especially regarding appropriate technology applications. The final outcome of this community service is an increase in both knowledge and skills among members of the Berkat Rama farmer group, specifically in the fabrication and operation of the introduced biomass stoves. They also received training in operational safety for biomass stoves. The acquired knowledge and skills are expected to be applied and shared with other community members and farmers in the area.
