Abstract

Sistem distribusi tenaga listrik adalah bagian dari sistem tenaga listrik yang berfungsi menyalurkan listrik kepada konsumen. Analisa keandalan sistem proteksi meliputi koordinasi antar peralatan proteksi dalam jaringan distribusi yang harus memenuhi standard yang ada. Penelitian ini bertujuan untuk menganalisa besaran nilai setting dan karakteristik overcurrent relay (OCR) dan ground fault relay (GFR) di Gardu Induk 150 kV Buduran menggunakan aplikasi ETAP 19.0.1. Nilai setting OCR dan GFR ditentukan berdasarkan pada standard IEC 60255, relay yang terpasang pada GI 150 kV Buduran memiliki kurva karakteristik standard invers. Dari hasil penelitian diperoleh hasil bahwa besarnya arus gangguan hubung singkat dipengaruhi oleh jarak titik gangguan, semakin jauh lokasi gangguan maka arus gangguan hubung singkat akan semakin kecil, begitu pula sebaliknya. Waktu kerja relay di sisi outgoing lebih cepat dibandingkan sisi incoming dengan selisih waktu rata-rata sebesar 0,06 detik. Hal ini disebabkan lokasi gangguan mempengaruhi besar kecilnya selisih waktu. Semakin jauh jarak lokasi gangguan, maka semakin besar selisih waktu kerja relay sisi incoming.

Abstract

The limited interactive learning media regarding renewable energy in vocational schools has an impact on the low creativity and learning motivation of students. This study aims to develop a feasible, practical, and effective Arduino-based Solar Tracker Training Kit. Using the ADDIE model Research and Development (R&D) method, this research was conducted at SMKN 3 Jombang with 36 subjects of grade XI Industrial Electronics Engineering through a one-group pre-test post-test design. Data were collected through observation, interviews, questionnaires, and tests using validation sheet instruments, response surveys, and evaluation questions. Data analysis applied descriptive statistics percentages, N-Gain tests, and Wilcoxon tests because the data were not normally distributed (< 0.05). The results showed that the product was "Very Feasible" according to material experts (89.28%) and media experts (91.66%), and "Very Practical" based on student responses (82.36%). This tool was proven to be effective in increasing creativity (N-Gain 0.79) and learning motivation (N-Gain 0.82) in the high category. The Wilcoxon test confirmed the findings with a significant difference between pre-test and post-test scores (Asymp. Sig. < 0.05). It was concluded that this media is feasible and effective for implementation in vocational schools. Future development is recommended to integrate an IoT-based monitoring system and develop specific teaching modules.

Abstract

This study examines the effect of Simurelay software-based learning media on students&#x2019; computational thinking skills and creativity in the context of Electric Motor Installation subject at vocational secondary school. A quasi-experimental design with a Nonequivalent Control Group Design was employed involving 60 tenth-grade students (TITL) at SMKN 1 Driyorejo, divided equally into an experimental group using Simurelay (n = 30) and a control group using PowerPoint (n = 30). Data were collected through validated pretest and posttest instruments and analysed using N-Gain scores, independent sample t-test, and MANOVA. Results indicate that Simurelay did not produce a statistically significant effect on computational thinking (Sig. = 0.708 > 0.05), whereas it yielded a significant effect on creativity (Sig. = 0.011 < 0.05). N-Gain scores for both variables were categorised as moderate in both groups. These findings suggest that simulation-based media is more appropriate for cultivating creativity through open-ended exploration, while the development of computational thinking demands more systematic, algorithm-oriented, and long-term pedagogical strategies.

Abstract

Electrical systems in Water Treatment Plants require reliable protection systems to ensure the continuity of equipment operation, particularly pump motors. Short-circuit faults can produce large fault currents that may damage equipment and disrupt operational processes. This study aims to analyze short-circuit currents and evaluate the coordination of Over Current Relays (OCR) in the electrical distribution system of IPAM based on the IEEE Std. 242 standard. The research was conducted by modeling the electrical system using ETAP software based on the single line diagram, transformer data, motor data, and existing relay settings. The analysis results show that the maximum short-circuit current on the 0.4 kV side ranges from 32,270–35, 850 A, while on the 20 kV side it is approximately 3,128 A. The Time Current Characteristic (TCC) curve indicates that the feeder relay operating time ranges from 0.02 to 0.07 seconds, with a Coordination Time Interval (CTI) of approximately 0.2–0.3 seconds, which complies with the IEEE 242 standard (0.2-0.4 seconds). These results indicate that the protection coordination system operates selectively and reliably
