Abstract

Tegangan tembus merupakan salah satu parameter penting dalam sistem isolasi listrik yang menentukan batas kemampuan suatu medium dalam menahan medan listrik sebelum terjadi pelepasan muatan listrik (breakdown). Material elektroda yang digunakan dalam sistem bertegangan tinggi sangat mempengaruhi distribusi medan listrik dan nilai tegangan tembus yang dihasilkan. Oleh karena itu, penelitian ini dilakukan untuk mengkaji karakteristik tegangan tembus dari berbagai jenis material elektroda dalam medan listrik seragam. Studi ini secara khusus membandingkan empat jenis logam, yaitu stainless steel, aluminium, tembaga, dan kuningan, yang umum digunakan dalam aplikasi kelistrikan. Pengujian dilakukan secara eksperimental di Laboratorium Tegangan Tinggi dengan menggunakan konfigurasi elektroda bola-bola, jarum-jarum, dan pelat-pelat pada medium udara. Hasil pengujian menunjukkan bahwa material elektroda memiliki pengaruh signifikan terhadap besar tegangan tembus. Stainless steel secara konsisten menunjukkan performa terbaik dengan nilai tegangan tembus tertinggi pada semua konfigurasi, yakni 8,07 kV (bola-bola), 8,21 kV (jarum-jarum), dan 6,37 kV (pelat-pelat). Sebaliknya, tembaga menghasilkan tegangan tembus terendah, khususnya pada konfigurasi pelat-pelat sebesar 3,27 kV. Aluminium dan kuningan menunjukkan hasil yang bervariasi, namun masih di bawah performa stainless steel

Abstract

Penelitian ini bertujuan untuk meningkatkan sifat isolasi dielektrik material isolator berbahan dasar tanah liat melalui penambahan cullet dan gypsum, hal ini menjadi upaya penting bagi pengembangan material isolator yang efisien. Tanah liat, sebagai sumber daya melimpah, memiliki potensi besar namun membutuhkan peningkatan performa dielektrik. Metode eksperimental digunakan untuk membuat tujuh variasi sampel berbentuk persegi (40 mm×40 mm×10 mm) dengan proporsi cullet (5%, 10%), gypsum (5%, 10%), dan kombinasinya. Sampel diuji tegangan tembus menggunakan tegangan tinggi AC. Hasil menunjukkan bahwa penambahan cullet dan gypsum secara konsisten meningkatkan tegangan tembus, dengan kombinasi 10% cullet + 10% gypsum mencapai nilai tertinggi 43,78 kV (4,38 kV/mm). Meskipun belum memenuhi standar PLN (9,85 kV/mm), penelitian ini menginformasikan potensi aditif dalam meningkatkan performa isolasi khususnya berbahan dasar tanah liat

Abstract

Collaborative learning has the potential to address these challenges by promoting problem-solving through collective participation within groups. This research investigates the effect of the Jire Collaborative Learning model integrated with Phylearn media on students’ learning outcomes regarding heat and temperature. The study was motivated by low student achievement, primarily attributed to conventional teaching methods to engage students in active participation. This quasi-experimental research employed a one-group pre-test-post-test design involving 25 seventh-grade students at SMP Negeri 4 Monano. The Jire Collaborative model emphasizes active student collaboration, while Phylearn provides interactive multimedia support to help visualize abstract scientific concepts. The findings reveal a significant improvement in students’ cognitive performance (levels C2-C4) after the intervention, indicating that the integrated approach effectively improves conceptual understanding. This influence is demonstrated by the difference in students’ learning outcomes before and after applying the JIRE model, where the average pre-test score of 46.4 increased to 81.05 in the post-test. The t-test results indicate that this difference is statistically significant, with a significance value of 2.10, less than 0.05. These findings confirm a significant difference between students’ pre-test and post-test scores after applying the JIRE collaborative learning model, indicating that this model effectively improves students’ learning outcomes. These results suggest that technology-supported collaborative learning is a promising strategy for improving the quality of science education at the junior high school level.

Abstract

Lightning disturbances often cause induced overvoltages on 20 kV medium voltage distribution overhead lines, which can shorten equipment life and trigger power outages. This study aims to evaluate the cutting performance of two types of lightning arresters made of ceramic and polymer in reducing lightning-induced voltage surges through high-voltage impulse testing in the laboratory. The tests replicated standard impulse waves and were conducted in stages at 20 kV, 30 kV, 40 kV, and 50 kV levels, with each level repeated several times for data reliability. The main parameters analyzed included the measured peak voltage, response time (μs), and the cutting percentage compared to unprotected conditions, based on validated oscilloscope readings (time/div and volt/div). The results showed that both arresters reduced the induced voltage in most test scenarios, with the highest effectiveness occurring at 30 kV impulses. Quantitatively, ceramic arresters achieve a cutoff of 0.39–4.17 V (2.27–22.3%), while polymer arresters achieve 1.46–4.67 V (8.44–24.97%), and at 20 kV no significant cutoff is observed. In general, the performance of polymer lighting arresters is better than ceramic lighting arresters, which indicates the ability of polymer materials and housing designs to maintain lower residual voltages when facing fast transients Abstrak Gangguan petir seringkali menimbulkan tegangan lebih terinduksi pada saluran udara distribusi tegangan menengah 20 kV yang berakibat memperpendek umur peralatan dan memicu pemadaman listrik. Penelitian ini bertujuan mengevaluasi kinerja pemotongan dua tipe lightning arrester berbahan keramik dan berbahan polimer dalam mereduksi lonjakan tegangan akibat induksi petir melalui pengujian impuls tegangan tinggi di laboratorium. Pengujian mereplikasi gelombang impuls standar dan dilakukan bertingkat pada level 20 kV, 30 kV, 40 kV, dan 50 kV dimana setiap level diulang beberapa kali untuk reliabilitas data. Parameter utama yang dianalisis meliputi tegangan puncak terukur, respons waktu (μs), serta persentase pemotongan terhadap kondisi tanpa proteksi, berdasarkan pembacaan osiloskop yang telah divalidasi (time/div dan volt/div). Hasil menunjukkan kedua arrester menurunkan tegangan induksi pada sebagian besar skenario uji, dengan efektivitas tertinggi muncul pada impuls 30 kV. Secara kuantitatif, arrester keramik mencapai pemotongan 0,39–4,17 V (2,27–22,3%), sedangkan arrester polimer 1,46–4,67 V (8,44–24,97%) dan pada tegangan 20 kV tidak teramati pemotongan berarti. Secara umum kinerja lighting arrester polimer lebih baik dibandingkan lighting arrester berbahan keramik, yang mengindikasikan kemampuan material dan rancangan housing polimer untuk menjaga tegangan residual lebih rendah saat menghadapi transien cepat

Abstract

Transformer oil insulation breakdown voltage testing is usually carried out at high AC voltage using the SPLN 49-1 1982 standard. The electrodes used are hemispherical electrodes with a distance between the electrodes of 2.5mm. The breakdown voltage value of transformer oil insulation that meets the standards according to SPLN 49-1 of 1982 is 30 kV/2.5mm. In this research, a new Shell Diala B brand transformer oil insulation breakdown voltage test was carried out using the SPLN 49-1 1982 testing standard. The novelty of this research is using various electrode shapes and different electrode materials to test the breakdown voltage of the transformer oil's liquid insulation. The method used in this research is an experimental method where the test is adapted to the SPLN 49-1 standard of 1982. The electrodes used are ball, needle, and plate electrodes. Based on test results at a distance between electrodes of 2.5 mm, it was found that the breakdown voltage characteristics of stainless steel, brass, copper, and aluminum electrode materials varied and did not meet the SPLN 49-1 1982 standard, namely 30 kV/2.5 mm.
