Abstract
Penelitian ini bertujuan untuk menganalisis kelayakan sekaligus melakukan upaya perbaikan pada sistem pentanahan SUTT PLTMG Flores – GI Labuan Bajo berdasarkan nilai pentanahan standar Kepdir PT. PLN (Persero) PDM/STT/10:2014 dan IEEE Std 80-2013. Penelitian ini dilakukan dengan metode pengambilan data kuantitatif yang diperoleh melalui pengukuran langsung di lingkup SUTT PLTMG Flores – GI Labuan Bajo. Analisis hasil akhir penilitan ini dilakukan menggunakan metode komparasi. Analisis hasil akhir penilitan ini dilakukan menggunakan metode komparasi. Metode analisis dengan menggunakan metode komparasi, dalam hal ini yang dibandingkan adalah nilai resistansi pentanahan setiap kaki tower pada saluran transmisi PLTMG Flores – GI Labuan Bajo dengan hasil perhitungan matematis yang ada. Pengukuran dari 34 tower pada SUTT 70 kV PLTMG Flores – GI Labuan Bajo memiliki persentase kelayakan sebesar 71,11%, dimana yang tidak layak sebesar 28,89% karena melebihi batas standar 5 Ω. Perbaikan yang paling efektif untuk diterapkan adalah perbaikan dengan metode counterpoise karena memiliki penurunan nilai resistansi yang lebih baik (72,15%) dan lebih ekonomis dari metode penambahan elektroda (Rp 86.272.000,00). Penelitian ini diharapkan dapat menjadi referensi bagi penelitian selanjutnya dan memberikan informasi berharga bagi pengelola dan pemilik aset saluran transmisi dalam meningkatkan kinerja sistem pentanahan.

This study aims to analyze the feasibility and improvements in the grounding system of the 70-kV transmission line of PLTMG Flores – GI Labuan Bajo based on the standard grounding of Kepdir PT. PLN (Persero) PDM/STT/10:2014 and IEEE Std 80-2013. The study is using quantitative data collection methods obtained through direct measurements within the scope of the 70-kV transmission line of PLTMG Flores – GI Labuan Bajo. The final analysis of this research was conducted using a comparative method. In this case, the grounding resistance values of each tower leg on the transmission line from PLTMG Flores to GI Labuan Bajo were compared with the existing mathematical calculation results. Measurements from 34 towers on the 70-kV transmission line of PLTMG Flores – GI Labuan Bajo show a feasibility percentage of 71,11%, with 28,89% being non-compliant as they exceed the standard limit of 5 Ω. The most effective improvement method to be applied is the counterpoise method because it has a better reduction in resistance value (72,15%) and is more economical compared to the electrode addition method (Rp 86.272.000,00). This study is expected to serve as a reference for future research and provide valuable information for managers and owners of transmission line assets in improving the performance of the grounding system.
