Saat ini listrik merupakan sumber energi utama masyarakat dan sangat dibutuhkan, kebutuhan pasokan energi listrik pelanggan yang semakin meningkat menutut sistem dalam jaringan distribusi untuk mempunyai tingkat keandalan sistem yang tinggi agar kebutuhan pasokan energi listrik pelanggan dapat optimal. Metode Section Technique digunakan adalah metode terstruktur untuk menganalisis sistem yang memungkinkan mengevaluasi sistem distribusi tenaga listrik berdasarkan kegagalan peralatan dan kinerja sistem. Ada beberapa indeks keandalan sistem yang dijadikan acuan dalam melakukan analisis sistem, khususnya System Average Interruption Frequency Indexs (SAIFI) dan System Average Interruption Duration Indexs (SAIDI). Hasil perhitungan dengan metode Section Technique nilai SAIFI 13,05512136 kali/tahun, sedangkan nilai SAIDI 13,0517974 jam/tahun.

Currently, electricity is the main energy source for society and highly needed. The increasing need for costomers’ electrical energy supplies requires system in the distribution network to have high level of system realiability so that costumers’ electrical energy supply needs can be optimized. Section Technique Method used wa a structured method for analyzing system that allows evaluating electric power distribution system based on equipment failures and system performance. There are several system realibility indexes that are used as references in conducting system analysis, in particular the System Avarege Interruption Frequency Index (SAIFI) and Sytem Avarege Interruption Duration Index (SAIDI). Calculation result using the Section Technique Method SAIFI value 13.05512136 times/years, while SAIDI value 13.0517974 hours/years. Keywords: Reliability, Section Technique, SAIDI, SAIFI
