Abstract
Sebagai Badan Usaha Milik Negara, PLN dituntut untuk menyediakan tenaga listrik bagi kepentingan umum dalam jumlah dan kualitas yang memadai namun di sisi lain sesuai dengan anggaran dasar PLN dituntut untuk memperoleh keuntungan. Kegagalan transformator daya memiliki dampak yang signifikan terhadap keandalan sistem kelistrikan, karena dapat mengganggu penyaluran tenaga listrik dan mengurangi pendapatan perusahaan. Banyak penelitian yang telah dilakukan mengenai health index transformator daya. Namun penelitian-penelitian sebelumnya hanya mempertimbangkan health index dari satu atau beberapa aspek hasil pengujian saja. Penggunaan Life Cycle Cost adalah metode yang membantu memilih pendekatan biaya terbaik untuk pemilihan strategi pemeliharaan yang efektif selama masa pakai transformator. Umur rata-rata transformator menggunakan Analisis Weibull terhadap kegagalan transformator di PLN TJBT dari tahun 2017-2022. Penelitian ini menggunakan health index komprehensif dengan mempertimbangkan mode kegagalan pada transformator yang mengintegrasikan hasil dari berbagai aspek, seperti pengamatan saat beroperasi, inspeksi lapangan, pengujian di lapangan dan laboratorium. Setelah melakukan indeks kesehatan yang komprehensif, evaluasi risiko dilakukan untuk mensimulasikan dampak dari keputusan pemeliharaan yang berbeda. Dengan mempertimbangkan health index dan life cycle cost transformator, sebuah model pengambilan keputusan pemeliharaan baru dikembangkan untuk memilih strategi pemeliharaan terbaik berdasarkan kondisi transformator saat ini.

As a State-Owned Enterprise, PLN is required to provide electricity for the public interest in sufficient quantity and quality but on the other hand according to the articles of association PLN is required to make a profit. Power transformer failures have a significant impact on electrical system reliability, as they can disrupt electricity delivery. Many studies have been conducted on health index of power transformer. However previous studies only considered health index from one or several aspect of testing result. Use of Life Cycle Cost is a method that helps select the best cost approach for selection of an effective maintenance strategy over the transformer's lifetime . Lifetime of transformer use a Weibull Analysis of failure transformer in PLN TJBT from 2017-2022. This study use a comprehensive health index by considering failure modes in transformers that integrate results from various aspects, such as observations while in operation, field inspections, on-site and laboratory testing. After conducting comprehensive health index, a risiko evaluation was perform to simulate the impact of different maintenance decision. Considering health index and life cycle cost of transformer, a new maintenance decision making model was developed to choose the best maintenance strategy based on current condition of transformer.
