Abstract

Banyak studi telah dilakukan tentang evaluasi risiko (risk assessment) pada transformator distribusi. Namun, penelitian sebelumnya belum sepenuhnya mempertimbangkan analisis risiko dan dampak biaya akibat kerusakan pada transformator distribusi. Selain itu, penggunaan Metode Biaya Total Dimodifikasi (Modified Total Ownership Cost) menjadi salah satu pendekatan komprehensif untuk menghitung implikasi biaya dari kerusakan pada transformator distribusi. Penggunaan matriks risiko (risk matrix) untuk menentukan faktor kemungkinan (likelihood factor) dan faktor konsekuensi (consequence factor) masih kurang mempertimbangkan beberapa faktor, dan faktor-faktor yang digunakan sering memiliki bobot yang sama dan saling terkait. Penelitian ini mengumpulkan semua indikator yang digunakan untuk faktor kemungkinan dan konsekuensi dalam matriks risiko, dan menerapkan Analytic Network Process untuk memberikan bobot pada faktor-faktor tersebut. Hasilnya adalah sebuah model evaluasi risiko yang lebih akurat, mendukung pengambilan keputusan terkait investasi pada transformator distribusi di Jawa Timur. Matriks risiko yang telah dimodifikasi dan diberi bobot diterapkan pada 65 transformator distribusi, di mana 3 di antaranya memiliki risiko rendah, 15 risiko moderat, 37 risiko tinggi, 8 risiko sangat tinggi, dan 2 memiliki risiko ekstrem.

Many studies have been conducted on risk assessment in distribution transformers. However, previous studies have not fully considered the risk analysis and cost impact of damage to distribution transformers. In addition, the use of the Modified Total Ownership Cost Method is one comprehensive approach to calculating the cost implications of damage to distribution transformers. The use of risk matrix to determine likelihood factors and consequence factors still does not consider several factors, and the factors used often have equal weight and are interrelated. This study collects all the indicators used for probability and consequence factors in the risk matrix and applies the Analysis Network Process to give weight to those factors. The result is a more accurate risk evaluation model, supporting decision-making regarding investment in distribution transformers in East Java. A modified and weighted risk matrix was applied to 65 distribution transformers, of which 3 had low risk, 15 had moderate risk, 37 had high risk, 8 had very high risk, and 2 had extreme risk.
