Abstract
Overstock spare part pada Sistem Transmisi Tenaga Listrik menyebabkan perusahaan tidak efisien sedangkan stockout spare part di perusahaan berdampak pada terganggunya proses pemeliharaan sistem transmisi tenaga listrik yang menyebabkan pemadaman listrik. Overstock spare part dikarenakan oleh beberapa hal, seperti kesalahan peramalan kebutuhan material, permintaan yang intermittent sehingga sulit melakukan penentuan jumlah kuantitas pemesanan optimal. Di sisi lain, ketidaktersediaan spare part saat dibutuhkan menyebabkan terganggunya keandalan sistem transmisi energi listrik yang berpotensi pemadaman listrik secara massal. Simulasi Monte Carlo dilakukan untuk memberi gambaran kondisi persediaan suku cadang dengan pendekatan periodic review (R,S) system secara lebih nyata. Penentuan kombinasi parameter R dan S sangat berpengaruh terhadap keberhasilan pengendalian Spare part. Klasifikasi Spare part dilakukan agar dapat mengetahui karakteristik demand dan tingkat kekritisannya, serta dengan analisa hasil simulasi dapat diperoleh informasi strategi pemenuhan persediaan untuk mengatasi masalah-masalah ketidaktersediaan spare part ataupun overstock.

Overstock spare part in the Electric Power Transmission System will affect the inefficiency in the asset management of the company. While the spare part stockouts in the company will disrupt the maintenance process of the electric transmission system, which then lead to power outages. Overstock spare parts are caused by several factors, such as forecasting errors in material requirements, intermittent requests, so it is difficult to determine the optimal order quantity. On the other hand, the unavailability of spare parts will affect the reliability of the electrical energy transmission system, which has the potential in causing a massive power outage. Monte Carlo simulations show the more concrete picture of the spare parts inventory condition using a periodic review (R, S) system approach. Divination of the combination of S and R parameters is very influential on the success of spare part control. Spare part classification is used for understanding the demand characteristics and the level of criticism. Moreover, the simulation results analysis will show the information on supply fulfilment strategies to overcome the problems of either spare parts availability or spare parts overstock.
