Abstract
Kondisi Persaingan yang ketat dalam bisnis pembangkit listrik menuntut para produsen listrik menyediakan pasokan energi listrik dengan biaya pokok penyediaan (BPP) yang rendah. Disisi lain, banyaknya aset peralatan yang dikelola oleh perusahaan pembangkit listrik mengharuskan adanya proses management aset yang tepat, guna menekan adanya potensi peningkatan biaya pemeliharaan dan investasi peralatan yang berimbas pada kenaikan BPP. PT. Pembangkitan Jawa Bali (PT. PJB) sebagai perusahaan yang mengelola aset lebih dari Rp 174 triliun memiliki tantangan dalam proses mengoptimalkan pengelolaan manajemen aset perusahaannya. Semakin berkurangnya jumlah anggaran pemeliharaan dan investasi pada perusahaan serta kondisi peralataan yang sudah beroperasi lebih dari 20 tahun menuntut adanya metode management aset yang dapat memberikan pemahaman secara menyeluruh terhadap kondisi teknis dan ekonomis setiap peralatannya, sehingga dapat memberikan informasi yang tepat guna mendukung proses pengambilan keputusan yang diharapkan dapat menekan BPP. Pada Penelitian ini dilakukan analisis kondisi aset di PT. PJB dengan menggabungkan metode analisis Keandalan (Reliability) dan perhitungan umur ekonomis (Economic Life) peralatan. Studi kasus dilakukan pada salah satu unit di PT. Pembangkit Listrik Z tepatnya di PLTGU ST #2. Tujuan dari penelitian ini untuk mendapatkan informasi secara menyeluruh mencakup nilai keandalan dan umur ekonomis setiap peralatan unit untuk memudahkan manajemen dalam proses pengambilan keputusan untuk pemilihan strategi pemeliharaan dan pengantian aset. Analisis keandalan dilakukan dengan menggunakan software RBD, RGA, dan Weibull. Perhitungan reliability dilakukan dengan melihat jumlah dan waktu antar kerusakan. Perhitungan umur ekonomis dilakukan dengan menghitung biaya ekuivalen tahunan. Analisis dilakukan pada setiap peralatan kritis yang terdapat pada PLTGU ST #2. Dari analisis tersebut didapatkan startegi perumusan penggantian aset peralatan pembangkit berupa klasifikasi peralatan berdasarkan batasan – batasan parameter yang digunakan. Selain itu dihasilkan peta kondisi keandalan dan umur ekonomis yang menggambarkan jumlah peralatan yang harus segera diganti, tetap dipelihara, dan perlu segera dievaluasi strategi perawatannya. Sehingga informasi ini dapat digunakan manajemen dalam memutuskan evaluasi strategi pemeliharaan dan penggantian guna menekan biaya pokok penyediaan.

In a competitive market driven industry at a power generation business, requires The electricity producers to provide electricity with a low cost of supply. On the other hand, the large number of equipment assets managed by the power plant companies requires an appropriate asset management process, in order to reduce the increased maintenance and investment costs of equipment which which can cause an increase in the cost of supply. PT. Pembangkitan Jawa Bali (PT. PJB) as a company that manages assets of more than Rp 174 trillion has challenges in the process of optimizing its company's asset management. The decreasing amount of maintenance and investment budget in the company each year and the equipment conditions that have been operated for more than 20 years, requires an asset management method that can provide a comprehensive understanding of the technical and economic conditions of each equipment, so it can be provide appropriate information to support the decision making process. In this study, the authors conducted an analysis of asset conditions at PT. PJB by combining the method of reliability analysis and calculation of the economic life of the equipment. Case study was conducted at one of the units at PT. PJB precisely in PLTGU ST # 2. The purpose of this study is to obtain comprehensive information including the value of reliability and economic life of each equipment in the unit to facilitate management in the decision making process for the selection of maintenance strategies and asset replacement. Reliability analyzes were performed using RBD, RGA, and Weibull software. Reliability calculation will be done by looking at the amount and time between damages. Economic life calculation is done by calculating the annual equivalent cost. The analysis was performed on each equipment in the PLTGU ST # 2. From the analysis, It's founded the formulation of replacement strategy for power plant equipment in the form of equipment classification based on the parameters used. In addition, equipment condition maps are also obtained based on the reliability index and economic life that describe the number of equipment that must be replaced, keep, and need further maintenance analysis. So this information can be used by management in deciding the evaluation of maintenance and replacement strategies to reduce the cost of supply.
