Abstract

Listrik memegang peranan yang sangat penting dalam kehidupan. Adanya energi listrik membantu manusia dalam memenuhi dan menyelesaikan kebutuhan hidupnya. Dengan semakin tingginya konsumsi energi listrik yang dibutuhkan oleh masyarakat, membuat PT.PLN (Persero) APP Surabaya harus menyediakan pasokan energi listrik dengan kualitas yang memadai dan tidak boleh putus selama 24 jam.Transformator adalah salah satu peralatan yang sangat penting dalam penyaluran listrik. Kegagalan fungsi transformator ini mengakibatkan pasokan listrik ke pelanggan menjadi terganggu dan berkurang sehingga menimbulkan kerugian yang besar bagi pelanggan seperti tidak berjalannya proses produksi industri dan juga kehilangan pendapatan bagi PT.PLN (Persero) APP Surabaya, oleh karena itu permasalahannya adalah bagaimana karakterististik data lifetime transformator serta jadwal perencanaan perawatan transformator yang dapat mengoptimumkan biaya perawatan maupun perbaikan transformator. Permasalahan tersebut dapat diselesaikan dengan menggunakan metode reliability. Tujuan dari penelitian ini menentukan jadwal perencanaan yang menghasilkan besaran optimum untuk perwatan transformator. Berdasarkan hasil pengujian,jadwal perencanaan perawatan transformator berdasarkan distribusi Generalized Pareto yaitu setelah transformator beroperasi selama 9 bulan dengan estimasi biaya sebesar Rp 1.720.319 untuk penjadwalan dengan durasi bulanan, sedangkan penjadwalan dengan durasi tahunan yaitu setelah transformator beroperasi selama 1tahun 6 bulan dengan estimasi biaya sebesar Rp. 3.369.809. ==================================================================================================== Electricity has a very important role in the life. Electrical energy help people in fulfilling and completing the necessities of life. Demand for electrical energy consumption required by the public has increased, that PT PLN (Persero) Surabaya APP must provide an electric energy supply with adequate quality and should not be broken for 24 hours. The transformer is one of the vital equipment in an electric distribution. Transformer malfunction resulted in electricity supply to customers was interrupted, and reduced then cause large losses for customers such as industrial production process is inhibited and also the loss of income for PT.PLN (Persero) APP Surabaya. Reliability is an optimally maintenance method that combines a statistical approach for planning maintenance activities based on the reliability of a component. Therefore, the problem is how the characteristics of the data lifetime transformer and transformer maintenance planning schedule that can optimize the cost of maintenance and repair transformers. Those problems can be solved by using the reliability method. This study aims to determine the planning schedule transformer maintenance and optimum amount of transformer maintenance costs. Based on test results, schedule transformer maintenance planning based on Generalized Pareto distribution after the transformer in operation for 9 months with an estimated cost of Rp 1.720.319 for scheduling monthly duration, whereas the scheduling with the annual duration after the transformer in operation for 1 year 6 months with an estimated cost of Rp. 3.369.809
