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
