Abstract
Penelitian ini membahas analisis biaya siklus hidup aset (subsistem) selama planning horizon pabrik (sistem) di PLTU 3 PT PJB Unit Pembangkit Gresik. Permasalahan yang dihadapi adalah menentukan umur ekonomis dan penggantian aset agar dapat memberikan service selama planning horizon pabrik. Analisis biaya siklus hidup melibatkan estimasi dari biaya, inflasi, dan kurs yang berpotensi memiliki perbedaan dengan realisasi sehingga diperlukan prosedur untuk membuat keputusan yang tepat. Prosedur dirancang dengan melakukan beberapa eksperimen perhitungan pada dua aset yang dianggap mewakili keseluruhan aset yang ada. Metode yang digunakan adalah equivalent uniform annual cost (EUAC) untuk mendapatkan umur ekonomis, analisis penggantian untuk menentukan keputusan keep atau keep and improve atau replace, serta rolling planning horizon (RPH) untuk menentukan durasi pemakaian aset. Hasil eksperimen menunjukkan bahwa keputusan pemakaian aset ditentukan berdasarkan umur ekonomis yang dihitung secara berkala dengan mengabaikan sunk cost. Penelitian ini merekomendasikan prosedur planning untuk merencanakan pengelolaan aset pada saat awal penggunaan aset dan prosedur controlling untuk mengkonfirmasi perbedaan data estimasi dan rill serta menentukan waktu penggantian yang tepat.
=======================================================
This study discusses the analysis of asset life cycle costs (subsystems) during the planning horizon of the plant (system) at PLTU 3 PT PJB Gresik Power Plant. The problem faced is determining the economic age and asset replacement in order to provide service during the plant planning horizon. Life cycle cost analysis involves estimating costs, inflation, and exchange rates that probably differ from real data so that procedures are needed to make the right decisions. The procedure is designed by performing experiments on two assets which are considered to represent all existing assets. The method is used equivalent uniform annual cost (EUAC) to obtain economic life, replacement analysis to determine the decision to keep or keep and improve or replace, and the rolling planning horizon (RPH) to determine the duration of asset use. The experimental results show that the decision to use assets is determined based on the economic age which is calculated periodically by ignoring the sunk cost. This study recommends planning procedures to plan asset management at the time of initial use of assets and controlling procedures to confirm differences in estimated and real data and also determine the appropriate replacement time.
