Abstract
Planned Outage pada Pembangkit Listrik Tenaga Uap (PLTU) merupakan kegiatan pemeliharaan yang berdampak langsung terhadap ketersediaan unit dan biaya operasional. Penelitian ini bertujuan mengevaluasi dan menurunkan lead time during-outage melalui integrasi Lean Maintenance, Critical Chain Project Management (CCPM), dan Resilience Engineering. Lean Maintenance digunakan untuk memetakan aliran proses menggunakan Maintenance Value Stream Mapping (M-VSM), mengidentifikasi waste, serta mengklasifikasikan aktivitas menjadi Value Added (VA), Necessary Non-Value Added (NNVA), dan Non-Value Added (NVA). Prinsip SMED diterapkan untuk mengurangi aktivitas yang tidak bernilai tambah, sedangkan CCPM digunakan untuk menyusun penjadwalan berbasis critical chain dan pengelolaan buffer. Resilience Engineering diterapkan melalui Rapid Triage Protocol untuk meningkatkan kemampuan sistem dalam merespons emergent work. Hasil penelitian menunjukkan bahwa lead time during-outage aktual sebesar 37,82 hari dapat diturunkan menjadi 25,01 hari. Nilai PCE meningkat dari 53,20% menjadi 71,47%, sementara proporsi NVA menurun dari 26,30% menjadi 16,03%. Penerapan CCPM menghasilkan durasi critical chain generator sebesar 22,01 hari yang terdiri atas aggressive estimate 12,13 hari dan Project Buffer 9,88 hari. Selain itu, nilai Resilience Index meningkat dari 0,33 menjadi 0,83 karena sebagian besar emergent work dapat dimitigasi tanpa menambah durasi outage dan juga scope. Hasil penelitian menunjukkan bahwa integrasi ketiga pendekatan tersebut mampu meningkatkan efisiensi proses, mengurangi pemborosan, dan memperkuat ketahanan sistem selama pelaksanaan planned outage.

Planned outage in a coal-fired power plant is a maintenance activity that directly affects unit availability and operational costs. This study aims to evaluate and reduce lead time during-outage through the integration of Lean Maintenance, Critical Chain Project Management (CCPM), and Resilience Engineering. Lean Maintenance is used to map the process flow using Maintenance Value Stream Mapping (M-VSM), identify waste, and classify activities into Value Added (VA), Necessary Non-Value Added (NNVA), and Non-Value Added (NVA). SMED principles are applied to reduce non-value-added activities, while CCPM is used to develop critical chain-based scheduling and buffer management. Resilience Engineering is applied through the Rapid Triage Protocol to improve the system’s ability to respond to emergent work. The results show that the actual lead time during-outage of 37.82 days can be reduced to 24.01 days. The PCE value increases from 53.20% to 71.47%, while the proportion of NVA decreases from 26.30% to 16.03%. The implementation of CCPM results in a generator critical chain duration of 22.01 days, consisting of an aggressive estimate of 12.13 days and a Project Buffer of 9.88 days. In addition, the Resilience Index increases from 0.33 to 0.83 because most emergent work can be mitigated without extending the outage duration. The results indicate that the integration of these three approaches can improve process efficiency, reduce waste, and strengthen system resilience during planned outage execution.
