Value stream mapping adalah metode dari konsep lean manufacturing yang bertujuan untuk memetakan aliran material dan informasi pada sebuah proses. Dibantu dengan metode waste relationship matrix, jenis-jenis waste pada peta value stream dapat teridentifikasi sehingga dapat dimitigasi dengan value stream mapping analysis tool yang sesuai. Riset ini bertujuan untuk menerapkan value stream mapping pada proses perbaikan rotating equipment yaitu pompa jenis Pump P04-CD3 yang merupakan equipment untuk menyokong aktivitas produksi minyak. Setelah penerapan metode, jenis-jenis waste yang menjadi akar permasalahan dari proses perbaikan equipment tersebut adalah transportation waste, process waste dan motion waste. Setelah dilakukan improvement, lead time perbaikan berkurang sebanyak 46.7%, cycle time perbaikan berkurang sebanyak 3.8% dan non-value-added time berkurang sebanyak 57.9%.

Value stream mapping is a method derived from the lean manufacturing concept which aims to map the flow of material and information of a process. Assisted by the waste method relationship matrix, the types of waste on the value stream map can be identified so that it can be mitigated with an appropriate value stream mapping analysis tool. This research aims to apply value stream mapping to the repair process of rotating equipment, namely Pump P04-CD3 which is equipped to support oil production activities. After the application of the method, the types of waste that become the root cause of the equipment repair process problem are transportation waste, process waste and motion waste. After improvement, the repair lead time was reduced by 46.7%, the repair cycle time decreased by 3.8%, and the non-value-added time decreased by 57.9%.
