A R Wilogo is a mining engineer with experience in open pit mine planning and operational optimisation within contractor-based nickel mining environments in Indonesia. He holds a bachelor’s degree in mining engineering and has been involved in short- to medium-term planning, haulage optimisation, equipment productivity analysis and cost control initiatives. His professional focus includes improving operational stability through structured sequencing, fleet configuration assessment and production variability reduction. Wilogo has worked closely with site operations teams to align tactical execution with strategic mine planning objectives, particularly in high-tonnage laterite nickel operations. His recent work explores the integration of semi-fixed conveyor systems into open pit haulage strategies to enhance cost predictability and long-term project value. He is interested in strategic mine planning, operational transformation and value optimisation frameworks that improve consistency and sustainability in surface mining operations
