Each mining company has accountability to ensure all affected areas due to mining <br /> <br /> operation are in good condition prior to close and leave the mine. As part of mine closure <br /> <br /> plan of Grasberg open pit mine, Lower Wanagon project is very critical for PT Freeport <br /> <br /> Indonesia. Lower Wanagon project objectives is to comply with reclamation commitment <br /> <br /> and to guarantee the geotechnical stability of Lower Wanagon Overburden Stockpiles, the <br /> <br /> largest waste rock stockpiles in Grasberg open pit mine, PT Freeport Indonesia. Lower <br /> <br /> Wanagon project was initially planned to complete in 2024. <br /> <br /> The completion of Lower Wanagon project as per design and schedule is a key concern for <br /> <br /> company as it will directly impact to environmental and social issues. Failure to achieve <br /> <br /> target will potentially lead PT Freeport Indonesia to a catastrophic risk. Therefore, many <br /> <br /> efforts has been done by company including dedicated a business unit, equipment and <br /> <br /> material for this project execution. Nevertheless, the project performance is very poor. The <br /> <br /> project is currently behind the target about three years and cost increasing significantly <br /> <br /> from USD 700 million to USD 840 million due to this delay. This delay will also escalate <br /> <br /> the landslide potential, one of catastrophic risk faced by company. <br /> <br /> This final project is intended to analyze and study the issues regarding poor project <br /> <br /> performance in Lower Wanagon project, find out the root cause as well as provide best <br /> <br /> recommendation in order to speed up the progress and improve project performance. Cause <br /> <br /> and effect (fishbone) diagram is utilized as a tool to find out the root causes. Analytic <br /> <br /> Hierarchy Process (AHP) method is used to solve the root causes by determining and <br /> <br /> evaluating the best business unit to finish Lower Wanagon project. <br /> <br /> The AHP calculation resulted in business unit of Petrosea as the best solution to finish <br /> <br /> Lower Wanagon project with consolidated weight of 0.4044. With this solution, it is <br /> <br /> confidently projected that the project completion will be faster about three years from <br /> <br /> actual condition or project can be finished as per original target and saving money (avoid <br /> <br /> potential additional cost) about USD 87.6 million. The solution also will lower the potential <br /> <br /> risk of landslide from high to low and preserve company reputation regarding best mining <br /> <br /> practice and compliance to government regulation.
