Abstract
Coal is the largest resource for 38% of coal power plants in the world, in Indonesia electric power plants dominate with total installed power reaching 20,750.50 MW or 48.43%. Belt conveyor is the main equipment for transporting coal to the boiler. The phenomenon of conveyor belt damage such as tearing, peeling, and breaking is an event that occurs in many industries in the world. The purpose of this study is to Batubara menjadi sumber daya terbesar di 38% dari pembangkit listrik tenaga batubara di dunia, di indonesia pembangkit listrik tenaga batubara mendominasi dengan jumlah daya terpasang mencapai 20.750,50 MW atau 48.43%. Belt conveyor merupakan peralatan utama pengangkut batubara menuju boiler. Fenomena kerusakan belt conveyor seperti sobek, terkelupas, dan putus merupakan kejadian yang terjadi di banyak industri didunia. Tujuan dari penelitian adalah Menganalisis akar masalah penyebab penurunan nilai OEE belt conveyor pada PLTU, memberikan rekomendasi perbaikan untuk mengatasi penurunan nilai OEE belt conveyor pada PLTU. Hasil penelitian terdapat pengaruh yang signifikan antara belt rusak dengan OEE, OEE dengan produktivitas, dan belt rusak terhadap produktivitas melalui OEE, hasil analisis menggunakan metode RCFA didapat 2 penyebab utama menurunya produktivitas yaitu akibat belt sobek sisi tepi dan belt terkelupas, kemudian didapatkan prioritas perbaikan kerusakan belt conveyor menggunakan metode FMEA berdasarakan nilai risk priorty number (RPN ) tertinggi. Kata Kunci: Belt conveyor, FMEA, OEE, RCFA, SEM-PLS analyze the root cause of the decline in the value of the OEE belt conveyor at the steam power plant, provide recommendations for improvement to overcome the decrease in the value of the OEE belt conveyor at the steam power plant. The results of the study showed that there was a significant effect between damaged belts with OEE, OEE with productivity, and damaged belts on productivity through OEE, the results of the analysis using the RCFA method obtained 2 main causes of productivity decline, namely due to torn side belts and peeling belts, then obtained an increase in damaged conveyor belt repairs using the FMEA method based on the highest risk priority number (RPN). Keyword: Conveyor Belt, FMEA, OEE, RCFA, SEM-PLS
