Abstract

Miynak sawit mentah (CPO) adalah komoditas vital Indonesia, dengan mesin screw press berfungsi sebagai aset penting dalam proses ekstraksinya. Waktu  mati yang tidak terduga bisa mengganggu proses produksi dan mengurangi pendapatan. Penelitian ini menganalisis keandalan mesin screw press di PT MAS dengan memadukan Failure Mode and Effect Analysis (FMEA) dan Reliability Block Diagram (RBD). FMEA diterapkan untuk mendeteksi komponen kritis berdasarkan Risk Priority Number (RPN), sementara RBD digunakan untuk mengevaluasi keandalan sistem secara keseluruhan. Berdasarkan data historis tahun 2024, komponen dengan RPN tertinggi adalah Press Cage (144) dan Worm Screw (126). Analisis RBD menunjukkan adanya penurunan keandalan seiring waktu, yaitu 41,82% pada 112 jam dan 0% pada 1440 jam. Mean Time Between Failure (MTBF) komponen kritis sebesar 1344 jam. Disarankan pemeliharaan preventif dilakukan setiap sebelum 112 jam untuk menjaga keandalan di atas 50,00%, dengan fokus pada Press Cage dan Worm Screw.

Abstract

Production Suction Dredger (KIP) are the primary equipment for offshore tin mining, operating with a hydraulic system to drive the dredge, significantly impacting production efficiency. This study aims to measure and analyze the reliability of the dredge at KIP Timah 7 using a partial approach to the Overall Equipment Effectiveness (OEE) method, focusing on two main components: availability and performance. Data were obtained from operational reports for the 2023–2024 period, covering downtime, uptime, and monthly disruptions. The data will be processed monthly to obtain availability and performance values, then combined to calculate OEE as an indicator of work Effectiveness.  The results show that availability fluctuates between 81.30% and 100%, while performance remains constant at 100% because actual operating time meets the ideal target. The OEE value varies following changes in availability each month. The disruption analysis identified the soil pump cardan shaft, soil pump, and press pipe as the most frequently damaged components, increasing downtime. Therefore, scheduled maintenance is required on these critical components to improve work efficiency while minimizing potential production disruptions.
