MAINTENANCE STRATEGY FOR ROTARY BRIQUETTE MACHINES AT PT. ARKATAMA INDONESIA USING FMEA METHOD

inggris and indonesian

Abstract

his internship report focuses on studying the maintenance approach for rotary sieve machines at PT.
Arkatama Indonesia, a company that makes coconut briquettes with a monthly production capacity of 100
tons. This topic is important because it helps make machines more reliable and improves product quality
by using a more forward-thinking method. The methods used are Failure Mode and Effect Analysis
(FMEA) to assess the risk of damage using the RPN value, and Reliability Centered Maintenance (RCM)
with calculations for failure rate (λ) and system reliability. The results show that the Shaft Mount has the
highest RPN value and the lowest reliability rate (4.95%), so it needs a Predictive Maintenance method.
The Rotary Screen has a reliability level of 13.42%, and the Vanbelt Motor has 36.99%, which means
they are suitable for Preventive and Corrective Maintenance. Using FMEA was very effective in making
the operations run more smoothly, lowering machine downtime, and helping the company move towards
Industry 4.0 at PT. Arkatama Indonesia.
