Abstract

PT XYZ is a manufacturing company that provides hot metal transportation handling services and supports Blast Furnace (BF) operations at the Krakatau Posco Plant using heavy equipment, namely Multi Mover M600U. To ensure smooth production processes, effective and efficient maintenance management of the heavy equipment are essential to enhance reliability. This study evaluates potential failure modes, their impacts and appropriate handling measures for the Multi Mover M600U using the Failure Mode and Effect Analysis (FMEA) method. The result of the study shows the highest Risk Priority Number (RPN) value of 350 in the Electrical PLC component, with a total RPN of 777 for the Electrical and Brake systems. These findings indicate that the Electrical and Brake systems have the highest failure rates due to downtime compared to other systems. Through the Reliability Centred Maintenance (RCM) approach, this study proposes a maintenance scheduling plan to minimize the risk of sudden downtimes, and their impacts on time and maintenance costs.Keywords - Downtime, Failure Mode and Effect Analysis, Heavy Equipment Maintenance, Reliability Centred Maintenance, Risk Priority Number.

Abstract

The purpose of this study (a) inventory and identify the composition of amphibians of the Anura order in the Tangkiling Hill Conservation Area, Palangka Raya City; and (b) calculate the ecological index of the Anura order amphibians in the Tangkiling Hill Conservation Area, Palangka Raya City. The results showed that the number of individuals of the amphibians of Anura order found in the research location was 234 individuals consisting of 18 species from 5 families, with the number of amphibian species found in water was 69.23% while in land 30.76%. Based on the calculation of the ecological index, it was found that the value of the species diversity index (H') was around 1.16 – 2.26 which categorized as "low" to "medium". The value of the species evenness index (E') was found to be 0.5 - 0.75, which is included in the "medium" to "high" category. The abundance index value (D) was found to be around 1.41 – 39.66. Meanwhile, the calculation of the important value index obtained an index value around 3.87 – 23.99 with Limnonectes finchi  having the highest value and Bufo juxtasper, Bufo quadriporcatus, Pseudobufo subasper, and Rana chalconota having the lowest value.
