Abstract

Product planning, design, and development are essential phases in manufacturing, starting from conceptualization and system design to production, testing, and ultimately delivering superior products that meet consumer demands. For instance, in the oil palm plantation industry, efficient tools play a vital role. Harvesting significantly affects the quality of oil palm yields, with losses often occurring due to loose fruit detachment from the Fresh Fruit Bunches (FFB), which fall to the ground. These loose fruits, known as "berondolan," are just as valuable as those still attached to the FFB and contribute substantially to farmers' income. Currently, farmers must manually collect these fallen fruits from beneath each tree, which is time-consuming. To address this issue, the study introduces a harvesting tool designed through reverse engineering for gathering loose oil palm fruits. After processing and analysis, the proposed tool incorporates modifications, particularly in the roller section, where two 10 cm diameter stainless steel drain holes are added. Additionally, it features two 6.5 cm diameter iron drives, enhancing efficiency by increasing collection capacity by 1.5 kg per minute compared to conventional drain hole designs. Keywords: Brondolam, Design, Efficient, Palm fruit collection tool, Oil Palm, Reverse engineering.

Abstract

Recurrent failures of the arm cylinder on the Kobelco SK 200-10 excavator at PT. XZ have resulted in increased downtime, decreased equipment performance, and higher maintenance costs. This study aims to evaluate equipment effectiveness through the implementation of Total Productive Maintenance (TPM) using the Overall Equipment Effectiveness (OEE) method. Measurement results for the period September–December 2024 indicate an OEE value of 38.97%, with availability of 82%, performance of 50.46%, and quality of 93.75%, suggesting that the equipment performance remains suboptimal, particularly in terms of performance . Six Big Losses analysis reveals that the largest losses are caused by reduced speed losses at 52.08% and average equipment failure losses of 13.96%. The main contributing factors are identified as machinery conditions, work methods, environmental factors, and operator involvement. Therefore, improving equipment effectiveness can be achieved through more disciplined preventive maintenance, refinement of operating procedures, and increased operator participation in daily maintenance activities. Keywords: Kobelco SK 200-10, OEE, Six Big Losses, TPM

Abstract

CV. X frequently experiences recurring failures in Cummins genset components, such as rubber coupling, fuel filter, oil filter, battery, and radiator. This condition causes considerable downtime and increased maintenance costs, as the maintenance approach remains reactive. This research aims to design a more effective maintenance strategy using the Reliability Centered Maintenance (RCM) method. Data were collected through observation, interviews, and failure history records, then analyzed using Failure Mode and Effect Analysis (FMEA) to identify critical components, as well as Logic Tree Analysis (LTA) to determine the appropriate maintenance strategy. The results revealed five critical components, with the highest risk value found in the rubber coupling(RPN 300). The recommended strategy is Condition Directed for the rubber coupling, battery, and radiator, and Time Directed for the fuel filter and oil filter. Implementing this strategy is expected to reduce downtime and improve machine reliability. Keywords: Cummins Genset, Downtime, Logic Tree Analysis (LTA), Maintenance, RCM
