Abstract

The Ripple Mill machine is one of the vital components in a Palm Oil Mill (PKS) that functions to separate the palm kernel from its shell. This process is very important because the quality and quantity of the palm kernel produced will directly affect the economic value and production efficiency in the palm oil industry. At PTPN IV Regional II Plantation Unit and Adolina PKS, various technical problems were found that caused a decrease in machine performance, including rotor bars and square bars that experienced wear due to age and improper machine settings. In addition, other damage that often occurs is a broken van belt due to age and excessive tension, feeder motor dysfunction caused by excessive load, and motor overheating that occurs due to age and high workload. To overcome these problems, this study uses the Failure Mode and Effect Analysis (FMEA) method. This method aims to identify various potential failures, assess the severity, frequency of occurrence, and detection capability, so that the Risk Priority Number (RPN) value can be calculated as a basis for repair priorities. The results showed that worn rotor bars and worn square bars had the highest RPN values, each at 280, equivalent to 40.23% of the total identified risks. This indicates that these two components are critical points requiring immediate repair and maintenance attention. Applying FMEA in this context provides tangible benefits, including helping the company formulate a more targeted maintenance strategy, reducing the risk of recurring damage, and minimizing downtime that impacts production. With more systematic maintenance, operational efficiency can be improved while extending the lifespan of the Ripple Mill machine.

Abstract

Persediaan adalah salah satu persyaratan utama yang harus dipenuhi dan dimiliki oleh bisnis dalam aktivitas perdagangannya, karena persediaan merupakan tempat transaksi dilakukan. Manajemen persediaan yang kurang baik juga bisa jadi dikarenakan para pelaku usaha yang masa bodoh dan acuh terhadap bagaimana mengelola persediaannya karena beranggapan bahwa yang penting usahanya dapat terus berjalan tanpa tahu sewaktu-waktu usahanya harus tutup karena semakin banyak persediaan yang tidak terjual karena habis masa layak pakainya. CV. Cikini Raya merupakan salah satu usaha yang menyediakan jasa konstruksi di kota Medan. CV. Cikini Raya sendiri dalam memenuhi kebutuhan semen, melakukan pemesanan dengan melihat persediaan bahan baku yang akan habis dan mengakibatkan proses produksi menjadi terhambat. Berdasarkan kondisi tersebut penulis tertarik untuk melakukan kajian ataupun analisis terhadap manajemen persediaan dari CV. Cikini Raya. Jenis penelitian ini merupakan penelitian deskriptif analitik. Hasil dari penelitian ini adalah peramalan terhadap pemakaian semen untuk 48 minggu selanjunya.

Abstract

Machine effectiveness is a critical factor in ensuring smooth operations within the palm oil processing industry. One of the most vital machines in this process is the sterilizer, which functions to deactivate enzymes, soften fruit, and facilitate the detachment of fruit bunches. This study aims to evaluate the effectiveness level of the sterilizer machine at PT. Tri Cahaya Sawit using the Overall Equipment Effectiveness (OEE) method and to propose an improvement strategy based on Total Productive Maintenance (TPM). This research adopts a quantitative case study approach with descriptive analysis. Data were collected through direct observation, interviews, and company documentation from March to June 2024. The three OEE parameters analyzed include availability, performance, and quality rate. The results showed an average OEE value of 82.5%, with an availability rate of 92.67%, performance rate of 91.87%, and quality rate of 97.43%. These figures remain below the world-class OEE benchmark of 85%. The primary factors contributing to low effectiveness were high downtime and suboptimal maintenance scheduling. Fishbone diagram analysis revealed that the dominant causes included reactive maintenance practices, lack of operator training, and inadequate maintenance documentation. Therefore, the implementation of the eight TPM pillars—particularly autonomous maintenance and planned maintenance—is proposed to enhance the reliability and efficiency of the sterilizer machine. This study concludes that OEE serves as an effective evaluation tool to identify operational losses, and a structured TPM implementation can significantly improve machine performance and overall company productivity. Keywords: Total Productive Maintenance, Overall Equipment Effectiveness, Sterilizer Machine, Downtime, Productivity.

Abstract

This study aims to analyze the implementation of Reliability Centered Maintenance (RCM) in the maintenance of crane machines at PT Pelindo. Cranes play a vital role in port loading and unloading activities, making operational reliability essential for smooth logistics operations. The RCM approach is used to identify critical components based on potential failures, their impact on operations, and the effectiveness of maintenance actions. Data were collected through observation, interviews, documentation, and questionnaires, and analyzed using Failure Mode Effect Analysis (FMEA), Mean Time Between Failure (MTBF), Mean Time To Repair (MTTR), and Availability. The results indicate that components such as the contactor, carbon collector, and motor hoist/gearbox have the highest Risk Priority Number (RPN), requiring prioritized maintenance. The MTBF value of 317.687 hours reflects a relatively high level of machine reliability, while the MTTR of 3.25 hours demonstrates repair efficiency. The implementation of RCM has proven effective in improving reliability, reducing downtime, and minimizing maintenance costs. The study recommends enhancing preventive and predictive maintenance, as well as training technicians to efficiently detect and manage failures. Keywords: Reliability Centered Maintenance, crane, maintenance, FMEA, MTBF, MTTR
