Abstract

Mesin merupakan komponen utama dalam proses produksi, apabila salah satu mesin mengalami kerusakan maka proses produksi akan berpengaruh, target produksi berkurang, dana untuk perbaikan kerusakan tinggi dan pada akhirnya perusahaan mengalami kerugian. Oleh karena itu perlu dilakukan perawatan mesin secara berkelanjutan agar kerusakan mesin dapat diminimalkan dan fasilitas produksi dapat bekerja sebagaimana yang diharapkan. Penelitian ini bertujuan dapat mengetahui performance maintenance yang diterapkan di PT. Kutai Timber Indonesia Particle Board. Penelitian ini menggunakan konsep Total Productive Maintenance dalam menganalisa terjadinya breakdown mesin pada Chiper Area. Nilai Mean Time Between Failure (MTBF) semakin meningkat sejumlah 112.83 menit sehingga peningkatan keandalannya dikatakan baik sedangkan nilai Mean Time To Repair (MTTR) sebesar 13,88 menit hal ini menunjukkan bahwa kemampuan operator maintenance kurang baik. Nilai Availability mesin mengalami peningkatan sebesar 89%. Dengan demikian perlu dilakukan training skill kepada operator maintenance, dikarenakan hasil MTTR yang didapatkan masih tidak stabil,selain itu perlu menerapkan perawatan mandiri atau small repair pada setiap mesin yang di operasikan, Availability mesin perlu ditingkatkan lagi, dengan nilai availability mesin yang lebih tinggi sehingga meningkatkan produktivitas tanpa mengesampingkan faktor-faktor yang lain. Kata Kunci: Maintenance, Mesin, Produktivitas.

Sistem agen yang diterapkan menyebabkan lokasi pick up barang menjadi lebih banyak. Oleh karena itu, optimalisasi penjadwalan rute kendaraan adalah hal yang penting untuk menurunkan kemungkinan barang yang tidak terangkut, menurunkan biaya operasional, dan meningkatkan keuntungan. Tujuan penelitian yaitu melakukan optimalisasi rute pada operator jasa pengiriman barang PT. X dengan mengggunakan pendekatan heuristik. Dua metode heuristik akan digunakan, yaitu metode most valueable neighborhood (MVN-VRP) dan metode nearest neighbor (NN-VRP). Kedua metode tersebut dibandingkan berdasarkan total nilai kargo yang dikumpulkan dan jarak tempuh kendaraan. Hasil penelitian ini menunjukkan bahwa untuk memaksimalkan nilai kargo yang diangkut atau meminimalkan opportunity value yang hilang metode MVN-VRP lebih baik digunakan dibanding dengan metode NN-VRP. Meskipun memiliki jarak tempuh yang lebih panjang, rute MVN-VRP lebih optimal dalam optimalisasi nilai kargo.

Abstract

Pembangkit listrik tenaga uap (PLTU) merupakan salah satu jenis pembangkit listrik yang sering digunakan di Indonesia. Biasanya, komponen utama dari sistem pembangkit listrik tenaga uap meliputi boiler, turbin, generator, dan kondensor. Boiler merupakan komponen utama yang sangat penting dalam sistem pembangkit listrik menggunakan tenaga uap. Boiler adalah bagian yang digunakan untuk mengkonversi air menjadi uap melalui pemanasan. Uap ini akan digunakan sebagai penggerak turbin dan dikonversi menjadi energi listrik sesuai dengan prinsip operasi PLTU. Namun, sering kali terjadi masalah di bagian boiler dengan tingkat kerusakan yang lebih tinggi jika dibandingkan dengan bagian lainnya. Tujuan dari penelitian ini ialah untuk mengajukan strategi yang bisa mengurangi risiko kerusakan pada komponen penting boiler dengan memanfaatkan pendekatan analisis mode FMEA (Failure Mode and Effect Analysis). Pemilihan komponen yang memiliki nilai Risk Priority Number (RPN) tertinggi akan menjadi prioritas dalam usulan pengurangan risiko kerusakan. Failure Mode and Effect Analysis (FMEA) adalah suatu metode penghitungan yang melibatkan penilaian terhadap tingkat keparahan (Severity/S), tingkat kemungkinan terjadinya (Occurrence/O) dan tingkat kemampuan deteksi (Detection/D). RPN terbesar pada Boiler di PLTU PAITON UNIT 9 adalah saat melakukan tindakan pencegahan pada Primary Air Fan dengan skor 140. Dalam hal penggunaan High Speed Diesel, nilai RPN yang terendah yaitu dengan nilai 16. Berdasarkan nilai RPN ini, penulis menyarankan agar peneliti selanjutnya dapat menggabungkan metode FMEA dengan metode pengurangan risiko yang sudah ada untuk mencapai hasil yang lebih efektif dalam mengurangi risiko di masa depan dan digunakan oleh perusahaan.

Abstract

This study aims to minimize inventory costs by implementing a joint replenishment policy on the spare parts inventory system by considering disruption. Analysis was carried out on 11 spare parts related to the effect of disruption on the determination of T, kj and the total costs generated. The results showed that the implementation of joint replenishment policy can reduce inventory costs by up to 21.7%. The effect of disruption in the form of rising material prices affects the increase in total costs linearly. Based on this, companies can choose the right time to order spare parts inventory, so as to avoid excessive storage costs and ordering costs.

Abstract

In a highly competitive market, maintaining high product quality is essential for maintaining customer satisfaction and loyalty. Producers are famous in East Java and face the challenge of ensuring consistent quality products through strict production processes. Know that as easy products broken and soft, needy control of careful quality to meet hope consumers about freshness, texture, and quality in a way whole. Although traditional control methods often fail to overcome the production complex that causes a disabled product. This research proposes integrating Statistical Process Control (SPC), Ishikawa diagrams, and Interpretive Structural Modeling (ISM) to improve control quality. SPC makes it possible to monitor and control production processes in real-time, identify deviations, and repair deviations. However, the SPC limitations include a focus on quantitative data and post-incident detection problems. To overcome root problems, the Ishikawa diagram categorizes the reasons for potency as material, machine, method, power work, and environment. ISM prioritizes action repair based on impact and relationship. Approach This integrated approach provides comprehensive solutions to improve the quality of knowledge. In this study, the control process quality was evaluated using SPC, the cause of defects was identified using Ishikawa diagrams, and priority action repair was performed via ISM. Findings show that SPC directly effectively monitors process control, the Ishikawa diagram identifies main defects, and ISM prioritizes impactful action improvements, emphasizes excessive additions to subtraction materials, and improves health workers’ and mixing process material standards. Approach integrated possible identification of additional problems and improved the quality strategic makes a significant contribution to enhancing product quality knowledge.

Abstract

This research aims to optimize the management of spare parts inventory by considering the level of component damage. To achieve this goal, Reliability Centered Maintenance (RCM), Reliability Centered Spares (RCS), and Economic Order Quantity (EOQ) methods are used. Based on the research results, maintenance intervals were found for each component calculated using the RCM method, and the required amount of spares for one repair period was calculated using the RCS method. The research also calculated the EOQ to determine each component's reorder point, safety stock, optimal order quantity, and total cost. The EOQ calculation results were compared with the total cost before the calculation, and it was found that by using the integration of RCM, RCS, and EOQ, the company can minimize costs of Rp. 2,390,119,- for the 5 analyzed components. Therefore, it can be concluded that the use of RCM, RCS, and EOQ methods can help companies optimize spare part inventory management.
