Abstract

This research is propose the replacement schedule of a critical part of a critical machine in a the clove line of PT. Hanjaya Mandala Sampoerna Tbk. From the direct observation, the screw conditioning process is the critical process of the the tobacco production in clove line. One of the screw conditioner, Garbuio Dickinson screw conditioner, was observed as the machine with the most downtime in clove line. Further analysis using chart reveals that the motor screw conditioner is the main problem to the machine breakdown. Index of fit calculations were applied to find the time to failure and time to repair distribution by looking at the highest index of fit of each failure distribution. Maximum Likelihood Estimator step was undergone to find the MTTF and MTTR (in hours) for the chosen distribution. Finally, the best time interval to replace the critical part in order to increase the component reliability and machine availability was calculated. Result of this preventive replacement is increases the component reliability by 80% and the machine availability by 0.245%.

Abstract

This study uses moving average and exponential smoothing methods to predict the demand for Raskin rice in Banda Aceh. The Logistics Agency (Bulog) is a food institution in Indonesia that organizes a rice trading system, which functions to provide rice distribution services to the public. The fluctuation in demand for Raskin rice in Banda Aceh makes it difficult for Bulog to predict future needs. In addition, the excess supply of Raskin rice will also be very detrimental because rice is a staple that is perishable. Therefore, it is necessary to conduct research to predict the demand for Raskin rice in Banda Aceh. The results of forecasting or prediction by comparing two methods and three errors in forecasting accuracy, it can be concluded that the exponential smoothing method with α = 0.90 can be used to predict the demand for Raskin rice in Banda Aceh City. The prediction result of the demand for raskin rice in Banda Aceh is 92,407 tons, with an MAD error rate of 4.92, MSE 34.58, and MAPE 0.006%, or having the smallest value compared to the 7-month moving average method.

Abstract

Panas matahari yang diserap oleh modul surya dapat menaikkan suhu dan menurunkan tegangan keluarannya. Upaya penurunan suhu modul surya agar dalam kondisi standar diperlukan untuk menjaga agar kinerjanya tetap optimal. Pemasangan bahan penyerap panas seperti heatsink merupakan salah satu metode yang dapat digunakan sebagai upaya mendinginkan modul surya. Heatsink mampu mengurangi suhu rata-rata modul surya hingga 2,43°C dan meningkatkan tegangan keluaran rata-rata modul surya hingga 2,23 Volt. Kondisi ini dapat dilihat dari rata-rata tegangan output Voc modul surya yang ditambahkan heatsink dapat mencapai tegangan rata- rata 20,76 Volt dibandingkan dengan modul tanpa penambahan heatsink 18,52 Volt. Disimpulkan bahwa penambahan bahan penyerap panas berupa heatsink lebih efektif menurunkan suhu modul surya dari pada tanpa menggunakan heatsink.

Abstract

CV. Rasya Jaya is a traditional fishing boat manufacturing company located in Padang Seurahet, Kec. Johan Pahlawan, Aceh Barat Regency. The facility layout of CV. Rasya Jaya has several workstations that are not in the correct location for the production process or the relationship between related rooms. This results in inefficient and ineffective material handling, as well as reduced worker comfort. The poorly organized facilities also contribute to production constraints. Therefore, it is necessary to evaluate the production facility layout at CV. Rasya Jaya. The goal is to provide an alternative design for the production facility layout that is more efficient and effective in terms of the relationship between the production process flow and minimizing material flow in the production process. The purpose of this study is to determine the optimal layout at CV. Rasya Jaya using the Blocplan algorithm. Blocplan-90 is an algorithm for solving spatial layout problems that can handle both quantitative and qualitative data. Mathematical models within the design are developed with computer applications for models that work with the limitations of workstation shapes. Based on the results of the layout design of facilities at CV. Rasya Jaya, three main layouts were created: office layout, facility layout, and production layout. The total area of the three layouts is 1739 m2.

Abstract

The existence of a Regional Drinking Water Company (PDAM) is very important in maintaining the continuity of the clean water treatment process running smoothly and well. Maintenance of clean water distribution machines and equipment is a matter that requires attention because damage to one of the machines or equipment can cause a cessation of processing activities which results in losses for companies and services. Damage to the water distribution machine in PDAM Tirta Mountala is unavoidable and this happens frequently. This happens because the damage is not properly identified, either in preventive maintenance or in anticipating appropriate action. The purpose of this study is to identify the cause of the damage and propose maintenance actions on the clean water distribution pump machine in PDAM Tirta Montala Aceh Besar. The failure mode and effect analysis (FMEA) and logic tree analysis (LTA) approaches are used to anticipate this. FMEA is an approach used to identify and analyze potential failures and their consequences. Meanwhile, LTA aims to prioritize each damage mode and carry out reviews and functions, malfunctions so that the damage mode status is not the same. There are eighteen water distribution pump components with the highest damage frequency. Based on the results of the FMEA, five components with the highest RPN or the highest risk were obtained, namely the vane, stuffing box, bearing bracket support, shaft and bearing components. The five components were then analyzed through LTA and maintenance tasks with several proposed actions including repair, component replacement, welding, thermography, and re-measurement with a vibration meter.

Abstract

This research aims to analyze the financial feasibility and sensitivity of investment in the rejuvenation of smallholder oil palm plantations in Lungmane Village, Kuala Pesisir Subdistrict, Nagan Raya Regency, Aceh Province, amidst the problem of declining Fresh Fruit Bunch (FFB) productivity due to aging trees. The research method used is quantitative analysis with investment criteria of Net Present Value (NPV), Internal Rate of Return (IRR), Net Benefit-Cost Ratio (Net B/C), and Payback Period (PP), as well as sensitivity analysis to changes in FFB prices. The results of the analysis show that the rejuvenation project for smallholder oil palm plantations in Lungmane Village is financially feasible based on positive NPV, IRR, Net B/C, and Payback Period indicators. However, the sensitivity analysis reveals that the project's feasibility is highly influenced by fluctuations in FFB prices, where a price decrease of up to 70% can render the project unfeasible. This study concludes that although the rejuvenation of smallholder oil palm plantations in Lungmane Village has good financial prospects, farmers need to be aware of the risk of declining FFB prices.
