Abstract

Peternakan ayam H.Mangkuto merupakansalah satupeternakan penghasil limbah yang cukup besar di Lintau Buo dan limbah yang dimaksud adalah kotoran ayam. Limbah jenis ini dapat menyebabkan polusi udara dan akan mengganggu kesehatan manusia tentunya.

Abstract

Maintenance of production machinery is crucial for maintaining the quality of the production process. At PTPN VI Solok, there is a significant issue with the Close Roll Printing Machine, which plays a vital role in the tea pressing process. This study aims to understand the maintenance requirements of the Press Cap Roller Machine and provide maintenance recommendations using the Failure Mode and Effect Analysis (FMEA) and Reliability Centered Maintenance (RCM) methods. FMEA is utilized to examine and track potential failures, while RCM aims to select, develop, and create effective maintenance strategies. The FMEA analysis revealed that the crankshaft is the predominant cause of failure, with a Risk Priority Number (RPN) value of 17.07%. RCM analysis indicated that the Mean Time To Failure (MTTF) for components ranges between 1433.4 and 1811 hours. Recommendations for improvements include checking the crankshaft rotation to ensure it runs smoothly and performing maintenance according to the schedule. Additionally, regular gearbox inspections are crucial, such as checking oil levels, oil circulation conditions, gearbox area leaks, and replacing the gearbox according to the component's lifespan to maintain optimal performance. Other maintenance suggestions involve direct prevention of failure sources and appropriate maintenance, regular bearing replacements and inspections as per the schedule, and routine checks of electrical current and temperature. The implementation of FMEA and RCM methods is expected to provide more structured and effective solutions for maintenance issues, thereby maintaining the quality of the tea production process. This approach also aims to extend the machine's lifespan and reduce unexpected maintenance costs, thus enhancing the company's operational productivity and efficiency.

Abstract

CV. Cahaya  Furniture is an industry engaged in  Furniture, which is located in Kampung Jua, Lubuk Begalung Nan XX District. In the teak cupboard production process, there is an imbalance in the teak cupboard production. This study aims to deterine the performance of the production line balance using the Ranked Positional Weight, Moodie Young, and J-Wagon methods. The results show that the current track efficiency is 76.83%, Balance Delay is 32.17%, Smoothness Index is 36.13 with 5 work stations, whereas after calculating with the Line Balancing method, the result is that using the Ranked Positional Weight method the increased efficiency value increased to 96.04%, the balance delay decreased to 3.96%, the smoothness index was 5.32 with withdrawals being 4 work stations. In the Moodie Young method, the recovery efficiency value is the same as the initial condition, which is 76.83%, the balance delay is 23.17%, the smoothness index is 14.39 with 5 work stations. In the J-Wagon method, the track efficiency value decreased to 64.03%, the balance delay increased to 35.97%, the smoothness index was 19.65 with 6 work stations. The results of this study indicate that the most effective method used is the Ranked Positional Weight method because there is a reduction in work stations to 4, and increases transfer efficiency to 96,04%, decreases balance delay from 3.96%, and smoothness index decreases to 5.32.
