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

Sus Tenun Lintau (STL) is an MSME that produces woven clothing materials, detta, and scarves. The most popular at the moment is detta. In order to compete in the market, STL sets high standards by using an effective and efficient production system. The accuracy of homogeneous products must have the same character. From the background, this study analyzes the quality of STL production results. This study uses capability process analysis. capability process can identify the quality of production (product nonconformity) produced, analyze the capability of the production quality process and control the quality of production results. The results of processing, interpretation of dimensional characteristic data are spread following a normal distribution while the control limits indicate that the dimensional characteristics of the detta product variables are in control. From the results of the Capability Process calculation, the process capability (Cp) can be analyzed, the value of 1.00 <Cp <1.33 and the characteristic value of Cp = Cpk, this means that the process is centered in the middle between the specification limits. The result is that the production capability (process capability) of each product size dimension has good results
