Abstract

This study aims to analyze sansivera fiber-reinforced composite materials with a polyester resin matrix and treat sansivera fibers against alkaline NaOH liquids with levels of 4%,7%,10%,13% and 15%.in this study for experimental design using the hand lay-up method,which aims to analyze experimental data,and is also used to determine the minimum number of experiments that can be obtained and provide infotmation on factors that influence parameters.The experiments were carried out through 1)composite manufacturing method,2)immersion with alkaline NaOH,3)fiber tensile test method,4)microstructure test method,5)composite tensile test methods.the results of research on tensile test of fibers from the soaking process with alkaline NaOH 4%,7%,10%,13% and 15%,get the best results in the 15% NaOH alkaline immersion process. From results of the tensile test the fibers will be formed into 7 composite specimens, from the composite tensile test the maximum tensile strength is obtained on specimen 5 with 40% treatment of 45,71 N/mm2 and the highest elongation obtained on specimen 4 with 30% treatment of 3,95mm.

Abstract

This study investigates a food manufacturing firm's efforts to enhance operational efficiency by optimizing its maintenance strategy and spare parts management within the context of noodle production. The research focuses on reducing prolonged machine downtimes caused by boiler malfunctions, which negatively impact production targets. A novel approach combining total minimum downtime calculations and a hybrid corrective-preventive maintenance methodology has been proposed. To bolster this initiative, an efficient spare parts procurement scheme was implemented. Results demonstrate a substantial reduction in unplanned downtime following implementation, thereby improving overall productivity and profitability. Implications highlight the potential for widespread application across similar industries seeking to minimize disruptions while maximizing equipment lifetimes. highlight : Reduced downtime through improved boiler maintenance. Hybrid corrective-preventive maintenance for efficient operations. Optimized spare parts procurement for enhanced productivity. Keywords: noodle production, boiler maintenance, downtime reduction, spare parts management, hybrid maintenance.

Abstract

This study investigates the risk levels and potential for work accidents in manufacturing processes involving heavy equipment like lathes, which often lead to accidents due to non-compliance with safety regulations. Employing job safety analysis (JSA), the research aims to minimize accidents by assessing risk levels and proposing comprehensive Personal Protective Equipment (PPE) usage for workers. Results reveal that the welding process's failure mode severity is rated at 2, while lathe-related accidents, particularly exposure to debris, have the highest occurrence and effect analysis at 6. Limited PPE availability contributes to a low failure mode detection and effect analysis score of 7. This study underscores the critical need for implementing stringent safety measures to mitigate workplace accidents in manufacturing settings. Highlights : Comprehensive assessment: Utilizing job safety analysis (JSA), the study provides a detailed evaluation of potential work accidents in manufacturing processes, focusing on heavy equipment usage. Risk mitigation: The research emphasizes the importance of implementing stringent safety measures, including the complete utilization of Personal Protective Equipment (PPE), to minimize the occurrence of workplace accidents. Importance of compliance: Non-compliance with safety regulations, particularly regarding the use of PPE and adherence to K3 regulations, significantly increases the risk of work accidents, leading to disruptions in production processes. Keywords: Workplace Safety, Manufacturing, Job Safety Analysis, Personal Protective Equipment, Risk Assessment

Abstract

In the realm of backup power sources, maintaining the efficiency of generators is paramount for ensuring reliability and availability during power outages. This study aims to evaluate generator efficiency through routine maintenance analysis, adhering to regulatory frameworks outlined in regulations such as Regulation No. 29 of 2012 and Electricity Law No. 30 of 2009. By employing methods including Mean Time Between Failures (MTBF) and assessing Actual Operating Time (AOT) against Specified Operating Time (SOT), this research determines the availability and compliance of each generator. Results highlight the importance of stringent regulatory compliance in enhancing the functionality and reliability of generators, thereby emphasizing the significance of routine maintenance for improved operational health. Highlight : Adherence to regulatory frameworks ensures operational compliance and reliability. Routine maintenance analysis enhances generator efficiency and availability. Availability assessment methods such as MTBF and AOT provide insights into operational health. Keywords: Generator reliability, Routine maintenance, Regulatory compliance, Availability assessment, Backup power sources
