Abstract

Maintenance emerges as a crucial intervention to ensure the sustained reliability of machinery. The AMC 36-800/MA AN SHAN lathe, a piece of equipment subject to extensive operational demands, frequently encounters breakdowns, thereby obstructing the seamless execution of maintenance activities for facilities. This investigation seeks to pinpoint the components responsible for the failures and malfunctions afflicting the lathe above. Employing the methodologies of Failure Mode and Effects Analysis (FMEA) and Fault Tree Analysis (FTA), this study successfully identifies the components at the epicentre of the machine's vulnerabilities. The analysis culminates in delineating critical components by calculating Risk Priority Numbers (RPN), unveiling a pivotal RPN value of 309.57. Moreover, it isolates two components whose failure modes surpass the critical RPN threshold: the Drive Motor and the Fixed Head. The genesis of these failures can be attributed to the escalating operational intensity, elevated engine temperatures, and a maintenance regimen that is both sporadically scheduled and suboptimal. Keywords: Lathe AMC 36-800/Ma AN Shan, Failure mode, FMEA, FTA, RPN

Abstract

UKM Gudang Dompet is a company that produces wallets. The number of orders will affect employee performance because the number of targets achieved will increase the workload for employees, causing fatigue. To prevent excessive fatigue felt by workers in the production division at the Dompet Warehouse, it is necessary to measure workload. The Full Time Equivalent (FTE) method measures working time, which is based on working time, measuring the time needed to complete a particular task and then converting it into an FTE index value. The cardiovascular load (CVL) method measures physical workload based on comparing pulses. Working pulse with a maximum pulse. This research showed that worker fatigue occurred in the packing section, indicated by a CVL value of more than 30%, so FTE calculations were carried out to determine energy consumption. Based on energy consumption calculations, the results obtained are an additional rest time of 32.85 minutes in the packing section. Keywords: workloads; full-time equivalent; CVL; work system design.

Abstract

XYZ Company, a Micro, Small, and Medium Enterprise (MSME) based in Yogyakarta, specializes in producing hijabs but faces challenges in maintaining customer interest due to a misalignment between product designs and consumer preferences. To address this, the company actively engages in new product development (NPD), focusing on trend analysis and model innovation to cater to customer needs better. An essential part of minimizing risks during the NPD process involves evaluating and identifying potential pitfalls, particularly in marketing and design. This study employs the Hazard and Operability Review (HOR) method to assess risks systematically. Initial findings from HOR phase 1 reveal that inadequate competitor information (A3) leads to significant risks in competitor product identification (E3), contributing approximately 70.34% to the total Aggregate Risk Priority (ARP). Subsequently, in HOR phase 2, XYZ Company prioritizes ten mitigation actions, with conducting a comparative study of competitors' products (PA1) being the most critical, reflected by an ETDk value of 540. Keywords: House of Risk (HOR), Hijab Fashion, Hijab Industry, New Product Development (NPD)

Abstract

Ant-sugar SMEs are developing in the Indragiri Hilir Regency. This industry uses the sap of hybrid coconut trees to make sugar. To maintain sustainability, SMEs require assistance with quality from upstream to downstream. Based on this, the research attempts to ascertain the mechanism of the sugar supply chain, identify the elements that lead to flaws, and suggest ways to enhance the chain's quality. Identify supply chain conditions using the Vorst method and identify the root causes of problems using the FTA method and quality improvement proposals based on evaluating potential failure levels using the FMEA method. The research results show that the supply chain members are Farmers, SMEs and Final Consumers. The factors causing defects in coconut sap water and ant sugar are human and environmental. The proposed improvement at the farmer level is that the cracked wood preservative must be measured correctly before taking coconut sap water. In contrast, at the SME level, workers pay attention to the ongoing production process and carry out periodic checks when boiling the sap water so that the maturity level is perfect and stir optimally so as not to cause failure. In the crystallization of ant sugar.
