SPPA is still carried out conventionally, especially in the idler rebuilding process. There are found work accidents that result in work-related illnesses. In preventing accidents, it is necessary to do risk management efforts. Therefore it is necessary to conduct research by integrating FMEA and TOPSIS for risk management strategies in Occupational Health and Safety (OHS). The FMEA method is used to identify risks and assess the level of risk based on severity, ooccurrence and detection. Furthermore, the TOPSIS method is used to determine the order of priority for improvement to overcome existing risks. The results showed that there were 17 risks in machining activities with a lathe where the risks with the highest RPN value were experiencing pain or muscle cramps when setting up the lathe, experiencing noise during the lathe process, and exposure to chips from the lathe process. Furthermore, each risk is investigated using the 5 Whys method to determine the root causes of the problems, and it was found that the causes of these risks were low-quality work equipment, lack of training, socialization or briefings on OHS, and the high cost of providing adequate PPE. Based on these issues, a priority list of recommendations for improvement is compiled using the TOPSIS method, including routine equipment condition checks, providing SOPs for equipment use, providing appropriate PPE for each job, providing training for employees, allowing adequate rest time, and providing high-quality work equipment.","PeriodicalId":345326,"journal":{"name":"Operations Excellence: Journal of Applied Industrial Engineering","volume":"2012 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139351669","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A B C. However, many challenges were encountered in the commercialization of the converter kit from PT ABC, such as limited and uncertain suppliers, limited introduction to the market, and unpreparedness of Human Resources in product management. This study aims to analyze the constraints on the commercialization process of converter kit products as a basis for designing supply chain engineering proposals and appropriate business engineering. Based on the analysis of TRL and Goldsmith, it shows that the product is at TRL 8 or has fulfilled the requirements, but still has various obstacles. Based on the SWOT analysis, the company still has several shortcomings due to limited market interest, marketing strategies implemented, and price volatility. The results show that there is a business strategy design using the Business Model Canvas method to accelerate technology commercialization, one of which is through the expansion of existing partnership and marketing systems.","PeriodicalId":345326,"journal":{"name":"Operations Excellence: Journal of Applied Industrial Engineering","volume":"30 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139351624","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Components on aircraft have a high enough price that maintenance is required. The power source on an airplane can be divided into 2 types, namely AC and DC. One source of AC electricity is the Integrated Drive Generator (IDG) which is one of the important components of an aircraft that functions as a generator of electricity. If IDG experiences a problem, it will disrupt aircraft operations. For this purpose, IDG must receive good care with effective services. The processing time for maintenance services takes 42.8 hours for one IDG part unit. This study aims to balance the trajectory. The IDG part maintenance process is carried out by Pro-model simulation. The results of the IDG maintenance simulation are the maintenance time in operation (Average time in Operation) which is 42.61 hours and the IDG parts handled are 11 IDG parts. The results of this simulation scenario can estimate the possible number of IDG parts that will occur annually and can estimate the total service capacity that handles the planned number of incoming entities. The best scenario results when the capacity of 1 service group per unit will result in the number of IDG maintenance services of 11 units per year, by increasing the service capacity to 2 service groups per unit will result in the number of IDG maintenance services of 23 units per year. And by increasing the service capacity to 4 service groups per unit, the number of maintenance services will be 46 units per year.","PeriodicalId":345326,"journal":{"name":"Operations Excellence: Journal of Applied Industrial Engineering","volume":"40 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139351627","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The defects that arise occur because the composition of injection molding parameter values is not optimal in the variables of melt temperature, mold temperature, packing time, packing pressure, and cooling time. The purpose of this study is to find the optimal composition of parameter values for each variable, to minimize sink mark defects in the product. The analysis process begins with the preparation of an orthogonal array matrix to determine the design parameters to be simulated on Autodesk mold flow. These results are evaluated with a signal-to-noise ratio to determine the effect of each parameter value composition on the results of the analysis process. The Analysis of Variance (ANOVA) method is used to estimate the contribution of each independent variable to all response measurements (the dependent variable). The optimization results for sink mark defects in the sink mark index value of 1.4494%, volumetric shrinkage of 0.5053%, and sink mark estimate of 0.0608 mm are found in the composition of the parameter values of melt temperature 200°C, mold temperature 80°C, packing time 30 seconds, packing pressure 80 MPa and a cooling time of 13,365 seconds.

As a result, it leads to an increase in inventory costs and even a loss of sales. The solution offered by this study is an optimization of production planning, namely determining what products and how many of these products should be produced in a certain period. The method used is goal programming, both with and without priority, so that Mahkota Caman can meet consumer demands, and minimize production costs, while minimizing the purchase of raw materials. The results of this study indicate that the optimal optimization method used by Mahkota Caman is goal programming with priority because it provides a more efficient solution to production costs and the purchase of raw materials. Based on the results of this study, it is recommended that optimization methods be used by MSMEs in the food and beverage sector during a pandemic, and to avoid using only feeling in production planning.","PeriodicalId":345326,"journal":{"name":"Operations Excellence: Journal of Applied Industrial Engineering","volume":"24 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139351639","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
