In the production process, there are still various indications of waste that cause a decrease in the efficiency and effectiveness of the production process. One of the biggest problems is defects, with a percentage of defects above 5%. Therefore, it is necessary to optimize the process of the crankcase to increase the effectiveness and efficiency of production. This study aims to eliminate waste in the production line of the crankcase by implementing the lean manufacturing concept. The lean manufacturing method used is the Waste Assessment Model (WAM) to distinguish waste in the manufacturing process. The integrated cost value stream introduces cost lines that can help facilitate decision-making. Based on the results of waste identification, the 3 largest wastes were found, namely defects, inventory, and transportation. There are 2 alternative improvements to overcome this waste, namely by changing the jig tool and changing the push-to-pull method. The results show that defect waste decreased to an average of 4.8%, the total value added cost decreased by 1%, total non-value added cost decreased by 55%.","PeriodicalId":178760,"journal":{"name":"Proceedings of the 2022 International Conference on Engineering and Information Technology for Sustainable Industry","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128292176","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}

XYZ Pharmacy, which is located in the Jakarta area, is one of the industrial companies engaged in Health Services and focuses on the skin and genital area. The need for planning the number of purchases of medicinal products for Inventory at XYZ Pharmacy is very important. It was found that there were problems with the company, namely experiencing a very large amount of stock and decreasing stock in supplement products so that many products expired and lost customer trust. The purpose of this study was to determine the number of drug purchases at XYZ Pharmacy to reduce decreasing or excess drug stock. The method used in this study is the Fuzzy Sugeno and Fuzzy Mamdani method. The application of the Fuzzy Sugeno and Fuzzy Mamdani methods uses three variables, namely: the number of inventories, the number of sales, and the number of drug purchases with the help of MATLAB software. Determination of safety stock and reorder points conducted by XYZ Pharmacy is carried out to minimize inventory running out which has an impact on customer satisfaction levels. The results of this study are In Fuzzy Mamdani's calculation, the Enervon C Tab Strip 4S/25 STRP product has a fulfilled presentation result of 79%. In Fuzzy Sugeno's calculation, the Enervon C Tab Strip 4S/25 STRP product has a fulfilled presentation result of 31%.

This emulsion is stabilized by oleophilic nanoparticles without the need of surfactants. However, finding an oil with cheap and easily available to create an emulsion is not easy. This paper introduces the trial blend of W/O emulsions with a very common material, namely used engine lubricant oil. More than one billion liters of engine lubricant oil are used in Indonesia every year and has become a major contributor to pollution due to improper use at its disposal. In other ways, this used engine lubricant oil can be an excellent candidate for making emulsions W/O. First, the detergents, the acidity and soot (organic carbon) from the decomposition of engine oil lubricants provides perfect solid particles to stabilize the emulsion; secondly, the medium viscosity allows optimal viscosity to be achieved when blending the emulsion; and the third, nanoparticles from oxidized wear metal from engine debris can help also to reduce the IFT of heavy oil.","PeriodicalId":178760,"journal":{"name":"Proceedings of the 2022 International Conference on Engineering and Information Technology for Sustainable Industry","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115814743","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}

Nickel matte is an important raw material in producing the producing electric cars. The precision and speed with which the kind of laterite nickel ore is determined based on the olivine concentration are critical because it affects energy requirements and nickel recovery. The present challenge is that it takes a long time to obtain the Loss on Ignition (LoI) number, which will be used to calculate the olivine concentration. As a result, an alternate approach for determining the type of ore without going through the phases of assessing the LoI value is required. The k-means clustering method examined data from one of the blocks in the PT Vale Indonesia Tbk mining region. The K-Means method is used to cluster data from 9 chemical elements. The olivine group that will be produced as a result of this analysis is characterized by three scenarios: the first one is the olivine group using two clusters according to the present split of olivine groups, namely high olivine and low olivine. The second scenario employs three clusters: high olivine, medium olivine, and low olivine. The third scenario uses four clusters based on the elbow method and silhouette guidelines. According to the findings, the best number of clusters was two clusters. The level of accuracy for 2 clusters, when compared with the conventional method, achieved 97.9% for cluster 1 and 85.0% for cluster 2.","PeriodicalId":178760,"journal":{"name":"Proceedings of the 2022 International Conference on Engineering and Information Technology for Sustainable Industry","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122431869","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}

This study seeks to develop a customer loyalty model by considering several factors that influence loyalty such as customer satisfaction, loyalty programs, corporate image, service recovery, perceived safety, price, and service quality. In addition, the effect of differences in the purpose of using the shuttle service was tested on the customer loyalty model. The sample of 384 respondents who have used shuttle services in the last 12 months were used in this study. Sample were divided into two groups, customer for business/college/school purpose and for vacations purpose. Data analysis is performed using multigroup SEM analysis. The SEM results of both of the group show that the absolute fit of the model is adequate judging by the RMSEA value of 0,062 and 0,063 respectively for each group. CFI and TLI which were used as the incremental fit also reach the value of more than 0,9 for both groups which indicate a good incremental fit. Furthermore, from the results showed that there was a significant moderating effect of the difference in the purpose of using the shuttle service on the customer loyalty model. In the group with business/college/school goals, safety perception has no effect on customer satisfaction and company image has no effect on customer loyalty. Customer satisfaction in this group is proven to influence customer loyalty, but the relationship is not stronger than the group with the purpose of using the shuttle service for vacations. In the group with vacation destinations, the perception of safety influences customer satisfaction, but company image has no effect on customer loyalty. Customer satisfaction in this group is proven to influence customer loyalty with a stronger tendency compared to the other group.","PeriodicalId":178760,"journal":{"name":"Proceedings of the 2022 International Conference on Engineering and Information Technology for Sustainable Industry","volume":"11 10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116816643","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}
