In order for supply chain to be competitive in competition, delivery time is an important factor to manage, so that it could provide high service level value. One factor that could affects distribution or delivery is distribution center location. A strategic distribution center location would facilitate and speed up distribution process. This research discusses model for determining location of distribution center so that delivery could be made at the right amount and in the right time by analyzing of time-based using set covering model and maximal covering model. The numerical example in this research is case study on paint supply chain in Bandung which has a number of delivering clusters. Each cluster consists of a number of building material stores which are located scattered. There is one cluster that has problems in fulfilling demands and delivery times. The analysis made could be used to determine the distribution center location so that it could serve all consumer demands. Based on the calculation results, it was found that there were two distribution center locations. Two distribution centers could fulfill the objective function of cost minimization and satisfy all demands. The results of the sensitivity analysis show that there are several factors that influence the determination of location number.","PeriodicalId":34167,"journal":{"name":"OPSI","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46092930","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 is Dam “X”. Based on project management data obtained from PT. XYZ, the actual project construction process experienced a significant delay from the planned schedule, with a delay duration of approximately 30 days. The delay will have an impact on the duration of the final completion of the project, including the process of delivering project results to consumers. The purpose of this study is to determine the critical path in project implementation and identify activities that do not have slack time because it will affect the duration of the overall project completion. The method used in this study is the Critical Path Method (CPM), which is a network method consisting of a series of activity components with the longest total time and showing the fastest duration of project completion. The results showed that the Manufacturing Project has a total of 11 critical activities out of 37 activities (work packages), with a total critical time of 75 days. The total critical time from the calculation of the CPM method also shows the optimal total project duration which can be used as a reference for the project team for the completion of a fabrication project or a hydromechanical component installation project on Dam \"X\".","PeriodicalId":34167,"journal":{"name":"OPSI","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44602795","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}

For this reason, a study was conducted to determine the factors influencing the purchasing intention of environmentally friendly diapers. The factors studied included attitudes, subjective norms (SN), perceptions of behavioral control (PBC), environmental awareness (PL), moral responsibility (Norm), and perceived risk (PR). These six factors will be tested to determine whether they significantly influence the intention to use cloth diapers, then their effect will be analyzed. The objects in this study are residents of the City of Yogyakarta who have and take care of infants or toddlers. Data was obtained by distributing questionnaires. Data processing begins with validity and reliability testing. After testing the validity and reliability, it is followed by regression tests, model significance, significance test for the influence of each independent variable, and finally, determining the coefficient of determination. From the processing of the 406 questionnaires, it is known that three variables significantly influence: subjective norms, perceptions of behavioral control, and moral responsibility. The resulting regression equation is Intention=0.045attitude+0.288 SN+0.277PBC+0.009PL-0.020PR+0.316Norm. The coefficient of determination of the conceptual model is 64.2%, which means that changes in the values of the six variables studied contribute to a variation in the response variable (intention) of 64.2%.","PeriodicalId":34167,"journal":{"name":"OPSI","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47737550","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}

However, K3 at PT XYZ, especially in the production process, is still not going well according to the law, one of which is the use of PPE is considered not important by the workforce. This study aims to analyze the risks and controls in the production process. This research was conducted by identifying potential hazards by categorizing them into risk levels and determining the control of potential hazards in the production process using the HIRADC method. The results of this study indicate that there are 9 risks in the production division, with the grouping of 5 risks classified as high risk (high) which includes high risks such as bandsaw regarding sawdust, assembly, 1 moderate risk (moderate) risk, namely the raw material part, and 3 the risk is classified as low risk (low) which includes low risk such as band saw machines for chop saws. Based on the results of the risk assessment, most machines are classified as high risk, so it is necessary to improve the implementation of K3 and improve the source of danger. Of all the hazards and risks in the production division of PT XYZ, an analysis of potential hazards and their control is carried out using the HIRADC method. The recommendations given include completing PPE, carrying out engineering for example, carrying out eliminations such as using dust powder covers and using push sticks.","PeriodicalId":34167,"journal":{"name":"OPSI","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49495264","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}
