Case study at the Human Resources Department of a publishing company show that there is a problem with the compensation system that is felt to be unfair. The existing method used in the company was job classification without considering workload. Therefore, it is important to determine the job relative value as a reference for designing compensation. This study compared two job evaluation approach using point system method: (1) an adjusted factors and weight; (2) standardized factors and weight using Cullen Egan Dell. Finding in this study shows that different approach in conducting the job evaluation results different number of job clusters. It will affect the proposed compensation design, which from the first approach (1) requires an increase in compensation budget of 4.9% from the existing budget, while second approach (2) requires a higher budget allocation of 11.6%. Based on the results of the comparison, company can choose alternatives that align with availability of budget, business strategies and compensation strategies to retain employees or recruit potential prospective employees.","PeriodicalId":156644,"journal":{"name":"Proceedings of the 2019 1st International Conference on Engineering and Management in Industrial System (ICOEMIS 2019)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115827317","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}

During the railway production, there is problem in the assembly process of car body sub assembly, namely underframe. Defective products have been found which cause the underframe to be repair, so the underframe production is delayed. The type of defect is porosity, which results from the welding process during the assembly process. Therefore, this study uses the Six Sigma method with the Define – Measure – Analyze – Improve (DMAI) approach to give improvements on welding process so the defect which is porosity will be reduced or may not exist and to maintain the quality. Define phase using Supplier – Input – Process – Output – Customer (SIPOC) diagram and Critical to Quality (CTQ). Measure phase using c-Chart to know the process stability, then Cp and Sigma Level to know the process capability. Fishbone diagram and Failure Mode Effect Analysis (FMEA) are used in the analyze phase. The result of FMEA is the base to design improvements in the improve phase, the improvements are material storage characteristics, workstation design and procedure display. Introduction As one of railway manufacturing company in Southeast Asia, quality is an important factor in maintaining customer satisfaction and one of the key success in business competition [1]. Also, this railway manufacturing company has to improve its quality, which is the products that have been produced must be zero defects [2]. The core product of this railway manufacturing company is train. One train consist of two main components, which are bogie and car body. The components that arrange one car body are shown in the Figure 1. One of car body sub assembly, namely underframe (Figure 2), has its problem. The problem is, defective products have been found which cause the underframe to be repair, so the underframe production is delayed. The production data of underframe is shown in Table 1. It can be seen from Table 1 that the type of defect is porosity. The identified defects are located in different connections, which are on the side sill connection and the center sill connection. There are 12 joints that need to be inspected on each connection, so the total is 24 joints. Porosity (Figure 3) comes from the welding process during the assembly of underframe’ components. The components of underframe (Figure 2) are front end, rear end, side sill, center sill, and cross beam. Therefore, this study uses the Six Sigma method with DMAI approach to give improvements on welding process so the defect which is porosity will be reduced or may not exist and to maintain the quality. 1st International Conference on Engineering and Management in Industrial System (ICOEMIS 2019) Copyright © 2019, the Authors.

Production unit of lithium ion battery Sebelas Maret University (UNS) that become Indonesia’s first solution to the problem energy in Indonesia, where the need is increased while the source of its acquisition will be increasingly rare. In this case, it is important to supply chain performance rated. Supply Chain Operations Reference (SCOR) is method of supply chain performance assessment based on 5 indicators; reliability, responsiveness, cost, asset management , and agility. Assessment of the SCOR framework presents business processes, performance indicators, best practices and technology to support communications and collaboration among supply chain partners to improve the effectiveness of supply chain management and consummation of the supply chain. SCOR focus on causality measures in the form of a linear correlation. This situation becomes a weakness because the SCOR method cannot continue the steps specific to a future that can predict performance. Study on SCOR combined with system dynamics (SD) can identify 4 perspective and variable interactions associated with causal loop design model. SCOR model and SD gives the value of a more effective and compelling. The initial findings of this study are 27 verified metrics which were then made causal loop diagrams that illustrate the causal relationship between these metrics. The final result of this research in the form of a simulation model at powersim or called flow diagram can show the entire supply chain system and its relevance.","PeriodicalId":156644,"journal":{"name":"Proceedings of the 2019 1st International Conference on Engineering and Management in Industrial System (ICOEMIS 2019)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125329561","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 optimum core design and magnetic resin characteristic were investigated to improve the thermal shock reliability of the component upon reflow soldering. Finite element modelling (FEM) was utilised to simulate the response of the assemblies to the variations of the core inner radius (rc), upper flange thickness (t) and the coefficient of thermal expansion of magnetic resin (CTEmr). The assessment of those designs was conducted at a reflow oven, modelled by the computational fluid dynamic technique (CFD), on sixteen designs generated by the orthogonal array. The results showed that the inner radius of the drum core was the most vital parameter in designing a drum core in preventing core crack upon reflow soldering. The optimum design of the drum core was obtained at 0.5 mm inner radius of drum core, 0.3 mm upper flange thickness and 2.8 ppm/K coefficient thermal expansion of magnetic resin. Those findings may be used as a reference for designing a similar drum core of a power inductor.","PeriodicalId":156644,"journal":{"name":"Proceedings of the 2019 1st International Conference on Engineering and Management in Industrial System (ICOEMIS 2019)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127065513","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}
