Sinar Jaya Maros has a very high variation because there is no standard raw material composition that meets SNI standards, according to SNI 03-0349-1989 that the requirements for hollow concrete bricks for K-350 concrete quality must have a compressive strength of 350 kg/cm2. This research was conducted to design an improvement or quality improvement of hollow concrete brick products in CV. Sinar Jaya Maros. The quality improvement is in increasing the compressive strength of the concrete brick with an optimal composition. Quality improvement was carried out by using the Taguchi method experimental design to obtain the optimal combination of compositions. The orthogonal array notation used is L9(34) with material control factors in the form of cement (A), water (B), and (C), and Casting plaster (D). Data processing is carried out by calculating ANOVA on the average value and S/N Ratio with the best nominal classification. The classification was chosen because the closer to the compressive strength based on the SNI of hollow concrete bricks, the higher the quality of the concrete bricks. This ANOVA calculation is carried out to know which factors have a significant effect on the compressive strength of concrete bricks. The test conducted to determine the quality of lightweight bricks is the compressive strength test of concrete which is carried out using a compression machine. Based on the results of data processing, the ratio of the optimal composition of cement:water: sand was obtained by 2:1:3,5. Confirmation experiments prove that the compressive strength of the composition is robust.","PeriodicalId":367802,"journal":{"name":"Journal of Industrial System Engineering and Management","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128485474","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}

Sumber Setia Budi is a company engaged in the nickel mining industry as a contractor partner for the central company PT. Antam Tbk UBPN Sultra is located in Kolaka district, Pomalaa sub-district. The purpose of this study was to determine the effect of work shifts on subjective fatigue in the Mechanic Workshop section using a Cross-Sectional approach with multiple linear regression analysis, the sample amounted to 21 respondents. The instrument used is a Subjective Self Rating Test (SSRT) questionnaire and the types of data are primary and secondary data. The results of the analysis using multiple linear regression with the f test simultaneously show that the significant value and calculated F value between groups of the morning (X1), afternoon (X2), and night (X3) shift simultaneously on subjective fatigue (Y) is F count 2,571 > F table 3.13 and a significant value of 0.229 > 0.05, so it can be concluded that there is an effect between the morning shift (X1), afternoon shift (X2) and night shift (X3) on subjective fatigue but the effect is not significant. To reduce and overcome fatigue experienced by workers, the company should further improve the comfort and facilities of the work environment to create a more comfortable and ergonomic work environment","PeriodicalId":367802,"journal":{"name":"Journal of Industrial System Engineering and Management","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115478315","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}

Bumi Trans Energi is one of the companies engaged in 3 Kg LPG cylinder retested repair, this company repairs 3 Kg LPG cylinders that have been damaged for 5 years, damage to the handguard, and footring, and welded joints on the tube. In the repair process, there are 5 stations and 21 work processes, PT. Bumi Trans Energi encountered a problem in the repair line at station 1, and a bottleneck occurred. This bottleneck occurs because the production flow is not smooth from one station to the next, this problem causes each work station in the repair path to have a different speed level, which causes material accumulation between work stations, and waiting times between work stations. For this reason, this study aims to determine the number of workstations needed to get maximum efficiency and balance the repair process line when bottlenecks occur. Observations were made in data collection 30 times, each work element was observed and calculated in the data uniformity test and data adequacy test to obtain standard time. The results of this study were the application of 3 work stations from 5 initial work stations, there was a reduction in idle time to 425,74 seconds ( 7 minutes) following the increase in track efficiency to 84,17 % the balance delay decreased to 15,83 %, and the Smoothness Index was 212,63. The actual idle time was 1004,97 seconds (17 minutes) while the proposed trajectory idle time used the Ranked Positional Weight method of 425,74 seconds (7 minutes). The difference between actual and proposed idle time is 10 minutes, and the placement of work elements at work station 1 (one) consists of 9 work operations, while work stations 2 (two) consist of 1 work process, and work stations 3 ( three ) consist of 8 work processes","PeriodicalId":367802,"journal":{"name":"Journal of Industrial System Engineering and Management","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125879028","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 company's main business units are the manufacture of animal feed, chicken breeding, poultry processing, and agricultural cultivation. This company will automatically continue to increase its production results both in terms of quantity and in terms of quality to be able to compete in the market so that it can expand market share and offer products at affordable costs for consumers. At present, business progress is strongly influenced by fluctuations and variations in consumer demand. This also has an impact on the production of chicken feed carried out by PT Japfa Comfeed Indonesia Tbk Makassar unit. With the increasing demand for chicken feed, an effort is needed so that the production process runs according to available and profitable resources. This research aims to determine the optimal amount of production to generate optimal company profits. The method used in this study is the goal programming method because it can solve problems optimally with more than one goal. The results of this research show that the product of goal programming optimization is more profitable than the companies. The results obtained from this research are the optimal number of products is 4,967,155 kg, and the minimum production cost is Rp. 1,382,685,942,075, and the sales profit is Rp. 314,569,267,925 for a period of one year.","PeriodicalId":367802,"journal":{"name":"Journal of Industrial System Engineering and Management","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127402040","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}
