Work posture is a decisive point in analyzing the effectiveness of a job. If operators have a good and ergonomic work posture, they certainly have good job results. Operators who easily experience fatigue can be seen from the results of their completed work. Their work decreases and is not as expected, followed by various musculoskeletal complaints on parts of the skeletal muscles suffered by a person ranging from very slight to severe complaints. The complaints to injury are usually termed complaints of musculoskeletal disorders (MSDs) or complaints of musculoskeletal injuries. The OWAS method is a method that provides output in the form of a category of work attitudes that are at risk of work accidents in the musculoskeletal section. Based on the results of research using the OWAS method, it is known that out of the 7 operators observed, 3 operators are in category 2, namely dangerous or require improvement in work posture, while 4 operators are in safe","PeriodicalId":177991,"journal":{"name":"STRING (Satuan Tulisan Riset dan Inovasi Teknologi)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116654931","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 a manufacturing company engaged in bodywork sector. Every company surely expects high profit. One of the ways to achieve the goal is by minimizing the expenses. Economic Order Quantity (EOQ) and Just In Time (JIT) methods are commonly used methods to save inventory costs. This study aims to compare which method is more effective and efficient in reducing inventory costs at the company. The results of the study show that the JIT method can reduce inventory costs by 91.14% for plate with 2mm 4x8 standard and 93.62% for plate with 3mm 4x8 standard, while the EOQ method can reduce inventory costs by 33.45% for both types of the raw materials. Based on the results above, it can be concluded that JIT method is more effective than EOQ method in reducing inventory costs in the company.","PeriodicalId":177991,"journal":{"name":"STRING (Satuan Tulisan Riset dan Inovasi Teknologi)","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131785464","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 characteristics of a sensor that only produces analog quantities are a challenge itself in implementing digital technology using sensors. The combination of sensors and Arduino microcontrollers can be used to control various equipment systems. One of the applications of temperature sensors and Arduino microcontrollers is to control the flow of heat in a clothes dryer. The hot air generated by the equipment will burn the air in a tube. The resulting heat is flowed into the clothes dryer using a fan. To make the temperature in the clothes drying chamber stay at a certain point, a device is needed to regulate the flow of heat exhaled from the heating chamber. The regulation of the temperature is performed by adjusting the on and off buttons of two fans that blow hot air into the clothes drying chamber. By adjusting these two devices using a temperature sensor and Arduino microcontroller, the temperature in heating chamber can be maintained in a certain temperature point.

This study aims to determine the priority of reports that need to be prioritized by the helpdesk service in communicating through Zendesk media. The process of determining the priority of Zendesk's media report features uses the AHP method in the weighting which is then tested with the Consistency Index and Consistency Ratio to find the priority percentage. It is later followed by the determination of helpdesk officers’ activities in supporting the report criteria that need to be prioritized in accordance with the company's vision in providing services. The test results can be used as operational standards and references for helpdesk officers in carrying out their duties. From the AHP weighting and CI & CR testing which are then converted to percentages, it is found that the percentage of the First Response report criteria is 49%, followed by Solved Ticket of 31% and Agent Touch of 20%.

The results obtained from this study show that the vulnerability to landslides is relatively high, with a large area around 51.63%. This area is spread over hilly areas. For built land, its level of vulnerability to landslide in both the high and very high categories, namely in zones Z-4 and Z-5, is caused by slopes of 25 to > 40%, with rock types with a high degree of weathering and with built-up land cover. The use of remote sensing and geographic information system in assessing landslide in the research area can be used as a guide for the proper use of land to avoid disasters that may occur.","PeriodicalId":177991,"journal":{"name":"STRING (Satuan Tulisan Riset dan Inovasi Teknologi)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115556405","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}

Work fatigue is a condition in which a person experiences both physical and mental deterioration. When someone experiences work fatigue, his work productivity, efficiency and effectiveness can also decrease. Excessive working time from existing rules can result in work fatigue. PT. United Steel Center has a division with a very long working time duration of 33,420 minutes or 557 hours in February 2022. Based on this, it is necessary to conduct an analysis to find out whether there is subjective fatigue in machine operators in the division.

Based on the results of distributing the SSRT questionnaire and analysis, it is known that from eight operators, there are seven operators who experience low work fatigue, while one operator experiences high work fatigue.","PeriodicalId":177991,"journal":{"name":"STRING (Satuan Tulisan Riset dan Inovasi Teknologi)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125514323","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}
