Research on temperature is within the scope of control and monitoring. The process of controlling and monitoring temperature is influenced by the selection of the right temperature sensor. The temperature sensors that are often used are the LM35 sensor and the DHT11 sensor. The LM35 sensor has advantages in terms of a simple design and easy to implement, while the DHT11 sensor has the advantage because in one sensor package there are two functions, namely to measure air temperature and humidity. In this study, temperature measurement accuracy was carried out to facilitate researchers in determining the right temperature sensor. The data monitoring method uses the internet of things (IoT). The results of the research show that the DHT11 temperature sensor is more accurate and more stable than the LM35 temperature sensor. The results of the sensor test at room temperature, the DHT11 sensor has an accuracy rate of 97.21% while the LM35 sensor has an accuracy rate of 96.86%. While the results of the sensor test in the server room, the DHT11 sensor has an accuracy rate of 95.26%, while the LM35 sensor has an accuracy rate of 90.32%.","PeriodicalId":177991,"journal":{"name":"STRING (Satuan Tulisan Riset dan Inovasi Teknologi)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132203375","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}

One of which is discussed in DIE I is Biomechanics. Biomechanics is one branch of ergonomics that discussed about body mechanics for doing a job. In practicum of DIE I included in biomechanics is the Recommended Weight Limit (RWL), Lifting Index (LI), Rapid Upper Limb Assessment (RULA), and Rapid Entire Body Assessment (REBA). During this time, the calculation method of RWL, LI, RULA, and REBA on practicum DIE I still manually which causes the calculation becomes longer further practicum be delayed. This research aims to make the Software of calculation biomechanics by using Microsoft Visual Basic 6.0. Software that is made just for calculating RWL, LI, RULA and REBA. Based on testing by respondents as many as 21 people found the average time of manual calculation and software calculation. In completing the calculation, manual calculation takes an average of 297.246 seconds, while calculation with Software takes an average of 32.584 seconds.

PT Prima Kemasindo always strives to maintain the quality of its products, especially the Degan SK 150 ml product. However, there are still products that do not meet the standards set by the company. This is because the company has not used a definite method to monitor the control limits for the level of product damage. Thus, this study aims to determine the limits of damage control and the level of damage that occurs, the factors that cause product damage and its consequences, as well as suggestions that can be given to improve product quality. The research method used is Statistical Quality Control (SQC) with p-chart, pareto diagrams, and fishbone diagrams. The result showed that the level of damage of Degan SK 150 ml product was beyond the control limit and there were five types of damage that often occurred during the January-March 2021 period caused by human factors, methods, and machines. Thus, there are seven proposed improvements given to the company in order to reduce the level of product damage.","PeriodicalId":177991,"journal":{"name":"STRING (Satuan Tulisan Riset dan Inovasi Teknologi)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130190861","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 problem of optimizing production is still an obstacle for most businesses engaged in the food sector. One of them, Pak Yayat's Tofu Factory, produces two types of tofu, that is white tofu and yellow tofu. This study aims to optimize the amount of tofu production through the allocation of appropriate resources to achieve maximum profits. The method used is the branch and bound method and cutting plane. The sampling technique was done by purposive sampling. The results of the research using the branch and bound method obtained a combination of production of 36 white tofu boards and 75 yellow tofu boards which gave a maximum profit of Rp.1,872,000.00. While the cutting plane method results in a combination of 37 white tofu boards and 75 yellow tofu boards with a profit of Rp.1,886,500.00. It can be concluded that the cutting plane method provides optimal results with maximum profit compared to branch and bound. In this study, lingo software is used to simplify the data processing process and compare the results of calculations between manual and software to avoid calculation errors.","PeriodicalId":177991,"journal":{"name":"STRING (Satuan Tulisan Riset dan Inovasi Teknologi)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128487653","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}

Currently, Syntax Journal of Informatics does not have a feature for categorizing scientific articles based on their focus and scope. The research is conducted to classify scientific articles into categories according to focus and scope contained on Syntax Journal of Informatics’ page automatically by utilizing the text mining process. Text mining is a process that aims to get important information from the text. The method used in the research is Knowledge Discovery in Database (KDD) with stages of data selection, preprocessing, transformation, modeling and evaluation. This study will compare the classifications based on the title of the article. The algorithm used is the Support Vector Machine (SVM) using four SVM kernels, including the linear kernel, polynomial kernel, sigmoid kernel and RBF kernel. Data are divided into four scenarios by using traintestsplit, namely 60:40, 70:30, 80:30 and 90:10. The results of the study after testing the model are measured by of Accuracy, Precision, Recall and F-measure. The best results are accuracy of 70%, precision of 75%, recall of 69% and fmeasure of 71% in the 90:10 comparison scenario and linear kernel.","PeriodicalId":177991,"journal":{"name":"STRING (Satuan Tulisan Riset dan Inovasi Teknologi)","volume":"429 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124233124","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}
