Based on our observations, the operator works 8-hour regular shifts or 12-hour long shifts for 5 – 6 days a week. During these shifts, the operators work in front of the CNC machine while standing upright without any tools to rest. Preliminary research was conducted to evaluate these conditions the results show 13 out of 20 CNC machine operators complained about physical fatigue while working the CNC machines. It can also be concluded that the operators are experiencing excessive workload based on a workload assessment using the Quick Exposure Check (QEC) method. To solve this problem, a standing chair is designed with ergonomics in mind. The dimensions of the standing chair are based on the anthropometry of the CNC machine operators, which was never used before. The design process is conducted using the Theory of Inventive Problem Solving (TRIZ) methodology. Need statements from the CNC machine operators and design requirements from the stakeholders are converted into design specifications using TRIZ methodology. Parameters are determined to increase the capability of the existing design based on the design specifications. The result of this research is a standing chair that is suitable for the operator’s needs. Based on the analysis of the design result and the stress analysis simulation, it can be concluded a functional standing chair can be ergonomically designed with the TRIZ methodology.","PeriodicalId":217640,"journal":{"name":"International Journal of Innovation in Enterprise System","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122239591","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}

Twitter is a social media platform that allows users to share information and opinions directly with fellow users. Tweets given can be in any form, either positively or negatively, so one of the methods used is sentiment analysis. Sentiment analysis helps determine an opinion or comment on an issue, whether the response is positive or negative. The Naïve Bayes algorithm is used in sentiment analysis because it is suitable for tweets or text data that is not too long or short text. The initial stage of sentiment analysis is text pre-processing which consists of Cleaning, case folding, tokenizing, and stopword removal. Then the data is labeled manually. The analysis results are visualized as bar charts, pie charts, and word clouds. Then the word weighting is carried out using the term frequency-inverse document (TF-IDF), and classification is carried out using the Naïve Bayes classifier. From the test results, the accuracy value of the confusion matrix is 82% from 2600 tweet data with 80% training data composition and 20% test data.","PeriodicalId":217640,"journal":{"name":"International Journal of Innovation in Enterprise System","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116953636","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}

Briquette production is carried out using a hammer mill where the raw material for briquettes is charcoal which is then crushed into charcoal granules. The packaging process is still done manually using a shovel to fill the 50kg sack and then take it to the sewing machine. The worker's posture when using a shovel has a Rapid Entire Body Assessment (REBA) score of 12 so it has a high work risk of musculoskeletal disorders (MSDs) and requires immediate improvement. The working environment at the company produces pollutants, meaning that there is no capture container for the fall of charcoal grains from the hammer mill. Based on the existing problems, a redesign of the existing machine is needed. The proposed machine was designed using the Reverse Engineering method because the existing condition already uses the machine then the existing machine is decomposed to find out the components and functions of the existing machine to find alternative concepts. The ergonomic approach uses REBA and LBA to determine changes in worker posture and the forces acting in the human spine. The DEM approach was chosen to find out if the charcoal grains dropped from the hammer mill were successfully captured and to find out the flow of the charcoal grains. The results of the proposed machine design have a good impact on workers in the packaging process.","PeriodicalId":217640,"journal":{"name":"International Journal of Innovation in Enterprise System","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122233481","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}

In the last few years, Kliktrip has experienced several symptoms, including a decrease in revenue in the second year and the low level of brand differentiation of the Kliktrip online travel agent application based on customer perception compared to other online travel agent application brands. Based on the symptoms of these problems, it can be concluded that the brand of the Kliktrip online travel agent application is weak in customer perceptions of the online travel agent application because customers tend not to know the advantages offered by the Kliktrip online travel agent application brand. To be successful in facing competition with other business competitors, it is necessary to carry out sustainable development by building competitive differentiation by designing and improving positioning strategies. Based on the results of the perceptual mapping, there were 4 groups of competitive areas, the online travel agent Kliktrip application brand was in the same area as the Explorer.id online travel agent application brand which made it the main competitor of the Kliktrip online travel agent application brand.

There are differences in the characteristics of learning demands in engineering and non-engineering majors. Therefore, this study aims to evaluate the level of readiness and mental workload of students during the implementing full online learning based on the characteristics of the education department. Data collected by distributing online questionnaires to 180 students (90 students majoring in engineering and 90 students in non-engineering). Self-directed learning (SDL), technical readiness (TC), and comfort with non-face to face communication (CFT) used to measure e-learning readiness, meanwhile NASA TLX used to measure mental workload. Results showed differences between engineering and non-engineering students, especially in the Self-Directed Learning (p < 0,05). Non-engineering students perceived that they are more prepared to manage their learning process independently during online learning. Related to mental workload students perceive higher demands from online learning activities, the engineering group had higher level of time-related demands. According to correlation testing there was a negative and significant correlation between the self-directed learning dimension scores of E-Learning Readiness and the NASA TLX scores (p < 0,05). These results indicated the role of student’s e-learning readiness, especially self-directed learning readiness can reduce perceptions related to the mental workload experienced by engineering students in online learning. This condition was not applied on non-engineering students. Future study needed to explore the characteristics of study programs that relate to both variables and if the condition applied on other learning conditions such as hybrid learning.","PeriodicalId":217640,"journal":{"name":"International Journal of Innovation in Enterprise System","volume":"2015 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121443067","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 has three identical parallel spot welding machines that use a random method of production scheduling, based on machine capacity without any sequence of jobs, and only use daily production targets given to operators. Based on the data, the actual scheduling of the machines has a very large completion time difference between each machine, or the machine loading is uneven. As a result, the makespan becomes longer with a value of 440000 seconds (26 days). This research aims to minimize the existing makespan by giving proposed scheduling, using the suggested algorithm method, which has a small number of iterations and has an optimal result. The method begins with the longest processing time sequence rule which is used as the upper bound for the first iteration, then continued to calculate the lower bound and machine workload. The calculation stops at the 15th iteration because the completion time value exceeds the lower and upper bound so that the optimal scheduling taken is scheduled in the 14th iteration with a makespan value of 914412 seconds (16 days).
