In this case, salt farmers, as a significant part of the salt trade, need careful trade channels to get optimal profits. Determination of supply chain channels on a salt commodity is not lonely affected by the price but driven by many external factors. Identify the most significant contributor to the decision making of it, and the Delphi-based approach becomes a promising way. This study designed using qualitative with two rounds of Delphi method, namely to determine the factors that influence the salt supply chain system and the second stage to establish consensus based on the factors obtained in the previous stage. Using a purposive sampling method, the subjects of the study were seven respondents from salt supply chain players in Indonesia. The questionnaire was arranged based on factors affecting the salt supply chain system. As a result, the consensus with the experts was achieved after the 3rd interview, related to factors: number of family members, income rate, salt quality, salt production, price, payment system, price information, capital, and transaction cost. Factors that influence the choice of supply chain systems will have an impact on the amount of income of farmers.","PeriodicalId":431443,"journal":{"name":"Proceedings of the 2020 2nd International Conference on Management Science and Industrial Engineering","volume":"120 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116211042","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}

An ergonomic analysis of sit-to-stand (STS) is needed for people to improve the daily activity, avoid the re-injury and be a reference by documenting the influences on human musculoskeletal system. The goal is to investigate the effects of arm postures and leg positions on joint motion and joint loads during sit to stand period. The twelve young college students without any musculoskeletal disorder were recruited. Three contexts of the sit-to-stand experiment were a normal sit posture with 90 degree of knee joint (N), a normal sit with feet backward 10 cm from sitting with 90 degree of knee joint (FB) and a normal sit posture with arms forward (AF). The height of the chair was adjusted with their leg length from ground to knee joint. The six-camera motion analysis capture system with two force plates were used to collect the segmental movement and ground reaction force. The movement time, kinematics and kinetics of joint were then analyzed. The results were found the range of motion of the hip, knee and ankle were significantly affected by chair raising strategies (p<0.05). FB groups had lower peak moments of the hip than N and AF groups. The largest peak knee moment occurred in FB groups. The peak knee moments among three groups are significantly different (p<0.05). The results of this research would be a reference for strategy use for older people or people who are difficult to rise from sit.","PeriodicalId":431443,"journal":{"name":"Proceedings of the 2020 2nd International Conference on Management Science and Industrial Engineering","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133943044","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 study assesses which among the Agile practices should Company C improve on to meet its project timeliness. Company C was evaluated against other IT companies, namely Company A, B and D based on how in-depth the Agile practices were applied in the company using one-way ANOVA to test the difference of means of the companies on each Agile practice. The Agile practices that Company C excels and needs improvement were obtained. A binary logistic bootstrap regression is performed to determine which Agile practices positively affect in improving the project timeliness of Company C. Based on the identified best implementation of the Agile Scrum practice in Company C from one-way ANOVA, and the positive and negative coefficients in regression, the practices that should be maintained and improved were obtained for the formulation of the Agile framework of Company C. To improve project completion rate, Company C should improve on the following practices: increasing frequency of evaluating backlog items at least every other sprint, limiting stand-up meeting to 15 minutes, creating separate implementation task, conducting sprint planning with key persons, consistent iteration length, more frequent iteration demos, performance of unit testing, understanding architectural design and implemented by the team, performing pair-programming on key portions, collaborating more frequently of team members and using of formal written document as supplement for informal communication should be implemented.","PeriodicalId":431443,"journal":{"name":"Proceedings of the 2020 2nd International Conference on Management Science and Industrial Engineering","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115199189","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}

Thus, the courier service industry is classified under Warehousing and Support Activities for Transportation (WSAT) and Postal and Courier Activities (PCA) of the Philippine Standard Industrial Classification (PSIC). The musculoskeletal disorder (MSD) under WSAT and PCA on 2013 totals to 1075 or 56.76% of occupational diseases. The researchers aimed to conduct ergonomic assessment in the outlets and hubs of one of the largest courier companies in the Philippines. The researchers gathered information about the demographics, work methods, workplace design and working conditions of the workers through survey questionnaires, interviews and observations. The prevalence of the MSD of workers in hubs is more serious compared to those in outlets. The most affected body part of workers is lower back. Factors affecting outlet customer service representatives are the setup, table height, frequency of exercise, proper lifting, years working, weekly working days, sitting hours, postures, workplace design and transaction rates. For the workers in hubs, the significant factors that affect them are the frequency of exercise, standing time, workplace design, weekly overtime, age, transaction rates, and whether they know about proper lifting. This paper proposes an ergonomically designed workplace and recommends strategies to reduce the worker's MSD in courier service industry.","PeriodicalId":431443,"journal":{"name":"Proceedings of the 2020 2nd International Conference on Management Science and Industrial Engineering","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123368552","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}
