Abstract

An ergonomic checkpoint is a method for evaluating the current work environment and implementing a more suitable work environment. When workers do work activities, the work environment is a critical component. Ergonomics is described as studying human factors in the workplace, including anatomy, physiology, psychology, engineering, management, and design. Based on preliminary observations, several activities allow potential hazards to arise, such as farmers’ lack of understanding of Personal Protective Equipment (PPE) when spraying pesticides and farmers’ use of t-shirts as a mask. Farmers repeated movements with a bent body position when planting rice seeds, which can cause potential health problems such as musculoskeletal. Using descriptive observational research, this study tries to objectively establish the conditions of the work environment concerning the circumstances. The Ergonomic Checkpoints method was used for data collecting. The results of the work environment assessment using the Ergonomic Checkpoints method in agriculture in Demangan Village revealed that five aspects that required corrective action, consisting of materials storage, and handling, had two points of incompatibility, machine safety had one moment of incompatibility, premises/workspace had one moment of incompatibility, and welfare facility had one moment of mismatch. Farmers in Demangan village should use Ergonomic Checkpoints to pay attention to the work environment in keeping with agricultural standards.

Abstract

Rural development is one of the primary keys to achieving sustainable development goals. Important changes in rural development strategies become inevitable and can be accommodated through rural tourism. Nonetheless, the models of rural tourism development, which depict the stages in developing and maintaining rural tourism, are still minimal. This research is conducted to fill the research gap by designing a conceptual model of rural tourism development. One-on-one interviews with four rural tourism development experts are done separately. The voice recording during the interviews is transcribed immediately after the interviews and proceeds with data processing using the qualitative coding method, which consists of open, axial, and selective coding. The qualitative coding method shows two main stages in rural tourism development: pre-development and development. The pre-development set consists of motivation and forum group discussion, while the development stage consists of planning, organization arrangement, HR development, product development, and marketing.

Abstract

This research develops a design model of a human-robot collaboration assembly line by taking into account the number of robots, tools, and setup time. The objective function of the proposed mixed integer linear programming model is to minimize cycle time. The results of model testing utilizing various scenarios reveal that the number of available robots, tools, and setup time can all have an impact on the assignment of assembly tasks at workstations. In other words, the suggested model takes into account the practical constraints of human-robot collaboration assembly line design. Further research will be conducted to build efficient algorithms for identifying solutions that take into account the assembly line in companies with a significant number of assembly tasks.

Abstract

Plastic has played a dominant role in human life as its usage is increasing over time. Plastic waste can harm the environment because plastic is not biodegradable. A collaboration adopted from the quintuple helix model was initiated by the local government of Cilegon, Indonesia, industry, and community to tackle the plastic waste problem. Plastic waste from households and industry is collected and processed in the plastic waste processing industry using the pyrolysis method producing gasoline, diesel, and kerosene. Kerosene is used by the community as fuel for cooking, whereas diesel and gasoline are used as boat fuels by fishermen. The collaboration is expected to provide economic and environmental benefits for the people in the Cilegon area. We conducted a cost and benefit analysis to evaluate the feasibility of this project from an economic and ecological point of view. The results will be used as input for conducting similar projects in other cities.

Abstract

Covid-19 has resulted in an increase in the people's need for vehicle ownership in order to avoid public transportation. People’s purchasing power, on the other hand, has also weakened. Therefore, they prefer to purchase affordable cars, such as used cars. Moreover, the Luxury Goods Sales Tax (PPnBM) discounts were officially applied to the purchase of the new cars in March 2021. This study aims at estimating the price of used cars using several data mining algorithms, such as Random Forest, K-Nearest Neighbour (KNN), and Naïve Bayes. By employing the RapidMiner tool, this study was able to evaluate the attributes affecting car prices. From the experimental results, random forest producers have the highest accuracy of 95.46%.  Then, this study figured out that brand, engine capacity, kilometres, colours, years, number of passengers, and transmissions are the most influential attributes to determine the estimation of the used car prices.

Abstract

This study aims to design a valid instrument for measuring the satisfaction of internal and external users on service quality provided by an institute for research and community service (LPPM) at a university. The SERVQUAL model is applied and a case study was conducted at Universitas Muhammadiyah Surakarta. Twenty-eight research attributes and twenty attributes of community services have been developed to measure the LPPM service quality based on five dimensions criteria namely tangible, reliability, responsiveness, assurance, and empathy. The developed attributes were validated by experts, e.g., head of LPPM and his staff. Further, using bivariate Pearson correlation and Cronbach alpha those attributes were tested for validity and reliability using SPSS 23. The result showed that all attributes in the instrument were valid and reliable. Furthermore, based on the Actual SERVQUAL Score (ASC), all attributes have score more than 75%, which can be classified as better than “good” according to the UMS Quality Assurance Agency (LJM). It indicates that the customers are satisfied with the services. However, based on the service quality gap analysis (i.e., gap between the perceptions and expectations of users), all statements showed negative results, which means that the perception is lower than expectation. Hence, improvements are still required especially to those attributes with high gap

Abstract

Along with the increasingly tight competition, companies are required to always be consistent in improving the quality of its products. Improvement of product quality can be achieved through minimization or even reduction of product defects. This study aims to minimize defects by providing improvement suggestions based on critical failure modes The Six Sigma approach is adopted to reduce the occurrence of product defects. The FMEA-FSWARA-FWASPAS FMEA method is integrated in the six sigma approach, especially to determine the priority of failure modes and the recommended efforts to minimize failure modes that trigger product defects. FSWARA is used to determine severity, occurrence, and detection weights as failure mode assessment criteria. Meanwhile, determination of the critical failure mode is based on the results of the evaluation using FWASPAS. This research is based on a case study in which 5 types of defects were found, namely, skewness, underfilling, leaks, broken lids, and broken boxes. The main causes lie in the human factor and the machine factor. The results showed that there were 3 critical failure modes, namely, the wrong setting of the cutter timer by the operator, the frequent change in the heater temperature, and material getting damaged

Abstract

Product returns are one of the obstacles faced by two-wheeled motor vehicle industry companies in Indonesia, where the company's head office is based in Japan. The obstacle faced is the excess cost of shipping product claims compared to the planned cost budget. These products are replacement parts for CBU (completely built-up) units for two-wheeled motor vehicles exported to Japan. This case will be solved using reverse logistics, where the initial analysis is carried out by finding the value of the bullwhip effect on the company's orders and requests. The next stage is forecasting for the next period using the ARIMA method using Rstudio. The results showed the occurrence of a bullwhip effect, and then the best result was the ARIMA model (0,1,3) (2,1,0). The value of the bullwhip effect managed to decrease by applying the forecasting model. Then optimizing the shipping cost of claim products processed by LINGO results in a 5% reduction in shipping costs from the budget.
