Coffee Roasting

The roasting process of coffee beans in West Kalimantan, especially Pontianak city, is still done traditionally. The coffee roasting process is done manually by using a fire stove as a heater. Workers with standing posture stir the coffee beans continuously, and it can take 4 hours for 20 kilos of coffee beans. Standing work posture is required for stirring the coffee beans but can cause fatigue in workers due to long-standing times and high heating temperatures. This situation causes the roasting process to be less efficient and can cause the roasting process to be uneven. The purpose of this study was to identify musculoskeletal complaints of standing work posture in the manual coffee roasting process and provide an evaluation of corrective work posture when using the design results of an automatic digital roasting machine. The methods used in this study were the Nordic Body Map (NBM) and the Rapid Upper Limb Assessment (RULA) to assess the level of risk of posture for musculoskeletal complaints. The results of the identification of body points that experience fatigue were carried out by distributing NBM questionnaires and evaluating the worker's posture using RULA on CATIA V5R20. Based on the existing NBM, the risk score is 78, and the final RULA score is 6, which means that immediate corrective action is needed because the work posture is categorized as dangerous and does not meet ergonomic principles. Improvement of working posture is made by designing a roasting machine that is digital and automatic. So the workers do not need to mix the coffee beans manually. Based on roasting machine implementation results, there was a significant change in the NBM score and the final RULA score. The NBM results obtained a score of 55 which means that the risk is moderate with the risk of fatigue in the neck, right leg and, left leg. Meanwhile, evaluation of work posture based on RULA on CATIA obtained a final score of 3, which means that the work posture is not dangerous and does not require immediate improvement.

Effective Design

Eliminating awkward and stressful working postures through the ergonomics workplace design is important in preventing work-related musculoskeletal disorders. However, effective design tools are currently lacking. Different postural analysis tools have been proposed to help evaluate workplaces in the level of postural stresses experienced by the workers, but they are not capable of supporting the proactive ergonomics in design. In an effort to address the problem, this study presents a novel memory-based workplace evaluation (MBWE) model. When given an input scenario expressed in terms of the worker anthropometric characteristics, the task requirement, and the geometric descriptions of the to-be-evaluated workplace design, the model computes the range of feasible working postures for the scenario, determines their postural stress levels, and presents a report on the overall postural risk level of the input scenario. The MBWE model combines the memory-based posture planning (MBPP) model and the Ovako working posture analysis (OWAS) method.

The people of West Kalimantan, especially in Punggur, Sungai Kakap, Kuburaya execute the grinding process of coffee beans with two types of processing, namely dry processing and wet processing. In the process of wet processing, there are problems, one of them is when grinding raw coffee process before the drying process. The process of grinding raw coffee is carried out with non-ergonomic equipment that causing the workers to have musculoskeletal disorders complaints, the workers are bending over so that they cannot work for a long time, and low productivity because workers have to separate the beans from the coffee skin which takes a long time. This study aims to analyze the level of musculoskeletal disorder risk experienced by workers when using a raw coffee grinder using the Rapid Upper Limb Assessment (RULA) method. In addition, an anthropometric principle was carried out to determine the size of the tool so it can be used in an ergonomic position and can get a good working posture recommendation when using the machine. Based on RULA analysis using CATIA, show a score of 6 when lifting coffee from the grinder, grinding raw coffee, and taking the coffee grind. The result of RULA indicates that repairs and changes are needed quickly because the work posture produced by the coffee grinder is not ergonomic. Meanwhile, the results of RULA analysis using a coffee grinder after the design showed a score of 3 when lifting coffee from the grinder, a score of 4 when grinding raw coffee, a score of 3 when taking the results of the coffee grind. The score shows that the resulting posture is ergonomic and feasible to apply.

Work facilities following the user's needs are critical because they support the production process for increased productivity. Currently, the tofu production process at Mr Samingin's MSMEs uses manual equipment to feel pain in their body parts when doing work every day. Making tofu begins with washing the soybeans thoroughly, then soaking the soybeans in water for 2 to 3 hours. Sometimes, it needs 7 hours, depending on the type of soybeans. In this soaking process, the soybeans will expand and then cleaned again by washing them several times. The next step is to grind the soybeans into powder with a grinding machine then boiled them. Then, filter the soybean porridge with a cloth to separate the pulp to be processed and the rest of the cooking water. This stage is very tiring as it is done manually by filtering in a shake. In addition, in the process of pressing tofu, there is a lack of attention to workers' work posture, which will impact work-related pain, especially if it is done monotonously and repeatedly. This study used the Rapid Upper Limb Assessment (RULA) analysis method as a guide in designing tofu screening work facilities. It is expected that improvements to work facilities can increase worker productivity at tofu production MSME.

Working facilities may influence worker’s working posture. CV.Tani Organik Merapi (CV.TOM) is an organic vegetables company. The company provides ”dingklik” (footstool) for working. While working with “footstool”, workers must bend their legs with high bend degrees as well as their back. This poor working posture is caused by bad working facilities. It’s important to check the working posture to know whether the improvement of working facilities is needed or not. Ovako Working Analysis System (OWAS) was used to check the badness level of working posture in every CV.TOM’s working activities. It’s identified that packaging section has the worst working posture. Then it was decided to provide a new working facility to improve working posture in packaging section. CATIA V5 was used to design the new working facility. Three ergonomics tools were used to compare footstool” working posture with the new working facility. Those tools are Rapid Upper Limb Assessment (RULA), Manual Task Risk Assessment (ManTRA), and Rodgers Muscle Fatigue Analysis (RMFA). It was found that the new working facility can substitute “dingklik” with lower posture score and safer. Keywords: Ergonomics; Catia; Comfortability; Facility; Working posture
