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.

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.

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

Pekerjaan manual masih banyak ditemui  pada berbagai aktivitas kerja. Pekerjaan manual yang dikerjakan secara berulang (repetitive) dengan gerakan kerja monoton dan waktu kerja yang lama berpotensi menimbulkan kelelahan kerja. Pada gerak monoton repetitive terjadi pembebanan otot yang terus menerus. Postur kerja yang salah membuat kelelahan menjadi lebih cepat terjadi.  Postur kerja yang  tidak baik ini seringkali diakibatkan oleh desain fasilitas kerja yang kurang memperhatikan kesesuaian dengan penggunanya. Pada pekerja laundry aktivitas menyetrika pakaian merupakan kerja repetitive monoton yang kurang didukung fasilitas yang sesuai. Postur kerja dengan berdiri dan terjadi twist serta seringkali membungkuk. Operator setrika harus melakukan kegiatan setrika selama lebih dari 8 jam. Penelitian bertujuan melakukan redesain pada stasiun kerja setrika agar diperoleh postur kerja yang baik. Perancangan stasiun kerja  menggunakan software Jack 8.2. Stasiun kerja yang terdiri dari meja dan kursi dirancang dengan memperhatikan antropometri dan kebutuhan gerak operator. Evaluasi desain dilakukan dengan mengevaluasi postur kerja dengan menggunakan analisis biomekanik, menggunakan analisis toolkit yang meliputi analisisi SSP, LBA, RULA, dan OWAS. Dari hasil evaluasi, dihasilkan postur usulan yang diberikan adalah, pekerja duduk pada kursi dengan posisi tubuh tegap, arah kepala sejajar dengan arah objek yang dikenai pekerjaan, dan pekerja dihindarkan dari posisi kerja membungkuk dan twist. Abstract(The Design of Working Station and Working Posture Using Biomechanic Analysis to Reduce Static Load and Musculoskeletal Disorder).The work that is done manually is usually done repeatedly with monotonous movements and long working hours. If the muscle’s working too hard, the muscle will be found damage and fatigue. The right working posture can improve the worker’s ability to finish the job. Wrong posture is often caused by the facility design that unsuitable to operator.

Abstract The ergonomics and environment factors have been the main issue for the mining industry for many years,and their profiles are increasing. To ensure an ergonomics work environment, it is possible to requirea particular attention especially in this industry sector. Due to lack of ergonomics knowledge and lowawareness among engineers in the mining industry, this may lead to become the central issue in Malaysia.The aim of this study is to investigate the physical risk factor associated with work-related musculoskeletaldisorder (WMSDs) by using workplace ergonomics assessment (WERA) among workers in the miningindustry. Based on the investigation, the action level of the WERA is medium that stated that the tasksneed to be investigated further and it requires changes. All physical risk factors involved the five top bodyregions such as shoulder, wrist, back, neck and leg. These have been identified to have an associationWMSDs by previous researchers. There were eighteen subjects selected in this investigation study. Thosesubjects were chosen according to their job tasks. The results of the analysis were used to improve theprocess of work, design of the workstation and also improving the work posture to enhance the comfortlevel of operators. This study is crucial for the mining industry because there is a lack of information andresearch about the ergonomics issues in the industry. The overall finding indicated that the whole processof selected job tasks will contribute to musculoskeletal disorder either for a short or long time exposure.

History records that Singkawang was an inseparable part of the conflict between ethnic groups in West Kalimantan. This article aims to examine three things, namely (1) the description of Coser's structuralist theory, (2) the strategic role of the city of Singkawang, and (3) the relevance of Singkawang City to Coser's theory. This research was studied with a qualitative descriptive. The research subject is the object of research is the city of Singkawang. Data collection techniques are carried out by literature study, interviews, and observations. The results showed that (1) the presence of conflict can play a role in restoring the social integration of members of society. Besides, the presence of conflict also plays a role in strengthening the social and emotional bonds of its followers. (2) Singkawang had a strategic role as a trading area and transit point for gold miners during the Sambas Sultanate. This condition lasted for a long time and made the people of Singkawang at that time learn to blend in with each other. In its development, the history of assimilation made the city of Singkawang finally used as one of the locations when there was an inter-ethnic conflict in West Kalimantan. (3) Coser's theory teaches that to avoid conflict there needs to be a safety value. In Singkawang City, safety value is carried out through natural assimilation through marriage, including culture. Apart from that, there is also artificial assimilation carried out by creating associations of both ethnicity and religion.
