Abstract

Background. Tofu is the familiar Indonesian food. It is crucial to produce Tofu effectively and efficiently. Aim. This research aims to help Mr Andi's tofu factory in Palembang, which has problems with the round tofu wrapping process. Workers are often absent due to specific events, which causes the owner to experience difficulties in producing round tofu. The processing time will be slower than usual, and the owner will have to hire spare tofu wrappers with more expensive wages. This round tofu maker is designed for Mr Andi's tofu factory. Methods. The research method applies ergonomics in product design (Ergo-Product Design), which applies the AT, SHIP approach, and anthropometry. Result. The research result is a tool made based on the dimensions of round tofu, size 6.25x6.25x4 cm3. The cover, base, and pressing cloth size is 50x50x3 cm3. The core part consists of a wooden part measuring 50x50x10 cm3 and a small square inner part of aluminum measuring 6.25x6.25 cm2. The fabric presses are the same size but added with small nails made of ¾-inch mild steel positioned right in the center of each small square in the core. Conclusion. The tool manufacturing cost is 560,000 IDR, and the maintenance cost is 10,000 IDR per month. Break event point in 13,728 units or 8,227,778 IDR and payback period in 2 days. Regarding environmental aspects, liquid waste from the tofu filter still exists because it does not change the production process. Worker energy becomes lighter, down 32 kcal/hour. Implication. The tofu packaging process time is faster, and the amount of production is more significant.

Abstract

Belimo Food Industry factory is engaged in the production of crackers and kemplang with the Belimo brand. Observations made at the packing workstation, there is still a buildup or bottleneck in the press machine that is not optimal and performance is not efficient because it violates many ergonomic principles in the manufacturing industry (Ergo-Manufacturing). This research explores the integration of Ergo-Manufacturing concepts with simulation. The research aims to improve performance and reduce process lead time. The research method used is quantitative-descriptive with primary data. Data processing uses the integration method of the Ergo-Manufacturing concept with Arena software-based simulation so as to provide solutions that can optimise the performance of process waiting time, improve efficiency, work comfort, and production capacity at the packing workstation. The results of the study after applying Ergo-Manufacturing with work environment settings can minimise the waiting time of the initial condition process with a process time of 58.273 minutes. Under the conditions of improvement scenario 1, the process waiting time of 26,830 minutes can reduce the process time by 60%, under the conditions of improvement scenario 2, the process waiting time of 14,562 minutes can reduce the process waiting time by 80% and under the conditions of improvement scenario 3, the process waiting time of 12,483 minutes can reduce the process time by 85%. The results of the BEP decision analysis for scenario 1 were selected by adding 1 press machine to 2 press machines which can increase production capacity by 128 products and reduce overtime costs incurred by the company for 1.5 hours by IDR 40,500 and BEP investment in press machines takes 3 years.

Abstract

Background, The prospect of oil palm plantations is currently rising significantly to become a favourite business. However, the work activities of TBS loading-unloading workers are still performed without paying attention to ergonomic aspects and have the potential for MSDs. Aim: To map the potential MSDs of TBS loading-unloading workers, serving as a basis for improving the work system. Methods: The inclusion sample of TBS loading-unloading workers was observed and interviewed using the NBM questionnaire to diagnose potential MSDs resulting from MMH work activities. Ergo-MMH was applied to provide recommendations for improving work system design based on the AT and SHIP approaches. Results: The primary causes of MSDs are unnatural working attitudes and excessive muscle tension resulting from work systems that are not designed per the limitations of workers. Twelve body parts are directly involved in MMH activities. Conclusions, Possible MSDs on the back, left and right shoulders, right and left upper arms, right forearm, left and right wrists, left and right hands, and upper and lower neck. Implication, Ergo-MMH-based mapping of potential MSDs in manual material handling activities of TBS loading-unloading workers for the academic world; research, theory development, and education. For society, public awareness, community development, and social support. For the nation and state, work safety, economic growth, and public health. For the international community, international collaboration, standards development, and technology development

Abstract

Background. PT SMS produces bottled drinking water (amdk) in gallons and cups with Vit and Forme brands for gallon packaging and Airnes, Forma, and OK Oce brands in cup packaging. In identifying the problem at PT SMS, it was found that the work system is not well-designed and lacks ergonomics at several workstations, which has an impact on achieving less than optimal daily productivity. The output per work shift set by the company is 2,100 gallons and 3,150 boxes for cup packaging, but in fact, it can only produce approximately 2,050 gallons and 3,000 boxes. Aim. Analyze the factors that cause the work system to be less effective and less ergonomic. The formulation of work system factors encompasses physical work environment factors, equipment, infrastructure, machinery, workload factors, and organisational factors. Methods. The Macro Ergonomic Analysis and Design (MEAD) method is used to identify factors that affect the work system and then implement improvements and design changes based on the identified factors. Results. Physical work environment factors and organisational factors are problems within the work system at PT SMS, as the workspace designated for the production workflow lacks ergonomic support for employees' postures while working, and task management is inadequate. The machinery has not been crafted based on the anthropometric measurements of the workers. Oversight is absent for the work being done, and the standard time required for the production process has yet to be established. So that it increases productivity per work shift at PT. SMS is not optimal and experiences over time. Conclusions. Redesign of physical work environment facilities, scheduling of rest periods, and organisational factors through supervision from PT SMS resulted in output per shift meeting the standards set by the company.. Implication. The application of MEAD can identify factors that cause suboptimal productivity. Redesigning ergonomic physical work environment facilities, scheduling rest periods, and supervisory organisational factors within the company have an impact on optimising productivity, as measured by the output per shift set by the company
