Abstract

Indonesia, particularly East Indonesia, accounts for up to 85% of the world's wet seaweeds. Bulukumba is one of Indonesia's most important seaweed producing places. In Babana Hamlet, Bulukumba Regency, 80% of the people is employed as a seaweed grower. Coordination and cooperation between all supply chain actors for seaweed commodities in Bulukumba Regency is required to meet the needs of the market. Poor quality seaweed results in losses to farmers. If this happens, it will result in disruption of the supply chain network, and reduce the profits of the perpetrators. Macroergonomic Structure Analysis (MAS) consists of three main elements of a sociotechnical system, namely the technological subsystem, the personnel subsystem, and the external environment. The only subsystems used were the personnel subsystem and the external environment subsystem. The risk with the highest weight obtained was on the personal subsystem in the professionalism factor with a weight of 0.32 (Motivation decreased during the rainy season). For the external environment factor is a weight of 0.33 (Rainy Season) which is associated with the rainy season. This is because the rainy season has the worst effects. Then the drying process will also be interrupted. The production of seaweed breeders greatly influences the supply chain process. If the risk to seaweed farmers occurs, then the collector traders in carrying out the supply will take longer and the capacity to be transported will also be reduced. The answers found for improvement include picking seeds, acquiring a nursery, acquiring a laboratory, and establishing a landbase to prepare for adverse weather.

Abstract

PT. AFS is a Limited Liability Company engaged in catering services. One of the most important divisions in this field is in the warehousing department. Receiving is the place where the goods are entered, while the store is the place where the goods are stored for a period of time with reference to the expiration date of the product. Goods collection is done when receiving incoming goods, moving goods from the receptionist to the store, and when requesting goods from the production room. Body posture is a determining factor in analyzing the effectiveness of a warehouse operator's work. If the operator's work attitude is wrong or not ergonomic, the employee will tire easily and bone abnormalities can occur. Complaints of Musculoskeletal Disorders are complaints of skeletal muscles that are felt by a person from very mild to severe complaints. For the RULA and OWAS methods, posture analysis is only carried out in the main warehouse. The final Rapid Upper Body Limb Assessment (RULA) score for both workers was Score 7 (Action Level 4) which indicates that this condition is dangerous and requires immediate inspection and changes (on the spot). And the Ovako Work Posture Analysis System (OWAS) shows category 4 (This attitude is very dangerous for the musculoskeletal system. Needs to be corrected immediately/currently) and Category 1 (in this system problems in the musculoskeletal system don't need to be fixed).PT.

Abstract

The progress of the shoe industry in Indonesia has encouraged small and large shoe entrepreneurs to compete in terms of quality, because consumers are very dependent on quality, so good quality control is needed in order to make consumers loyal customers. UD. XYZ is a small company that has problems with quality control so it really needs quality control using the SQC method. And the result was that UD. XYZ that the P control chart data shows that none of the 30 points are outside the control limits, so it can be concluded that the process is under control, but UD. XYZ still has to improve product quality by evaluating 4 elements (machines, people, tools, and methods).

An aid used to move raw materials is a hand stacker that can only be operated by one person. The use of this aid makes the operator who must be assisted by other operators to pull the hand stacker. Based on the Nordic Body Maps questionnaire, the highest pain complaints were in the lower neck, left shoulder and right shoulder. This condition is dangerous for the operator as shown by the results of RULA (score 7) with a level of category 4 (this condition is dangerous and necessary to make changes immediately).
