Abstract

The research that was carried out was to calculate the efficiency of the production cost of tofu using the Heuristic Silver Meal method. For every tofu production, raw materials are needed. The raw materials needed to make tofu include imported soybeans and vinegar. The problem that often occurs in the Home Industry XYZ is that there is an excess supply of imported soybeans and vinegar which can cause ordering costs and storage costs for raw materials to increase. Things like this of course need to get serious attention and handling to improve the state of production activities of the home industry XYZ so as not to cause supply costs. With this problem, a research on the cost efficiency of Tofu Raw Material production is carried out in the hope that the Home industry XYZ can optimize inventory costs. the need for raw materials for making Tofu in order to maintain quality and streamline production costs. The results of the study using the Silver Meal Heuristic method were Rp. 315,059,416 and Meanwhile, using the riil method home industry is Rp. 307,741,100, from the comparison of the Silver Meal Heuristic method with the riil home industry method, the difference is Rp. 7,318,316 and the efficiency is 2.32%.

Abstract

Biogas is an innovative product that is able to increase added value in household organic waste. Biogas is the result of the fermentation process of organic waste using Biodigester products. This service aims to help partners utilize organic waste into alternative fuels in the form of biogas. From several experiments that have been carried out, the composition of the comparison of raw materials for organic waste is 5 kg, 5 liters of water, and EM 4 500 ml. The biogas obtained is 13 psi with a long duration of use for 21.33 minutes. Biogas from household organic waste has the advantage of reducing the accumulation of organic waste and utilizing household organic waste as an alternative energy source. Energy from biogas can be used as household fuel. With the presence of biogas from organic waste, Sei Suka Deras Village has an alternative solution in utilizing household organic waste which has been a problem of air pollution, beauty and environmental comfort. Keywords: household organic waste, biodigester, biogas

Abstract

PT. Sumatra Hakarindo in its operation is not free from problems encountered such as work accidents, occupational diseases and the negative impact of the industry on the surrounding environment, so the level of human work safety as a factor of production is needed so that optimal productivity can be achieved. The application of work safety programs for workers is an important supporting effort in production activities. The work safety program system consists of several program elements and their supporters. In this study the measurement of the results of work safety efforts and the safe T value, the frequency level to express the number of accidents that occur every 1,000,000 hours worked from the employee's "work hours" home. The safe T value is a measurement that aims to compare the results of the accident reduction rate achieved for that work. From the implementation of the Occupational Health program at PT. Sumatra Hakarindo can be said to have been implemented quite well. Accidents that occurred in 2018 -2020 were 15,13,11 accidents. With a frequency rate from 2018-2020 it is 64.6; 49.9; 36,1. The severity level that occurred in 2016-2018 was 458.9; 284.2; 233,2. With a safe T value in 2018 it is known - 950.2 in 2019 it is - 1098.2. The decrease in accident rates and the severity of accidents from year to year will increase labor productivity.

Abstract

Opak Desi UKM is an UKM engaged in producing opaque crackers made from sweet potatoes/cassava. However, the work environment in these SMEs still does not have a clean kitchen standard. This clean kitchen standard is known as the GMP rules (Good Manufacturing Practice). GMP is a guideline for how to produce food with the aim that producers meet the predetermined requirements to produce quality food products in accordance with consumer demands. The problem is that the production area in SMEs is less hygienic and uncomfortable for workers and the flow of materials that occur experience cross movement, which means they intersect and also occur double tracking which causes the production process to be hampered. This research was completed using the assessment of the GMP checklist to evaluate the overall work system. The results of the checklist assessment are processed using the AHP method. The results of the assessment show that the criteria for storage and material handling with a weight of 1.65658 for UKM Opak are work system improvement priorities. Some of the proposed recommendations for improving the work system are the design of the SSOP work system, GMP, and the design of a new layout adapted to food safety and hygiene standards. The recommendations are expected to be able to increase productivity in the production process as well as safer, healthier and more comfortable working conditions.

Abstract

PT. PP London Sumatra is a factory that processes oil palm fruit into Crude Palm Oil (CPO). Oil palm fruit that comes from plantations is re-sorted by the sorting operator based on the level of fruit maturity. This sorting process is done manually using a gancu tool. At initial observation, it appears that workers have a poor working position so there is a musculoskeletal risk, so that data collection will be carried out using the Nordic Body Map Questionnaire, interviews, and documentation in the form of photos of the operator while working. Musculoskeletal risks were observed in several areas of the body, such as the back, waist, neck, upper arms, forearms, and wrists. Body posture analysis using Rapid Entire Body Assessment (REBA) and Rapid Upper Limb Assessment (RULA) methods was used in this study. The REBA method is used to analyze the lower and upper body postures, while the RULA method is to analyze the lower body postures. In the REBA analysis results obtained a score of 10 with a very high level of risk while RULA obtained a score of 7 with a high level of risk. Provision of repair solutions is carried out on sorting operators, namely changing body posture while working and suggestions for repairing work tools. At the analysis stage of improving posture, the REBA score fell to 7 with a mod.
