Abstract

Flouration of porang tuber chips is one of the efforts to extend the shelf life and is one way to facilitate the processing of food made from porang tubers. The method in this study was porang chip flouring with a thickness of 1, 3, and 5 mm using a hammer mill with clearance distance of 15, 10, and 5 mm. The flouring process for porang tuber chips was repeated 3 times for each thickness with a weight of 1 kg each. The purpose of this study was to determine the effect of the thickness of the porang tuber chip and the distance between the tip of the hammer mill hammer with a sieve (clearance) on the milling time and working capacity of the pulverizing machine and analyze the uniformity index and degree/modulus of fineness resulting from the milling. The results in this study are the thickness of the porang tuber chip and the clearance distance affect the working capacity and milling results, while the uniformity index is not significantly different and the degree of fineness produced falls into the same category, namely the thicker the chip used, the longer the milling time but the results the smoother the grinding, the smaller the clearance, the less time is used for grinding and the more results milling obtained. The use of the best hammer length hammer mill is using a hammer length of 85 mm, the working capacity is greater and the results obtained are more and smoother flour and the remaining flour is also less than using a hammer length of 75 and 80 mm.

Abstract

Agricultural machine tools with technology can help processes in agriculture so that time is more effective, cost-effective and improves the quality or quality of plants or products, such as vacuum frying which is used to fry fruit chips that are susceptible to hot temperatures so that the taste of fruit chips from vacuum frying will be similar to the original fruit. The use of agricultural tools and machines cannot be separated from K3 and ergonomics. Therefore this research was conducted for the ergonomics of a vacuum fryer in terms of anthropometry, recommended workload, work fatigue, and the physical work environment. This study used a quantitative method supported by literature studies on the ergonomic dimensions of a vacuum fryer or in accordance with the size of the human body. The results showed that the ergonomic dimensions of the tool corresponded to the dimensions of the operator's body in the form of control box height, stove height, frying tube cover height, pressure output height, pressure regulator height, and stirrer lever. The level of operator fatigue is classified as ergonomic because the CVL (Cardiovascular Load) percentage obtained is ≤ 30% so that fatigue does not occur in operating the tool. The recommended workload is classified as ergonomic because the actual load lifted is lower than the RWL calculation results. The temperature measurement is not ergonomic because the temperature exceeds the NAV, while the lighting is classified as ergonomic because it has exceeded the minimum standard value for lighting and the noise measurement is classified as ergonomic because it does not exceed 88 dBA. In operating a vacuum fryer, it can be done in the morning or there is a work station repair so that glare does not occur when using the machine, and when using it, it must be equipped with personal protective equipment (PPE). Keywords: Anthropometry, Ergonomic, Vacuum Fryer

Abstract

Activities in agricultural machinery workshops must concern with Occupational Health and Safety (OHS), especially the physical conditions of the work environment. There are potential physical dangers, especially noise from machines in the workshop. This research aims to analyze the noise level at the UPTD Agricultural Machinery Workshop, Main Center for Food Crops and Agricultural Machinery, Lampung Province, and provides recommendations for control engineering. The parameters observed in the research were noise, temperature and humidity. Noise level was measured by using a sound level meter for the source of the sound when the machines were turned on, at fifty measurement points determined based on applicable regulations. Temperature and humidity were measured using a digital hygrometer thermometer, at three observation points. The measurement results were compared with the applied quality standards in Indonesia. Noise measurement resulted (88.29 ± 11.58) dBA, with 7 sound sources turned on simultaneously. Based on Minister of Manpower Regulation No. 5 of 2018, at this noise level the maximum exposure time for workers is 4 hours per day. If the time limit exceeds, workers must use ear protection or do the job in rotation (in shift work). Average temperature measurement resulted (28.8 ± 0.3)°C and average humidity measurement (61.5 ± 7.8)%. Referring to the Decree of the Minister of Health of the Republic of Indonesia No. 1405 of 2002, the air temperature and humidity at the UPTD Agricultural Machinery Workshop, Main Center for Food Crops and Agricultural Machinery, Lampung Province is still above the requirements for working environmental health. Keywords: Ergonomics, Noise, OHS, Physical Environment, Potential Physical Hazards.
