Abstract

Based on calculations by the Directorate General of Food Plants (Ditjen TP), Ministry of Agriculture. Corn production in the last 5 years has increased by an average of 12.49% per year. According to the Secretary of the Directorate General of Food Crops of the Ministry of Agriculture (Kementan) Maman Suherman in 2019 maize production is estimated to reach 33 million tonnes of dry shell (PK) in an interview with Republika on January 6, 2019. Cepiring sub-district, Kendal district, apart from being planted with rice in the rainy season, rice fields also planted with maize. After harvesting, the corn that has been plucked is separated from the cob using a corn sheller. The shelling machine is used using diesel fuel and electricity, with workers standing for long periods of time, causing fatigue in the arms, waist, thighs and back. The data processing of the nordic body map questionnaire was carried out to determine the complaints on the skeleton and muscles of the workers. From the results of the questionnaire above, most Sido Rejo farmers feel complaints on their right shoulder, left upper arm, back, right upper arm, back, waist, left elbow, right elbow, left forearm, right forearm, left wrist, wrist right, left hand, right hand, left thigh, right thigh, left calf, right calf, left leg to right leg. With anthropometric measurements, the dimensions of the body used are the height of the sitting shoulders and the data used are the average data or the 50th percentile. With this solar sheller, it can save fuel and be environmentally friendly and reduce the complaints of the frame and muscles of farmers

Abstract

The problem that often occurs in people who use semi-jet water pumps is that when the installation of the water pump has been completed, it turns out that the water discharge cannot flow as expected and the electricity consumption is quite large. This research is expected to get optimal results, when installing the water pump installation, it is expected to get the largest water discharge by varying the valve location with the in-late angle, so that it will reduce the time to use the water pump. The experimental results with the linear regression method show that optimal conditions are achieved at variation 8 meaning to maximize the water discharge at the semi-jet water pump, namely the location of the valve above with an in-late angle of 450. The results of the comparison between the average value of water discharge for general use conditions are 29 .6 liters/minute with an average value of water discharge under optimal conditions of 34.8 liters/minute, indicating that the value of water discharge under optimal conditions can increase the water discharge by 5.2 liters/minute = (34.8 liters/minute – 29 ,6 liter/minute), so there is an increase of 8.0745 % = { [5,2 / (34,8+29,6)] x 100%}.
