Abstract

Pump is mechanical device to increase the pressure energy of a fluid. Generaly pumps are used to lift the water from low level to high level. These are of two types,namely reciprocating pumps and centrifugal pumps. On centrifugal pumps the centrifugal force or variation of pressure due to rotation is responsible for their operation or working. The program of community services as implementation of sciences and technology intended to introduced and give skill training about water supply units to the community at Desa Sempa jaya ,Kabupaten Deli-Karo. In this area the people have a problem about availibity of water for agricultute, when mountain Sinabung gets eruption the leave of plantation are covered with dust and damaged to citrus plants,in dry season orange plants lack of water even though the success of the harvest is very dependent on water. The program was carried out by designing, fabricating and erecting the unit of water supply,consist of deepwell pump,piping system, valve,tee,bent,tower tank and panel control. The result of this community services showed that the capacity of pumps are 6 liter/menit,head are 50-70 meter,power 2 HP,speed 1500 rpm.capacity of tower tank 5400 liter, the pump may supply the water to tower tank until full about 2 hours,and the farmer may use the water from the tower tank by gravitation about 3 days.

Abstract

Topographically, the Mandailing Natal district is divided into lowland areas which are coastal areas with an elevation of 00 -20 covering an area of ​​160,500 Ha (24.24%). One of the drivers of economic growth in Mandailing Natal district is plantations. Plantation plants in the Mandailing Natal district can develop coffee, cinnamon, coconut, candlenut, sugar palm, and cloves. However, the level of absorption of agricultural technology is still not as expected, especially for coffee farmers in Gunung Tua village, Mandailing Natal Regency, making coffee productivity from this area less than optimal. From the survey results and discussions with coffee farmer partners in the town of Gunung Tua Mandailing Natal, it was found that there were several problems in the post-harvest process, and one of them was the peeling of the coffee bean skin. So far, most coffee farmers use a coffee peeler manually with a 20 kg/hour capacity and require quite a high operational cost. Therefore, the service implementation team and coffee farmer partners agreed to make a 100 kg/hour coffee peeler machine and an electric motor drive based on these conditions. Test data in the field shows that for a coffee peeler with a capacity of 100 kg/hour, only one liter of fuel is needed to peel 400 kg of coffee beans. This, of course, makes a significant reduction in production costs in the post-harvest process. It is hoped that this machine can work optimally to reduce the production cost of coffee peeling and increase the income of coffee farmers in the village of Gunung Tua Mandailing Natal.
