Abstract
A series of tests were already carried out at an open laboratory to simulate the utilization of tidal or river current to couple the spiral pump to lift u p the water to farm areas of about 2- 4 meters above the water l e v e l . The tests were conducted on two wheels with coils of different diameters. The first wheel of 46 cm diameter ; 6.6 mm coil pipe diameter; overall length of coil 19 meters; number of wound 16 th, the highest head achieved 4 meters. The second wheel o f 4 6 c m diameter; 8 . 1 m m coil pipe diameter; overall length of coil 14.3 meters; number of wound 13th; the highest head achieved 5.68 meters. The results comparation shows the efficiency of spiral pump proportional to the pipe diameter size. The smaller the diameter of pipe, the lower the efficiency . Keywords: Spiral pump, River current, Efficiency decrement I. INTRODUCTION Most farmers in Indonesia utilize the Diesel engine to pump the water to the farm areas mainly in summer. It needs energy and cost, depending on how big the area is, the kind of crop and the length of the dry season. [1,5]. Watering the farm areas by engine creates the problem of production cost higher than normal. The farmers rent the engine and pay the energy for running. This cost is lowering the benefit of farm and reducing the spirit of farming o f the people in Telang II – Banyuasin. This effect is predicted also happen in other swamp farming areas in Indonesia. Lifting the water from the irrigation canal to the farm area of about 2– 4 meters above the canal becomes serious challenge for farmers in order to minimize the energy and cost. Free energy is required to reduce the production cost at the common farm yield. This matter becomes interesting to persuade farmers continually in planting the rice and combat the change of farm land use into industries or settlements [1,5]. It is around 100 thousand hectares of Indonesian agriculture land area converted into industrial and residential per year[2], which are unwanted by the government. This research was trying to find the utilization of local river and tidal current in form of the simulation. The use of local river and tidal current were predicted would reduce significantly the farming production cost and increase the farmers benefit. The spiral pump usage was ecology friendly and decrease the national fuel consumption
