Abstract
The objective of this study was to evaluate performance of LPG-fueled single cylinder pump engine in utilizing shallow groundwater for rice field irrigation. Research was conducted in Baktirasa Village, Subdistrict of Sragi, Regency of South Lampung during planting session of September–December 2015 by observing and analyzing technical and economical performance of LPG-fueled pump engine. Observation was performed on the depth of groundwater before and after pumping, pumping duration, discharge, LPG consumption, and depth of standing water. Irrigation cost was evaluated using local prices for installation and manpower. Results of the research showed that shallow groundwater is potential to be explored as a source of paddy field irrigation. Depth of water table was substantially low at 3.41 m and decrease to 4.83 m after continuous pumping for about 6.5 hours. The LPG-fueled pump engine worked smoothly at an average gas consumption of 0.464 kg/h with a field capacity of 0.0190 ha/h and a discharge rate of 14.58 m3/h. The distribution uniformity of 92.28% was achieved with average depth of standing water of 4.12 cm. The cost of irrigation operation was IDR 226,875.23/ha, lower than leasing one (IDR 400,000.00 /ha).
