Audit energy is an appropriate method to determine the energy consumption expended ineach agricultural cultivation activity, thereby reducing the wasteful use of energy. Energyconsumption in rice cultivations consists of humans, fuel, machinery, seed, fertilizer andpesticides. The objective of the study was to analyze the total energy consumptions in theform of an energy audit activity on lowland rice cultivation in West Sumatera Indonesia. Itis important to do, because of much energy input excessed, but less on productivity. So,by using analysis energy expenditure, productivity can be optimized with fixed inputenergy the costs could be minimized. Energy inputs were measured during all operatingactivities in rice cultivation (seeding, tillage, planting, fertilizing, spraying, weeding andharvesting). Energy input analysis based on energy sources used was divided into sixparameters, namely: engine energy, fuel, humans, seeds, chemicals (pesticides) andfertilizer energy. The result showed the average of the total energy inputs in this study was16,816,612 MJ/ha distributed to human, fuel, machinery, seeds, fertilizers and pesticidesenergy respectively 216.39; 890.75; 60.02; 983.29; 14,207.54; and 458.60 MJ/ha.Production costs incurred in rice cultivation activities in this study were IDR 13,107,562/ha. Finally, the rice yield prediction model based on the input energy are Y1 = 4786.56 –28.29X1 + 36.23X2 - 24.73X3 - 8.43X4 + 0.06X5 - 0.80X6 and Y2 = 3605.11 + 5.44X2. Thedata of total energy were needed as a recommendation for the government to balanceenergy input and output on rice cultivations.
