The aim of this investigation is to determine the performance of productivity and feasibility of the operation of glucose syrup plant based on Energy Productivity Ratio (EPR). EPR is expressed as the ratio of output to input energy and by-product. Glucose syrup plant is to process dregs of sago to become glucose product. The procedure starts from collecting data needed as input energy such as: dregs of sago prices, energy demand and the depreciation of the factory. The output energy and its by-product comprise the whole production process such as: glucose syrup price and the remaining product calcium chloride. Calculation the equal energy of glucose syrup is to analyze the value of Energy Productivity Ratio (R) based on processing capacity per year, the value of EPR was 2,19 and 4,47 (EPR > 1), which indicated that the processing dregs of sago to glucose syrup is reasonable to be operated based on the energy productivity.
