The indicator of sugar mill efficiency is the yield represented by sugar mill performance (technical efficiency), sugar cane plantation (sugar cane quality), and productivity. The scenario developed to formulate production process based on gap analysis. The objective of the study was to compare the production and productivity of sugar mills through improvement efficiency. The method used in this research was quantitative descriptive method, making a description of the relationship between sugar yields determinant variables, including (1) determination of gap analysis on a benchmark, (2) prediction of sugar yields and bagasse using multiple linear regression, (3) energy calculations with NCV (Net Caloric Value) approach, and (4) partial productivity measurement. The results showed that scenario 3 increased the yield to 10.4% with an increase of white crystal sugar production by 24%, while scenario 2 increased the yield to 9.3% with an increase of white crystal sugar production by 11.7% compared to scenario 1. Increasing the efficiency of milling extraction (ME) capable of increasing the energy potential of 4.3 kWh. Improving the technical efficiency of the factory resulted in increased productivity of raw materials of 0.029 tons white crystal sugar/tons, productivity of machine work hours of 5.29 white crystal sugar per work hours, sugar productivity to the land of 1.79 tons white crystal sugar/ha and energy productivity 4.27 kWh/tons bagasse (R-value as a validation test prediction model is 97.1% and 72%).
…………………………………………………………………………………………………….... Introduction:-The sugar industry is known as an industry that supplies its own energy (self-sufficiency energy) because the sugar industry produces White Crystal Sugar (GKP) as main product and bagasse as biomass. The sugar industry is known as an industry that supplies its own energy (self efficiency energy) because the sugar industry produces GKP as main product and bagasse as biomass [1]. Sugar production process in the plant through several stages including extraction, purification, evaporation, crystallization, centrifuge, drying and finishing. The inefficient process of sugar production indicates a disruption of material components and energy that come out and affect the environment [2]. The efficiency level of sugar factory is represented by the condition of factory performance. Yield, season, capacity utilization, sugar content, sugar recovery, sugarcane fiber, factory extraction reduction, reduction of overall extraction, molasses recovery are the main performance indicators for cane plant operation.
