การลดความสูญเสียโดยไม่ทราบสาเหตุในกระบวนการผลิตน้ำตาลทรายของโรงงานน้ำตาลเกษตรผลจำกัด จังหวัดอุดรธานี Reduction of Undetermined Loss in Sugar Production Process of Kasetphol Sugar Factory, Udonthani Province

Abstract

This article aimed to identify activities in the sugar production process, measure the undetermined losses in the process, and propose ways to reduce the undetermined losses in the sugar production process of Kasetphol Sugar Factory Limited, Udonthani. Using focus group method to collect data from 20 key informants, data collected were then analyzed using IDEF0 and tree diagram with Why-Why and How-How methods of data analysis. The study identified seven activities in the sugar production process include Sugar Cane Inspection, Juice Extraction, Evaporations, Crystallization, Centrifugal, Storage and Delivery of Finished Product. When measuring losses in the production process from the beginning until midseason of sugar production, results showed; the average losses from green tips and leaves of sugarcane 6.5 percent, losses during transportation 0.15 percent, and soil 1.48 percent, sugar syrup leakage 0.3 percent, sugar dropped 0.65 percent, and other processes 3.85 percent. The study proposed four approaches to reduce undetermined losses in the sugar production process starting from losses due to sugarcane falling during transportation, losses due to contamination, losses from leakage during sugar processing, and the losses from transportation. The implementation of these four approaches result in reduction of undetermined losses as following; reduction in losses from contamination by 59%, while the losses from transportation activities was reduced to 35%, and the losses from leakage during sugar processing was reduced up to 70%. The result of this study led to proper solution to reduce the undetermined losses in the sugar production process for Kasetphol Sugar Factory Limited, Udonthani.
