The Proces of Separation of Liquid Nira from Impairs (Purification) to Become a Raw Material for Sugar at the Gula Candi Baru Factory

The aim of this observation is to understand the process of making sugar from sap to crystal sugar. This observation process was carried out at the Candi Baru Sugar Factory, Sidoarjo, East Java. The sugar making process starts from the milling station, refining station, evaporation station, cooking station and finishing station. At each station, the quality of the sap is first analyzed in a quality assurance laboratory to maintain good quality. At the purification stage, it is hoped that the juice can be cleaned from impurities, therefore the parameters of Brix, pol, temperature, pH, color balance, phosphate content, sulfur content, turbidity must be analyzed and informed to the production department to find out what needs to be repaired and what does not need to be repaired. so that the quality of the crystal sugar products produced remains guaranteed. Highlights: Quality assurance: Regular analysis of sap quality ensures consistent production standards. Purification stage: Vital parameters such as Brix, pH, and color balance are monitored for impurity removal. Product quality: Maintenance and adjustments based on analysis ensure high-quality crystal sugar output. Keywords: Crystal Sugar, Cane (Saccharum officinarum L), Crystallization
