PENGURANGAN KADAR AIR OPTIMAL (MOISTURE CONTENT) BLANKET SIR 10 MELALUI PROSES MATURASI DI PABRIK PENGOLAHAN KARET

Natural rubber processing is one of the potential agro-industrial sectors for Indonesia, whose role quiteimportant as a foreign exchange earner plantation sub-sector. The production rate 1.6 million tons in2002 or 22% world's total natural has placed Indonesia second largest producingcountry after Thailand. This study aims to determine whether quality blanket sir 10 optimal by using amaturation time 11 days, which related to: Decreasing Blanket Moisture Content with Maturation Method,Analysis Sample Data, Water Content, MaturationProcess. method this research was carried out in crumb factory researchdesign: Bound variables Rubber sheet / and from factory, theindependent were follows: treatment: hanging, maturation time: days.The weight samples I, II, III, IV 975.90 kg, water content evaporated 8.85 kg theamount shrinkage 0.91%. amounted 0.91%, totaldecrease moisture eleven (11) days maturation. process maturing takes placenaturally. From data analysis discussion reducing processingmaterial SIR (Standard Indonesian Rubber) Low Grade Crumb Rubber, it concluded, Using4 (four types initial weight: 20.15 kg) (sample 1), 20.85 2), 24.90 (sample3), 27.85 4).
