Pengaruh Konsentrasi Ekstrak Buah Belimbing Wuluh (Averrhoa bilimbi) sebagai Koagulan Alami terhadap Karakteristik Karet Klon PB 260

Averrhoa bilimbi is a plant rich in benefits, one of which as natural coagulant. The aim this research to increase the potential an environmentally friendly coagulant for coagulation rubber clone PB 260. concentrations used were 45%, 55%, 65%, 75% and 85%. characteristics tested dry content (DRC), initial plasticity (Po) Plasticity Retention Index (PRI). Based on results study, optimum concentration 85% latex time 11 minutes with 33% DRC, 41% Po 97% PRI. highest used, faster process occurred. 2% formic acid was chemical comparison. From it can be concluded that producing equal quality ones using meets Indonesian Rubber Standard SNI 06-1903-2000.
