Abstract


A. Wijaya, A. Rachmawan, S.A. Pasaribu. 2018. Latex Characteristic and Rubber Properties of IRR 400 Series Clone. Rubber cultivation (Hevea brasiliensis) in Indonesia using grafted techniques (also known as clonal plants) have been done since in 1916 to obtain high productivity and latex quality for the rubber industry. This study aimed to investigate the latex characteristic and rubber properties from selected clones. The clones were IRR 425, IRR 428, IRR 429, IRR 431, and IRR 434. Latex was collected from some rubber trees which had a d/2 tapping frequency system on BO-1 panel and then it was analyzed in accordance with Standard Indonesian Rubber (SIR) spesifications. Rubber compound also was prepared using ACS-1A to find out physical properties of each rubber clone. The result showed that IRR 425 had the highest of dry rubber content about 36,11% whereas IRR 428 was found to be lower about 27,45%. Rubber properties of IRR 429 showed good values in modulus 300%, tensile strength, elongation, tear strength, and hardness i.e. 2,15 Mpa, 17,20 Mpa, 680 Mpa, 40,47 Mpa, and 41, respectively. All rubber clones fulfilled the spesifications for SIR 10.
