Abstract

Rubber plant (Hevea brasiliens) is an important plantation crop, both in the context of the community's economy and as a source of non-oil and gas foreign exchange for the State. This study aims to determine the level of plasticity index determination of Indonesian rubber standards. This research was conducted in February 2020 at the UPTD BPSMB Laboratory of the South Sumatra Province Trade Office using the Plasticity Retention Index (PRI) Determination evaluation method. The results of the Retention Index Determination Test (PRI) found that test Number 1 initial plasticity (Po) with a median value of 52.0 mm, number 2 initial plasticity (Po) with a median value of 53.0 mm, Number 2 Number 1 initial plasticity (P30) with a mean value of 38.0 mm, number 2 initial plasticity (Po) with a mean value of 39.0 mm.
