Abstract

Rubber is one of Indonesia’s main commodities resulting in a considerable number of people relying their incomes as rubber farmers. However, unstable rubber price proves to be a problem for these farmers. One solution to be offered is an alternative natural coagulant which is easily obtainable and able to produce good quality rubbers. Averrhoa bilimbi with its known acidic properties shows a prospect as a natural coagulant. This study aims to determine the effect of variation in the concentration of Averrhoa bilimbi extract on the characteristics of rubber clone IRR 118 as well as the advantages and disadvantages of using the extract as natural coagulant. The rubber clone used was IRR 118 with various Averrhoa bilimbi etracts of 20%, 40%, 60%, 80% and 100% and 2% synthetic chemical coagulant formic acid as comparison. The coagulant volume was 20 ml for each concentration and the volume of latex used was 100 ml. The characteristics of the rubber tested were TSC, DRC, Po and PRI. The results showed that the highest value of dry rubber content (DRC) was at 100% natural coagulant concentration which is 34% with a total solid content (TSC) value of 37% while the highest Plasticity Retention Index (PRI) value was at 100% concentration, which is 92%. This study exhibits the use of natural coagulant from Averrhoa bilimbi has met the Indonesian Rubber Standard SNI 06-1903-2000. Therefore, Averrhoa bilimbi extract can be used as an alternative coagulant for rubber latex.

牛角提取物作为天然混凝剂对橡胶性能的影响

橡胶是印度尼西亚的主要商品之一，导致相当多的人依靠橡胶农民的收入。然而，不稳定的橡胶价格对这些农民来说是一个问题。提供的一种解决方案是一种可替代的天然混凝剂，这种混凝剂很容易获得，并且能够生产出高质量的橡胶。牛角草因其已知的酸性而显示出作为天然混凝剂的前景。本研究旨在确定不同浓度的牛角草提取物对橡胶克隆物irr118特性的影响，以及使用牛角草提取物作为天然混凝剂的优缺点。橡胶克隆为irr118，分别以20%、40%、60%、80%、100%的黄花蒿提取物和2%的合成化学混凝剂甲酸为对照。混凝剂体积为20 ml，所用乳胶体积为100 ml。所测橡胶的特性为TSC、DRC、Po和PRI，结果表明，在100%天然混凝剂浓度时，干胶含量(DRC)最高，为34%，总固含量(TSC)值为37%，而塑性保持指数(PRI)值在100%浓度时最高，为92%。本研究表明，天然混凝剂的使用达到了印尼橡胶标准SNI 06-1903-2000。因此，牛角草提取物可作为胶乳的替代混凝剂。
