Abstract

Indonesia has the largest rubber plantation area in the world but its productivity is still lower than Thailand. The use of stimulants is one of an alternative to increase production on rubber. One of the potentially stimulant materials is Polyethylene Glycol (PEG). The purpose of this study was to determine the effect of stimulation of various concentrations of PEG on latex rubber plant yields and get the best concentration of PEG that can improve the latex result. This research was conducted in Desa Betung Island, Pemayung District, Batanghari for one month from May 2017 until June 2017. This study used non parametric field design consisting of 6 treatments that is without stimulant (k1), concentration of 1.5% PEG (k2), 2% concentration of PEG (k3), 2.5% PEG concentration (k4), concentration 3% PEG (k5) and concentration of 3.5% PEG (k5). Treatments were given to randomly selected rubber plants based on their age and girth. To test the median value of treatment effect, the researcher used H Kruskal Wallis test then continued with Paired T-Test Test. The result showed that PEG stimulation in rubber plant can increase the yield of latex volume, latex weight, weight of rubber material and dry rubber content. PEG stimulant concentration at 2.5% concentration was the best result with mean of latex volume 59,17 ml, weight of latex 69,17 g, weight of 51.67 g and KKK 42,99%.
