Abstract

Latex is one of the largest sources of foreign exchange in Indonesia. The technology of stimulant etepon application and tapping frequency is one of alternative waysto increase the production.The experiment was conducted to examine the effects of different dosing of etepon and tapping frequencies on the rubber crop production.The research was conducted in PT.Agro Muko, Division II Jerinjing, Mukomuko district of Bengkulu province from July to August 2016. The method used was the randomized block design (RBD) factorial with two factors; the first factor was the etepon doses consisting of five levels: e0 = 0 cc trees-1, e1 = 0.3 cc trees-1, e2 = 0.6 cc trees-1, e3 = 0.9 cc trees-1, e4 = 1.2 cc trees-1, while the second factor was the tapping frequency consisting of three levels: f1 = frequency of 2 days, f2= frequency of 3 days, f3 = frequency of 4 days. Therefore, there were15 combinations of treatments repeated three times. The further test used was Duncan's Multiple Range Test 5%.The results showed that there was no interaction between the dosing and tapping frequency of etepon on all observed parameters. The effect of 0.9 cc trees-1 etepon dose was able to increase the flow rate of latex by 0.46 ml min-1and 63% fresh latex volume, while the tapping frequency on f3increased latex flow rate by0.42 ml min-1and fresh latex volume by 859.8ml.In the dry rubber content parameters, the etepon dosing at 0.3 cctrees-1 produced 38.07%. On the other hand, frequency of 4 days tapping resulted 37.44% less than other treatments.
