Abstract

ABSTRACT Empty fruit bunches are excessive wastes in oil palm plantations. There are about 22 - 23 percent of empty fruit bunches produced from the processing of oil palm seeds. While these bunches are simply dumped around the plant, it can be used as a compost in agricultural practices. Research of the utilization of empty fruit bunches of oil palm as compost to Aloe vera plants combined with potasium fertilizer (KCl) was conducted in the greenhouse at the University of Bengkulu. The objectives of the research were to determine the growth responses of Aloe vera plants to the compost of empty fruit bunches of oil palm with the combination of potassium fertilizer. After twelve weeks of experiments, results showed that there was no significant response of Aloe vera plants to the combination of the compost of empty fruit bunches of oil palm with KCl fertilizer. However, the compost of empty fruit bunches itself affected leaf area and leaf fresh weight significantly. Compared to the control that only produced 11.16 gram fresh weight leaf-1, the compost of empty fruit bunches at 10, 20, and 30 tons ha-1 increased the leaf fresh weight by about 17, 55, and 28 %, respectively. The increased leaf fresh weight was certainly due to accretion of leaf area by 11, 38, and 16 % at the dose levels of compost of empty fruit bunches of oil palm at 10, 20, and 30 tons ha-1, respectively.
