Physical and Chemical Properties of Various Products of Composting Process on Palm Oil Middle Waste

摘要

Many oil palm plantation produce organic waster. The processing of soild organic waste such as oil palm plants is by composting, because the process is quite easy and the cost is relatively cheap. Determine the decomposition rate of the oil palm midrib by using tipes of bioactivator. Different types of bioactivator affect on the rate of decomposition in the midrib of oil palm plants. The purpose of the study was to determine the physical and chemical properties of oil palm fronds in various composting processes. The research was carried out from April to June 2019 in the Soil Science laboratory, Faculty of Agriculture, Mulawarman University, Samarinda. Descriptive research consisted of five types of composting treatment and each treatment was repeated five times, namely: oil palm midrib compost (p0), oil palm midrib compost with vegetable waste bioactivator (p1), oil palm midrib compost with golden snail bioactivator (p2), oil palm midrib compost with pineapple bioactivator (p3) and oil palm midrib compost with EM-4. The research implementation activities are as follows: (1) collection of materials used, (2) manufacture of activator, (3) manufacture of compost, (4) analysis of several physical and chemical properties of various composting treatments in the laboratory. The results showed that: (1) oil palm fronds required composting time of 4 weeks; and (2) the results of composting oil palm fronds waste with a bioactivator (golden snail or pineapple) and composting with EM-4 are better than ordinary composting and composting with vegetable waste bioactivator.
