Abstract

One of the problems with palm oil mill waste is the management of Oil Palm Empty Bunches (OPEFB). One method that can be used for handling OPEFB waste is by converting it biologically to green fertilizer. The method used in this research is observation and descriptive analysis methods for each treatment. The length of the study was 28 days. The tools used were a hoe, bucket, watering can, and a place for vermicomposting. Testing equipment includes scales, pH meters and calipers. Material used was palm oil waste (sludge, solid, and empty bunches). The treatment carried out was to composite 3 materials - palm oil waste materials with a proportion of 100%, 50%, and 25%. The composite was then given 500 grams of Lumbricus rubellus worms per treatment. The parameters measured were the decomposition rate, pH, characteristics of the worms which were observed every 7 days up to 28 days. The rate of decomposition of organic matter received the highest response in the mixing treatment of L6 (65%) and L7 (88%) media. The decomposition process did not affect the pH of the media. The average pH obtained was 6. The process of decomposition rate and media pH did not affect the characteristics of Lumbricus rubellus worms. The growth of the worms increased, which is presumably because the media conditions were suitable for their survival.
