Purpose to examine the influence of aktivator nature in accelerate the process of the dregs of the aren decomposition, observing the activity and changes of the dregs of the aren compost during the decomposition process within four week and to get a quality dregs of the aren compost which is appropriate with SNI (Standar Nasional Indonesia). This research was done from march - April 2016, the study was conducted 2 stages, namerly an early stage for 30 days and late stages of over 30 days. Experiment arranged in Completely Randomized Design (CRD) single factor with 4 treatment: manure rice straw compost and without activator. Each treatment repeated 3 times so there are 12 experiment units. Data collection is done by obseving the decomposition. The observed parameters included physical axamiation (temperature, color, odor, moisture content and partcle size) and chemical axamonation (pH,C organic, content BO, content N total, ratio C/N). If the data of compost analysis the dregs of the aren in the early stages show no real difference and not comply with SNI compost, it will be continued in the composting process to the final stage. In the final stages, the treated treatments and the number of replicates are all the same, except the weight the dregs of the aren waste. The results of the research showed that the addition of the manure activator, the old compost of rice straw, stardec and control give a real effect to the quality of the compost the dregs of the palmsugar. but the best treatment of the quality of palm sugar compost is Stardec treatment. The manure activator treatment is the best for decomposing waste palm sugar.
