Sugarcane (Saccharum officinarum L.) is an important commodity as the main ingredient for sugar production. Good sugarcane growth will produce high sugar yields so that sugar production also increases. Seed maintenance is one of the important stages in preparing good plants, especially fertilization. Oil palm empty fruit bunches residual mushroom (TKSJ) are one of the solid wastes produced from processing palm oil mills and can be used as an organic fertilizer. The purpose of this study was to determine the effects of giving TKSJ on the growth of sugarcane seedlings in peat soil media. This study used a completely randomized design (CRD) consisting of 5 treatments and 5 replications, namely without TKSJ compost (K0); TKSJ 25% (K1); TKSJ 50% (K2); TKSJ 75% (K3) and TKSJ 100% (K4). Observation parameters consisted of leaf length (cm) and root wet weight (g). The data were analyzed by Analysis of Variance (ANOVA). If it has a significant effect, then it is continued with Duncan's Multiple Range Test (DMRT) at a level of 5%. The results showed that composting of TKSJ could increase leaf length and root wet weight of sugarcane.

Most of the people in Delta Pawan District are farmers and breeders. The number of agricultural business households in Delta Pawan District is 354 cultivating food crops, 640 cultivating horticultural crops and 786 breeders. This shows that the availability of raw materials for making organic fertilizers is very abundant. The problem that has occurred until now is that the waste from agricultural and livestock products has not been utilized optimally by the community due to limited tools and knowledge in processing it into organic fertilizer. The purpose of this activity is to provide motivation and knowledge to the residents of Kalinilam village to utilize agricultural and livestock waste into organic fertilizer which is abundantly available. The method used to overcome these problems is to provide training to Kalinilam villagers on how to process agricultural and livestock waste into organic fertilizer using a compost chopper. This service activity will be carried out in July 2024 with 2 stages, namely socialization and counseling as well as training and assistance in making compost. The result of the service of this training program is an increase in the knowledge of villagers about processing agricultural and livestock waste into organic fertilizer so that it can increase the utilization of waste into more useful products
