Agroforestry contributes to addressing the problems the world is facing today. Regarding economic well-being, agroforestry can increase diversify farmers’ incomes and allow them to have access to more nutritious food. The community of Pematang Sidamanik Sub-district conducted an agroforestry pattern that combined forestry crops with various crops. This research aimed to examine the practice of agroforestry. Methods of data collection were interview techniques and field observation (survey). Data processing was qualitative descriptive analysis method. Cultivation techniques for T.sureni in study site are the provision of seeds, maintenance, and harvesting simply done by the community. Suren tree is used as a raw material for building, furniture, ships and canoes, while suren leaves are used as vegetables, medicines and organic pesticides/insecticides. Agroforestry practices are influenced by the land and tree tenure system (private or state-controlled) that farmers operate. Tenure affects the decision of farmers to make about the kind of agroforestry system they can use.

Activator in compost has key role to get soil nutrient more nutritious. Compost is one of organic material that help environment keep always good. This study was conducted to determine the effectiveness of Stardec and EM4 using cow feces, chicken manure, rice straw, palm fronds and palm leaves. Compost is one type of organic fertilizer derived from plant and animal waste which is very useful for improving nutrients in the soil. Most farms in Indonesia do not use waste such as animal manure to be used as compost. The research was conducted anaerobically, by analyzing N, P, K, water content, C/N ratio, pH, and temperature. The research design used was a completely randomized design (CRD) with a 7-day fermentation treatment and the provision of different activators, namely stardec and EM4. The results of this study indicate that compost using Stardec and EM4 activators showed levels of NPK, pH, Temperature met the standards for nutrient content, as well as physical quality.

The study aims to determine the effect of the utilization complete feed fermented based waste peel cassava (Manihot esculenta Crantz) on carcass characteristics and non carcass male kacang goat.This study uses a completely randomized design method (CRD) with 4 treatments and 3 replications.The diets used in this research was complete feed fermented with different percentage of cassava peel, among others P0 (cassava dried 75 % and cassava peel 0 %), P1 (cassava dried 55 % and cassava peel 20 %), P2 (cassava dried 35 % and cassava peel 40 %) and P3 (cassava dried 15 % and cassava peel 60 %). The variables observed in this study include slaughter weight, carcass weight, non carcass weight and carcass percentage.The results obtained in this study indicate that utilization of complete feed fermented based waste cassava peel was not significantly different (P> 0.05) on slaughter weight, carcass weight, non carcass weight and carcass percentage.The conclusion of this study is utilization of complete feed fermented based cassava peel waste does not affect the characteristics carcass and non carcass.
