Municipal solid waste and agricultural waste have different ratio C/N and nutrients contents. They can be used as compost row materials. The purpose of the research was to get an optimum combination of both wastes to improve compost quality, to meet the Indonesian National Standard 19-7030-2004. Composting process use pots. The treatments were twelve combination of municipal solid waste (garbage market, household waste, restaurant waste) and agricultural waste (rice straw, empty fruit bunches of oil palm, cassava peel, banana skin) with a ratio of 1:1 and enriche by chicken manure, cow manure, wood ash and cellulolytic microorganisme. The treatment were replicated three times. The results showd that the nutrients content of compost were 0.77 to 1.19% nitrogen, 0.23 to 0.30% phosphorus, 0.46 to 0.69% potassium and 15.48 to 34.69% organic matter. The combination of agricultural waste and municipal solid waste affected the quality of compost. Compost that meets SNI 19-7030-2004 is a combination of rice straw+market waste that contains 1.12% nitrogen, 0.28% phosphorus, 0.63% potassium, ratio C/N 19.50, pH 7.42, and organic matters 37.65%.

Red pepper production in 2016-2017 was increased. Although production has increased, demand for pepper will continue to increase, and efforts to increase soil fertility still need to be sought. To maintain and increase soil productivity, a combination of inorganic fertilizers with appropriate organic fertilizers is needed. One of the organic fertilizers is biofertilizers. This research aimed at finding out the formulation and dosage of biological fertilizers consortium of cellulolytic bacteria based on organic liquid waste that was appropriate for the growth and yield of red pepper plants. This research method used a Completely Randomized Design with 12 treatments, namely (5, 10, 15) ml of biological fertilizer of waste water washing rice, (5, 10, 15) ml of biological fertilizer of coconut water waste, (5, 10, 15) ml of biological fertilizer of tofu water waste, (5, 10, 15) ml of palm oil liquid fertilizer. The results showed that all biological fertilizer application based on organic liquid waste cellulolytic was able to give varied results on each parameter observed so that all wastes could be applied to pepper plants. Tofu wastewater biofertilizer with a dose of 10 ml give a good response to the production of pepper plants compared to other treatments.
The low productivity of paddy in Langsat Permai Village, Bunga Raya District, Siak Regency, one of them is causes the unavailability of sufficient water for crop cultivation, so it is necessary to do water management by making canal blocking to be used on rice plants in the area. This is done to meet the water needs of rice plants during the dry season. Therefore, assistance is provided through water management in Langsat Permai Village, Bunga Raya District, Siak Regency. Mentoring strategies are carried out by discussing directly with farmer groups about the impact of making canal blocking. Through this activity, the availability of water for rice plants during the dry season is fulfilled. Production of 1 Ha of rice before the blocking canal produced 4-5 tons/harvest to 6-7.8 tons/harvest after the canal blocking.
