LIVESTOCK MANURE WASTE POTENTIAL AS COMPOST FERTILIZER

By: Badariah, Dori Fitria and Andriyan Saputra

Compost fertilizer is a fertilizer that originated from organic substances’ decomposition by microorganisms (Warjoto et al., 2018). Organic compost fertilizer is useful to improve soil fertility, as a soil aggregate stabilizer, nutrient source for soil and plant as well as improving long-term soil productivity (Puspadewi et al., 2016). Compost fertilizer could be made in an aerobic and anaerobic environment. Aerobic compost is produced from organic substances’ decomposition in the presence of oxygen (air) that produce the main product which is carbon dioxide, water, and heat. The compost-making process could be done by adding a bio activator that plays a role to decompose organic matter into elements of N, P, K, Ca, and Mg which are returned to the soil, and CH₄ and CO₂ nutrients that could be absorbed by plants (Rahmawanti & Dony, 2014).

Unutilized farm and agricultural waste would have an impact on the environment. Those impacts could be in the form of air, water, and soil pollution, become a source of disease, and could spur the increase of methane gas and disturbance to comfort and aesthetics (Ratriyanto et al., 2019). A cow would produce 8-10 kg of feces a day or 2,6-3,6 tons a year, or equal to 1,5-2 tons of organic fertilizer (Marina et al., 2021). This would reduce the use of inorganic fertilizers and speed up the process of improving agricultural land. Farming results in the form of livestock manure could be utilized as organic fertilizer. Organic fertilizer has the benefit to improve environmental support, increase plant production, increasing farmers’ income, and reducing environmental pollution effect (Nenobesi et al., 2017).

Sungai Telang Village, Bathin 3 Ulu Subdistrict, Bungo Regency has the potential as an agricultural products producer such as fruits, vegetables, and paddy. Furthermore, the farmers also have buffalo, cow, goat, and chicken farms as additional income. Farm businesses produce waste in the form of livestock manure that could be utilized as organic fertilizer. Livestock manure utilization at Telang Village is rarely done because of the lack of resident’s knowledge regarding manure management. Whereas livestock manure could be utilized if processed to become organic fertilizer that is used for agriculture businesses.

These service activities aim to give knowledge and understanding about the livestock manure’s potential as compost fertilizer to increase Telang Village community agriculture yield. These service activities were held on Tuesday, Agustus third, 2022 from 8-11.30 WIB, located at UIN Sulthan Thaha Saifuddin Jambi College Student’s Community Service Program Post, Telang Village. The method used in the service activities is socialization and demonstration which is explaining livestock manure potential theoretically and followed by composting demonstration.

Composting is started with livestock manure collection (buffalo, cow, goat, and chicken) by harvesting from the livestock cage, followed by composting process. The composting stages is as follow: 1) Prepare a tarp as a base and close the compose so rainwater does not get in; 2) Prepare a bucket, hoe, shovel, and plant watering; 3) Prepare raw material which is livestock manure; 4) Prepare husk and ash as additional material; 5) Raw material composing for composting with bottom to the top layer as following: a) 12 cm Livestock manure, b) 1 cm husk, c) 0,3 cm ash, 4) 4 liter em4 probiotics watering 6) All materials are mixed evenly and then covered and stored in a place that is not exposed to rainwater and left for around 1 month 7) Packaging into plastic and the compost is ready to use.

Based on the observations during the activity, it was seen that the residents were very excited about the socialization. They hope this kind of activity could add to their knowledge and apply it in composting to support their agriculture business in Telang Village. Making compost is done simply with additional material in the form of em4 probiotics, husk, and ash. This activity also becomes an additional knowledge for the residents, especially for farmers and breeders.  Then they can independently make the compost fertilizer. The existence of this compost fertilizer could maintain soil fertility, reduce the use of inorganic fertilizer, and of course saving farming cost.
