New Knowledge

Integrated aquaculture management systems, aquaculture, and crop cultivation can be implemented in synergy where each business that supports each other, supports each other, support each other, by optimally utilizing the potential resources needed. Sapen Village, Mojoaban District, Sukoharjo Regency chose the location of empowerment because it has the potential for integrated farming. Livestock waste that is diverted and converted into pollution sources, on the other hand, the fishery business is very dependent on pellet feed, it is agreed that integration will occur, so the problem of livestock waste can be solved by presenting natural food sources for the fishing business. The program carried out is the socialization of alternative animal feed selection and the socialization of how to make alternative feed. The selection of alternative fish feed, besides being able to incur fish farmers' production costs, is also a form of integration between cattle and goat groups and fish livestock groups. From the implementation of this community service program, it will gain new knowledge about the management of agricultural waste by developing earthworm (lumbricus rubelius) cultivation as fish feed ingredients. Besides, the public also gained new knowledge about how to process livestock as an alternative to fish food.Keyword: integrated farming systems, livestock waste breeding, alternative fish feed

Regional Partnership

Zero waste agriculture is an agricultural concept oriented around the decomposition cycle of organic materials which integrates agricultural and livestock systems to reprocess waste material. Agricultural waste is used as animal feed while livestock waste/excrement is reprocessed into organic fertilizers. The Regional Partnership Service Program (PKW) aims to assist farmers in developing integrated farming businesses based around zero waste agriculture. PKW was held between May and July 2021 in Tindaki Village, South Parigi District, Parigi Moutong Regency. The implementation of this regional partnership program was carried out through a Participatory Action Programs approach, where partners are directly involved in the adoption and application of the various skills that had been developed. The procedure for activity implementation was carried out through several stages, namely: (a) counseling on zero waste agriculture, (b) training in and application of zero waste agriculture technology in the form of demonstration plots for the application of technological products, (c) coaching and mentoring, and (d) the utilization stage of technology product. The findings from the implementation concluded that the agricultural development training based on zero waste agriculture was a success, and the technology had been adopted by the community, marked by the ability to make and develop compost and liquid organic bio-urine fertilizers. Both types of organic fertilizers had been applied in the demonstration plots to assess their effectiveness in reducing the use of inorganic fertilizers. Rice production is equivalent to 5.6 tons/ha and 6 tons/ha in conventional land. These results show potential benefits for farmers, particularly regarding lower production costs compared to the usage of conventional land. Zero waste agriculture is a method of farming and livestock raising that utilizes their waste products for energy production.

Integrated farming system is a system that emphasized linkages and synergism of farming units waste utilization. The objective of this study was to analyze  the economic farming activity of Rice Livestock Integrated Farming System (RLIFS) and non RLIFS farmers. The results showed the usage allocation of family and external labor to RLIFS farmers was relatively greater than non RLIFS farmers. The RLIFS farmers’ income of rice farming, other crops and non-agricultural was relatively larger than non RLIFS  farmers, while non RLIFS farmers had greater income from livestock (cow and non cow) business and farm labor. The production costs of rice farming and livestock business were still greater in RLIFS farmers although they used manure produced by their own and also provide straw of rice production as animal feed. This was due to several factors (1) The proportion of the cost of using manure was very small in the cost of rice farming if the use of manure only a supporting fertilizer and not the main fertilizer for plant. (2) Some farmers were still buying and using anorganic or chemical fertilizers because of their mindset who wanted fast and instantaneous ones. Some farmers also felt that manure contained less nutrients so they used it in small quantities. The household income total of RLIFS farmers was higher than non RLIFS farmers.

Scarcity of fertilizer is always a problem at the farm level because the level of dependence of farmers on fertilizer needs is very high. The need for fertilizer at the farmer level continues to increase over the years, this raises the problem of environmental pollution and also a decrease in soil quality. In addition, farmers' income is relatively low due to several factors, namely high production costs and low production, on the other hand, due to the limited land area. One solution to address this problem is through the integration of Crops and livestock systems. The purpose of this activity is to provide knowledge, training and assistance to farmers in maximizing the potential of agricultural livestock waste as compost in crop and livestock integration systems. The method of activity is carried out by field observations about the problems faced by farmers. The results of the activity can be concluded that partner farmers are able to utilize feces waste and animal feed into compost as a source of nutrition for plants, in a day farmers can produce 2.5 kg of compost from animal manure and feed from 2 goats so that in a year farmers can produce 912.5 kg of compost. In addition, partner farmers are also able to utilize the technology model of crop cohesiveness in maximizing the potential of land in conditions of limited land area. Previously, farmers only used one type of farming business, with this activity farmers could work on two or more types of farming in one land, so farmers could increase their income.   Keywords: Integration, organic fertilizer, fertility, economy.   ABSTRAK Kelangkaan pupuk selalu menjadi persoalan di tingkat petani karena tingkat ketergantungan petani akan kebutuhan pupuk sangatlah tinggi.

Operation and effluent treatment costs are limiting factors for the success of recirculating aquaculture systems (RAS) in meeting seafood demand in the United States. Adopting a capture-and-reuse waste management model similar to terrestrial agriculture farmers would allow RAS farmers to monetize effluent and offset production costs. The moisture content and nutrient profile of RAS effluent makes it a potential option for use as a hydroponic fertilizer. Treatment of RAS waste is needed to mineralize particulate-bound nutrients before becoming a viable hydroponic nutrient solution. Anaerobic treatment (AT), a method used by municipal and agricultural waste treatment facilities to reduce total solids, has been shown to successfully mineralize particulate-bound nutrients from RAS effluent. Continuously mixed anaerobic batch bioreactors were used to evaluate the degree to which AT may mineralize particulate-bound nutrients in solid RAS waste. Concentrations of twelve different macro- and micro-nutrients were analyzed in the waste before and after treatment. Effluent samples were analyzed to determine the fraction of each nutrient in the solid and aqueous forms. This study showed that AT is an effective method to mineralize particulate-bound nutrients in RAS effluent and the mineralization rate data may be used to design a pilot-scaled flow-through RAS effluent treatment system.
