The high prevalence rate of stunting in West Sulawesi Province, which reached 33.8, places West Sulawesi in second place in the province with the highest stunting in Indonesia. One effort to prevent stunting is to diversify the intake of complementary foods for children aged 6-23 months by utilizing local natural resources. This research aims to formulate flying fish, barley flour, and Moringa leaves as a functional food in processed nuggets as a menu for Supplementary Feeding (PMT) for babies under two years old. The research method was carried out in three stages, namely, the nugget formulation in two formulas, namely F1 and F2. Next, an organoleptic test is carried out to select the best formula, followed by a nutritional content analysis, which includes proximate analysis and mineral testing. The research results showed that the nugget formula selected was based on organoleptic tests on 30 panelists, namely F1 nuggets with a mixture of 175 g of flying fish, 75 g of barley flour, and 10 g of moringa leaves. These nuggets contain nutrients per 100 grams, namely protein 14.36 g, carbohydrates 27.83 g, fat 5.53 g, crude fiber 1.22 g, iron 62.78 mg/kg, calcium 97.53 mg/kg, and zinc 15.52 mg/kg. Therefore, nuggets with the selected formula are rich in the nutrients needed in complementary breast milk foods to prevent stunting.

The slurry is one of the results of fermentation of organic material from a biogas reactor, which can be used as plant fertilizer because it is rich in macronutrients. The Brazilian spinach plant, known to contain a lot of vitamin E, is suitable for organic cultivation in a hydroponic system, which requires good fertilizer intake. This research aims to study the effect and best dose of liquid organic fertilizer from human waste-based biogas reactor leachate on the growth of Brazilian spinach (Alternanthera sissoo hort) in a hydroponic system. Six treatments were used in this study: K0 (no fertiliser), K1 (500 ppm fertiliser from AB mix), K2 (500 ppm commercial POC), P1 (250 ppm biogas reactor slurry POC), and P2 (500 ppm biogas) with 5 replications for each treatment. Brazilian spinach growth parameters measured included plant height, number of leaves, root length, wet weight, and dry weight. Plant growth parameter data were analyzed statistically using ANOVA and DMRT tests. The nutrient analysis results show that the POC macronutrient levels of human feces slurry does not meet the POC standards, according to the Ministry of Agriculture. However, giving it at a dose of 250 ppm has been proven to support the growth of Brazilian spinach plants.

Many aquaculture wastes are suspended in the water column in that the presence of clams as filter feeders is required to utilize the waste for growth. In this study, blood clams from four aquaculture systems were evaluated to determine their growth, namely monoculture systems, polycultures, Integrated Multi Trophic Aquaculture (IMTA) non-paddy cocultures, and IMTA with paddy cocultures. Blood clams, tilapia, and tiger shrimp are stocked at as much as 20 each in 90 L of brackish water, whereas the density of sea cucumbers is 10 individuals. For paddy, reared using a floating method that uses trays. For four weeks, feed was given four times a day as much as 10% of the biomass. The results showed that the aquaculture system were a significant effect (P<0.05) on Spesific Growth Rate (SGR). The SGR of blood clams when combined with the IMTA systems were significantly higher (P<0.05) than that of the monoculture and polyculture systems. In contrast to growth, morphometric characteristics were not significantly affected (P>0.05) by aquaculture system. Apart from studies in laboratory scale, the highest growth of blood clams is obtained if cultured with complete trophic levels through the IMTA paddy system.
