Abstract

This research aimed to determine the nutrient content and total bacteria in bio-slurry. In addition, the abundance of plankton, total bacteria and protein content of milkfish cultivated in ponds using bio-slurry were analyzed. The first stage was to make bio-slurry by testing two different main raw materials; cattle manure and chicken manure. They were made in separate containers to compare the nutrients produced. The chopped leaves, rice water stool, probiotics, and molasses were mixed in tank fermentation. After 3 weeks, the bio-slurry was harvested and analyzed for its nitrogen, phosphorus, and potassium (NPK), as well as its bacterial content. Then, the application of a combination of bio-slurry was carried out in traditional ponds. The results showed that the bio-slurry treated with chicken manure contained significantly higher NPK (390±56.57; 2,332.5±1,438.96; 905.5±656.90 pmhos/cm) than the treatment with cattle manure (76.5±4.95; 647.5± 81.32; 264.5±32.53 pmhos/cm). Then, the average data of total bacteria show that bio-slurry from chicken manure had significantly higher numbers (15±4.24 MPN/mL), while for total Escherichia coli bacteria was lower (8.6±0.57x103 cfu/mL) than those from cattle manure (29.5±6.36 MPN/mL; 2.45±0.21x105 cfu/mL). After applying to the pond, the abundance and diversity of plankton were monitored. The data showed that organic waste can be presumed to establish a more favorable conditions for the growth of plankton characterized by high nutrient content and less content of pathogenic bacteria. This indicated that animal manure can be utilized in milkfish cultivation because it contains sufficient nutrients and is safe to be used in aquaculture.
