Abstract

The probiotic innovation training programme based on market waste implemented at the Krido Yuwono Mina Padi Technopark Group aims to increase tilapia productivity and farming efficiency through the use of organic waste as raw material for probiotics. This training involves participants in the production of probiotics through the fermentation of market waste using lactic acid bacteria starters. The evaluation results show an increase in tilapia productivity of around 15-20% with better feed efficiency and a reduction in ammonia levels in pond water, which was previously a major problem in maintaining fish health. The community involved in this programme also increased their confidence in managing tilapia farming efficiently and received new knowledge that can reduce operational costs. This programme has achieved significant social and economic impacts and is expected to develop into a sustainable community empowerment model in the field of aquaculture and support more environmentally friendly waste management.

Abstract

Guppy fish is one type of ornamental fish which is in great demand due to its interesting color variations. Color of ornamental fish will be brighter if the feed contains color pigments. The study aims to determine the effect of Astaxanthin supplement in pellets on the color brightness of guppies and to find the best dose of Astaxanthin supplement in pellets on the color brightness of guppies. The method used in the study was complete randomized design (CRD) consisting of five treatments (Astaxanthin supplements of 0%, 2%, 3%, 4% and 5%) and three replications. The experimental fish were male guppy fish Strain HB Red ± 3 cm length with a density of 3 fish/aquarium. Feeding was done twice a day and siphoning was done every afternoon. The parameters observed were Chroma value, survival rate and water quality. The results show that the supplement of Astaxanthin in pellets successfully increase the brightness of guppies and the best dose of Astaxanthin supplement in pellets was 5% with an increase in Chroma value of 4.82%. The survival rate obtained was 100%. Water quality includes an average temperature of 26-27 ℃ and pH of 6-7 and dissolved oxygen (DO) was 6.95-7.93 ppm

Abstract

Amylolytic bacteria in the digestive tract of tilapia are bacteria that produceamylase enzymes, which function to break down carbohydrates, thereby aidingthe digestive process. The presence of amylolytic bacteria is influenced by feedand the environment. The purpose of this study was to determine the proportionand activity index of amylolytic bacteria in the intestines of tilapia. This studyused an observational method with purposive sampling. Amylolytic bacteriawere isolated from the intestines of tilapia in Rice fish farming Blocks A and E.The successfully isolated bacteria were grown on 1% starch agar medium withan incubation time of 48 hours and observed at 24-hour intervals. Then, severalcharacteristic tests were carried out, including Gram staining, KOH, catalase,and oxidase tests. Based on the results of the study, the proportion of amylolyticbacteria was found in 10 isolates with a proportion of 44% and 12 isolates witha proportion of 48% in the intestines of tilapia from the two blocks. The averageamylolytic activity index obtained from block A was 0.96 ± 0.237, and fromblock E was 1.49 ± 0.501. The largest amylolytic activity index was obtainedin isolate KSA 19 with a value of 1.33 from block A, while from block E, thelargest amylolytic activity index value was 2.6 in isolate KSE 5.
