Abstract

In increasing fish farming production, it is very dependent on the availability of fish feed which has recently been expensive. To overcome this, was necessary to find alternative feeds that have nutritional value according to the needs of cultivated organisms. Maggot (Hermetia illucens Linn.) is a black soldier fly larvae that has a chewy texture, high protein and has the ability to secrete natural enzymes that help improve the digestive system of fish. . The aimed of this research was to find out the amount of maggot (H. illucens Linn.) production in several cultivation media with different treatments. The  results of the study found that it took up to 2 weeks to produce maggot that had ready to be used as feed. Maggot had the potential to be cultivated as an alternative to fish feed.

Abstract

The goal of this research was to observe the effects of yeast on the density rate of Alona sp. with various concentrations compared to the density rate in horse manure media. The treatments are as follows, treatment A yeast 30 mg yeast/0.5 L water, treatment B yeast 10 mg yeast/0.5 L water, treatment C yeast 5 mg yeast/0.5 L water, treatment D yeast 1 mg yeast/0.5 L water, treatment E 0.5 L well water, treatment F horse manure media (horse manure 10 gr, soil 50 g in 0.5 L water). The research was carried out for two weeks, and the density calculation was done once a week. The results obtained based on Anova One Way analysis are that yeast with different concentrations does not have a significant effect on the density of Alona sp. Nevertheless, it was concluded that the giving of yeast to Alona sp. is much more efficient and effective compared to horse manure media, because it is more hygienic, easy to obtain and not expensive, also from nutritional value, yeast has a higher value compared to horse manure media. The measuring of water quality parameter during the research was temperature around 26-30°C.

Abstract

This community service activity aimed to apply the bioflock culture techniques and good business management to fish farmer group. As much as 2000 individuals catfish ranging from 5-7 cm in length was used in this activity. The fish obtained from Fresh Water Aquaculture Board, Tatelu were pun in oxygenated plastic bags and transported to fish farmer group in West Kombos, District of Singkil. The culture activity that applied the bioflock culture techniques took place for about six months. The specific target to be achieved at the end of the training were all members of the partner group could make the fish feed formulations with local raw materials by themselves. In addition, they have skilled on management, marketing and could have simple bookkeeping note as well.  In overcoming these problems, an approach was carried out through direct field counseling and training.  Then, partners had the opportunity to practice it until they can do it by themselves. The first step of this activities was preparation, the second was three days of training (4 hours /day), and the last were monitoring, evaluation, and assistance up to the end of this program
