Abstract

This study aims to analyze the effect of media composition and dose on the growth of silkworms. The test animals used in this study were silkworms (Tubifex sp.). The method used in this study was an experimental method using a completely randomized design (CRD) consisting of 5 treatments and 3 replications in order to obtain 15 experimental units, namely P1 (50% fermented chicken manure, 25% fermented tofu dregs and 25% tapioca meal), P2 (50% sludge, 25% fermented tofu dregs and 25% tapioca meal), P3 (50% fermented chicken manure, 25% fermented tofu dregs and 25% fermented bran), P4 (50% mud, 25% tofu dregs fermented and 25% Fermented Bran), P5 (25% fermented chicken manure, 25% mud, 25% fermented tofu dregs, 25% Fermented Bran). The results showed that there was no effect between treatments on absolute growth and productivity but the use of substrates in silkworm cultivation for 30 days with a composition of 25% fermented chicken manure, 25% mud, 25% fermented tofu dregs and 25% fermented bran could increase absolute growth. silk worms amounted to 7.2 g and a productivity value of 0.76 g / cm2.

Abstract

Eel seeds for aquaculture are primarily sourced from the wild. These seeds respond poorly to feed during the initial rearing phase. Therefore, this study aimed to provide feed that eels can consume in the early stages of culture. This study used an experimental method by testing the level of eel acceptance for natural feed, namely worms (Lumbricus sp.), golden snails (Pomacea sp.), chicken intestines, and maggots (black soldier flies), which will then be used as attractants mixed with pellet flour. Based on the order of feed selection and the time duration of eel response to the feed, eels preferred earthworms and snails as feed compared to maggots and chicken intestines. However, the four tested feed types can be consumed by eels. Mixing earthworms with pellet meal in the form of paste feed was responded well by eels. Eels consumed more (p <0.05) pellet meal mixed with earthworms than feed that did not have earthworms added to it. The incorporation of earthworms as an attractant in paste feed, as much as 50%, produced the same eel growth (P> 0.05) as eels given 100% worms. It indicated that a combination of artificial feed and earthworms could facilitate the consumption of artificial feed by eels in the initial phases of culture.
