Abstract

Penelitian ini bertujuan untuk menganalisa pengaruh komposisi dan dosis media terhadap pertumbuhan cacing sutera. Hewan uji yang digunakan dalam penelitian ini yaitu Cacing Sutra (Tubifex sp.). Metode yang digunakan dalam penelitian ini adalah metode eksperimental menggunakan Rancangan Acak Lengkap (RAL) yang terdiri dari 5 perlakuan dan 3 kali ulangan sehingga diperoleh 15 unit percobaan,yakni P1 (50% kotoran ayam terfermentasi, 25% ampas tahu terfermentasi dan 25% tepung tapioka), P2 (50%  Lumpur, 25% ampas tahu terfermentasi dan 25%  Tepung tapioka), P3 (50% kotoran ayam terfermentasi, 25% ampas tahu terfermentasi dan 25% Dedak Terfermentasi), P4 (50%  Lumpur, 25% ampas tahu terfermentasi dan 25%  Dedak Terfermentasi), P5 (25% kotoran ayam terfermentasi, 25% Lumpur, 25% ampas tahu terfermentasi, 25%  Dedak Terfermentasi). Hasil penelitian menunjukkan bahwa tidak adanya pengaruh antar perlakuan pada pertumbuhan mutlak dan produktivitas tetapi  penggunaan susbstrat pada budidaya cacing sutra selama 30 hari dengan komposisi kotoran ayam terfermentasi 25%, Lumpur 25%, Ampas tahu terfermentasi 25% dan Dedak terfermentasi 25% dapat meningkatkan pertumbuhan mutlak cacing sutra sebesar  7,2 g dan nilai produktivitas 0,76 g/cm2.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.
