ABSTRAK

Cacing sutra (Tubifex sp.) salah satu pakan alami ikan memiliki kandungan nutrisi cukup baik. Media yang dipakai biasanya adalah lumpur, limbah sayur dan pupuk kotoran ayam. Tujuan penelitian untuk mengetahui perbedaan persentase limbah sayur terhadap populasi. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan lima perlakuan dan tiga kali ulangan yaitu Pelakuan A (50% lumpur + 0% limbah sayur + 50% pupuk kotoran ayam), Perlakuan B (50% lumpur + 12,5% limbah sayur + 37,5% pupuk kotoran ayam), Perlakuan C (50% lumpur + 25% limbah sayur + 25% pupuk kotoran ayam), Perlakuan D (50% lumpur + 37,5% limbah sayur + 12,5% pupuk kotoran ayam) dan Perlakuan E (50% lumpur + 50% limbah sayur + 0% pupuk kotoran ayam). Hasil penelitian ini menunjukkan bahwa pada hari ke-40 perlakuan A memiliki pertumbuhan populasi relatif tertinggi sebesar 245,73%. Hasil uji ANOVA menunjukkan bahwa pada hari ke-40 berbeda nyata terhadap populasi sehingga H0 ditolak dan H1 diterima. Kualitas air pada peneitian ini masih termasuk dalam batas toleransi yaitu suhu (26,1-27,6°C), DO (4,29-5,5 mg/L), pH (6,04-7,35) dan amoniak (0,25-3,66 mg/L).

ABSTRACT

Silk worms (Tubifex sp.) are a natural fish food that has quite good nutritional content. The media used are usually mud, vegetable waste and chicken manure. The aim of the research was to determine the difference in the percentage of fermented vegetable waste in the population. This research used a Completely Randomized Design (CRD) with five treatments and three replications, namely Treatment A (50% mud+0% vegetable waste+50% chicken manure), Treatment B (50% mud + 12.5% ??vegetable waste + 37.5% chicken manure). Treatment C (50% mud+ 25% vegetable waste+ 25% chicken manure). Treatment D (50% mud 37.5% vegetable waste + 12.5% ??chicken manure fertilizer) and Treatment E (50% mud 50% vegetable waste + 0% chicken manure fertilizer). The results of this study showed that on the 40^th day treatment A had the highest relative population growth of 245,73%. The result of the ANOVA test showed that on the 40^th day there was a significant difference in the population so that H0 was rejected and H1 was accepted. The water quality in this study was still within the tolerance limits , namely temperature (26,1-27,6°C), DO (4,29-5,5 mg/L), pH (6,04-7,35) dan amoniak (0,25-3,66 mg/L).
