Pertumbuhan Moina sp. (Baird, 1850) yang Dibudidayakan dengan Media Air Limbah Budidaya Lele dan Maggot Hermetia illucens 

Penelitian ini bertujuan untuk mengetahui kandungan nutrien limbah budidaya maggot Hermetia illucens, pengaruh penggunaan air limbah budidaya lele yang diperkaya dengan limbah budidaya maggot Hermetia illucens terhadap pertumbuhan Moina sp., dan dosis limbah budidaya maggot Hermetia illucens yang menghasilkan biomassa Moina sp. tertinggi. Air media berasal dari 25% air limbah budidaya lele ditambah dengan 75% air tawar. Penelitian menggunakan metode Rancangan Acak Lengkap yang terdiri dari empat perlakuan dan tiga ulangan. Perlakuan meliputi pemberian limbah budidaya maggot dengan dosis 0 g/L, 0,75 g/L, 1,5 g/L, dan 2,25 g/L. Moina sp. dibudidayakan selama 13 hari dengan kepadatan awal 20 ind./L dan waktu pemupukan setiap dua hari. Data yang diperoleh dianalisis menggunakan analisis varian dengan tingkat ketelitian 95%. Jika hasil menunjukkan beda nyata maka dilanjutkan dengan Duncan’s Multiple Range Test. Limbah budidaya maggot mengandung Nitrogen (N) 4,68%, Fosfor (P) 0,46%, dan Kalium (K) 1,61%. Kepadatan populasi tertinggi terdapat pada dosis pupuk 1,5 g/L (83,10 ± 3,98 ind/L). Puncak populasi Moina sp. tertinggi terdapat pada perlakuan dosis 2,25 g/L sebanyak 187 ind./L pada hari ke-5. Laju pertumbuhan spesifik Moina sp. tertinggi terdapat pada perlakuan dosis 2,25 g/L 4,627 ± 0,092 ind./L/hari. Biomassa tertinggi Moina sp. pada hari ke-4 terdapat pada dosis 2,25 g/L (18,07 mg/L) dan pada hari ke-8 dan 12 terdapat pada dosis 1,5 g/L (12,17 mg/L dan 3,47 mg/L). Kandungan nutrien Moina sp. tertinggi ditunjukkan oleh dosis 0,75 g/L meliputi kadar protein sebesar 52,92%, lemak sebesar 8,75%, karbohidrat sebesar 39,8%, abu sebesar 5,65%, dan serat kasar sebesar 29,57%.

The Growth of Moina sp. (Baird, 1850) Cultivated Using Catfish Wastewater and Maggot Hermetia illucens Media

This research aims to determine the nutrient content of Hermetia illucens maggot farming waste, to determine the effect of using catfish farming wastewater enriched with Hermetia illucens maggot farming waste on the growth of Moina sp., and to determine the dose of Hermetia illucens maggot farming waste that produces the highest Moina sp. biomass. The air media is composed of 25?tfish aquaculture wastewater and 75% freshwater. The research used a Completely Randomized Design method consisting of four treatments and three replications. The treatments included the administration of maggot farming waste at doses of 0 g/L, 0.75 g/L, 1.5 g/L, and 2.25 g/L. Moina sp. was cultured for 13 days with an initial density of 20 ind./L and fertilization every two days. The data obtained were analyzed using analysis of variance with a 95% confidence level. If the results showed a significant difference, Duncan's Multiple Range Test was then performed. Maggot farming waste contains Nitrogen (N) 4.68%, Phosphorus (P) 0.46%, and Potassium (K) 1.61%. The highest population density was found at a fertilizer dose of 1.5 g/L (83.10 ± 3.98 ind./L). The highest population peak of Moina sp. was found in the 2.25 g/L dose treatment, with 187 ind./L on day 5. The highest specific growth rate of Moina sp. was found in the 2.25 g/L dose treatment, at 4.627 ± 0.092 ind./L/day. The highest biomass of Moina sp. on day 4 was found in the 2.25 g/L dose (18.07 mg/L), and on days 8 and 12, it was found in the 1.5 g/L dose (12.17 mg/L and 3.47 mg/L). The highest nutrient content of Moina sp. was shown by a dose of 0.75 g/L, including a protein content of 52.92%, fat content of 8.75%, carbohydrate content of 39.8%, ash content of 5.65%, and crude fiber content of 29.57%.
