(Lisya Junus. 26020119130037. Subtitusi Tepung Maggot (Hermetia illucens) dalam Pakan Terhadap Performa Pertumbuhan dan Tingkat Kelangsungan Hidup Benih Ikan Mas Koki (Carassius auratus). Vivi Endar Herawati dan Desrina)
Studi dilakukan untuk mengetahui dan membandingkan pengaruh antara tepung maggot dalam pakan uji dengan pakan komersial terhadap performa pertumbuhan dan kelangsungkan hidup mas koki (Carassius auratus) telah dilakukan selama 30 hari. Penelitian ini menggunakan metode eksperimental, rancangan acak lengkap (RAL), meliputi 4 perlakuan 3 kali ulangan. Adapun perlakuan dalam penelitian ini, antara lain A sebagai kontrol (pakan komersial), pakan uji B, C, dan D yang masing-masing memiliki level subtitusi tepung maggot (g/kg pakan uji) secara berurutan 150, 175, dan 200 pakan. Ikan uji dalam penelitian ini, yaitu ikan mas koki yang memiliki bobot awal rata-rata 3,2 ± 1,38 gram per ekor dengan padat tebar 8 ekor/100 liter. Wadah pemeliharaan ikan mas koki dalam penelitian ini menggunakan akuarium dengan ketinggian air 50 cm. Data performa pertumbuhan yang diambil meliputi laju pertumbuhan spesifik (SGR), total konsumsi pakan (TKP), rasio konversi pakan (FCR), efisiensi pemanfaatan pakan (EPP), dan kelulushidupan (SR). Hasil penelitian menunjukkan bahwa subtitusi tepung maggot dalam pakan berpengaruh nyata (P<0,05) terhadap SGR, TKP, FCR, dan EPP, tetapi tidak berpengaruh terhadap kelulushidupan. Berdasarkan hasil penelitian, perlakuan terbaik diperoleh pada perlakuan kontrol menggunakan pakan komersial yang menghasilkan SGR (0,84%/hari), EPP (30,46%), FCR (2,87), TKP (29,01 gram), dan SR (86,67%). Sementara itu, dosis subtitusi tepung maggot terbaik yang memiliki hasil mendekati perlakuan kontrol adalah 175 g/kg yang mampu menghasilkan SGR (0,55 %/hari), EPP (21,90%), FCR (3,44), TKP (26,67 gram), dan SR (80%).

ABSTRACT
(Lisya Junus. 26020119130037. Substitution of Maggot (Hermetia illucens) Meal in Feed on Growth Performance and Survival Rate of Goldfish Fry (Carassius auratus). Vivi Endar Herawati and Desrina)
The study was conducted to determine and compare the effect of maggot meal in the test diet with commercial feed on the growth performance and survival of chef carp (Carassius auratus) has been conducted for 30 days. This study used an experimental method, complete randomized design (CRD), including 4 treatments with 3 replicates. The treatments in this study, including A as a control (commercial feed), test feed B, C, and D, each of which has a substitution level of maggot meal (g/kg test feed) sequentially 150, 175, and 200 feed. The experimental fish in this study, namely goldfish, had an average initial weight of 3,2 ± 1,38 gram per fish with a stocking density of 8 fish/100 liters. The maintenance container for the goldfish in this study used an aquarium with a water level of 50 cm. Growth performance data taken included specific growth rate (SGR), total feed consumption (TFC), feed conversion ratio (FCR), feed utilization efficiency (FUE), and survival rate (SR). The results showed that the substitution of maggot flour in feed had a significant effect (P<0.05) on SGR, TFC, FCR, and FUE, but had no effect on survival rate. Based on the results, the best treatment was obtained in the control treatment using commercial feed which resulted in SGR (0.84%/day), EPP (30.46%), FCR (2.87), TKP (29.01 grams), and SR (86.67%). Meanwhile, the best substitution dose of maggot flour that has results close to the control treatment is 175 g/kg which is able to produce SGR (0.55%/day), EPP (21.90%), FCR (3.44), TKP (26.67 grams), and SR (80%).
