Ikan komet (Carassius auratus) adalah salah satu jenis ikan air tawar yang banyak digemari di kalangan masyarakat khususnya bagi pencinta ikan hias. Ikan komet memiliki warna yang indah serta bentuk dan gerakan yang menarik. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian molase dan dosis yang optimal terhadap pertumbuhan dan tingkat kelangsungan hidup benih ikan komet (Carassius auratus). Penelitian ini dilaksanakan pada bulan Juli 2022 – Agustus 2022 di Unit Pelaksanaan Teknis Daerah Balai Benih Ikan (BBI) Lukup Badak, Takengon, Aceh Tengah. Penelitian ini menggunakan metode eksperimental dengan Rancangan Acak Lengkap (RAL), yang terdiri dari 4 perlakuan dan 3 ulangan. Perlakuan A berupa perlakuan kontrol (pakan komersil 50 gram, tanpa molase), perlakuan B (pakan komersil 50 gram + molase 5%), perlakuan C (pakan komersil 50 gram + molase 7 %), perlakuan D (pakan komersil 50 gram + molase 9 %). Hasil analysis of variance (ANOVA) pada penelitian ini menunjukkan pemberian molase berpengaruh nyata (P0,05) terhadap rasio konversi pakan, efisiensi pakan dan tingkat kelangsungan hidup. Hasil uji lanjut menunjukkan nilai pertumbuhan panjang mutlak tertinggi terdapat pada perlakuan D yaitu senilai 1,48 cm, nilai pertumbuhan berat mutlak tertinggi terdapat pada perlakuan C dan D yaitu senilai 2,15 g dan 2,01 g serta nilai laju pertumbuhan spesifik tertinggi terdapat pada perlakuan C dan D yaitu senilai 1,56 %/hari dan 1,75 %/hari.

Comet fish (Gilded Carassius) is a type of freshwater fish that is much-loved among the public, especially for lovers of ornamental fish. Comet fish have beautiful colors and interesting shapes and movements. This study aims to determine the effect of giving molasses and the optimal dose on the growth and survival rate of comet fish fry (Gilded Carassius). This research was carried out in July 2022 – August 2022 at the Regional Technical Implementation Unit of the Lukup Badak Fish Seed Center (BBI), Takengon, Central Aceh. This study used an experimental method with a completely randomized design (CRD), which consisted of 4 treatments and 3 replications. Treatment A was a control treatment (50 gram commercial feed, without molasses), B treatment (50 gram commercial feed + 5% molasses), C treatment (50 gram commercial feed + 7% molasses), D treatment (50 gram commercial feed + molasses 9 %). The results of the analysis of variance (ANOVA) in this study showed that giving molasses had a significant effect (P0.05) on feed conversion ratio, feed efficiency and survival rate. Further test results showed that the highest absolute length growth value was in treatment D, which was 1.48 cm, the highest absolute weight growth value was in C and D treatments, which were (2.15 g and 2.01 g) and the highest specific growth rate was in treatment C and D which is equivalent to (1.56%/day and 1.75%/day) Keywords : comet fish, molasses, survival, growth.
