Abstrak udang windu merupakan spesies udang indonesia yang mengandung protein tinggi dan memiliki nilai ekspor yang menguntungkan. tujuan penelitian untuk mengetahui pertumbuhan dan dosis terbaik dalam pemberian tepung cangkang kerang hijau pada pakan udang windu. penelitian ini dilakukan di laboratorium pembenihan dan pembiakan ikan fakultas kelautan dan perikanan universitas syiah kuala. pencetakan pakan dilakukan di desa tibang, kecamatan syiah kuala, kota banda aceh. menggunakan metode rancangan acak lengkap dengan 4 perlakuan dan 3 kali ulangan. parameter penelitian meliputi pertumbuhan berat mutlak, pertumbuhan panjang mutlak, laju pertumbuhan spesifik, rasio konversi pakan, kelangsungan hidup dan kualitas air. hasil penelitian menunjukkan perlakuan terbaik pada perlakuan d dengan penambahan tepung cangkang kerang hijau sebanyak 3%, sehingga nilai pertambahan panjang mutlak sebesar (2,99 cm), berat mutlak (0,39), laju pertumbuhan spesifik (19,88%), ratio konversi pakan (1,19), efisiensi pakan (84,14%) dan kelangsungan hidup (98%). penambahan tepung cangkang kerang hijau pada pakan berpengaruh terhadap pertumbuhan udang windu.

ABSTRACT Tiger prawn is an Indonesian shrimp species that contains high protein and has a profitable export value. The aim of the study was to determine the growth of tiger prawns that had been given green mussel shell meal and to find out the best dose of green mussel shell powder for the growth of tiger prawns. This research was conducted at the Fish Hatchery and Breeding Laboratory, Faculty of Maritime Affairs and Fisheries, Syiah Kuala University. Feed molding was carried out in Tibang Village, Syiah Kuala District, Banda Aceh City. Using a completely randomized design with 4 treatments and 3 replications. The research parameters included absolute weight growth, absolute length growth, specific growth rate, feed conversion ratio, survival and water quality. The results showed that the best treatment was in treatment D with the addition of green mussel shell flour as much as 3%, so that the absolute length gain value was (2.99 cm), absolute weight (0.39), Specific Growth Rate (19.88%), Feed Conversion Ratio (1.19), Feed Efficiency (84.14%) and Survival (98%). The addition of green mussel shell powder to the feed has an effect on the growth of tiger prawns.
