Abstract

 AbstrakKatuk (Sauropus androgynus) merupakan tumbuhan herbal yang mengandung protein dan asam lemak yang banyak dimanfaatkan untuk meningkatkan pertumbuhan hewan. Penelitian ini bertujuan untuk menentukan dosis ekstrak daun katuk pada pakan yang dapat meningkatkan pertumbuhan dan survival rate benih ikan bandeng. Benih ikan bandeng yang digunakan berukuran 1,8–1,9 cm dan dipelihara pada akuarium bervolume 15 L dengan padat tebar 15 ekor dalam setiap akuarium. Penelitian ini menggunakan rancangan acak lengkap (RAL) dengan 5 perlakuan dan 3 ulangan. Perlakuan berupa penambahan ekstrak daun katuk pada pakan dengan dosis 0 g/kg (kontrol atau P1), 37,5 g/kg (P2), 75 g/kg (P3), 150 g/kg (P4), dan 300 g/kg (P5) pakan. Penambahan ekstrak daun katuk pada pakan berpengaruh nyata terhadap pertumbuhan mutlak dan Survival Growth Rate (SGR) benih ikan bandeng (P<0,05), dan tidak berpengaruh nyata terhadap survival rate (SR) (P>0,05). Penambahan ekstrak daun katuk sebesar 150 g/kg pakan (P4) menunjukan nilai terbaik pada pertumbuhan mutlak dan SGR benih. Nilai SR tertinggi ditunjukan pada penambahan ekstrak sebesar 300 g/kg pakan (P5) yaitu mencapai 80%. Data pengukuran kualitas air dalam nilai yang baik yaitu suhu 24–30 °C; pH 6–8; salinitas 24–30 ppt; dissolved oxygen (DO) 4,27–5,98 mg/L; dan amoniak 0,07–0,11 mg/L.AbstractKatuk (Sauropus androgynus) is a herbal plant that contains protein and fatty acids which are widely used to increase animal growth. This research aims to determine the dose of katuk leaf extract in feed that can increase the growth and survival rate of milkfish fry. The milkfish seeds used were 1.8–1.9 cm in size and were maintained in 15 L volume aquariums with a stocking density of 15 fish in each aquarium. This research is an experimental study using a completely randomized design (CRD) with 5 treatments and 3 replications. The treatment consisted of adding katuk leaf extract to the feed, namely control P1 0 g/kg, P2 37.5 g/kg, P3 75 g/kg, P4 150 g/kg, and P5 300 g/kg feed. The results of statistical analysis showed that the addition of katuk leaf extract to feed had a significant effect on the absolute growth and Survival Growth Rate (SGR) of milkfish seeds, while the survival rate (SR) showed values that were not significantly different. The addition of katuk leaf extract at 150 g/kg feed (P4) showed the best value for absolute growth and SGR of seeds. The highest SR value was shown when the extract was added at 300 g/kg feed (P5), reaching 80%. The water quality measurement data is in good value, namely a temperature of 24–30 °C; pH 6–8; salinity 24–30 ppt; dissolved oxygen (DO) 4.27–5.98 mg/L; and ammonia 0.07–0.11 mg/L.

Abstract

The availability of high-quality, certified broodstock is a key factor in improving fish farming productivity. However, many small-scale fish farmer groups still rely on uncertified broodstock, leading to reduced fry quality and lower production yields. In response to this issue, a community service program titled Optimization of Certified Broodstock as an Effort to Increase the Productivity of the Rizky Mina Utama Fish Farmers Group in Tarakan City was conducted. The program aimed to enhance the knowledge and technical skills of local fish farmers regarding the selection and management of certified broodstock to improve aquaculture outcomes. The activity was implemented in July 2025 at the Rizky Mina Utama Fish Farmers Group (POKDAKAN) in Karang Harapan Subdistrict, Tarakan City. The implementation team consisted of 25 lecturers and students from Borneo Tarakan University, while the participants included 15 members of the Rizky Mina Utama fish farmers group. The methods used in the program included presentations, hands-on practical training, interactive discussions, and Q&A sessions. The results showed a significant increase in participants’ understanding of broodstock certification, selection techniques, and proper broodstock management. Moreover, the program fostered greater awareness of the importance of using certified broodstock to ensure fry quality and production sustainability. This initiative is expected to support long-term improvements in local aquaculture practices.
