Penelitian ini bertujuan untuk mengetahui pengaruh pemberian pakan daun talas terhadap pertumbuhan gurami (Osphronemus goramy Lac. 1801) pada tahap pembesaran segmen III dan untuk mengetahui dosis pakan yang memberikan pertumbuhan tertinggi terhadap gurami (O. goramy Lac. 1801) pada tahap pembesaran segmen III. Rancangan penelitian menggunakan model Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 3 ulangan. Perlakuan yang diberikan adalah pakan pelet 100%, pakan pelet 75% + daun talas 25%, pakan pelet 50% + daun talas 50%, pakan pelet 25% + daun talas 75%. Ikan gurami yang digunakan dalam penelitian ini berukuran ±350 g. Ikan gurami dipelihara selama 111 hari yang diberi pakan sebanyak 2% dari berat total biomassa gurami. Data sintasan, pertumbuhan mutlak berbasis berat dan panjang, laju pertumbuhan spesifik berbasis berat dan panjang, koefisien pertumbuhan termal dan rasio efisiensi protein dianalisis secara statistik menggunakan analisis sidik ragam atau Analysis of Variance dengan tingkat kepercayaan 95 %. Apabila terdapat hasil beda nyata antar perlakuan dilanjutkan dengan Duncan Multiple Range Test. Hasil penelitian menunjukkan bahwa pemberian pakan dengan dosis pelet 50% + daun talas 50% memberikan pengaruh beda nyata terhadap pertumbuhan mutlak berbasis berat dan panjang, laju pertumbuhan spesifik berbasis panjang, dan rasio efisiensi protein pakan, namun tidak memberikan pengaruh nyata terhadap sintasan, laju pertumbuhan spesifik berbasis berat dan koefisien pertumbuhan termal. Pemberian dosis pakan pelet 50% + daun talas 50% memberikan nilai pertumbuhan tertinggi pada pembesaran ikan gurami segmen III.

This study aims to determine the effect of taro leaves feed on the growth of giant gourami (Osphronemus goramy Lac. 1801) at the growthout segment stage III and to determine the dose of feed that gave the highest growth to giant gourami (O. goramy Lac. 1801) at the rearing segment stage III. The research design used a Completely Randomized Design (CRD) model with 4 treatments and 3 replications. The treatments given were 100% commercial feed, 75% commercial feed and 25% taro leaves, 50% commercial feed and 50% taro leaves, 25% commercial feed and 75% taro leaves. The giant gourami used in this study was ±350 g. The giant gourami fish were reared for 111 days which were fed as much as 2% of the total weight of the giant gouramy biomass. Data on survival rate, absolute growth based on weight and length, specific growth rate based on weight and length, thermal growth coefficient and protein efficiency ratio were statistically analyzed using analysis of variance with a 95% confidence level. If there were significant differences between treatments, then proceed with the DMRT test (Duncan's Multiple Range Test). The results showed that feeding with a dose of 50% pellet + 50% taro leaves had a significant effect on the growth of absolute weight, absolute length, specific length, and feed protein efficiency ratio, but did not had a significant effect on the growth of specific weight, thermal growth coefficient, and survival rate. Giving a dose of 50% pellet + 50% taro leaves gave the highest growth value at the rearing segment stage III of giant gouramy.
