<![CDATA[Abstract: This study aims to determine the effect of feeding fermented vegetable waste of mustard greens and cabbage of use different percentage of feed to growth of catfish (Pangasius sp.) and produce leaflet for class XII biology learning on biotechnology materials. This research was conducted at the Binakrida Street, Simpang Baru Subdistrict, Binawidya District, Pekanbaru City in March-July 2020. The research was conducted in 2 stages, namely: experimental research the effect of feeding fermented vegetable waste of mustard greens and cabbage to growth of catfish and potential analysis stage and leaflet design from experimental research results. The experimental research was designed with a Randomized Block Design consisting of 5 treatments and 3 replications. The feed used is artificial feed containing fermented vegetable waste of mustard greens and cabbage with different percentage of feed, the treatment consists of T1 (15%), T2 (30%), T3( 45%), T4 (60%). The test parameters are the specific growth rate, feed efficiency, survival rate, and water quality. Based on the ANOVA test (analysis of variances), it shows that the feeding fermented vegetable waste of mustard greens and cabbage has a significant effect on the growth of catfish (p <0.05) and T2 treatment produces the best growth with a 2.11% specific growth, 63,36% feed efficiency, 100% survival rate, and water quality that can support the growth of catfish. Based on the analysis of the potential results of experimental research, it can be used as a biology learning leaflet design for biotechnology material in high school.Key Words: Mustard and Cabbage Vegetable Waste Flour, Fermentation, Catfish Growth,Learning Leaflet Design]]>
