QUALITY IMPROVEMENT OF FEED CHEMICAL COMPOSITION WITH THE ADDITION OF DRAGON FRUIT SKIN FLOUR (Hylocereus polyrhizus)

Providing high-quality feed is one of the efforts to increase fish productivity and growth reduce mortality. One additional alternative ingredients as a source vegetable protein dragon fruit peel which can be used an ingredient in feed. The study chemical composition with addition flour essential information determine effect benefits by-products (waste) from food processing aquaculture development. This aims evaluate quality after being treated through proximate analysis. test was carried out at Agricultural Product Technology Laboratory Lampung State Polytechnic, June August 2020. results showed that had carbohydrate content 50.74%, crude fiber 26.22%, ash 21.35%, 5.08%, fat 4.80% (dry weight). increased feed, added flour. highest treatment 1.5%, namely 37.79% weight), decreased by 2.0%. 2.0% 11.32% fiber, carbohydrates has increasing dose substitute manufacture also increases utilization waste, especially aquaculture, waste disposal into environment.
