Fish feed is one of effective way to minimize production costs in fish farming. Coconut pulp contains 13,09% protein so that it can be used as an alternative raw material for fish feed. Flour "Duckweed"(Lemna minor) is one of natural protein source as a mixed materials that contains 15-40% protein. The purpose of this study was to know the quality of fish feed with the raw materials from coconut pulp flour with "Duckweed" (Lemna minor) flour. This research method using Completely Randomized Design (RAL) with two factors. The first factor is the weight of the coconut pulp flour (30 g, 40 g and 50 g) and the second factor is the weight of the "Duckweed" (Lemna minor) flour (25 g and 30 g) with 2 repetitions. The results showed that the best quality of fish feed on treatment of coconut pulp flour with a weight of 30 gr, while addition of “Duckweed” (Lemna minor) flour has no effect on the protein content of the fish feed.
