Giant mudskippers (Periophthalmodon schlosseri) are amphibious fish and considered as endemic fish, so it can not be found in any other place and they live in a typical habitat in a tidal area with the mud of mangroves. Mudskipper These fish is relatively untapped as food source. This research aims to obtain the optimum conditions of enzyme concentration, pH, temperature, and hydrolysis incubation time on the degress of hydrolysis of alcalase enzyme in giant mudskipper (P. schlosseri). The production of fish protein hydrolysate was conducted by varying one parameter at a time to determine its effect without considering interactions with other parameters. The results obtained optimum hydrolysis at 1.5% alcalase concentration of protein weight, pH 7.5, temperature 50°C, and the duration of hydrolysis 2 hours. The degree of hydrolysis produced at the optimum condition was 67.44%.
