The purpose of this research is to 1. To review the utilization of fish wastes leubim black to economic value products in the form of gelatine and to learn the process of making gelatine on bones and fish skin black leubim by using different concentrations of NaOH. The research was conducted using a complete Randomized factorial design, which consists of two factors. The first factor is the type of raw materials (L) consisting of 2 levels, L1= fish bone leubim, L2= fish skin leubim. The second factor was the concentration of NaOH (K), which consists of 3 levels i.e. K1= without soaking NaOH, K2 = 0.4% and K3 = 0.8%. combination treatment is 2 × 3 = 6, using 2 times repeats so retrieved 12 units of the experiment. Analysis of the test parameters that do consist of protein, levels of ash, moisture content, pH value, viscosity and descriptive color and smell. Kinds of raw materials very real effect (P > 0.01) to yield, moisture and ash content of gelatin is produced. The concentration of NaOH very real effect (P > 0.01) terehadap yield, moisture content, ash content, drajat acidity (pH), and viscosity of gelatin is produced. While the second interaction effect very real treatment (p. 0.01) to yield and the resulting viscosity of gelatian. Keywords: fish bones and skin, gelatin, leubimNaOH.
