		abstract={The objective of this research was to determine the physical and chemical characteristics of nata de pina which is produced by adding the concentration of ammonium sulfate and the pineapple part used. This study used a factorial Completely Randomized Design (CRD) with two treatment factors and each treatment was repeated three times. Factor A was the concentration of ammonium sulfate (0.4%, 0.6%, and 0.8%) and factor B was the part of the pineapple (flesh and core of pineapple and pineapple peel). Parameters observed in this study included physical parameters (hardness, thickness, and yield) and chemical parameters (moisture content, pH, and C/N ratio). The data obtained were analyzed statistically using ANOVA. The results showed that treatment A had a significant effect on the yield, thickness, hardness and moisture content. Treatment B had a significant effect on yield, thickness, hardness, moisture content, and pH. The interaction of the two treatment factors had a significant effect on thickness, hardness and moisture content. The best treatment was A2B2 (0.6% ammonium sulfate concentration; pineapple peel) with a yield value of 51.33%, thickness 5.65 mm, hardness 632.27 gf, moisture content 95.68%, pH 3.33, and C/N ratio 22.12.}
