This study was conducted with the aim to determine the effect of the percentage of pineapple pulp and carrageenan percentage on the quality of green mustard vegetable leather. This research was conducted using a factorial completely randomized design (CRD) method consisting of two factors, namely the percentage of pineapple pulp (N): (20%, 30%, 40%, 50%) and carrageenan percentage (K): (0,3%; 0,6%; 0,9%; 1,2%). The parameters observed in this study were ash content, moisture content, total soluble solids, total sugar, vitamin C content, crude fiber content, color index, organoleptic values of aroma, taste, texture, color and general acceptance. The results showed that the addition of pineapple pulp produced a significantly different effect on ash content, water content, total sugar, total soluble solids, vitamin C content, ˚Hue color, and organoleptic aroma, taste, texture, color and general acceptance. The percentage of carrageenan has a significantly different effect on ash content, water content, crude fiber content, total soluble solids, ˚Hue color, organoleptic texture, and general acceptance.
