Abstract

SYADINDA BAROKAH: The Effect of Ratio of Red Beet Pulp with Pinneaple pulp and Percentage of CMC on Jam Quality, Supervised by LINDA MASNIARY LUBIS. The aim of this study was to determine the effect of the ratio red beet pulp with pinneaple pulp and percentage of CMC on quality jam. The method used in this study was the factorial Completely Randomized Design (CRD) method with 2 factors, the ratio of red beet pulp with pinneaple pulp (P): (100%:0%, 90%:10%, 80%:20%, 70%:30%) and percentage of CMC (R): (0,5%, 0,75%, 1,0%). The parameters observed were moisture content, ash content, total acid, crude fiber content, acidity (pH), total soluble solid, vitamin C content, total microbe, syneresis and organoleptic by hedonic value of color, aroma, taste, texture, spreadability and general acceptance. The result showed that the ratio of red beet pulp with pinneaple pulp had a highly significant effect on moisture content, ash content, total acid, crude fiber content, acidity, total soluble solid, vitamin C content, total microbe, syneresis, organoleptic by hedonic value of aroma, taste and general acceptance. Percentage of CMC had a highly significant effect on moisture content, ash content, total acid, crude fiber content, acidity, total soluble solid, vitamin C content, total microbe, syneresis, organoleptic by hedonic value of texture and general acceptance. Intraction of the ratio of red beet pulp with pinneaple pulp and percentage of CMC had a highly significant effect on total acid, crude fiber content and acidity. Based on the results showed that P4R3 treatment with ratio of red beet pulp with pinneaple pulp 70%:30% and the percentage of CMC 1,0% produced the best quality jam with a water content of 30,1322%, acidity 3,5033, total soluble solid 56,6667 °brix, vitamin C content 22,8390 mg/100g, total microbe 3,2x102 CFU/g, hedonic value of color 5,5905, aroma 5,7212, taste 5,6698, texture 5,7048, spreadability 5,8032 and general acceptance 6,0254.
