- This study aims to determine the effect of the ratio of juice fruit dragon - sugar on the physical properties of chemical and organoleptic jelly and to get the ratio of juice dragon - sugar were giving out the best impact on the physical, chemical and organoleptic jelly and to determine levels of Anthocyanins and vitamin C dragon fruit before and after process into jelly. The research was conducted from March to May 2017 in the Laboratory of Agro-Industry Faculty of Agriculture, Tadulako University. This study used a completely randomized design (CRD) 1 factor.
