Abstract

This research aims to determine the effect of Moringa oleifera Lam. leaves extract on quality of nata de coco. The research method used is the experimental method with a completely randomized design (CRD) consisting of five treatments and five replications. The treatment consisted of P0 (control), P1, P2, P3 and P4, which were concentrated as follows 0%, 25%, 50%, 75%, 100%. The data was analyzed with ANOVA and continued with Duncan’s Real Differences Test (DRDT) and organoleptic data was analyzed with Friedman Conover test. The results showed that addition of Moringa oleifera leaves extract had a very significant effect on the thickness and yield of nata with F count values 10,88 and 5,07, but the levels of nata de coco fiber was not significantly effect with F count 2,03. The treatment of P2 (50%) is the best treatment to increase the thickness and yield of nata. The level of consumer preference for taste and texture OF nata shows a significant effect with the T values 8,14 and 13,66, while the level of consumer preference for nata color shows no significant effect with the T value 0,51. The P2 (50%) and P4 (100%) treatments were the best treatments for level of taste and texture. Based on these results, it was concluded that addition of 50% Moringa oleifera leaves extract was the recommended treatment for improving the quality of nata. The informations of this research was expected to be an alternative of contextual example in Biology learning XII class 2nd semester in Basic Competence 3.10 and 4.10 about Biothecnology. The result of this research will be donated in the form of learning tools (Syllabus, lesson plans and student work sheet).
