Abstract

The purpose of this study was to prove that the Banana Leaf Extract can hinder the process of browning in potato tuber. The research was conducted in November 2018 in the Laboratory of Botany, Departement of Biology, Faculty of Mathematics and Natural Sciences, University of Lampung. This study useds a completely randomized design (CRD) with 5 levels degree of concentration of Banana Leaf Extract: : 0% v/v (control), 5% v/v, 10% v/v, 15% v/v, and 20% v/v. Browning index is determined based on the absorbance of the extract of potato tuber at a wavelength of 420 nm. Total soluble carbohydrate content was determined by phenol-sulfuric method, while estimating dehydrogenase enzyme activity by methylene blue method. Levene test for homogeneity, analysis of variance and HSD test was carried out at 5% significance level. The result showed that the Banana Leaf Extract browning index lowered by 0,50 in concentration of Banana Leaf Extract 7,45% v/v. The correlation was coefficient is 0.71 which shows a strong relationship between the concentration of Banana Leaf Extract with the browning index of potato tuber in quadratic equation (y = 0,0007x2 - 0,0103x2 + 0,5378). Banana Leaf Extract did not significantly affect total soluble carbohydrate content in potato tuber and dehydrogenase enzyme activity. The final conclusion was that Banana Leaf Extract have anti-browning characteristic on the potato tuber.
