Potensi Pemanfaatan Ekstrak Kubis Ungu (Brassica oleracea L.) sebagai Indikator Asam Basa Alami
Abstrak: The study of
potential use of extracts and fractions of purple cabbage (Brassica oleracea
L.) as an indicator of acid-base has been conducted. This research aims to
determine the color change at a certain pH to extract total, n-hexane, ethyl
acetate and methanol fraction. Based on the results of the test changes color
only total extracts and methanol fraction that is suitable as indicator.
Statistical test that the t test for total titration end point extracts, t
calculate is smaller than t table [0.4241 <2.776], it showed no significant
difference between the endpoint using the total extract with bromine thymol
blue indicator. While the endpoint for methanol fraction having t
calculategreater than t table [6.323> 2.776],indicating the end point of the
titration using methanol fraction was significantly different compared with
bromine thymol blue indicator.
