Abstract

Abstract This research aimed to describe the development of worksheet in the experiment of creating indicator papers from sambaing colok plants and analyze the results of the feasibility test on the format of the worksheet. The development phases consist of analyzing the concept of base acid and literature on indicator papers made from sambaing colok plants and creating worksheet, as research product, to be used in experiment for making indicator papers. The feasibility test was conducted on the format of the worksheet and the results have met the requirements (very valid). The average rcount score of 0,92 and the average feasibility percentage of 92% were gained from the validators. The average rcount score of 0,93 and the average feasibility percentage of 93% were gained from the students. Therefore, based on the scores, it can be concluded that the worksheet can be used by students as a learning aid when conducting experiments.
