Abstract

Vitamin C is one of the nutrients that act as antioxidants and effectively overcome free radicals that can damage cells or tissues, including protecting the lens from oxidative damage caused by radiation. Vitamin C is widely found in fruits, and vegetables, one of them in chili. Vitamin C in chili has a function as a good antioxidant for the body (able to increase the immune system absorbed by calcium in the body. This study aims to determine the levels of vitamin C contained in some types of chili using UV-Vis spectrophotometry method and conduct a preliminary test. The highest levels of vitamin C obtained by using spectrophotometric method at 200 nm wavelength were on red curly pepper (50 g/100 g) and followed by chili jablay orange-red (38 g/100 g), green cayenne (29 g/100 g), red pepper large (22 g/100 g), and large green chili (9 g/100 g). While based on preliminary test it was found that all chilies contain saponins, as well as only large red pepper (sample 1) and red curly pepper (sample 4) containing flavonoids Keywords: capsicum, chilly, spectrophotometry

Samples were taken using purposive sampling technique, elected class X4 (control class) and class X7 (experimental class). Early knowledge of data collection techniques done by giving a test at the beginning of learning  while learning outcome data obtained from the results of the test at the end of learning data analysis technique is descriptive analysis, inductive and hypothesis testing using t-test analysis and Anova Two-Way. The result of data analysis showed that: (1) students who are taught by discussion method with  Mind Mapping media had significantly higher results than students taught through the convensional discussion method with Sig. = 0.025 less than the value of α = 0.05 (Sig. < α), (2) learning outcomes the high prior knowledge of students had significantly higher compared to students who had low prior knowledge with Sig. = 0.000, less than the value of α = 0.05 (Sig. < α) and, (3) there was not interaction between discussionmethodwith Mind Mapping media and prior knowledge toward students learning outcomes. with Sig. = 0.618 higher than the value of α = 0.05 (Sig.> α). Based on these results it is suggested to economics teachers to use discussion method with Mind Mapping media to improve student learning outcomes.
