Corn hair (Zea mays L.) is an extension of the stigma of the female flower of the maize plant. So far, the use of corn hair, which is a waste from corn cultivation, is limited as a medicine for urinating and lowering blood pressure. The chemical composition of corn hair has the potential to be used to reduce cholesterol levels in the blood because of the presence of beta-sitosterol in it. Based on research it is known that giving corn hair decoction (Zea mays) has a very significant effect on reducing levels of total cholesterol, triglycerides and LDL cholesterol and increasing levels of HDL cholesterol. High levels of HDL cholesterol in the blood (about 40 mg/dl or more) are good for health. Conversely, a high LDL level (100 mg/dl or more) is a bad sign. The buildup of LDL on the walls of blood vessels can cause hardening of the walls of blood vessels which can cause hardening of the walls of the arteries (atherosclerosis) and block blood flow which can be fatal because it triggers disease. coronary heart disease and stroke.
Blended learning is an effective learning and efficient model that can be used during an pandemic Covid-19. One of the LMS available for online learning is E-Learning. This research produced e-learning based on individual rotation guided inquiry of colloid material in the learning process. To obtain an effective product, this research is carried out starting from identification, design, development and dissemination. The research carried out with the model with research and development (R&D) methods using a 4D development model. The E-learning products from this study were validated by four Chemisty teachers and the analysis of validity and praticality tests was carried out by 3 teachers and 10 students then analyzed using the kappa cohen formula. The kappa values obtained from the validity of the construct and the validity of the content are 0.88 and 0.89 with very high categories. The practicality results of students and teachers were 84.38 and 87.29 with high categories respectively. Based on the results of data analysis, it can be concluded that the E-Learning has valid and practical for use in the learning process.
