Abstract

Islamic integrated learning media innovations need to be improved so that the chemistry learning process becomes more interesting. This research is expected to produce an integrated Islamic acid-base learning media in Lectora Inspire media that is valid based on the validity of material experts, media experts, teacher practicality tests and student responses and their application in class. The model in this Research and Development (R&D) research is a 4-D model, namely Define, Design, Develop, and Disseminate. The location of the research was conducted at the 10th State Senior High School (SMAN) Pekanbaru. The results of the research in the form of an integrated Islamic acid-base design on Lectora Inspire media were validated by material experts obtained 92.50% with very valid criteria and media experts obtained 92.50% with very valid criteria and Islamic integration experts obtained 72.5% valid criteria. Draft I was revised based on input from experts. In Draft II the practicality test was carried out by chemistry subject teachers with very practical criteria of 95.33%, and student response test results obtained a very attractive score of 87.29%. From this test, Islamic integrated acids and bases in Lectora Inspire media are suitable for use as learning media in the learning process at school. The last stage was socialization to the Pekanbaru City Chemistry MGMP teachers which resulted in a Very Worthy usage rate for other classes of 94.19%.

Abstract

Free radicals can weaken the function of cell membranes and endoplasmic reticulum and destroy cells at the DNA molecular level. The human body needs antioxidants to stabilize the number of free radicals in the body. Natural antioxidants found in plants include vitamins, phenols, flavonoids, and carotenoids. Sappan wood is a herbal plant that has antioxidant properties. The antioxidant compounds contained in sappan wood are phenolic compounds, resorcinins, brazilein, gallic acid, flavonoids, saponins, terpenoids, and tannins. The method used is a literature study which is reviewed one by one, after which the journals obtained are collected and the information is compiled by summarizing the contents of the journals used as sources. From the processed data, sappan wood has an antioxidant activity which can be seen from the In Vitro test with the IC50 value and the In Vivo test on rats. Sappan wood is used as a cosmetic ingredient in the form of essence and hair tonic. Apart from that, it is also used as an ingredient in the manufacture of drinks and food because sappan wood has high antioxidants.

Abstract

The research development of STREAM-based blog learning media on periodic system element material was conducted to determine the feasibility as a learning media product.  It used Research and Development design with 4D Model.  The development results were validated by two expert validators, one practitioner validator and ten students of State Senior High School 1 Tembilahan as students limited test validators. The feasibility validations of quantitative data were analyzed by using percentage and the qualitative data (responses and suggestions) for validators’ improvement were used as considerations for making revisions.  Generally, the validators’ assessments of the development of STREAM-based blog learning media obtained that the mean percentage of validity results from material and media experts were 92.15%, the practicality test by the chemistry teacher was 94.33%, and the limited response test by the students were 87.6%.  So it could be concluded that the STREAM-based blog learning media was feasible to use in learning activities.
