Abstract

This Reseach aims to study the effect of variation and dose morinda fruit that most effective applicable to mortality gold snail disease, to use product of research as design source study of biologi Junior High School class VIII. Researching on education Laboratory Muhammadiyah Metro of University at November 2012. The design of research employs analisis of varians non-parametrik with Kruskal-Wallis test with four treatments an three time replication. First treatments is control (not having dose), second consentration 50gr/L, third consentration 100gr/L, and fouth consentration 150 gr/L. Product of research to indicated morinda fruit effective to mortality gold snail  disease. Indication is transformation of occured such as descend activity of consume food and mobility, operculum to close, having mucus, not respons, and according  part soft of body to transformation of color to be chalky color or bad color, body of snail to exit for the hard outer layer of body skin, and the gold snail floating on a top suface. This condition indicate that a chemical composite saponin in morinda fruit to affect the process of chemical in a organism, central nerve, and respiration of gold snail.Kata Kunci: Buah mengkudu, mortalitas keong mas, sumber belajar biologi.

Abstract

Against the background of the limitations of learning media in facilitating the learning needs of students, as well as the importance of critical thinking skills and science literacy in facing global challenges. The independent curriculum is an approach designed to meet the learning needs of students flexibly, but still requires the active role of teachers in conveying essential concepts, so the development of SSI-based e-LKPD is expected to be an effective learning innovation to develop students' critical thinking skills and science literacy. The purpose of the study is to measure the effectiveness of SSI-based e-LKPD on environmental pollution materials on students' science literacy and critical thinking. The use of the liveworksheet application is used for interactive learning media. This type of research is quasi-experimental design with the one group pretest-posttest design method. The research was conducted in grade VIII of junior high school in Tanggamus district with a total of 128 students. Data analysis uses n-gain test and t-test. The results of the analysis obtained an n-gain of 33 in the control class and 53 in the experimental class. This value is in the range of 40-55 with the category of less effective. Furthermore, the results of the t-test showed a significant difference between the control and experimental classes (p<0.05); reject H0, thus that SSI-based e-LKPD is effective in improving critical thinking skills and science literacy of junior high school students.
