Interactive Multimedia-Based Learning Materials Innovation for Teaching Basic Techniques in Analysis

This study aims to determine the basic technical
teaching materials in the analysis of basic analytic chemistry
course that has fulfilled the BSNP eligibility. This research falls
into the realm of research and development with the development
model Analysis-Design-Development-Implementation-Evaluation
(ADDIE). Samples were selected using a purposive sampling
technique. The sample in this study were two student handbooks
commonly used in the Faculty of Mathematics and Natural
Sciences State University of Medan Basic Analytical Chemistry
courses and two classes in the Department of Chemistry Faculty
of Mathematics and Natural Sciences State University of Medan
as many as 40 students. The research data were then analyzed
using SPPS 21.0 for windows through tests of normality,
homogeneity, and t test. Through the normality test it was found
that the significance of the data > 0.05, homogeneity testing
showed that from the pretest data of the two prices obtained a
probability value> α 0.05, and the results of hypothesis testing
with a value of tcount 7.101 and t table 1.68. The conclusion is
that the hypothesis be accepted. The results showed that (1) The
feasibility level of innovative multimedia-based interactive
chemistry teaching materials for teaching basic engineering
materials in the analysis was feasible to use, the average
acquisition value of the four aspects was 3.60. (2) There are
differences in student learning outcomes using multimedia-based
interactive chemistry teaching materials for teaching basic
techniques in the analysis that have been developed with student
learning outcomes using student handbooks at Faculty of
Mathematics and Natural Sciences State University of Medan
