DEVELOPMENT OF PROJECT BASED LEARNING SUBSTANCES ON TOPIC SOLUBILITY AND SOLUBILITY PRODUCT IN SENIOR HIGH SCHOOL

Development of teaching substances aimed to find teaching topics used fulfill the criteria BSNP, knowing that student
learning outcomes using project-based teaching substances module higher than the KKM, and to determine the development
aspects of effective and psychomotor aspects of students. Type of research was the development of Research and Development
(R & D) with a pretest-posttest design one group (One Group Pretest-Posttest Design). The population in this study were all
UNIMED chemistry professor who teaches General Chemistry, the whole chemistry teacher SMA Negeri 1 Galang and all
students of class XI MIA Semester II SMA Negeri 1 Galang which consists of three classes school year 2015/2016. Samples were
determined by purposive sampling for teaching substances module and random sampling to take a class that is used as the
experimental class. This study used questionnaires and objective test instruments as much as 20 questions that have been on
test validity, reliability, level of difficulty, different power and distruktor. The results showed BSNP teaching substances fulfilled
the criteria, data were obtained: Feasibility Content (3.26), Feasibility Languages (3.26), Feasibility Presentation (3.23) with valid
criteria and do not need revision. For learning outcomes data analyzed by t the right. Results of t-test for learning outcomes
obtained t > t table ( ) (15.989> 1.699). Based on the analysis of data, then Ho is rejected and Ha accepted, namely: chemistry
student learning outcomes that learned to use a project-based teaching materials module higher than the KKM (70). Value
affective and psychomotor student is also growing, to the average value of affective student is + 66.11 and an average value
that is + 70.70 psychomotor students.
