DEVELOPMENT OF THE GENETICS ENCYCLOPEDIA AS A LEARNING RESOURCE FOR BIOLOGY IN GENETIC SUBSTANCE MATERIAL FOR CLASS XII HIGH SCHOOL STUDENTS

This study aims to determine: (1) the level of suitable encyclopedia of genetic substances; (2) the assessment of the biology teacher of SMAN 2 Sei Tuan; (3) Students' responses to the encyclopedia of genetic substance for grade XII of Senior High School students. This type of research is a development research with a 4-D product development model that is modified as needed. This
model includes 4 stages, they are: (1) define; (2) design; (3) develop; (4) dissesment. The subject fot try out consists of the material expert, media expert, one biology teacher of SMAN 2 percut sei Tuan, 3 students of SMAN 2 for individual try out, 9 students of SMAN 2 for the small group try out and 25 students of SMAN 2 Percut Sei Tuan in a limited field group try out. The Data of the quality of product development was collected by questionnaire. Data were analyzed with quantitative and qualitative descriptive techniques. The result of the research shows that : (1) the
validation of the material expert team is on the criteria of "very suitable" (83%); (2) he validation of the media expert team is on the criteria of "very suitable" (81.25%); (3) the assessment of biology teacher is on the criteria of "very suitable (very helping)" (96.25%); (4) individual try out is on the criteria "very good" (89.33%); small group try out is on the criteria of "very good"(89.61%); Limited field group try out is on the criteria of "very good" (92.46%), so it can be concluded that the research product development of encyclopedia of genetic substance developed
was suitable to be used as an source of additional learning for grade XII of Science Program or as a support for genetic substance learning in senior high school.
