THE DEVELOPMENT OF “SEMESTA SAINS” BOOK TO IMPROVE SCIENCE LITERACY ABILITY FOR THIRD GRADE PRIMARY SCHOOL STUDENT Linda Pratiwi 1705850 ABSTRACT This study aims to describe the design and development of teaching materials entitled "Semesta Sains", to describe the implementation of these teaching materials, as well as to find out the increase in scientific literacy skills of 3rd-grade elementary school students. The background of this research is the low scientific literacy of school students in Indonesia according to PISA (Program for International Student Assessment). In addition, the development of teaching materials to support the improvement of scientific literacy skills of school students is also still minimal. This research uses the Design & Development (D&D) method of the ADDIE model. This “Semesta Sains” teaching material was validated by experts using a questionnaire to determine the feasibility of the product developed by the researcher. The "Semesta Sains" teaching materials scored 97.5% eligible from material experts and 92.5% eligible from media experts, thus the "Semesta Sains" teaching materials were declared very good (very valid). The implementation of the "Semesta Sains" teaching materials was carried out to 3rd-grade elementary school students and it was found that there was an increase in scientific literacy skills. Therefore, it can be concluded that the "Semesta Sains" teaching materials are suitable for use in learning in grade 3 elementary schools to improve scientific literacy skills
