Development of integrated science textbooks on local potential food Bakpia for junior high school

Abstract

This study aimed to (1) determine the feasibility of developed science textbooks by expert validators; (2) knowing the results of the readability test by junior high school teachers and student. This research was a development study used a 4D modification model which consist of define, design, develop, and disseminate. However, this development was carried out until the develop stage. The product was validated by a material expert and media expert validator. The readability test was conducted by three science teachers and fifteen junior high school students. Data were collected using a validation and readability test questionnaire. Technical analysis of data used quantitative descriptive percentage analysis. The results showed that the feasibility of the material was 81.26% with very good criteria, the percentage of the student's media feasibility was 89.06% with very good criteria the percentage of the teacher's media feasibility was 91.67% with very good criteria. The percentage of readability test results by the science teacher was 96.35% with very good criteria, and the percentage of readability tests by junior high school students was 85.67% with very good criteria. As a whole the science textbook integrated the local potential of bakpia can be used in the science learning process.
