Abstract

This study aims to determine the validity of the design of an E-Booklet on Hydrocarbonoclastic Bacteria in Petroleum Wastewater for biodiversity material for Grade X senior high school students. The research method used was descriptive qualitative with the ADDIE model consisting of five stages, namely Analyze, Design, Development, Implement, and Evaluate; however, the E-Booklet design in this study was carried out only up to the Development stage. The E-Booklet design stage was conducted at the Biology Study Program, Faculty of Teacher Training and Education, Bina Widya Campus, Universitas Riau. The designed E-Booklet was then validated by two validators, namely a media expert and a content expert. The validators’ assessment of the E-Booklet was based on E-Booklet validity indicators consisting of three aspects: content, language, and format and graphics. The validity results of the E-Booklet design on Hydrocarbonoclastic Bacteria in Petroleum Wastewater obtained an average validity score of 3.84, indicating that the E-Booklet design falls into the very valid category and can be used as enrichment teaching material for biodiversity content for Grade X senior high school, Phase E.

Abstract

This study was motivated by the low utilization of contextual digital teaching materials in learning environmental change topics, resulting in environmental awareness and students’ critical thinking skills not developing optimally. The study aimed to develop an ecoliteracy-based E-LKPD using Liveworksheets on environmental change materials for Grade X and to describe its validity and practicality levels. The research employed a Research and Development approach using the ADDIE model, limited to the analysis, design, and development stages. Data were obtained through teacher interviews, validation by subject-matter and media experts, and a small-group trial involving 15 students of SMA IT Fadhilah Pekanbaru using a Likert-scale questionnaire. The validation results showed an average score of 79% (valid category) for the material, media, and language aspects, while practitioner (teacher) validation reached 90% (very valid category). The student practicality trial produced an average of 91.5% in the very practical category, viewed from a systematic instructional design, ease of operation, and an attractive and contextual appearance. The integration of cognitive, attitudinal, and skills aspects within the ecoliteracy framework encourages students to analyze environmental problems, develop ecological empathy, and demonstrate responsibility toward the environment. It is concluded that the developed ecoliteracy-based E-LKPD is valid and highly practical for use as an alternative digital teaching material to support the implementation of the Merdeka Curriculum and the strengthening of the environmentally oriented Pancasila Student Profile.
