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 aims to develop a booklet based on research findings on the tissue culture of Sonneratia alba as a learning material for the Modern Biotechnology topic in Grade X of Senior High School under the Merdeka Curriculum. The main problem identified in schools is students’ low understanding of tissue culture due to limited learning resources and the lack of practical laboratory activities. The booklet was developed using the Research and Development (R&D) model with an ADDIE approach simplified into three stages: Analysis, Design, and Development. Primary data were obtained from research on the effects of NAA and BAP hormone combinations on the in vitro germination of Sonneratia alba, which served as the basis for the booklet content. Product validation was carried out by media and material experts using a Likert-scale assessment sheet. The media expert validation obtained a percentage of 100% (very valid), while material expert validation reached 94.1% (very valid). The overall average validity of the booklet was 97.05%, which falls into the very valid category. Thus, the Sonneratia alba tissue culture booklet is suitable for use as a practical, engaging, and relevant supplementary learning resource to enhance students’ understanding of Modern Biotechnology.

Abstract

Rapid technological advancements require teachers and students to be able to utilize electronic learning media to clarify complex and abstract concepts. Biotechnology material for Grade X is considered interesting but relatively difficult to understand because it is multidisciplinary, abstract, and applicative in nature. Survey results indicate several problems, including students’ difficulties in understanding modern biotechnology, difficulty in memorizing bacterial names in Latin, and limitations of practical activities in schools due to constraints in time, equipment, materials, and laboratory facilities. This study aims to develop a multimedia electronic magazine as a solution to facilitate understanding of biotechnology material and to provide virtual practical experiences. This study employed a Research and Development (R&D) method using the ADDIE model, conducted up to the development stage. Expert validation resulted in an average score of 3.55 (very valid), the first-stage trial involving university students obtained a score of 3.74 (very good), and the second-stage trial involving students obtained a score of 3.55 (very good). In conclusion, the developed multimedia electronic magazine is of very high quality with an average score of 3.62 and can be implemented in Grade X senior high school biotechnology learning.
