Abstract

Biology learning in biotechnology materials already incorporates practical activities, but the limitations of the media and visual representations remain obstacles to students' understanding. Therefore, media development e-comic potentially facilitate learning through a combination of interesting images, text, and stories. This research aims to determine students' eligibility and responses to the media e-comic, which includes biotechnology materials, as well as to explore its potential as an attractive educational resource. This research uses a modified research & development methodology based on Borg & Gall, adapted by Sugiyono. Selecting participants through purposive sampling, involving 20 tenth-grade high school students. This research uses validation sheets and student response questionnaires. The research instrument was validated by 5 expert validators. Using Aiken's V formula to analyze the data collected during the study. Reliability testing using intraclass correlation coefficients. Assessment of student response questionnaires using the Likert scale. Media validation analysis obtained an average value of 0.92, which is included in the valid category. Reliability test showing a reliability value of 0.946, which belongs to the excellent category. The assessment of student responses had an average score of 78.63%, indicating a good category. These results show that the media e-comic biotechnology materials received a positive response from students, and the media e-comic was effectively used in the learning process.

Abstract

This study aims to develop and assess the feasibility of learning video media on the sub-topic of food substances based on the results of an inventory of medicinal plants that increase appetite in toddlers. The research method used is Research and Development (R&D) with reference to the Borg and Gall model which is limited to five stages, namely potential and problems, data collection, product design, design validation, and design revision. Media validation was carried out by five validators using a purposive sampling technique with assessments on aspects of format, content, language, and appearance. Validity analysis uses the Aiken's V formula, while reliability is explained using the Intraclass Correlation Coefficient (ICC) method. The results of the study showed that the learning video media obtained an overall validity value of 0.92 with a valid category. The results of the reliability test showed a value of 0.733 with a moderate category. Based on these results, the learning video media on the sub-topic of food substances is declared suitable for use as a biology learning medium, although further testing is still needed to determine its effectiveness in improving student learning outcomes.

Abstract

Biology learning encompasses complex material, thereby requiring engaging instructional media to enhance students’ understanding. The selection of interesting learning media can increase students’ interest and motivation in the classroom learning process. This study aims to determine the feasibility of a booklet as a learning medium for the reproductive system topic, based on the results of an inventory of traditional postpartum medicinal plants in Teluk Batang Selatan Village, Kayong Utara Regency, West Kalimantan. The research employed a Research and Development (R&D) approach using the Borg and Gall model, which was modified by Sugiyono. The process included five stages: identifying potential and problems, data collection, product design, product validation, and product revision. Data analysis was conducted using Aiken’s V validity index and the Intraclass Correlation Coefficient (ICC) reliability test. The analysis results showed that the average Aiken’s V validity value was 0.94, categorized as very valid, covering the aspects of format (0.91), content (0.97), and language (0.93). The reliability test produced an ICC value of 0.727, categorized as moderate. Based on these results, the developed reproductive system booklet was declared valid, reliable, and feasible for use as a learning medium that integrates scientific concepts with the local wisdom values of the community.
