Abstract

Purpose of the Study: This study aimed to develop and validate an innovative electronic pocketbook on plant-like protists, designed for use by class X Senior High School students. The pocketbook integrates real-world examples of phytoplankton research from the Teluk Nibung River, offering a modern and engaging learning tool that enhances students' understanding of plant-like protists. Methodology: The research employed a Research and Development (R&D) method, encompassing three stages: pre-production, production, and post-production. Validation was conducted using questionnaire sheets with a Guttman scale, assessed by two lecturers. Additionally, media validation sheets, covering format, content, language, and practicality, were evaluated using a Likert scale by two lecturers and three biology teachers. Main Findings: The electronic pocketbook contains comprehensive material on plant-like protists, enriched by real phytoplankton research results from the Teluk Nibung River. The pocketbook includes essential components such as cover, preface, instructions, table of contents, material content, bibliography, glossary, and author profile. The validation results yielded a CVI value of 1.00, indicating that the pocketbook is valid and suitable as a learning medium for plant-like protists in class X biology. Novelty/Originality of this Study: This study presents a unique approach by integrating phytoplankton research into the curriculum through a digital format. The electronic pocketbook offers flexibility by being accessible both online and offline, and can be downloaded using free applications, providing students with a practical and innovative tool for learning. The incorporation of real-world data not only enhances engagement but also bridges the gap between theoretical knowledge and field research.

Abstract

Teluk Nibung River in Batu Ampar District, Kubu Raya Regency is a transportation route for Mangrove Production Forests and a traditional fishing area for local communities. The community structure of phytoplankton in the Teluk Nibung River has never been reported. As the main producer in the waters food chain, the structure community of phytoplankton indicates the quality of the fertility of the waters. The community structure of phytoplankton can be identified by measuring the index of abundance, diversity, evenness and dominance. The survey method was used at three stations in dry and rainy seasons. Sample collection is using net plankton (30 µm) and preserved in 4% formalin. The physico-chemical factors measured included temperature, pH, brightness, current velocity, salinity, dissolved oxygen and CO2, phosphate and nitrate. Once identified, phytoplankton calculations are performed to obtain abundance, diversity, evenness, and dominance values. The species number of phytoplankton found was 56 classified into 6 classes, namely Bacillariophyceae (34 species), Dinophyceae (12 species), Chlorophyceae (4 species), Cyanophyceae (3 species), Xantophyceae (1 species), and Euglenophyceae (2 species). The highest abundance of phytoplankton was in the Bacillariophyceae class with a range of 583 Ind./L at Station 2 in the rainy season to 3.922 Ind./L at Station 3 in the dry season. The diversity index at the three stations and both seasons is in the moderate category with a range of 2.31-2.46. The evenness index at the three stations and both seasons is in the high category with a range of 0.67-0.73. Low dominance level was found at the three stations and both seasons with values ranging from 0.14 to 0.19. Overall, the community structure of the phytoplankton in the Teluk Nibung River is in relatively good condition and can support the life of the aquatic biota in it.
