Abstract

Peat water in Indonesia, abundant in swamp regions, is acidic and rich in humic substances and Fe²⁺ ions, making it unsuitable for direct use. This study explores a sustainable approach to treating peat water using hydrogel synthesized from durian rind (Durio zibethinus), an agricultural waste rich in cellulose. Cellulose was extracted via alkali and bleaching treatment, then crosslinked with chitosan in a NaOH/urea solvent system to form a biodegradable, porous hydrogel. The hydrogel exhibited a swelling ratio of 857% and a gel content of 98.23%, indicating high hydrophilicity and network integrity. Adsorption experiments demonstrated removal efficiencies of 98.96% for methylene blue and 25% for Fe²⁺. The high dye removal at low concentrations suggests strong interaction between hydrogel functional groups (–OH, –NH₂) and organic molecules, while Fe²⁺ removal was attributed to electrostatic interaction and potential chelation. Adsorption followed pseudo-second-order kinetics, indicating chemisorption as the rate-limiting step. These results suggest that durian rind hydrogel is a promising low-cost material for organic and inorganic pollutant removal in acidic water systems. This study highlights the potential of agro-waste valorization in developing eco-friendly materials for water purification.

Abstract

The conventional printed modules used in schools have not been able to make students active and understand chemical concepts. Therefore, it is necessary to develop an interactive multimedia-based e-module grounded in Project Based Learning (PjBL), equipped with videos, images, and interactions to engage students and facilitate easier comprehension of chemical materials. The iam of this study is to improve the learning outcomes of class XI Science Muhammadiyah 1 High School Pontianak. The method used in this research is development (research and development) employing the ADDIE model, which includes the stages of (analysis, design, development, implementation, and evaluation). The research findings indicate very high criteria with an average validity coefficient of 0.93 for each aspect of media, materials, and language. The practicality analysis, based on the response questionnaires from the small group trial and the main field trial, showed practicality values of 71% and 74%, respectively, both with practical criteria. It can be concluded that the project based learning e-module developed is feasible to be used as an effective and practical learning tool for XI Science students and chemistry teachers in high schools.
