Abstract

Clean water is a fundamental necessity; however, many regions still struggle to access it due to contamination by suspended particles, organic matter, and harmful microorganisms. This activity aims to strengthen the practical competence of Biology Education students at Universitas Negeri Medan through training in making simple water filters. The training was conducted through demonstrations and simulations using turbid water from the Tembung River as a sample. The filter was constructed from readily available materials such as used plastic bottles, cotton, tissue, sand, small gravel, and palm fiber arranged in layers. The results showed that the filter effectively reduced water turbidity and enhanced students’ skills in clean water treatment technology. The training also encouraged students to develop 21st-century skills such as critical thinking, problem-solving, and collaboration, while preparing them as future educators capable of raising community awareness about the importance of maintaining water quality. Therefore, this training has the potential to be developed as an applicative environmental education model that contributes positively to clean water provision.

Abstract

Chemistry education on colloid systems presents persistent challenges due to the abstract and submicroscopic nature of the concepts involved, which conventional instructional methods struggle to address effectively. This study aimed to develop Augmented Reality (AR)-based chemistry learning media integrated with local wisdom for colloid system instruction, evaluate its validity and practicality, and measure its effectiveness in reducing misconceptions and improving students' learning outcomes. Using the ADDIE development model with a one-group pretest-posttest design, the study was conducted at SMA Swasta Methodist 7 Medan involving 26 students of class XI IPA. The developed media consisted of two AR marker-based learning tools: AR Link 1 covering dispersed substances, dispersion media, and colloid types contextualized through local cultural examples such as gulai and teh talua, and AR Link 2 visualizing colloid properties including Brownian motion, the Tyndall effect, coagulation, dialysis, adsorption, and electrophoresis through animated microscopic representations. Validation results showed average scores of 4.4 (content) and 4.3 (language) categorized as valid, and a perfect score of 5 (very valid) across all media aspects. The instrument validation reached 93.1%, categorized as highly feasible. Student learning interest ranged from good to very good (74.04%–80%), and observation data confirmed active participation (75%–95%). The N-gain score of 0.64 indicated moderate improvement in conceptual understanding, while posttest results demonstrated substantial reduction of misconceptions across all colloid concepts. The AR-based media integrated with local wisdom was concluded to be valid, practical, and effective for colloid system learning.
