Abstract

Microplastics and the extensive use of single-use plastics have become growing environmental issues that threaten human health and ecosystem sustainability. Limited environmental literacy among adolescents contributes to the continued high consumption of single-use plastics in school settings, highlighting the need for effective environmental education programs. This community service activity aimed to improve students’ environmental literacy regarding the dangers of microplastics and the importance of reducing single-use plastic use through an environmentally friendly school program at Al-Razi Sinar Harapan Vocational High School, Medan. The program involved 58 students and was implemented through interactive educational sessions, group discussions, simple demonstrations on plastic pollution, and campaigns promoting the use of reusable tumblers and food containers. Evaluation was conducted through participatory observation and assessment of students’ responses during discussions and question-and-answer sessions. The results indicated that participants were able to explain the concept of microplastics, identify common sources of plastic pollution within the school environment, and propose practical alternatives to reduce single-use plastic consumption, including the use of reusable containers, tumblers, and cloth bags. Increased participation during discussions, improved ability to answer questions related to the educational materials, and students’ expressed commitment to adopting environmentally friendly practices served as indicators of enhanced understanding and environmental awareness following the program. The activity also received positive feedback from teachers and school administrators and contributed to fostering a cleaner, healthier, and more sustainable school environment.

Abstract

Background: Peripheral Blood Smear (PBS) examination is a crucial hematology test for evaluating blood cell morphology, particularly that of erythrocytes. The quality of the results is heavily influenced by pre-analytical stages, one of which is the fixation process. Variations in fixation time can affect erythrocyte morphology and staining outcomes; therefore, a proper understanding of the correct procedure is essential. This outreach activity aimed to enhance participants' knowledge and understanding regarding the impact of varying PBS fixation times on erythrocyte morphology when using Giemsa staining. The activity began with a preparation phase involving coordination between the organizing team and the institution regarding the schedule, venue, provision of equipment and materials, and the development of educational content. The implementation phase commenced with participant registration and the opening of the event by the moderator. Following the presentation of the material, a laboratory demonstration was conducted. The organizing team showcased PBS preparations created using methanol fixation times of 1, 3, 5, and 10 minutes. The results indicated that the participants' average knowledge level rose from 59.3% prior to the activity to 95.0% afterward, representing an average increase of 35.7%. The most significant improvement was observed in the understanding of how fixation time variations affect erythrocyte morphology, rising from 47% to 92% (a 45% increase). Appropriate fixation times yielded clearer erythrocyte images, intact cell shapes, and even color distribution, whereas fixation times that were too short or too long compromised the quality of the preparations. This activity successfully broadened participants' insight into the importance of standardizing the fixation process in hematology testing to ensure accurate results that support rapid and precise diagnoses.
