Abstract

Genetic concepts, particularly DNA technology, often lead to misconceptions among students. Integrating a virtual laboratory (VL) into coursework presents an innovative approach to enhancing concept understanding and visual literacy through interactive, story-based simulations that bridge theory and practice. This study aimed to analyze the students' concept understanding and visual literacy improvement by applying a VL to teach DNA Test Simulation (Paternity Test) using a contextual narrative method. The research was conducted in the Science Education undergraduate program with a purposive total sampling of students enrolled in Genetics (First Semester 2024/2025), utilizing an open-source web-based VL platform. Pretest and posttest assessments measured students' concept understanding and visual literacy before and after VL integration. The findings reveal a significant improvement, with concept understanding rising from an average pretest score of 42.6 to posttest 69.9 (N-Gain 0.46) and visual literacy increasing from 53.8 to 71.8 (N-Gain 0.37). Furthermore, 97% of students were satisfied with the VL-based learning method. This research contributes to knowledge and science development by demonstrating that VL can improve concept learning and visual literacy in genetics education. It offers an accessible and scalable solution for teaching complex DNA technology concepts, reducing reliance on costly wet laboratory experiments while maintaining scientific rigor. Beyond academia, the study supports broader educational equity, making advanced molecular biology concepts more available to diverse learners and fostering scientific literacy in society.

Abstract

Abstract Peron Village located on the western slopes of Mount Ungaran at an altitude of 700 meters above sea level, is in the upstream area of the Bodri Watershed, a priority watershed. Despite implementing an agroforestry system that combines forestry and agricultural crops, local farmers still rely heavily on synthetic herbicides containing glyphosate for weed control. This dependence poses serious risks to water quality, aquatic ecosystems, and the health of communities that rely on spring water. This community service program aims to improve ecological literacy and practical skills in making environmentally friendly herbicides using local ingredients such as coarse salt, vinegar, and sulfur. The activity was held at the Peron Village Hall with 25 participants representing the hamlets. The program included socialization of the concept of agroforestry, the theory of natural herbicides, and the practice of making organic herbicides using 1 liter of clean water, 500 g of coarse salt, 0.75 ounces of sulfur, and 100 ml of vinegar. The results showed that participants successfully produced an effective natural herbicide that controlled weeds within two days, albeit slower than synthetic herbicides, without damaging soil structure or polluting water sources. This success opens up opportunities for further development by utilizing agroforestry waste such as coffee husks as active ingredients, supporting the zero-waste concept and increasing the economic value of local commodities. This program aligns with the Sustainable Development Goals and can be replicated in other agroforestry areas in Indonesia.
