Abstract

Citizen Science is considered a way to improve the relationship between research, education, and action by involving non-professionals in scientific research. Through Citizen Science, students will be trained to think critically and construct scientific arguments based on data and evidence they collect on their own. However, the scientific argumentation ability of students in several high schools in Region III of Cirebon is still relatively low. Based on the results of surveys and interviews with Biology teachers in the region, learning is still dominated by the Teacher-Centered approach, where the learning process is more teacher-centered. This research is a descriptive qualitative research conducted to determine students' perceptions of Citizen Science's contribution to scientific argumentation skills on environmental change and sustainability, using a descriptive method. The population in this study is MA and SMA in the Cirebon City/Regency area, while the schools sampled in this study are SMA Negeri 1 Source, SMA Negeri 8 Cirebon City, and MA Salafiyah Cirebon City. The data collection techniques used in this study are structured interview techniques and questionnaires, and based on questionnaires and interviews there are a variety of answers obtained, but in general many students are new to Citizen Science, and students' interest in agreeing to the Citizen Science hypothesis can improve scientific argumentation skills and critical thinking skills, in addition to the level of relevance between Citizen Science and environmental change and sustainability materials have great potential to be implemented.

Abstract

The increasing use of plastic materials in daily life has led to a rise in plastic waste, contributing significantly to environmental pollution. This study aims to analyze the characteristics of insects that contribute to the eco-friendly degradation of plastic waste and to evaluate the rate of plastic waste degradation and the waste reduction index (WRI) achieved through insect larvae. The research uses a Randomized Factorial Design, investigating plastics such as styrofoam blocks, low-density polyethylene, polyurethane, polystyrene, and a control. The parameters examined include insect characteristics, larval length and weight, degradation rate, and WRI. Both Zophobas atratus and Tenebrio molitor exhibit the potential for the bioconversion of plastic waste. The weight of T. molitor larvae ranges from 0.07-0.09g, while Z. atratus larvae weigh between 0.51 and 0.60g. The WRI is directly proportional to the reduction rate, with higher reduction rates corresponding to higher WRI values. The results showed that the control using Z. atratus and T. molitor larvae achieved the highest WRI values among all treatments. Among the plastic types studied, styrofoam blocks showed the highest WRI value, indicating that a feeding rate of 1g of plastic per larva per day is optimal for efficiently reducing plastic waste. This supports circular economy initiatives for companies developing insect-based proteins for food, feed, and natural products while advancing sustainable development goals.
