Abstract

The present study by investigating an alternative approach integrating natural materials to create more contextual and meaningful learning experiences. A quasi-experimental design was employed, with the experimental group engaging in hands-on laboratory projects using natural indicators such as purple cabbage extract, eggshell waste, and vinegar, while the control group received conventional instruction. Independent t-test analysis revealed a significant difference between the groups, with the experimental group outperforming the control group in post-test assessments of scientific literacy and critical thinking. These findings indicate that incorporating environmentally friendly, context-based materials into chemistry education could effectively enhance essential skills. Moreover, the project-based approach encouraged students to apply scientific concepts, think critically, and relate their learning directly to everyday life.

Abstract

Based on the initial reflection at SMK Negeri 1 Sukawati, it was found that there was a problem, namely the low ability of grade X DKV 2 students at SMK Negeri 1 Sukawati to write Wrehastra script. Based on interviews with Balinese language teachers, this was also caused by the lack of innovative learning models that were suitable for the students' learning climate. The purpose of this study is to determine the effectiveness of the TGT (Team Game Tournament) cooperative learning model using Balinese online comic media in improving student learning achievement and response. Data was collected using interview, observation, and test methods, then analysed using descriptive statistical methods. The research design consisted of N-cycles comprising (1) planning stage, (2) action implementation stage, (3) observation stage, and (4) reflection stage. The TGT (Team Game Tournament) cooperative learning model assisted by Balinese online comic media can improve the ability to write Wrehastra script among students in class X DKV 2 at SMK Negeri 1 Sukawati in the 2023/2024 academic year. This is evidenced by the average test results in Cycle I of 64.75 or 30.7% with a satisfactory rating, and an increase in Cycle II to 83.49 or 96.1% with a good rating. Responsiveness also improved, as evidenced by the average score in Cycle I of 69.15 or 34.6% with a satisfactory rating, which increased in Cycle II to 83 or 96.1% with a good rating.

Abstract

One of the challenges in environmental conservation is the lack of innovative and culturally-based approaches capable of reaching diverse segments of society. The aim of this study is to explore the use of wayang kulit as a communication medium to support sustainable wetland management. The research object is the performance of Wayang Cenk Blonk Series 29: Reklamasi Teluk Benoa. The data source comes from the dialogues between wayang characters referencing the reclamation of Teluk Benoa, presented by the dalang (puppeteer) I Wayan Nardayana. Data collection techniques employed include participant observation, documentation, and interview. The findings of this study will be presented descriptively and argumentatively. Data validity is ensured through source and method triangulation. Wayang Cenk Blonk Seri 29 meets the parameters of effective communication in delivering messages related to the reclamation of Teluk Benoa with the categories of clarity, conciseness, completeness, consideration, and concreteness. Reclamation involves actions taken by individuals to improve the value of land resources, considering both environmental and socio-economic factors, through processes such as filling land, draining, or drying it. The mangrove forest ecosystem is highly fragile and vulnerable to damage, which can occur through direct mechanical actions, such as cutting or dismantling, draining, and drying it. Reclaimed land tends to lower the organic matter and nitrogen content of the soil. Reclamation also results in a decrease in the total microorganisms, fungi, and soil respiration.
