Abstract

Purpose: The purpose of the Arga Math program is to introduce and implement the “Plakat” (Rank Number Board) as an innovative teaching aid to enhance students’ mathematical understanding, specifically in exponentiation. This visual tool aims to foster student engagement, simplify abstract concepts, and support teachers in creating more interactive and effective learning environments. Methodology/approach: The socialization activity was conducted at MTS Sinoa using a service-learning approach focused on knowledge transfer. The session began with a brief presentation on the concept and function of Plakat Teaching Aid. This was followed by hands-on practice, where participants applied the tool to solve exponent-related problems. Feedback and perceptions were collected through a structured questionnaire completed by teachers and students after the activity. Results/findings: The results of the activity showed that the Plakat teaching aid helped both teachers and students better understand exponentiation. Students demonstrated increased enthusiasm and confidence in solving exponential problems, while teachers acknowledged the usefulness of the tool in delivering abstract content. Furthermore, the activity motivated educators to design similar instructional media that aligned with curriculum objectives and encouraged creativity in teaching mathematics. Conclusions: The Arga Math Plakat proved to be an effective visual learning aid, making abstract mathematical concepts more accessible. It positively affects learning outcomes and inspires both students and educators. Limitations: The activity had limited reach due to time constraints and the participation of only 13 eighth-grade students, with minimal involvement from other educators. Contribution: This initiative supports educational innovation and contributes to achieving SDG Goal 4: Quality Education.

Abstract

Lactic acid (LAB) is a bacteria involved in food fermentation and can be used as a probiotic to provide health benefits for those who consume it. This research aims to bring innovation and added value, and improve the community's utilization of probiotics (LAB) from husks and black rice from Toraja. The method used is collecting and processing samples, isolation and purification of LAB, microscopic and macroscopic identification, testing the activity/potential of LAB (Kirby Bauer), and molecular identification of 16S rRNA (sequencing). This study has confirmed that fermented rice has Lactococcus taiwanensis type lactic acid bacteria, while fermented husk is not a type of lactic acid bacteria. Lactococcus taiwanensis bacteria have probiotic potential and can produce antibacterial substances.
