Abstract

The talking stick learning model is a learning model that allows students to be active and creative so that Students cognitive learning outcomes can be achieved. This learning model basically uses the help of a stick, but in practice it can be combined with appropriate learning media. In this case, the researcher only used the stick as a test of the talking stick learning model on Studentscognitive learning outcomes. The method of testing this model used a quasi-experimental design with a One-group pretest-posttest design with 3 trials. The results of the research proved that the second (71.56) and third (78.44) experiments have reached the KKM (> 70). This proves that the talking stick learning model can improve Students cognitive biology learning outcomes.

Abstract

This community service initiative aims to enhance awareness and skills among the local population in Tawangmangu Subdistrict, Karanganyar Regency, Central Java, Indonesia, in utilizing banana peel waste as a raw material for high-value economic products. As the leading banana-producing area in the regency, contributing tens of thousands of quintals in 2024 (Badan Pusat Statistik Kabupaten Karanganyar, 2025; Pantura Post, 2025a), Tawangmangu faces significant challenges in managing organic waste that poses risks of environmental pollution. Employing an entrepreneurship-based approach, the program trained participants to process banana peels into liquid organic fertilizer (POC), jam, and healthy snacks such as pudding and crackers, thereby promoting circular economy principles and zero-waste practices. Results demonstrated a 75% increase in participants’ knowledge and the potential for additional income through the sale of processed products. This activity contributes to sustainable development in the Tawangmangu tourism area.
