Abstract

The research aimed to identify indigenous yeast antibacterial activity from sapodilla fruit against Escherichia coli and Staphylococcus aureus, which conducted by experimental methods and followed by descriptive analysis. This study was done by the isolation of indigenous yeast, macroscopic and microscopic identification, yeast identification using RapID Yeast Plus System, antibacterial test by measuring the clear zone diameter, testing of pathogenic bacteria viability against indigenous yeast and identification of organic acid produced by yeast. The results of yeast isolation obtained 1 isolate (Saccharomyces cereviseae 1) from fruit and 3 isolates form sapodilla skin (S.cereviseae 2, Candida famata, and Pichia anomala) which had antibacterial activity against E. coli and S. aureus except C. famata isolates. Isolates with the largest antibacterial activity against E. coli and S. aureus based on the clear zone diameter were S. cerevisiae (2) isolates. The results of organic acid analysis by HPLC found that S.cerevisiae (2) isolate produced the highest organic acid namely acetic acid as much as 2.442 mg mL -1.   Key words : antibacterial, organic acid, sapodilla fruit, yeast

Abstract

KPM Internasional is a form of student engagement that integrates academic, social, and cultural dimensions across national boundaries. This study aims to analyze the implementation of the International KPM as a medium for economic and educational diplomacy, using a case study in Hatyai, Thailand. The research employed a qualitative descriptive approach through participatory observation, in-depth interviews, and document analysis. The findings reveal that the KPM program in Hatyai not only strengthens academic collaboration between Indonesian and Thai universities but also creates opportunities for cooperation in the fields of creative economy, local trade, and halal product promotion. Moreover, the program plays a significant role in fostering soft diplomacy through cultural exchange, language interaction, and the dissemination of moderate Islamic values relevant to the Southern Thai context. Therefore, the International KPM serves as an effective instrument for expanding educational and economic networks while enhancing Indonesia’s positive image in the global arena.
