Tempe koro pedang (jack bean tempeh) is a traditional fermented food that is commonly consumed by the people of Yogyakarta, Indonesia. In tempeh fermentation, a variety of microorganism involved in it, including molds, yeasts, and bacteria. The dynamics of the develop microorganisms will affect the physicochemical characteristics and flavor profile of the final product. However, microbial changes during the fermentation process of tempe koro pedang have not been widely studied. Therefore, this study investigates changes in the microbial community during three days of fermentation using a metabarcoding approach through Oxford Nanopore platform. The stages of this research include pH and moisture content measurements, surface observation of tempeh using Scanning Electron Microscopy (SEM), and data analysis of tempe koro pedang samples from Yogyakarta producers. Data analysis includes statistical analysis of pH and moisture content as well as relative abundance analysis and visualization of EPI2ME metabarcoding results data using Rstudio. The results of the study showed a change in the proportion of relative abundance and composition of bacteria and fungal during the fermentation process. The genus Staphylococcus dominated among bacteria, while Rhizopus dominated in fungi. Under SEM, the mycelium of tempe koro pedang appeared more complex and compact and the koro pedang particles became reduced as the fermentation process progressed. The pH value changed significantly (p<0>0.05). These findings are expected to provide preliminary insights into microbial dynamics during tempe koro pedang fermentation, which can be used as a guide for future production optimization and product standardization.
