Abstract

This study aimed to explore and describe the concept of comparative mathematics in making pecel sauce Blitar. The research method used is an ethnographic method with a qualitative approach. The research subjects are Tlogo Village, Blitar Regency residents, who produce and distribute Blitar's signature pecel sauce. Data collection techniques were carried out by observation, interviews, and documentation with parties related to the manufacture of pecel sauce. The data analysis technique uses the Miles and Huberman flow: data collection, data reduction, data presentation, and decision-making/verification. The validity check in this study used triangulation of data sources. The results showed that there was a concept of proportion in the process of making pecel sauce, including direct proportion (measurement activities of ingredients, time with the number of ingredients, weight of peanuts with the final result of chili pecel, and weight of chili with selling price), and indirect proportion (the number of workers to the duration of manufacture).
