Feet often produce much sweat, especially when using socks and shoes, which causes bad odor. Three IPB University students who participated in the Student Creativity Program for Research (PKMPE 2019), namely Anita Ervina, Mohammad Rofiqi, and Tiara Fitri Erinanda, tried making a foot odor removal product named Fochi-spray. The research was supervised by Dr. Kustiariyah Tarman.
