Crop drying for cassava farmers
With ASU EPICS and Institut Teknologi Bandung, we designed an affordable hybrid-energy dryer for farmers in Rancakalong, West Java, where rainy-season sun drying can take more than five days and cassava spoils before it sells. I served as Budget Lead, Prototyping Co-Lead, and Software Co-Lead — web server, heating control, and sensor data.
The design takes solar, electric, or biomass heat, regulates temperature and humidity automatically, and uses a desiccant stage to pull moisture out of the air. The prototype hit 60°C and a 50% water reduction in under two days. On site in Bali, Jakarta, and Bandung we visited drying greenhouses, talked with farmers, and ran an international design review against real climate, not a lab assumption.
