Quality Detection of Export Purple Sweet Potatoes Using Yolov4-Tiny

Purple sweet potato is used as a food staple, especially for Indonesian people. The production process for sweet potato has been produced and exported to various countries for market development. One of the businesses that processes sweet potatoes is UBI Jalar UKM in Sukun District, Malang City. Sweet Potato UKM is an agricultural group engaged in the planting of sweet potatoes. Many sweet potatoes sent to the factory were rejected. The process of selecting sweet potatoes for export still uses a manual system by selecting them directly without considering quality.

The results on the detection of sweet potatoes using yolov4-tiny prove that the method detects sweet potatoes according to each grade. Furthermore, the system for detecting the quality of sweet potatoes employs yolov4-tiny technology to ensure that they meet industry standards for export.
