Fertilizer Quality Detection For Purple Sweet Potato Plants Using YOLOv4-Tiny

Fertilizer is a planting medium used to meet the needs of plants to produce well and produce quality results. This study chose fertilizer. It is essential for plants for quality results. In addition, organic fertilizers are not only beneficial for plants. Still, they can also improve land quality for the future and even reduce environmental pollution with the great benefits of fertilizer for plants. It is miserable for purple sweet potato farmers to give the wrong fertilizer to plants because it affects the quality and increases the number of yields. Therefore it is necessary to detect the quality of fertilizer for purple sweet potatoes using the YOLOv4-tiny. The purpose of the research is to make a fertilizer detection system for purple sweet potatoes using YOLOv4-tiny and to analyze the performance of YOLOv4-tiny in detecting the quality of fertilizer for plants. It can be concluded that the fertilizer testing process using the YOLOv4-tiny method obtained a relatively high mAP value, starting with worm manure having an mAP result of 0.69 on grade_a. The worm manure with grade_b has an mAP value of 0.55. Then for mineral fertilizers, in grade_a, it has an mAP value of 0.75. The mineral fertilizers on grade_b have an mAP value of 0.69. The testing process on husk fertilizer, in grade_a, has an mAP result of 0.69, and in grade_b. It has an mAP value of 0.55.
