A The classification of fruit freshness has significant implications in the food and agriculture industry in Indonesia. Fruit freshness not only affects the quality of the products sold but is also crucial in ensuring consumer safety and reducing food wastage. Non-fresh fruits can become a source of microbial contamination and can cause food poisoning if consumed. Based on these factors, various image processing technologies such as ResNet, DenseNet, MobileNetV2, NASNet, and EfficientNet, CNN, DCNN, etc., have been developed to assist the industry in real-time and efficient classification and detection of fruit freshness. Therefore, this research aims to explore another algorithm, namely YOLOv8, to evaluate the accuracy and precision performance in detecting fruit freshness. In this study, it was found that the YOLOv8 model with 100 epochs and a batch size of 8 yielded a confusion matrix result with an accuracy of 88%. At high confidence levels, the model was able to detect fruit freshness with an average precision of 97%. However, at low confidence levels, the average recall reached 87%. At a balanced confidence level (0.50), the precision and recall F1-Score reached an average of 73%. Evaluation beyond the confidence level showed a precision of 74% and a recall of 75%. These results indicate that the YOLOv8 model has not yet reached an optimal level compared to other algorithms that have an accuracy above 90%. This could possibly be due to the limited number

Pesticides are crucial compounds that farmers require to manage pests attacking plants. However, if the pesticide dosage is misapplied or does not adhere to recommendations, it can harm plants and the environment. Utilizing variable land area implies that the necessary pesticide dosage varies. A prevalent approach for farmers to estimate the required dosage is by roughly using pesticide bottle caps. Due to approximate measurements, there is potential for excessive or insufficient pesticide doses that do not align with recommended limits. Therefore, a system is needed to control pesticide dosages based on the plant area's requirements. This research establishes a system capable of regulate the necessary pesticide dosage, encompassing the volume of pure pesticide and water. The results of this research show that the level of accuracy of pesticide dosage for the required volume of pure pesticide is 97.82%, provided that the minimum system output is 20 ml and above. Meanwhile, the accuracy of pesticide dosage for water volume requirements reached 98.9%. In addition, the system succeeded in controlling the pesticide dose according to recommendations for spraying mustard greens with an overall control accuracy of 97.47%.
