Abstract

The ripeness level of bananas is a crucial factor that affects the quality, taste, and selling value of the commodity, but the manual sorting process that is commonly carried out is still subjective, inconsistent, and time-consuming. This study aims to implement and evaluate the performance of a VGG16-based Convolutional Neural Network (CNN) architecture in automatically classifying the ripeness level of bananas. The research dataset consists of 5,616 digital images obtained from the Roboflow Universe platform and grouped into six specific classes: freshripe, freshunripe, overripe, ripe, rotten, and unripe. The system development methodology includes data division using stratified splitting techniques, image pre-processing with data augmentation strategies to prevent overfitting, and the application of transfer learning. The model was trained using the Stochastic Gradient Descent (SGD) optimization algorithm with a learning rate of 0.001 for 25 epochs on GPU-based hardware. Performance evaluation was conducted in depth using a confusion matrix, F1-Score metrics, and Precision-Recall curve analysis. The experimental results showed that the VGG16 model achieved an overall accuracy of 97.13%. Class-by-class analysis shows perfect performance in the freshunripe category, although there is a slight decrease in precision in the ripe class due to the similarity of visual characteristics with the overripe class. The stability of the training and validation accuracy curves also indicates that the model has good generalization capabilities. This study concludes that the VGG16 architecture is a reliable and accurate solution to support the efficiency of smart farming systems.

Abstract

Mosque management in Indonesia is still largely carried out manually and conventionally, resulting in inefficiencies in information dissemination, activity recording, and financial transparency. The development of generative artificial intelligence enables the acceleration of designing more effective and user-friendly e-mosque application interfaces. This community service activity aims to enhance the knowledge and skills of mosque administrators and youth of the Majelis Pemuda dan Remaja Islam (MADARIS) Jakarta Islamic Center (JIC) through mosque digitalization. Community training for mosque youth was conducted with the topic of designing mosque management mobile applications using generative AI technology. The output of this community service activity produced user-friendly UI/UX designs that meet community needs. The training was held offline at the Nusa Mandiri Margonda Campus on May 9, 2026. Evaluation results showed that 64% of participants agreed and 36% strongly agreed that this activity broadened their insights. Meanwhile, 55% of participants agreed and 45% strongly agreed that this activity enhanced their skills. The achievement of this activity is that participants gained knowledge on how to utilize generative AI to design UI/UX and acquired practical skills in creating e-mosque application prototypes to support mosque digitalization.
