Abstract

Passiflora edulis Sims (purple passion fruit) is a fruit that offers numerous health benefits and possesses high economic value. However, the manual assessment of ripeness by traders tends to be subjective and inconsistent, leading to post-harvest losses of up to 50%. This study developed a classification model for determining the ripeness level of purple passion fruit using a Convolutional Neural Network (CNN) and implemented it in a web-based application. The CNN model was designed to classify four ripeness stages (unripe, half-ripe, ripe, and rotten) with the addition of a non-passion-fruit class to enhance the system’s robustness. The dataset consisted of 2,000 images divided into five classes: four ripeness levels of purple passion fruit (unripe, half-ripe, ripe, and rotten) and one non-passion-fruit class as a comparator. All images were in JPG and PNG formats. The CNN architecture comprised four convolutional layers with 16, 32, 64, and 128 filters, respectively. Evaluation of various data-splitting ratios (80:20, 70:30, 60:40) and learning rates (0.001, 0.0001, 0.01) showed that the optimal configuration was achieved at a ratio of 80:20 with a learning rate of 0.001, resulting in a training accuracy of 96.72% and a testing accuracy of 95.76%, with a loss value of 0.1811. Validation using 5-Fold Cross Validation produced an average accuracy of 95.40%. The model was integrated into a web application developed using Flask and JavaScript, deployed on the PythonAnywhere cloud platform, enabling users to upload images and automatically obtain ripeness predictions to assist traders in sorting fruits more quickly and accurately.

Abstract

Communication is an essential human right, yet a significant communication gap persists between individuals with sensory disabilities, specifically the deaf and speech-impaired, and the general public. While many technological solutions have been proposed to translate sign language, existing models primarily rely on heavy deep learning architectures such as Convolutional Neural Networks (CNN) or Recurrent Neural Networks (RNN/LSTM). These models often demand high computational power, leading to latency and limiting real-time application on standard devices. This study proposes a lightweight, fast, and highly responsive sign language translation system specifically designed to recognize static alphabets (A-Z) and single-character air writing. The system utilizes MediaPipe for hand tracking, where feature extraction is intelligently processed by calculating the relative spatial coordinates of fingertips to the wrist, reducing dependency on raw camera coordinates. Classification is performed using a Support Vector Machine (SVM) with a Radial Basis Function (RBF) kernel, prioritizing computational efficiency without sacrificing accuracy. To enhance user experience, the system introduces three key novelties: smart relative feature extraction, an anti-duplication hold system with a 1-second timer to prevent input spamming, and a non-blocking multithreaded audio execution (Daemon Thread) utilizing Google Text-to-Speech (gTTS), ensuring the webcam feed remains fluid during audio playback. Additionally, an alternative air-writing mode is integrated, utilizing geometric heuristics and PyTesseract OCR to read single drawn letters in the air. The results indicate that the proposed system operates swiftly and efficiently, bridging the communication barrier with a hardware-friendly approach.

Deteksi dini sangat penting karena gejala awal sering tidak dikenali atau diabaikan. Penelitian ini mengusulkan sistem deteksi dini depresi berbasis kecerdasan buatan melalui analisis citra wajah menggunakan pendekatan hibrida Convolutional Neural Network (CNN). Data diperoleh dari rekaman wawancara klinis pasien dengan diagnosis depresi dan individu normal. Ekstraksi fitur dilakukan menggunakan tiga arsitektur CNN, yaitu VGG16, ResNet101V2, dan MobileNetV3, yang kemudian digabungkan untuk membentuk representasi fitur gabungan. Selanjutnya, algoritma Random Forest digunakan sebagai klasifikator. Hasil eksperimen menunjukkan bahwa kombinasi VGG16 dan MobileNetV3 memberikan performa terbaik dengan akurasi 94.55%, presisi 98.04%, dan spesifisitas 98.18%. Temuan ini menunjukkan bahwa pendekatan hibrida CNN dengan Random Forest berpotensi menjadi metode efektif untuk mendukung deteksi dini depresi berbasis citra wajah.   Abstract Depression is a major mental health disorder and one of the leading causes of disability worldwide. Early detection is crucial since initial symptoms are often overlooked or unrecognized. This study proposes an artificial intelligence–based early detection system for depression through facial image analysis using a hybrid Convolutional Neural Network (CNN) approach. Facial data were obtained from clinical interview recordings of patients diagnosed with depression and healthy individuals. Feature extraction was carried out using three CNN architectures VGG16, ResNet101V2, and MobileNetV3 whose features were then combined into a joint representation. A Random Forest algorithm was employed for classification. Experimental results indicate that the hybrid model combining VGG16 and MobileNetV3 achieved the best performance, with 94.55% accuracy, 98.04% precision, and 98.18% specificity. These findings demonstrate that the proposed CNN Random Forest hybrid approach is a promising method for supporting early depression detection based on facial features.

Abstract

The management of waste in Indonesia is currently suboptimal, with only 66.24% being effectively managed, leaving 33.76% unmanaged. This highlights a significant challenge in waste management, primarily due to a lack of understanding in selecting appropriate waste types. Advances in deep learning and computer vision offer promising solutions to this issue. This study employs the YOLOv8l model, a well-regarded deep learning model for object detection, to develop an automated waste type detection system integrated with trash bins. The dataset comprises 2800 images across four classes, each containing 700 images, and is split with an 80:10:5 ratio for training, validation, and testing. Evaluation on test data yields a mean Average Precision (mAP) of 96.8%, indicating robust model performance in object detection. The model's accuracy is further validated with a score of 89.98%. Real-time testing conducted at Merdeka Park, Binjai, demonstrates the system's capability to detect waste with varying confidence levels, consistently above the 0.5 threshold. The highest confidence was observed in bottle detection at 0.94, and the lowest in cans at 0.64, underscoring the system's reliability across different detection scenarios within a 30cm range.
