Abstract

The increasing number of vehicles in urban areas requires technology-based solutions for efficient transportation management. This study proposes a vehicle classification model using Artificial Neural Networks (ANN) with the backpropagation algorithm, based on digital image data. The model is a feedforward neural network comprising an input layer, a hidden layer with 64 sigmoid-activated neurons, and an output layer with 7 softmax-activated neurons. The dataset, sourced from Roboflow Inc., consists of 16,185 images across eight vehicle classes: Hummer, Toyota Innova, Hyundai Creta, Suzuki Swift, Audi, Mahindra Scorpio, Rolls Royce, and Tata Safari. The data is split 80:20 for training and testing. Input features include vehicle dimensions, dominant RGB color, number of axles, and license plate detection. The model is trained using gradient descent and categorical crossentropy loss. Evaluation results show 85% validation accuracy at epoch 28 and 100% test accuracy. Precision, recall, and F1-score indicate strong performance, though minor errors occur in visually similar classes. These findings demonstrate that backpropagation-based ANN is effective for vehicle classification and can be applied in systems such as automatic parking and traffic monitoring

Abstract

Deteksi dini penyakit pada tanaman buah sangat penting untuk menjaga produktivitas dan mutu hortikultura. Keterlambatan mengenali gejala dapat menimbulkan kerugian signifikan, baik dari sisi panen maupun ekonomi petani. Kemajuan machine learning (ML) dan deep learning (DL) menawarkan solusi inovatif melalui diagnosis otomatis berbasis citra daun. Penelitian ini meninjau literatur secara sistematis menggunakan kerangka PRISMA untuk mengkaji dataset, performa model, keterbatasan, tren algoritma, serta arah penelitian selanjutnya. Dari 176 artikel, 50 lolos seleksi, dengan 35 fokus pada penyakit tanaman buah. Hasil kajian menunjukkan bahwa Convolutional Neural Network (CNN) dan variasinya masih mendominasi lebih dari 75% studi. Akurasi model sangat tinggi pada dataset laboratorium (95–99%), menurun pada data lapangan (in-the-wild) seperti PlantDoc (90–96%). PlantVillage tetap menjadi dataset utama, meski uji generalisasi menuntut data lapangan yang lebih beragam. Tantangan meliputi domain shift, class imbalance, keterbatasan label tingkat severitas, serta kendala implementasi di perangkat edge. Kontribusi ilmiah kajian ini berupa rekomendasi riset masa depan diarahkan pada pengembangan dataset lapangan standar, integrasi hybrid CNN–GCN, domain adaptation, data sintetik, segmentasi untuk estimasi severitas, serta Edge AI yang real-time dan dapat dijelaskan (explainable AI). Kajian ini menekankan pentingnya inovasi algoritmik, dataset realistis, dan integrasi IoT/edge untuk sistem diagnosis yang akurat, adaptif,  dan berkelanjutan.

Abstract

This study explores the concept of “Foundations of Jurisprudential Issues” (Uṣūl al-Masāʾil al-Fiqhiyyah) within the Shāfiʿī school, examining its meaning, usage, and practical application through the principle: "Sleep invalidates ablution (wuḍūʾ) except for one sitting firmly". The research problem lies in the ambiguity of this concept and the lack of independent analytical studies, despite its frequent use in Shāfiʿī legal literature. The precise meaning of the term and the methodological approach of the scholars in dealing with it -through derivation (takhrīj) and branching (tafrīʿ)- have not been clearly defined.The study adopts a descriptive, analytical, and comparative methodology, by examining the writings of Shāfiʿī jurists and uṣūl scholars, analyzing their use of the term, and applying it to a specific jurisprudential principle to identify the relied-upon narrations and trace their juristic implications. The main objectives are to define and clarify the concept of Uṣūl al-Masāʾil al-Fiqhiyyah, and to explain the Shāfiʿī methodology in establishing and applying such foundational principles in jurisprudential reasoning. The research concludes that the Foundations of Jurisprudential Issues refer to the authoritative views of Imām al-Shāfiʿī upon which his followers built subsequent rulings. Recognizing these foundations helps in understanding the structure of the madhhab and the criteria of preference within it. The study also finds that the principle "Sleep invalidates ablution except for one sitting firmly" is based on the new (jadīd) opinion of Imām al-Shāfiʿī and has become a firmly established foundation upon which numerous juristic branches are built.
