Abstract

Bandung District is one of crop provider for West Java Province. About 31.158,22 ha is used for crop. However, some of them are not maintained well due to lack of vegetation map information. Local authority has tried to map the vegetation in their area by using free license satellite images, and aerial images from Unmanned Aerial Vehicle (UAV). Despite both images being able to provide large plantation area images, both are unable to classify the vegetation type in those images. Telkom University with Bandung Agriculture Regional Office (Dinas Pertanian Kabupaten Bandung) has conducted joint research to develop algorithm based on 50-layer residual neural network (ResNet50) to classify the vegetation type. The input is of this algorithm is primarily aerial images are captured from different type, height, and position of crops. Seven different ResNet50 configurations have been set and simulated to classify the crop images. The result is the configuration with resized images, employing triangular policy of cyclic learning rate with rate 1.10−7 – 1.10−4 comes out as the best setup with more than 95% accuracy and relatively low loss.

Abstract

Abstrak-Gender seseorang dapat dilihat salah satunya secara visual berdasarkan citra wajah manusia. Selain itu, dengan kemajuan teknologi saat ini, komputer juga dapat melakukan klasifikasi gender berdasarkan data yang dilatih. Proses klasifikasi gender menggunakan komputer dapat diaplikasikan terhadap berbagai sektor seperti industri atau pemerintahan. Pada penelitian sebelumnya, terdapat berbagai metode konvensional yang digunakan untuk melakukan klasifikasi citra, khusus klasifikasi gender berdasarkan citra wajah, namun sebagian besar tidak melakukan Cross-Dataset Evaluation untuk melakukan uji performa terhadap model yang dihasilkan. Tugas akhir ini akan membahas bagaimana melakukan klasifikasi gender berdasarkan citra wajah menggunakan metode Vision Transformer menggunakan dataset AFAD sebagai dataset training dan melakukan Cross-Dataset Evaluation terhadap model yang dihasilkan menggunakan dataset UTKFace. Model yang dibangun berhasilkan mendapatkan akurasi validasi sebesar 0,9676 dan akurasi testing sebesar 0,9661 pada pengujian training atau Same-Dataset serta mendapatkan akurasi 0,8174, Precision 0,8188, Recall 0,8189, dan F1 Score sebesar 0,8189 pada pengujian Cross-Dataset Evaluation.Kata kunci- transformer, vision transformer, gender classification, image processing, computer vision.

Abstract

The general population is concerned with traffic accidents. Driver fatigue is one of the leading causes of car accidents. Several factors, including nighttime driving, sleep deprivation, alcohol consumption, driving on monotonous roads, and drowsy and fatigue-inducing drugs, can contribute to fatigue. This study proposes a facial appearance-based driver fatigue detection system. This is based on the assumption that facial features can be used to identify driver fatigue. We categorize driver conditions into three groups: normal, talking, and yawning. In this study, we used Adaboost to propose Boosting Local Binary Patterns (LBP) to improve the image features of fatigue drivers in the Support Vector Machine (SVM) model. The experimental results indicate that the system's optimal performance achieves an accuracy value of 93.68%, a recall value of 94%, and a precision value of 94%.

Abstract

In the era of globalization and digitalization, mastery of Computational Thinking (CT) has become crucial in computer science education, especially at the junior high school level. This mentoring program is designed to bridge the gap between the evolving curriculum demands and teachers' readiness to implement them, with a specific focus on CT content in the Informatics subject for junior high schools. The activities involve teaching technical aspects of informatics and providing a deep understanding of computational thinking as an essential tool for developing students' analytical, creative, and problem-solving abilities. By enhancing the capabilities of junior high school informatics teachers, this program aims to improve the quality of education and equip teachers with relevant skills to teach CT material to students, thereby contributing to community empowerment through the overall enhancement of digital literacy.
