Abstract

In the digital age, the role of information technology is needed to face competition in the community. Information and communication technology is an important element in contributing to changes that are fundamental to the structure of operations and management of organizations, education, transportation, health, and research. The internet is like two sides of a coin, the content offered is positive and negative, both are very dependent on the behavior of its users. The ease of access to the internet is increasingly being felt by the public with increasingly cheap hardware such as tablets and laptops as well as wider connection support. Various efforts to stem negative information continue to be pursued by various elements of society, but it is not effective if the user behavior is not changed. Teenagers are among the most vulnerable in the misuse of advances in internet technology, so it needs serious efforts to provide the right knowledge and skills in utilizing these advancements. By conducting workshops and motivation to improve the abilities and skills of Girimarto 1 High School students, it is hoped that school students can face the development of the digital era more readily. The results of this training gained a high level of satisfaction with the material that had been carried out.

Abstract

Acute myeloid leukemia (AML) adalah salah satu tipe kanker darah yang mengakibatkan sumsum tulang tidak dapat menghasilkan sel leukosit jenis myeloid yang matang. Pada dasarnya diagnosa penyakit AML menggunakan basis perhitungan jumlah persentase relatif sel leukosit dalam darah. Kesalahan dalam perhitungan jumlah sel dapat berimbas pada kurang tepatnya diagnosa yang dibuat. Dalam pemrosesan citra apusan darah secara digital, salah satu hal yang masih menjadi kendala adalah sel darah yang saling bersinggungan dan bahkan tumpang tindih. Penelitian ini mengusulkan perpaduan algoritma active contour without edge (ACWE) yang dikombinasikan dengan watershed distance transform (WDT) untuk dapat mengatasi permasalahan objek sel darah yang tumpang tindih. ACWE digunakan untuk melakukan segmentasi objek sel darah berbasis perhitungan inside energy dan outside energy sementara WDT diimplementasikan sebagai algoritma pemisah objek dengan memanfaatkan memanfaatkan transformasi jarak dari setiap piksel ke nilai piksel non-zero terdekat. Hasil penelitian menunjukkan dari total 876 objek sel leukosit, terdapat 734 objek yang dapat disegmentasi dengan baik dan sisanya sebanyak 142 objek masih belum dapat diseparasi dengan tepat. Nilai ini menunjukkan bahwa perpaduan algoritma ACWE dan WDT dapat memisahkan 83,789% objek sel leukosit dari citra AML M1, M2 dan M3.

Abstract

Waste has become a serious environmental issue that requires effective and efficient management systems. This study compares three residual network (ResNet) variants (ResNet-34, ResNet-50, and ResNet-101) within the single shot detector (SSD) framework for visual waste detection. The dataset consists of 800 images in four categories—food, plastic, paper, and wood—with a 70:20:10 split for training, validation, and testing. The backbone architecture, optimizer (stochastic gradient descent (SGD) and Adam), and learning rate are varied to evaluate fifteen experimental configurations. Model performance is assessed using precision, recall, F1-score, and mean average precision (mAP). The results show that SSD–ResNet-34 with SGD and a learning rate of 0.0005 works best, with a mAP of 91.02%, which is better than deeper backbones. Deeper backbone architectures do not consistently improve accuracy; instead, they increase the risk of overfitting on small datasets. These findings highlight that lightweight architecture, when used with the right hyperparameter settings, strikes a better balance between accuracy, computational efficiency, and generalization for small-scale waste detection tasks.

Abstract

Rapid population growth contributes to an increase in the volume of vehicles, creating major challenges in their management. One potential solution is the application of deep learning-based artificial intelligence technology for automatic detection of vehicle license plates. This research uses a Systematic Literature Review (SLR) approach to evaluate the performance of various deep learning architectures in the detection process. Out of 125 articles identified, 20 articles were selected based on specific selection criteria. The analysis revealed that preprocessing techniques, such as HE, AHE, ECHE, CLAHE, and ECLACHE, have significant contributions in the processing of vehicle license plate datasets. These techniques were able to improve the visual quality of the images, thus supporting the detection process with an accuracy rate of more than 95%. This research also identified challenges, such as high computational requirements and large-scale data processing. Further research is recommended to apply preprocessing on standardized datasets to develop a reliable, efficient and sustainable detection system.
