The increasing adoption of artificial intelligence (AI) in decision-making processes has raised significant concerns regarding algorithmic bias and legal accountability. This study examines the regulatory challenges and enforcement gaps in addressing AI bias, with a particular focus on Indonesia’s legal landscape. Through a comparative analysis of AI governance frameworks in the European Union, the United States, China, and Indonesia, this research identifies key deficiencies in Indonesia’s regulatory approach. Unlike the EU’s AI Act, which incorporates risk-based classification and strict compliance measures, Indonesia lacks a dedicated AI legal framework, leading to limited enforcement mechanisms and unclear liability provisions.The findings highlight that transparency mandates alone are insufficient in mitigating algorithmic discrimination, as weak enforcement structures hinder effective regulatory oversight. Furthermore, the study challenges the notion that global AI regulatory harmonization is universally applicable, emphasizing the need for a context-sensitive hybrid model tailored to Indonesia’s socio-legal environment. The research suggests that Indonesia must adopt a comprehensive AI legal framework, strengthen regulatory institutions, and promote interdisciplinary collaboration between legal experts and AI developers. Future research should focus on empirical case studies, the development of context-specific AI accountability models, and the role of public engagement in AI bias mitigation. These efforts will be essential in shaping effective AI governance strategies that ensure fairness, transparency, and accountability in Indonesia’s digital transformation.

I Gusti Ngurah Rai International Airport – Bali is one of the airports with the busiest flight traffic in Indonesia, for both domestic and international routes. The high intensity of operational activities on the airside demands optimal management of all supporting elements, one of which is Ground Support Equipment (GSE). GSE plays a vital role in supporting aircraft movements and handling baggage, cargo, and passengers. Therefore, the provision of well-organized Equipment Parking Area (EPA) facilities in the Make Up and Break Down areas is crucial to ensure smooth and safe operations on the apron. This paper aims to examine the effectiveness of EPA provision and management in supporting GSE work efficiency, while identifying challenges and providing solutions to various emerging problems. The method used is a descriptive qualitative approach through direct observation, field documentation, and analysis of the actual layout compared to the provisions of the Directorate General of Civil Aviation Regulation No. PR 21 of 2023 concerning Technical and Operational Standards for Civil Aviation Safety Regulations. This research also complements EPA management practices at other airports in Indonesia, to provide a constructive comparative perspective. The study results indicate that the current management of the EPA at I Gusti Ngurah Rai Airport is not optimal. The main problems identified include irregular parking of GSE vehicles, the absence of zoning based on vehicle type, minimal markings, and a weak monitoring system due to limited personnel. As a result, congestion often occurs on GSE operational routes, which can disrupt the smooth operation of ground handling services. Based on these findings, proposed improvements include redesigning the EPA layout based on vehicle classification, installing signs and vehicle flow maps in strategic areas, and implementing an integrated technology-based monitoring system such as CCTV and digital access control.

Monkeypox is a zoonotic disease caused by Orthopoxvirus, presenting clinical challenges due to its visual similarity to other dermatological conditions. Early and accurate detection is crucial to prevent further transmission, yet conventional diagnostic methods are often resource-intensive and time-consuming. This study proposes a deep learning-based classification model by integrating Xception and InceptionV3 using feature fusion to enhance performance in classifying Monkeypox skin lesions. Given the limited availability of annotated medical images, data augmentation was applied using Albumentation to improve model generalization. The proposed model was trained and evaluated on the Monkeypox Skin Lesion Dataset (MSLD), achieving 85.96% accuracy, 86.47% precision, 85.25% recall, 78.43% specificity, and an AUC score of 0.8931, outperforming existing methods. Notably, data augmentation significantly improved recall from 81.23% to 85.25%, demonstrating its effectiveness in enhancing sensitivity to positive cases. Ablation studies further validated that augmentation increased overall accuracy from 82.02% to 85.96%, emphasizing its role in improving model robustness. Comparative analysis with other models confirmed the superiority of our approach. This research enhances automated Monkeypox detection, offering a robust and efficient tool for low-resource clinical settings. The findings reinforce the potential of feature fusion and augmentation in improving deep learn-ing-based medical image classification, facilitating more reliable and accessible disease identification.

Human action recognition involves recognizing and classifying actions performed by humans. It has many applications, including sports, healthcare, and surveillance. Challenges such as a limited number of classes of activities and variations within inter and intra-class groups lead to high misclassification rates in some of the intelligent systems developed. Existing studies focused mainly on using public datasets with little focus on real-life action datasets, with limited research on HAR for military obstacle-crossing activities.  This paper focuses on recognizing human actions in an obstacle-crossing competition video sequence where multiple participants are performing different obstacle-crossing activities. This study proposes a feature descriptor approach that combines a Histogram of Oriented Gradient and Region Descriptors (HOGReG) for human action recognition in a military obstacle crossing competition. The dataset was captured during military trainees’ obstacle-crossing exercises at a military training institution to achieve this objective. Images were segmented into background and foreground using a Grabcut-based segmentation algorithm, and thereafter, features were extracted and used for classification. The features were extracted using a Histogram of Oriented Gradient (HOG) and region descriptors from segmented images. The extracted features are presented to a neural network classifier for classification and evaluation. The experimental results recorded 63.8%, 82.6%, and 86.4% recognition accuracies using the region descriptors HOG and HOGReG, respectively. The region descriptor gave a training time of 5.6048 seconds, while HOG and HOGReG reported 32.233 and 31.975 seconds, respectively. The outcome shows how effectively the suggested model performed.

This study analyses the Froude number and type of hydraulic jump in flow through a sluice gate in a secondary channel, both with and without a wide sill. Culverts, as important hydraulic elements in irrigation systems, often trigger hydraulic jumps that have the potential to cause scour. This research is motivated by the need to understand the characteristics of hydraulic jumps in more detail, as a basis for designing effective energy dissipators. Unlike previous studies that focus on contraction coefficient and discharge, this study specifically examines the Froude number and classification of springboard types. This study used secondary data from Sunik's (2001) research which included discharge, water level and flow velocity data for two channel configurations: with and without wide sill. The analysed discharge data varied from 10 to 30 litres/second with variations in door opening. The analytical method used was the calculation of Froude number based on secondary data to classify the type of hydraulic jump. The objectives of this study were to determine the Froude number value and identify the type of hydraulic jump that occurred. The findings showed that discharge and door opening influenced flow characteristics and springboard type. In channels without a sill, discharge affects the transition of flow from subcritical to supercritical. The presence of a wide sill creates a more linear relationship between water level, velocity and Froude number. Varying the door opening affects the type of surge, from choppy, to weak, to vibrating, as the flow energy increases. Larger discharges resulted in higher Froude numbers and stronger surge types. This research makes an important contribution to the understanding of hydraulic springing phenomena and the design of energy dissipator.

Study This contains about the detection of circular object images. The circular object tested is the moon image object, the moon image was chosen because the moon image has various moon shapes, namely the full moon, half moon and crescent moon. To detect the shape of the circular object image, several stages are carried out by starting the image segmentation process. (1) The segmentation process using the bi-level thresholding method makes the image black and white, (2) after that the image is repaired with the morphological process of the opening and closing methods. (3) For training data, the shape extraction process is carried out, namely the circular nature of the object (circularity) to determine the roundness of an object. For the testing process, the same process is also carried out as the process of obtaining circular image detection.

The proliferation of Internet of Things (IoT) devices has introduced significant security challenges, necessitating robust attack detection mechanisms. This study presents a comprehensive comparative analysis of ten supervised learning algorithms for IoT attack detection and classification, addressing the critical challenge of balancing detection accuracy with practical deployment constraints. Using the CICIoT2023 dataset, encompassing data from 105 IoT devices and 33 attack types, we evaluate Naive Bayes, Artificial Neural Networks (ANN), Logistic Regression (LR), k-NN, XGBoost, Random Forest (RF), LightGBM, GRU, LSTM, and CNN algorithms based on some performance metrics. The comparative test results show superior performance to the traditional ensemble approach, with RF achieving 99.29% accuracy and leading precision (82.30%), followed closely by XGBoost with 99.26% accuracy and 79.60% precision. Deep learning approaches also demonstrate strong capabilities, with CNN achieving 98.33% accuracy and 71.18% precision, though these metrics indicate ongoing challenges with class imbalance. The analysis of confusion matrices reveals varying success across different attack types, with some algorithms showing perfect detection rates for certain attacks while struggling with others. The study highlights a crucial distinction in IoT security: while high precision remains important, the potentially catastrophic impact of missed attacks necessitates equal attention to recall metrics, as evidenced by the varying recall rates across algorithms (RF: 72.19%, XGBoost: 71.69%, CNN: 64.72%). These findings provide vital insights for developing balanced, context-aware intrusion detection systems for IoT environments, emphasizing the need to consider performance metrics and practical deployment constraints.
