Accurate human detection in video streams with occlusions, illumination variances, and varying distances is crucial for various applications, including surveillance, human-computer interaction, and robotics. This study investigates the performance of two widely used object detection features, Haar-like and Local Binary Pattern (LBP), for detecting human upper bodies in color and depth images. The algorithms are combined with Adaptive Boosting Cascade classifiers to leverage the discriminative power of Haar-like features and LBP texture features. Extensive experiments were conducted on a dataset comprising color images and depth data captured from a Kinect camera to evaluate the algorithms' performance in terms of precision, recall, accuracy, F1-score, and computational efficiency measured in frames per second (fps). The results indicate that when tested on color images, the Haar-Cascade method outperforms LBP-Cascade, achieving higher precision (27.4% vs. 7.8%), recall (49.2% vs. 7.8%), accuracy (21.4% vs. 4.1%), and F1-score (35.2% vs. 7.8%), while maintaining a comparable computational speed (19.07 fps vs. 19.26 fps). However, when applied to depth data, the Haar-Cascade method, coupled with Kalman filtering, demonstrates significantly improved performance, achieving precision (79.3%), recall (79.3%), accuracy (65.8%), and F1-score (79.3%) above 70%, with a computational time of approximately 19.07 fps. The integration of Kalman filtering enhances the robustness and tracking capabilities of the system, making it a promising approach for real-world applications in human detection and monitoring. The findings suggest that depth information provides valuable cues for accurate human detection, enabling the Haar-Cascade algorithm to overcome challenges faced in color image analysis.

Research aims: This study aims to analyze the validity of sale and purchase contracts using Shopee PayLater as a financial technology instrument from the perspective of Islamic law. Design/Methodology/Approach: This research employs a normative juridical approach with a statute-based method. Data were collected from primary legal materials such as fatwas, laws, and regulations, as well as secondary and tertiary legal sources. The study is descriptive in nature. Research findings: The findings reveal that Shopee PayLater does not meet the requirements set by the National Sharia Council of the Indonesian Ulema Council (DSN-MUI) as outlined in Fatwa No. 116/DSN-MUI/IX/2017 concerning Sharia Electronic Money. The feature contains ribawi elements through the imposition of interest (minimum 2.95% per month), a handling fee (1% of the transaction), and a late payment penalty (5% of the total amount), which contradict Islamic principles of fairness and transparency in transactions. Theoretical Contribution/Originality: This research contributes to the ongoing discourse on the intersection of Islamic legal norms and modern financial technology, especially regarding the legal status of Buy Now Pay Later (BNPL) systems in Indonesia. Practitioners/Policy Implications: The findings may serve as a reference for fintech companies, policymakers, and regulators in developing sharia-compliant digital financial products, and encourage re-evaluation of existing BNPL schemes to align with Islamic economic principles. Research Limitations/Implications: This study is limited to the legal analysis based on Indonesian regulations and DSN-MUI fatwas, and does not explore user perspectives or comparative international frameworks. Future research is recommended to include broader empirical and cross-jurisdictional insights.

The purpose of this study was to analyze the influence of Non-Performing Finance (NPF) in moderating the relationship between Third Party Funds, Capital Adequacy Ratio (CAR), and Financing to Deposit Ratio (FDR) to Return on Assets (ROA) at Commercial Banks Sharia in Indonesia for the 2016-2021 period. This research is a type of quantitative research with a correlational approach. By using purposive sampling technique, 8 Commercial Banks Sharia were obtained as research samples. The data analysis technique used to answer the hypothesis in this study uses Moderated Regression Analysis (MRA). The results of the study concluded that partially Third-Party Funds had no effect on ROA, while the CAR and FDR variables partially had an effect on ROA at Islamic Commercial Banks for the 2016-2021 period. Furthermore, when there is the addition of NPF as a moderating variable, the research findings state that NPF is not able to moderate the effect of Third-Party Funds on ROA. Meanwhile, on the other hand, NPF is able to moderate the influence of CAR and FDR on ROA of Islamic Commercial Banks for the 2016-2021 period.

Religious moderation refers to an intermediate grounding in one's approach to religious doctrines. This article was written as an introduction to the topic of the importance of moderation of religious behavior in digital media to encourage moderate and tolerant religious discourse. The digital world presents accessible religious narratives that can be used by relevant parties to resolve conflicts and challenge identity politics, characterized by weakening affiliation with religious organizations, the emergence of religious observers, declining individualism, and the transformation of pluralism. into tribalism. This research is qualitative research using an exploratory descriptive approach. Research results from harmonization of moderation in various domains in the digital space show its momentum. As an Islamic research laboratory, Islamic Religious Universities further modify content through digital media as a means of countering the spread of misinformation through social media. The generally accepted approach is the use of counter-narratives to dissolve the substantial, emotional family tree, i.e. moderate and tolerant.

This study investigates the potential of using Message Passing Interface (MPI) parallelization to enhance the speed of the image stitching process. The image stitching process involves combining multiple images to create a seamless panoramic view. This research explores the potential benefits of segmenting photos into distributed tasks among several identical processor nodes to expedite the stitching process. However, it is crucial to consider that increasing the number of nodes may introduce a trade-off between the speed and quality of the stitching process. The initial experiments were conducted without MPI, resulting in a stitching time of 1506.63 seconds. Subsequently, the researchers employed MPI parallelization on two computer nodes, which reduced the stitching time to 624 seconds. Further improvement was observed when four computer nodes were used, resulting in a stitching time of 346.8 seconds. These findings highlight the potential benefits of MPI parallelization for image stitching tasks. The reduced stitching time achieved through parallelization demonstrates the ability to accelerate the overall stitching process. However, it is essential to carefully consider the trade-off between speed and quality when determining the optimal number of nodes to employ. By effectively distributing the workload across multiple nodes, researchers and practitioners can take advantage of the parallel processing capabilities offered by MPI to expedite image stitching tasks. Future studies could explore additional optimization techniques and evaluate the impact on speed and quality to achieve an optimal balance in real-world applications.
