Abstract

This study introduces an innovative image encryption algorithm that leverages multiple rounds of matrix scrambling and matrix product transformation. Each round of encryption integrates cross-scrambling operations within the image matrix and invertible matrix product transformations, thereby effectively disrupting pixel positions and values. By iteratively adjusting pixel positions and transforming pixel values, the algorithm significantly enhances the security and robustness of the encryption process. The experimental results demonstrate that the proposed algorithm exhibits excellent resistance to statistical analysis, differential attacks, and other potential threats, thereby ensuring high security and practical applicability.

Abstract

Excessive overtime at PT XYZ is a significant issue for the organization. Besides the significant financial repercussions, they may also affect employee health and productivity. This research aims to forecast future overtime hours, facilitating strategic planning, mitigating excessive overtime, and developing more effective overtime policies. This study employs an overtime realization dataset encompassing many characteristics that influence overtime determinations. The dataset is partitioned into training and testing data to serve as inputs for the three predictive algorithm models: linear regression, artificial neural network, and random forest. The random forest model demonstrates superior performance, evidenced by a mean squared error (MSE) of 158.78, which is proximate to the actual value. The root mean squared error (RMSE) of 12.601 is lower than that of the other two models, indicating a reduced average prediction error. The mean absolute error (MAE) of 8.931 reflects the average deviation from the actual value, while the mean absolute percentage error (MAPE) of 0.336 indicates a prediction error of 34%. Furthermore, the coefficient of determination (R²) of 0.914 signifies that approximately 91.4% of the variation in overtime hours is accounted for, in contrast to the other models, which accounted for 78.8% and 79.6%, respectively. The results indicate that the random forest model demonstrates superior predictive accuracy compared to the other two algorithms, owing to its capacity to handle non-linear data and outliers. Consequently, the random forest model is advocated as the most efficacious method for forecasting the amount of supplementary working hours in the future.

Abstract

Indonesia, as one of the world’s largest archipelagic countries, is highly prone to natural disasters due to its geological, geographical, and socio-demographic conditions. Despite various efforts from the government and related institutions, there remains a lack of an integrated technological solution that addresses the critical aspects of disaster management. This research aims to develop a mobile-based disaster management information system called Aksi Bencana Indonesia, featuring five integrated functions: real-time disaster information, donation facilitation, volunteer management, logistics coordination, and disaster education. The development process involved identifying functional and non-functional requirements through interviews with disaster mitigation experts and literature studies, followed by UI/UX design using Figma, and coding using Flutter for the frontend and Laravel for the backend. User Acceptance Testing (UAT) was conducted with participants aged 18–55 to evaluate the system’s usability and effectiveness. The results showed that the application met the users’ expectations in providing timely and reliable information, facilitating donations and volunteer coordination, and supporting educational initiatives. Moreover, the integration of real-time features improved response time and enhanced the efficiency of resource distribution during disaster events. This study concludes that the application successfully bridges the gap between communities, donors, and volunteers, offering a practical solution for disaster preparedness and response. Future research may focus on expanding the system’s interoperability with national disaster databases and enhancing the analytics dashboard for better decision-making.

Abstract

The increasing frequency of cyberattacks, particularly Denial of Service (DoS) attacks, poses significant challenges to the availability of online services. Multi-target DoS attacks exacerbate this issue by simultaneously targeting multiple systems, requiring robust and automated mitigation strategies. This study evaluates the effectiveness of Wazuh Active Response, an open-source Security Information and Event Management (SIEM) solution, in mitigating multi-target DoS attacks using the Slowloris technique. The methodology involved simulating multi-target DoS attacks using `slowhttptest` against multiple target servers and configuring Wazuh Active Response to automatically block malicious IP addresses upon detection. Key metrics measured included Success Rate, Response Time Detection, and Response Time Blocking. The results showed a Success Rate of 100% with Active Response enabled, an average Response Time Detection of 10.36 seconds, and an average Response Time Blocking of 50.36 seconds. This study confirms that Wazuh Active Response effectively mitigates multi-target DoS attacks, ensuring a high success rate in blocking malicious IP addresses and demonstrating the potential of automated threat detection and response mechanisms in enhancing network security against complex attack scenarios.

Abstract

The resulting digital image certainly has the copyright attached to the image. There needs to be protection of digital image works because the form of storage of digital imagery works that are vulnerable to piracy, claims of unauthorized authorities, illegal duplication, or unauthorized modification. The Spatial Domain Public Image Watermarking method is used to protect digital imagery using applications designed to facilitate the watermarking process on several different digital images as well as with different image formats. The reason for using this method is because it has low complexity. In this study, it consisted of three processes carried out, namely the process of making watermarking, the process of checking watermarking and comparison of input imagery and image results. In the process of making watermarking do image input as a watermarking media, input inserted imagery in the form of binary images / text, key inputs and watermark results. In process of checking watermarking performs image input that becomes watermark media, watermark results input, key input, and checking results. The process of creating watermarking takes a relatively short time while the process of extracting watermarking processing time depends on the size of the image file. From some image testing conducted using imagery with three formats, namely: JPG with an average time accuracy of 9:5,310(42.15%), .GIFs with an average time of 8:27.207(21.63%), and. BMP has an average time accuracy of 5:2.989(36.22%). Thus, the determination of the image format used is adjusted to the original image, so that it can perform time efficiency.
