Abstract

Cognitive Radio-enabled Long Range Wide Area Networks (CR-LoRaWAN) plays an important role in IoT applications. However, due to the limitations of devices and dynamic scheduling mechanisms of the channels, there is still a challenge to balance energy efficiency against security. This paper proposes two developed algorithms that address these challenges: Algo A and Algo B. Algo A ensures key security by mitigating nonce generation vulnerabilities through the replacement of insecure random numbers with prime numbers. Algo B develops this basis by further improving energy efficiency through optimization in session key generation and device management, adding security to it. Both the algorithms incorporate prime numbers in their session key generation that are verified by the Rabin-Miller test and the Sieve of Eratosthenes, with incorporated solar energy harvesting to give a longer life to such devices. Cognitive radio technology is integrated into it for dynamic and intelligent channel selection. Extensive simulations demonstrate that Algo A is much better at handling data with key security, while Algo B outperforms Algo A on energy consumption reduction by 20% and enhancement of overall network security by 15%. These results reveal that Algo B has a better trade-off between security and energy efficiency; hence, Algo B is more suitable for practical deployment. The work further enhances the sustainability and reliability of CR-LoRaWAN networks, especially in resource-constrained environments.

Abstract

The PA'KEPO (Payo jadi Keluargo Polisi) application is a mobile Android application owned by Polda Sumsel for the recruitment process of police members. This study aims to evaluate user satisfaction and the use of the PA'KEPO application by applying the Unified Theory of Acceptance and Use of Technology (UTAUT) 2 model with the addition of the Perceived Trust variable, which represents users' trust in the security and reliability of the application, enhancing users' intention to use the application and impacting actual usage behavior. The analysis of the relationships between variables employs the Structural Equation Modeling (SEM) approach to test the complex relationships between latent variables, allowing for the analysis of data with diverse scales. The research results indicate that the majority of respondents experienced a high level of satisfaction with the PA'KEPO application. The most influential variables—Effort Expectancy, Perceived Trust, Hedonic Motivation, Habit, and Behavioral Intention—significantly affect Use Behavior. Based on these findings, it is recommended that Polda Sumsel continue to encourage the use of the PA'KEPO application by optimizing the variables that have not yet shown significant effects. Improvement recommendations include evaluating and enhancing the application's functionality in line with the daily needs of its users.

Abstract

The detection of herbal plants plays a crucial role in the utilization of traditional medicine, particularly in the Toba region of Indonesia. This study aims to develop an Android application capable of real-time detection of herbal plants using the YOLOv8 algorithm. The five types of herbal plants targeted in this study are tempuyung, rimbang, papaya leaves, turmeric leaves, and aloe vera. The research methodology includes the collection of a dataset of herbal plant images, which were then labeled using the Roboflow platform. The YOLOv8 model was trained with this dataset to detect herbal plant objects. After training, the model was exported to TensorFlow Lite and integrated into an Android application. Testing was conducted to evaluate the accuracy and real-time detection performance of the application. The results show that the YOLOv8 model achieved a mean Average Precision (mAP) of 92.4%, with optimal real-time detection capabilities on Android devices. The developed application can quickly and accurately detect and identify herbal plants, providing a practical solution for users to recognize herbal plants. This study indicates that the YOLOv8 algorithm is effective for herbal plant recognition applications in a mobile context, opening up opportunities for further development in the integration of AI technology into everyday applications.

Abstract

Air pollution in urban areas is a significant global challenge, and Jakarta is one of Southeast Asia's most polluted major cities. Efforts to address this problem are through the greening of urban areas. The Jakarta Special Region Seed and Plant Protection Development Center (PPBPT) is vital in providing and distributing plant seeds to the community. However, ordering manual seeds is still a significant obstacle to effective and efficient distribution. This research aims to develop a prototype application of Progressive Web Applications (PWA) based seed and seed ordering information system. Using the Extreme Programming (XP) method in this research, the PWA application provides a new perspective to accelerate the handling of urban environmental problems while providing reliable public digital services. The application development cycle with the XP method produces good software with faster turnaround time, lower costs, and responsiveness to user needs. The research results in an information system prototype application with various functions, such as user registration, identity verification, seedling ordering, stock management, and order history. The system proved to automate the seedling ordering process significantly, thus improving stock management efficiency and seedling distribution in 18 gardens under PPBPT. Indirectly, the results of this research support urban greening and contribute to improving air quality in Jakarta. Furthermore, the application can be developed by adding various forms of digital technology to help urban greening in different forms of support or other public service applications.

Abstract

This research evaluates user satisfaction with the e-administration system at the Village-Owned Enterprises (BUMDes) Melung, focusing on identifying features that influence user satisfaction using the Kano model. A survey was conducted with 50 respondents who are active users of the system, analyzing 16 key features, including user registration, online payment, financial transparency, and service reporting. The results indicate that the Online Payment and Financial Transparency features are categorized as "Must-be," meaning these features are considered very important and must function optimally for users to remain satisfied. Meanwhile, the Tour Package Booking and Service Reporting features fall into the "One-dimensional" category, where improvements in the quality of these features directly correlate with increased user satisfaction. These findings suggest that fundamental features supporting reliability and accessibility are top priorities, while optimizing other features can further enhance overall user satisfaction. Development recommendations include improving performance on critical features to ensure a more responsive and efficient e-administration system.

Abstract

This study investigated the factors hindering the successful implementation of online complaints system in tertiary institutions in Northern Ghana, and developed an effective complaint system to enhance service delivery, using iterative waterfall models with CSS, MYSQL, JavaScript, HTML, and visual studio codes. To identify the factors hindering the successful implementation of online complaints system, a structured questionnaire was administered to a sample of 308 participants to ascertain the factors that influence the implementation of online complaints system. The findings revealed that lack of education and training, and inadequate resources are the key factors hindering the implementation of online complaint system. Consequently, a new complaint system was developed from this study which incorporated speech-to-text, and text-to-speech features to cater for the needs of diverse users, unlike the previous ones. This new complaint system was found to be cost effective since students only need access to internet connectivity to lodge complaints, unlike previous ones where students have to travel to school before lodging complaint. Finally, the new complaint system equally efficiently handles students’ complaints by keeping a record of all previously lodged complaints of the user, this particular feature provides educational institutions with insights on the frequency of complaints lodged by users. Based on the results, it is evident that tertiary institutions which are looking forward to adopting and implementing students’ complaints system, should consider educating and training for both staff and students on its usefulness. Also, tertiary institutions are encouraged to adopt and implement this system since it is less frustrating and cost effective.

Abstract

Generation of a 3-dimensional (3D)-based artistic image from a 2-dimensional (2D) image using a generative adversarial network (GAN) framework is challenging. Most existing artistic GAN-based frameworks lack robust algorithms lack suitable 3D data representations that can fit into GAN to produce high-quality 3D artistic images. To produce 3D artistic images from 2D image that considerably improves scalability and visual quality, this research integrates innovative variational autoencoder signed distance function, cycle generative adversarial network (VAE-SDFCycleGAN). The proposed method feeds a single 2D image into the network to produce a mesh-based 3D shape. The network encodes a 2D image of the 3D object into latent representations, and implicit surface representations of 3D images corresponding to those of 2D images are subsequently generated. VAE extracts feature from the two-dimensional input image and reconstructs a voxel-type grid using a signed distance function. Cycle GAN produces improved and high-quality 3D artistic images from 2D images. The publicly available COCO dataset was used to evaluate the proposed advanced 3D-VAE-SDFCycleGAN. The model produced a peak signal noise ratio (PSNR) of 31.35, mean square error (MSE) of 65.32, and structural similarity index measure (SSIM) of 0.772 which indicates the improved quality of the generated images. The results are compared with other traditional GAN methods and the results obtained show that the proposed method outperforms the others in terms of quantitative and qualitative evaluation metrics.

Abstract

The current learning process requires students to be active, creative, and innovative both in activities and lectures. Students are one of the main indicators in the accreditation of a university. Therefore, a tertiary institution is also required to be able to receive and provide assistance to students and graduates in the form of scholarships, such as achievement scholarships. At present, it is quite difficult to determine students who have excelled at tertiary institutions in considering and determining students who are entitled and appropriate to receive them. The Decision Support System is a solution to be able to assist in managing student achievement data and determining the right scholarship recipients, and is supported by blockchain technology so that security is guaranteed and protected so that it is not easily hacked and information can be tracked by parties who are given access, so that they can share information transparently. This study uses the waterfall system development method with the Analytcal Hierarchy Process (AHP) problem solving method for the analysis model of the decision support system , blockchain algorithms, and open source software used solidity ethreum. The actual results will be that a decision support system with the AHP model combined with Blockchain can help provide more precise decisions to determine more appropriate scholarship recipient students, as well as increase trust in parties in tracking every transaction information on student achievement activities transparently and safely.
