Abstract

A message broker plays a crucial role in distributed communication systems by ensuring reliable message delivery between services. In practice, choosing a message broker involves not only considering performance aspects such as latency and throughput but also security features like authentication, authorization, and encryption. However, challenges arise when enhancing security layers negatively impacts system performance. This study aims to explore and evaluate four popular message brokers—Apache Kafka, Apache Pulsar, Apache RocketMQ, and RabbitMQ—focusing on performance metrics (latency and throughput) across various security configuration levels (no security, TLS, basic authentication, and advanced authentication). The evaluation is conducted through standardized benchmarking processes to assess the impact of security feature implementation on overall system performance. The results of this research are expected to provide insights into the optimal balance between security and performance that remains acceptable by industry standards. Furthermore, the findings may assist developers and system architects in selecting the most suitable message broker configuration based on scalability requirements and data sensitivity levels.

Abstract

This study aimed to develop a mobile application for early skin cancer screening while simultaneously enhancing public awareness of skin health, with a case study conducted in the coastal area of Muara Angke, North Jakarta. The research was motivated by high levels of ultraviolet radiation exposure and limited access to healthcare services, which often lead to delayed skin cancer detection. An empirical quantitative approach was employed by utilizing a Convolutional Neural Network (CNN) based on the ResNet50 architecture, deployed through a cloud based infrastructure and integrated into a Flutter based mobile application. The system was designed using an edge cloud computing approach to address the computational limitations of mobile devices. The results indicated that the application effectively performed preliminary skin lesion screening, provided classification outcomes with confidence scores, and delivered accessible skin health education content. Although the application was not intended to serve as a medical diagnostic tool, it demonstrated significant potential to support early detection efforts and improve community level awareness of skin health. This study contributes to the advancement of mobile health (m-health) by emphasizing the practical implementation of AI based applications tailored to community needs.

Abstract

The transition from secondary to higher education represents a critical phase influenced by both academic readiness and socio-economic conditions. This study proposes a clustering-based approach to identify student support needs during this transition by analyzing multidimensional student profiles. Using secondary data from 1,226 senior high school students, three unsupervised clustering algorithms—K-Means, DBSCAN, and BIRCH—were applied to academic performance and socio-economic variables. Cluster quality was assessed using internal validation metrics, including the Silhouette Score, Davies–Bouldin Index, and Calinski–Harabasz Index. The results indicate that clustering-based methods provide richer insights than traditional rule-based approaches by capturing heterogeneous student profiles and revealing atypical cases. Among the evaluated algorithms, BIRCH demonstrated the most balanced performance in terms of cluster compactness and separation, while K-Means offered stable and interpretable results, and DBSCAN was effective in identifying outliers. Interpreted within the college readiness framework, the identified clusters highlight differentiated student support needs, enabling more targeted and equitable intervention strategies. These findings underscore the potential of educational data mining to support data-driven decision-making in facilitating students’ transition to higher education.

Abstract

This research presents a low-cost automatic Air Conditioner (AC) control system designed to improve energy efficiency and thermal comfort. The system utilizes an ESP 8266 microcontroller, a DHT22 sensor to monitor temperature, and a Passive Infrared (PIR) sensor to detect human presence. It is integrated with the Blynk app for real-time monitoring of temperature and AC status. The system operates based on a control logic that activates the AC only when the room is hot and occupied, adjusting its intensity depending on activity levels. The research follows the prototyping model, using the IRac.h library for managing AC communication protocols. Functional testing in six different scenarios confirms that the system operates effectively, turning the AC on only when needed and shutting it off when the room is empty or the target temperature is reached. The proposed prototype successfully automates conventional AC systems, improving both energy efficiency and user comfort.

Abstract

The skin is a crucial organ in the human body, serving not only as the primary protective barrier but also exhibiting diverse characteristics such as specific types and conditions. Increasingly, people are recognizing the importance of skin care in their daily routines. However, a lack of understanding about different skin types and appropriate skin care products can pose challenges. This research aims to develop a facial skin type classification system based on the existing system. The development of this facial skin type classification system refers to Baumann's Theory, which categorizes skin into four characteristics: Hydration, Sensitivity, Pigmentation, and Aging. The system was developed using the Waterfall methodology and tested using Black Box Testing. The results of Black Box Testing demonstrate that the system functions well and meets the specified requirements. All features and functionalities operate optimally without significant bugs, indicating the success of the Waterfall approach in producing a reliable and ready-to-use system. This system is expected to assist users in accurately identifying their skin type and receiving appropriate skincare solutions, thereby improving the health and appearance of their facial skin.

Abstract

The rapid rise of smart technologies in education has reshaped STEM and coding learning,promoting adaptive and data-driven learning for diverse K-12 students. This study integrates the Technology Acceptance Model (TAM), Task Technology Fit (TTF), and System Usability Scale (SUS) to analyze students’ perceptions of usability, motivation, satisfaction, and learning outcomes. Data were collected from 450 students across elementary, middle, and high school levels to explore variations in digital learning experiences. Clustering analysis using K-Means and Fuzzy C-Means was applied to identify learner profiles based on perception and interaction patterns. The results show that Fuzzy C-Means produced more interpretable and coherent clusters than K-Means, capturing smoother boundaries and overlapping learner characteristics. Three profiles emerged: Young Explorers, Motivated Builders, and Independent Coders, reflecting developmental transitions across educational levels. These findings highlight how clustering approaches can enhance understanding of learner diversity and inform adaptive design in e-learning. The study contributes to personalized learning analytics by linking behavioral perspectives with computational modeling, offering insights for developing inclusive and user-centered digital education systems.
