Abstract

Demands for information over the Internet massively increase through the continuous expansion of website applications. Therefore, generating powerful and efficient server architecture for web servers is a must to satisfy Internet users and avoid the overloaded system. The research focuses on developing a new mechanism for load balancing to distribute incoming HTTP requests in website applications by combining the Least Connection algorithm and Multi-Agent System (LC-MAS). The proposed mechanism distributes the request based on load condition and the fewest number of active connections. The research applies virtualization technology to build servers on this proposed mechanism. The architecture is built inside a physical server with Proxmox as virtualization management and Linux Debian 7.11 as an operating system. Then, the research is tested in two scenarios (LCMAS and LC) using 500, 1,000, and 1,500 requests. The performance of this proposed mechanism is measured through the values of average response time, throughput, and error percentage. The results show that the proposed mechanism (LC-MAS) distributes the workload more equally than LC, with an average response time for 1,500 requests of 1338.8 milliseconds, 20.07% error, and 125 transactions per second. The LC-MAS makes the website application performance much better when the request increases. The LC-MAS helps in the utilization of system resources and improves system robustness.

Abstract

Pengelolaan keseimbangan beban server web yang aman dan efisien di era digital saat ini sangat penting untuk menjaga ketersediaan layanan dan ketahanan terhadap ancaman siber. Penelitian ini memfokuskan pada pengoptimalan distribusi beban menggunakan Algoritma Least Connection dalam kerangka Sistem Multi-Agent untuk memperkuat keamanan siber. Simulasi pada penelitian ini melibatkan 1000 hingga 2000 permintaan per detik, Algoritma Least Connection secara konsisten mendistribusikan permintaan dengan mengurangi ketidakseimbangan beban server sebesar 18% dibandingkan metode round-robin. Sistem Multi Agent memantau aktivitas server secara real-time, mendeteksi, dan menanggapi ancaman Distributed Denial of Service (DDoS) dengan menurunkan dampak serangan hingga 35%. Pengujian dilakukan pada tiga server web virtual, dengan hasil yang menunjukkan bahwa pendekatan gabungan ini tidak hanya menyeimbangkan beban server secara efektif tetapi juga memperkuat pertahanan sistem terhadap potensi serangan siber. Penemuan ini mengindikasikan bahwa pendekatan ini dapat secara signifikan meningkatkan kerangka kerja load balancing untuk lingkungan lalu lintas tinggi yang aman.

Abstract

Life Expectancy at Birth (LEB) is a critical indicator of health and well-being, and understanding its variations across regions is essential for effective health policy development. In Central Sulawesi, Indonesia, LEB has shown improvements over recent years. This study aims to explore life expectancy trends in Central Sulawesi from 2022 to 2024 using K-means clustering analysis. The study uses secondary data from the Central Statistics Agency (BPS), focusing on health indicators, education levels, healthcare access, and socio-economic conditions. The results revealed that most districts in Central Sulawesi fall into the high life expectancy category (C3), including urban areas like Palu and Morowali, reflecting better healthcare infrastructure and socio-economic conditions. However, districts such as Parigi Moutong, Tojo Una-Una, and Banggai Kepulauan remain in the lower life expectancy categories (C1 and C2), highlighting significant disparities. These findings underscore the need for targeted interventions to address the healthcare and socio-economic challenges in lower-performing areas. The study concludes that while Central Sulawesi has made progress in improving life expectancy, regional disparities remain. Policymakers should focus on enhancing healthcare access, infrastructure, and education in underdeveloped areas to reduce these gaps on addressing the challenges faced by districts in the C1 and C2 categories.

Abstract

Digital transformation has driven organizations to adopt cloud computing as a flexible and efficient IT infrastructure solution. However, differences between public and private cloud models create challenges in maintaining information security and compliance. This study employs a descriptive–comparative approach through an extensive literature review of journals, conference papers, and standards such as ISO/IEC 27001 and the NIST Cybersecurity Framework (CSF). Findings show that public clouds, while offering cost efficiency and scalability, are more vulnerable to external threats due to limited control and multi-tenancy, whereas private clouds provide stronger governance and customization but demand higher internal resources. The hybrid model emerges as a strategic alternative balancing flexibility and control. Integrating the Confidentiality, Integrity, and Availability (CIA) framework enables a structured evaluation of security risks and governance mechanisms across cloud models. The study highlights that effective governance depends on risk-based policies, compliance alignment, and adaptive controls. It concludes that combining ISO/IEC 27001’s prescriptive management system with NIST CSF’s flexible structure can optimize resilience, compliance, and operational sustainability. This integrated governance approach ensures that cloud security aligns with organizational goals and regulatory requirements while addressing evolving digital risks
