Abstract

Digital archive management in higher education institutions often faces challenges, including document fragmentation, inefficient retrieval, and data loss risks arising from semi-manual processes. This study aims to develop an integrated digital archive system to support personnel services for lecturers at Politeknik Negeri Lhokseumawe. The research employs APKL (Actual, Problematical, Public Concern, Feasibility) and USG (Urgency, Seriousness, Growth) methods for issue prioritization, followed by a Fishbone diagram for root cause analysis. The system was developed using a structured Software Development Life Cycle (SDLC) with a Human Resource Minimum Viable Product (HR MVP) approach. Evaluation via User Acceptance Testing (UAT) yielded an average score of 4.65 (Excellent category), indicating high user acceptance and system effectiveness. The implementation demonstrates that the system significantly improves document management efficiency, ensures data consistency, and accelerates personnel administrative services. This study concludes that the integrated digital archive system provides a robust, adaptive, and practical solution for enhancing administrative quality in higher education environments. Furthermore, the system incorporates intelligent software features, including automated document classification, proactive validation, and efficient search capabilities.

Abstract

Microservices architecture has become the dominant paradigm in modern application development; however, optimal load distribution and resilience against failures remain significant challenges. This study aims to empirically evaluate and compare the performance and fault tolerance of three load balancing strategies (Round Robin, Least Connection, and Weighted Round Robin) under varying load levels and controlled failure injection scenarios in a microservices architecture. The experiment was conducted using a Node.js and NGINX-based e-commerce system under three load levels with three replications per condition. The results show that under normal conditions, all three strategies deliver comparable performance (median difference < 5 ms). Significant differences emerge in tail latency (P99) at high load: Weighted Round Robin records the lowest (292.2 ± 13.7 ms), followed by Least Connection (313.1 ± 54.7 ms) and Round Robin (361.0 ± 67.4 ms). Under dual service failure (50% capacity loss), Round Robin's P99 spikes by 827%, while Least Connection and Weighted Round Robin remain stable (< 1%). Least Connection and Weighted Round Robin are recommended for production systems requiring high fault tolerance.

Abstract

Keamanan jaringan merupakan aspek penting yang harus dijaga untuk memastikan ketersediaan layanan sekaligus melindungi data dari ancaman siber. Salah satu teknik serangan yang sering digunakan adalah port scanning, yaitu upaya penyerang untuk menemukan port terbuka yang dapat dimanfaatkan. Selain itu, serangan Distributed Denial of Service (DDoS) juga kerap digunakan untuk melemahkan atau melumpuhkan layanan dengan membanjiri jaringan menggunakan lalu lintas berlebih. Penelitian ini bertujuan menilai efektivitas Security Onion, sebuah sistem deteksi intrusi berbasis open source, dalam mendeteksi serangan terhadap MikroTik CHR yang terhubung langsung ke jaringan publik. Pengujian dilakukan dengan meluncurkan serangan dari jaringan luar menggunakan perangkat Kali Linux yang menargetkan alamat IP publik MikroTik. Topologi penelitian terdiri atas MikroTik CHR sebagai gateway, Security Onion sebagai sistem pemantauan melalui port mirroring, serta perangkat penyerang dari internet. Hasil pengujian menunjukkan bahwa Security Onion berhasil mendeteksi aktivitas port scanning dan DDoS secara konsisten, dengan tingkat deteksi mencapai 100% berdasarkan perhitungan Attack Detection Rate (ADR). Temuan ini membuktikan bahwa Security Onion mampu memberikan peringatan dini terhadap serangan dari jaringan luar serta berperan penting dalam meningkatkan keamanan jaringan berbasis MikroTik.

Abstract

Penelitian ini dilatar belakangi oleh kebutuhan masyarakat akan sistem otomatisasi rumah yang efisien dan aman dalam mengendalikan perangkat elektronik seperti lampu dan kipas/AC, guna mengurangi pemborosan energi dan meningkatkan kenyamanan. Tujuan dari penelitian ini adalah merancang dan mengimplementasikan sistem smart home berbasis berbasis NodeMCU dan Internet of Things (IoT) yang dapat dikendalikan melalui aplikasi Android dengan memanfaatkan jaringan komunikasi data. Sistem ini menggunakan protokol MQTT untuk mengendalikan perangkat rumah tangga (lampu teras, kipas/AC, dan lampu ruang tamu) dalam tiga mode, yaitu manual, otomatis (timer), dan sensor. Pengujian kinerja dilakukan dengan mengukur delay (latency) menggunakan Wireshark. Hasil penelitian menunjukkan bahwa sistem berfungsi sesuai rancangan dan nilai delay yang diperoleh masih tergolong baik sehingga komunikasi antara aplikasi Android dan NodeMCU berjalan lancar dan responsif.

Abstract

Dikotomi ilmu agama dan ilmu umum masih menjadi persoalan dalam pendidikan Islam, terutama ketika perbedaan bidang keilmuan berkembang menjadi pemisahan dalam sistem pembelajaran dan kelembagaan pendidikan. Penelitian ini bertujuan menganalisis apakah dikotomi tersebut berakar pada epistemologi Islam atau lebih dipengaruhi oleh perkembangan sejarah kelembagaan pendidikan. Penelitian menggunakan pendekatan kualitatif dengan metode studi pustaka (library research) melalui analisis konseptual dan historis terhadap literatur mengenai klasifikasi ilmu, pemikiran tokoh Islam, serta perkembangan lembaga pendidikan. Hasil kajian menunjukkan bahwa pembedaan ‘ulum naqliyyah dan ‘ulum ‘aqliyyah dalam tradisi keilmuan Islam berkaitan dengan perbedaan sumber dan metode memperoleh pengetahuan, bukan dasar bagi pemisahan ilmu secara mutlak. Dikotomi yang berkembang dalam pendidikan modern lebih erat berkaitan dengan faktor historis dan kelembagaan, meliputi kolonialisme, perubahan sistem pendidikan, kebijakan pendidikan, serta pengaruh paradigma sekuler. Namun, cara memahami hubungan antara wahyu, akal, dan pengalaman juga dapat memperkuat pemisahan antardisiplin. Sebagai kontribusi konseptual, penelitian ini mengajukan Proposisi Integrasi Epistemik–Institusional Berlapis (IEIB) yang memadukan orientasi tauhid, keterhubungan sumber dan metode pengetahuan, pembelajaran lintas disiplin berbasis masalah, serta pembaruan tata kelola pendidikan. Penelitian ini menyimpulkan bahwa upaya mengatasi dikotomi memerlukan pembaruan paradigma keilmuan, proses pembelajaran, dan struktur kelembagaan secara terpadu. Proposisi IEIB masih memerlukan pengujian empiris untuk menilai penerapannya dalam praktik pendidikan.

Abstract

Distributed Denial of Service (DDoS) attacks pose a major threat to web server availability, flooding servers with excessive traffic until Legitimate users can no longer reach the service. This study designs an Intrusion Prevention System (IPS) integrating Random Forest-based DDoS detection with iptables hashlimit rate limiting for automatic mitigation on an NGINX web server, reading traffic in real time from access logs rather than raw packet capture; its novelty lies in this end-to-end detection-mitigation integration rather than the individual algorithms. The model was trained on CIC-DDoS2019, mapped to eight deployment-consistent flow features across five classes: BENIGN, Syn, TFTP, DrDoS_UDP, and DrDoS_DNS. Random Forest reached 99.35% accuracy and 0.96 macro F1-score, outperformed Decision tree, SVM, and Logistic Regression baselines, and correctly flagged 99.67% of unseen attack samples as malicious, though BENIGN precision was only 69%. Rate limiting cut packet count by 99.65% (4,938.10 to 17.42 packets per interval) and CPU usage from 28.18% to 11.36%, with detection latency averaging 542.27 ms and iptables execution of just 3.84 ms. Legitimate-user testing showed 100% success rate and zero false positives when Attacker and Legitimate IPs differed, but revealed two limits of IP-based mitigation: shared-IP/NAT users suffered about 103 seconds of disruption from collateral blocking, and concurrent Legitimate traffic near the rate threshold triggered false positives in 5% of intervals. These results show Random Forest combined with iptables-based rate limiting mitigates DDoS effectively while exposing trade-offs between detection accuracy and service availability for real-world deployment.
