Abstract

Pemanfaatan model bahasa besar (Large Language Model atau LLM) melalui layanan awan kerap menimbulkan beban biaya dan risiko privasi data. Penelitian ini mengembangkan agen AI lokal berbasis LLM yang terintegrasi dengan N8N, PostgreSQL pgVector, dan Ollama untuk menjawab tantangan tersebut. Sistem yang dirancang bertujuan menciptakan agen AI mandiri yang dapat beroperasi sepenuhnya secara lokal tanpa ketergantungan pada API eksternal. Proses pengembangan melibatkan integrasi orkestrator N8N untuk alur kerja percakapan, penyimpanan memori berbasis vektor melalui pgVector, dan inferensi LLM lokal menggunakan Ollama. Pengujian menggunakan model Mistral:7B menunjukkan bahwa agen mampu menyimpan memori percakapan secara persisten dan melakukan information retrieval yang relevan dengan konteks. Konfigurasi optimal dicapai pada parameter sampling temperature 0,5, top-P 0,9, dan max token 500. Seluruh skenario black-box testing berjalan sesuai rencana. Hasil menunjukkan bahwa prototipe agen AI ini dapat dijalankan secara lokal dengan baik, menjaga privasi data dan tidak bergantung pada penyedia layanan eksternal. Rancangan ini sangat sesuai diterapkan pada organisasi dengan sumber daya terbatas, kebutuhan privasi tinggi, dan skala pengguna kecil hingga menengah.

Abstract

WiFi deauthentication attacks pose a serious threat to users on public WiFi networks by forcibly disconnecting them from access points, often as a prelude to man-in-the-middle exploits. To counter this threat, we developed an energy-efficient ESP32-based IoT system that monitors WiFi traffic in real time to identify deauthentication attack patterns. The device captures deauthentication frames in monitor mode and immediately notifies users through on-device audible/visual alarms (buzzer, LED/OLED) and digital channels (MQTT dashboard and Telegram bot). Experimental evaluation under moderate and high attack scenarios demonstrated robust performance: detection accuracy remained above 97% even under heavy attack traffic (97.8% at peak intensity). Furthermore, the system’s duty-cycled design limited average power consumption to ~79 mA (~30% lower than continuous monitoring) and achieved a rapid notification latency of ~270 ms, confirming real-time responsiveness. By combining physical indicators with online alerts, the system effectively warns users and improves public digital security literacy by making cyber threats immediately visible and understandable. Overall, these results establish the proposed system as a low-power, real-time attack detection solution that enhances WiFi network security and user awareness.
