<![CDATA[Kebakaran permukiman merupakan salah satu bencana yang sering menimbulkan kerugian material maupun korban jiwa. Rendahnya pemanfaatan teknologi deteksi dini serta keterbatasan kompetensi masyarakat dalam bidang elektronika dan Internet of Things (IoT) menjadi tantangan dalam upaya mitigasi kebakaran berbasis komunitas. Kegiatan pengabdian kepada masyarakat ini bertujuan meningkatkan kapasitas Karang Taruna Desa Kencana Harapan, Kabupaten Serang, melalui pelatihan perakitan sistem Safety Smart Home berbasis IoT sebagai solusi deteksi dini kebakaran. Metode pelaksanaan menggunakan pendekatan Participatory Action Research (PAR) dan Project-Based Learning (PjBL) yang meliputi tahap persiapan, pelatihan, implementasi, hingga evaluasi. Materi pelatihan mencakup pengenalan komponen elektronika, pemrograman NodeMCU ESP8266, integrasi sensor flame, MQ-2, DHT11, relay, buzzer, pompa air, dan fan, dilanjutkan dengan praktik perakitan, pengujian sistem, dan simulasi penanganan kebakaran. Hasil evaluasi menunjukkan adanya peningkatan kompetensi peserta, dengan nilai rata-rata pre-test sebesar 53,7% meningkat menjadi 88,6% pada post-test (naik 34,9 poin). Sistem yang dikembangkan mampu mendeteksi potensi kebakaran dengan waktu respons rata-rata 1,8–2,4 detik, mengirimkan data secara real-time ke dashboard Thinger.io dengan tingkat keberhasilan pengiriman data 98,3%, serta mengaktifkan alarm dan aktuator secara presisi. Program ini berhasil meningkatkan pengetahuan dan keterampilan peserta serta memperkuat peran Karang Taruna dalam mitigasi kebakaran berbasis teknologi. Residential fires are among the most frequent disasters that can result in significant material losses and casualties. The limited adoption of early fire detection technologies, coupled with insufficient community competencies in electronics and the Internet of Things (IoT), remains a challenge in developing community-based fire mitigation strategies. This community service program aimed to enhance the capacity of the Youth Organization (Karang Taruna) of Kencana Harapan Village, Serang Regency, through training in the assembly of an IoT-based Safety Smart Home system as an early fire detection solution. The implementation method employed a Participatory Action Research (PAR) approach combined with Project-Based Learning (PjBL), consisting of preparation, training, implementation, and evaluation stages. The training materials covered the introduction to electronic components, NodeMCU ESP8266 programming, and the integration of flame, MQ-2, and DHT11 sensors with a relay, buzzer, water pump, and fan. These activities were followed by hands-on system assembly, system testing, and fire emergency response simulations. The evaluation results demonstrated a significant improvement in participants' competencies, with the average pre-test score increasing from 53.7% to 88.6% in the post-test, representing an improvement of 34.9 percentage points. The developed system was capable of detecting potential fire hazards with an average response time of 1.8–2.4 seconds, transmitting data in real time to the Thinger.io dashboard with a data transmission success rate of 98.3%, and activating the alarm and actuators accurately. Overall, the program successfully improved participants' knowledge and practical skills while strengthening the role of Karang Taruna in technology-based community fire mitigation.]]>
