<div class="WordSection1"><p><em>Kebakaran gedung adalah peristiwa penyebab kerusakan yang dapat terjadi kapanpun dan tidak dapat diprediksi. Kebakaran mengakibatkan kerugian materi dan korban jiwa. Faktor penyebab kebakaran antara lain korsleting listrik, kebocoran gas dan kelalaian manusia. Selain itu, penanganan lanjutan yaitu dengan bantuan mobil pemadam kebakaran. Namun, masyarakat sering sekali terlambat dalam menghubungi dan memberikan informasi tentang kondisi dan lokasi kepada petugas sehingga menyebabkan api semakin membesar. Oleh karena itu diperlukan suatu alat untuk pengendalian penanganan kebakaran gedung menggunakan sensor suhu, asap dan api dengan aktuator control valve dan buzzer menggunakan fuzzy. Input fuzzy berupa data suhu, asap, api dan outputnya adalah control valve dan buzzer sebagai alarm. Berdasarkan hasil pengujian, sensor suhu memiliki error 0,28% , sensor asap memiliki nilai ADC semakin bertambah apabila terdeteksi asap, sensor api memiliki nilai ADC semakin berkurang apabila terdeteksi api. Control valve aktif secara proporsional sebagai pemadam api berdasarkan suhu, nilai kepekatan asap dan nilai api. Tingkat keberhasilan sistem pengendalian ini adalah 91,7%. </em><em></em></p><p><em>Kata Kunci: kebakaran gedung, api, sensor,sistem pengendalian, fuzzy, aktuator.</em><em></em></p><p> </p><p class="SAP-Affiliation">Control System for Handling Building Fire Using Fuzzy Method</p><p> </p><p><strong>ABSTRACT</strong></p><p><em>Building fire is an event that causes damage that can occur at any time and is unpredictable. Fires cause material loss and loss of life. Factors that cause fire include electrical shortages, gas leakage and human negligence. In addition, further handling is with the help of fire trucks. However, the community is often too late in contacting and providing information about the conditions and location to officers, causing the fire to expand. Therefore, it is needed a tool to control building fire handling using temperature, smoke and fire sensors with control valve and buzzer actuators using fuzzy. Fuzzy input is data of temperature, smoke, fire and output data is the control valve and buzzer as an alarm. Based on the results of the test, the temperature sensor has a 0.28% error, the smoke sensor has an ADC value increasing when smoke is detected, the fire sensor has an ADC value decreasing when the fire is detected. The valve control is proportionally active as a fire extinguisher based on temperature, smoke density value and fire value. The success rate of this control system is 91.7% </em><em></em></p><p><em>Keywords: buliding fire, fire, sensor,control system,  fuzzy, actuator.</em><em></em></p></div><em><br clear="all" /></em>
