Abstract
Alat pemadam api dirancang untuk menghentikan reaksi pembakaran pada suatu area tertentu. Kebakaran merupakan salah satu jenis bencana yang dapat diakibatkan secara alami maupun campur tangan manusia dan sering terjadi di Indonesia. Banyak alat pemadam api yang masih bersifat konvensional, seperti menggunakan air dan zat kimia sebagai bahan dasar yang harus diisi ulang dan memiliki batas waktu kadaluarsa. Metode pemadaman api konvensional tersebut hanya menggunakan sifat-sifat kimia yang tidak ramah lingkungan, bahkan dapat membahayakan proses evakuasi saat terjadinya bencana kebakaran karena dapat menghalangi pengelihatan, merusak barang elektronik, dan mengganggu pernafasan, sehingga diperlukan alat pemadam api berteknologi mutakhir diperlukan sebagai solusi dari permasalahan tersebut. Alat pemadam api berbasis efek vibrasi suara dirancang untuk memadamkan api ringan dan berhasil dibuat dengan 3 komponen utama, yaitu subwoofer dengan collimator vortex tube, box sensor berdimensi 7 cm x 7 cm x 2.5 cm, dan box main controller bedimensi 16 cm x 19 cm x 7 cm. Alat pemadam ini dilengkapi dengan pembangkit sinyal sinusoidal dari digital to analog converter (DAC) pada peripheral STM32. Selain itu, kontrol PID ditanamkan pada mikrokontroller STM32 untuk menentukan amplitudo tegangan peak to peak yang akan masuk ke input amplifier kelas D. Pengujian pemadaman api dilakukan dengan membakar cairan Isoprophyl Alcohol (IPA) didapatkan hasil berupa frekuensi optimal untuk mempersingkat waktu pemadaman pada frekuensi 20 Hz hingga 28 Hz dan kekuatan sinyal audio sebesar 76 dB hingga 124.6 dB dengan waktu pemadaman 1.2 hingga 23.7 detik

Fire extinguisher is designed to stop burning reactions in a certain area. Fire is one type of disaster that can be caused naturally or by human intervention and often occurs in Indonesia. Many fire extinguishers are still conventional, such as using water and chemicals as a base material, which must be refilled and has an expiry date. Conventional fire suppression methods often use chemical properties that are not environmentally friendly, can even endanger the evacuation process during a fire disaster because it can obstruct vision, damage electronic goods, and interfere with breathing. So we need high-tech fire extinguishers as a solution to these problems. Sound vibration based fire extinguishers are designed to extinguish small fires and are successfully made with 3 main components, namely a subwoofer with a collimator vortex tube, a sensor box measuring 7 cm x 7 cm x 2.5 cm, and a main controller box measuring 16 cm x 19 cm x 7 cm. This extinguisher is equipped with sinusoidal signal generator from digital to analog converter (DAC) on STM32 peripherals. In addition, the PID control is embedded in the STM32 microcontroller to determine the amplitudes of peak to peak voltages that will enter the class D amplifier input. The fire extinguishing test is performed by burning Isoprophyl Alcohol (IPA) liquid and the results obtained in the form of optimal frequency to shorten the outage time at a frequency of 20 Hz to 28 Hz and audio signal strength of 76 dB to 124.6 dB with a blackout time of 1.2 to 23.7 seconds
