ABSTRAK REALISASI ALAT UKUR PARTICULATE MATTER (PM10) PADA GAS BUANG KENDARAAN BERMOTOR MENGGUNAKAN INFRAMERAH BERBASIS MIKROKONTROLER ATMEGA32 Oleh YENI PERTIWI Telah dirancang dan direalisasikan alat ukur particulate matter (PM10) menggunakan sensor infrared dengan menampilkan hasil pengukuran pada LCD. Alat ini terdiri atas sensor inframerah,fotodioda, catu daya, mikrokontroler ATMega32, LCD, rangkaian pengkondisian sinyal dan software codevision AVR. Sinar inframerah dipancarkan dan diterima oleh fotodioda. Sinar inframerah yang dikirim akan terhalang oleh objek sehingga menimbulkan perubahan pada tegangan keluaran sensor. Proses pengambilan data PM10 yaitu dengan cara mengukur tegangan keluaran dari kertas GF/A yang telah menampung PM10 dari gas buang kendaraan, dengan waktu 3 menit, 6 menit, dan 9 menit. Pengambilan data PM10 dengan variasi waktu ini menunjukkan peningkatan massa PM10 dan juga menunjukkan keterbatasan kondisi kertas GF/A yang mudah rusak ketika pengambilan data dilakukan lebih dari 9 menit. Sedangkan pada variasi jenis kendaraan tipe 2 tak cenderung lebih tinggi dibandingkan dengan tipe 4 tak dengan perubahan selisih massa antara 0,0020 – 0,0051 gram serta kendaraan berbahan bakar solar lebih tinggi dibandingkan kendaraan berbahan bakar bensin dengan perubahan selisih massa antara 0,0050 – 0,0152 gram. Kata Kunci: Sensor Infrared, PM10, Kertas GF/A, ATmega32, LCD. ABSTRACT REALIZATION MEASURING INSTRUMENT PARTICULATE MATTER (PM10) OF GAS MOTOR VEHICLE WITH INFRARED BASED FROM ON MICROCONTROLLER ATMEGA32 Oleh YENI PERTIWI It has been designed and realizedparticulate matter (PM10) measurementusing an sensors infrared by displaying measurement result in LCD. The device consists of a sensors infrared, photodioda, power supply, microcontroller atmega32, LCD, a series of conditioning the signal and software codevision AVR. Infrared beam emitted and accepted by photodioda. Infrared light sent will be deterred by the object so as to cause changes output voltage. Taking process data PM10 namely by means of measuring an output voltage of paper GF/A that has been accommodate PM10 of the exhaust gases vehicles, with 3 minutes, 6 minutes, and 9 minutes. Taking Process PM10 with the variation of this time show improvement mass PM10 and also demonstrating the limitations the condition of paper GF/A that are easily broken when the data done more than 9 minutes. While upon variations of other kinds of vehicles type 2 Tak tend to be much higher than the type 4 Tak with changes in the difference between 0.0020 to 0.0051 gram and diesel vehicles is higher than gasoline-fueled vehicles to change the mass difference between 0.0050 to 0.0152 grams. Keywords:Infrared Sensor, PM10, Paper GF/A, ATmega32, LCD.
