Abstract

Telah dilakukan sintesis dan karakterisasi sensor liquefied petroleum gas (LPG) berupa pelet dengan bahan utama TiO2 didoping oleh ZnO. Pelet sensor LPG dibuat dengan variasi doping ZnO 0%, 2%, 4%, 6%, 8%, dan 10% terhadap bahan utama TiO2. Proses pembuatan material sensor LPG terdiri dari beberapa langkah yaitu pencampuran bahan, kalsinasi pada temperatur 800ºC selama 4 jam, penggerusan, kompaksi, dan sintering pada temperatur 900ºC selama 4 jam. Sensor LPG diuji pada temperatur ruang (30ºC) dengan melihat karakteristik I-V, nilai sensitivitas, dan nilai konduktivitas. Karakteristik I-V menunjukkan perubahan terbesar terjadi pada sampel TiO2+10% ZnO. Nilai sensitivitas tertinggi dimiliki sampel TiO2+10% ZnO sebesar 10,00 pada tegangan 21 Volt. Nilai konduktivitas tertinggi yaitu 1,8157 Ω-1m-1 pada sampel tanpa doping, lebih tinggi dibandingkan konduktivitas tertinggi sampel yang diberi doping yaitu 0,1045 Ω-1m-1.
