Abstract

Telah dilakukan karakterisasi sensor Liquefied Petroleum Gas (LPG) berupa pelet heterokontak dengan lapisan pertama pelet adalah 100% mol CuO dan lapisan kedua pelet adalah CuO yang dicampur 10% mol, 20% mol, 30% mol, 40% mol dan 50% mol TiO2. Tahap pembuatan sensor LPG terdiri atas pencampuran bahan, kalsinasi pada temperatur 500oC selama 4 jam, penggerusan, kompaksi, dan sintering pada temperatur 700oC selama 4 jam.  Sensor LPG diuji pada temperatur ruang (27oC) dengan melihat karakteristik arus dan tegangan (I-V), nilai sensitivitas, nilai konduktivitas dan karakterisasi  XRD. Karakteristik I-V menunjukkan perubahan terbesar terjadi pada sampel CuO/CuO(20% mol TiO2). Nilai sensitivitas tertinggi dimiliki sampel CuO/CuO(20% mol TiO2) sebesar 11,94 pada tegangan 10 volt, dan merupakan sampel yang paling bagus digunakan sebagai sensor gas LPG. Nilai konduktivitas tertinggi dimiliki sampel CuO/CuO(10% mol TiO2) dengan nilai konduktivitas di udara sebesar 6,60557x10-5 Ω-1m-1 dan nilai konduktivitas di LPG 25,80712x10-5 Ω-1m-1.
