Abstract

Penelitian ini bertujuan untuk menganalisi pengaruh penambahan doping TiO2pada bahan dasar hetero ZnO/SnO2 sebagai sensor gas hidrogen, terhadap karakteristik I-V, nilai sensitivitas, konduktivitas, selektivitas, waktu respon, dan karakterisasi XRD. Metode yang digunakan pada penelitian ini adalah metode solid state reaction berbentuk pelet dimana kalsinasi pada suhu 500°C selama 4 jam, penggerusan, kompaksi, dan proses sintering pada suhu 700°C selama 4 jam. Berdasarkan pengukuran karakteristik I-V diperoleh hasil bahwa bahan ZnO/SnO2 (6% mol TiO2) memiliki sensitivitas tertinggi yaitu 6,06 pada tegangan operasional 12 volt. Nilai selektivitas tertinggi diperoleh pada sampel ZnO/SnO2 (4% mol TiO2) yaitu 1,89 pada tegangan operasional 30 volt. Nilai konduktivitas tertinggi diperoleh pada  sampel ZnO/SnO2 (6% mol TiO2) yaitu 9,81x 10-3 / Ωm  pada lingkungan hidrogen. Sedangkan waktu respon sampel ZnO/SnO2 (8% mol TiO2) pada gas hidrogen yaitu 30 sekon  dan untuk gas oksigen yaitu 36 sekon pada tegangan operasional 12 volt. Dari hasil XRD menujukkan bahwa sampel SnO2  didoping TiO2  mempunyai ukuran kristal lebih besar daripada sampel SnO2 tanpa doping. Campuran SnO2 didoping TiO2 telah terbentuk senyawa baru yaitu Sn2 (TiO4) yang ditandai dengan adanya puncak-puncak baru pada grafik.

Abstract

he ethics of a politician are a necessity to pay attention to in perfecting religious humanism in the world of politics so that it can produce policies that support a prosperous and prosperous society. However, so far what we have encountered has only been limited to campaigning in the stage of gaining the most votes. The speakers related to political ethics, religious ethics, and the relationship between religion and politics have been discussed by figures such as Al Farabi, Ibnu Taymiyah, Miroljub Jevtic, Anthony Gill and others. Therefore, research like this should continue to be carried out so that the results will have a positive impact on politics and our society in the future. Research related to ethics was carried out using library research where the sources were taken from materials that focused on highlighting ethics, politics and religion with a data processing process that went through several stages starting with data coding and ending with drawing conclusions. The results of this research determine that the ethics that must be present in a politician to perfect his religious humanism are related to justice, honesty, responsibility, and broad knowledge which are crucial to the formation of a prosperous and prosperous society which can give birth to a civilization of high value.
