Abstract
Tugas Akhir telah dilakukan dengan tujuan untuk merancang sensor gas karbon monoksida (CO) berbasis interdigital electrode (IDE) dan nanofiber PVA/TiO2, mengetahui respons sensor IDE tanpa nanofiber PVA/TiO2 terhadap gas CO serta mengetahui sensitivitas sensor berbasis IDE dan nanofiber PVA/TiO2 terhadap gas CO. Prinsip yang digunakan yaitu chemiresistor, jika terdapat interaksi antara gas CO dengan nanofiber PVA/TiO2 menghasilkan perubahan resistansi pada sensor. Pembuatan nanofiber PVA/TiO2 dengan menggunakan metode electrospinning. Pada penelitian ini menggunakan variasi konsentrasi TiO2 yaitu 0,1% w/v; 0,2% w/v; 0,3% w/v; 0,4% w/v; dan 0,5% w/v. Sensor IDE dan nanofiber PVA/TiO2 telah menunjukkan prinsip chemiresistor karena dengan bertambahnya kadar gas CO maka resistansi menjadi menurun. Sensor IDE tanpa nanofiber PVA/TiO2 tidak dapat merespons gas CO. Sensitivitas sensor pada kadar gas CO 130 ppm yaitu Sampel A sebesar 5,08; Sampel B sebesar 3,12; Sampel C sebesar 3,75; Sampel D sebesar 3,24; dan Sampel E sebesar 3,53.

This Final Project research has been carried out to design a carbon monoxide (CO) gas sensor based on an interdigital electrode (IDE) and PVA/TiO2 nanofibers, to find out the IDE sensor response to CO without PVA/TiO2, and find the sensitivity of the sensor to CO when using PVA/TiO2. The main principle used is chemiresistance : if there is an interaction between CO and PVA/TiO2, the gas will decrease resistance in the sensor. Preparation of PVA/TiO2 nanofibers are done through the method of electrospinning. This study used variations in the concentration of TiO2, namely 0,1% w/v; 0,2% w/v; 0,3% w/v; 0,4% w/v; and 0,5% w/v. The IDE sensors showed chemiresistance, because with increasing CO levels the resistance decreases. IDE sensors without PVA/TiO2 nanofibers cannot respond to CO. The sensitivity of the sensor variations using CO levels of 130 ppm are : Sample A was 5,08; Sample B was 3,12; Sample C was 3.75; Sample D was 3,24; and Sample E was 3,53.
