		abstract={Chitosan - Graphene film sensors have been successfully fabrication using
electrodeposition method and cross-linked by glutaraldehyde and sodiun
tripolyphosphate. The effect of addition graphene on chitosan film sensors have
proven improve the sensitivity of chitosan film sensors. Chitosan solution added with
graphene with variation 25 ppm, 50 ppm, 75 ppm, and 100 ppm. The sensing
properties of Chitosan - Graphene film sensors are tested towards urea
concentrations of 1 ppm, 2 ppm, 4 ppm, 6 ppm, and 10 ppm. The measurement results
of maximum voltage from Chitosan - Graphene cross-linked Sodium Tripolyphospat
film sensors (0,647 V) is greater than pure chitosan sensors (0,324 V) and chitosan -
graphene cross-linked glutaldehide (0,6231 V). Based on SEM analysis result
obtained that the Chitosan - Grafene film sensors with an additional 25 ppm
graphene is the best variation, but in sensitivity analysis Chitosan ? Grafene 75 ppm
film sensors showed good sensitivity and reproducibility, and long life time. In this
experiment is also using FT-IR and XRD for characterization.}
