A new model has been carried out for fabrication and characterization of silver and copper thin film electrode of IDCs for the measurement of crude oil permittivity. Thin film electrode was fabricated by Direct Current (DC) Magnetron Sputtering method using silver and copper target on Flame Resistant (FR)-4 Printed Circuit Board (PCB). The electrode configuration was composed in seven designs.The experimental results show that, IDCs thin film has a great potential to determine the permittivity of crude oil. © 2018 Elsevier Ltd.

Introduction Crude oil exhibits wide variations in composition and properties, and these variations not only occur in from different fields but also manifested in petroleum taken from different production depths in the same well. Generally, crude oil consists of a complex mixture of various hydrocarbons and some non-hydrocarbon components [1]. One of * Corresponding author. E-mail address: risse15@mhs.physics.its.ac.id
