Abstract
Kertas mikrofluida multilapis merupakan alat yang dapat memanipulasi fluida melalui kanal berskala mikro (10-9-10-8 L) dengan harga yang terjangkau dan mudah difabrikasi. Pada penelitian ini, kertas mikrofluida multilapis difabrikasi dengan empat variasi substrat kertas dengan lebar kanal bervariasi dan dialiri dengan fluida bervariasi konsentrasi glukosa. Berdasarkan hasil eksperimen terhadap dua kertas hidrofobik dan dua kertas hidrofilik, fluida dengan mudah mengalir pada medium kertas dengan porositas tinggi (46,15%) sedangkan medium kertas dengan porositas rendah (20,18%) aliran fluida melambat baik secara vertikal maupun hozitonal. Selain porositas dan hidrofobisitas, lebar kanal memengaruhi profil aliran kapiler. Semakin lebar kanal maka semakin cepat fluida mengalir. Selain karakteristik substrat kertas, karakteristik fluida juga memengaruhi profil aliran kapiler yaitu viskositas, semakin tinggi nilai viskositas fluida maka fluida mengalir lebih lambat. Berdasarkan fraksi volume pada profil aliran kapiler, kertas terbaik untuk aliran secara vertikal merupakan kertas LF-1 (100% dalam waktu 27 s) dan secara horisontal adalah kertas Whatman grade-1 (100% dalam waktu 0.5 s).

Multilayered microfluidic paper is a device that can manipulate fluids in a micro scale (10-9-10-8L), it is also within an affordable price and easy to fabricate. In this research multilayered microfluidic paper has been fabricated with four different paper substrates with varying channel width, and fluids with varying glucose concentration. Based on the experimental research on two types of hydrophobic paper and hydrophilic paper, the paper with a high porosity of 46,15% allows for the fluid to move easily within the microfluidic device whilst the paper with lower porosity of 20,18% slows down the fluid flow in both the vertical and horizontal flow. Besides the porosity and hydrophobicity of the material, the channel width also plays a role in fluid flow where the wider the channel width the faster the fluid will flow. Other than paper characteristics, the fluid properties itself, i.e. viscosity, affect the fluid flow in a way that the higher viscosity the slower the fluid will flow. Based on the volume fraction from capillary flow the best paper to be used for the vertical flow is LF-1 6 (100% within 27 s) and for the horizontal flow is Whatman Grade-1 (100% within 0.5 s).
