Membran selulosa asetat yang dimodifikasi dengan karbon aktif telah dibuat dari selulosa asetat berbahan dasar selulosa dari tandan kosong kelapa sawit. Pembuatan membran bertujuan untuk uji hemodialisis kreatinin. Karakterisasi membran dilakukan menggunakan Universal Testing Machine, Differential Scanning Calorimetry (DSC), Thermogravimetrc Analysis (TGA), Scanning Electron Microscope (SEM), dan X-Ray Diffraction (XRD). Membran selulosa asetat murni (membran SA11%-AC0%) memiliki derajat pengembangan dan porositas sebesar 26,15% dan 16,91%, sedangkan membran selulosa asetat yang dimodifikasi karbon aktif 30% loading (membran SA11%-AC30%) memiliki derajat pengembangan dan porositas yang lebih baik yaitu 34,47% dan 22,56%. Membran SA11%-AC0% memiliki nilai fluks sebesar 84,81 L/m2 jam, sedangkan membran SA11%-AC30% memiliki nilai fluks yaitu 90,34 L/m2 jam. Membran SA11%-AC0% mengadsorpsi kreatinin sebesar 0,775 mg/g membran sedangkan membran SA11%-30% mampu mengadsorpsi kreatinin sebesar 2,454 mg/g membran dengan total removal kreatinin masing-masing membran adalah 2,684 mg/g dan 4,076 mg/g membran. Membran SA11%-AC30% memiliki kemampuan yang lebih baik dibandingkan membran SA11%-AC0% dalam proses hemodialisis kreatinin.

Cellulose acetate membrane modified with activated carbon has been made from cellulose acetate based on cellulose from oil palm empty fruit bunches. The purpose of making membranes is to test creatinine hemodialysis. Membrane characterization was carried out using Universal Testing Machine, Differential Scanning Calorimetry (DSC), Thermogravimetric Analysis (TGA), Scanning Electron Microscope (SEM), and X-Ray Diffraction (XRD). Pure cellulose acetate membrane (SA11%-AC0% membrane) has a degree of expansion and porosity of 26.15% and 16.91%, while activated carbon modified cellulose acetate membrane 30% loading (SA11%-AC30% membrane) has a degree of expansion and better porosity, namely 34.47% and 22.56%. The SA11%-AC0% membrane has a flux value of 84.81 L/m2 hour, while the SA11%-AC30% membrane has a flux value of 90.34 L/m2 hour. The SA11%-AC0% membrane was able to adsorb creatinine of 0.775 mg/g membrane while the SA11%-30% membrane was able to adsorb creatinine of 2.454 mg/g membrane with total creatinine removal respectively 2.684 mg/g and 4.076 mg/g membrane. The SA11%-AC30% membrane has a better ability than the SA11%-AC0% membrane in the creatinine hemodialysis process. Keyword: Membrane, cellulose acetate, activated carbon, adsorption and hemodialysis
