Abstrak telah dilakukan penelitian membran selulosa asetat berbahan dasar limbah tandan kosong kelapa sawit yang dimodifika silika. tujuan pembuatan membran ialah untuk membuktikan kinerja hemodialisis kreatinin. karakterisasi membran dilakukan dengan menggunakan scanning electron microscopy (sem), x-ray diffraction (xrd), differential scanning calorimetry (dsc), thermogravimetric analysis (tga), dan universal testing machine. membran selulosa asetat murni (sa11%-si0%) memiliki derajat pengembangan dan porositas sebesar 38,89% dan 21,23%, sedangkan membran yang dimodifikasi silika 40% (sa11%-si40%) memiliki derajat pengembangan dan porositas yang lebih baik sebesar 41,44% dan 27,81%. membran sa11%-si0% memiliki nilai fluks sebesar 86,86 l/m2 jam, sedangkan membran sa11%-si40% memiliki nilai fluks sebesar 96,25% l/m2 jam. membran sa11%-si0% mengadsorpsi kreatinin sebesar 3,102 mg/g sedangkan membran sa11%-si40% dapat mengadsorpsi sebesar 8,242 mg/g dengan total removal kreatinin masing-masing membran 10,483 mg/g dan 10,062 mg/g. membran termodifikasi silika 40% (sa11%-si40%) memiliki kemampuan yang lebih baik dibandingkan membran murni (sa11%-si0%) dalam proses hemodialisis kreatinin. kata kunci: membran, selulosa asetat, silika, hemodialisis, kreatinin, adsorpsi

ABSTRACT A Research on cellulose acetate membranes made from TKKS modified by silica has been carried out. The purpose of making the membrane is to prove the performance of creatinine hemodialysis. Membrane characterization was carried out using Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), Differential Scanning Calorimetry (DSC), Thermogravimetric Analysis (TGA), and Universal Testing Machine. The pure cellulose acetate membranes (SA11%-Si0%) had swelling and porosity degrees of 38.89% and 21.23%, while 40% silica modified membranes (SA11%-Si40%) had better swelling and the porosity degrees is 41.44% and 27.81%. The SA11%-Si0% membrane had a flux value of 86.86 L/m2 hour, while the SA11%-Si40% membrane had a flux value of 96.25% L/m2 hour. The SA11%-Si0% membrane adsorbed 3.102 mg/g of creatinine while the SA11%-Si40% membrane adsorbed 8.242 mg/g with a total removal of creatinine of 10.483 mg/g and 10.062 mg/g respectively. 40% silica modified membrane (SA11%-Si40%) has better performance than pure membrane (SA11%-Si0%) in creatinine hemodialysis process.
