Abstract
High concentrations of creatinine and urea in the blood can be removed by dialysis using semipermeable membranes that are selective for certain species and hold other species through diffusion processes. This ability requires a membrane that has an active side, which functions as a targeted species identifier. The membrane must be biocompatible because the membrane will be in direct contact with the body’s biological systems. The membrane material that is made must be acceptable to the blood system so that there is no rejection from the body and have a large contact area to obtain an effective diffusion process. For this reason, a hollow fiber membrane (HFM) is needed. One of the synthetic polymers used as the base material for HFM is PSf. PSf has mechanical strength, heat resistance, and is easily formed into HFM. However, PSf has disadvantages such as lack of active side and less compatible with blood due to its hydrophobic properties. Modification using PEG and chitosan will reduce the hydrophobicity of the PSf. Membrane results were analyzed the physical, chemical, and transportability for urea and creatinine. The results of functional group characterization by FTIR show that the modification reaction was successfully carried out on polysulfone to produce PEG-PSf/CS. The modification succeeded in making the PSf membrane more hydrophilic, as evidenced by a decrease in the contact angle from 69.4° (PSf) to 53° (PEG-PSf/CS). Water uptake capability increases to 609%, and membrane porosity increases porosity increased from 72 to 83%. The water flux is also increased. Creatinine clearance ability increases from 0.09 mg/dl to 0.25 mg/dL. Urea clearance ability increases from 2.3 mg/dL to 3.07 mg/dL. The SEM image showed that the modification makes the membranes more porous.

Abstract
Evaluation character of chitosan membrane-succinate / poly vinyl alcohol-poly ethylene glycol (PVA-PEG) were prepared in acetic acid solvent through a phase inversion method has been performed. The study began with the preparation of crosslinked chitosan compounds with succinic acid, followed by preparation into membrane by combining PVA-PEG. Character analysis of the resulting material using FTIR, EDX, TGA, water absorption test, tensile strength, membrane hydrophilicity. The ability of membrane permeation was tested against creatinine. The results showed that the succinate had reacted with chitosan. Chitosan modification through cross link and polymer alloys increases tensile strength and membrane strain of 1.7-2.5 x of pure chitosan membrane. In addition, the modified membrane also has higher water absorption and hydrophilicity values than the unmodified membrane, and this implies the ability of membrane-induced creatinine permeation. Permeable permeation values were 13.8% in chitosan, 24.84% on chitosan-succinate and 25% in chitosan-succinate / PVA-PEG. Chitosan-succinate membranes have the ability to use more than 4x repeated use.
