Abstract
Hemodialisis merupakan prosedur medis untuk membersihkan darah dari racun dan kelebihan cairan ketika fungsi ginjal mengalami gangguan. Proses hemodialisis menghasilkan produk samping berupa air dialisat sehingga menimbulkan limbah medis yang berbahaya bagi lingkungan. Penelitian ini bertujuan untuk mengetahui potensi penggunaan matriks membran campuran dengan pengisi rGO-Melamin dalam matriks PES untuk menghilangkan urea dan kreatinin pada air dialisat bekas hemodialisis dengan larutan model sintetik. Preparasi pengisi rGO-Melamin menggunakan metode hidrotermal. Fabrikasi membran PES/PVP/rGO-Melamin menggunakan metode non-solvent induced phase solution (NIPS). Material pengisi ditambahlan ke dalam matriks membran dengan variasi konsentrasi 0,05; 0,1; dan 0,3% (b/b%). Berdasarkan hasil XRD, diperoleh sifat dari material rGO-Melamn adalah amorf, dan hasil FTIR menunjukkan adanya gugus fungsional tambahan yaitu -NH2, -OH, dan C=O yang berperan dalam mekanisme pemisahan membran. Penambahan material pengisi rGO-Melamin mampu memfasilitasi adanya ikatan hidrogen dan donor-akseptor elektron terhadap molekul urea dan kreatinin. Peran material pengisi juga membuat membran bersifat lebih hidrofilik daripada membran PES sehingga fluks air juga kian meningkat. Persentase rejeksi urea dan kreatinin optimal dicapai oleh membran PES/PVP/rGO-Melamin 0,1% secara berurutan yaitu 12,75 % dan 60,16%. Hasil optimal juga didapatkan dari hasil fluks urea dan kreatinin yang masih tergolong tinggi yaitu 294.814 L m-2 jam-1 dan 271.818 L m-2 jam-1.

Hemodialysis is a medical procedure to cleanse the blood of toxins and excess fluid when kidney function is impaired. The hemodialysis process produces dialysate water, causing medical waste that is harmful to the environment. This study aims to investigate the potential use of a mixed matrix membrane incorporating rGO-Melamine fillers in a PES matrix for its performance in removing urea and creatinine in dialysate water used for hemodialysis. The rGO-Melamine filler was prepared using the hydrothermal method. The PES/PVP/rGO-Melamine membrane was fabricated using the non-solvent induced phase solution (NIPS) method. The filler material was added to the membrane matrix with concentration variations of 0,05; 0,1; and 0,3% (wt%). Based on XRD results, the properties of the rGO-Melamine material were found to be amorphous, and FTIR results showed the presence of additional functional groups, namely -NH₂, -OH, and C=O, which play a role in the membrane separation mechanism. The addition of rGO-Melamine filler material facilitates hydrogen bonding and electron donor-acceptor interactions with urea and creatinine molecules. The role of the filler material also makes the membrane more hydrophilic than the PES membrane, thereby increasing water flux. Optimal urea and creatinine rejection was achieved by the PES/PVP/rGO-Melamine 0.1% membrane, with values of 12.75% and 60.16%, respectively. Optimal results were also obtained from the urea and creatinine flux values, which remain relatively high at 294,814 L m⁻² h⁻¹ and 271,818 L m⁻² h⁻¹, respectively.
