Abstract
Penelitian mengenai aplikasi teknologi membran untuk desalinasi air telah mengalami perkembangan pesat dalam beberapa tahun terakhir, terutama karena keunggulannya dalam efisiensi pemisahan dan konsumsi energi yang rendah. Pada penelitian ini, komposit ZnO@g-C3N4 disintesis menggunakan metode One Pot Thermal Decomposition. Selanjutnya, ZnO dihilangkan menggunakan metode pelindian asam untuk menghasilkan g-C3N4 (gCN) berpori yang digunakan sebagai material pengisi dalam pembuatan membran matriks campuran (MMM) berbasis PVDF. Keberhasilan sintesis gCN berpori dikonfirmasi melalui karakterisasi XRD, FTIR, dan SEM-EDX. MMM dengan penambahan 0,3 %b gCN berpori (M-0.3) menunjukkan kinerja desalinasi terbaik, dengan fluks air murni sebesar 56,015 L/m2h dan tingkat penolakan garam sebesar 91,304%. Hasil ini mencerminkan peningkatan signifikan dalam kinerja desalinasi dibandingkan dengan membran PVDF murni, dengan peningkatan fluks air murni dan persentase penolakan garam masing-masing sebesar 111,67% dan 31,73%. Penggunaan gCN berpori sebagai material pengisi pada MMMs sangat berpotensi untuk aplikasi desalinasi air yang lebih efisien.

The application of membrane technology for water desalination has advanced rapidly in recent
years due to its low operational energy and high separation efficiency. In this study, the
ZnO@gCN composite was synthesized using a One Pot Thermal Decomposition method.
Subsequently, ZnO was removed using acid leaching method to produce porous gCN, which
was used as a filler material in the fabrication of PVDF-based mixed matrix membranes
(MMMs). The successful synthesis of porous gCN was confirmed by XRD, FTIR, and SEM-
EDX. The mixed matrix membrane with the addition of 0.3 wt% porous gCN (M-0.3) exhibited
the best desalination performance, with a pure water flux of 56.015 L/m²h and a salt rejection
of 91.304%. These results show a significant improvement as compared to neat PVDF
membranes, with increases in pure water flux and salt rejection of 111.67% and 31.73%,
respectively. This finding highlights the potential of using porous gCN as a filler material for
more efficient water desalination applications.
