Abstract


Kerusakan dan pencemaran lingkungan sebagian besar disebabkan oleh aktivitas manusia berupa limbah industry tekstil, tambang, pertanian, dan perkotaan yang mencemari lingkungan perairan. Nanofiber dipilih dalam penelitian ini karena kemampuannya untuk mengikat ion logam, sedangkan electrospinning digunakan untuk menghasilkan nanofiber dengan sifat adsorpsi yang baik. Proses sintesis dilakukan dengan memvariasikan konsentrasi PVA dan gelatin untuk mendapatkan karakteristik nanofiber NF-IIPs Pb(II). Nanofiber disintesis menggunakan variasi PVA/Gelatin 7/5% wt dan 5/5% wt menggunakan metode electrospinning. Berdasarkan hasil karakterisasi SEM diperoleh rongga terbanyak pada NF-IIPs Pb(II) yaitu variasi PVA/Gelatin 5/5% wt. Hasil ini didukung dengan uji adsorpsi material menggunakan larutan uji 20 ppm dalam 10 mL selanjutnya dikarakteriasi menggunakan AAS dan diperoleh kapasitas adsorpsi pada NF-IIPs Pb(II) yang disintesis menggunakan variasi PVA/Gelatin 5/5% wt dengan jarak jarum 12 cm dan tegangan 12 kV yaitu sebesar 0,33 mg/g. Penelitian ini menyimpulkan bahwa kombinasi Nf-IIPs Pb(II) dengan variasi konsentrasi PVA/gelatin dengan metode electrospinning menghasilkan nanofiber yang efektif untuk mengurangi pencemaran ion Pb(II) di lingkungan perairan.
