Abstract

Pemintalan elektrik (electrospinning) merupakan metode produksi serat yang efektif dan efisien, yang dapat menggunakan berbagai jenis material dan dimanfaatkan untuk beragam aplikasi, salah satunya sebagai media penghantar. Bajakah (Spatholobus littoralis Hassk) merupakan tanaman asli Indonesia yang tinggi akan zat antioksidan dan anti inflamasi. Pada penelitian ini, ekstrak etanolik bajakah diinkorporasikan ke dalam serat selulosa asetat (SA)/gelatin dengan memvariasikan perbandingan volume larutan polimer (SA/gelatin) terhadap larutan ekstrak bajakah (8:1, 6:1, 4:1, dan 2:1). Berdasarkan hasil electrospinning diperoleh bahwa hanya larutan prekursor SA/gelatin 2:1 yang tidak dapat menghasilkan serat. Hasil analisis data karakterisasi SEM menunjukkan bahwa larutan prekursor SA/gelatin dan SA/gelatin/bajakah 8:1, 6:1, 4:1 berturut-turut menghasilkan serat dengan ukuran rata-rata sebesar 1548, 1509, 1377, dan 1079 nm. Uji kadar ekstrak bajakah menggunakan UV-Vis menunjukkan bahwa ekstrak bajakah berhasil diinkorporasikan dalam serat SA/gelatin.

Abstract

Polystyrene (PS) is commonly employed in insulation, packaging, filters, and medical equipment, with recent studies exploring its potential in fiber membrane production. The electrospinning technique is discussed to synthesize PS fiber membranes with high porosity and controllable diameter. Additionally, incorporating silver nitrate into PS composite fibers is explored for enhanced functionalities such as catalytic activity, high electrical conductivity, and antibacterial activity. However, PS composite fiber membranes with silver nitrate (AgNO3) metal variations are rarely observed. This research aims to modify the microstructure of PS fiber membranes produced using electrospinning by adding silver nitrate (AgNO3) with varying concentrations. PS-Ag fiber membranes are produced using N,N-dimethylformamide (DMF) solvent, which serves as a solvent and a reducing agent for Ag. The results show that the effect of Ag affected the diameter of the PS-Ag fiber membrane, with an average diameter of around 3.67 - 6.93 micrometers. Degradation occurred in these samples at a strong broadening peak near ~1300 cm-1 until ~1600 cm-1 from the Raman results. The FTIR results show that the wavelength of ~3500 cm-1 indicated the presence of OH. The presence of OH indicates that the PS-Ag fiber membrane has the potential for water filtration application
