Abstract
Anion exhange membrane (AEM) merupakan membran bermuatan positif yang dapat menarik dan menampung ion bermuatan negatif atau anion yang kerap digunakan dalam sistem Reverse Electrodialysis (RED) berdampingan dengan Cation Exchange Membrane (CEM) untuk mengekstrak listrik yang berasal dari pencampuran antara air laut dengan air payau yang memiliki gradien salinitas yang berbeda. Dalam penelitian ini berfokus pada fabrikasi dan karakterisasi anion exchange membrane yang bahan dasar polimer polyvinyl alcohol (PVA) dengan variasi komposisi 4 gram, 3,97 gram, dam 3,94 gram, polydiallyldimethylammonium chloride (PDDA) dengan masing-masing sampel 10 ml, filler silika dengan variasi komposisi 0 ml, 0,4 ml, dan 0,8 ml, dan pelarut dimethyl sulfoxide (DMSO) masing-masing sampel 10 ml. Dan penelitian ini bertujuan untuk mengetahui pengaruh dari variasi komposisi polyvinyl alcohol dan filler silika terhadap karakteristik morfologi dalam pengujian Scanning Electron Microscope, karakteristik kimia-fisika dalam pengujian Fourier Transform Infra Red, Area Resistance, Permselectivity, Ion Exchange Capacity, Swelling Degree, dan Fixed Charge Density, dan karakteristik mekanikal dalam pengujian kuat tarik. Hasil analisis pengamatan uji Scanning Electron Microscope menunjukkan dengan penambahan filler silika pada membran AEM menyebabkan terbentukmya pori-pori pada permukaan membran sedangkan pada membran AEM yang tidak diberi filler silika tidak terlihat adanya pori-pori. Untuk metode analisis hasil pengujian membran AEM lainnya menggunakan analisis statistik Analysis of Variance (ANOVA) dan dilanjutkan dengan uji Beda Nyata Terkecil (BNT) 5%. Penambahan variasi komposisi polyvinyl alcohol dan filler silika berpengaruh signifikan pada hasil pengujian Area Resistance dengan nilai area resistance terkecil didapatkan oleh membran AEM SO04 (PVA 4 gram dan filler silika 0,4 ml) yaitu 0,30 kΩ.cm2, kemudian pada uji Permselectivity nilai terbesar didapatkan oleh membran AEM SO08 (PVA 4 gram dan filler silika 0,8 ml) yaitu 51,79%, dan pada uji Ion Exchange Capacity nilai terbesar didapatkan pada membran AEM SO70 (PVA 3,97 gram dan filler silika 0 ml) yaitu 74,54 mmol.g-1 . Sedangkan untuk Swelling Degree, dan Fixed Charge Density variasi komposisi polyvinyl alcohol dan filler silika tidak berpengarih signifikan.
English Abstract
Anion exchange membrane (AEM) is a positively charged membrane that can attract and accommodate negatively charged ions or anions that are often used in Reverse Electrodialysis (RED) systems side by side with Cation Exchange Membrane (CEM) to extract electricity from mixing seawater with brackish water with different salinity gradients. In this study, focus on the fabrication and characterization of anion exchange membranes which are made from polyvinyl alcohol (PVA) with various compositions of 4 grams, 3.97 grams, and 3.94 grams, polydiallyldimethylammonium chloride (PDDA) with each sample of 10 ml, silica as filler with a composition variation of 0 ml, 0.4 ml, and 0.8 ml, and dimethyl sulfoxide (DMSO) as solvent for each sample was 10 ml. And this study aims to determine the effect of variations in the composition of polyvinyl alcohol and silica filler on morphological characteristics in the Scanning Electron Microscope test, chemical-physical characteristics in the Fourier Transform Infra Red test, Area Resistance, Permselectivity, Ion Exchange Capacity, Swelling Degree, and Fixed Charge. Density, and mechanical characteristics in tensile strength testing. The results of the analysis of the Scanning Electron Microscope test showed that the addition of silica filler on the AEM membrane caused the formation of pores on the membrane surface, while the AEM membrane that was not given silica filler did not show any visible pores. For other methods of analyzing the results of AEM membrane testing, statistical analysis of Analysis of Variance (ANOVA) is used and followed by the 5% Least Significant Difference (LSD) test. The addition of variations in the composition of polyvinyl alcohol and silica filler has a significant effect on the results of the Area Resistance test with the smallest area resistance value obtained by the AEM SO04 membrane (PVA 4 grams and silica filler 0.4 ml) which is 0.30 kΩ.cm2, then in the Permselectivity test the value The largest value was obtained by the AEM SO08 membrane (PVA 4 grams and silica filler 0.8 ml) which was 51.79%, and in the Ion Exchange Capacity test the largest value was obtained from the AEM SO70 membrane (PVA 3.97 grams and silica filler 0 ml), namely 74.54 mmol.g-1 . Meanwhile, for Swelling Degree and Fixed Charge Density, variations in the composition of polyvinyl alcohol and silica filler have no significant effect.
