Abstract

Indonesia adalah negara dengan potensi alam yang melimpah, khususnya bahan tambang (mineral), diantaranya material-material dengan kandungan oksida yang mempunyai prospek aplikasi sebagai material cerdas (misalnya SiO2, CaCO3, Al2O3,TiO2, dsb). Tujuan dari penelitian ini adalah mencari atau mengidentifikasi kandungan unsur oksida didalam bahan alam jenis batuan atau pasir kuarsa dengan kemurnian tinggi (> 50%), khususnya sebagai sumber oksida SiO2 (silica) dan CaCO3 (calsite). Selanjutnya bahan-bahan tersebut akan diproses dengan milling proses serbuk (ukuran mikron) untuk, peningkatan kemurnian tinggi dan pengecilan ukuran pada orde nanometer. Identifikasi awal adalah melakukan uji difraksi Sinar-X (XRD) dan analisisnya (kualitatif) serta uji flouresensi sinar-X (XRF). Telah dilakukan uji XRD dan XRF pada sampel batuan yang diambil dari daerah Tulungagung, onik dari pulau Bawean-Gresik, dan pasir dari Tuban dan Sumenep. Hasil difraksi sinar X (XRD) bahan alam (batuan dan pasir) yang diambil sebagai sampel yang diambil dari beberapa daerah tersebut, diperoleh bahwa Batu_1(onik) dan Batu_2(putih) menunjukan bahwa sampel tersebut mempunyai fase dominan struktur kristal Calsite (CaCO3), dan untuk pasir dari Tuban dan Sumenep mempunyai fase dominan quartz (SiO2), demikian. Dan hasil XRF menunjukan kandungan CaCO3 pada sampel batuan (onik) cukup tinggi (98,23%), dan untuk sampel pasir (Tuban dan Sumenep) menunjukan kandungan oksida quartz (SiO2) dengan kemurnian yang tinggi (65,9 -76,8 %), dengan impuritas terbanyak CaO dan Fe2O3 (20-28%).

Abstract

Polysulfones are hydrophobic which can reduce membrane permeability. Permeability can be increased through the application of hydrophilic materials such as GO-Fe3O4 to the polysulfone membrane so that the membrane is hydrophilic. The riset purpose to determine the effect of the percentage weight of different material compositions on the hydrophilicity properties of the polysulfone membrane. Membrane fabrication is carried out using the phase inversion method where the polymer solution is molded in a place and immersed in a coagulation bath containing non-solvent. This solvent exchange causes the polymer to form a solid matrix and become a membrane. The results showed that GO particles were successfully doped with Fe3O4 material shown by XRD analysis at a peak of 35.61˚ with a magnetite phase, while FTIR analysis showed that there was an absorption band characteristic of Fe-O streching vibrations. The results of the contact angle test on the GO-Fe3O4/PSF membrane 0.75 wt per cent were around 73.17˚ which showed the smallest hydrophobic value and the membrane surface morphology had an average pore size of 333.61 nm so that the addition of GO-Fe3O4 composites could increase membrane hydrophilicity.DOI: 10.17977/um024v6i22021p055

Abstract

Polyaniline (PANi) was succesfully prepared from Ammonium Peroxodisulfate (APS) and anyline using chemical oxidation method. Silica (SiO2) was synthesized from natural sands taken from Banjar. PANi/SiO2 composites were prepared using mechanical mixing route. The composites were prepared by variating the weight compositions of PANi:SiO2 of 2.5%, and 5% for SiO2. Furthermore, the coating process of Paint-PANi/SiO2 on SS304 stainless stell by spray coating technique. The characterization of anticorrosive behaviour of Paint-PANi/SiO2 was tested by potentiodynamics method. The obtained Tafel curve was then analyzed by means of ANOVA method. The best anticorrosive performance refered to the sample of Paint-PANi/(5%)SiO2, both of before and after exposure processes. The corrotion rate of before and after exposure processes were 0,00896000 mpy and 0,00024408, respectively. DOI: http://dx.doi.org/10.17977/um024v1i12016p025
