Abstract

Penelitian ini bertujuan mengetahui miskonsepsi yang terjadi pada materi larutan penyangga menggunakan instrumen soal two-tier diagnostic test . Instrumen dikembangkan berdasarkan indikator kompetensi materi larutan penyangga menjadi 10 pertanyaan dan dinyatakan valid untuk digunakan. Penelitian dilakukan terhadap siswa dan mahasiswa tingkat I dan III berjumlah 159. Hasil penelitian menunjukkan bahwa terjadi miskonsepsi pada konsep sifat larutan penyangga sebanyak 24,6%, konsep komposisi larutan penyangga sebanyak 24,1%, konsep prinsip kerja larutan penyangga sebanyak 29,3%, dan konsep pH larutan sebanyak 25,4%. Penyebab miskonsepsi dikarenakan konsep awal responden yang lemah, penjelasan guru yang sering menyederhanakan konsep, kebiasaan responden untuk menghafal, pemahaman bahasa dan konsep matematis yang lemah, serta model pembelajaran yang belum memberikan kesempatan responden untuk memahami komponen dan prinsip kerja larutan penyangga secara mikroskopis. Pengetahuan tentang miskonsepsi diperlukan sebagai evaluasi terhadap guru dan dosen agar lebih termotivasi untuk menerapkan model pembelajaran yang mampu mengatasi miskonsepsi untuk mencegah timbulnya miskonsepsi lebih luas dalam pembelajaran kimia yang menjadikan kimia dianggap sulit.

Abstract

This study aims to synthesize thin film of polyaniline-nickel oxide (PANI-NiO) as an electrode in capacitive deionization (CDI) technology. Thin film PANI-NiO were synthesized by electrodeposition method with different applied potentials. The FTIR spectrum and XRD pattern confirmed that PANI-NiO has been successfully synthesized. Based on the SEM-EDX data, PANI-NiO has a tightly stacked granular morphology, which consist of Fe, Cr, S, Ni, O, and C elements. Based on experimental results, the highest capacitance come from PANI-NiO 1.25 V with a value of 475.24 F/g. PANI-NiO 1.25 V also has a small resistance, which is 13.55 Ω. Salt reduction efficiency test for PANI-NiO 1.25 V also shows the highest salt reduction efficiency compared to other electrodes. Owing to its high capacitance, low charge transfer resistance, and high salt reduction capacity, the PANI-NiO prepared at 1.25 V might be a potential material to be developed for the electrolyte deionization application.

Abstract

The research aims to determine the influence of aniline concentration and deposition time on the characteristics of polyaniline prepared using potentiostatic and galvanostatic electrodeposition methods. FTIR characterization data shows the typical peak of polyaniline in the form of the presence of a quinoid functional group at a wavenumber of 1596.16 cm-1. The typical diffraction pattern of polyaniline using XRD was detected at peaks of 2θ 21.1007o and 23.5995o. Polyaniline formed using SEM has a surface morphology that grows in a stacked and irregular manner and has a high conductance value so that it can be used as a substrate in Fe/Ni electrodeposition. The results of the Fe/Ni electrodeposition process when viewed using SEM cause the polyaniline surface morphology to be covered by a Fe/Ni alloy by having an elemental composition from the EDS test data, are iron (Fe) 68.15% and nickel (Ni) 24.83%. Fe/Ni levels from AAS data attached to PANI(pot)-Fe/Ni are 1.1912 ppm and 0.8288 ppm; in PANI(gal)-Fe/Ni are 1.2219 ppm and 0.8392 ppm.

Abstract

In this study, polyaniline was successfully synthesized using an oxidative polymerization method at room temperature. The polymerizations were carried out with and without stirring process under ultraviolet (UV) irradiation. The polyaniline was characterized by FTIR, XRD, SEM, SAA, and Four Point Probe. It is found that UV irradiation and stirring could increase the surface area and conductivity of polyaniline. The surface area obtained for stirred and unstirred polymerization were 37.9 m2/g and 29.0 m2/g, respectively. Moreover, conductivity values for stirred and unstirred polymerization were found as 1.22 S/cm and 1.08 S/cm respectively. This result shows that polyaniline synthesized by stirring treatment obtained uniform morphology, smaller size, greater crystallinity, higher BET surface area, and higher conductivity than that that of without stirring.

Abstract

This research was conducted to determine the effect of solution variations, electrical current, thickness, weight, metal composition, and the characteristics of the Fe-Ni alloy synthesized using the electrodeposition method. The instruments used in this study were atomic absorption spectroscopy (AAS) to determine the metal composition in the deposit, X-ray diffraction to determine the diffraction patterns, and scanning electron microscopy (SEM) to observe morphology and energy dispersive X-ray spectroscopy for elemental analysis. The SEM micrographs obtained showed that morphology of the Fe-Ni alloy was in the form of refined grains. The percentage of Fe in the deposit decreases with the increase in the used current. The AAS data also showed that a high Ni composition in solution will affect the atomic percent of each metal in the deposit. The formation of the alloy was confirmed by diffraction peaks at 2θ of 44°, 53°, and 76° that associated with reflection planes of the face centered cubic structure of Fe-Ni with the crystallite size range from 5 nm to 35 nm.
