I am trying to write my Essay, but I am not really sure with the grammar. Please anybody help me to correct my Essay. Thanks before.
I wish to continue my study by pursuing magister degree in Material Science and Engineering. I interested in this filed since I was doing my final project for my bachelor degree at The Bandung Institute of Technology, Major in Chemistry. I developed new type of carbon paste electrode for determination of Pb, Cu, and Hg by Square Wave Anodic Stripping Voltammetry (SWASV). To enhance the performance of carbon paste electrode, I modified the surface of electrode by lignin compound. From the measurement of Pb in solution, the modified electrode has better sensitivity 1.6 times than before. The lignin coated on the surface of electrode act as chelating agent that improves the interaction between electrode and metallic ions. Therefore, the accumulation step of metals on the modified electrode is better than before and hence improves the sensitivity of measurement.
After graduated from Bachelors degree, I work as a chemist. My responsibility is developing the formulation of acrylic based polymer as binding agent to be applied in paint, textile, and paper industries. I have developed a dust suppressant polymer based to be applied in coal mining areas located in East Kalimantan, Indonesia. The type of polymer and its composition affect the performance of dust suppressant. The field test results show that the use of polymers as dust suppressant suppresses the formation of dust particles more effectively up to 70% and more durable than water, therefore reducing the frequency of watering that impact on cost efficiency. As a chemist, I have to be able to operate analytical instruments such as, Gas Chromatograph, Atomic Absorption Spectrophotometer, Particle Size Analyzer, and so on. I have to assure the instrument work properly by calibrating and maintaining its performance. Besides that, I have to validate and verify new method before applied for analysis.
I would like to gain a deeper knowledge in Material science and it would be a good chance for me if I get the opportunity to continue my study at XXX Institute of Science and Technology. With my strong foundation in chemistry and my work experience in electrochemistry and polymer, I strongly believe that I will be able to perform my best in pursuing magister degree. By pursuing magister degree in Material Science and Engineering will provide the opportunity for me to raise the research development in my beloved country, Indonesia.
