Tentang Saya (About Me)

Hi, my name is Lelifajri. I have been a lecturer in Departement of Chemistry of Faculty of Mathematics and Basic Sciences of Universitas Syiah Kuala since 2000. I was born and grew up in Banda Aceh. I complated my Bachelor of Chemistry in Departmen of Chemistry Universitas Syiah Kuala in 1995. I finshed my master degree in Departement of Chemistry of Universitas Andalas Padang in 2001. Pendidikan Doktor diperoleh di School of Chemical Sciences Universiti Sains Malaysia pada tahun 2015. Currently, I am incorporated in analytical chemistry peer group at Department of Chemistry. I teache Basic Chemistry, Analytical Chemistry, Environmental Chemistry, Advance Separation, and Chromatography. My researach interest is modification and utilization of biomass and agriculture waste for polutant removal.
