I completed my bachelor degree (Sarjana) from the Department of Mathematics, Syiah Kuala University in 2000 and earned a master degree in Statistics from Bogor Agricultural University (IPB) in 2005. I have published some scientific articles in statistics at four national journals since 2005 as well as national and international proceedings since 2007. Additionally, I had opportunities to attend and present my research at international conferences in Mathematics and Statistics held in Penang, Kuala Lumpur, Bangkok, Tokyo, Kuala Terengganu, and Pattaya.
