I am a teacher in SMAN 8 Jakarta, I have been teaching for about 11 years. I joined SMAN 8 winning team since I have graduated from IKIP Jakarta (Now UNJ). Pak Satwiko S, Ph.D (my lecturer in IKIP Jkt) has promoted me to ibu Elida Agus (SMAN 8 principle) to become teacher in SMAN 8. Since June 1997 The story has began. I have experienced many things in this school, things bad and good have passed by me. I also found my soulmate here. Now I have one beloved son, he is 2,5 years old. I finished post graudate program majoring in material science from Universitas Indonesia in 2006. My thesis was Hysteresis Parameter of Jiles-Atherton model identification using Genetic algorithm .
