First than anything Makasih for your answer, and I was checking your profile and I found your post here, I understand you about being a programmer, some time ago I used to program too but I quit. and I must say that your english is good, even the fact that I can find some mistakes you write in a way that is easy to understand, keep writting, the practice helps a lot and worry about the grammar later. here some corrections. 

I am not a writer

I don't know where to start, but i am not a writer. i am just a programmer.
i really hate to write something because i do not know what to write about.
i am looking on the right of this textarea, and i saw a square line with title "Writing ideas".
There are a lot of ideas for me, and i think i will choose one.

wait a minute, i'll read each idea writen inside that square.....

OK. i decided to write about a travel experience.

a few months after my wedding, my wife and I decided to visit my wife big brother in malang ( one city in east java, indonesia ). we started our journey at 8 am ( i forgot the date ), almost 10 minutes in the road we passed a train station and suddenly an idea came my mind. "we have money at least 1.5 million IDR (maybe 1400 USD ) , what if we take 50% of that money to travel to Yogyakarta ( one of state in indonesia near mid java )". and my wife loved that idea. So our journey changed to Yogya.

i don't like to write too much. so just this for today, tomorrow i'll continue.

In general is everything ok, maybe the mistakes are more based about "tenses" but everyone have mistakes in tenses haha don't worry. 

ahhhh jangan lupa !!!! 
tulis "I" in capital, not "i"  maybe it is not so much important about understanding but in grammar it is important.
