Daru Widyatmoko's Corner

Thanks for visiting my site!

My name is Iswandaru (Daru) Widyatmoko. I'm a civil engineer. During my professional life, I've been dealing with mostly blacktop, a sticky black hydrocarbon material since my first graduation as a civil engineer in 1992; subsequently I completed my master and doctorate degrees in asphalt materials technology.

Malioboro - Sepanjang Jalan Kenangan

Panas-panas goreng pisang
Kopi agak manis di gelas kaca
Di gelar tikar di terang neon
Di ubun-ubunnya Jogjakarta

Gadis manis senyum-senyum
Tawarkan nasi bungkus daun pisang
Sama-sama makan malam-malam
Di ubun-ubunnya Jogjakarta
