Inner Wave Pencak Silat (Indonesian: Persatuan Pencak Silat Inti Ombak) is a style developed by my teacher, Guru Daniel Prasetya, which blends Pencak Silat from Madura (a small island neighboring Java to the East) and Central Java.  The name inner wave reflects the duality of these styles high and low, internal and external, physical and mental.


I am an individual with a noble mind and character.

I am a person who honors his fellow man and seeks in silence for friendship and peace.

I am a knight who upholds truth, honesty, and justice; always resilient in facing life’s toughest situations and temptations.

I am a silat player!

To anyone reading this...my thanks and may my comments be helpful to you. I’ve had the great fortune of knowing Guru (Charles) for almost 3 years. I have enjoyed sports for a good part of my life, my favorites being wrestling and football. I’d love to write about my accomplishments in both but this is obviously not about me. Saying that, I can pin someone to the floor but I was unable to defend myself if I ever found myself needing to. Though I have much to learn and a way to go, I’m confident in what I’ve learned. I don’t have an extensive martial arts background so, having researched many arts, I’ve found Silat to be not only my favorite but the most practical in real life situations. Guru Charles, is a fantastic instructor, his patience, honestly makes you feel like a student and not a number having to graduate in a time frame set against a learning curve. Simply you get what you put into it with Sifu guiding your path to get there. My best and my we see you in our classes.
