Bukti Negara: Ancient Martial Art for Modern Needs

Welcome to our school, where the knowledge of Indonesian Martial Arts is preserved, studied, and shared to ensure that the martial science within them is not lost through the centuries.

Our institute focuses specifically on the study of Indonesian styles that possess certain distinctive characteristics:

  • A Direct and Effective Approach
  • Utilization of the body in accordance with the Natural Biomechanics of the human being
  • A Precise and Historically documented Program, yet in tune with the times


These arts exhibit extreme effectiveness in terms of personal defense, combined with exercises that enable the acquisition of impressive mastery in using one’s body, developing explosiveness and flexibility, and enhancing overall health.

Through these transformations, and recognizing the holistic nature of the human being, the practice of these arts allows for improved self-esteem and confidence in everyday life.

We maintain constant connections with schools in Indonesia that share similar approaches to research and delve into our roots. ‘Unity in Diversity’ is the Indonesian national motto, and we draw inspiration from it in our relationships with other schools.

Walter H. van den Broeke: Bridging the Past and Present Starting in 1978, Walter vd Broeke studied with renowned teachers in Indonesia and the Netherlands, now sharing his experience as the Technical Director at the Naga Kuning Institute.

Now, under the guidance of Walter van den Broeke, the torch has been passed to us: we are committed to spreading the art by preserving it in its principles and essence, keeping it up to date with modern training and teaching methods.

All of this is to ensure that our instructors and students can efficiently achieve their goals of personal improvement, both physically and mentally.

A complete Curriculum

Our program consists of 7 Levels, each containing fundamental knowledge for the subsequent ones.

With us, you won’t learn pre-set techniques but will be empowered to create your own applications using the principles of our art and expressing yourself.

You will study empty-hand work, ground techniques, and weapon techniques.

Solo work or against multiple opponents.

Exercises to develop both sensitivity and responsiveness, as well as to become accustomed to impact and conditioning.

Each piece you study will always be correlated with other components of the program, creating a true system that, like a common thread, connects the entire practice.

As you progress in the program, you won’t encounter “more advanced” techniques but principles that solve various problems and shed new light on situations that may have already been addressed in previous levels.

This way, a network is woven among the program’s components, where no exercise is more or less important than others, but all contribute to creating a truly comprehensive training program.
