Hello, my name is Hariyanto Subiyantoro, and I have been working at Permata Bangsa School as Head of the Literacy Program and Senior High School Principal since March 2021.

I am originally from Yogyakarta and graduated from Yogyakarta State University in 2015.

I became a teacher because teachers play a vital role in society. They are responsible for educating the next generation of leaders and citizens. By becoming teachers, we can help shape the future of society for the better.

The thing I love about teaching the most is seeing my students learn and grow, and it is also rewarding to know that we are making a difference in their lives.

I believe Permata Bangsa School is the best because it provides a high-quality school that offers students a well-rounded education. The school is committed to academic excellence, character development, and global citizenship.
