The Founder's Message

When I first set foot in Germany to study Mechanical Engineering, I was fascinated by the precision and discipline behind every industrial machine. Years later, I returned to Indonesia with one mission: to bring world-class engineering standards to local industries.

As the Founder & Technical Director of PT. Rho Sigma Trijaya, I lead a team dedicated to designing and manufacturing industrial mixing and processing equipment — from High-Speed Dispersers and Ribbon Mixers to Screw Conveyors and Stainless Steel Tanks. Over the past decade, we’ve partnered with global companies to deliver custom-engineered solutions that improve efficiency, safety, and reliability.

Every project I take on is guided by three principles:
🔧 Simplify complexity with practical, efficient solutions
🌍 Support Indonesia’s manufacturing sector with local expertise and global standards
🤝 Build long-term partnerships based on trust and innovation

Our journey began with a simple mission: to deliver reliable, efficient, and proudly Indonesian-made mixing solutions. With a passion for engineering and global industry experience, we remain committed to innovation, quality, and customer satisfaction at the heart of everything we do.
