SEMARANG — A team of Computer Engineering students from the Faculty of Engineering, Universitas Negeri Semarang (FT UNNES), unveiled Trinautom, an autonomous lawnmower robot equipped with smart navigation and precision spraying systems, during the EXPO Capstone held at Building E11, FT UNNES, on Wednesday (November 11, 2026). The prototype introduces a modern, automated approach to lawn and green-space maintenance.
The applied robotics innovation was engineered by four Computer Engineering students: Shaviraj Samad Shaikh, Muhammad Nabel Al Fayyed, Nicodemus Oloan Simanjuntak, and Maulana Fathurahman. The team conceptualized Trinautom to address the inefficiencies of conventional landscape maintenance, which typically relies on labor-intensive manual operation and imprecise liquid application.
By integrating intelligent navigation sensors, Trinautom autonomously maps and executes optimal mowing paths while detecting and avoiding obstacles across yard surfaces. Beyond automated grass cutting, the robot features a precision spraying mechanism engineered to deliver liquid fertilizers, plant nutrients, or targeted treatments directly to specific zones—significantly reducing resource waste and minimizing environmental runoff.
From an engineering and cost-efficiency standpoint, the team completed the prototype on September 3, 2026, following an intensive 97-day cycle of system design, coding, hardware assembly, and field testing. Built with a total budget of IDR 5.5 million (Rp5,500,000), the project demonstrates that sophisticated autonomous robotics can be developed locally at a fraction of the cost of imported commercial alternatives.
During the EXPO Capstone at Building E11, Trinautom drew strong interest from faculty members, fellow students, and visitors observing live demonstrations of the robot’s capabilities. The exhibition serves as a premier showcase for senior engineering students to present real-world technological solutions ready for societal and industrial adoption.
This technological breakthrough directly supports SDG 9 (Industry, Innovation, and Infrastructure) by fostering domestic research, applied automation, and sustainable engineering practices. Through Trinautom, FT UNNES Computer Engineering students highlight the vital role of higher education in driving technological self-reliance, modernizing environmental maintenance workflows, and bridging academic innovation with industry needs.
