Abstract

This activity aims to Increase the Motivation and Science Literacy of SMP IT Khairu Ummah Rejang Lebong Students. This activity is one form of implementing the tridharma of higher education. One of the tri dharmas of higher education is community service, this service activity is an activity that every lecturer must carry out, therefore lecturers in the Master of Science program at Bengkulu University collaborated with IT SMP teacher Khairu Ummah Rejang Lebong Bengkulu on September 28, 2024, to carry out service activities at SMP IT Khairu Ummah Rejang Lebong. This collaboration takes the form of community service activities at SMP IT Khairu Ummah Rejang Lebong Bengkulu with the title "Robotics Workshop to Increase Motivation and Science Literacy of SMP IT Khairu Ummah Rejang Lebong Students". From these activities, it can be concluded that the teaching material delivered at the Robotics Workshop uses interactive multimedia which includes lectures, virtual demos, animations, visualizations, simulations and videos which have proven successful in motivating students in the motivated category with a score of 3.84 and increasing scientific literacy in the high category with a score of 3.93.

Abstract

This paper presents a low-cost hardware realization of a Type III compensated DC–DC buck converter with experimental validation under practical load conditions. The compensator is designed using MATLAB Bode plot analysis to achieve the target phase margin, and the resulting pole–zero configuration is verified through LTspice simulation before implementation on a microcontroller-based hardware prototype. Performance testing is conducted under both resistive and DC motor loads to evaluate improvements over an open-loop configuration. Experimental results show that the proposed closed-loop design significantly accelerates transient recovery, reducing settling time from 85–134 ms in the open-loop system to 0.39–5.2 ms in the compensated system, representing improvements of up to two orders of magnitude depending on the load. The closed-loop converter also achieves tighter steady-state regulation around 6 V and smaller effective voltage dips during load transients, confirming the effectiveness of the Type III compensator in enhancing both dynamic and steady-state performance. The implementation demonstrates a practical and cost-efficient approach for applying Type III compensation on low-cost hardware platforms suitable for educational and prototype-level power electronics applications.
