Abstract

Partnerships between universities and partner institutions are strategic for study program accreditation and for implementing the Tri Dharma of Higher Education. In 2025, Al-Azhar University established an international collaboration with Universiti Malaysia Perlis (UniMAP) and the Village Forest Management Institution (LPHD) of Pasar Rawa, Langkat Regency, in the field of community service. The activities included a networking session, strategic discussions on converting palm oil plantations back into mangrove forests, and a joint mangrove planting action. This initiative aims to restore coastal ecosystems as habitats for marine life, such as fish, crabs, and shrimp. Through this synergy, it is expected that the motivation of the Pasar Rawa Village community, particularly the LPHD, will increase in managing and preserving the mangrove area sustainably for the welfare of the coastal ecosystem.

Abstract

Abstrak Pendampingan ini diberikan dikarenakan minimnya pengajar di sekolah yang memahami robotik dan sarana yang kurang mendukung. Sehingga pendampingan ini diperlukan karena minimnya pengetahuan para pelajar dalam merakit robot. Pendampingan perancangan ini diberikan kepada siswa-siswa kota Medan untuk mengenalkan konsep dasar elektronika sehingga pelajar tersebut semakin tertarik tentang robotika. Pendampingan ini diberikan oleh staff Teknik Elektro UNPRI. Peserta yang hadir dari jenjang SD, SMP dan SMA dengan total 70 orang. Dalam pendampingan ini siswa akan diberikan motivasi dan materi merakit robot Smart Botanical Garden. Lalu siswa akan dipecah berdasarkan kelompok jenjang pendidikan. Adapun tingkat kesulitan setiap kelompok akan disesuaikan dengan jenjang pendidikannya. Setiap kelompok akan dipersiapkan dengan komponen robot. Dan layout disediakan untuk tempat testing dan running hasil rakitan. Hasil pendampingan ini adalah siswa-siswa semakin memahami komponen dan fungsinya dan selektif memilih komponen yang akan dipakai dalam perakitan. Kata kunci : pendampingan; robot; perakitan; komponen Abstract This support is rendered due to the deficiency of educators in schools knowledgeable in robotics and the insufficient infrastructure. Consequently, this mentorship is essential owing to the students' inadequate understanding of robot assembly. This design mentoring is offered to students in Medan to familiarize them with fundamental electrical ideas, consequently enhancing their interest in robots. This guidance is provided by the staff of the Electrical Engineering Department at UNPRI. The participants, numbering 70 individuals, represent elementary, middle, and high school levels. During this mentorship session, students will receive motivation and resources to construct the Smart Botanical Garden robot. The kids will thereafter be categorized into groups according to their educational levels. The challenge level for each group will be modified based on their educational attainment. Every group will receive robotic components. A layout will be supplied for the evaluation and execution of the combined outcomes. This coaching results in students gaining a deeper understanding of the components and their functions, enabling them to be discerning in their selection of components for assembly. Keywords: coaching; robot; assembly; components

Abstract

This study presents the design and simulation of a State Feedback Controller (SFC) for speed regulation of a Permanent-Magnet DC (PMDC) motor using a state-space modeling approach. The objective is to achieve stable and accurate speed control under dynamic load disturbances that typically degrade the performance of conventional open-loop systems. The Direct Current (DC) motor is modeled in state-space form, with armature current and angular speed selected as the main system states. Controller gains are designed using the pole placement method to ensure fast response and improved stability. The proposed SFC is evaluated through MATLAB®/Simulink® simulations by examining motor speed, armature current, and input voltage responses under step-load variations. Simulation results show that the SFC maintains the motor speed at the reference value of 3,430 rpm even during sudden load increases, whereas the uncontrolled motor experiences significant speed drops and oscillations. Performance analysis confirms notable improvements in transient response. The rise time is reduced from 1.1864 s to 0.4220 s, and the settling time decreases from 2.1132 s to 0.7517 s, indicating faster and more stable system behavior. In addition, smoother current transitions and more efficient voltage regulation are achieved compared to the open-loop configuration. Overall, the results demonstrate that state-space control using pole placement provides a robust and responsive alternative to conventional PID controllers for DC motor speed control under load disturbances. Future work will focus on experimental validation and the exploration of advanced control strategies such as Linear Quadratic Regulation and adaptive control.
