Abstract

Kelompok Tani Ngambarsari terletak di Mangunsari Kota Semarang Jawa Tengah mengalami permasalahan pertanian yaitu serangan hama burung pipit dan ketidaksesuaian tingkat keasaman tanah. Solusi permasalahan ini berupa alat pengusir hama burung dengan sensor pH berbasis Internet of Things (IoT). Alat ini menggunakan energi surya dan diakses melalui aplikasi smartphone. Metode pelaksanaan mencakup pembentukan tim, survei, desain perancangan alat, pembuatan alat dan aplikasi, uji coba, pembuatan buku pedoman, sosialisasi, implementasi, dan evaluasi. Hasil pengujian menunjukkan peningkatan signifikan dalam produktivitas pertanian. Alat ini dapat meningkatkan hasil panen gabah menjadi beras dari 55% menjadi 60% dalam 90 m2, dengan keuntungan 177,12 kg beras per 90m2 dibandingkan dengan kondisi sebelumnya. Implementasi sensor pH tanah pada alat ini membantu petani dalam mengelola pupuk dengan mengontrol tingkat keasaman tanah secara real-time.

Abstract

Abstrak Krisis lingkungan dan iklim global menuntut pendidikan untuk turut serta dalam solusi melalui pendekatan Greening Education, sebagaimana diinisiasi oleh UNESCO. SMK Negeri 1 Puring yang memiliki visi ramah lingkungan menjadi mitra dalam kegiatan pengabdian masyarakat bertajuk Greening Education 101, yang bertujuan meningkatkan kompetensi civitas akademika dalam aspek pengetahuan, keterampilan, sikap, dan nilai konservasi lingkungan. Kegiatan menggunakan pendekatan manajerial POAC (Planning, Organizing, Actuating, Controlling) yang diterapkan pada seluruh tahapan pelaksanaan. Metode pelatihan terdiri atas ceramah, tanya jawab, demonstrasi, praktik mandiri, dan pendampingan. Evaluasi dilakukan melalui pretest-posttest. Pelatihan diikuti oleh 24 peserta pada tanggal 11 Juni 2025 dan menghasilkan peningkatan signifikan pada seluruh aspek. Pengetahuan meningkat dari 38% menjadi 88%; keterampilan dari 25% ke 56%; sikap dari 88% ke 100%; dan nilai konservasi dari 44% ke 81%. Hal ini menunjukkan efektivitas pelatihan dalam menginternalisasi prinsip greening education. Namun, pelaksanaan hanya satu hari menjadi kendala dalam pendalaman materi dan pengukuran outcome jangka panjang. Partisipasi peserta juga bervariasi, dengan dominasi komunikasi satu arah. Pelatihan Greening Education 101 efektif dalam meningkatkan kompetensi peserta di bidang pendidikan berkelanjutan. Diperlukan pelatihan lanjutan berdurasi lebih panjang dan pendekatan komunikasi dua arah untuk mendukung transformasi lingkungan sekolah secara menyeluruh. Kata kunci: greening education; pendidikan lingkungan; SMK; sustainable development. Abstract The global environmental and climate crisis demands that education participate in solutions through the Greening Education approach, as initiated by UNESCO. SMK Negeri 1 Puring, with its environmentally friendly vision, became a partner in a community service activity entitled Greening Education 101, which aims to improve the competence of the academic community in the aspects of knowledge, skills, attitudes, and values of environmental conservation. The activity uses the POAC (Planning, Organizing, Actuating, Controlling) managerial approach, which is applied at all stages of implementation. The training includes lectures, questions and answers, demonstrations, independent practice, and mentoring. Evaluation was carried out quantitatively and qualitatively through pretests and posttests. Twenty-four participants attended the training and significantly improved all aspects. Knowledge increased from 38% to 88%; skills from 25% to 56%; attitudes from 88% to 100%; and conservation values from 44% to 81%. This demonstrates the effectiveness of the training in internalizing the principles of greening education. However, the one-day implementation hampered in-depth understanding of the material and the measurement of long-term outcomes. Participant participation also varied, with one-way communication predominating. The Greening Education 101 training effectively improved participants' competencies in sustainable education. Further, longer training and a two-way communication approach are needed to support comprehensive school environmental transformation. Keywords: environmental education; greening education; sustainable development; vocational high schools.

Abstract

Brushless DC (BLDC) motor is a three-phase motor that cannot work directly with DC current but requires electronic commutation to replace the brush function in DC motor. This paper aims to implement BLDC motor driver integration based on bootstrap circuit using Autodesk Eagle. The driver board consist of bootstrap circuit based on IR2110, MOSFETs, three voltage regulator, ESP32 microcontroller and ACS712 current sensor connection, logic level converter, and BLDC hall effect signal sensor conditioning. The research proposes bootstrap capacitor calculation based on charging/discharging capacitor principle and the minimum motor speed rotation. The implemented driver has 14x10 cm dimension tested to drive 24V/135W/6000rpm sensored BLDC motor using six steps commutation with pulse width modulation (PWM) inserted programmatically in ESP 32 to drive the high side MOSFET of the driver without AND gate circuit. The effect of pwm frequency and dutycycle variation to the speed and current of the motor is investigated. The results showed that the driver with both 12 V and 24 V voltage source and 68 μF bootstrap capacitor work optimally in 20 KHz PWM frequency both in open loop and closed loop speed control test. The motor reach 129 W for the largest power and 5250 rpm for the fastest speed in 24 V supply.

Abstract

Recent advancements in sensorless Field-oriented Control (FOC) of Surface Permanent Magnet Synchronous Motors (SPMSMs) have improved system reliability and cost-effectiveness. However, limitations such as speed chattering and inaccurate rotor position estimation remain problematic for Electric Vehicle (EV) applications. This study developed a sliding mode observer-phase locked loop (SMO-PLL) algorithm applied to sensorless FOC in SPMSMs. The SMO predicts the back EMF of the SPMSM, which the PLL then uses for precise rotor position and speed estimation. Simulations conducted in MATLAB Simulink demonstrate that the SMO-PLL significantly reduces chattering and achieves a rotor position estimation error of only 1 rad/min. While the quantitative integral error criteria for SMO-PLL (IAE: 0.0868, ITAE: 0.3069, ISE: 0.0229, ITSE: 0.0834) are slightly higher than those of Field Observer (FO) and Extended Electromagnetic Field Observer (EEMFO), speed control analysis confirms that SMO-PLL delivers a rapid steady-state response with minimal overshoot and oscillation. These findings are crucial for applications where speed stability is essential for passenger comfort and safety, highlighting the SMO-PLL's potential as a robust sensorless control solution for future EVs.
