Abstract

In Vocational colleges, the high activity of students in the laboratory for practical activities, research, and others makes the use of the laboratory more optimal so that it is difficult to monitor its use. This results in a lack of information on the track record of laboratory use. So if the key and laboratory equipment are lost, it is very difficult to identify. The laboratory key security system based on Radio Frequency Identification (RFID) and Raspberry Pi is one solution that can be used for a security system compared to the conventional physical locker key system. This system uses Raspberry Pi as the main controller to control the lock mechanism on the locker. This system aims to provide convenience and security in the use of lockers using miniature computing technology. This system consists of Raspberry Pi as a control center, solenoid lock door to move the lock mechanism, LCD screen to display information to users, and RFID as a user authentication method before opening the locker. This tool is also able to inform the day and time of taking the locker key recorded on the website. By using this system, users can easily access the locker and can more easily find out the track record of taking the laboratory key. The results of the study, from 7 users registered in the system, all of them successfully opened the locker with a success rate of 100%. The response time to open and close the locker door is a maximum of 60 seconds. Users who access the locker can be recorded on the website regarding the date and time of locker access.

Abstract

This research developed a prototype of an Internet of Things (IoT)-based automatic drip irrigation system integrated with Google Sheets and an Android application based on MIT App Inventor. The system utilizes ESP32 and a soil moisture sensor to monitor soil moisture conditions in real-time and automatically control the water pump based on a moisture threshold value. The threshold value is determined by the user through the Android application and stored in Firebase and EEPROM, so the system can continue to operate even if the internet connection is lost. Data on soil moisture, pump status, threshold value, and recording time are recorded periodically every five minutes into a Google Sheet to support data monitoring and analysis. The test results show that the system has a humidity measurement error rate of 2.68%, which indicates that the performance of the sensor and control system is quite accurate and reliable. This system is suitable for application on small to medium-scale agricultural land and has the potential to be further developed with the application of artificial intelligence to improve irrigation efficiency

Abstract

Oil palm loose fruit collection is labor-intensive and can cause operator fatigue and low field efficiency. This study presents the design and performance evaluation of a 12 V DC-powered semi-automatic trolley for collecting loose fruits. The system combines a rotary sweeper, belt conveyor, and blower, all driven by DC motors and controlled using a simple ON/OFF circuit. Tests were conducted with loads of 2, 5, 7, and 10 kg. Evaluation covered collection and transport time, current consumption, power use, and operational stability. Operating time increased with load, reaching approximately 18, 26, 34, and 45 s, respectively. Although energy consumption rose at higher loads, the trolley remained stable and showed acceptable efficiency. Its integrated mechanism enables continuous collection, conveying, and cleaning while reducing manual effort and operator fatigue. The proposed trolley therefore offers a practical, ergonomic, and energy-efficient solution for improving productivity in oil palm plantations.

Abstract

Keterampilan praktik pengelasan merupakan salah satu kompetensi penting bagi siswa Sekolah Menengah Kejuruan (SMK) sebagai bekal memasuki dunia kerja, khususnya pada bidang manufaktur dan konstruksi. Kegiatan Pengabdian kepada Masyarakat (PkM) ini bertujuan meningkatkan keterampilan vokasional siswa SMK Negeri 2 Banda Aceh melalui pelatihan pengelasan dan fabrikasi meja serta kursi berbahan besi hollow. Kegiatan dilaksanakan selama dua hari, pada tanggal 25 s/d 26 Juni 2026, dengan melibatkan sekitar 20 siswa. Metode pelaksanaan meliputi pemberian materi dasar pengelasan, prosedur penggunaan peralatan, penerapan Keselamatan dan Kesehatan Kerja (K3), diskusi, demonstrasi, serta praktik langsung secara berkelompok. Tahapan praktik mencakup membaca gambar kerja, mengukur dan menandai material, pemotongan, perakitan, pengelasan, penggerindaan, finishing, serta pemeriksaan kualitas produk. Hasil kegiatan menunjukkan bahwa seluruh kelompok mampu menyelesaikan rangka meja dan kursi sesuai gambar kerja dengan konstruksi yang kokoh dan dimensi yang sesuai rancangan. Penilaian berdasarkan ketepatan ukuran, kualitas pengelasan, finishing, penerapan K3, dan kerja sama tim menghasilkan nilai akhir antara 88,6 s/d 95,4 dengan kategori sangat baik. Kegiatan ini memberikan pengalaman praktik secara nyata serta memperkuat keterampilan teknis, kedisiplinan, kerja sama, dan penerapan K3 bagi peserta
