Abstract

Industri 4.0 telah diperkenalkan sejak tahun 2011 di Jerman dan sudah mengalami banyak perkembangan dan telah diterapkan di berbagai penjuru dunia, tidak terkecuali di Indonesia. Berkembangnya industri 4.0 tentu saja perlu didukung dengan perkembangan ilmu pengetahuan lain pendukungnya salah satunya autonomous robot. Pada industri 4.0, robot sendiri memiliki peran penting untuk menjalankan proses otomasi di industri. Salah satu kunci keberhasilan revolusi industri 4.0 bergantung pada kemampuan sekolah dan perguruan tinggi dalam memberikan ilmu robotika pada siswa didiknya. Salah satu jenis robot yang dapat digunakan sebagai pembelajaran robotika pada siswa adalah robot line follower digital. Sekolah Alam Nurul Furqon sebagai salah satu lembaga pendidikan di Kabupaten Rembang tentu saja tidak ingin tertinggal mengikuti perkembangan teknologi robot untuk meningkatkan kualitas anak didiknya. Oleh karena itu, Tim dosen Polines memberikan solusi dengan memberikan pelatihan perakitan robot line follower digital pada siswa Sekolah Alam Nurul Furqon. Penggunaan robot line follower digital terbukti dapat menjadi media interaktif yang tepat untuk memperkenalkan robot dan meningkatkan keterampilan yang dibutuhkan untuk dapat membuat robot. Berdasarkan hasil dari kegiatan menunjukkan tim dari Politeknik dapat membantu pengelola dan guru Sekolah Alam Nurul Furqon dalam menyelesaikan masalah kurangnya pengetahuan mengenai robot dan keterampilan dalam pembuatan robot sehingga siswa Sekolah Alam Nurul Furqon dapat mengikuti perkembangan teknologi di era industri 4.0.

Abstract

This paper presents a performance comparison of the circular patch unit cell as a unit cell for reflector application at 3.5 GHz frequency using a dielectric substrate between FR4 and F4BMX220 substrates. A circular patch is chosen as the unit cell of a reflector because it is commonly used, fabricated, and has a wider bandwidth compared to other structures. A performance comparison of the circular patch on both dielectric substrates is presented in a graph of S-parameters, reflection phase, and operating bandwidth, as well as in the table of dimensions, where the result is performed by simulation using CST software. Based on the simulated results, the F4BMX220 has a better performance compared to the FR4 in terms of the reflection value, operating bandwidth, and dielectric substrate thickness. However, a circular patch diameter when using the F4BMX220 is bigger than when using the FR4 substrate because the FR4 substrate has a higher dielectric constant than the F4BMX220, which is twice the F4BMX220 dielectric constant. Also, the F4BMX220 substrate has a narrower bandwidth compared to the FR4 substrate, which is a difference of around 0.1 GHz. The circular patch when using the F4BMX220 substrate has 0.96 of a reflection value, 0.007 of an absorption value, -6.77° of the reflection phase, and 0.24 GHz of the operating bandwidth at the normal incident wave angle (0°). Also, it can be properly worked if the incident wave angle is moving until 60°. The F4BMX220 substrate has the best performance compared to the FR4 substrate because the reflection value is much better value, even at the incident wave angle of 60°.

Abstract

Tempat Pembuangan Akhir (TPA) merupakan lingkungan kerja dengan risiko tinggi terhadap kecelakaan dan penyakit akibat kerja. Rendahnya kepatuhan pekerja dalam menggunakan Alat Pelindung Diri (APD) menjadi salah satu faktor utama yang meningkatkan risiko kecelakaan. Pengawasan manual yang dilakukan selama ini terbukti kurang efektif karena keterbatasan tenaga pengawas dan luasnya area kerja. Pengabdian ini mengusulkan penerapan sistem APDWatch berbasis Smart Computer Vision yang mengintegrasikan model deteksi objek YOLOv8m dan model klasifikasi multi-output VGG16 untuk mendeteksi penggunaan APD secara otomatis. Sistem ini mampu memberikan notifikasi real-time kepada pengawas ketika ditemukan pelanggaran penggunaan APD. Hasil evaluasi menunjukkan nilai mAP@50 sebesar 0,9514 untuk YOLOv8m dan rata-rata F1-score 0,8927 pada atribut helm, rompi, dan sepatu menggunakan VGG16. Implementasi sistem pada perangkat IoT berbasis Raspberry Pi dengan kamera menunjukkan kemampuan berjalan secara real-time dengan latensi kurang dari 2 detik. Program pengabdian ini dilaksanakan di CV Berkah Jaya Mandiri Semarang dengan luaran berupa aplikasi web monitoring, artikel ilmiah, dan HKI hak cipta aplikasi. Penerapan sistem ini diharapkan dapat meningkatkan kesadaran pekerja tentang pentingnya penggunaan APD serta mengurangi angka kecelakaan kerja di sektor pengelolaan sampah.

Abstract

Efficient storage and retrieval of electronic components remain challenging in laboratory-scale environments due to reliance on manual handling. This study presents the development and experimental evaluation of a laboratory-scale three-axis Automated Storage and Retrieval System (ASRS) prototype designed for electronic component management. The proposed system uses a combination of servo and stepper motors to provide controlled motion along the X, Y, and Z axes. It is managed by a Programmable Logic Controller (PLC) integrated with a Human–Machine Interface (HMI). Manual operation is used for system calibration and motion adjustment, while automatic operation facilitates sequential storage and retrieval processes. We evaluated the system's performance by measuring positional accuracy and deviation at multiple target rack locations. The results show that the system achieves positioning accuracy of 84.62% - 95.38%, with absolute deviations between 0.3 and 1 cm. These findings demonstrate that the ASRS prototype is a feasible solution for effective laboratory-scale automation in storage applications and for PLC-based educational purposes.

Abstract

The community service activity conducted with the partner GreenFarm Hydroponic aims to address the partner’s issue of conventional temperature regulation in the hydroponic system, where temperature levels fluctuate depending on environmental conditions. This instability reduces dissolved oxygen levels and inhibits plant growth. The activity includes training on the installation and operation of an automatic water-cooling system. The developed cooling system utilizes an Outseal Mega V2 Slim, NodeMCU ESP32, DS18B20 temperature sensor, evaporator chiller, outdoor AC unit, LCD, relay, contactor, and Blynk-based monitoring. This device is capable of maintaining water temperature at the ideal level of 27°C through both automatic and manual modes. The implementation of this technology not only enhances temperature stability and production quality but also facilitates remote monitoring and reduces manual intervention. This program demonstrates the role of vocational higher education in providing practical technological solutions that support the sustainability of hydroponic enterprises. The activity was successfully carried out, with GreenFarm Hidroponik now able to operate the automatic cooling system either via panel buttons or through the Blynk IoT application.
