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

In the frequency spectrum of 5G technology, there are three sub-frequencies, namely low band, midband, and high band. For the midband frequency, such as 3.5 GHz, it requires high data speed and wide coverage to support Enhanced Mobile Broadband (eMBB) services with high quality. Therefore, antennas are needed to meet the transmitter and receiver requirements for the 3.5 GHz operating frequency. An antenna with small dimensions is necessary to be used in limited spaces, thus a rectangular microstrip antenna with slit method is designed. For this research, it is limited to simulations using HFSS 15 to find the maximum possible optimization values by adjusting patch dimensions, substrate, and strip line. The return loss result at the operating frequency of 3.5 GHz is -20.0202 dB, and the VSWR is 1.2216. The final step is to add the slit method, which aims to improve the return loss, VSWR, and reduce the antenna dimensions. The optimization result with the slit method is achieved with a patch width of 25.43 mm and a patch length of 19.67 mm. The VSWR value decreases by 0.0701, indicating improved performance. The magnitude gain of the antenna is 3.8253 dB at a theta angle of 360 degrees.

Abstract

Batur Village, Batur Sub-district, Banjarnegara District, faces challenges in managing water for agricultural purposes. The current manual irrigation system is time- and labor-intensive and increases the risk of pump damage. To overcome this, an Internet of Things (IoT)-based pump control system is implemented to improve efficiency and productivity. The system automatically activates the water suction pump based on the water level in the reservoir and sets the irrigation schedule. The implementation process includes site survey, system design, installation, training, and evaluation. The system allows farmers to monitor and control irrigation through a smartphone-based application. The implementation results show that the system can reduce manual work, minimize the risk of pump damage, and ensure optimal water availability. In addition, this technology supports more efficient water management, increases agricultural yields, and provides a positive economic impact for farmers.

Abstract

Micro, Small, and Medium Enterprises (MSMEs) producing cassava chips in Rejosari, Trisobo, Boja, Kendal Regency have significant economic potential due to the availability of local raw materials. However, manual production processes and simple packaging limit production efficiency and product competitiveness. This program aimed to improve production efficiency, product quality, and competitiveness through the application of appropriate technology combined with training and assistance. The implementation methods included problem identification, application of a cassava slicing machine, training on production equipment usage, packaging training using a plastic sealer, product labeling, and monitoring and evaluation. The results show that the cassava slicing machine significantly reduced processing time and produced more uniform slices. Packaging and labeling training improved product hygiene, appearance, and identity. Overall, the program positively impacted production efficiency, packaging quality, and the competitiveness of MSME cassava chip products in the local market.
