Abstract

ABSTRAKPemerintah telah menyiapkan kandidat spektrum frekuensi 700 MHz, 2,3 GHz dan 26 GHz/28 GHz untuk teknologi 5G di Indonesia. Dibutuhkan desain antena dengan isolasi tinggi, mampu bekerja secara MIMO dengan struktur yang ringkas agar tidak menghabiskan ruang yang besar pada sirkuit smartphone. Pada penelitian ini dilakukan perancangan dan optimasi elemen antena folded monopole meander line dengan dimensi 31,5 x 16 mm yang dapat bekerja secara dual-band yaitu pada frekuensi 700 MHz dan 2,3 GHz. Kemudian diimplementasikan dalam dua rancangan konfigurasi 8 ports MIMO antena yang berbeda posisi penempatan portnya. Hasil simulasi menunjukkan konfigurasi 1 memiliki isolasi tinggi dan kinerja lebih optimal dibandingkan dengan konfigurasi 2, di mana RL < -10 dB pada kedua frekuensi kerja, isolasi tinggi tanpa adanya tambahan elemen decoupling yaitu >20,64 dB dan >16,94 dB pada frekuensi 700 MHz dan 2,3 GHz secara berurutan, ECC<0,1 dan efisiensi antena mencapai 71,4% dan 84,6% pada frekuensi 700 MHz dan 2,3 GHz secara berurutan.Kata kunci: 5G, antena, MIMO, dual-band, 700 MHz, 2,3 GHz, isolasi tinggi ABSTRACTThe Indonesian government has prepared frequency spectrum candidates for 5G technology at 700 MHz, 2.3 GHz and 26 GHz/28 GHz. It takes antenna design with high isolation, MIMO and compact structure. In this research, the design and optimization of an antenna element with a folded monopole meander line geometric shape with dimensions of 31.5 x 16 mm which can work in dual-band at frequency 700 MHz and 2.3 GHz. The antenna design implemented in two configuration of 8 ports MIMO antenna with different port placement positions. The simulation results show that configuration 1 has high isolation and more optimal performance than configuration 2, where RL < -10 dB at both frequencies, ECC<0.1, high isolation without additional decoupling elements at >20.64 dB and >16.94 dB and antenna efficiency reached 71.4% and 84.6% at frequency 700 MHz and 2.3 GHz, respectively.Keywords: 5G, MIMO, dual-band, 700 MHz, 2.3 GHz, high isolation

Abstract

The Dharma Bakti Waste Bank in RT. 55, Muara Rapak Subdistrict, is one of the waste banks that remains active in managing community waste. However, the utilization of organic waste is still limited to compost production, while alternative management methods, such as Black Soldier Fly (BSF) maggot cultivation, have not been optimized. This community service program aims to enhance the utilization of organic waste through BSF maggot cultivation as an alternative feed for livestock, particularly catfish, which are already being farmed by residents. The method used in this program began with an awareness session on the benefits of maggot cultivation, followed by the construction of BSF fly cages, as well as hands-on training and practice on cultivation techniques for residents. The evaluation was conducted by measuring the increase in residents’ understanding before and after the training, along with a community satisfaction survey regarding the activities carried out. The results indicate a 17.98% increase in residents' understanding of BSF maggot cultivation, reflecting the effectiveness of the education and training provided. Additionally, the community satisfaction survey showed that 90% of residents were very satisfied, while the remaining 10% were satisfied. This initiative concludes that, in addition to providing valuable learning experiences for residents, it also empowers them in maggot cultivation through education and training, enabling better optimization of organic waste processing into economically valuable resources.
