Abstract

Teknologi OpenRAN memungkinkan fleksibilitas jaringan seluler dengan memisahkan perangkat keras dan lunak, mengurangi ketergantungan pada vendor tunggal. Namun, implementasi OpenRAN berbasis Software Defined Radio (SDR) masih menghadapi tantangan dalam kualitas sinyal dan performa, terutama pada jaringan LTE skala kecil. Penelitian ini mengimplementasikan jaringan LTE menggunakan platform open-source Software Radio Systems Radio Access Network (srsRAN) dan perangkat SDR USRP B210, dengan fokus meningkatkan kualitas layanan melalui fitur seperti dynamic scheduling, dan alokasi Physical Resource Block (PRB). Jaringan dibangun dalam skema non-standalone dengan Evolved Packet Core (EPC) lokal, membentuk koneksi point-to-point antara dua User Equipment (UE) melalui eNodeB. Pengujian dilakukan selama 30 menit dalam lingkungan terkendali, dengan variasi jumlah PRB mulai dari 15 sampai 50. Hasil pengujian menunjukkan kedua UE berhasil terhubung: User 1 mencatat RSRP -83 dBm dan RSRQ -9 dB, sedangkan User 2 mendapat RSRP -82 dBm dan SNR 13 dB—nilai yang tergolong baik menurut standar 3GPP (RSRP > -90 dBm). Pengujian throughput FTP menunjukkan performa lebih tinggi di jaringan lokal (User 1: 2,7 MB/s, User 2: 1,3 MB/s), sementara speedtest HTTP ke cloud server memberikan kecepatan lebih besar, menunjukkan pengaruh backhaul. Analisis QoS dengan Wireshark mencatat throughput User 1 sebesar 21,288 KB/s (packet loss 0,96%) dan User 2 sebesar 13 MB/s (packet loss 0,97%). Peningkatan jumlah PRB meningkatkan bandwidth dan throughput, membuktikan efektivitas optimasi parameter di srsRAN. Penelitian ini mendemonstrasikan bahwa optimasi melalui fitur-fitur srsRAN berpotensi meningkatkan kinerja jaringan LTE berbasis SDR, yang relevan untuk dikembangkan dalam konteks jaringan privat maupun komunitas.

Abstract

This community service project aims to assist LPNU–UMKM Tani Sejahtera in improving the quality and marketing of organic fertilizer products made from goat manure through the implementation of halal-based digital marketing. UMKM Tani Sejahtera, which is engaged in processing goat manure into organic fertilizer, faces challenges in marketing, branding, and utilizing digital platforms. The service activities were carried out in three phases: preparation, implementation, and evaluation. During the preparation phase, intensive discussions were held to identify the main issues, while the implementation phase involved training on digital marketing, branding, and optimizing the use of social media and marketplaces. Additionally, product identity design emphasizing the halal aspect was carried out. The outcome of this mentoring includes increased understanding of digital marketing and branding, as well as strengthening production and sales capacity through digital platforms. The evaluation shows an increase in the motivation and understanding of the partners in utilizing digital marketing. It is expected that this program will continue to support the sustainability of the UMKM business and encourage them to optimize existing potential, expand markets, and improve their product competitiveness in broader markets.
