Pada ronde ke-100 energi sisa metode non-clustering hanya 52.700 Joule, sedangkan metode SFR masih 56.000 Joule. Perbedaan semakin signifikan pada ronde ke-200 (selisih 17.000 Joule) hingga ronde ke-303 (selisih 21.000 Joule), dengan total energi sisa SFR mencapai 54.000 Joule. Selain itu, SFR berhasil menghubungkan kembali node terisolasi mulai ronde ke-147 hingga akhir simulasi, sehingga tidak ada kehilangan data dan umur jaringan meningkat secara signifikan. Dari hasil penelitian dapat disimpulkan bahwa penerapan metode SFR pada jaringan LoRa WSN mampu meningkatkan efisiensi energi, memperpanjang umur jaringan, dan menjaga konektivitas antar node. Metode ini dapat menjadi solusi efektif untuk optimasi komunikasi pada sistem sensor nirkabel berskala luas.","\u003Cp>Penelitian ini membahas implementasi metode Second fold relay (SFR) sebagai solusi untuk merekoneksi node terisolasi dalam jaringan LoRa Wireless Sensor Network (WSN).
