Abstract

Low Power Wide Area Networks (LPWAN) applications are a major concern in infrastructure. Rural are areas that have a poor quality signal; the cause lies in the location of the rural regions away from the coverage area Base Transceiver Station (BTS) so that the need for telecommunications equipment in the form of Global System for Mobile communications (GSM) repeaters. GSM repeater devices require an antenna that has a large gain mainly on the receiving antenna, one antenna that has a large gain character is helix axial mode has a large dimension resembling a spring and has a directional radiation pattern properties, whereas the antenna with an omnidirectional radiation pattern is a patch meander line antenna has compact dimensions and is easy to fabricate. The meanderline patch antenna has the disadvantage one of which is the small gain caused by trapped surface waves on the ground. This research will discuss the design and realisation of helix axial mode, and patch meanderline Defected Ground Structure (DGS) for Low Power Wide Area Networks (LPWAN) application in a rural area so it can be used for Internet of Things (IoT) based weather monitoring. Integrating antenna helix axial mode as receiving antenna and antenna patch meanderline DGS as rebroadcast antenna in GSM repeater able to make edge network in a rural area become High-Speed Packet Access + (HSPA +) network. The test result IoT based obtained the value of Received Signal Strength (RSSI) an average of -89 dBm in HSPA+ network.

Abstract

Kendaraan otonom adalah kendaraan yang dapat bernavigasi tanpa ada intervensi manusia. Istilah otonom tidak hanya diterapkan untuk mobil tanpa awak tetapi juga untuk alat pengolah tanah yaitu traktor. Tidak semua orang bisa mengoperasikan traktor, dibutuhkan keahlian khusus untuk mengoperasikan alat tersebut, terutama bagi penyandang disabilitas, alat tersebut akan sulit dioperasikan bahkan tidak mungkin dapat dioperasikan tanpa bantuan teknologi tertentu. Terdapat dua teknik untuk melakukan pengolahan tanah, setiap teknik tersebut menghasilkan pola pengolahan tanah tertentu, yaitu pola pengolahan tanah bolak-balik dan pola pengolahan berkeliling, pola pengolahan tanah berkeliling memiliki pola yang sama dengan pola gerak sirkular. Artikel ini menguraikan tentang algoritma navigasi otonom dengan menerapkan Finite State Machine untuk menghasilkan pola pengolahan tanah berkeliling atau pola gerak sirkular. Pola pergerakan yang dihasilkan menunjukkan hasil yang lebih baik jika antena modul GPS diletakkan di atas kendaraan dibandingkan diletakkan di depan kendaraan. Pengujian dilakukan sebanyak 5 kali pada setiap peletakkan GPS. Hasil pengujian pada saat GPS diletakkan di atas kendaraan adalah 4 diantaranya menghasilkan jejak pola gerak sirkular. Algoritma yang digunakan mampu menghasilkan pola gerak sirkular dengan jarak antar sirkular kurang lebih 3 sampai 5 meter.

Abstract

The purpose of this research is to determine the effect of the physical coding of LoRa communications on monitoring water pipelines. Optimizing the performance of packet receivers in the LoRa communication system using coding on the physical parameters SF (spreading factor), BW (bandwidth), and CR (coding rate). The detection system consists of 3 sensor nodes, 3 intermediate nodes, and 1 receiver node. Data from these sensors is sent to a cloud database. The SX1278 LoRa communication module works using a 433 MHz frequency. During the transmission process on the LoRa communication system, optimization is carried out for receiving data packets using the parameter coding method of physical spread factors, bandwidth, and coding rate. As a result of the research, it is shown that the greater the value of the third parameter (SF, BW, and CR), such as improvement in packet reception performance, improvement in bit security, and increasing packet resistance to various disturbances in transmission, but the time required for sending data be longer. The optimal parameters for detecting pipe leak locations include SF 10, BW 500 KHz, and CR 4/8. The LoRa SX1278 scenario is optimal with a distance of 400 meters, where packet and byte reception are obtained 100%.
