Abstract

Penelitian ini menyajikan perancangan dan implementasi model sistem informasi monitoring hama pertanian berbasis Long Range (LoRa) yang dikembangkan untuk area persawahan terpencil dengan keterbatasan jaringan internet. Serangan hama tikus berkontribusi besar terhadap penurunan produktivitas padi sehingga diperlukan sistem monitoring otomatis yang mampu mendeteksi pergerakan hama dan mengirimkan informasi secara real-time. Sistem yang dikembangkan mengintegrasikan sensor Passive Infrared (PIR) untuk deteksi gerakan, ESP32-CAM untuk akuisisi citra, aktuator ultrasonik untuk pengusiran hama, serta modul LoRa sebagai media transmisi jarak jauh. Data yang diterima diproses dan divisualisasikan melalui dashboard sistem informasi pertanian berbasis web yang menampilkan notifikasi deteksi, citra hama, serta histori monitoring. Hasil pengujian menunjukkan bahwa sensor PIR mampu mendeteksi pergerakan hingga jarak 3 meter dengan tegangan stabil. Komunikasi LoRa dapat beroperasi hingga jarak 300 meter dengan kehilangan paket minimal, sedangkan dashboard sistem informasi berhasil menampilkan aliran data secara real-time dan menyimpan rekam jejak monitoring secara terstruktur. Sistem ini dinilai sesuai diterapkan pada lingkungan pertanian dan mendukung praktik smart farming.

Abstract

This study aims to improve the performance of a microstrip leaky-wave antenna by adding a 1x3 array configuration and a V-slot structure for WLAN applications in the 5.925 − 6.425 GHz, using an FR-4 substrate with a dielectric constant of 4.6. Simulations were conducted to evaluate the parameters of S11, VSWR, bandwidth, and gain. The use of an array and V-slot aims to enhance both gain and bandwidth. Simulation results show the array and V-slot configuration achieved a bandwidth of 570 MHz (5.86 − 6.43 GHz) and gain of 7.02 dBi at 6 GHz. Compared to the microstrip leaky-wave antenna without a V-slot, the proposed configuration improved the bandwidth by 270 MHz (90%) and the gain by 0.82 dBi (13.3%). These results indicate that the addition of an array and V-slot structure effectively enhances antenna performance for wireless communication applications.
