Abstract

This paper discusses the design, simulation, and realization of a leaky-wave microstrip antenna with multiple slots and defected ground structure (DGS). The leaky-wave microstrip antenna with multiple slots and DGS was designed to operate at 5.925-6,425 GHz for wireless local area network applications (WLANs), with a gain of ≥4dBi. The antenna uses FR-4 epoxy as the substrate with a dielectric constant of 4.6 and a thickness of 1.6 mm. The leaky-wave microstrip antenna has dimensions of 45.1 mm × 24.8 mm × 1.6 mm, while the leaky-wave microstrip antenna with multiple slots and DGS has dimensions of 40.6 mm × 25 mm × 1.6 mm. The simulation results showed that adding multiple slots and DGS to the leaky-wave microstrip antenna increased the bandwidth from 280 MHz (5.859–6.139 GHz) to 691 MHz (5.854–6.545 GHz) while the gain increased from 4.47 to 5.04 dBi. Meanwhile, the measurement results showed that the bandwidth parameter increased from 273 MHz (5.877–6.150 GHz) to 684 MHz (5.845–6.529 GHz) and the gain parameter from 4.53 to 5.06 dBi at 6 GHz.

Abstract

In the study of Internet of Things (IoT) Based Control System Simulation for Monitoring and Extermination of Rat Pests in Agricultural Land. The method used in this study is the simulation of rat movement, detection using PIR (Passive Infrared Sensor) connected to the LoRa Node, and sending to the LoRaWAN Gateway for sending to the cloud for the monitoring system. The detection data were analyzed using heatmaps and graphs of the number of detections per time for the installation of sensors and automatic traps. The simulation includes scenarios of node-gateway distance, antenna height, and vegetation density, as well as performance evaluation with confusion matrix metrics (TPR, FPR), latency, and trigger success. The results show stable motion detection with low latency at a coverage of hundreds of meters per gateway, while reliability increases significantly when the antenna is increased and the number of gateways is optimized. LoRa/LoRaWAN is proven to be adequate for low-power telemetry in agricultural land and is compatible with ecological-based rat control strategies.

Abstract

Kegiatan pengabdian ini bertujuan untuk meningkatkan kesiapan pedagogik guru di Desa Singasari, Jonggol dalam pemanfaatan kecerdasan buatan/Artificial Intelligence (AI) untuk mengembangkan media pembelajaran. Masalah yang dihadapi adalah rendahnya adopsi AI, belum adanya standar penulisan prompt, dan kebutuhan literasi etika penggunaan AI. Kegiatan dirancang untuk menilai dampak pelatihan terhadap kompetensi guru dan kualitas produk ajar. Metode yang digunakan adalah pelatihan luring bagi 22 guru dari mata pelajaran dengan desain pretest serta posttest, praktik terarah, penugasan pembuatan media dan kuesioner singkat. Hasil penelitian ini rata-rata pretest sebesar 88,18 meningkat 97,73 pada posttest, dengan rata-rata kenaikan rata-rata 9,55 poin, hasil juga menunjukkan seluruh peserta mencapai kelulusan dengan nilai pascapelatihan minimal ≥ 80 mencapai 100%, N-Gain memiliki rata-rata 0,81 atau memiliki efektivitas tinggi, perbedaan signifikan terhadap uji t berpasangan sebesar (t(21) = 4,11 dengan p = 0,0005) dan memiliki efek besar (Cohen’s d = 0,88). Berdasarkan hasil peserta menunjukkan peningkatan pengetahuan dan pemahaman lebih baik terhadap rambu-rambu etika penggunaan AI. Hasil dari pelatihan singkat dengan alur penulisan prompt yang terstandar dikombinasikan dengan verifikasi serta penyelarasan dengan kurikulum dan pengetahuan pedagogis, secara efektif meningkatkan kesiapan pedagogik dan kepercayaan diri guru dalam menggunakan ChatGPT sebagai alat bantu pembelajaran bukan sebagai konten utama. Tindak lanjut yang disarankan adalah memantau dampak hasil belajar siswa, pelatihan lebih lanjut tentang penggunaan AI untuk membantu pembelajaran dan penegasan bahwa AI berperan sebagai alat bantu bukan sebagai konten.

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.
