Abstract

Perkembangan teknologi saat ini sangatlah berkembang dengan pesat, komunikasi sangat penting dan dibutuhkan, Peneltian ini bertujuan untuk merancang bangun sebuah perangkat Duplexer yang bekerja pada band 900 MHz pada jaringan radio hybrid. Duplexer adalah perangkat yang menggunakan satu antena pada frekuensi yang berbeda. Pada penelitian ini menggunakan metode kuantitatif, karena hanya satu antenna yang dapat berkomunikasi antara dua HT, duplexer didesain menggunakan mikrostrip sebagai resonator. Komponen L dan C pada mikrostrip ini menggunakan teknik open circuit untuk kapasitor dan short circuit untuk induktor. Duplexer diperoleh dengan memanfaatkan respon frekuensi band stop filter (BSF). Frekuensi yang digunakan pada band 900 Mhz yang mana frekuensi uplink adalah 453,025 MHz – 463,025 MHz dan frekuensi downlink 458.025 MHz – 468.025 MHz.Hasil pengujian diperoleh redaman pada cut off mencapai 12 db. Redaman ini merupakan tingkat isolasi sinyal antara sinyal uplink dan downlink.

Abstract

Penelitian ini bertujuan merancang dan membangun sistem pelacakan mortir latih menggunakan antena Yagi pada frekuensi 433 MHz berbasis Arduino. Metode yang digunakan adalah eksperimen untuk menguji hipotesis mengenai kemampuan sistem dalam mendeteksi dan melacak mortir latih. Penelitian ini dilakukan melalui tiga tahap: perancangan, implementasi, dan evaluasi. Pada tahap perancangan, desain antena Yagi, pemilihan komponen, dan perancangan rangkaian sistem ditentukan. Implementasi melibatkan penyusunan dan pengujian sistem pelacakan dengan Arduino sebagai pengontrol, yang mengarahkan antena menggunakan servo motor berdasarkan sinyal yang diterima. Evaluasi dilakukan dengan menguji akurasi sistem dalam melacak mortir latih. Hasil penelitian menunjukkan bahwa sistem dapat melacak pergerakan mortir dengan akurasi yang cukup baik meskipun ada keterlambatan respons saat mortir bergerak cepat dan gangguan sinyal yang mempengaruhi akurasi. Meskipun demikian, sistem ini terbukti efektif dan dapat dikembangkan lebih lanjut untuk meningkatkan kinerjanya, terutama dalam hal pengolahan sinyal dan jangkauan pelacakan.

Abstract

The utilization of automated systems to increase crop maintenance efficiency, especially in fertilizer and pesticide application, has been prompted by advancements in precision agriculture technology. Using a camera module as an automated spraying controller to detect leaf images is one creative method. The integration of the Raspberry Pi v2 Camera Module with digital image processing methods in automated spraying systems is the subject of a comprehensive review of earlier research presented in this article. Actuator control in the system, analysis of leaf detection techniques, and a review of recent journal literature are some of the techniques employed. The study's findings show that real-time implementation of this technique which includes color thresholding and texture analysis for leaf detection can be accomplished with good accuracy. The Raspberry Pi v2 Camera Module offers advantages in color image and easy integration with microcontroller. In conclusion, an automated spraying system based on leaf image detection shows great potential in reducing chemical waste and improving spraying precision, although challenges remain related to lighting conditions and crop types. Further research is needed to improve system performance under various field conditions.

Abstract

The development of drone technology has driven innovation in the integration of surveillance and weapons systems. This research designs and builds a First Person View (FPV) camera gimbal controller system that can be synchronized directly with the movement of the NR version of the SS2 weapon platform on a quadcopter drone. This system utilizes an Inertial Measurement Unit (IMU) sensor to read the drone's orientation and adjust the gimbal position in real-time to maintain alignment with the target. Tests were conducted at various maneuver angles to verify the gimbal's accuracy, stability, and response to drone movements. The results show accurate synchronization with minimal latency. This controller system uses an STM32 microcontroller and an MPU-6050 IMU sensor as its main components, combined with precision servo motors for gimbal axis drive. The FPV camera is calibrated to remain focused on the SS2 weapon barrel in all orientation conditions. This system integration allows operators to monitor and accurately direct targets remotely via FPV video. Test data shows that the system's stability is maintained even under high vibration conditions and extreme movements. The implementation of this system has great potential for application in tactical military drone applications and security surveillance.
