Abstract

Quadcopter is an Unmanned Aerial Vehicle (UAV) that uses 4 motors arranged crosswise as a propulsion system. The quadcopter's capabilities are supported by a main component called the flight controller or control system. The operation of this unmanned aircraft is controlled automatically through a program run from the GCS (Ground Control Station) so that the quadcopter can fly according to the desired destination. The control system is needed to maintain the balance of the quadcopter while flying and maneuvering to remain stable. PID (Proposional Integral Derivative) method as a counterweight when manoeuvring on the y-axis (pitch) and x-axis (roll) and Kalman Filter as processing the resulting sensor output. The results of this study show that setting the value for the proportional constant (Kp), integral constant (Ki) and derivative constant (Kd) determines the quadcopter can fly or maneuver well. The gain values used are Kp of 0.135, Ki of 0.135 and Kd of 0.003. However, the output generated by the gyroscope in pitch and roll still has noise caused by the vibration of the mover during flight and maneuvering. So the Kalman filter is needed to find out the value that is close to the actual output of the gyroscope.

Abstract

Quadcopter is a type of UAV (Unmanned Aerial Vehicle) which is currently developing and very useful in various fields. With four motors as the main propulsion, the quadcopter has the ability to maneuver, take-off and land vertically in places that have limited space. However, in an autonomous system, the quadcopter is still difficult to operate, one of which is to keep it stable, when in a position where there is minimal GPS signal. Therefore, in this study, we will use the Blob detection method that uses the OpenCV library to determine the landing place and is assisted by an optical flow sensor, aiming to catch roll, pitch and yaw motions. The results of this study indicate that the accuracy of the lidar sensor as a height sensor with an accuracy of 82.16 % is more accurate above 30 cm, the results of distance accuracy for image processing successfully detect up to a height of 600 cm with a light intensity value of around 50-70 lux. optical flow, light intensity and altitude distance greatly affect the motion produced by the quadcopter, but it can still move stably at a minimum value of light intensity of approximately 300 lux at an altitude of 300 cm.

Abstract

In the current era of 4.0 technology, there are many quadcopter applications for testing and usability in life) to monitor the surrounding environment while operating and navigate through the GCS depending on the purpose made. Therefore, the operation of the drone is controlled directly by the operator through certain communication networks such as remote control or automatically through devices that have been previously programmed. This is necessary in order to make it easier to move the drone and monitoring can be done through operator directions or image processing. Image Processing in the form of a QR Code that can provide directions to the drone so that navigation can run smoothly. Research using how the camera detects QR Code will give directions to the drone to navigate to make movements following the QR Code directions in a sequence of numbers so that the final result in the form of video can be viewed via GCS and camera via IP CAM. The results of this study indicate that the drone can detect QR Code and opencv also successfully translates pixels is a distance of 5 meters and navigating based on pixel size with more than 100 pixels, the drone can move automatically to a certain destination. With a distance of 1 meter, it produces 100 pixels on the x-axis and 108 pixels on the y-axis, while for the furthest distance from the QR Code, which is 5 meters, it produces 50 pixels on the x-axis and 80 pixels on the y-axis.

Abstract

Gubeng Station under PT. KAI DAOP 8 Surabaya requires a backup power source, such as a backup battery as a replacement for the main battery, to ensure continuous operation of the station. So, regular maintenance is carried out for the backup battery by charging them. However, there is no monitoring system for battery charging because the internet access at a distance of ±37.92 meters via Ethernet and voltage data after charging has turned yellow making maintenance and monitoring of charging difficult. Therefore, this research aims to develop a battery charging monitoring system with a LoRa-based ethernet network. When testing this system by charging a 12 VDC 65 Ah battery, the system can monitor the voltage and charging current values using a voltage sensor and ACS712 recorded in real-time in the Android application with an ethernet-based LoRa module with a maximum distance between the sending and receiving devices of 97, 9 meters in non-LoS conditions. The system also succeeded in auto cut off and sent a notification in the application when charging was complete with a recorded voltage and current of 14.01 V -0.22 Amperes.

Abstract

Teknologi jaringan komunikasi merupakan serangkaian komponen teknologi yang saling berkaitan satu dengan lainnya. Teknologi yang banyak digunakan di kehidupan sehari-hari adalah jaringan Wifi dan 4G. Dengan adanya jaringan-jaringan tersebut akan mempermudah kebutuhan akan internet. Namun perbedaan kecepatan dalam mengakses perlu dilakukan pengujian secara langsung terhadap jaringan tersebut. Untuk mendapatkan jaringan dengan layanan baik maka diperlukan Quality of Service (QoS) yang baik pula. Oleh karena itu penulis melakukan pengujian jaringan Wifi Universitas Qamarul Huda Badaruddin dan membandingkan dengan hotspot 4G XL yang ada di lokasi yang sama. Pengujian ini berfokus pada tiga parameter yaitu bandwidth, bitrate, dan buffer events. Hasil yang diperoleh adalah jaringan 4G XL lebih baik terhadap jaringan Wifi Universitas Qamarul Huda Badaruddin, dimana jaringan Wifi Universitas Qamarul Huda Badaruddin hanya mendapatkan bandwidth sebesar 39012.79 MB dan bitrate 21906.40 Kbps. Untuk buffer events, kedua jaringan sangat baik karena tidak ada waktu jeda (0s).

Abstract

Teknologi OpenRAN memungkinkan fleksibilitas jaringan seluler dengan memisahkan perangkat keras dan lunak, mengurangi ketergantungan pada vendor tunggal. Namun, implementasi OpenRAN berbasis Software Defined Radio (SDR) masih menghadapi tantangan dalam kualitas sinyal dan performa, terutama pada jaringan LTE skala kecil. Penelitian ini mengimplementasikan jaringan LTE menggunakan platform open-source Software Radio Systems Radio Access Network (srsRAN) dan perangkat SDR USRP B210, dengan fokus meningkatkan kualitas layanan melalui fitur seperti dynamic scheduling, dan alokasi Physical Resource Block (PRB). Jaringan dibangun dalam skema non-standalone dengan Evolved Packet Core (EPC) lokal, membentuk koneksi point-to-point antara dua User Equipment (UE) melalui eNodeB. Pengujian dilakukan selama 30 menit dalam lingkungan terkendali, dengan variasi jumlah PRB mulai dari 15 sampai 50. Hasil pengujian menunjukkan kedua UE berhasil terhubung: User 1 mencatat RSRP -83 dBm dan RSRQ -9 dB, sedangkan User 2 mendapat RSRP -82 dBm dan SNR 13 dB—nilai yang tergolong baik menurut standar 3GPP (RSRP > -90 dBm). Pengujian throughput FTP menunjukkan performa lebih tinggi di jaringan lokal (User 1: 2,7 MB/s, User 2: 1,3 MB/s), sementara speedtest HTTP ke cloud server memberikan kecepatan lebih besar, menunjukkan pengaruh backhaul. Analisis QoS dengan Wireshark mencatat throughput User 1 sebesar 21,288 KB/s (packet loss 0,96%) dan User 2 sebesar 13 MB/s (packet loss 0,97%). Peningkatan jumlah PRB meningkatkan bandwidth dan throughput, membuktikan efektivitas optimasi parameter di srsRAN. Penelitian ini mendemonstrasikan bahwa optimasi melalui fitur-fitur srsRAN berpotensi meningkatkan kinerja jaringan LTE berbasis SDR, yang relevan untuk dikembangkan dalam konteks jaringan privat maupun komunitas.
