Abstract

ABSTRAKContinuous Wave Radar (CW Radar) memiliki banyak aplikasi terutama dalam bidang kesehatan. CW Radar yang bekerja pada rentang frekuensi lebar memiliki keunggulan seperti bandwidth lebar, dan tingkat akurasi yang tinggi sehingga dapat digunakan untuk deteksi pergerakan dinding dada atau perut pada pernapasan. Namun, obstacle berupa pakaian dapat memengaruhi deteksi pernapasan manusia dengan sistem Radar. Pada penelitian ini dianalisis pengaruh pakaian terhadap deteksi pernapasan. Sistem Radar dimodelkan dengan Vector Network Analyzer (VNA), BladeRF, serta MATLAB untuk mengubah domain frekuensi menjadi domain waktu. Percobaan dilakukan pada empat jenis kain dengan jarak objek ke antena yaitu 45 cm. Diperoleh bahwa obstacle memiliki atenuasi kecil dan delay yang tidak signifikan, serta hasil BladeRF menunjukkan pola pernapasan dapat dideteksi. Sehingga disimpulkan bahwa obstacle tidak memengaruhi hasil pendeteksian pernapasan menggunakan sistem Radar.Kata kunci: CW Radar, deteksi pernapasan, pakaian, VNA, BladeRF. ABSTRACTContinuous Wave Radar (CW Radar) has many applications, especially in the health sector. CW Radar that works in a wide frequency range has advantages such as wide bandwidth, and a high level of accuracy so that it can be used for detection of chest or abdominal wall movement on breathing. However, obstacles in the form of clothing can affect the detection of human breathing with the Radar system. In this work, the effect of clothing on respiratory detection is analyzed. The Radar system is modeled with Vector Network Analyzer (VNA), BladeRF, and MATLAB to convert the frequency domain to the time domain. The experiment was carried out on four types of fabric with a distance of 45 cm from the object to the antenna. It was found that the obstacle has a small attenuation and insignificant delay, and the BladeRF results show that breathing patterns can be detected. So it is concluded that the obstacle does not affect the results of breathing detection using the Radar system.Keywords: CW Radar, respiratory detection, clothing, VNA, BladeRF.

Abstract

Images Recognition and Face Recognition are a form of artificial intelligence developed on Robots and Smart CCTV, such as technology currently developing, such as YOLO Real-time Object Detection and Images Recognition using Python language. In this research, the tool trying to be used is the ESP32 camera and his approach to several types of study, such as smart door locks. To activate this ESP32 camera, use the ATmega 328 mini Microcontroller, Arduino board, and FTDI Programmer. The thing that can be analyzed is the delay or inference time (ms) on the ESP32 camera. Face recognition technology in this research is devoted to using the ES32 camera, which is expected to be an inexpensive image recognition solution. This research using the ESP32 camera was made as easy as possible to be applied by everyone, but by not leaving the analysis side, one of which is on the time side of the camera's detection of the object in front of it, how far and fast (ms), this object can be explicitly detected. Speed is seen from the resolution specifications used for face recognition and image recognition, such as CIF and QVGA, and throughput (bytes) analysis of ESP32-Cam and Server using Wireshark.

Abstract

Antenna miniaturization has become one important research, especially in mobile communication technology development. This paper presents the development of a miniaturized antenna for RFID application (924 MHz). Meandering technique has been adopted to create a geometrically small antenna relative to its operating frequency. Measurement result shows that the fabricated antenna inherits low return loss, down to -25.915 dB. The geometry of the antenna is 25.54 mm x 16 mm, which is much smaller than its resonance wavelength (0.079? x 0.049?). The measured gain is relatively small, of about -12 dBi. Nevertheless, the obtained parameters are acceptable since the antenna is meant for near field communication application.

Abstract

Shrimp farming requires a touch that must be right on the side of water quality; water is a fundamental factor that must be met to achieve maximum yields. Many factors affect the quality of the water, but some things cause changes in water quality caused by external and internal factors causing death in shrimp. Disease conditions in shrimp can attack at any time, coupled with external factors such as extreme climate change, and cause changes in water components such as water pH, CaMg or hardness, and other factors that cause death in shrimp. Water turbidity oxygen demand (DO) in water determines the life of shrimp. It is coupled with microorganisms that must be maintained to maintain water quality for the growth of a Vaname shrimp. This research raises the Aquaculture System, specifically in the process of intelligent monitoring of water quality in shrimp nurseries to the shrimp harvest process, especially vaname shrimp from the results of observations use three sensors connected to LoRaWAN is able to provide real-time data from pond water and transmit it to LoRa Server or Internet Server, and the realtime data can be read through a Smartphone. This research analyzes in detail the ability of LoRaWAN to send multi-sensor data and Quality of Service LoRaWAN communication at different distances. This research also discusses how the LoRa antenna design can be developed to improve the performance of LoRa as transmitting devices or Radio Frequency 920-923 MHz for sending sensor data for Aquaculture.The contribution of this research is shown in the real-time monitoring system of the water environment, namely water pH, ammonia, turbidity, DO, salinity, water temperature, and nitrate in vaname shrimp ponds. The following contribution is the development of LoRaWAN with Tago IO servers capable of being used in Smart Aquaculture for contributions to The Things Network community or LoRaWAN Community.
