Abstract

This paper analyzes the comparison of data communications using GEO satellites between C-band and Ka-band frequencies in Indonesia which has a tropical rain climate. The data communication uses QPSK modulation on the path of four earth stations by paying attention to six variations of observation time. Parameters, C/ N, Eb/No and link margins, are applied to indicate the communication performance. This study shows that C-band satellite communication can be implemented for all conditions, whereas in Ka-band the success of communication transfer cannot be accessed by all observation times.

Abstract

Automatic Identification System (AIS) is a ship transponder that uses MMSI data, speed, position, destination, ship type, and size to locate, track, and monitor ships. Only Vessel Traffic Services (VTS) and a few other agencies can be supervised presently. This is one of the issues that must be resolved. To resolve this issue, hardware that can receive AIS signals at 161.975 MHz and 162.025 MHz and convert them into information signals is required. RTL-SDR is hardware capable of receiving signals in the frequency range of 25-1700 MHz. Its antenna is used to achieve maximum signal reception by establishing a direct line of sight to the AIS data source. Yagi antennas can only receive signals from a single direction, the front. Low Noise Amplifier (LNA) is also used in order to optimize the signal received by the antenna. The signal can be processed and decoded using SDR-Sharp and AISMon to provide data that can be plotted on OpenCPN. The performance of the AIS data decoding process is controlled by the strength and weakness of the signal that the RTL-SDR receiver can receive. Therefore, the antenna and receiver must be placed in a clear line of sight (LOS) with the ship's AIS transponder emitting source. It is envisaged that this monitoring system would make it easier to monitor ships in real-time

Abstract

Nowadays, the use of renewable energy is increasing, especially distributed power generation (DG) connected to the power grid. There are several problems when DG is connected to the grid. The principal obstacle pertains to the detachment of Distributed Generation (DG) from the grid, a phenomenon well known as islanding. Islanding detection is an important task that should be completed in no more than two seconds. Earlier studies have shown several approaches to islanding detection. The use of an Artificial Neural Network (ANN) based on the learning vector quantization (LVQ) technique is proposed in this paper for fault classification and islanding detection in grid-connected distributed generators. The method consists of discrete wavelet transform (DWT), which extracts some features from the fault signal. Then, LVQ is used to classify the disturbance and detect islanding events. Power, entropy, and total harmonic distortion (THD) are used to obtain the total harmonic value. All features become inputs for LVQ, and system disturbances, lightning, and islanding disturbances are used as LVQ outputs. There are 600 datasets consisting of 200 datasets for each fault as training data. To test the LVQ training results, 120 datasets consisting of 40 datasets for each disturbance are used. The training error is made at 0.1 percent to get good testing results. The test results from 120 datasets showed that the test data achieved 99.10% accuracy. In other words, the test results are very effective because there are only 0.9% errors, and there are 2 test data that do not match the actual situation.

Abstract

The Araceae plants are highly popular among plant enthusiasts worldwide. The Araceae family has more than 100 different types and thousands of species. Despite ever-evolving times, these plants have a high market value and challenging breeding methods. To achieve optimal quality, it is important to maintain the appropriate humidity and temperature according to the natural conditions of these plants in the tropical rainforest. The Node MCU ESP32 is a processor for instructions from the room temperature sensor, room humidity sensor, and soil moisture sensor. Additionally, this component controls the blower and misting system as output, which will be processed through LoRa technology to transmit monitoring data to the Blynk software. This study utilizes fuzzy logic to categorize room temperature, humidity, soil moisture, and output results for different Araceae plants. LoRa technology is used to send monitoring data efficiently in the data transmission process. During data retrieval using long-range technology, a delay of approximately 5 seconds is known between the receiver and transmitter at a distance of 700 meters. Constraints that cause issues with this long-range technology are influenced by wind, which affects antenna signal strength, and the presence of trees and buildings as obstacles. The monitoring results show an average temperature in normal conditions and an average humidity in wet conditions. At the same time, soil moisture is monitored to maintain normal humidity, resulting in all outputs being off.

Abstract

Penelitian ini mengembangkan metode pendeteksian penyakit TB paru dengan komputer menggunakan ciri statistis histogram citra sinar-X digital. Pendeteksian meliputi pra-proses ekualisasi histogram, proses segmentasi citra dengan pengambilan area paru berdasar ROI template, ekstraksi ciri statistis histogram citra dengan metode PCA (Principle Componen Analysis), dan klasifikasi dengan minimum distance clasifier. Uji coba memperlihatkan metode histogram ekualisasi dan penggunaan ROI template yang tepat memberi kontribusi positif dalam kalkulasi ciri statistis histogram citra. Penerapan tranformasi PCA dalam ekstraksi ciri dan dikombinasikan dengan fungsi pengklasifikasi minimum distance classifier memperlihatkan hasil uji pendeteksian yang cukup baik. Pada uji coba dengan data citra uji primer, pada penggunaan jarak Mahalanobis akurasi pendeteksian mencapai 95,455%, sedangkan pada penggunaan jarak Euclidean, dengan akurasi mencapai 94,318%. Meskipun demikian, hasil uji coba penerapan metoda ini pada data citra sekunder tidak memperlihatkan akurasi sebaik pada penerapan pada data citra primer. Kondisi data citra sekunder berbeda dengan citra primer menjadi penyebab perbedaan akurasi tersebut, dan menjadi peluang penelitian lanjutan untuk mengatasi perbedaan tersebut. .Kata-kata kunci: TB paru, citra sinar-X, ciri statistik

Abstract

There is no denying that wireless communication technology is a very important component of modern society. One aspect of modern society where the application of wireless communication technology has tremendous potential is in an emergency. This is especially true in weak places and cannot be reached at all by cellular signals. A good example would be the application of wireless communication technology to transmit data about the emergency button is mountained. Nowadays in the mountain all those things can happen when the moment, the champion can experience, hurt, or sick in the middle. Therefore, our goal in this study is to develop and test an affordable wireless communication system for the swimming state center when performing applications. The system uses microcontrollers and communication systems that use Arduino and LoRa as Transceivers and Receivers. The system was successfully tested in the field and obtained data with a distance of 1.2 Km.
