The results can be seen on the display control station on the GCS (Ground Control Station) system. To transmit data from the drone to the GCS, a good wireless network is required. To get a good wireless network, it is necessary to choose the right device. One of the important devices used in a network is a router. So knowledge about router performance is needed in order to determine a good router to be used on UAV and on GCS. The router that was tested for its performance in this study was the RB 3011 UiAS-RM with RB 450 Gx4. The tests were carried out using the no-load and with-load bandwidth testing methods using the traffic generator feature. From the test results, it can be concluded that the RB 3011 UiAS-RM and 450 Gx4 routers have performance that is not much different. This can be seen from the results of the no-load ...

Service quality is the most important factor and must always be maintained properly. The quality of service can change depending on the number and characteristics of service users. This study optimizes the performance of existing computer networks, namely ordinary LAN networks with the application of VLANs. It is very important because the number of network users is increasing and will continue to increase, while the need for good service quality is very urgent. The results showed that VLANs can improve computer network performance from the system existing, namely LAN network.

The optimal distance between nodes is obtained from the recording using the wireshark application. The linear regression method is used to build distance forecasting systems with packet loss and delay metrics. Observation is done by simulation using Network Simulator and direct measurement using wireshark. The results showed that the recommended optimal distance is 34 meters with a good category network quality.

In this study, a 5G network path loss planning was made using the Geometry Based Stochastic model. A forecasting system is created that connects the path loss with the distance between the transmitter and the receiver antenna using the linear regression method. It is important to look at 5G network planning on a different side. The result shows that the path loss value in the light of sight condition is better than the non-light of sight condition with the lowest value of 94.4271 dB at the frequency of 28 GHz and 99.5856 dB at the 73 GHz frequency. Linear Regression analysis shows that the best path loss calculation is the frequency 28 GHz of LOS conditions with MSE is 0.001 and the standard deviation error is 0.0319.

Some of them used mobile velocity and traffic congestion as variables in their observation. This research becomes very important because the writer of this paper was not sure of the result and the analysis of some previous research. So, this paper aims to explore about the impact of node velocity and traffic congestion to the performance and characteristic of AODV in MANET. The transport agents used are Transmission Control Protocol for File Transfer Protocol (TCP/FTP) and User Datagram Protocol for Constant Bit Rate (UDP/CBR). The research is applied by using Network Simulator 2 (NS-2). The performance is measured over some parameters, namely Overhead Routing (RO), Normalized Routing Load (NRL), and Packet Delivery Ratio (PDR). The contribution and the results obtained proved that the node velocity and traffic congestion can degrade the performance of AODV in MANET. It argued the other previous research claim that the node speed or velocity did not have influence to the performance of AODV MANET.

This system utilizes digital image processing as an identification process. By this system, it is expected that the identification results will be more accurate results than conventional monitoring, so as to increase the results of hatching. This system utilizes a flashlight as a medium, so that the egg's internal condition can be seen which then takes pictures by the webcam. After that the digital image processing is done by converting the original image (RGB) to binary image by providing a thresholding value (T), the T value is very influential in the next image processing, opening and closing, thinning the image (thinning), and contour detection. Then from the final process of contour detection produces the number of detection of blood vessels that are considered as embryos as a determina...

Almost in the coastal areas and islands in Madura are experiencing difficulties in utilizing marine resources. Salinity changes influenced by water osmotic pressure whereas biota living in salt water should be able to adjust the osmotic pressure from its environment. The changes in pH have an effect on the survival of marine organisms as not all saltwater creatures survive with the change of it. From these problems a system of "Designing Measure of Salt Measure and Sea Water pH Using Fuzzy Logic Based Android" is made. Where measuring system is made to prioritize the level of accuracy of changes in salinity and pH value of sea water. So that people could exploit the sea potential based on the condition of the sea water. The reading of sea water condition changes using salinity sensors, pH sensors, and MCU nodes as communication with android devices. Input from the sensor can be sent to the web server and received by android and then processed by fuzzy logic method to get the maximum output. The system can work according to what is expected during 5 days of testing in different locations. The success of this system is 97.3% with a 2.07% failure rate.

One of the efforts in planning process is forecasting. There are many methods in it, and this paper proposes to use Quadratic Equation Formula as a forecasting method. It is used because of the simplicity and it is suitable to solve problems with parabolic characteristic that can not be solved by linier computational method. It also compares characteristic of Quadratic Equation Formula with Linear Regresion forecasting.The result of this research shows that the computer network performance can be forecasted with Quadratic Equation Formula which has similar case characteristic with it. The standard deviation error of forecast value of the Quadratic Equation Formula is 370 of 3080 forecasted throughput maximum value. While the standard deviation error of forecast value of the linear regresion method is 282 of 3518 forecasted throughput maximum value. But in the forecasted throughput of linear regresion methhod, the output value will allways increase as the increasing of the input variable value. As the result, the error distribution calculation is not interesting anymore because there is no peak value for the forecasted result.

The system used PLL (Phase Loocked Loop) system on the oscillator. An oscillator is an electronic device that produces a voltage signal output. The use of oscillators as the carrier of the signal and the message signal produces waves with a certain frequency value, and has a frequency shift of 56,25KHz. The output of the FM receiver is a signal containing of the FM transmitter in the 88MHz-108MHz range. The signals received from the transmitter are short audio and sine signals, so they can be analyzed based on their waves in oscilloscopes and matlab experiments. In this trainer, there are tuners, IF amplifier, multiplexer demodulator, and digital counter frequency. The IC used is LA1260, LA3361, LB3500, LC7265. The result of making an FM receiver trainer get a satisfaction value of the practical test 80,12% based on aspects of media appearance, technical quality and usefulness.
