<![CDATA[The development of wireless technology is very rapid in line with the needs of users for high-speed, efficient, reliable and quality communication systems. One of the technologies favored by telecommunication service users is Wireless Fidelity (WiFi) which is already supported byMIMO technology. Multiple Input Multiple Output (MIMO) is a system consisting of more than one terminal or antenna on the transmitter and receiver sides. With the use of more than one antenna, MIMO supports transmission media specifications that require a large capacity in the communication system. This research discusses the design and realization of the MIMO 4x4 microstrip circular patch antenna that can work on the 2.4 GHz frequency band for WiFi technology applications. The inset feed method is used to get the impedance value that matches between the patch and the line. To increase gain, a linear array method is used for each antenna. Testing the effect of the distance between antennas on the mutual coupling value. As well as testing the signal strength performance of the antenna if implemented as an antenna device at the access point. The results of the MIMO 4x4 test results Circular Microstrip Patch show the value of Return Loss = -13.3 dB; Mutual Coupling = -39.3 dB; VSWR = 1.482; Signal Strength = -25 dB.]]>

<![CDATA[Giving intravenous fluids is very useful to support and accelerate the recovery of the patient's condition during the healing period. Problems in handling can have a negative impact on patients who are currently monitoring intravenous fluids using a manual system. To reduce the adverse effects on patients is to design an arduino-based intravenous fluid monitoring tool. The design of this tool is a way of monitoring that can be done at a distance. This tool aims to provide a warning when the intravenous fluid will run out (Â ± 100 ml) using a weight sensor, detect the drip stop using the ldr sensor and detect the intravenous entering the infusion tube using a photodiode. The value obtained from a sensor will be received by Arduino NodeMCU . Then Arduino will send the value which goes to the database then from the database it will enter the web monitoring. Where the web monitoring is in the nurse's room which monitors intravenous fluids remotely. The data from the heavy sensor has 95% accuracy because the data obtained is not affected by conditions from outside the sensor, while the photodiode and LDR data have 90% accuracy because these two sensors are light sensors that can be affected by light from outside.]]>

<![CDATA[Mangrove forests have high ecological, economic and social values ??which function to maintain shoreline stability, protect beaches and riverbanks, filter and remediate waste, and to withstand floods and waves. The facts show that mangrove damage is everywhere, even the intensity of damage and its area tends to increase significantly. Many roles of mangroves require proper management to maintain the existence of mangroves. One way to determine the area of ??mangroves is by processing Landsat 8 satellite imagery. The stages of mangrove identification are carried out by using 564 RGB band merger, then separating the mangrove and non-mangrove objects. Next step is to analyze the density of mangroves using NDVI formula. To maximize monitoring of mangrove area, an android application was created that provides information on the area and density of mangroves at several locations, namely Clungup, Bangsong Teluk Asmara and Cengkrong from 2015 to 2018.The results showed that Landsat 8 satellite imagery can be used to identify changes in the area of ??mangrove forests with good accuracy, namely in the Clungup area of ??90% and Cengkrong of 86.67%. From processing results, the mangrove area in the Clungup area has also decreased from 2015 to 2017 but has increased in 2018 so that the application provides recommendations for embroidering mangroves in 2016 to 2017 and mangrove recommendations are maintained in 2018. As for Bangsong Teluk area Asmara and Cengkrong have increased the area of ??mangroves every year so that the application provides recommendations to be maintained from 2016 to 2018.]]>

<![CDATA[In this study, the authors built a website that can be used to stream video both realtime and On Demand using software specifically for streaming, namely DaCast and OBS Studio. The purpose of this livestreaming website is made because the video streaming system is broadcast, so we don't need to come to see something we want, because what is displayed is exactly the same as what was in the original, unless there are some video streaming problems, unless there are some problems such as in network performance or quality. This problem can be overcome by analyzing the quality of the network or what is called Quality Of Services (QoS) using the Wireshark application. QoS aims to help users be more productive by ensuring that users get reliable performance from network-based applications. The author analyzes the QoS of the website that has been made based on the parameters of Delay, Throughput and Packet Loss for 7 days, which are differentiated by working days and holidays, which are in the Malang State Polytechnic campus area with variations in the morning, afternoon and evening. Live Streaming test results on QoS parameters obtained are average delay on the 3G network is 119.6 ms and the 4G is 54.4 ms, the average throughput on the 3G network is 925 Kbps and 4G is 1496 Kbps, the average packet loss on 3G network is 11.3% ms and 4G is 27.27%]]>

<![CDATA[Currently, public transportation is needed by Indonesian people to meet human needs for increased movement or mobility. Along with the increasing public interest in trains demanding an increase in services such as the checking system for passenger tickets still using manual system by officers by approaching passengers in each car. This is'nt efficient, so an automatic passenger ticket inspection system using RFID is required. Passenger RFID is scanned when check-in at station then the data is sent to server via nodeMCU ESP8266, the officer only checks passengers through the data display on the monitor. This system also has a Flex sensor in each seat which functions to detect seats that aren't purchased but are occupied by other passengers.The test results concluded that the reading of the RFID card against RFID reader reached distance and barrier with a thickness of 3cm, the DHT11 temperature sensor showed reading accuracy up to 96.6%, and the voltage on the flex sensor on seat 1 had average load of 2.6V, seat 2 average 2.82V, seat 3 averaged 2.84V, seat 4 averaged 2.67V, while the voltage on the flex sensor in seat 1 had an average load of 2.38V, seat 2 averaged 2.29V , seat 3 averages 2.65V, seat 4 averages 2.60V. The value of the flex sensor tension in each condition isn't the same for each seat because the surface shape and thickness of each chair are different. All systems can run properly, starting from sensor readings, transmitting data and displaying data on web.]]>
