Abstract

In this research, Authors make a monitoring system of dangerous gas content in the chicken coop. The system able to inform air quality in the form of ammonia and methane gas contained in chicken coop and give result of reading of gas data which considered dangerous to worker in chicken coop and can be seen by platform. The system generally consists of two gas sensors, the MQ 135 sensor to detect the ammonia, and the MQ 4 sensor to detect methane, and connect to the internet network via the ESP8266 modul with Arduino Uno microcontroller that aims to upload sensor data to web Thingspeak and displayed in the form of graphs as a means of information on the chicken coop. Testing was did with 3 stages of connectivity, functionality, and delay. The connectivity test proves that the ESP8266 can connect to the Access Point and Internet network. The functionality test proves that the sensor can read the gas and retrieve the data. And the last is the delay test, which is calculating the length of the process from the beginning of the sensor readings until the data arrived at IoT web based Thingspeak. From the results of calculations that have been done in testing, it is found that the time required for a single data transmission takes as much as 5-19 seconds. The time may change because there are aspects that can hamper such as internet connection, the number of devices connected to one network internet, but the purpose of research is in accordance with expectation.

Abstract

Orchid is one of the most favored plants. Orchid is one of the most widely exported ornamental plants in Indonesia. In the cultivation of orchids, monitoring the state of the plant is important. Parameters - parameters that need to be monitored include: humidity, temperature, and light intensity. These parameters greatly affect plant growth. Plants can grow well if moisture, temperature, light intensity are well . A good orchid moisture ranges from 60 - 80%. Humidity should not be too high during the night and should not be too low during the day. In addition to humidity, the temperature of the orchid plants should be in the range. The ideal temperature for orchids is: daytime temperature between 27-30 degrees Celsius and night temperature between 21-24 degrees Celsius. Based on these problems, the Moisture Monitoring System, Temperature, Light Intensity on Orchid Plant using ESP8266 and Arduino Nano are designed. In this design, the result of sensor readings will be displayed in graphical form and Chart on IoT Thingsboard. To reading moisture, temperature, light intensity used several sensors they are: LDR, Soil Sensor and DHT-11. From the results of implementation and testing can be concluded that this system can display all the readings of the sensor, and run the system automatically well. The average execution delay is 0.622 seconds and delivery delay is 1.468 seconds.

Abstract

Fault tolerance is the ability of the system to be able to continue running even when it is damaged. Fault tolerance has several types that are often used, in this study will be discussed about TMR (Triple Modular Redundancy). TMR is a hardware redundancy technique that duplicates 3 computing modules, and there will also be a voter polling the computational module. The voter's job is to see if any of the computing modules are damaged. However, in this study, the TMR voter will also be triplicated to reduce the possibility of a single point of failure, namely the event that the system cannot function if one of the modules is damaged, in this case is the voter. The device used as a computing module in this study is Arduino Uno, this study also uses the FC-37 rain sensor as an experimental sensor to retrieve the data. The result of this research is that the reliability value of the Triple Modular Redundancy system with Triplicated Voting is 98.49%, which is an increase compared to Triple Modular Redundancy with only 1 voter, which is 92.74%. The success rate of experiments conducted on Triple Modular Redundancy with Triplicated Voting also generally increased.

Abstract

The heart is a vital organ that pumps blood throughout the body. A healthy heart beats neither too fast nor too slow, normally 60-100 times per minute. A heart that beats too fast up to 120-300 times a minute is called tachycardia. Ventricular tachycardia (VT) is a tachycardia that occurs in the ventricles if it lasts for a long time, can lead to congestive heart failure and death. Deaths caused by heart and blood vessels are in the highest rank in the category of non-communicable diseases, based on The Institute for Health Metrics and Evaluation (IHME). To prevent an increase in deaths from heart disease, the public is expected to be vigilant by checking their heart health from an early age. Cardiac examinations can only be done at health care service, therefore the aim of this study is to build a system that can detect VT that can be done alone anywhere. To build the system, the AD8232 module is used as a signal conditioner and Arduino Uno as a microcontroller. VT heart defects can be seen from the shape of the QRS signal and the rate of the heartbeat. The parameters to be used are the RR interval and the area under QRS. The classification method uses k-NN because this method is suitable if only a few parameters and data are used. From the research results obtained 90,47% accuracy for k = 3 and k = 5, 95,23% for k = 7.
