Abstract

Monitoring and watering have an important role in managing mushroom plants. However, the measurement used is the use of a thermometer as a manual and watering device. Through these fundamentals, it is conducting monitoring and automation of the fungal watering system with fuzzy logic method. The first process is to get information from the DHT11 sensor to send sensor data to the microcontroller for the process of output and humidity, the results of the data can be seen on the LCD screen. Blynk application is done as a remote monitoring. Fuzzy logic method was chosen to category the problem of input data to output data in conducting clean watering. From the sensor test the results obtained compared to the DHT11 reading sensor had an average error of 4.07%. In the process of watering the control system carried out as many as 10 times with a percentage error of 16.66%. Comparison of test duration has a difference of 45 seconds and the difference in water released by 500 ml. Although there are many more manual resections and long durations, the accuracy of the sensors and controllers with fuzzy logic method is more in line with the conditions needed in the mushroom place.

Abstract

The Internet of Things is the interconnection of various devices over the internet, allowing these devices to communicate with one another. The diversity of requirements and format of data from devices in IoT might cause problems in the aspect of interoperability. The integration of IoT with Web of Things (WoT) can serve as a solution so that users can access devices in IoT through the same source. One technology that is easier to implement using IoT and WoT is Smart Home (home automation). In Smart Home there are devices like sensors and microcontrollers with limited resources, therefore the MQTT protocol is used as a support for communication. WebSocket, as a WoT protocol, is used as a communication protocol so that the controlling and monitoring system Smart Home can run in real time. To support the system to remain safe in the exchange of data and in the management of devices connected to the system, JSON Web Tokens are also used. Based on the results of implementation and testing, it is evident that the system has a delay of 1 millisecond, while the most optimal response time is when the NodeMCU sends 10 data at a time to a server that only takes 1 second. In addition, LED actuator devices and fans can function properly according to orders obtained from users through a web application.

Abstract

Nowadays food is no longer just a basic necessity, but food has been used as an entertainment. As can be seen on social media, there a lots of photos of foods that attract our attention, thus force us to cook and made the food. To make food, a food recipe is needed. In general, food recipes can be found in magazines, television, newspaper, and websites. The recipe is searched by the name of the dish. The limitation of knowledge obout food's name, makes it difficult to find the recipes. By seeing this problem, we can use Content Based Image Retrieval (CBIR) to make the image as the query. Searching by using an image we need digital image processing to obtain the features of the image. The used features are red, green, and blue (RGB) color channel as the color feature, simple morphological shape descriptors as the shape feature, and k-NN as the classification method. The result of this research give the best n value n=5 where mean average precision (MAP) is 94,1892% on the combination of color and shape feature. The use of color and shape feature commonly obtain the best result on the combination of the both feature at n=10, n=15, n=20, dan n=25. The conclusion is when the higher value of n give the worst result of MAP and the use the combination of color and shape features can provide the best results compared using of one feature.

Abstract

Fires occur not knowing the place and time, can occur anywhere and anytime. Some causes of fires are human error, electrical short circuit, cigarettes, stove etc. Related to many parties who replace losses with property, business entities, and casualties. Based on these problems, we need a system that can overcome fire problems and take preventive measures such as blackouts. In previous studies it could only be called monitoring in information or it could be called monitoring. In this study the parameters used are the DHT11 temperature sensor, the sensor as soon as possible MQ-2 and the on sensor. The output of the system is an action consisting of an actuator with an exhaust fan for immediate transfer and water pump for fire suppression. The Fuzzy Mamdani method is applied to the system to connect the determinant of fan and pump actuators as needed. There are 3 input variables used, namely temperature with 3 membership functions, as soon as possible with 3 membership functions, and fire with 4 membership functions and 2 output variables, namely exhaust fan with 4 membership functions and water pump with 4 membership functions. Must get 36 fuzzy rules. From the test results, the system can determine various conditions of the room with accuracy reaching 100%. In fuzzy testing, the percentage of success is 100%. This shows that the results of the fuzzy testing method on the system are in accordance with the design that has been made. The system output determines the output that is an actuator, which is fan speed and pump duration varies.
