Abstract

Wireless energy transfer technology has enormous potential, in the field of transportation, for example, to charge a running vehicle. Many variables can affect the efficiency of energy transfer that occurs, one of the discussions in previous research by Akbar, S., et. al. (2021) regarding wireless power transfer, namely the effect of entering the frequency value on the value of the power transferred through a particular wireless power transfer circuit. In this study a frequency generator is made to output a signal that can be used in a wireless power transfer circuit. This research discusses the engineering of the generator frequency using a microcontroller, to produce a PWM signal with a certain frequency, and an IRF3205 Dual Motor MOSFET H-bridge to convert it into an AC signal. The engineered system also uses button and screen interaction with the user as well as monitoring the power drawn by the WPT circuit with the sensor. Based on testing, the system has succeeded in delivering energy and the effects can also be seen at different frequencies. For the output of the system itself, there is an average frequency error value of 0.27% and a maximum error value of 1.01% at a frequency of 121kHz.

Abstract

The use of relative positioning systems has become popular in an era where network devices are used to find the location of objects or people, especially in environments that are not connected to the internet network. The use of the Global Positioning System (GPS) is indeed very helpful when the system environment has a connection to the internet. So as a solution to overcome this, to find the position of the object at a predetermined location, a relative positioning system can be used using the Bluetooth Low Energy (BLE) protocol by utilizing the Received Signal Strength Indicator (RSSI) from the device. In determining the location of the vehicle in the parking lot using the trilateration method by utilizing BLE beacons which are used as reference points that have been determined at certain locations on the location plan that act as anchor nodes. The device whose role is to capture RSSI data from each anchor node is the sensor node. Then the data owned by the sensor node is sent to the sink node to calculate the estimated distance and trilateration calculations to find out the coordinates of the location sought. The resulting coordinates are then grouped according to the division of the parking lot location plan. Based on the tests that have been carried out, the calculation of the trilateration method to find the location of objects in the parking lot has an average percentage error of 31% and an average computation time of 3.24 seconds.

Abstract

Hydroponics is one of today's modern farming methods that can be done on limited land. Hydroponics is a farming method without using soil as a medium but using water. One of the main factors for the success of hydroponic farming is controlling the conditions of the growing media, in which the growing medium is water. Temperature and pH are parameters that can be controlled to ensure successful farming with the hydroponic method. Currently, the way to control the temperature and pH values of water is usually done by manual monitoring every day. This method is considered very impractical. Therefore, innovation is needed in the field of technology that can monitor and automate the pH value and water temperature. In this research, a prototype system was created that can perform this function using the Internet of Things method assisted by an Android application as output. This system uses ESP8266 as the main processor to measure temperature and pH values and automate pH values using a 12-volt DC pump and 5-volt submersible pump as well as automate temperature values using a DC fan in the hydroponic system. The accuracy of reading the temperature and pH values obtained by the system is quite high, namely 96.58% for the pH sensor and 99.61% for the temperature sensor. The android application that was created can run well and the system prototype was also successful in automating the hydroponic system's pH and water values.

Abstract

Waiters in restaurants often experience problems where the waiter sometimes does not hear customer orders properly so that errors occur in ordering, or problems where the waiter also does not hear when a customer calls the waiters. Therefore, service providers must improve services so that businesses can run optimally. One solution that can be done is take advantage of technological systems that were created to help overcome existing problems, is the use of an ESP-NOW-based communication protocol system. Therefore, in this study, a waiter calling system was created to be implemented a restaurant by implementing the ESP-NOW communication protocol technology. From the results of this study it is known that the use of ESP32 and ESP8266 can be considered efficient in terms of power usage because the test results obtained power consumption data with an average of 0.1087W for ESP8266 and 0.6932W for ESP32. The cost of assembling a complete set of ESP-NOW-based terminal systems is very affordable, namely Rp. 671,980, when compared to using a smart tablet device with an estimated cost of Rp. 24,440,000. The use of ESP32 and ESP8266 paired with the ESP-Now communication protocol is suitable as a low-cost, low-energy alternative for restaurant information system devices because it has low latency. The prototype used in this study was sufficient for the requirements specified at the beginning of the study.

Abstract

In research using Internet of Things, there is one component that uses the Wireless Sensor Network. In implementing on WSN, regular firmware update are needed to fix bug, security update and other problems. One of the obstacles when carrying out the firmware update process is if the system is implemented in a remote location such as being outside the city, it will take more time and effort to be able to update the firmware. By using the Over The Air firmware update method, users can update the system without need to go to the device location. However, there are WSN modules that cannot directly connect to the internet. Therefore, a gateway is used to bridge the process of sending firmware update using Bluetooth Low Energy. When an update is needed, the user will update the firmware via a computer or laptop that is connected to the internet. The data will be stored on firebase and will be downloaded by gateway. The gateway used uses the RaspberryPi 3 model B+ microcontroller. After the data is downloaded, it will be sent to the node named ESP32 microcontroller using BLE. Test were carried out to test the long delivery time using BLE based on the size of the data and the distance between the gateway and the ESP32 node. Fore sending 227 kB data sent at a distance of 5 meters it takes an average of 29 minutes 52 seconds and for 954 kB data sent at a distance of 5 meters it takes an average time of 1 hour 57 minutes 30 seconds. Because the BLE delivery is done per Byte so it will be sent one by one.

Abstract

Controlling the air quality of strawberry plants in a smart greenhouse prototype must be of great concern to strawberry farmers in order to get maximum yields. Air quality parameters that must be monitored, for example, are air temperature and air humidity as parameters that can affect the viability of strawberry plants. Given these problems, there is a need for research related to a system that can help answer these problems, namely the Smart Green House Prototype Control and Monitoring System on Strawberry Plants Using Fuzzy Logic Based on the Cayenne Application. The method used is the Mamdani fuzzy model to assist the control system in controlling air quality parameters in the smart greenhouse prototype, namely temperature and humidity parameters. The microcontroller used is Wemos D1R2 which can connect to the wifi network and can connect to Cayenne so that it can be monitored via Cayenne. The temperature and humidity sensor used is the DHT 22 sensor and based on the results of the test, it is obtained an error value range of 20,75% for temperature, while for humidity the DHT 22 sensor produces an error value of 18,7%. The test was carried out nine times in three conditions, namely cold, normal, hot for temperature and low, normal, high for humidity. The smart greenhouse prototype was also tested how effective the system is in controlling the environment by conducting experiments using actuators and without actuators. The results obtained from testing using the actuator, the temperature inside the smartgreenhouse can decrease by 2.13°C and humidity can increase by 5.1%. The second test was carried out without an actuator, so the temperature rose by 9.82°C and the humidity decreased by 22.16%.

Abstract

To determine the tempo in a song, Metronome is needed to help as a tool, because the metronome will produce sound on every beat of the song. However, the metronome used on the market is less effective in terms of helping the tempo during live shows and can also interfere with hearing when using earphones if the volume of the metronome should be increased. A metronome arm band can be a solution because it produces a vibration that can be felt in the hands. Users can also set the desired number of beats per minute (BPM) via a smartphone application that is connected via bluetooth. There are 3 elements to be used, which are; Smartphone as input, ESP32 as processor and Vibration Motor as an output. Because metronomes must have high accuracy in keeping the tempo, RTOS is needed to help avoid interruptions when the user sends other commands during vibration. There are 3 tests carried out to determine the accuracy of the Metronome Bracelet. The first test to see whether 60 bpm on the metronome produces an output of exactly 60 beats per minute. The second and third tests are also the same but at different tempo numbers, which are 90 and 120. The expected output of the metronome should be exactly like the number shown in the bpm value on the Metronome Bracelet, where 60 produces a vibration accuracy of 60 bpm, 90 produces 90 bpm, and 120 produces 120 bpm.

Abstract

One of the factors that affect quality of broiler chicken is its coop environment condition. Farmers need to maintain optimum coop environment by maintaining temperature at 20-25°C, humidity in the range of 50-70%, and ammonia concentration at 0-5ppm. These problems can be overcome by system that monitors coop environment, so farmers can take the necessary action to maintaining it. The size of the cage, which is quite large, is a blockage for system implementation. Based on these reasons, implementation of WSN can meet the requirements while increasing the flexibility of the system. But, WSN system has some deficiency, such as complicated and time-consuming configurations. Therefore, implementation of pervasive computation into the system going to reduce human intervention and time used for system configuration. Chosen pervasive computation is a sensor node that can identify other nodes and connecting each other to system network. ESP8266 is used to process the data and deliver it using wireless. Output of the system is a website. From the test result, node capability to identify other nodes with average of 56.67% at four locations. While to connect with WiFi network at a distance level 3 to 4 meter, 8 to 10 meter, and 15 to 18 meters, node time to connect averaging at 48.8575 second. At same distance level, service discovery found the system with successful rate average at 73.33%
