Abstract

River flood can happen when the river's water overflowed. Because of the dangers this flood brings, we need a system to monitor the river's water level. This system can be implemented using microcontroller and using Internet of things to connect the system to the internet, so the user can monitor the river's condition easily. This system use ultrasonic sensor to measure water level. But, sometimes, sensor can be prone to error. To make up for this, we use time redundancy algorithm. Time redundancy is repeating sensor sensing multiple times to make up for any error that can happen. Time redundancy is used to measure water level in a corrugated water because in corrugated water, water level can raise up and down which will affect the measurement, and time redundancy can sense the water level multiple times in a different time. Those data then will be averaged to get the true water level, which is assumed when the water is still. Using time redundancy to measure water level in corrugated water has an accuracy of 93.87%. Testing the performance of UDP protocol, author found the implemented UDP protocol has 100% success ratio and transmission delay of 3136.93 microseconds.

Abstract

The development of the internet of things occurs because of the Wireless Sensor Network. NRF24l01 is one of the communication modules used in the Wireless Sensor Network. The NRF24l01 communication range is suitable for use in homes and building. NRF24l01 can be implemented in daily activities for example turning off and on lamp. Sometimes there are lamp that are not installed in the lamp fitting and it is unknown when going to turn on the lamp. With this research, slave nodes are made as a driving force to turn on or off the lamp and use electric and infrared current sensors to find out whether there are lamp and nodes sink/gateways that connect the slave nodes to the smartphone application. Communication between slave node and sink/gateway node uses NRF24l01. Communication between sink/gateway node and smartphone application uses the concept of internet of things by using the MQTT protocol to manage its communication and cloudMQTT as a broker that stores data temporarily from these communications. This research uses a plug and play method that is applied when it is first turned on, the slave node will send an introduction to the sink/gateway node to get the address and the sink/gateway node will send the available address. The test results prove that the distance between the slave node and the sink/gateway node affects the delay of sending data, then the reference whether there is a lamp or not is the change in electric current and infrared sensors that detect objects.

Abstract

Wireless Sensor Network is a wireless technology required for monitoring environmental conditions which consist of several sensor nodes that can communicate and process information with each other. The problem in WSN is about power consumption which results in power at the node using only batteries for its operation, resulting in limited energy reserves. When one node dies, it results in a change in performance, there is an obstacle in having to conserve power energy repeatedly and reduce the benefits of WSN. The solution to this problem is to implement the Priority Scheduling algorithm to be placed on each node which will prioritize the order based on the largest to the smallest power. In the power monitoring mechanism of each node, NRF24L01 is available for sending and receiving data, Arduino Uno R3 microcontroller, ACS712-30A current sensor, voltage sensor, DHT11, and RTC DS1307 which functions to display real-time data results. Based on the test results, DHT11 accuracy is 98.52% to 99.26%, voltage accuracy is 99.6%, and the current accuracy is 94.86% to 97.86%. Data reception performance takes an average of 2 to 3 seconds. Retrieval of power data using Priority Scheduling in the room there are obstacles and no obstacles have a 100% success percentage obtained by looking at the results of the power data displayed on 10 experiments in different rooms and the order is according to the largest to the smallest power data.

Abstract

Floods is one of the most common natural disasters in the Asian region. Based on statistical data of the National Disaster Management Agency (BNPB) on 2009-2018, it was noted that the number of dead and missing victims over 11 thousand people. A monitoring system is needed that can quickly and accurately provide information and warnings to the public. Therefore, the researchers conducted a study entitled the development of a water canal monitoring system as a flood mitigation. To realize a monitoring system, a protocol for network communication is required. Hypertext Transfer Protocol (HTTP) is a protocol that allows communication between the ESP8266 which uses a client and server architecture with centralized control. HTTP POST request-response method can be used for the communication method between WiFi client nodes and WiFi server nodes. The system stores sensor data in a Firebase database connected to the android application. The android application can provide notification alerts to the user if the system detects a danger. Based on the test results, it was concluded that NodeMCU ESP8266 can communicate with each other using the HTTP POST method. From the sensor test, the average error result is 17.86%. In testing the delay of sending data between nodes at a distance of 5m, 30m, 50m, 80m and 100m, it has an average delay of 242.17ms, 964.4ms, 979.3ms, 988.9ms and 997.0ms. In testing the android application the system can display the results of system monitoring and the user gets a warning notification when the system detects a potential hazard.

Abstract

The use of electricity is a basic requirement for humans today, therefore it is necessary to have savings in its use so that lower costs and the supply of electrical energy in an area can be saved for something unexpected. Internet of Things is a device or system that is connected and communicates in an internet network. By using IoT, we can carry out a long distance communication which makes the performance of a system more effective and efficient. The communication module that is quite popular in IoT is Bluetooth Low Energy (BLE), but in BLE there are still drawbacks, namely the inability to connect to the internet so that a gateway is needed to communicate with the cloud server. This study aims to design an electrical energy saving system. The results of this study indicate that the system can work well. The delay obtained from sending data at the gateway to the Blynk Cloud Server has an average delay of 1,930 s with a jitter of 0.754 s, the average delay from the sensor node to the gateway is 0.672 s. The next test used a variation scenario of 1 meter - 11 meter distance with uccess ratio parameter. The highest success ratio is 90% at a distance of 1 meter and the lowest success ratio is 0% at a distance of 11 meters. The saving of electrical energy is up to 59.04%.

Abstract

Wireless Sensor Network (WSN) consists of a number of small sensor nodes that are used to observe a phenomenon. Generally, a wireless sensor network is a sensor device that is connected to an embedded system or called an embedded sensor that can connect to the network and communicate with cloud servers. The device commonly used in WSN is ESP-32, which has BLE and Wi-Fi communication on a single frequency. The use of sending and receiving data at a single frequency allows the collision of sending and receiving signals that cause packet damage. This can be minimized by implementing an appropriate scheduling method. One of the scheduling methods commonly used is Time Division Duplex (TDD). The concept of TDD is to divide one frequency into several time slots, and then time slots will be allocated for receiving or sending data. Previous studies have successfully implemented TDD on large-scale mobile networks with 5G technology and implemented BLE for blood pressure monitoring. This study aims to design a gateway with TDD scheduling method. The test is carried out with a scenario of distance variation with parameters success ratio, discovery time, and delay. The variation in distance used is 1 meter to 13 meters. The success ratio parameter produces a success ratio of 84% at a distance of 1 meter and 0% at a distance of 13 meters. Then, the discovery time parameter obtained 2.36 seconds at a distance of 1 meter and 2.73 seconds at a distance of 10 meters. Finally, the delay parameters obtained an average delay of 1 second at a distance of 1 meter and 7.68 seconds at a distance of 10 meters.
