Abstract

Server room is a room used to store server computers, network equipment such as routers, server computers and other important equipment. This server room requires special attention to protect the equipment in it, such as temperature, humidity, fire and other disasters. Therefore, in this study it is proposed to implement a server room monitoring system with the modbus interconnection protocol to measure temperature, humidity, vibration and electric current conditions in the server room. The system uses 1 master to display data and provide warnings and 2 slaves paired with sensors. The system is connected via the RS485 module and data transmission uses Modbus RTU. In addition, the system uses a master-slave which uses Wemos D1 mini on the master and Arduino Nano on the slave connected to the DHT11, SW420 and SCT-013-00 sensors. The results of this study are that the system as a whole can monitor the server room via LCD16x2 and Telegram and the system can provide warnings when room conditions are abnormal in the form of alarms with minor, major and critical levels as well as warning notifications to Telegram when in predetermined conditions. The system can send sensor data from slave to master with a cable length of 5 meters for slave 2 and 4 meters for slave 1. At a timeout value of 3574ms the system has an average time interval for sending data from slave 1 which is 196.4ms and from slave 2 which is 598.5ms with data read by the master having a length of 13-14 data.

In this case watering has an important role to help humans in caring for plants so that plants can grow properly, as well as the system sometimes can be failed this can make plants unable to grow properly. This failure can be reduced by implementing a fault tolerant system with hardware redundancy techniques in which the use of hardware redundancy makes a system have additional modules to minimize system failures. N-modular with spare is a hardware redundancy technique, This technique makes a system have a spare module where this module works to minimize system failure. In this system the microcontroller retrieves data from the capacitive soil moisture sensor using I2C, the data is forwarded to the voter. Voters will do majority voting where the voting results will be forwarded to the Disagreement Detector. The disagreement detector has the role of turning off the spare module, the active module and turning on the spare module. The module is deactivated when the data retrieved by the module does not match the other modules. The system can keep running as long as the module does not exceed the error limit of the system design. From the research, the system has successfully run according to the wishes of the testers and the system has been able to perform fault masking, detection and location and recovery. When the system was added using the n-modular with spare system, the reliability increased by 5.72% from 92.7% to 98.42%.

Abstract

Mobile Ad-Hoc Network (MANET) is one of the example of technology development in networking. In MANET there are nodes that has mobility and communicate with each other through wireless network. In order to communicate in MANET, there need to be routing protocol that can be used, and the most commonly used is Ad-Hoc on Demand Distance Vector (AODV). And live up to its name, AODV is a protocol that has a dynamic topology, and it fits right in for MANET conditions. Therefore, with those conditions, there's a need to conduct study if number and mobility of nodes will affect performance of AODV in MANET. This study aims to understand and analyze the performance of AODV in MANET if there's a change in number and mobility of nodes. On this study there will be 2 categories of special scenarios will also be conducted with difference in number of nodes and node speed. So the special scenarios are 2 node and 10 nodes with (20, 40, 60, 80, 100 m/s) for the speed of nodes. Through this study, the results are adding number of nodes from 2 to 10 nodes definitely affected the performance of AODV. The scenarios with 2 nodes show better results than the 10 nodes ones, because with more nodes it takes more time to find the route for sending packets. And with speed variation, it also affected the performance, as the faster the nodes, the harder it becomes to find a route with stability, as it shows on packet delivery ratio that keeps dropping.

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.
