    An aerial vehicle has actuator four brushless DC motors (quadcopter) which is operated using a remote control or automatically. An aerial vehicle commonly called a quadcopter is controlled by using sensor data Inertia Measurement Unit (IMU) especially gyroscope and accelerometer sensor. Motion control is a stick control with sensor data IMU as data input. The motion from the aerial vehicle is a two-dimension (2D) motion from X axis and Y axis. Data sensor IMU is read by a microcontroller and will be processed to get real data acceleration (acceleration without influenced gravitation) remotely. The distance gesture inertia and the speed at which it operates are the parameter that is converted into an air vehicle motion. Trajectory motion is changed into picture domain 10x10 pixel as the comparison with the template matching algorithm. Match motion recognition is a motion command to the quadcopter. The simple motion like vertical, horizontal, diagonal, and curve match 96% using template matching algorithm and trajectory estimation

    Wireless Sensor Network or WSN is a collection of nodes in the form of sensors which establish a network wirelessly. The function of WSN is to collect scattered data that is obtained from sensors which will be transmitted via Ad-Hoc communication to Base Station for further processing. In implementing it, WSN has several problems that occur. One of the problems is the energy consumption and lifetime of the sensor node which the sensor node uses energy only from the battery for its operation. In fact, on its application, the data is not taken once. Thus, it needs energy savings to reduce energy consumption, and the amount of enough energy to make the sensor nodes has a longer lifetime. One of the solutions to overcome the problem is to design a protocol from WSN so that sensor nodes can transmit data to Base Station effectively. In this final project, the simulation was done using three protocols, namely Low Energy Adaptive Clustering Hierarchy (LEACH), Hybrid Energy Efficient Distribute (HEED), and Power-Efficient Gathering in Sensor Information Systems (PEGASIS). The LEACH and HEED protocols used clustering method while PEGASIS used chain method. The analysis performed on these three protocols was energy consumption and network lifespan using the same parameters of Zigbee Xbee Pro and simulated on Matlab R2013a

    Home electronic devices, such as lights, fans, and etcetera are now an inseparable part from the daily life of current society. However, these devices are often used in a wasteful manner. A room light, for example, is often still lit even though it is no longer used. Therefore, a home automation system that can help users to monitor and switch their electronic devices remotely through a user interface must be designed. This research resulted in the design of home automation systems using Wireless Sensor Networks (WSN) which were used to switch the electronic devices and communicate with the user interface. Communication between WSN and the user interface was regulated through the Message Queuing Telemetry Transport (MQTT) protocol. The results of this study were a design of home automation systems that can switch electronic devices remotely with an average delay performance of 0.509 seconds. The quality of the designed WSN was classified as "good" using the Telecommunications and Internet Protocol Harmonization Over Networks (TIPHON) standards, where the round-trip time (RTT) gateway with a latency value was 16.452 ms, jitter was 6.618 ms, and packet loss was 0%

    Low Power Wide Area Networks (LPWAN) applications are a major concern in infrastructure. Rural are areas that have a poor quality signal; the cause lies in the location of the rural regions away from the coverage area Base Transceiver Station (BTS) so that the need for telecommunications equipment in the form of Global System for Mobile communications (GSM) repeaters. GSM repeater devices require an antenna that has a large gain mainly on the receiving antenna, one antenna that has a large gain character is helix axial mode has a large dimension resembling a spring and has a directional radiation pattern properties, whereas the antenna with an omnidirectional radiation pattern is a patch meander line antenna has compact dimensions and is easy to fabricate. The meanderline patch antenna has the disadvantage one of which is the small gain caused by trapped surface waves on the ground. This research will discuss the design and realisation of helix axial mode, and patch meanderline Defected Ground Structure (DGS) for Low Power Wide Area Networks (LPWAN) application in a rural area so it can be used for Internet of Things (IoT) based weather monitoring. Integrating antenna helix axial mode as receiving antenna and antenna patch meanderline DGS as rebroadcast antenna in GSM repeater able to make edge network in a rural area become High-Speed Packet Access + (HSPA +) network. The test result IoT based obtained the value of Received Signal Strength (RSSI) an average of -89 dBm in HSPA+ network

    A license plate is one of the vehicle identities. It consists of alphabetic characters and numbers and representsprovincial and area code where the vehicle is registered. This article discusses the character recognition of platenumber using zoning and Freeman Chain Code (FCC). Zoning divides character image into several zones i.e. 4, 6,and 8, and then, the pattern of each character in the zone is extracted using FCC as the numerical features. Thecharacter is then classified using Support Vector Machines (SVM). It is a multi-class classification problem with 36categories. The results show that FCC features with 8 zones give the best accuracy (87%) when compared to theother two zones

The principle for fabricating the prototype of the electronic system based on the mechanism of handshaking system between electronic systems and line port for a printer. Program embedded on a personalcomputer with certain specifications for the operation of the system. The prototype of the electronic system consists of 3 (three) main subsystems, namely the diver circuit, sensor circuit, and the circuit of electrical installations analogy. Measuring against the prototype performance is carried out on the port line for the printer, driver circuit, sensor circuit, and electrical installation analogy circuit. The path performance on the port line for the printer is focused on high or low logic on each port. Data port condition is used to process data transmission, while the status and control port conditions are used to process data reception. The performance of the control circuit is very much determined by inputting data from the user so that it is closely related to the data port. The performance of the sensor circuit is very much determined by the condition of the electrical installation analogy, so it is closely related to the status and control ports. The performance of the circuit of electrical installation analogy is marked by the presence of a voltage value, and if the voltage measured in the electrical installation is 220 volts AC, then it is as an installation marker inactive condition. Overall the system is capable of 8 remote monitoring points so that the condition of the electrical power supply through the electrical panel can be monitored at any time

    The two-wheeled balancing robot is a robot that will maintain its balance to stay upright by using two wheels. This robot cannot be stable when the condition is upright and requires a control mechanism when moving. Thereare at least two control mechanisms in this robot, first is balance control, and the second is position control. The cascade PID method is proposed as a control mechanism, which consists of balance control as primary control and position control (distance and direction) as a secondary control. This method has been applied to robots. Based on the first, second, and third experiment, the best configuration of cascade PID control is PID for the balance control block, PD for distance control, and PD for direction control. By using cascade PID control, the two-wheeled balancing robot hasbeen able to balance itself with oscillations ranging from 15.00 degrees when moving and it can move towards the ordered position with the error position from the target. Fourth experiment position error is (0.17, -0.26) and (0.45, -0.43) for the fifth experiment
