<![CDATA[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%.]]>

<![CDATA[Face detection and tracking are one of the areas which always in progress in many applications such as security system, biometric and so on. However, face detection and tracking can become a complex problem when it is done in real time condition. Many problems are appeared such as dependency the detection result to lightness and diversity of background colour. In this article, we presented a new method to overcome the above problems by using the HSL colour filter (Hue, Saturation, Luminance) combined with the particle filter algorithm. The HSL colour filter detected face based on skin colour with adjusting the threshold of each H, S and L colour. The next step is face tracking using particle filter. It initialised by generating the particle filter randomly around the detected face. The weight of each particle was calculated based on a distance of each particle to face position and resampled to obtain a new particles distribution. The particle with high weight would be selected many times, and particle with small weight would be disappeared. The last process in particle filter is resampling process which was done by averaging the particle's position. The experimental results showed the average error of face tracking using 100, 200 and 500 particles on X and Y axis were (1.25; 1.02), (0.86; 0.81) and (0.59; 0.57) respectively. ]]>

<![CDATA[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. ]]>

<![CDATA[Standard headlights will shine with a fixed intensity even though the environmental light changes. High-intensity lights sometimes make other drivers glare and potentially cause accidents. Adaptive Light Control (ALC) is a car headlights control system that can automatically adjust the intensity of the lamp according to the intensity of the light environment. In this research, we developed ALC which was able to regulate the intensity of the lamp according to the intensity of the environmental light including the light of the car in front. Light settings are performed using a fuzzy control system by utilising environmental light intensity and the distance of the car to the object as input. The developed ALC system was tested on remote control cars equipped with sensors and microcontrollers. The intensity of headlight begins to fade on the distance of the car to the object of 92 cm for objects in front of, 108 cm for objects on the left, and 22 cm for objects on the right.]]>

<![CDATA[This paper presents an online monitoring system and PV system performance analysis under various weather conditions. The PV monitoring system consists of an Arduino sensors circuit, and a design monitor display built using Visual Basic.Net programming. The monitoring system was applied to the 1.25 kW PV system mounted on the roof of the Department of Electrical Engineering, Andalas University. The rooftop PV system is connected to the PLN grid using five units of 250 Wp polycrystalline solar panels and mounted flat in series connected to the load through a 2 kW grid tie inverter. The process of data retrieval of the results of the monitoring took place in real time and displayed in the form of data tables and graphs. The data information of the PV system comes from the sensors connected to the Arduino device which then connected to a PC. Furthermore, data recorded using Visual Basic.Net software converted into Microsoft Excel so it can be analysed further. The PV system performance analysis consists of the synchronisation process, power curve and electrical energy that can be generated by a rooftop PV system. The average solar panels start generating electricity from 7:00 am to 6:00 pm for sunny weather, but for rainy weather, the power of the PV goes down and disconnects early before sunset. The results presented show that the performance of PV systems connected to the PLN network is highly dependent on weather conditions. The monitoring result of power and energy potency can be used as a consideration parameter for a feasibility study of rooftop PV system installed in the tropical area. ]]>

<![CDATA[A Bluetooth was developed as a means for short-range communications. However, the limited range of Bluetooth devices that tend to be narrowly led to the use of Bluetooth is less developed. Whereas, with its properties, sharing of data should be done easily and cheaply. This research has designed a transceiver antenna for Bluetooth communications that works at a frequency 2.4 GHz ISM-band. The antenna is designed in the form of a microstrip antenna with Complementary Split Ring Resonator (CSRR) methods to reduce the dimensions of the antenna. The result of this research is a form of a transceiver antenna that works at a frequency of 2.398 GHz to 2.47 GHz with -30.815 dB return loss and VSWR worth 1,074. The resulting radiation pattern is a directional pattern with a gain of 11.84 dB. Implementation of the CSRR method can reduce antenna dimension by 53.47 %.]]>

<![CDATA[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. ]]>

<![CDATA[The prototype of the electronic system aided personal computer for monitoring the condition of the electric power supply have been done. 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 personal computer 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.]]>
