<![CDATA[In this research, proposed lighting in smartroom with PoE technology (Power over Ethernet). IT facility is PoE Switch, Ethernet Cable and LAN network. Smartroom in this study is defined as meeting room in a high rise building that has LAN network. This research is motivated by many lighting lamps that use AC power, when the future use of AC source will be reduced, even with PoE switch voltage source still use AC, but can eliminate the pitch of light that still uses conventional AC. Building infrastructure systems tend to be developed towards IP protocols. An area where the electrical area becomes fully integrated into the IP network. This is made possible through the use of LED with low voltage and low current. However, in order to utilize the technical and economic advantages offered by LED Lighting Solutions, the addition of light sensor and motion as a switch will make it more complete. The results of the study obtained a cheaper cost than the use without PoE.]]>

<![CDATA[Direct Digital Synthesizer (DDS) applies a method to generate an analog waveform in a digital manner, which is formed by generating a digital signal that varies with time and converting it into analog form using a digital to analog device (DAC). IC AD9851 is an analog waveform generator to implement the DDS method, which generates a frequency that can be changed according to the needs of its users. The digital signal is generated using a PIC 18F4550 microcontroller that has a full-speed USB 2.0 feature to interface with the computer via USB without the need of special drivers to do the communication. Setting of the output frequency can be done via the keypad or buttons programmed via computer. The test results are a wide range of frequency waves produced from 100 Hz to 30 MHz in the form of a sine wave with an amplitude of 430 mV and a square wave with an amplitude of 4,125 V.Keywords: DDS, AD9851, PIC 18F4550, USB, function generator]]>

<![CDATA[Kota Baru Parahyangan residential area, located in Padalarang sub-district of Bandung, has the quality and coverage of 3G and 4G cellular services that are not optimal, thus it has become a complaint of customers to the cellular providers. Therefore in this article a camouflage tower or Outdoor Distributed Antenna System (ODAS) is designed, which is a unique concept that helps in prividing connectivity in location where conventional tower construction is not permitted due to various regulations. This camouflage tower design aims to increase the number of cellular antennas but with minimal costs, land and human resources. In addition, this camouflage tower design has a high aesthetic value to be implemented in these elite residential areas. From the design and implementation results for 4G, the Reference Signal Received Power (RSRP) value is 70% at a value -90 dBm and Signal-to-Interference Noise Ratio (SINR) 70% at a value 5 dB according to the Key Performance Indicator (KPI) provider standard, while for 3G the Received Signal Code Power (RSCP) value is 70% at a value -78 dBm and Ec / No -12 dB. This shows that the quality and coverage both of 3G and 4G cellular services in this region have reached the target cellular providers.]]>

<![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[Computer or Personal Computer (PC) based data acquisition system had enabled the measurement of physical parameters, not only to display and store them in the computer but also to send them to a website. Twitter as one of web services for social media that provides the facility to display 140-character length of text status has been deemed sufficient for the purpose of displaying the latest data and is accessible through available Application Programming Interface (API). The purpose of this research is to design a PC-based data acquisition system which is capable to conduct measurement, storage and transmission of data to the web service via Twitter API. The proposed system was consisted of LM35 temperature sensor to measure room temperature, Arduino Nano microcontroller and a data acquisition application in PC to display and store data in a Comma-Separated Values (CSV) file. Based on test results for processes involving Analog to Digital Converter (ADC), the obtained error is 3.71% for voltage value and the average difference between measured values and displayed ones is 0.01 V. Average error for temperature measurement is 5.13% and the difference between measured values and the displayed ones is 1.34°C. Built application had produced an adequate display of interface and fulfilled all required functionalities. Average response time of Twitter API to Choreo is 0.18 s while average time to transmit data from application to Twitter is 2.15 s or 11.75 times longer. In later development, LM35 should be replaced with a more precise sensor. The occurrence of randomness in measurement results could be minimized by adding an active filter circuit between sensor and microcontroller.]]>

<![CDATA[The installation of a Solar Power System (PLTS) within the ideal conditions still uses the type of solar module with the same current and voltage characteristics. However, these ideal conditions can be different if the commonly used modules are no longer available on the market. Once there is damage or interference in the operating system, such as cracks in the module plate, it will take a significantly long time to replace. This particular condition can obstruct electrical power distribution to its intended loads in the other end. Therefore, creating a robust solar panel system that operates at its maximum capacity requires an alternative or approach to find such a similar module replacement. It is expected that the replacement module will have the I-V characteristics, which relatively resemble that of the earlier module and can help to maintain the energy availability of the solar panel system. This study aims to analyze which factors affect the characteristic irregularity of currents and voltages in a solar panel installation towards the output of a solar panel under certain conditions. The solar panel system is designed using 20 solar modules with each capacity is 250 WP power that is simulated with Simulink. The method creates the mismatch condition of the current and voltage on the solar module in a specific panel configuration. These mismatch conditions are created by combining solar modules with different currents and voltages in the Series (S) and Series-Parallel (SP) configurations. The simulation is carried out by replacing the main solar module with a 5% to 100% replacement solar module. The selection of the replacement module is based on Isc, which is close to the same because the current flowing in the series circuit is the same. The simulation results showed that the solar panel system still functioned properly and produced maximum power under mismatch conditions. Of all three configurations with mismatch conditions, it is found that the best performing configuration works with the Series-Parallel (SP) configuration of the STC conditions. The maximum power which can be sustained with Series-Parallel (SP) configuration reaches up to 40% of the original modules.]]>

<![CDATA[Paralysis is a disease that can limit the mobility of the sufferer. One solution that can help people with paralysis in carrying out their mobility is the use of an electric wheelchair. In this study, an electric wheelchair with specifications where the wheelchair motion control uses muscles on both arms, so that the electric wheelchair is very suitable for patients with paralysis in the legs and weak hand strength in turning the wheels from the wheelchair. The input of motion control commands is carried out through an electromyograph sensor mounted on the flexor muscle in both patients’ arms. The output of each sensor is given a threshold of 2 volts to distinguish control commands or not. When the sensor output is more than the same as the threshold, it is considered logic one and the other is considered logic zero. The method is used to interpret the output as a control command by impulse detection. The electric wheelchair movement that can be done is forward, turn right, and turn left.]]>

<![CDATA[The uncrewed Aerial Vehicle (UAV) operation is currently dominated by autonomous technology (autopilot) rather than manual control via remote control. During flying the mission autonomously, communication between the UAV and the Ground Control Station (GCS) must be in good and stable conditions. The GCS can well receive the telemetry data and payload sensor data carried by the vehicle. Conversely, any inconsistency parameters can be corrected by the GCS before transmitted to the UAV. Therefore, the role of the antenna is crucial to avoid signal loss during the communication process. This study focuses on GCS’s antenna. By designing the Yagi type antenna with the optimization of the distance, the number of directors, material, and shape of the reflector through CST simulation. The best option chosen is the Yagi antenna with the same distance between directors, seven directors, copper material, and flat reflectors with a VSWR of 1.1134, return loss -25.411 dB and 10.7 dB of gain. The measurement result after fabrication is the VSWR of 2.165 and the return loss of -8.677 dB. The antenna test results, when the UAV was flown as far as 2.5 km, found that the signal strength received by the GCS is -70.68 dBm with RSSI 107, and the signal strength in percent is 96%. ]]>
