<![CDATA[Internal fixation is a method of healing fractures by connecting them using metal called pen. Pen metal in the body isn’t permanent, when the bone was strong the pen must be removed to avoid infection. In finding the pen, X-Ray are usually used. But X-Ray has bad effect, so not everyone is allowed to use it. The solution given by make prototype to detect pen location using B-Mode ultrasonic scanning method, it uses 5MHz single transducerultrasonic. Objects measurement is the animal bones connected with metals placed in the jelly with different heights. From the two transducers, the concave surface transducer has a better result and smaller percentage error than the flat surface transducer. The concave surface transducer has a focal length area 1.94cm above the transducer surface. The maximum slope angle of the object is 20o, which more than that makes the echo signal unreadable the object.The measurement results of objects displayed in the B-Mode 1 dimensional on PC that displays the structure of the bottom surface of an object, based on comparison between the actual object and the B-Mode display an error less than 6%, meaning B-Mode can represent the surface structure bottom of the actual object.]]>

<![CDATA[A bridge is planned and built with a certain capability against vehicles through it. The vehicles movement causes vibration and vertical deflection on certain parts of the bridge. If the vibration occurs continuously in a great value, then the bridge will be damaged sooner than had been planned. This research reports a design of a vertical deflection measuring system prototype on bridge, employing an accelerometer MMA7361 sensor which is controlledby ATmega32. The system was tested by manually loading the trial bridge with 1 m of length. The loading deflects down the bridge to maximum 15 cm from the reference point. Sensor readout data was sent wirelessly using ZigBee real time to computer in a graphical display for easy analysis. The research give an alternative method in vertical deflection measuring on the bridge that can be utilized by stakeholder in policy decision.]]>

<![CDATA[Until now, Internet of Things (IoT) is a very interesting topic to research. This is due to the wide role that IoT can play in human life. This study aims to compare the performance of two sensors in an IoT-based distance detection system with the focus of the parameters being tested: sensor readings, Qos of data transmission, and power requirements. The two sensors that are the subject of comparison are HC-SR04 and GP2YA21YK. As an analytical tool, this research uses two tools, namely Thingspeak and Wireshak. The performance test results show that in terms of accuracy in determining distance, the HC-SR04 has a much better performance than the GP2YA21YK. On HC SR04, the average reading error is 0.82 cm, while on GP2YA21YK it is 14.40 cm. Meanwhile, in terms of QoS parameters, the two sensor systems show almost commensurate performance, the packet loss is both 0%, the throughput value is 37.01 kbps on HC-SR04 and 38.12 kbps on GP2YA21YK. As for the delay, the HC-SR04 sensor gives a value of 33.55 ms, and on GP2YA21YK it is 26.1 ms. Furthermore, based on power requirements, sensor systems using the HC-SR04 consume 14.36% less power than the system that use GP2YA21YK. By referring to the results of measurements and visualizations using Wireshark and Thingspeak, it can be concluded that the distance detection system using the HC-SR04 sensor is better than the system with the GP2YA21YK.]]>

<![CDATA[Solar panels are an essential part of a system of electrical source devices that receives light energy to be processed into electrical energy with direct current (DC) output. The main problem in the use of solar panels is that the production of power in solar panels is not constant due to the temperature and solar radiation changes. This non-constant power causes the solar panel output power to fluctuate and become unstable. This output power will be used in processing using the MPPT Perturb and Observe (PNO) method to obtain the maximum solar panel receiving point. This PNO method uses two input parameters and can be applied to all types of solar panels. This study aims to reduce the oscillation of the output power of MPPT using electronic power simulations on a three-level boost converter by combining PNO and Fuzzy MPPT methods. The Fuzzy method in this study uses the Mamdani inference method, which uses two inputs and one output. The boost converter was tested using a simulation on several conditions of sunlight received by solar panels. The simulation results show that the power output from the MPPT PNO and Fuzzy methods can reduce oscillation more optimally, 78.57%. ]]>

<![CDATA[This research is motivated by electrical power shutting-down that frequently occurred in Riau province. Low electrical power supply as compared to the need causes lack of supply. Thus, new alternative electrical energy resource such as micro hydro is required. Micro hydro plant is an electrical power generators that uses water to rotate the turbine. This research designs a monitoring system for micro hydro plant. The monitored micro hydro plant employs water turbine that is constructed using bicycle pedal and a water pipe installed on the pedal . The pipe flows the water to energize the turbine. Turbine rotation will generate electricity. The amount of power resulted by generators depends on the number of turbine rotation. The power is used to turn on the lamp. Some sensors are used to monitor generator performance. Current, voltage, and rotation sensors are used to monitor the resulted current, voltage, the turbine rotation respectively. The output power is stored in the battery. The micro Arduino and the ethernet shield capture the monitored data and send it to the computers using Wi-Fi connection. Measurement results show that the output voltage produced by the generator is 10 Volts when the water volume is high. Finally, it is found that the micro hydro generator is able to supply 5 Watts to the load.]]>

<![CDATA[Light or sunlight can be converted into electricity using solar panel technology. The measurement process is needed on current and voltage parameters to determine whether a solar panel is working correctly or not. The application of the Internet of Things (IoT) is a suitable method for monitoring efficiency measurements on solar panel performance in real-time by combining several computational components, protocols, and sensors to interact more quickly and help all activities become more efficient. One IoT technology that can work efficiently is the Long Range Wide Area Network (LoRaWAN). LoRa communicates using radio frequencies with a wide coverage range and has a low power consumption level. In this study, the implementation of LoRaWAN technology as a communication protocol between three series of nodes and one gateway in building a solar panel system is then visualized on a web that can monitor currents and voltages in the form of graphs and numbers. Displays notifications when there is a change in the condition of the large voltage from the solar panel can control the state of turning on or off the lights and turning off the whole node, and displaying a history of current and voltage readings. The functionality of the system will later be tested using black-box testing. There was also a distribution of questionnaires to 35 respondents to measure the level of agreement that the system designed was running well. ]]>

<![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.]]>

<![CDATA[Scholarship is a donation in term of financial assistance that is given to an individual, student or pupils. Even though, the target distribution of the scholarships is sometime not relevant. It is because the scholarship distribution has not yet used a tool or method to determine suitable scholarship recipients. For that reason, it needs to design a system to determine the scholarship recipients using Fuzzy Multi Attribute Decision Making (FMADM) and Simple Additive Weighting (SAW) method. FMADM method is used to looking for an alternative of some Alternatives with some criteria that determined before. Moreover, SAW method is used to rank the existing alternatives. The result of this research can be used as a tool to make decision with recommendation of the scholarship recipients.]]>
