<![CDATA[SVM is one of machine leaning is used for pattern recognition classification. In this research, linear SVM methods will be applied to analyze multivariable classification. As an input signal the PQRST signal is used from the measurement results of the ECG cardiac activity device. ECG signals in this study were processed using HRV methods in the time domain. Classification is used to compare ECG signals from measurement result in sitting and standing activities. As a tool designed a heart rate monitoring tool (ECG) with a processor using the Arduino UNO module and the AD8232 ECG amplifier module . The results of ECG signal extraction by the HRV method obtained 11 ECG features (variables). In the traning data contain 10 data and one other file containing 4 ECG data for testing data. In the data transfer process there are 110 features of traning data and 44 features in testing data. The results of the traning data have 100 % accuracy, so that it will procedure a hyperplane that is able to separate the two classes sitting and standing. From the results of testing with the hyperplane the system can classify properly.]]>

<![CDATA[In this research, the design and fabrication of microstrip antennas with circular polarization was is done to overcome the deviation of the antenna polarization angles, using microstrip line fed with a coaxial probe for Microwave Radio applications that work on the 11 GHz frequency band. To be able to produce circular or circular polarization on each patch of antenna arranged in an array, then it is done bit by bit (iteration) with the truncated corner technique on the edges and angles of the rectangular patch to produce an Axial Ratio of dec 3 deciBell.The type of substrate used in this study is FR4 with a relative dielectric constant value (Ɛr) = 4.58 and thickness (h) = 1.6 mm. By adjusting the cutting angle on the side of the patch, a circular polarization is generated with an Axial Ratio of a software simulation result of 1.065 dB and a bandwidth of 900 MHz at a frequency of 11 GHz. The final result of antenna fabrication tested at the Indonesian Institute of Sciences (LIPI) Electronics and Telecommunications laboratory in Bandung on May 29, 2019 consisted of a return loss value of -20,14 dB and VSWR 1.22 on the 11000 MHz frequency. The radiation pattern measurement results in a Half Power Beam Width value of 20 ° and an antenna gain of 7.02 dBi.]]>

<![CDATA[This study aims to develop an attractive multiplatform learning robot and supported by a programming system that is easily understood by adolescents. Learning robots developed are wheeled educational robots that can be controlled manually using a controller (manual transporter) and automatically using sensors (line follower and automatic avoider). As data processing on the robot, two Arduino Nano are used with the help of Arduino IDE software, and for sending data, serial communication between Arduino Nano is used. The sensors used in this robot are light based sensors for line follower and ultrasonic for automatic avoiders. In addition, there is a separate controller from the robot in the form of the MIT APP Inventor program installed on a smartphone device and connected to the Bluetooth module on the robot for manual transporter. From the test results, the robot runs accurately following the black or white lines and successfully moves items, for automatic avoiders the robot can detect walls and follow the grooves of the wall with an angle of 90 degrees, while for manual transporter robots can be controlled using a controller application on an Android-based smartphone developed with MIT APP Inventor.]]>

<![CDATA[Along with the development of the technology even more advanced and requires humans to create the latest technology to simplify and accelerate work and just a lifestyle to indulge themselves in undergoing their daily activities. Cordless power transfer is a system of power transfer without using cables that are directly connected between voltage sources and electronic devices that are expected to simplify and improve the quality of human lives. This study aims to design a wireless power transfer. In this case the method or principle of electromagnetic inductive resonance is used among several other methods including radio waves and laser light. The main results to be achieved are providing information that it turns out that energy can be channeled without using cable media directly. This wireless energy transfer proves that the energy from electromagnetic waves around us can be harvested again into alternative energy sources and this is very promising.]]>

<![CDATA[Detection of emotions from text is a problem of text classification based on the type of emotion. The availability of an emotional corpus plays an essential role in the detection of emotions. However, most corpus for emotional detection is available in English. This condition is a major problem when developing a system for detecting emotions from Indonesian texts. The emotional text corpus for Indonesian is very limited. Therefore, this research focuses on the development of Indonesian text emotional corpus. The development of such a corpus is the first step in the study of detecting emotions from the Indonesian text. The data source used to develop the corpus is a tweet. The annotation process is done automatically based on the hashtag (#) of emotions contained in a tweet with five types of emotions: happy, sad, angry, afraid, and love. This research produced an Indonesian emotional text corpus consisting of 500 complete tweets with emotional labels at the superordinate and basic levels. Emotion detection experiments were conducted to test the corpus using the Naive Bayes method. The accuracy of the experiments reached 82%, these results indicate that the corpus can be used in text emotion detection.]]>

<![CDATA[Geographic Information System (GIS) is an application that has many benefits and implementation, One of the GIS implementation is area mapping. implementation GIS for web based monitoring Fiber Optic networking system integrated with client in mobile application will be analyzed in this Thesis. The ability to send data and image real time also will be applied in this implementation. Parameters to be tested in the data transmission process between the system dashboard and mobile application is latency with a number of combinations of the number of clients. The result of the function test is that there is an increase in latency if the number of clients that access the dashboard system server is more. Latency is affected by signal strength on the client device and the location of data input on the client. The dashboard system is equipped with a Service Level Agreement (SLA) percentage calculation that is affected by the length of downtime or failure of the Fiber Optic network system. SLA calculations on the dashboard system are done automatically and the percentage generated is in accordance with manual mathematical calculations.]]>
