<![CDATA[An accurate calculation of feed nutrition and more affordable price is an extremely complex. Firefly algorithm is an algorithm designed for optimization calculation whose output is highly dependent on light intensity (β), which is influenced by distance (r). Therefore, in order to produce maximum output values, an optimization of firefly distance should be done. The most appropriate method is Newton’s Method as it has the capability of solving roots of equations accurately. From the testing of distance optimization in firefly algorithm, a fairly good increase in the fitness value was obtained.Keywords: Newton Method, Firefly Algorithm]]>

<![CDATA[The processor development today is on multi-core and multi-processor which can be used to a speedup of data processing time compared with one processor core only. One of the main ways that can be used to speed up the data processing time is by using multi-thread. Multi-thread method has been implemented on the robot telemonitoring system based a Graphical User Interface (GUI) which has been developed in Research Center for Electrical Power and Mechatronics, Indonesian Institute of Sciences (LIPI). A part that requires high processing time at the telemonitoring systems are the display of real-time thermal cameras and color camera along with tracking algorithm used, it can be seen from the thermal camera display which less smooth. Two threads have been added to process each of the cameras separately. C programming language, with the opencv library and the Integrated Development Environment (IDE) Qt Creator has been used to implement this method into an application program. Based on experiments, it can be seen that both of the camera display with tracking algorithm used can run more quickly, it is demonstrated with the smooth display and the processing time is faster than a sequential program. The processing time based cpu time in sequential program both on color camera and thermal camera is 6 fps, while in multi-thread program (with added two threads), the processing time is 6 fps for color cameras and thermal camera is become 7 fps. The processing time based wall clock time in the sequential program on color camera and thermal camera is 6.31579 fps, while in multi-thread program (with added two threads), the processing time is 6.31579 fps for color cameras and thermal camera becomes 7.5 fps. The speedup and efficiency obtained between the sequential program and with added two threads are 0.84211 and 0.28070. Keywords: multi-thread, telemonitoring, GUI, Qt creator, c language]]>

<![CDATA[Voyage Account is an application that record consumption data on each voyage, then the data is used to calculate the profit or loss of each voyage. The application interface was created using Windows Presentation Foundation (WPF). Prototyping development methods were used to create these applications, C# as the programming language, and SQL Server 2012 as the database. This study discusses the making of the interface, backend, and database of application. WPF has been selected, because WPF is the latest technology developed by Microsoft after WinForms. WPF presents a display that can be customized to user needs. The test results showed that the Voyage Account application is already functioning in accordance with wishes of the user, the test is done using sql query by entering the appropriate username and password and match the query returns results with what is displayed by the application. As for testing the interface shows if WPF can be flexibly adapted to the screen resolution of 1366 x 768, 1920 x 1080 and 1280 x 720.Keyword:Â Voyage Account, WPF, prototyping, C#, SQL Server 2012.]]>

<![CDATA[Control position and reduction of swinging of the payload of a rigid gantry crane system is a challenging work because of under-actuated system. This paper addresses challenges by proposing the artificial bee colony (ABC) algorithm to optimize the gains of the PD controller to form what the so-called the artificial bee colony (ABC)-PD controller. The effectiveness of the proposed control algorithm is tested under constant step functions and compared with Ziegler-Nichols (ZN)-PD controller. The results show that the proposed controller produces slower rise time and peak time, but faster settling time than the ZN-PD controller as well as no overshoot under the predefined trajectories.  ]]>

<![CDATA[Preprocessing is a process to avail a clean and ready data for data mining analysis. Four stages are carried out in this process i.e. data selecting, data cleaning, data integrating and data transforming. The numerous semi structured pattern of web server log data accumulation has made the data cleaning-up to select the really needed data difficult. Hence, in this research a technique to carry out data cleaning using parser algorithm and query processing is proposed. The parser algorithm is written using PHP programming as web based programming, while the query processing is implemented using relationship database management system (RDBMS) MySQL. The computation system is tested using twenty six different sized trial data, originated from six web server. The final result concluded that in general the data being tested have 80 percent decreasing average with average processing velocity of 9.28 mbpsKeywords: query processing, parser algorithm, semi structured data, web log data]]>
