<![CDATA[In the industry era, especially the oil processing industry, the heat exchanger is needed to regulate temperature and produce oil products such as petroleum, kerosene and diesel fuel. In the operation, the heat exchanger requires maintenance, especially when the minor unit is shut down or stop and routine reparation. Maintenance is done by replacing the tubesheet that commonly referred to as bundle retube where there are pipe fritter to be cleaned, which are cutted at the time of maintenance. This maintenance is typically done in manual approach, which is not efficient in terms of time. For a more efficient maintanence, this paper proposes a prototype design to discard these pipes fritter by utilizing image processing method for detecting the edge of the circle and the position of the pipe fritter. Based on the experiments, it has been obtained that the test circle radius that can be captured is at 4 to 10 pixels. The longest time for positioning was 2.41 minutes and the whole process of disposal of this pipeline reaches 47.92 %.]]>

<![CDATA[Information system and data is a very important thing nowadays. An information system especially a database is designed with a high data availability. One of the database systems is MySQL cluster. Sometimes, its performance decreased because of the system’s incapablity to handle the data. To overcome this problem, the research of load balancing systems for MySQL cluster is needed. This research is intended to analyze the effect of load balancing clustering methods on MySQL cluster which by default has been set as failover clustering. The analysis is done through data collection and database transactions test to get the number of Transactions per second (TPS) and response time parameter using SysBench. The test is divided into two main scenarios, the simple and complex-mode that running on 4 computers. The tests were conducted by giving workloads from 8 up to 128 threads respectively to the server through a client on default conditions and load balancing. The test results showed the number of TPS at MySQL cluster default is 536.61. In contrast, number of TPS at load balancing is better at 2261.22. Likewise, the response time at MySQL cluster load balancing is 147.55 ms faster than that of the default one at 335.00 ms.]]>

<![CDATA[Monitoring the output parameters of a solar module is required for assessing its performance under real operating conditions. This paper presents a new technique for monitoring the output parameters i.e. current and voltage of solar module directly under real operating conditions. In this new monitoring technique, the output parameters of a solar module can be directly processed in real time condition and their results are displayed in a graph. The monitoring system is developed using microprocessor Arduino Atmega 328P and equipped with calibrated current and voltage sensors, a data acquisition system which is integrated directly into an Excel spreadsheet using the PLX-DAQ application program and a memory card for backup. The monitoring system is connected to a computer using a RS232 serial port. The collected data is saved directly into a spreadsheet and plotted in real time. This technique provides an easy access to the collected data for further analysis.]]>

<![CDATA[Fingerprint image matching is an important procedure in fingerprint recognition. Robust fingerprint image matching under a variety of different image capture conditions is difficult to achieve, because of changes in finger pressure, variation of the angle, etc. Fingerprint matching is very important for the development of fingerprint system recognition that is sensitive to finger pressure. This paper proposes a fingerprint matching algorithm that enables the so-called fingerprint template (extracted specific part (region of interest (ROI)) of a person’s fingerprints to be matched to the different fingerprint of the same person or different people taken on different time, angle and a different finger pressure using normalized cross-correlation (NCC). This algorithm was implemented in MATLAB. The results showed that the maximum NCC value for ROI of the source fingerprints and targets that was greater than 0.62 indicates a strong correlation or similarity. ]]>

<![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.]]>
