<![CDATA[Grid computing is a group of computers that connected to computer network and working together to complete a certain task. The computers inside must be coheren so the processors can work evenly when given a task from server. Grid computing can be used in many areas and purpopes, and in this research it will be used to compile C/C++ program. Compilation is a process to transform a human readable source code into a computer readable code. The compilation process will take place in a personal computer (PC). By using grid system in compilation process, the waiting time of a source code will be reduced as the compilation task will be divided among the computers. For that reason a C/C++ compiler software that using grid computing will be made. The task will be distributed among the computers inside the grid. It can also help someone who want to compile C/C++ source code but he doesn’t have the compiler on his PC. ]]>

<![CDATA[This research is aimed to know the effect of mixing time, mixing speed and curing temperature on morphological and mechanical properties of epoxy-albasia wood fiber composites. The method used in the manufacturing process was hand lay-up method. The fibers with 30 mesh and 25% volume fraction are mixed with epoxy for the time variations of 15 and 45 minutes by speed variation of 695 rpm, 773 rpm, and 853 rpm. In order to investigate the effects of curing temperature, the same mixture was blended manually for 20 minutes and cured with the temperature variation of 40, 50, 60, 70 and 800C. Experimental results show that mixing the fiber and matrix with the speed of 695 rpm for 15 minutes increases the tensile strength but slightly declines the impact strength. This phenomenon could be possibly caused by the longer the mixing time, the higher the amount of foreign particles entered into the mixture that could affect its properties. Both the tensile and impact tests show that the temperature of 80oC is the optimum curing temperature for epoxy-albasia wood fiber composites. Crack deflection presented by Scanning Electron Microscopy (SEM) micrographs results in an increase in the crack propagation path and in the energy-dissipating events in the region immediately ahead of the crack tip.]]>

<![CDATA[The Indonesian Red Cross (PMI) is a national national association organization in Indonesia engaged in the field of social, humanitarian and health. The logistics section of the Blood Transfusion Unit (UTD) is a warehouse where blood stock is store in, out, or destroyed blood. The importance of blood availability at requires The Indonesian Red Cross requires The Indonesian Red Cross to always maintain the availaibility of blood to meet the need for blood tranfusion . the application of prediction as an effort to control blood supply is considered important. This is needed to minimize the amount of ordering and storing blood that must be borne by The Indonesian Red Cross. For this reson, a precise prediction method is needed in order to produce an accurate estimate of blood supply. In this study the prediction of blood is done using the Weigthed Moving Average (WMA) method, because the patern of stock data and blood demand owned by The Indonesian Red Cross follows the trend data pattern. Comparison of the smallest error value between the 3th-month WMA period and 6th-month WMA selected to be the result of focasting. The results of the average error value (MAD, MSE, and MAPE) show a period of 6 months has the smallest value, although there is a decline in blood type AB, but the difference in the ratio of error values in goldar AB is not too far. This happens because donors or requests for AB goldar are not too many.]]>

<![CDATA[Postweld heat treatment (PWHT) is a common practice among building codes to reduce the residual stress, improve the ductility, and decrease the defects. This article describes the welding joint property of motorcycle crankcase material by taking tungsten inert gas (TIG) welding measures before PWHT on 200°C with holding time of 0,4,6, 8 hours. Test data were analyzed in relation to tensile strength, hardness and microstructure on the welding joint. The regions corresponding to the base metal (BM) and heat-affected zone (HAZ) were studied. The effect of holding time under PWHT on properties of joints can be investigated. The results demonstrated that micro-hardness in the weld and tensile strength decreased with PWHT time prolonging, while tensile strength increased with the extension of PWHT time. The microstructure before PWHT was coarse in the joint. With the extension of holding time under PWHT, the structure obtains fine grain and the characteristic becomes obvious.]]>
