ANALISIS KONSENTRASI CAMPURAN SENYAWA MENGGUNAKAN VB 2008 ABSTRAK Telah dibuat sebuah program aplikasi menggunakan VB 2008 yang ditujukan untuk menganalisis suatu larutan yang berisi campuran senyawa etil-benzena, o-silena, m-silena, dan p-silena. Konsentrasi dari masing-masing senyawa ini ditentukan menggunakan metode eliminasi Gauss dalam bentuk program komputer yang ditulis menggunakan bahasa pemrograman Visual Basic 2008. Penggunaan program ini terhadap suatu data sekunder, memberikan hasil konsentrasi (dalam satuan molar) sebagai berikut: etil-benzena = 0,04153, o-silena = 0,04067, m-silena = 0,02772,  dan p-silena = 0,02522. Kata kunci: Metode Gauss, VB 2008   ANALYSIS OF MIXED CPMPOUND CONCENTRATION USING VB 2008 ABSTRACT A VB 2008-based  application program  to analyze  a solution containing four different compounds, which are ethyl-benzene, o-xylene, m-xylene, and p-xylene, has been built. Concentration of each compound was then determined by using Gauss elimination method in the form of computer program written in Visual Basic 2008 programming language. Application of the program using the secondary data shows that concentrations (in molar) of each compuound are as follows: ethyl-benzene = 0,04153, o-xylena = 0,04067, m- xylena = 0,02772,  and p- xylena = 0,02522.

OPTIMASI EFISIENSI KOLOM  DALAM KROMATOGRAFI MENGGUNAKAN VISUAL BASIC 2008 ABSTRAK Telah dibuat sebuah program aplikasi yang ditujukan untuk optimasi efisiensi kolom yang digunakan dalam pemisahan secara kromatografi. Parameter-parameter untuk optimasi ini dianalisis menggunakan metode eliminasi Gauss dalam bentuk program komputer yang ditulis menggunakan bahasa pemrograman Visual Basic 2008 Express Edition. Penggunaan program ini terhadap suatu data sekunder memberikan hasil efisiensi kolom optimum, yang dinyatakan sebagai tinggi plat teoritis (H) terkecil, sebesar 0,0223 cm yang dicapai pada laju alir optimum 20,6 cm/det. Kata kunci: Efisiensi kolom, eliminasi Gauss, persamaan van Deemter, Visual Basic 2008   OPTIMIZATION OF COLUMN EFFICIENY IN CHROMATOGRAPHY USING VISUAL BASIC 2008 ABSTRACT An application program to optimize  column efficiency in chromatographic separation had been developed. Optimization parameters were analyzed using Gauss elimination method which was written in the form of a computer program using Visual Basic 2008 Express Edition programming language. Application of the program on the secondary data gave the optimum column efficiency, which was represented as height equivalent to a theoritical plate (H), of 0,0223 cm which was achieved at optimum flow rate of 20,6 cm/det Keywords: Column efficiency, Gauss elimination, van Deemter equation, Visual Basic 2008

Unit Hydrographs

This paper present about design of  Unit hydrographs (UH) application program using three methods of Synthetic Unit Hydrograph namely Gama 1, ITB 1, and Nakayasu. Unit hydrographs are either determined from gauged data or derived using empirically-based synthetic unit hydrograph procedures. In Indonesia, the discharge records may not be available either for several locations or for long time scales, and therefore synthetic unit hydrographs are crucial in flood and water re-sources management. Computer programs were developed to provide a means for rapid analysis. of rainfall and run off data. The purpose of this research is to design computer application program analysis based on three methods of Synthetic Unit Hydrograph namely Gama 1, ITB 1, and Nakayasu. This computer application program use Visual Basic 6.0 as the programming language. This research began from literature studies, lay out design of the display program, the developed of the algorithm, and then carried out using the programming language Visual Basic program, then perform verification and validation program using secondary data. The accomplished results show that computer application program namely Synthetic Unit Hydrograph Program can be used to analyze unit hydrograph which show in table and graph.

Gauss Elimination Method

The Central Processing Unit (CPU) parallel algorithm based on Computing Unified Device Architecture (CUDA) has shown great power of computing speedup ability. What performance will the new technique show in the field of structural computation? We choose the Gauss elimination method as the research object. In this study, the parallel Gauss elimination is realized in CUDA on GPU. Furthermore, we carry out two groups of numerical experiments. The first group investigates the effect of Matrix Bandwidths (MBs) and Node Numbers (NNs) on speedup ratio. The second one compares our method with the commercial software by analyzing two actual structural problems in ocean engineering.
