Abstract

Interdiffusion mechanism of catechin, catechutannic acid and quercetin are studied by using DFT-B method. But before conducting these experiment, we perform molecular dynamic simulations to find adsorption models probability of each compound. Two models adsorption of quarcetin, four models for catechin and three models for catechutannic acid have been obtained from molecular dynamic simulations. Quantum parameter of each compound, energy and properties adsorption models have been calculated and discussed. The theoretical results were found to be consistent with the experimental data reported. Futhermore, optimization adsorption model samples show that all of adsorbents have weak bonds on the surface of silver nanoparticles. The mechanism can be classified as strong physisorption, so that catechin, catechutannic acid and quercetin can be categorized as good capping agent in synthesis of silver nanoparticles.

Abstract

ABSTRAKTelah dilakukan atenuasi multiple berbasis Seismic Unix pada data seismik 2D laut dalam (3000- 5000 meter) pada cekungan Bryant Canyon lepas pantai teluk Louisiana Texas. Atenuasi dilakukan pada empat line seismik dengan metode Predictive Deconvolution, Transformasi Radon, dan kombinasi Predictive Deconvolution dengan Transformasi Radon atau disebut TauP Deconvolution. Penelitian ini ditujukan untuk mengetahui efektifitas ketiga metode dalam mengatenuasi multiple pada data seismik laut dalam dengan struktur geologi kompleks. Pada keempat line seismik tersebut teridentifikasi water-bottom, peg-leg, dan intrabed multiple. Metode Predictive dan TauP Deconvolution efektif digunakan untuk menghilangkan peg-leg, intrabed multiple, dan multiple di sekitar kubah garam (pada line 3) namun tidak dapat mengatenuasi water-bottom multiple. Kedua metode juga berhasil meningkatkan signal to noise ratio serta memperbaiki dead trace. Metode Transformasi Radon terbukti tidak efektif untuk mengatenuasi multiple laut dalam dengan morfologi yang kompleks.Kata Kunci :   Multiple, Predictive Deconvolution, Transformasi Radon, TauP Deconvolution.AbstractSeismic Unix based - multiple attenuation has been performed on 2D seismic data on deep ocean (3000-5000 metres) of Bryant Canyon basins offshore Louisiana Gulf Texas. Attenuation was performed on four seismic lines by Predictive Deconvolution, Radon Transform, and the combination of Predictive Deconvolution and Radon Transform or called the TauP Deconvolution methods. This study aimed to find out the effectiveness of the three methods in multiple attenuation on marine seismic data in structure geological complex. Water-bottom, peg-leg, and intrabed multiples were identified in the four seismic lines. Predictive Deconvolution method and TauP Deconvolution methods are effective for removing peg-leg, intrabed and salt-related multiples (identified on seismic line 3) but the two methods fail to attenuate water-bottom multiples. The two methods have also successfully enhanced signal to noise ratio and fixed the dead traces. Radon transform method was prooped to be in effective for deep water and complex structure multiple elimination. Keywords :  Multiple, Predictive Deconvolution, Radon Transform, TauP Deconvolution.

Unfortunately, until now, Karang Rejo Village at Jorong District of Tanah Laut Regency doesn’t have yet criteria with levels of prominence to make that decision. By that means, it’s necessary to make a decision support system that could support as alternative decision in defining the poverty level of each family in the Village. In the calculation on defining family poverty for the system uses MADM Yager Fuzzy Method. As for the system development uses the waterfall method. The result of this decision support system is a family data with classifications and levels of poverty. With the result that conclusion of this system is there’s a 40% difference between the system decision and the village representative’s.
