Abstract

Geometric Improvement Of Trace Network Road with Remote Sensing and Geographic Information System. Together with a great development in road network at such district, it must be followed by changing information that should be suited to the condition at present. For supporting the information changes, the remote sensing technology could be applied. It is one of technology with a great increment and needed to various applications. The application of remote sensing technology is close related to spatial field which is used to be achieved from non digital because of limitation facilities and other obstacle. However with remote sensing technology, those can not be burdened anymore and the information achieved can be updated. The presence of remote sensing technology is followed by emerging of Geographic Information System technology which promises a new era in providing deep information and spatial object analysis. The object identification through Landsat Thematic Mapper (LTM) image with (30x30) meter spatial and 7 (seven) band spectral resolution. The composite image together with image contrast improvement are applied to supervised classification covered object for obtaining classified and corrected image that can be used to analyze network road improvement and create database information of trace network road using Geographic Information system.

Abstract

Spatial dispersed pattern of Industry at Jalan Raya Bogor Corridor. The corridor Jalan Raya Bogor, includes DKI Jakarta and West Java provinces have 186 industry, which different spatial dispersed pattern. The Industry has an impact to local community for worker industry. The analysis with nearness neighborhood and overlay map are conclusion as industry has cluster pattern at Cisalak Pasar, Cilangkap, and Cisalak district. And the industry patterns have random spatial at Tugu, Mekarsari, Sukamaju Baru, and Jatijajar district. The industry spatial has a dispersed pattern/uniform at Susukan, Ciracas, Pekayon, Curug, and Sukamaju district. The local community for worker industry has 62.04% senior high school and 2.81% elementary school or not education

Abstract

Infrared Spectroscopy of Precipitated Calcium Phosphate Compound. Samples of calcium phosphate compounds were produced from saturated solutions containing of calcium and phosphate ions. The experiments were carried out using solutions at temperature 25 º C and 70 º C, combined with different pH value of 5, 7, 9 and 11. Precipitation mass from solutions at 70 º C was relatively higher compare to that produced from solutions at 25 º C. It was also shown that generally the mass precipitation rose with the increasing of pH. Sample analyses were performed with the use of infrared spectroscopy, particularly for the samples produced from solutions at 70 º C. Based on the ν4 phosphate absorption band, it was indicated that apatite crystals found in most samples which its amount gave rise to the increasing of pH. Infrared spectroscopy of the heated samples produced with pH 11 showed that water molecules could be present either at the surface of crystals or trapped in the crystal structure.

Abstract

Influence of output window reflections on oscillatory processes in gyrotrons has been studied. The processes in a gyrotron have been modeled numerically, and enhancement of the spectrum signal in the presence of reflections has been studied. Dependencies of output power versus time and frequency spectrum for different value of reflection coefficient are given. Possibilities of significant increasing of output spectrum are demonstrated experimentally. The results demonstrate significant influence of reflections on operation stability and composition of the output radiation of the gyrotron.

Abstract

In an attempt to synthesize [BzMe3N]2Mo2O5(OMe)5 from the reaction of [BzMe3N]2MoO4 and MoO(OMe)4 in the ratio of 1:1 in methanol has produced [BzMe3N]2Mo4O10(OMe)6. The formation of [Mo4O10(OMe)6]2- anion suggests that ligand dissociation has occured in solution. Suitable crystals for X-ray chrystallographic were obtained from hot methanol and the crystal structure of [BzMe3N]2Mo4O10(OMe)6 has been solved and reported here in.

Abstract

The investigation for antifungal effect of medicinal plants, combination infusion of Piper bettle leaves, Punica granatum Fructus Cortec, Curcuma domestica Rhizome. The tested demartophyta used Candida albicans. This research using dilution method to determine of minimum inhibitory concentration (MIC) and difusion method to determine zone inhibition around of disc. The results of determination of MIC showed that combination infusion Piper bettle leaves with Punica granatum Fructus Cortex against C. albicans respectively, 31,2 mg/ml : 7,8 mg/ml; 15,6 mg/ml : 15,6 mg/ml and 7,8 mg/ml : 31,2 mg/ml. The determination for zone inhibition from 3 concentration of infusion of Piper bettle leaves with 3 concentration of Punica granatum Fructus Cortex with 9 combination against C. albicans showed that combination of two infusion is the larger than the single infusion.
