Abstract

Lamda (λ) Mu (μ) Rho (ρ) seismic inversion method has been applied to identify the distribution ofconglomerate reservoir in Melandong Field, Northwest Java Basin. This research used 3D pre-stack timemigration seismic dataset with one well data and a checkshot data. A sensitivity test analysis was done tosee the validity of the dataset and well seismic tie has been applied before generating a background modelfor the inversion processes. The outcomes of this research show that Lamda Rho ( λρ) inversion can be usedto detect the presence of hydrocarbon in a conglomerate rock and it is shown by value ranging between 33-39 (GPA*(Gr/cc)). Besides that, Mu Rho (μρ) inversion can indicate the rock type and it shows thatconglomerate has higher value (26 – 32 (GPA*(Gr/cc)) than claystone (20-26 (GPA*(Gr/cc)). By combiningboth Lamda-Rho and Mu-Rho inversion results, the distribution of the reservoir rock and hydrocarbon caneasily be detected and mapped.

Abstract

This study was investigating the effect of sintering time (30 h, 32 h, and 34 h) on surface morphology of PbdopedBi-2223 oxides of superconductors prepared by the solid-state reaction method at 840 oC. Thesuperconductor was characterized by X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM).In the present study, phase purity, volume fraction, surface morphology, texturing, crystallinity, grainconnectivity and grain size of the bulk samples are found and compared with each other. The enhancementin the sintering time is confirmed that it will decrease Bi-2223 phase fraction and increase the impurity ofthe samples. SEM images shows that the sample has the best crystallinity, grain connectivity and largestgrain size. Based on the present results, it is conclude that the surface morphological is improving with theincreasing of the sintering time.

Abstract

In this study the samples of Bismuth ceramic superconductors were synthesized by the melt textured growth methods from a 2212 stoichiometric composition in order to obtain a large amount of pure Bi-2212. The effects of Pb substitution on the properties of Bi-based Bi2−xPbxSr2CaCu2Oy superconductor with x = 0, 0.2, and 0.4 were investigated by means of DC electrical resistivity measurements. It has been found that the hole-carrier concentrations per-Cu ion of the samples change independently of Pb content.

Abstract

Corrosion is a decline in the quality of the metal due to electrochemical reaction between the metal by a corrosive medium. One effort to reduce the rate of corrosion is by adding inhibitors. Organic inhibitors that can be used include antioxidants and vitamin C. To determine both the content of the test method is used Fourier Transform Infrared (FTIR) and phytochemicals. FTIR is a method to measure used to determine the group and the type of bonding of a compound based on the value of the wave number of a plant. Phytochemical screening is a test of the qualitative secondary metabolites biologically active compounds found in plants. In this study used a sample of red dragon fruit. The results of the analysis provide information regarding the types of biologically active compounds and levels of the active compound contained in the red dragon fruit.

Abstract

Study on hydrogen gas concentration to changes in voltage and resistance using semiconductor hydrogen gas sensor has been done. The system which has been designed will measure any changes in the voltage and resistance of the sensor automatically when the sensor is given a variation of concentration on hydrogen gas. On the condition of gas with low concentration, the sensor output voltage obtained worth 0:08 Volt and the sensor resistance value of 180 KΩ. On the increase in gas concentration causes an increase in sensor output voltage and a decrease in the value of resistanceStudi tentang pengaruh konsentrasi kadar gas hidrogen terhadap perubahan tegangan dan resistansi menggunakan sensor gas hidrogen berbasis semikonduktor telah berhasil dilakukan. Sistem yang telah dirancang akan mengukur setiap perubahan tegangan dan resistansi secara digital pada sensor saat diberikan variasi terhadap konsentrasi kadar gas hidrogen. Pada kondisi gas dengan konsentrasi rendah diperoleh tegangan output sensor senilai 0.08 Volt dan nilai resistansi sensor sebesar 180 KΩ. Pada peningkatan konsentrasi gas menyebabkan peningkatan tegangan output sensor dan sebaliknya terjadi penurunan pada nilai resistansi
