Abstract

A simple method to measure a solution refractive index using fixed mirror refractive optical fiber sensor has been investigated. The solution used are sugar and salt solution, with concentration varies from 1M to 5M. The diameter of polymer optical fiber used is 0.5 mm and light source used is LED (λ=676 nm). The sensor work based on light intensity modulation, sub jected to mechanical structure change of the fiber due to an applied force. The result showed that the concentration of sugar and salt linearly are related with their refractive indeces (R2=0,95006) and (R2=0,99858).

Abstract

It has been conducted a research about sea level rise (SLR) in surrounding Jawa island by using satellite altimetry data Topex/Poseidon, Jason-1 dan Jason-2 for period 2000 – 2010. Satellite altimetry is satellite which specially design for measuring dynamics of sea water. Those satellite lauched firstly in 1992 incorporation between National Aeronautics and Space Administration (NASA) dan European Space Agency (ESA). There are six locations for measuring SLR i.e. Jakarta, Semarang, Surabaya, Pangandaran, Jogjakarta dan Prigi. We choselocations based on alongtrack of satellite and near the big cities in Jawa island with dimension area around 0.5ox0.5o degrees. We found SLR rate for Jakarta (2.5 ± 0.24 mm/yr), Semarang (2.16 ± 0.20 mm/yr), Surabaya (2.72 ± 0.19 mm/yr), Pangandaran (0.71 ± 0.33 mm/yr), Jogjakarta (0.91 ± 0.38 mm/yr) and Prigi (1.3 ± 0.38 mm/yr). The average SLR rate for North coast is (2.46 ± 0.21 mm/yr) and for South coast (0.97 ± 0.36 mm/yr). This results are wellcorrelated with data from tide gauge stations.

Abstract

It has been done a research about separation of regional-residual anomaly in Gravity method. This research compares the result of three methods i.e. moving average method, polynomial method, and inversion method. The computer program is created using a computer programming Matlab 7. From three methods that have been made, the separation results are compared withresults of separation by using Upward Continuation method. From the results of these comparisons will be available an excellent program of regional-residual anomali separation. The results show that in polynomial method of the order 4 obtained similar contour to the separation by Upward Continuation Software. So that the output of this separation will be treated again with Grav2DC software. The output of this software is the density of rock Grav2DC of the studyarea. Processing results obtained the minimum error of 1.85% for the separation by polynomial method, while for the method of Upward Continuation obtained minimum error of 2.22%. The results obtained show that the separation of regional-residual anomali by polynomial method is similar to separation by Upward Continuation method.
