Landslide is a natural disaster that commonly happen in Banjarnegara Regency. Spatial geodatabase is required to help understanding the landslide, planning for post-disaster recovery, even helping for prepare the upcoming disaster that may happen. The purpose of this reserach is for providing an orthophoto mosaic as high-resolution imagery and a Digital Surface Model (DSM), and compare it with Digital Model Model (DEM) generated from terrestrial surveying. The DSM and DEM were compared to see which method was the best to provide a precise spatial geodatabase in natural disaster spot, especially at Clapar's Landslide.

Tellurite glasses with compositions of 55TeO2 - (41- x) ZnO-2Bi2O3-2Na2O-xPbO where x = 1.0, 1.5, 2.0, and 2.5% mole (Pb:TZBN glasses) were prepared by melting the mixture at 900°C and quenched rapidly. IR spectra were recorded in the range 400 cm-1 and 4000 cm-1. Analyses were carried out to study the effect of PbO incorporation into the glasses to the shift the main absorption vibrational spectra. The results were then analysed in term of coordination number of Pb as well as the change in mass reduction.

Theoretical and experimental study of light propagation in acrylic triangle waveguides has been studied theoretically and experimentally aimed to obtain a light cone which can tunnel and bring the light to a certain place. Numerical aperture of light cones which have a length of 7 cm but different cross-section area have been measured using he-Ne laser (λ=632 nm) and the results were compared to those obtained theoretically and no significant different was observed.

Optical fiber sandwiched pad designed as a pressure mapping sensor has been configured and characterized. Optical fiber sensor was aligned to form a web-like configuration (x- y matrix). Several fibers were positioned to form lines parallel to y-axis while others are in parallel to x-axis. When a mass with a particular surface contour was loaded on the fiber pad, we have shown the dependence of the magnitude of light attenuation on the mass surface contour. Combining these light attenuation results we have successfully constructed a three dimensional contours showing the pressure distribution given by the mass to the fiber pad.

Geospatial Information is a important thing in this era, because the need for location information is needed to know the condition of a region. In 2015 the Indonesian government release detailed mapping in village level and their Parent maps Indonesian state regulatory standards set forth in Rule form Norm Standards, Procedures and Criteria for Mapping Village (NSPK). Over time Web and Mobile GIS was developed with a wide range of applications. The merger between detailed mapping and Web GIS is still rarely performed and not used optimally. OpenStreetMap (OSM) is a WebGIS which can be utilized as Mobile GIS providing sufficient information to the representative levels of the building and can be used for mapping the village.Mapping Village using OSM was conducted using remote sensing approach and Geographical Information Systems (GIS), which's to interpret remote sensing imagery from OSM. The study was conducted to analyzed how far the role of OSM to support the mapping of the village, it's done by entering the house number data, administrative boundaries, public facilities and land use into OSM with reference data and data image Village Plan. The results of the mapping portion villages in OSM as a reference map-making village and analyzed in accordance with NSPK for detailed mapping Rukun Warga (RW) is part of the village mapping. The use of OSM greatly assists the process of mapping the details of the region with data sources in the form of images and can be accessed for Open Source. But still need their care and updating the data source to maintain the validity of the data.

It has been done a cross-hole method of field laboratory geoelectrical resistivity to identify the wastewater in Grogol, Gatak, Delanggu, Jawa Tengah. Measurements were performed using McOHM 2119C-EL OYO Resistivity meter. The Anomaly of the object that has given of this research is wastewater. The data acquisition of cross-hole model use dipole-dipole geoelectrical configuration. The distance between the two boreholes is 3 m and spaced electrodes that used are 0,1 m; 0,2 m; 0,3 m and 0,4 m. The Data will be taken from the movement of saline water anomaly that mobiles on the ground and each taking every 4 days for 5 times of the data acquisition. A description of the result of the anomaly will be reviewed using RES2DINV 3.56software. The visualization of the movement of wastewater model on day 4th is at a depth of 0,4 m – 0,6 m at a distance x = 0,5 m - 2,5 m with resistivity 10 - 10,8 Ωm. On day 8th is located at a depth x = 0,5 m – 0,8 m, x = 0,5 m – 2,5 m with resistivity 10 - 14 Ωm. And on day 12th is located at a depth of 0,8 m – 1,2 m at a distance x = 0 m – 0,5 m, x = 2,5 m - 3,0 m and x =1,5m - 2,5 m with a resistivity of 12,4 - 15 Ωm.
