Abstract

Geothermal prospect in Cipari has been shown by spring who has a temperature of about 50°C and is categorized as a low temperature. The presence of spring on Cipari earth's surface is an indication of geothermal structures' existence on the surface and a geothermal system below the surface. Geophysical methods can be used for subsurface structures identification, one of them is the density method with gravity data. This study has an objective to identify the subsurface structures in Cipari geothermal potential area using GGMPlus gravity data. Terrain and Bouguer corrections were used to obtain Complete Bouguer Anomaly (CBA). Separation of regional and residual anomalies using Butterwoth and Bandpass filters. The rock contact boundary was obtained by the FHD method and geological structures such as faults were obtained by the SVD method. FHD and SVD results were used as information for 2D forward modeling. The ABL map shows anomalous contrasts in areas that have rock contacts and geological faults. The high anomaly in the center of the study area indicates the Cipari anticline. Data processing and analysis concluded that the area around the Cipari hot spring has anticline, several rock contacts, and normal fault structures. The fault in the study area is part of the geothermal system which is confirmed by GGMPlus data.

Abstract

Jeruklegi landfill has leachate management system that still potential for leachate infiltration in subsurface. Leachate contamination may occur if landfill activity is continuous and have an impact to local society. Leachate contamination is an environmental pollution man-made minor disaster clasified. This research is an early prevention step by identifying disaster source. Identification is done by analyzing leachate distribution in subsurface using geoelectrical method with Wenner-Schlumberger array. The result of data acquisition is resistivity which is processed to apparent resistivity. Apparent resistivity was modelled by inversion method that shows leachate contamination near surface by resistivity not least at 1 ohm.m. Leachate contamination was not found over 20 meters based on the lack of resistivity difference. This was confirmed by chemical test of bore well water that match to hygiene and sanitation standards. Keywords: leachate, resistivity, geoelectric, Wenner-Schlumberger.

Abstract

Cilacap region earthquakes often occur with more than 5 Richter Scale. With these seismic conditions, earthquake studies in the Cilacap region will always be needed. These studies usually only have output in form of map visualization spatially, however, they have not been compiled in a time series. This study attempts to include visualization of spatial data in the form of a time-series. The data visualization was presented in form of graphs and maps. Graphical visualization using line bar graph type by applying descriptive statistics tries to determine the earthquake’s magnitude fluctuation. The other visualization in form of Heatmap map analysis applying the Kernel Density method is interpolated earthquake magnitude spatial data. The data used in this research was retrieved from the USGS datasets between 1918 to 2021. The spatial boundaries were taken from -7.324 ˚S, 107.941˚E to -10.407˚S, 111.116˚E. The results of spatial data visualization using the heatmap techniques were then analyzed temporally using the Temporal function in the QGIS software. The results of temporal analysis within a year are then sequenced into a video which is displayed on the following link https://youtu.be/m3B7HkfI8qY. The descriptive statistical analysis shows that Earthquakes have magnitudes ranging from 3.3 to 7.58 with a mean of 4.58 and a mode of 4.4. Heatmap analysis shows the results of earthquake magnitude interpolation with high density, located in the south of Cilacap and south of Yogyakarta. Also, the spatiotemporal analysis results show that there is a change in location trends that have high earthquake magnitude density values

Abstract

In the rapidly developing digital age, websites have become indispensable for interaction, information dissemination and transaction. To improve the performance of web applications, choosing the right rendering technology is critical. Next.js is a framework designed to overcome React's limitations in server-side rendering. This study investigates the effectiveness of Client-side Rendering (CSR), Server-side Rendering (SSR), and Static Site Generation (SSG) on the Next.js-based Filmku website using the loading time method. The study concentrates on page loading speed, complete page rendering speed, and user experience. The authentication page takes 422 ms to complete the CSR process, which is 57.41% slower than the SSG finish time of 180 ms and 34.88% slower than SSR, which completes the authentication page in 274 ms. On the Profile page, SSG completes the page rendering process much faster, taking only 524 ms, which is 25.79% faster than SSR's completion time of 706 ms and even 13.75% faster than CSR's completion time of 608 ms. The SSG rendering method completed in 1,135 ms on the main page, which is 15.93% faster than the CSR completion time of 1,350 ms and 25.57% faster than the SSR completion time of 1,525 ms. It is evident that SSG has a faster rendering speed compared to the other methods. However, it should be noted that CSR may result in slower initial page load times. SSR can provide stable rendering times, but it can also burden the server as every client request is fully processed on the server.

Abstract

Spatial presentation of data can provide broader information about an event or a feature that can facilitate drawing conclusions, for example using webGIS. WebGIS development in Klaten Regency has been implemented to display school data using licensed tools, but no development has been carried out using open source tools so that it is easy to customize. So, the development of a webGIS prototype is needed for the management and assessment of school data in Klaten Regency using open source tools. The system development methodology used is the waterfall model, with the phases of requirements analysis, design, implementation, and testing. The system was developed using the PHP language framework Code Igniter 4, MySQL database, front-end development in displaying maps using Leaflet.js and OpenStreetMap libraries. Spatial data of sub-district areas in the form of polygons is displayed using JSON and AJAX technology. School spatial data is displayed in the form of location point markers with school profile pop-ups. Functionality testing is carried out using the black box testing method resulting in all features functioning according to their functions.
