Development and Evaluation of Web GIS Application for Groundwater Management of Karanganyar Regency

The watershed is one of the ecological functional units in a region. The Rawa Pening Sub-Watershed, located in Semarang Regency and its surroundings, is the upper region of the Tuntang Watershed, which experiences periodic floods. Flood hazard disasters occur due to several contributing factors. This phenomenon significantly affects the residents in the Rawa Pening Sub-Watershed, particularly in the agricultural sector, specifically in the local paddy fields. With the development of Geographic Information Systems (GIS) in disaster management, it is possible to provide preliminary information on predicting flood hazard zones, particularly in the Rawa Pening Sub-Watershed. This study aimed to determine the most influential parameters and areas highly prone to flood hazards in the Rawa Pening Sub-Watershed. Nine parameters, including elevation, slope, curvature, precipitation, land use, soil type, distance to the river, Normalized Difference Vegetation Index, and Topographic Wetness Index, were analyzed based on their respective roles. The Analytical Hierarchy Process (AHP) and Ordered Weighted Averaging (OWA) techniques were employed to obtain the flood hazard map. The nine parameters were weighted according to a Forum Group Discussion. The results yielded a flood hazard map divided into five zones: very low (3451,64 Ha / 13,16%), low (5024,29 Ha / 19,16%), moderate (6049,35 Ha / 23,07%), high (7949,67 Ha / 30,31%), and very high (3750,93 Ha / 14,30%).

Karanganyar Regency, known for its captivating mountainous geography, possesses significant potential for geo-tourism development. Enhancing the visibility of the region’s tourist attractions on social media platforms is imperative to capitalize on this potential fully, thus increasing their allure. This study aims to analyze the marketing strategies employed on social media to bolster the appeal of geo-tourism attractions. This research gathers comprehensive and reliable data from various natural tourist locations and relevant agencies using qualitative methods, survey techniques, and interviews. Several notable natural attractions with considerable developmental potential are identified, including Grojogan Sewu, Grojogan Pringgondani, Parang Ijo Waterfall, Jumog Waterfall, Telaga Madirda, and Sapta Tirta Pablengan. Key areas that influence tourism development are identified to foster the growth of these tourist hotspots. These include enhancing marketing and promotional efforts for natural tourist attractions through Instagram, optimizing accessibility to these destinations, and improving facilities and infrastructure. By addressing these aspects, tourists are more likely to be enticed to visit the natural wonders of Karanganyar Regency. The results of this study are expected to reveal effective social media-based marketing strategies for promoting natural attractions on Instagram in Karanganyar Regency. Furthermore, evaluating these strategies will lead to discovering new insights and improvements for leveraging the full tourism potential of the region.

Determination of groundwater potential using geoelectricity in Tanah Bumbu, South Kalimantan

This survey was conducted to determine the distribution of groundwater in the Tanabumbu area of South Kalimantan. In this study, we aim to obtain the resistivity of soil layers using the Wenner geoelectric method and his one-pass, two-point dipole-dipole configuration. Field survey data were processed using RES2DINV software. Measurement data results are available in the form of 2D resistivity cross visualizations that are analyzed to determine groundwater distribution. In addition, we performed a comparative analysis of the accuracy of geoelectric measurement results using the results of data with different configurations. Based on the results of geoelectric measurements, we are able to find the aquifer location related to a high probability of groundwater.
