Geographical location owned by Situbondo Regency has a coastal area, which could have the potential for sea water intrusion. Therefore, this study aims to explore water resources, namely groundwater in a coastal area of ​​Situbondo Regency - Banyuwangi Regency, which can be used to see the feasibility of life, especially for humans and animals. This research was conducted by sampling groundwater or well water using 3 parameters, namely TDS, pH, and salinity. After measuring the air content using TDS and pH parameters, ground or well water content, it is still suitable for use with a value range of 746 to 1170 mg/L for TDS, and 6.27 to 7.91 for pH content. Meanwhile, the salinity parameter can deny that the area measured in the study experienced sea water intrusion, but the value is not too high, namely 2 to 4 ‰. Then, for future improvements, it is necessary to carry out further research along the road from Situbondo District - Banyuwangi Regency to obtain a broader picture.

Coastal Region of Kangkung, Kendal Regency, Central Java Province is one of the areas that experiencing water in the dry season. Groundwater exploitation is one way solution to meet the water needs for people in the area, especially in the dry season. Therefore it is necessary to study potency of ground water in coastal area of Kangkung. The research was  conducted to determine the potential of ground water in the confined aquifer in the Coastal Region of Kangkung, Kendal District which is expected to be utilized as a source of water to meet the needs of local communities. The method used in this research is  descriptive analysis to describe the condition of aquifer, however some things are delivered quantitatively. The aquifer condition was obtained from the interpretation of geoelectricity (resistivity) data supported by geological and hydrogeological observation data and pumping test data as secondary data. Groundwater quality analysis and simple hydrochemical analysis is with Chlorida - Bicarbonat Ratio (CBR) method to know the possibility of sea water intrusion. The results showed that the aquifer in the coastal area of Kangkung has the potential of 29.13 lt / sec ground water discharge which can be utilized to meet the needs of clean water 18,800 people. Although it is adjacent to the sea, the groundwater in the study area does not undergo sea water intrusion. Groundwater quality in this location is qualified as raw drinking water according to SK Menkes No, 492/Menkes/Per/IV2010 tentang Persyaratan Kualitas Air Minum. Keywords: ground water, geoelectric, intrusion  Wilayah Pesisir Kangkung, Kabupaten Kendal Provinsi Jawa Tengah merupakan salah satu daerah yang pada musim kemarau mengalami kekeringan.

Sea Water Intrusion in Tugu Coastal Area of Semarang City Based on Resistivity and Hydrochemical Tugu Coastal Area is one of the coastal areas in Semarang City, Central Java Province that continues to grow. Although the clean water network from the  Local Water Supply Utility is available, groundwater is still used to meet the water needs of the community.  Some of the groundwater in the area is brackish to salty conditions as the result of sea water intrusion process. The research aims to determine configuration of aquifers which have been intruded with sea water in Tugu Coastal Area, Semarang City, so that groundwater exploitation from the aquifer can be avoided. The method used in this study was descriptive analysis, in which the condition of aquifers was based on interpretation of resistivity data. Simple hydrochemical facies analysis using the Trilinier Piper Diagram method is carried out to detect sea water intrusion. The results of the study indicated that aquifers in the Coastal area consisted of several layers. Aquifer which has been intruded with seawater is located on the north side of the Semarang - Kendal highway, both for confined and unconfined aquifers. The depth of confined aquifer which is intruded by sea water reaches 50 - 75 m below the local land surface. While the unconfined aquifer depth is up to a depth of 6 m below the local land surface. Wilayah Pesisir Tugu, Kota Semarang, Provinsi Jawa Tengah merupakan salah satu daerah pesisir di Kota Semarang yang terus berkembang.

The important issue relating to water resources is sea water intrusion (SWI) phenomena. Nowadays, the phenomena has become serious problem in the urban coastal area. Groundwater as main sources for domestic usage cannot be used again because of its salinity.Cilacap as one of urban coastal area also face the problem. In 1977 SWIwas detectedand experienced significant developmentsin 1996,This research was conducted to: (1) analyze agroundwater vulnerability to the SWI; (2) determine adistance and adepth theinterface; and (3) analyze relationship of the groundwater vulnerability to the interface depth.It was performed an analysis of the groundwater vulnerability to the SWI using the method of GALDIT, whereas the distance and depth of the interface was determined using the method of DupuitGhyben-Herzberg. The linkage analysis of the groundwater vulnerability to the depth of the actual interface was conducted by quantitative descriptively.The results showed that the distance from the shoreline was the most determined factor of the groundwater vulnerability to the SWI, the closer to the shoreline the more swallow the depth of the interface.  It existed the relevance between the vulnerability level of groundwater to the SWI with the depth of actual interface. The regions with low level of vulnerability had deep interface depth, whereas the regions with moderate level of vulnerability had swallow interface depth.  Nevertheless, the SWI has not yet affected the groundwater in people wells because of its depth that was not yet exceeded of 25 m.so that this depth can be used as a reference in digging wells in the research area++

Abstract The location of Talangagung Village is close to the Final Disposal Area, where the area has the potential to carry out groundwater pollution. Therefore, this study aims to explore water resources, namely groundwater in Talangagung Village, which can be used to see the feasibility of life, especially for humans and animals. This research was conducted by taking samples of soil or well water using measurement parameters in the form of Total Dissolved Solids (TDS). After measuring the air content using TDS measurement, ground or well water content, it is still suitable for use with a value range of 166 mg / L. Then, for future improvements, it is necessary to take more samples in the village area. Talangagung and add to measurement parameters, and get a wider pictureAbstrakLetak Desa Talangagung berada dekat dengan Kawasan Tempat Pembuangan Akhir (TPA), yang mana kawasan tersebut memiliki potensi untuk terjadinya pencemaran air tanah. Maka dari itu, penelitian ini bertujuan untuk mengeksplorasi tentang sumber daya air yaitu air tanah di Desa Talangagung, yang bisa digunakan untuk mengetahui kelayakan kehidupan, terutama untuk manusia dan hewan. Penelitian ini dilakukan dengan pengambilan sampel air tanah atau air sumur dengan menggunakan parameter pengukuran berupa Total Dissolved Solid (TDS). Setelah dilakukan pengukuran pada kandungan air dengan menggunakan pengukuran TDS, kadar air tanah atau sumur, masih layak untuk dikonsumsi yaitu dengan rentang nilai sebesar 166 hingga 270 mg/L. Lalu, untuk perbaikan di masa mendatang, perlu diadakan pengambilan sampel yang lebih banyak lagi di daerah Desa Talangagung dan menambah parameter pengukuran, supaya mendapatkan gambaran yang lebih luas.

Sea water intrusion (SWI) has been widely recognized as a global problem, significantly influencing coastal aquifers, mostly through reduced water quality and agricultural production indicators. In this paper, we present the outcomes of the implementation of two independent real-time monitoring systems, planned and installed to get insights on groundwater dynamics within the adjacent coastal aquifer systems, one located in the Neretva Valley, southeastern Croatia, the other located south of the Venice lagoon, northeastern Italy. Both systems are presented with technical details and the capacity to observe, store, and transmit (Neretva site) observed values in real-time. Analysis of time series reveals the significant influence of the sea level oscillations onto the observed groundwater electrical conductivity (EC) and piezometric head values, while precipitation rate is detected as a driving mechanism for groundwater parameters in shallow geological units. The installed monitoring systems are shown to be of great importance to provide qualitative and quantitative information on the processes influencing groundwater and surface water dynamics within two coastal systems.
