"Air tanah dangkal masih menjadi sumber utama bagi masyarakat untuk memenuhi sumber daya air. Skripsi ini membahas tentang ketersediaan airtanah dangkal yang diukur dengan kedalaman muka airtanah, kualitas, dan ketersediannya sepanjang tahun. Penelitian ini melihat bagaimana hubungan ketersediaan tersebut dengan kondisi fisik dan sosial, yaitu geologi dan penggunaan tanah. Selain itu, dilihat juga bagaimana masyarakat di wilayah ini memanfaatkan airtanah tersebut. Hasil dari penelitian ini adalah ketersediaan airtanah dangkal di wilayah penelitian memiliki kaitan dengan geologi pada kedalaman dan penggunaan tanah pada kualitas. Sedangkan dalam pemanfaatannya, masyarakat akan memanfaatkan airtanah sesuai dengan ketersediannya. Bila ketersediaan baik, maka masyarakat akan menggunakannya untuk semua kebutuhan. Pemanfaatan akan menurun seiring dengan menurunnya ketersediaan.

Shallow groundwater still be the main resources for society to comply water resources. Focus of this study is about shallow groundwater availability which is measured by depth of groundwater level, its quality, and its availability year around. This study observe how is correlation between groundwater availability with its physical and social condition, they are geology and landuse. Moreover, observation also about how the society in that area utilize the groundwater itself. Result of tfrom this study is groundwater availability in that area have relations with its geology in depth into groundwater and landuse in water quality. Meanwhile for its usage, society will utilize in accordance with its availability. If the availability is good, the society will utilize for all domestic usage. This usage will decrease if the availability decrease too."

"Gunung Agung is a stratovolcano type of volcano which has a height of 3,142 masl and is located in Karangasem Regency, Bali Province. At the end of 2017, Mount Agung's volcanic activity increased until it finally erupted several times in October to December. The government has prepared refuge pockets at the foot of Mount Agung, in areas that are not directly affected by eruption. There are 19 drilling plan points that will be carried out to meet the raw water needs at the evacuation site. This paper presents the groundwater recharge potential including the distribution of water sources, Hydrogeological conditions and the magnitude of groundwater recharge potential at hillside of Mount Agung and the surrounding area. The method used in this study is a field survey, calculation of potential recharge, analysis and evaluation of hydrogeological conditions, distribution of water sources and calculation of potential groundwater recharge. Groundwater at the foot of Mount Agung has the potential to be utilized and developed mainly to cover raw water needs in several refugee locations, namely in the Districts of Sidemen, Abang and Karangasem. The result of the analysis is that the largest groundwater potential is in Kubu Sub-District, namely 97,560,207 m3 / year, with a position that is relatively susceptible to primary hazards and secondary to Mount Agung eruption. For locations that are relatively safe and reachable in the area, they are in Tianyar, Sukadana, Baturinggit, Kubu, and Tulamben Villages, all of which are on the coast of the sea. These results are expected to be used by local governments in an effort to deal with the provision of water from the impact of the eruption of Mount Agung."

"Suatu kajian tentang kemungkinan adanya sistim mata air di lingkungan kampus UI Depok telah dilakukan dengan melakukan pengukuran geolistrik tahanan jenis. Pengukuran dilakukan dengan menggunakan konfigurasi elektroda model Schlumberger. Dengan mengukur parameter-parameter arus I dan tegangan V serta jarak antar elektroda, diperoleh harga variasi tahanan jenis lapisan tanah dan ketebalannya pada setiap titik sounding. Pengolahan data dilakukan dengan software Res1D Modeling dan Grapher menggunakan komputer PC. Pengukuran hanya dilakukan pada 8 titik sounding, dengan panjang bentangan kabel arus AB/2 hanya mencapai ± 100 meter. Mapping resistivity tidak penulis lakukan. Dari ke delapan titik sounding tersebut diperaleh suatu gambaran estimasi tentang sebaran lapisan akifer. Lapisan ini berada pada kedalaman ± 20 m di daerah FT dan FISIP, mendangkal menjadi ± 10 m di sekitar FMIPA dan FILM, dan makin mendangkal lagi menjadi ± 5 m di lingkungan Politeknik. Kedalaman lapisan ini penulis hitung dari permukaan tanah. Dari gambaran ini ada kemungkinan lapisan ini munculltersingkap di sekitar Politeknik. Dan ini bisa berpotensi menjadi mata air yang diduga ada di sekitar danau antara FMIPA dan Politeknik."
