“…The research method used is field observation, consisting of geological and hydrogeological observations. These observations include the location of spring emergence, lithology and morphology descriptions, and spring discharge measurements [12,13]. Secondary data collection is carried out first, which is the initial data, and becomes a reference in field observation and for mapping geological and hydrogeological conditions.…”

“…Basically, due to its compact rock, limestone is impermeable. However, the existence of fractures or dissolution holes within it allows limestone to act as a good aquifer [12]. In general, these springs occur from fractures or from dissolution holes of rocks and due to contact with rocks that have much lower permeability, such as claystone, and then these springs are suspected as contact springs.…”

“…This aims to find the relationship between the springs' occurrence and its geological conditions through data presentation and field observation mapping in the study area. Furthermore, this data can also serve as a basis for mapping groundwater potential zones that can provide a water backup in case of drought, where springs are one of the parameters for groundwater availability [5,10,11,12].…”

Springs are one of the water sources which can be used to meet the water needs of the community. Springs can be the main reliable source of water during the dry season in areas experiencing drought such as Kupang. This study aims to present observational data at the research area to find the relationship between the occurrence of springs and the geological conditions using field observation method for mapping the spring occurrence and its geological conditions. The results shows that there are 23 springs exist in the study area. The emergence of springs is generally found in limestone, which are 11 springs, then in conglomerate with 4 springs, 3 springs in the claystone, 3 springs in sandstone, 1 spring in schist, and 1 spring in alluvial. Based on the morphology, 8 springs found on hillsides, 8 springs at the foothills, 6 springs in the valley, and 1 spring on the alluvial plains. The largest discharge is 110.98 ℓ/s appears in limestone at the foothill (break of slope). Meanwhile, the spring with the smallest discharge, 0.04 𝓁/s, is located in claystone on the hillside. But most of all, the springs occurrence are related to fractures and dissolution holes in rocks.

Perubahan iklim saat ini memberikan dampak global, upaya adaptasi dilakukan dalam meminimalisasi dampak yang ditimbulkan. Kabupaten Kepulauan Sangihe adalah salah satu daerah di Sulawesi Utara yang dalam proyeksi BMKG mengalami penurunan curah hujan dengan kategori penurunan tinggi, yang akan mempengaruhi ketersediaan air bersih bagi masyarakat. Penelitian ini bertujuan untuk mengembangkan model adaptasi perubahan iklim dalam menghadapi potensi krisis air bersih di Kepulauan Sangihe pada masa mendatang. Metode yang digunakan adalah telaah literatur, identifikasi kondisi daerah dan pemodelan desalinasi air laut metode sea water reverse osmosis (SWRO) menggunakan software Toray Design System (DS) 2. Hasil penelitian menunjukkan Kabupaten Kepulauan Sangihe berisiko pengurunan ketersediaan air bersih ditinjau secara kondisi litologi, proyeksi iklim, dan kinerja jasa lingkungan penyedia air. Pemodelan SWRO yang menggunakan konfigurasi single pass two stage dimodelkan mampu memenuhi kebutuhan air bersih penduduk pada proyeksi tahun 2050 dengan debit air laut yang masuk 1,34 m3/detik dan air bersih dihasilkan 0,67 m3/detik.

“…Batuan Gunungapi Tengger (Qyt) terdiri dari tuf pasiran, tuf batuapung, tuf abu, aglomerat, sedangkan Tuf Malang (Qytm) terdiri dari tuf batuapung, tuf pasiran, tuf breksi, tuf halus, serta tuf lapili. Setting geologi Desa Jabung menyebabkan perbedaan potensi air tanah (Prastistho et al, 2018) di beberapa dusun, sehingga ada dusun-dusun yang memiliki potensi air tanah yang baik dan ada dusun-dusun yang mengalami kekeringan akibat potensi air tanah yang kurang baik.…”

Desa Jabung yang berada di Kecamatan Jabung, Kabupaten Malang memiliki potensi air tanah yang beragam. Penelitian menggunakan metode geolistrik Vertical Electrical Sounding (VES) dilakukan di beberapa dusun di Desa Jabung yang kesulitan air untuk memetakan potensi air tanah di dusun-dusun tersebut. Pengukuran VES dilakukan di Dusun Boro Lor, Dusun Gunung Kunci, Dusun Umpak, dan Dusun Mindi, dengan 1 titik referensi yang diukur di sebelah sumur bor milik Pemerintah Daerah. Hasil analisis VES di 4 dusun menunjukkan lapisan akuifer berupa lapisan batupasir dengan resistivitas 25,8-41,7 Ωm. Ketebalan akuifer beragam dari 4,6 meter hingga 30,1 meter. Kedalaman akuifer juga berbeda-beda dari kedalaman 40,6 meter hingga kedalaman 68,6 meter.
