Abstract

The existences of several hot springs between Slamet volcano, Paguyangan, and Cipari Districts raised questions regarding their origin. Several studies have been conducted related to the hydrothermal system at the location. Subsequent studies are needed to understand the hydrothermal system at the research site for the sustainability and conservation of geothermal natural resources. This research has reviewed several previous studies plus the latest information on the origin of hot spring water with the help of deuterium (2H) and 18O isotopes. This study used geochemical analysis of hot springs (geothermal) and local meteoric water to obtain information on isotope values. This was used for the interpretation of the origin of geothermal water. This study also used regional geological analysis methods for the interpretation of the mechanism for the emergence of these hot springs. The results of the analysis informed that the origin of hot water was local meteoric water. The geological structure was weak enough to allow water from the geothermal reservoir to reach the surface and meteoric water into the reservoir.

Abstract

Meru Betiri National Park (TNMB) is a natural conservation area related to land use that impact on the environment. Land-use suitability with land capability is essential so that the impact of the geological environment that can occur can be reduced and controlled. The research aims to determine the aspects of environmental geology and zoning land capability for governance of TNMB. Geological aspects of the environmental order that support this research are morphology (slope), lithology, hydrogeology (river density), and land cover. Each aspect is a parameter in the Analytical Hierarchy Process (AHP) evaluation method. The weight of each parameter of the AHP evaluation result is 26% for slope, 19% for lithology, 11% for river density, and 44% for land cover. The result of overlay parameters yields a score of each zoning and is classified into 4 (four) zoning land capabilities for governance of TNMB. The land use zone for governance of TNMB is divided into high capability zones, medium capability, low capability, and very low capability. High and medium capability zones can be used as conservation of TNMB primary forests.

Abstract

Abstrak: Gerakan tanah (longsor) fenomena alam yang sering menimbulkan bencana dan kerugian besar baik dari segi harta benda, sarana dan prasarana, maupun nyawa manusia. Perhatian khusus diberikan pada zona bahaya longsor karena terkait dengan keselamatan masyarakat yang tinggal di sana, terutama dengan keadaan lingkungan alam di Indonesia, dimana faktor penyebab lingkungan geologi yang kompleks, topografi dan iklim sangat dominan. Beberapa wilayah Indonesia termasuk Kabupaten Purbalingga rawan longsor. Peta kerentanan longsor yang ada saat ini memiliki   skala   yang   besar   dan cakupan   wilayah   Kabupaten.   Penelitian   ini bertujuan untuk menentukan bobot parameter yang berpengaruh terhadap gerakan tanah serta memetakan zonasi kerentanan gerakan tanah pada lingkup kecamatan dengan skala yang lebih detail. Hasil dari peta zona kerentanan longsor skala kecamatan dapat menjadi acuan yang lebih aplikatif bagi pemerintah setempat untuk diterapkan sebagai panduan serta acuan dalam mengambil kebijkan tentang pemanfaatan lingkungan serta sebagai dasar mitigasi prabencana. Metode yang dilakukan adalah analisis data spasial dengan parameter kemiringan lereng, curah hujan, jenis batuan, tata guna lahan, struktur geologi, dan kerapatan sungai. Zonasi kerentanan gerakan tanah pada Kecamatan Karangjambu dibagi 3 (tiga), yaitu: zona kerentanan rendah dengan luas sekitar 20%, zona kerentanan menengah dengan luas sekitar 45%, dan zona kerentanan tinggi dengan luas sekitar 35%.Abstract:  Landslides are natural phenomena that often cause disasters and great losses in terms of property, facilities, and infrastructure, as well as human lives. Special attention is given to the landslide hazard zone because it is related to the safety of the people who live there, especially with the state of the natural environment in Indonesia, where the factors causing complex geological environments, topography, and climate are very dominant. Several areas of Indonesia, including the Purbalingga Regency, are prone to landslides. The current landslide susceptibility map has a large scale and covers the Regency area. This study aims to determine the weight of the parameters that affect ground motion and to map the zoning of ground movement vulnerability in the sub-district scope with a more detailed scale. The results of the sub-district scale landslide vulnerability zone map can be a more applicable reference for the local government to be applied as a guide and reference in taking policies on environmental utilization and as a basis for pre-disaster mitigation. The method used is spatial data analysis with parameters of rock type, geological structure, slope, rainfall, land use, and river density. Zoning landslide vulnerability in Karangjambu District is divided into 3 (three), namely: low landslide vulnerability zone with an area of about 20%, medium landslide vulnerability zone with an area of about 45%, and high landslide vulnerability zone with an area of about 35%.

Abstract

Longsor (gerakan tanah) merupakan peristiwa alam yang seringkali membawa bencana dan kerugian yang tidak sedikit, baik berupa harta benda, sarana dan prasarana maupun jiwa manusia. Kabupaten Purbalingga terutama di bagian utara sebagian besar tanah/batuannya dibentuk oleh batuan vulkanik yang tanah pelapukannya gembur, dan sebagian daerahnya berlereng terjal, sehingga pada musim penghujan mempunyai potensi untuk terjadi gerakan tanah yang dapat mengancam kelestarian alam dan keselamatan jiwa penduduk setempat. Hal tersebut harus mendapat perhatian khusus dari pemerintah, sehingga perlu dilakukan studi yang lebih detil agar kedepan bisa dilakukan mitigasi yang bersifat prefentif kedepanya. Pada pelaksanaan Peningkatan Kapasitas dilakukan sosialisasi atau penyuluhan guna meningkatkan kemampuan dalam akuisis data bencana. Pengabdian ini dapat mengoptimalkan sistem informasi kebencanaan di Kabupaten Purbalingga dalam menginformasikan peta rawan bencana dalam bentuk webGIS.

Abstract

Cekungan Air Tanah (CAT) Jakarta bagian utara yang termasuk kedalam Provinsi Daerah Khusus Ibukota Jakarta merupakan dataran aluvial dengan wilayah pertumbuhan penduduk dan industri yang sangat pesat. Aktivitas tersebut mengakibatkan pemanfaatan air bersih akan meningkat. Dampak yang ditimbulkan dari pemanfaatan air tanah secara berlebihan adalah adanya pencemaran air tanah berupa intrusi air asin yang dijumpai di daerah yang berbatasan dengan pantai ke dalam air tanah dangkal. Terdapat 4 Satuan yang berada pada geologi daerah penelitian dari tua ke muda yaitu, Formasi Tuff Banten (QTvb), Kipas Alluvium (Qav), Endapan Pematang Pantai (Qbr), dan Alluvium (Qa). Karakteristik air tanah pada daerah penelitian di analisis menggunakan data parameter fisik dan kimia air tanah. Secara umum pola aliran air tanah pada daerah penelitian berarah selatan – utara mengikuti kemiringan lereng. Dari hasil analisis fisik pada daerah penelitian didapatkan nilai Daya Hantar listrik bernilai 196,3 – 5640 μS/cm , untuk total dissolved solid (TDS) bernilai 131 – 3760 mg/L , dan untuk nilai pH bernilai 6,5 – 8,5. Selanjutnya hasil dari analisis kimia laboratorium yang dianalisis dengan menggunakan diagram stiff dan diagram piper, fasies air tanah pada daerah penelitian terdiri dari tigas fasies air tanah, yaitu fasies Ca-HCO3 , Na-HCO3, dan Na-Cl. Tingkat keasinan air tanah berdasarkan perhitungan menurut Revelle (Klasifikasi Simpson (1946) terbagi menjadi air tawar hingga air tawar terkontaminasi tinggi. Penelitian ini menunjukkan adanya persebaran air asin yang terdapat di wilayah lebih dekat dengan garis pantai.

Abstract

Mount Slamet is an active volcano in Java Island, Indonesia. Slamet volcanic rocks comprise various igneous and pyroclastic rocks, including basaltic lava, andesitic lava, pyroclastic rocks, and intrusions. Geochemical analysis of rocks in the studied area (301300 mE - 303300 mE and 9189400 mN - 9191400 mN) showed the presence of high calcium and iron elements. This geological study aims to determine the potential of material resources contained to be used for agricultural needs. The potential nutrients to be found such as P, K, Mg, Ca, Fe, Ti, Na, Mn, and Si with a DHL conductivity value of 0.0473 - 0.1318 mmhos /cm are classified as non-salinity, which is safe for soil improvement. Then the neutralization value relative to calcite is between 15.45 - 27.27 %, and the abrasion pH value is between 8.05 - 8.91. The agrogeological analysis shows that the Slamet volcanic rock in Baturraden area has good prospects as an ameliorant for highly weathered (acid) soils.
