Abstract

Desa Siron Krueng merupakan salah satu desa yang berada pada Kecamatan Kuta Cot Glie, Kabupaten Aceh Besar, Provinsi Aceh. Formasi yang terdapat pada lokasi penelitian terdiri dari Formasi Seulimeum (Qtps), Formasi Komplek Indrapuri (Tuic), Formasi Meucampli (Tlm) dan sedikit Formasi Batugamping raba anggota terumbu (Murlr). Metode yang digunakan pada penelitian ini berupa pemetaan geologi dan analisis petrografi (thin section) pada batuan beku. Tujuan penelitian ini yaitu untuk melihat kondisi litologi di lokasi penelitian, dan menginterpretasi sayatan tipis batuan yang berguna untuk melihat kandungan mineral dan untuk mengetahui petrogenesis batuan beku yang terdapat pada lokasi penelitian. Berdasarkan hasil penelitian yang telah dilakukan, litologi yang terdapat pada lokasi penelitian terdiri dari 3 satuan batuan yaitu satuan batupasir tufaan, satuan serpentinit, dan satuan andesit. Pada hasil analisis petrografi, mineral yang terdapat pada batuan beku di lokasi penelitian terdiri dari ; kuarsa, piroksen, hornblende, plagioklas, olivin, opak, dan gelasan. Petrogenesis batuan beku di lokasi penelitian terdiri dari batuan beku intermediet dengan jenis magma pada batuan yang bersifat basa dan termasuk kedalam jenis batuan beku vulkanik, serta batuan beku ultramafik dengan jenis magma pada batuan yang bersifat ultrabasa dan merupakan jenis batuan beku plutonik

Abstract

Kerentanan airtanah terhadap pencemaran dapat terjadi akibat adanya aktivitas manusia. Oleh karena itu, kualitas dan kuantitas airtanah perlu diperhatikan. Penerapan metode GOD (Groundwater Occurrence, Overlaying Lithology and Depth Of Groundwater) dilakukan untuk mengkaji kerentanan airtanah di Kota Banda Aceh, Provinsi Aceh. Metode GOD merupakan metode yang dilakukan dengan mengevaluasi tiga parameter yaitu jenis akuifer, jenis litologi diatas akuifer dan kedalaman muka airtanah. Penelitian ini bertujuan memetakan daerah yang berpotensi terjadi pencemaran berdasarkan tingkat kerentanan air tanah dengan menggunakan metode GOD, di Kota Banda Aceh. Hasil dari penelitian menunjukkan tingkat kerentanan airtanah intrinsik berdasarkan metode GOD berkisar pada nilai sedang sampai tinggi. Zona sedang berdasarkan metode ini ditunjukkan pada nilai indeks 0.45-0.5 yang mencakup beberapa daerah seperti Kuta Alam, Kutaraja, Meuraksa, Jaya Baru, Banda Raya, Lueng Bata, dan Baiturrahman. Dan daerah dengan indeks tinggi mencakup kecamatan Syiah Kuala dan Ulee Kareng dengan nilai 0.52-0.69. Kondisi litologi pada daerah penelitian menunjukkan tipe akuifer yang sejenis yaitu sistem akuifer aluvial. The vulnerability of contaminated groundwater caused by human activity. Thus, the quantity and quality of groundwater need more attention. The application of GOD (Groundwater Occurrence, Overlaying Lithology and Depth of Groundwater) methods is done for a review of groundwater vulnerability in Banda Aceh City, Aceh Province. The GOD method is a method by investigating three parameters, they are: type of aquifer, type of lithology above the aquifer, and depth of groundwater table. This study aims to map areas with potential contamination based on the level of groundwater vulnerability using the GOD method, in Banda Aceh City, Aceh Province. The result of the research shows that the level of intrinsic groundwater vulnerability in Banda Aceh by the GOD method range from moderate to high. Moderate groundwater vulnerability zone based on this method has an index value of 0.45 - 0.5 covers several areas, they are: Kuta Alam, Kutaraja, Meuraksa, Jaya Baru, Banda Raya, Lueng Bata, and Baiturrahman. And the high index value covers Syiah Kuala and Ulee Kareng with 0.52 - 0.69. The lithology of the studied area shows the same type of aquifer as an alluvial aquifer system. Keywords: groundwater vulnerability, GOD method, aquifer

Abstract

The shoreface deposits study commonly conducted to characterize the reservoir's physical properties carried out by surface geological data. The physical properties focused on pore space conditions controlled by sedimentary process and tectonic settings in Seulimum Formation. The method used as descriptive analysis and previous study of the area interested. The geological data showed shoreface environmental deposits that can be divided into two types of environmental deposits they are middle shoreface and upper shoreface deposits. These environmental deposits are proven by some features such as bioturbation with an abundant presence of Ophiomorpha in the second stop sites (total 5 stop sites). The first stop site indicates two kinds of environmental deposits by coarse sandstones and mudstones dominated facies presence in the specific beds. Mudclast and hummocky structures also present in the field observation that concludes complex environmental deposits during the quaternary period the formation. Based on characteristics of facies could suggest those sediment products deposited on shallow marine. These wave-dominated coasts generally have an excellent reservoir potential effect on shoreface sands that are laterally continuous and were orientated parallel to the shoreline.

Abstract

The Singkil Sub-district of Aceh Singkil District comprises alluvium deposits with a relatively low ultimate bearing capacity. The ultimate bearing capacity of the soil is closely related to the safety of a building. The important thing related to estimating the ultimate bearing capacity of the soil is in-situ soil investigation. This study aims to estimate the spatial distribution of soil ultimate bearing capacity using field test data in the Singkil Sub-district. Estimating ultimate bearing capacity is useful to provide an initial picture for various planning and infrastructure development activities in the study area. Twenty CPT in-situ tests have been obtained from various field works in Aceh Singkil Regency. Field data analysis, based on empirical methods, was carried out to obtain the value of the ultimate bearing capacity of the soil at the test location. Then, the estimated distribution of the maximum bearing capacity obtained was carried out. The zoning map of the distribution of soil ultimate bearing capacity in the study was developed from this research. This map can be used as a form or effort of disaster mitigation by various stakeholders involved in planning and building various infrastructure facilities in the Singkil Sub-district
