Abstract

Penelitian terletak pada daerah Kecamatan Ciater,Kabupaten subang, Provinsi Jawa Barat dimana menurut BNPB memiliki tingkat resiko bencana yang tinggi salah satunya bencana gerakan tanah atau biasa biasa disebut tanah longsor. Kemiringan lereng merupakan salah satu faktor yang menyebabkan terjadinya gerakan tanah, Tujuan dari penelitian ini perlu diketahui kemiringan lereng mana yang rawan terjadinya gerakan tanah serta tingkat kerawanannya. Kemiringan lereng akan dibagi menjadi beberapa kelas berdasarkan persen kemiringan yang dimana akan di tumpang tindih dengan data kejadian gerakan tanah dengan menggunakan SIG. hasil dari penelitian adalah terdapat tiga kelas kemiringan dan 12 titik kejadian gerakan tanah dimana kemiringan 15-30% memiliki kerawanan tinggi sedangkan yang lainnya rendah. The research is located in the Ciater District area, Subang Regency, West Java Province which according to BNPB has a high level of disaster risk, one of which is a landslide disaster or commonly called a landslide. The slope of the slope is one of the factors that causes ground movement. The aim of this research is to know which slope is prone to ground movement and the level of vulnerability. The slope will be divided into several classes based on the percent slope which will be overlapped with the ground movement data using GIS. the results of the study are that there are three classes of slope and 12 points of occurrence of ground motion where the slope of 15-30% has a high vulnerability while the others are low.

Abstract

Water catchment areas in residential areas or in the process of development are very important. The need for water resources that are used to meet the basic needs of personal life as well as development needs that are still growing really need water in the process of infrastructure development Soil type is one of the factors that determines water catchment areas. Soil samples were taken in the study area and then tested in the laboratory to determine the physical properties and classify the types of soil present. The results of the research are that the type of soil in the study area based on USCS is of poor gradation and the type of soil is based on PU No. 02/2013 has a score of 5.

Abstract

Abstrak Peningkatan aktifitas pembangunan dan urbanisasi di Jakarta Selatan telah meningkatkan pengambilan air tanah. Pengambilan air tanah secara terus menerus dengan pengelolaan yang buruk dapat menyebabkan terjadinya penurunan muka air tanah dan memicu terjadinya penurunan permukaan tanah secara berkelanjutan. Oleh karena itu, dibutuhkan suatu kajian mengenai hubungan penurunan permukaan tanah dengan penurunan muka air tanah yang terjadi di Jakarta Selatan. Penelitian ini dilakukan dengan menggunakan data sekunder berupa data log bor untuk mengetahui litologi bawah permukaan, data pengukuran penurunan tanah dengan metode geodetik GPS, dan data level muka air tanah pada sumur pantau di Jakarta.  Hasil kajian menunjukkan bahwa endapan sedimen permukaan didominasi oleh lapisan lempung yang masih berada dalam kondisi belum terkonsolidasi dan relatif menebal ke arah utara dengan ketebalan lebih dari 300 m. Kondisi ini memperlihatkan bahwa lapisan sedimen di Jakarta masih mengalami proses kompaksi sehingga secara alamiah terjadi penurunan permukaan tanah.. Penurunan permukaan tanah di Jakarta Selatan memiliki korelasi yang cukup kuat terhadap penurunan muka air tanah yakni sebesar 0,504 yang berarti memiliki derajat hubungan korelasi cukup kuat sebesar 50,4 %. Abstract Increased development activities and urbanization in South Jakarta have increased groundwater extraction. Continuous withdrawal of groundwater with poor management can cause a decrease in the groundwater level and trigger a subsidence. Therefore, a study is needed regarding the relationship of land subsidence with the decrease in groundwater levels that occur in South Jakarta. This research was conducted using secondary data in the form of drill log data to determine subsurface lithology, land subsidence measurement data using the GPS geodetic method, and groundwater level data in monitoring wells in Jakarta. The results of the study show that surface sediment deposits are dominated by a layer of clay which is still unconsolidated and relatively thickened to the north with a thickness of more than 300 m. This condition shows that the sediment layers in Jakarta are still undergoing a compaction process so that naturally subsidence occurs in the soil surface. Subsidence in the land surface in South Jakarta has a fairly strong correlation with the decline in the groundwater level, which is equal to 0.504, which means it has a fairly strong degree of correlation of 50.4%.

Abstract

Daerah penelitian berada di Desa Mokaha, Kecamatan Jatinegara, Kabupaten Tegal, Provinsi Jawa Tengah. Intensitas curah hujan daerah penelitian termasuk golongan cukup tinggi dan berada pada kemiringan lereng yang curam. Oleh karena itu akan sangat penting dalam penelitian untuk menentukan zona gerakan tanah pada lokasi penelitian dimana menjadi tujuan dari penelitian ini dengan menggunakan SIG. Dengan menggunakan peta dasar berupa peta Topografi daerah penelitian dan peta administrasi. Tujuannya agar penelitian dapat membuat peta – peta yang terdiri dari peta litologi, kelereng, kerentanan tanah, tata guna lahan, dan curah hujan yang dapat digunakan untuk mengetahui zona gerakan tanah dan diakhiri dengan pembuatan peta zona evakuasi. Metode penelitian menggunakan klasifkasi SNI merupakan suatu metode yang digunakan untuk menghitung dan menyajikan kecenderungan terjadinya bencana. Litologi pada lokasi penelitian terbagi menjadi 3 (Tiga) satuan batuan Lereng pada daerah ini dibagi 3 (Tiga) kelas yaitu 0 – 25%, 25 – 40%, >40%. Distribusi curah hujan tahunan periode 2018 lokasi penelitian berada pada 1000 – 2000 mm/tahun. Tata guna lahan pada lokasi penelitian terbagi menjadi 7 (tujuh) kelas. Pada daerah penelitian ini terdapat empat 5 (lima) zona kerentanan Gerakan Tanah

Abstract

Geothermal resources can be explored with aerial photographs followed by surveys and analysis of geological, geochemical and geophysical data as well as shallow drilling. This research was conducted to determine the potential of geothermal resources using a camera capable of capturing infrared rays from objects and photo targets.Geothermal exploration is generally carried out with an initial survey using remote imagery and aerial photography techniques. Taking photos using a tool equipped with a Thermal Infrared Sensor (TIRS), namely a camera equipped with Forward Looking InfraRed (FLIR).The initial survey in this study was conducted at five locations of geothermal springs in the Sangkanhurip area, Kuningan, West Java. From these five locations using FLIR cameras detected geothermal resources with hot spring temperatures between 30 to 40 degrees Celsius.To find out the types of rocks that exist, a geological survey was carried out to make a geological map. The data and information obtained are then analyzed to obtain a map that displays geology with surface temperature data in the study area.This map can be utilized by companies interested in exploring and producing geothermal energy for use as a source of energy for Geothermal Power Generation (PLTP). Further analysis can be carried out with the Geochemical Method for predicting subsurface temperature. This discovery fulfills the research objective of detecting geothermal resources using infrared rays.

Abstract

Remote sensing using satellites is an efficient and successful alternative for conducting geomorphological studies as important earth information. Known as a tourist area for its beaches and natural water baths. making the research location in the Mandolang District, Minahasa Regency, North Sulawesi Province important to research. In this study, a different approach to geomorphological studies was used: DEM data for 3D analysis was used to see various geomorphological images. Bird's eye views from a variety of locations and directions can be provided by the 3D DEM model, which can also obtain height and slope information from Topographic Maps and Slope Maps. The results of the map analysis are then used to produce a descriptive Geomorphological Map where the research area is dominated by a height of 175-350m above sea level and based [19] classification. The research area has three geomorphological units: 21% covers plains with height differences 0-50m and steepness 0-15%; 63.2% covers waves with height differences 50-200m and steepness 15-45%; and 63.2% covers hilly area with height differences 350-500m and steepness more than 45%.
