Abstract

Menurut laporan BPBD, terjadi longsor di daerah Babakan Madang. Saat mempelajari aspek kebencanaan yang terkait dengan gerakan tanah, lereng adalah salah satu komponen yang paling penting yang dibahas. Dengan mempertimbangkan tipe batuan, karakteristik lereng, dan data DEMNAS, tujuan penelitian ini adalah untuk menentukan kelas kelerengan dan arah lereng. Kelerengan dan arah lereng membutuhkan data DEMNAS, sedangkan tipe batuan membutuhkan pemetaan geologi yang akurat. Selanjutnya, data yang dikumpulkan dibagi menjadi beberapa kelas berdasarkan parameter yang telah ditetapkan. Analisis yang dilakukan menunjukkan bahwa zonasi kelas kelerengan berkisar dari sangat rendah hingga sangat tinggi. Penelitian ini memiliki lereng yang berbeda dari utara ke selatan, menunjukkan variasi yang signifikan di seluruh area. Selain itu, jenis batuan yang ditemukan juga diklasifikasikan berdasarkan kualitasnya, berkisar dari sangat baik hingga sangat buruk. Dalam konteks mitigasi bencana tanah longsor, penelitian ini memberikan wawasan yang lebih mendalam tentang hubungan antara kelerengan, arah lereng, dan tipe batuan. Penelitian ini diharapkan dapat membantu perencanaan dan pembangunan infrastruktur yang lebih tahan terhadap longsor. According to the BPBD report, a landslide occurred in the Babakan Madang area. When studying disaster aspects related to ground movement, slope is one of the most important components discussed. By considering rock type, slope characteristics, and DEMNAS data, the aim of this research is to determine the slope class and slope direction. Slope and slope direction require DEMNAS data, while rock types require accurate geological mapping. Next, the collected data is divided into several classes based on predetermined parameters. The analysis carried out shows that the slope class zoning ranges from very low to very high. This study has different slopes from north to south, showing significant variation across the area. Apart from that, the types of rocks found are also classified based on their quality, ranging from very good to very poor. In the context of landslide disaster mitigation, this research provides deeper insight into the relationship between slope, slope direction, and rock type. It is hoped that this research can help plan and build infrastructure that is more resistant to landslides.

Abstract

Cisauk district is located within the administrative area of Tangerang regency, Banten Province. The Cisauk district was originally part of the Serpong district, which experienced regional expansion. Initially, much of the land in the Cisauk district was agricultural land. However, as the population grew, its function changed to residential land, industrial trade, and services. In addition, this area in Tangerang regency is strategic as a buffer for the capital city of Jakarta. Therefore, with the increasing rate of population growth and the growth of residential areas or housing developments in the Cisauk district, the need for clean water is also directly proportional. Based on these problems, it is necessary to have training and mentoring activities in implementing clean water well-making activities, with the aim that clean water well-making activities are carried out by plans and methods that meet implementation standards and technical standards for making clean groundwater wells.  It is planned to construct a borehole well at a location identified as a productive aquifer zone based on the ADMT survey results. The borehole well will be designed to reach the optimum depth to penetrate the aquifer zone, providing a sustainable, clean water supply for the community of Cibogo Village, Cisauk District.

Abstract

Jakarta, the capital of Indonesia, is a coastal city shaped by geological and environmental processes over the past two million years of the Quaternary Period. The Jakarta Plain was formed by a mix of land sediments from the Cisadane and Citarum Rivers and marine sediments from the Java Sea. The southern region is a volcanic highland, while the city lies on lowlands with elevations ranging from 0 to 40 meters above sea level. Aims: to investigate the geological origin and sedimentary structure of the Jakarta Plain as a bay city situated between two major river deltas and to understand the implications of its geological development for spatial planning, environmental management, groundwater utilization, land subsidence, flood control, and coastal resource management, especially in the Jakarta Bay area, which features coral reef island ecosystems. Methodology and results: the research was conducted through field observations of geological outcrops and coral reef islands in Jakarta Bay, complemented by secondary data sources. The results indicate that the plain is filled by alternating layers of terrestrial and marine sediments, with strong geological connections to the surrounding Bodetabek region (Bogor, Depok, Tangerang, Bekasi). Conclusion, significance, and impact study: The study concludes that a thorough understanding of Jakarta’s sedimentary history is essential for mitigating geological risks and supporting sustainable urban development. Furthermore, Jakarta Bay’s coral reef islands hold considerable potential for tourism, underscoring the importance of integrated coastal and environmental planning based on sound geological insight.

Abstract

The research area is located in the Tuksongo area and its surroundings, Borbudur District, Magelang Regency, Central Java. Astronomically, the area is 110°10'21.8"– 110° 13' 39.0" East Longitude and 7°36'36.4"– 7° 38' 20.2" South Latitude. With an area of 30 km2, the mapping area has its own charm, especially from a geomorphological perspective. All geological aspects in the mapping area are closely related to intensive volcanic activity in the Oligocene to Miocene which was controlled by 3 ancient volcanoes, namely Mount Ijo, Mount Gajah and Mount Menoreh. Apart from that, recent volcanic activity such as Mount Sumbing also plays a role in forming the mapping area. Geomorphologically, in the mapping area there are four units, namely the Kerukbatur Lava Flow Ridge Geomorphological Unit, the Ngaglik Caldera Wall Geomorphological Unit, the Bejen Pyroclastic Flow Plain Geomorphological Unit and the Tuksongo Alluvial Plain Geomorphological Unit.

Abstract

Penelitian ini merupakan studi literatur yang bertujuan untuk menganalisis pengaruh infiltrasi terhadap tata guna lahan di Kelurahan Ulujami, Jakarta Selatan. Seiring dengan pesatnya urbanisasi dan pertambahan penduduk, juga perubahan fungsi lahan di wilayah perkotaan, kemampuan lahan untuk meresapkan air tanah cenderung menurun akibat meningkatnya luas permukaan tertutup, seperti bangunan dan jalan beraspal. Studi ini mengkaji berbagai sumber literatur dan data sekunder terkait pola penggunaan lahan, karakteristik hidrologi lokal, serta keterkaitannya dengan penurunan daya resap air tanah. Hasil studi menunjukkan bahwa alih fungsi lahan terbuka menjadi area terbangun berdampak sangat signifikan terhadap menurunnya kemampuan lahan dalam menyerap air hujan, yang dapat memicu penurunan muka air tanah dan peningkatan risiko banjir. Oleh karena itu, diperlukan strategi pengelolaan tata guna lahan yang berkelanjutan untuk menjaga keseimbangan antara pembangunan dan konservasi sumber daya air. Studi ini diharapkan dapat menjadi dasar pertimbangan dalam perencanaan tata ruang dan kebijakan lingkungan di wilayah urban seperti Jakarta Selatan. This research is a literature study aimed at analyzing the influence of infiltration on land use in the Ulujami Subdistrict, South Jakarta. In line with rapid urbanization and population growth, as well as land use changes in urban areas, the land's ability to absorb groundwater tends to decline due to the increasing extent of impervious surfaces, such as buildings and paved roads. This study examines various literature sources and secondary data related to land use patterns, local hydrological characteristics, and their correlation with the decrease in groundwater infiltration capacity. The results of the study show that the conversion of open land into built-up areas has a significant impact on reducing the land's ability to absorb rainwater, which may lead to a decline in groundwater levels and an increased risk of flooding. Therefore, sustainable land use management strategies are needed to maintain a balance between development and the conservation of water resources. This study is expected to serve as a basis for consideration in spatial planning and environmental policy in urban areas such as South Jakarta.

Abstract

Ketersediaan air baku yang berkelanjutan merupakan salah satu tantangan utama dalam pengelolaan sumber daya air, khususnya di wilayah urban dengan laju pertumbuhan penduduk yang tinggi. Kecamatan Jagakarsa, Jakarta Selatan, sebagai bagian dari wilayah perkotaan DKI Jakarta, mengalami peningkatan jumlah penduduk setiap tahunnya, yang berdampak langsung terhadap peningkatan kebutuhan air baku. Penelitian ini bertujuan untuk menganalisis kebutuhan dan potensi ketersediaan air baku di Kecamatan Jagakarsa dalam proyeksi sepuluh tahun ke depan. Metodologi yang digunakan meliputi analisis data sekunder dari Badan Pusat Statistik (BPS) terkait jumlah penduduk dan laju pertumbuhan, serta data ketersediaan air dari instansi terkait, dikombinasikan dengan pendekatan geologi teknik untuk mengevaluasi potensi sumber daya air tanah di wilayah tersebut. Perhitungan kebutuhan air dilakukan berdasarkan konsumsi rata-rata per kapita harian, sementara estimasi ketersediaan dilakukan dengan mempertimbangkan kapasitas potensi air tanah dan distribusi jaringan air baku eksisting. Hasil yang diharapkan dari studi ini adalah tersusunnya proyeksi kebutuhan air baku hingga tahun 2030 dan evaluasi kesesuaian antara kebutuhan dan ketersediaan, sebagai dasar perencanaan pengelolaan sumber daya air yang lebih efektif dan berkelanjutan di wilayah Jagakarsa.  The sustainable availability of raw water is one of the main challenges in water resource management, particularly in urban areas with high population growth. Jagakarsa Sub-District, South Jakarta, as part of the metropolitan area of DKI Jakarta, has experienced a consistent increase in population, which directly impacts the rising demand for raw water. This study aims to analyze the demand and potential availability of raw water in Jagakarsa Sub-District over the next ten years. The methodology involves the analysis of secondary data from the Central Bureau of Statistics (BPS) regarding population figures and growth rates, as well as data on water availability from relevant agencies. These are combined with an engineering geology approach to assess the potential of groundwater resources in the area. Water demand calculations are based on average daily per capita consumption, while estimates of availability consider the potential capacity of groundwater and the coverage of the existing raw water supply system. The expected outcomes of this study include a projection of raw water needs up to 2030 and an evaluation of the balance between supply and demand, serving as a foundation for more effective and sustainable water resource planning in the Jagakarsa region.
