Abstract

Infiltration is an important process in a hydrological system and acts as a medium for air infiltration into the soil. The process of infiltration in soil can be influenced by several factors, namely, rainfall, vegetation, land slope, land use, and soil moisture. Apart from this, other factors such as groundwater level and soil permeability also have an influence on the infiltration process, both of which are related to each other in terms of the rate of infiltration or air infiltration into the soil. If the infiltration process is disrupted, it results in the pooling of air on the ground surface, which affects the hydrological system. It is necessary to know how factors such as groundwater levels and soil permeability influence the infiltration rate. Based on this, the aim of this research is to determine the relationship. between infiltration rate, groundwater level, and soil permeability and their influence. The research method was carried out by taking data from direct groundwater level measurements and infiltration rate measurements, as well as samples for soil permeability analysis. Then an interpretation of the data obtained is carried out and presented in a map of the infiltration zone and soil permeability zone. The research area in Tajur Village has 2 infiltration zones, namely the slow-medium zone and the medium zone with medium and rather fast soil permeability and low-medium groundwater depth.

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.

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.
