Abstract

Abstrak. Penelitian ini bertujuan untuk mengkaji pengelolaan air tanah untuk mengantisipasi kekurangan air bersih di Desa Kampung Baru Kecamatan Tinangkung Selatan Kabupaten Banggai Kepulauan. Penelitian ini bersifat deskriptif analitik dengan metode cross sectional dan stratified purposife Sampling mengacu pada pola arah aliran air tanah (flownets). Pengumpulan data menggunakan instrumen kuesioner, wawancara mendalam dengan masyarakat pengguna air tanah menggunakan purposive sampling. Jumlah sampel konstruksi diambil semua sumur gali yaitu sebanyak 54 sampel. Sampel kualitas air tanah ditentukan berdasarkan peta flownets berjumlah 12 sampel. Untuk mengetahui tingkat pengetahuan dan perilaku sebagai bagian untuk merumuskan strategi pengelolaan air tanah diambil 30 responden. Analisis data menggunakan analisis univariat, laboratorium dan SWOT.  Hasil penelitian konstruksi sumur gali dari 54 sumur gali yang dimanfaatkan warga di Desa Kampung Baru berkisar 57% - 94 % tidak memenuhi syarat kelayakan dan berkisar 6% - 43 % memenuhi syarat kelayakan. Perbandingan nilai baku mutu kesehatan berdasarkan Peraturan Menteri Kesehatan Republik Indonesia Nomor 32 Tahun 2017 untuk kualitas fisik air sumur gali terdapat 8 (67%) sumur gali masih dibawah standar baku mutu air dan 4 (33 %) melebihi standar baku mutu air. Hasil analisis laboratorium menunjukkan bahwa parameter pH, kadar kesadahan, besi dan nitrat masih memenuhi standar baku mutu air, kecuali parameter pH terdapat 5 (42%) sumur gali di bawah standar baku mutu air. Parameter bakteri Escherecia coli dan total Coiform secara keseluruhan melebihi standar baku mutu yang dibolehkan. Hasil analisis SWOT diperoleh startegi agresif dengan menerapkan strategi Strength (S) dan Opportunities (O) (SO), yakni melakukan pengelolaan air tanah dan mata air berdasarkan Peraturan Daerah, meningkatkan pelayanan kebutuhan air bersih dengan memberi kewenangan kepada pengurus atau organisasi pengelolah air seperti PDAM, meningkatkan sarana dan prasarana air bersih, mengupayakan teknologi pengelolaan air tanah dan meningkatkan pengetahuan masyarakat tentang pencemaran air tanah serta meningkatkan perialaku masyarakat untuk mengantisipasi pencemaran air tanah.Kata Kunci: Air tanah, Konstruksi sumur gali, Kualitas air tanah, dan SWOT

Abstract

Airtanah menjadi salah satu sumber air yang sering digunakan untuk aktivitas manusia. Ketersediaan airtanah mulai terancam akibat aktivitas domestik. Peningkatan penggunaan airtanah yang berlebihan untuk aktivitas manusia dapat mengakibatkan ketidakseimbangan pada potensi airtanah sehingga terjadi penurunan potensi airtanah. Tujuan penelitian ini, yaitu mengetahui pola aliran airtanah, mengestimasikan ketersediaan airtanah statis dan dinamis, serta mengetahui kebutuhan air domestik di Desa Karanglewas Kidul. Penelitian ini menggunakan metode geolistrik, elektromagnetik (EM), pumping test, dan pengukuran Tinggi Muka Airtanah (TMA). Hasil penelitian terkait pola aliran airtanah daerah Desa Karanglewas Kidul menunjukkan bahwa airtanah cenderung mengalir menuju Sungai Logawa dan Jengok akibat pengaruh topografi. Ketersediaan airtanah secara statis di Desa Karanglewas Kidul terhitung sebesar 14.600.449.526 liter/tahun, sedangkan ketersediaan secara dinamis sebesar 296.879.619 liter/tahun. Kebutuhan air per orang di Desa Karanglewas Kidul mencapai 89,21 liter/hari, sedangkan kebutuhan domestik mencapai 169.450.826,6 liter/tahun.

Abstract

The study aimed to determine the level of pollution sensitivity associated with fertilization activities in agricultural land in two karst spring catchment areas (Beton and Guntur). The aquifer characteristics of these two springs differ; the Beton Spring has a more developed allogenic channel development, whereas the Guntur Spring has a less developed autogenic system. In this study, the COCKPIT-PLUS and Master Recession Curve (MRC) techniques are combined to define land use zoning and the degree of aquifer sensitivity to pollution. Field sampling and stakeholder interviews were also conducted to assess land management practices and pollutant concentrations in the springs. The results show that due to the influence of more intensive and varied land use, Beton Spring has a higher sensitivity to pollution, as evidenced by higher concentrations of nitrate, phosphate, and Escherichia coli. In contrast, lower pollution levels in Guntur Spring occur due to the narrower recharge zone area supported by a more consistent planting pattern. Various strategies, including vegetative restoration, drainage planning, land use regulation, and communicative education, were formulated using the DPSIR framework. Strategies are critical in areas with high sensitivity, such as the Beton and Jomblangan recharge zones, which also highlight the necessity of land use restrictions based on upstream-downstream interactions. This study emphasized the importance of adapting the protection plan for karst aquifer recharge zones in response to land use intensity and degradation. It proposes an evidence-based integrated management model that focuses on decreasing the effects of land degradation in tropical karst aquifer systems.

Abstract

In order to keep the ecosystem's water resources in balance and prevent a decline in their availability, wise use of clean water is essential. In particular, since groundwater is one of the sources of clean water, this needs to be done. Kapanewon Temon which is located on a coastal stretch that currently has a new airport, namely Yogyakarta International Airport (YIA), which has the potential to increase the need for clean water. This study aims to determine the status of groundwater carrying capacity in Kapanewon Temon, Kabupaten Kulon Progo. The method used in this research is a survey method with primary data supported by secondary data on various study objects regarding groundwater for clean water needs.The survey results were then analyzed descriptively qualitatively and quantitatively. In this case, the status of the carrying capacity of the Kapanewon Temon coastal ecosystem is in the safe category.

Abstract

The purpose of this study is to define the characteristics of the karst aquifer, which is approximated by the parameters of (1) degree of karstification (Dk) and (2) time series analysis (cross-correlation and auto-correlation). This research focuses on the Ngerong Spring, the largest spring in Rengel Karst, East Java, Indonesia. Pendant rain gauge RG-3M and HOBO U20L-02 water-level data loggers were installed over one year with a recording interval of 15 minutes. Furthermore, after one year of time-series discharge data was obtained, the discharge recession coefficient was applied to make the recession formula. It was then used to estimate the karstification degree scale from 1 to 10. The aquifer memory system and the spring response to rainfall events were analyzed by auto-correlation and cross-correlation. The results of this study indicate that the karstification degree (Dk) of the Ngerong Spring system is 4.8-5.0, with one laminar and one turbulent flow subregime type. The aquifer system comprises a subregime with turbulent and laminar flow, where the substantial role in groundwater discharge plays the subregime with laminar flow. Meanwhile, time series analysis shows that the capacity of aquifer storage in the Ngerong Spring is large enough. It has a memory effect for 26.41 days, followed by a rapid response to rainfall events within 8 hours. Compared with several other karst sites in Java, the Ngerong Spring aquifer has the youngest development level with the best storage and the slowest release.
