Zonasi Kerentanan Air Tanah Pada Bentang Alam Karst Dengan Sistem Informasi Geografis Sebagai Dasar Penyusunan Tata Ruang

Abstract: Bentang alam karst memiliki karakter morfologi, geologi, hidrogeologi dan lingkungan hayati yang berbeda dibandingkan dengan bentang alam lainnya. Kondisi lahan di atas permukaan tanah pada bentang alam karst pada umumnya kering dan kritis, sedangkan di bawah permukaan tanah terdapat potensi sumberdaya air yang sangat berlimpah. Lokasi kajian terletak di Sub Daerah Aliran Sungai (Sub DAS) Alang, Kabupaten Wonogiri. Tujuan kajian adalah menentukan zona kerentanan air tanah dengan menggunakan metode APLIS (Altit… Show more

“…A study related to groundwater pollution in Medan City is needed with the study location around the Terjun landfill area, Medan Marelan sub-district. The APLIS method with the results of groundwater vulnerability zoning research shows that the potential vulnerability of groundwater in the research area is divided into 4 classes, namely very low, low, medium, and high [5,6,7]. This method can be considered as a new branch of studies on aquifer calculations using remote sensing and GIS [8,9].…”

“…Peanut (A. hypogaea L.) cultivated on lime soil which is poor in nutrients requires the addition of fertilizers to increase yields (Wijanarko & Rahmianna, 2015). The dependence of calcareous soil areas on chemical fertilizers has a negative impact on the environment including contamination of groundwater (Wuryanta, 2019). Therefore, an alternative biological organic fertilizer which has the adaptability on unfavorable environment and can increase crop yields, such as peanuts (A. hypogaea L.) var.…”
