Abstract

The small island has a very unique hydrological characteristics. The unique character are low rainfall, rain catchment narrow and high vulnerability to seawater intrusion. This study aims to (1) analyze the groundwater hydrogeochemistry facies in Panggang Cay and (2) to analyze the evolution of groundwater hydrogeochemistry in Panggang Cay. Data used include major element analysis results of the groundwater samples taken from the study site. Hidrogeochemistry fasies of groundwater determined the type of diagram analysis stiff, while the analysis of the hydrogeochemistry evolution of groundater analyzed using piper diagram. Groundwater hydrochemical facies in Panggang Cay is MgCl2 with hydrogeochemical evolution of CaCO3 into MgCl2. The evolution of hydrogeochemistry fasies that occur indicate the sea water intrusion process.

Abstract

AbstractSiklon tropis cempaka yang terjadi pada tahun 2017 tidak hanya meninggalkan jejak berupa dampak bencana, tetapi juga pelajaran berharga tentang bencana banjir di kawasan karst serta dinamikan bentuklahan yang menyertainya. Salah satu kawasan yang terdampak parah siklon tersebut adalah Luweng Belimbing yang terletak di Desa Pacarejo, Kecamatan Semanu, Kabupaten Gunungkidul. Penelitian ini bertujuan untuk menganalisis dinamika Luweng Belimbing pasca Siklon Tropis Cempaka. Analisis dinamika dilakukan dengan menganalisis perubahan luas luweng berdasarkan kajian sebelumnya menggunakan hasil pencitraan pesawat tanpa awak, survei lapangan dan wawancara dengan masyarakat sekitar Luweng Belimbing. Hasil analisis menunjukkan bahwa dinamika dapat dibagi menjadi lima tahapan yang saling berurutan.Kata Kunci: Siklon Tropis Cempaka, Dinamika Bentuklahan, Karst, Banjir, Luweng BelimbingTropical cyclones Cempaka that occurred in 2017 not only left the impact of disasters but also valuable lessons about flooding in the karst region and the accompanying landform dynamics. One of the areas badly affected by the cyclone is Belimbing Doline located in Pacarejo Village, Semanu District, Gunungkidul Regency. This research aims to analyze the dynamics of Belimbing Doline after Tropical Cyclone Cempaka. Dynamics analysis is done by analyzing changes in doline area based on previous studies using drone imaging results, field surveys and interviews with communities around Belimbing Doline. The analysis shows that the dynamics can be divided into five sequential stages, Keywords: Tropical Cyclone Cempaka, Landform Dynamic, Karst, Flood, Belimbing Doline

Abstract

Pemahaman tentang sistem hidrogeologi dan wilayah tangkapan air dari sebuah mata air sangatlah penting. Hal ini untuk membantu pengelolaan yang menjaga kelestariannya. Mataair Beton merupakan salah satu mataair yang memiliki peranan yang sangat penting di wilayah Ponjong, Kabupaten Gunungkidul. Suplai air dari mataair ini digunakan untuk memenuhi kebutuhan air bersih, irigasi persawahan dan perikanan. Penelitian ini bertujuan untuk mengetahui konektivitas dan karakterisasi lorong di sistem hidrogeologi Mataair Beton. Metode yang digunakan adalah tracer test dengan menggunakan fluorescent dyes. Hasil analisis menunjukkan bahwa Ponor Seropan memiliki konektivitas dengan Mataair Beton, dan memiliki karakteristik lorong berupa single conduit. Perkembangan lorong yang lanjut menunjukkan bahwa sistem hidrogeologi di lokasi kajian sangat dipengaruhi oleh imbuhan airtanah dari sistem alogenik yang berhulu di wilayah non-karst dan memiliki kerentanan terhadap pencemaran airtanah yang tinggi.Kata Kunci: Karst, Sungai Alogenik, Kawasan Karst Gunung Sewu, Uji Perunutan, Mataair BetonAn understanding of the hydrogeological system and catchment area of spring is very important. This is to help manage that maintains its sustainability. Beton Resurgence is one of the springs that have a very important role in the Ponjong area, Gunungkidul Regency. Water supply from the spring is used to supply clean water, irrigated rice fields, and fisheries. This study aims to determine the connectivity and characterization of Passage in the Beton hydrogeological system. The method used is a tracer test using fluorescent dyes. The results of the analysis of breaktrough curve indicate that Seropan Sinking Stream has connectivity with Beton resurgence, and has passage characteristics in the form of a single conduit. The further development of the passage shows that the hydrogeological system is strongly influenced by groundwater recharge originating from an allogenic system that originates in non-karst areas and has a high groundwater vulnerability to pollution. Keywords: Karst, Allogenic River, Gunungsewu Karst Area, Tracer Test, Beton Resurgence
