Cekungan Airtanah Yogyakarta-Sleman memiliki peranan penting dalam menyediakan sumber air bagi masyarakat Kabupaten Sleman, Kota Yogyakarta, dan Kabupaten Bantul. Jika tidak dikelola dengan baik, maka pemanfaatan airtanah secara berlebihan dapat menurunkan kualitas dan kuantitas airtanah. Penelitian ini bertujuan mengetahui tingkat pemanfaatan airtanah di kawasan Cekungan Airtanah Yogyakarta-Sleman. Metode yang digunakan adalah perhitungan airtanah dinamis dan pemanfaatan air menurut Standar Nasional Indonesia (SNI) nomor 19-6728.1-2002. Hasil penelitian menunjukkan bahwa trend total pemanfaatan airtanah dari tahun 2013 ke tahun 2018 mengalami peningkatan di Kabupaten Sleman, Kota Yogyakarta, dan Kabupaten Bantul. Namun jika dilihat dari tingkat pemanfaatan airtanah, Kabupaten Sleman, Kota Yogyakarta, dan Kabupaten Bantul didominasi tingat pemanfaatan rendah, sedangkan tingkat pemanfaaan sangat tinggi di Kabupaten Sleman terdapat di Kecamatan Godean dan Gamping. Tingkat pemanfaatan sangat tinggi di Kota Yogyakarta terdapat di Kecamatan Umbulharjo. Sedangkan tingkat pemanfaatan sangat tinggi di Kabupaten Bantul terdapat di Kecamatan Imogiri. Dengan demikian dapat disimpulkan bahwa tingkat pemanfaatan airtanah di kawasan Cekungan Airtanah Yogyakarta-Sleman cukup beragam, didominasi kategori rendah namun terdapat beberapa kecamatan dalam kategori sangat tinggi, sehingga zona pemanfaatan airtanah di CAT Yogyakarta-Sleman masih memerlukan pengendalian, agar dapat lestari dan dimanfaatkan dalam jangka panjang.

Publisher : Brawijaya University

The groundwater quality in Wates coastal area is generally a good category but there are high salinity values at some locations. The chemical quality of groundwater from place to place is different. The difference of water quality is a major problem in the study area. A total of 27 groundwater samples were collected in August, 2017. Geochemical signatures of groundwater were used to analyze the major ionic concentrations in the groundwater, to identify the dominant hydrogeochemical processes, and to determine the relationship between groundwater flow and spatial distribution of water types. Hierarchical Cluster analysis and Schoeller diagram, Gibbs plots, Scatter diagrams, and Piper Trilinear diagram were employed to evaluate the hydrogeochemical evolution of groundwater. In Schoeller diagrams, the relative tendency of ions in meq/L shows Na+ > Mg2+> Ca2+> K+ and HCO3- >Cl- > SO42-trends, typically in saline water. Gibbs diagram reveals that the groundwater chemistry is mainly controlled by rock weathering with secondary contribution from evaporation source. Based on the results of Hierarchical Cluster analysis and Piper diagram, dominant hydrogeochemical facies in the study area are Ca-HCO3, Na-Cl, and Ca-Na-HCO3 types. Ca-HCO3 facies are almost throughout the study area and the evolution of groundwater was mainly controlled by the silicate weathering process. Na-Cl water types are grouping in the study area influenced by cation exchange and evaporation processes, while Ca-Na-HCO3 types are locally grouping with silicate weathering and cation exchange processes. The geology implies that common silicate minerals are found everywhere in the study area. In fact, the distributions of groundwater facies are related to the local geology, which may result in different hydrochemical processes. In addition, lithology is very influential on the existence of groundwater in the study area

In 1997, groundwater pollution was caused by a diesel leak at the Yogyakarta City Railway Station. People in the south of the railway station discovered the presence of diesel in dug wells in 2001. The existing diesel is still found in dug wells even though the pollutant source had been removed. The current source of pollution comes from diesel residues trapped in the unsaturated zone. Understanding the distribution and concentration of diesel in the unsaturated zone is the goal of this study. In this study, diesel concentration was measured based on Total Organic Carbon (TOC) levels. The research was conducted through shallow core and deep core drillings. Shallow core drilling was done at 14 points with a depth of 50 cm, and deep core drilling was done at nine drilling points with a depth of 15-17 m. 14 shallow core drilling samples were taken from a depth of 30 and 50 cm and nine deep core drilling samples were taken from a depth of 4-5 m and 10-11 m. The lithology logs in both drills were tested for diesel odour and TOC levels using the Soli TOC tool. Based on the test results, the smell of diesel was found at a depth of 10 to 15 m. TOC levels in the unsaturated zone ranged from 340 to 90,870 mg/L. TOC levels >30,000 mg/L were dominant at shallow depths even though they did not smell like diesel. At a location close to the source of the diesel tank leak at a depth of 4-5 m, the measured TOC level was 30,100 mg/L. The results showed that there were zones of high TOC levels associated with diesel odour layers. The zones existed because of the infiltration and percolation processes that had carried surface water and diesel pollutants and eventually moved horizontally following groundwater flow.

The number of unregistered artesian wells increases every year in the northern slopes of Bromo Volcano, Pasuruan. Artesian wells are used for domestic needs and agricultural irrigation but are not followed by environmentally sound groundwater use. The purpose of this study is to assess the potential for groundwater, groundwater use, wasted groundwater, and recommendations for groundwater management. The groundwater potential was obtained by measuring the depth of the groundwater table, piezometric surface of artesian wells, and geoelectrical data. Water uses were obtained from calculations based on the Indonesian National Standard. The amount of wasted groundwater was obtained by comparing the groundwater potentials, groundwater uses, and groundwater discharges from unregistered artesian wells. Water transfer was assessed by selecting unregistered artesian wells with discharges able to fulfill the water demands of each village. Groundwater in the Sub-Districts of Gondang Wetan and Winongan has high potential consisting of 1 unconfined aquifer group and two confined aquifer groups. Gondang Wetan and Winongan Sub-Districts are characterized as wasting groundwater potential through unregistered artesian wells. The discharge flow of unregistered artesian wells exceeds the water needs (>100%) in Winongan and Gondang Wetan Sub-Districts. Groundwater can be managed by water transfer, closure of artesian wells, and regulation of artesian wells use. Water can be transferred to areas not covered by Artesian wells in 20 villages. The number of artesian wells used for water transfer is 20 with a discharge of 5-20 liters/s.

Theoretically environmental isotopic compositions ofprecipitation decrease with increasing altitude. Linear regression analysis was applied to environmental isotopic compositions (δ18O, δ2H) data on 15 precipitation samples collected along an altitudinal 126 to 1260 m.asl from November 2011 to February 2012 to determine the local meteoric water line for southern slope of mount Merapi. Merapi meteoric water line (MMWL) is an equation that describes the relationship between isotopic compositions of precipitation with altitude. This study was completed as part of a larger research of the groundwater dynamics studies using natural isotopes for southern slope of mount Merapi.Isotopic compositions of precipitation samples were measured using Liquid-Water Stable Isotope Analyzer LGR DLT-100 at the Center for the Application of Isotopes & Radiation Technology Laboratory, National Nuclear Energy Agency (BATAN), Jakarta. Regression results for the precipitation samples for southern slope of mount Merapi yielded a MMWL defined by the equation δ2H=8.332 δ18O+15.068(r2 =0,998); the change of isotopic compositions in precipitation with altitude of about -1.2%d100m for deuterium and -0. 1 %dl 00m for oxygen-18.This equation will be useful as reference for hydrological dynamics studies on the southern slope of mount Merapi that use isotopes of 2H and 18O to trace sources of ground-water recharge, to evaluate mixing of sea-water and groundwater, to analyze groundwater-mineral exchange, and to analyze many other groundwater contamination problems.Keywords: precipitation, isotope ratio, isotopic composition, m.asl, MML .

Pucang Village was consisted of eruption materials of Merapi Volcano. The relatively high coefficient of permeability of the materials consisting this area caused rainwater to directly infiltrate into the ground. Evaluation of engineering geological conditions was conducted for construction of a detention pond in this area, which had limited water supply for daily activities. The evaluation was conducted on results of a 1:10.000 scale of engineering geological mapping and analyses of 1:10.000 scale of geological disaster maps produced by previous researchers. The engineering geological mapping involved mapping of morphological condition and active geomorphic process, lithological condition, existence of geological structure, and water source location. The evaluation results showed that the proposed location met the land suitability criteria for detention pond construction based on the morphological condition and active geomorphic process, existence of geological structure, and water source location, but did not meet those based on the lithological and vulnerability to Merapi Volcano eruption disaster. Construction of impermeable layer to prevent water seepage into the ground and periodic removal of sediment in the base of the detention pond were suggested to be carried out to keep the detention pond functioning properly.
