TL;DR: In this article, the authors determined the level of groundwater vulnerability to pollution by using the SINTACS method and analyzed the dominant factors that influence it, and found that the variation of the groundwater vulnerability index values in the study area ranged from 182.8 to 200.3.
Abstract: As one of the districts in Bantul Regency which borders directly with the City of Yogyakarta, the District of Banguntapan has the potential to be an area affected by city development. This is what drives population growth in this district, so that the waste it generates also increases. The purpose of this study is to determine the level of groundwater vulnerability to pollution by using the SINTACS method and analyzing the dominant factors that influence it. Calculation and analysis results show that the variation of groundwater vulnerability index values in the study area ranged from 182.8 to 200.3, with 10 locations classified as high vulnerability and 2 locations classified as rather high vulnerability. Because it is located in a similar geological condition, namely the Aquifer Unit of Merapi Volcanic Fluvio Plain where most of the constituent material of this aquifer is sand and a little clay as inserts, the difference in groundwater vulnerability to pollution in the study area is only determined by the difference in groundwater depth.

TL;DR: In this article, a study was conducted to assess groundwater vulnerability in the study area for pollution using the GOD method and conduct a study of three groundwater vulnerability assessments, to determine the most appropriate assessment to be applied in the area.
Abstract: Groundwater vulnerability to pollution refers to the ease with which pollutants reach groundwater, in other words indicating the level of ease of an area to experience pollution. At present, the theme is one of the themes that attracts many researchers because pollution is more frequent in an area. The purpose of this study is to assess groundwater vulnerability in the study area for pollution using the GOD method and conduct a study of 3 groundwater vulnerability assessments, to determine the most appropriate assessment to be applied in the study area. The method used to determine groundwater vulnerability to pollution is GOD, which uses three parameters to assess the vulnerability of groundwater, namely aquifer type, rock type above aquifer and groundwater level. Furthermore, the results of the vulnerability assessment using the GOD method are compared with the vulnerability assessment according to the SINTACS and DRASTIC methods that have been carried out before in this area. The results showed that the variation of groundwater vulnerability index values in the study area according to the GOD method was from 0.35 to 0.63. Locations that are classified as medium vulnerability are generally located in the limestone Sentolo Formation, while locations that are classified as high vulnerability class are located in the volcanic rock of Yogyakarta Formation. Noting the results of determining groundwater vulnerability from the three methods, it can be said that the three methods are suitable for assessing groundwater vulnerability in the study area. However, looking at the distribution pattern of the level of pollution, the DRASTIC method can provide more detailed results related to the level of vulnerability.

TL;DR: In this paper, an integrated water resources management model in the study area was formulated and the model obtained was then simulated using the Powersim 2.5c computer program, which showed that the combination of these two methods will slow down the time the safe yield will be exceeded, from 2039 to 2049.
Abstract: Banguntapan District in Bantul Regency is one of the peri-urban areas in the Special Region of Yogyakarta. The peri-urban area is an area located between the urban (Jogja City) and the rural (Bantul Regency). As a result of this strategic location, the development of this district is very rapidly marked by the growth of settlements, which in turn further requires water for housing purposes.The purpose of this research is to formulate an integrated water resources management model in the study area. To achieve this goal dynamic modeling is used. The model obtained was then simulated using the Powersim 2.5c computer program. Management efforts that can be carried out in this district are reducing groundwater use through saving water use and increasing water use from local water companies. Simulation results show that the combination of these two methods will slow down the time the safe yield will be exceeded, from 2039 to 2049.

TL;DR: In this paper, the authors evaluated the use of groundwater in the study area in relation to its vulnerability to sea water intrusion and the depth of its interface, and the results of this water usage calculation were then linked to the criteria for groundwater vulnerability to water intrusion.
Abstract: Besides being able to cause land subsidence, excessive groundwater use in coastal areas can also cause to sea water intrusion. The purpose of this study is to evaluate the use of groundwater in the study area in relation to its vulnerability to sea water intrusion. Because groundwater in the study area is used for domestic, industry and livestock purposes, the water use that is taken into account is the use of water for the three sectors. The amount of water used for domestic purposes is calculated based on the population and the amount of water needed of each person per day. The amount of water use for industry is calculated based on the number of industrial employees and water usage of each employee per day. Water use for livestock is calculated based on the number of livestock and water use of each livestock per day. The results of this water usage calculation are then linked to the criteria for groundwater vulnerability to sea water intrusion and the depth of the interface. Observing the relationship between groundwater usage and the vulnerability of groundwater to sea water intrusion and the depth of its interface, Tegal Kamulyan, Cilacap and Sidakaya villages, all of which are located in South Cilacap District, need attention. The three village are classified as moderate vulnerability to sea water intrusion and shallow interface depth, but their water usage is quite high. For this reason, it is necessary to make efforts to find other water sources for domestic, industry and livestock requirement other than groundwater.

TL;DR: In this paper, a static groundwater potential calculation and the water needs are carried out to determine the groundwater potency and domestic needs of the population in Banguntapan District in Bantul Regency.
Abstract: Banguntapan District in Bantul Regency is one of the districts bordering the City of Yogyakarta. Because of its strategic location, the development of this district is very rapidly marked by population and settlement growth. As a result, the demand for facilities and infrastructure has also increased including the need for groundwater for domestic water sources. The purpose of this study is to determine the groundwater potency and domestic needs of the population. The study of domestic water demand is carried out to find out the current water needs and the level of criticality. For this reason a static groundwater potential calculation and the water needs are carried out. Calculation and analysis results show that groundwater potency in unconfined aquifers in the study area is 279, 004, 000 m3 /year, with safe yield of groundwater extraction are 13, 109, 292 m3 /year. Although groundwater extraction for domestic demand which amounted to 6, 392, 874 m3 /year is still smaller than the safe yield, according to the calculation of the criticality index the water is almost classified in the critically approaching criteria.

TL;DR: In this paper , the authors have made an attempt to know the behaviour of groundwater levels during the same period as that of land use land cover, and the results indicate a 74 % depletion in groundwater levels with an average annual depletion of 21 %.
Abstract: Abstract Greater NOIDA evolved from 1991 with 101 villages to 2020 with 293 villages. This is an ideal case of rural to urban transformation in the immediate past. This transformation led to a decrease in recharging natural surfaces and an increase in impermeable surfaces. Along with the reduction in recharge areas, an increase in population has necessitated more and more extraction of groundwater resulting in an imbalance of water extraction and recharge. The result is depletion of groundwater levels in this area. The area is part of the wide Indo-Gangetic alluvium with sand, silt and clay layers resting on quartzite’s of Delhi Super Group. Geomorphological map prepared using digital elevation models of the area shows older and younger alluvial plains and active flood plains of the river Hindan. Time series analysis of key land use land cover classes shows that recharge areas were reduced from 77 % to 30 % from 2005 to 2019 and impervious surfaces have increased from 19 % to 65 % for the same period. Aquifers of the area are both phreatic and semi-confined. The aquifer parameters estimated through step drawdown test and long duration aquifer performance test indicates that the average coefficient of transmissivity of the area is 1752 m2/day and the average coefficient of storage is 4.84 x 10-4. Discharge of the wells shows a yield of 8 to 16 lps for a drawdown of 3 to 6 m. An attempt has been made to know the behaviour of groundwater levels during the same period as that of land use land cover. The results indicate a 74 % depletion in groundwater levels with an average annual depletion of 21 %. An interrelationship between urban growth and groundwater levels has been established in this study. This analysis indicates that as agriculture declined water levels also depleted and have a positive correlation of 0.852. On the contrary, as the built-up increased water level has depleted hence have a negative relationship with a correlation coefficient of -0.851. To make it a sustainable resource, these overexploited aquifers need careful participatory management by communities, Scientists, and policymakers.

TL;DR: In this article, the authors analyzed the increase in rainfall, air temperature, potential evapotranspiration and actual evapOTranspiration in the Bengkulu watershed over a period of 5 years.
Abstract: Global climate change that occurred in this century can affect the pattern of rain and increase in temperature on earth. This study aims to determine and analyze the increase in rainfall, air temperature, potential evapotranspiration and actual evapotranspiration in the Bengkulu watershed. For this reason, the regional rainfall is calculated using the Thiessen Polygon, the mean air temperature of the watershed based on the median elevation, potential evapotranspiration using the Thornthwaite Method and actual evapotranspiration using the basis of the difference in rainfall to potential evapotranspiration. The results showed that every year there was an increase in rainfall, air temperature, potential evapotranspiration and actual evapotranspiration in the Bengkulu Watershed. In the 2009-2013 period, the average annual rainfall of 3,581 mm increased to 3,641 mm in the 2014-2018 period. For air temperature, the average monthly air temperature in the Bengkulu Watershed for the 2009-2013 period was 25.8°C, while the air temperature in the 2014-2018 period was 26.1°C. This means that in a period of 5 years there is an increase in temperature of 0.3°C. Furthermore, due to the increase in air temperature, there was an increase in the average monthly potential evapotranspiration from the 2009-2013 period to the 2014-2018 period, namely from 1,493 mm to 1,537 mm, while for actual evapotranspiration there was an increase from 1,486 mm to 1,518 mm.

TL;DR: In this article , an intrinsic groundwater vulnerability assessment to anthropogenic contamination in Kasihan, Yogyakarta, Indonesia was conducted based on Groundwater confinement, Overlying materials and Depth to groundwater table (GOD) method.
Abstract: Groundwater contamination is a ubiquitous problem, especially in developing countries such as Indonesia. Groundwater vulnerability assessment is an effective tool that provides information about the status of groundwater and potential contaminants. This approach helps in groundwater conservation and management. This study conducted an intrinsic groundwater vulnerability assessment to anthropogenic contamination in Kasihan, Yogyakarta, Indonesia. This research delineated the spatial distribution of physicochemical properties of groundwater and analysed land-use patterns. This study was conducted based on Groundwater confinement, Overlying materials and Depth to groundwater table (GOD) method. The GOD method was applied to assess the intrinsic properties of the geology and hydrogeology of the study area. Secondary land use data were analysed using GIS software to determine major anthropogenic activities in the research area. Land use and cover analysis of the study area indicated a rapid development including settlement, agricultural and industrial facilities. Groundwater vulnerability assessment showed medium to high classes. These findings suggest a high probability of contamination at present and in the future. Thus, future researchers should assess the groundwater quality of Kasihan based on specific vulnerability using groundwater flow and mass transport modelling because the investigated area is highly susceptible to pollutants.
