Abstract Groundwater is the main source of water supply in Sleman Regency. Although quantity not an issue, quality groundwater should be understood to ensure sustainability supply. A previous study shows increase manganese (Mn) and nitrate (NO 3 ) concentration groundwater, yet distribution unknown. Therefore, this aims develop a map spatial pattern analyze potential Regency Yogyakarta Province...

Landfill activities can produce leachate water that be infiltrated into the soil so it pollute surrounding well water.. This study aims to map distribution of quality shallow groundwater around TPA. Sampling owned by residents is 100-700 meters from TPA and 2 sample points Sukosari The parameters analyzed include, pH, BOD, COD. standard for used class I Government Regulation No.82 2001, while M...

Accurate spatial distribution information of rainfall is essential to rainfall-induced hazard predictions and statistical interpolation methods may serve as a useful tool produce detailed from coarse data sources. Although numerous comparison studies about different have been conducted on irregular rain-gauge networks, there need perform such work the increasingly available gridded data. Carrie...

Objective: This study aimed to map the spatiotemporal hotspots of tuberculosis (TB) prevalence distribution in Western Region Java Island. Material and Methods: To investigate pattern TB prevalence, we standardized by year, with percentile being clustered natural Jenks breaks optimization. estimate continuous geographical within each district, performed inverse distance weighting (IDW) methods ...

Assessment of groundwater quality is utmost importance to ensure sustainable use water. Since the availability water, irrespective quantity and quality, varies from area in Thanjavur taluk. The present paper attempts determine spatial distribution parameters identify locations with best for drinking irrigation study using GIS WQI. Using IDW interpolation methods ArcGIS 10.8, maps physical param...

Rainfall observation data from each rain station in an area is so important to measure the intensity of rainfall that region. The number stations are not ideal will affect process acquiring which primary required for regional mapping. This study uses manual technique and analysis satellite precipitation as alternative aid mapping annual with Isohyet method areas constrained by a shortage like N...

In the present study, a new approach by coupling interpolation method with computation-based technique (data-mining algorithms and an optimization algorithm) is introduced for modeling removal of Reactive Orange 7 (RO7) dye from synthetic wastewater. To this end, four significant factors like pH, electrolyte concentration, current density, electrolysis time are considered as input variables. Th...

Widespread use of GPS systems in agricultural vehicle allows farmers to collect elevation data repeatedly to develop field-level DEM. Accuracy of these DEMs can be improved by understanding how errors are introduced from sampling procedures. In this research, a 120 m by120 m test field was modeled using a 10-mgrid USGS DEM of Winneshiek County, Iowa. Multiple sets of vehicle-based GPS elevation...

In this paper, we propose a novel air-conditioning system that will be effective for wide public space such as a concourse of railway station, exhibition hall or museum. In these spaces, conventional air-conditioners are not enough, since the air-conditioner sends a wind to also empty area and where the temperature is already sufficient. Generally, it is difficult to ventilate effectively to th...

We describe a gridded daily meteorology dataset consisting of precipitation, minimum and maximum temperature over Java Island, Indonesia at 0.125°×0.125° (~14 km) resolution spanning 30 years from 1985-2014. Importantly, this data set represents a marked improvement from existing gridded data sets over Java with higher spatial resolution, derived exclusively from ground-based observations unlik...
