Abstract

The nitrate concentrations in shallow groundwater of the Yogyakarta City and its surroundings has increased to about twenty times in the period 1985-2018. The objective of this study was to analyse the distribution of nitrate concentrations in water well around the Code River, Yogyakarta. Flownets mapping was performed to find out the distribution and direction of potential groundwater pollution. Nitrate concentration was analysed by taking 18 groundwater samples scattered in the upstream, midstream and downstream areas of the Code River. The results of this study indicate that nitrate concentrations in the water well of upstream and downstream areas could still be used as a source of drinking water and recreation-irrigation-livestock. Meanwhile, the nitrate concentration in water well of the midstream area of the Code River, Yogyakarta City, mostly (80% of the sample) did not meet all classes of water quality standards. Human activities in the densely populated settlements were the main factors that influence nitrate pollution. Furthermore, groundwater flow in the study area leads from north to south and towards the Code River. This condition indicates that the nitrate concentrations in  the groundwater can be a source of a pollutant for the Code River.

Abstract

Considered as a trigger of climate change, greenhouse gas (GHG) is a global environmental issue. The City of Surakarta in Indonesia consists mainly of urban areas with high intensities of anthropogenic fossil energy consumption and, potentially, GHG emission. It is topographically a basin area and most likely prompts a Thermal Inversion, creating a risk of accumulation and entrapment of air pollutants or GHGs at low altitudes. Vegetation has been reported to mitigate the rate of increase in emissions because it acts as a natural carbon sink. This study aimed to mitigate the GHG emissions from energy consumption in Surakarta and formulate recommendations for control. It commenced with calculating the emission factors based on the IPCC formula and determining the key categories using the Level Assessment approach. It also involved computing the vegetation density according to the NDVI values of the interpretation of Sentinel 2A imagery. The estimation results showed that in 2018, the emission loads from the energy consumption in Surakarta reached 1,217,385.05 (tons of CO2e). The key categories of these emissions were electricity consumption, transportation on highways, and the domestic sector, with transportation on highways being the top priority. These loads have exceeded the local carrying capacity because they create an imbalance between emission and natural GHG sequestration by vegetations.

Abstract

The sand dune ecosystem phenomenon in the research area has unique and interesting characters. It is  identified that there is an  increase in the construction of the environment in the use of sand dune ecosystem which influence the groundwater quality. Such phenomenon is the manifestation of the existence of spatial dynamics influencing the groundwater degradation vulnerability. This research is aimed at 1) predicting the level of groundwater quality degradation vulnerability based on the sand dune ecosystem spatial dynamics; 2) developing an environmental management model to continuously maintain the availability of groundwater. The research employed survey research and inductive mapping. The aspect of the study included an environmental study with hydromorphological and hydrogeological approach. Analysis and evaluation were based on the multiplication of weight and rate, and were done on landscape units resulting from the map overlay. The research result  indicates  that there are 4 (four) classes of groundwater degradation vulnerability out of the 5 (five) classes of vulnerability determined beforehand. Groundwater degradation vulnerability classes III and IV indicate  problems of disturbances in the groundwater supply system and domestic and agricultural waste pollution. In order to overcome the disturbances in the groundwater supply system, water infiltration well should be constructed, communal domestic water processing should be encouraged, and in order to reduce pollution from the use of agricultural fertilizers, the fertilizers should be blended with clay.

Abstract

Batujai Reservoir locates in Batujai Village, Praya Barat, Central Lombok, West Nusa Tenggara. It is the primary source of irrigation water supply for agriculture in Central Lombok District with an area of around 3,235 ha. The problem is the bloom of water hyacinth weed (Eichhornia crassipes), which can cause reservoir water loss through evapotranspiration, affecting the amount of water reservoir available for the dry season. The objective was to identify the area of cover and estimate water loss through water hyacinth evapotranspiration for the period 2013 – 2017. This study used a descriptive method by analysis of secondary data which were meteorological data and landsat-8 satellite imagery. Evapotranspiration analyzes use CROPWAT 8.0, monitoring water hyacinth cover using landsat–8 satellite imagery processed using ENVI 5.3 and ArcGIS 10.4 software. The results show that the spatial distribution of water hyacinth can be detected and mapped accurately with an overall classification accuracy of 84.11% – 97.04% using Landsat 8 data, with a kappa coefficient of 0.80 – 0.96. The area of water hyacinth cover ranges from 38,400 m2 – 2,158,500 m2, with a cover area of more than 20%, causing water loss above 8,000 m3 day-1, which occurred in April 2013, April 2015, April 2016, February 2015, May 2014, May 2016 and July 2016, in those months it was seen that the amount of water loss was greater. Therefore, it is needed to suppress the growth of water hyacinth, in maintaining reservoir water storage capacity to support a systems of sustainable agriculture.

Abstract

The electroplating industry produces liquid waste containing a small number of heavy metals but is toxic. Wastewater containing chromium (Cr) absorbed into the soil will affect soil fertility. Waste management is needed so that the abiotic and biotic environment is not poisoned by Cr. Bioremediation using bacterial and fungal microbes are applicable to reduce Cr levels in electroplating liquid waste. The purpose of this research was to investigate the reduction level of Cr in electroplating liquid waste through bioremediation using Bacillus subtilis and Saccharomyces cerevisiae. Laboratory experiments were conducted using variations in microbial concentrations (102.5 cells ml-1 and 105 cells ml-1), variations in microbial types (Bacillus subtilis bacteria, Saccharomyces cerevisiae fungi, and mixtures of both microbes), and variations in incubation time (6, 12, and 24 hours). The initial Cr concentration and the results of the bioremediation process were determined by measuring the absorbance and the Cr levels using Atomic Absorption Spectrophotometry (AAS). Based on experiments, the use of Bacillus subtilis 102.5 cells ml-1 with a 24-hour incubation time reach the highest percentage reduction in Cr (88.96%), followed by 12-hours incubation time (84.73%), and 6-hours incubation time (79.21%). Furthermore, the use of a microbial mixture of Bacillus subtilis and Saccharomyces cerevisiae 102.5 cells ml-1 with 6-hours, 12-hours and 24-hours incubation time was able to reduce the levels of Cr respectively by 77.46%; 80.18% and 83.04%. Next, Saccharomyces cerevisiae 105 cells ml-1 with 6-hours, 12-hours, and 24-hours incubation time was able to reduce levels of Cr in a row by 50.17%; 52.35% and 55.63%. The results of this study indicate that the bioremediation process using the microbial Bacillus subtilis and Saccharomyces cerevisiae is proven to reduce the levels of Cr in the electroplating industry wastewater. The highest reduction results were achieved on the use of 24-hour incubation time and the use of Bacillus subtilis with a concentration of 102.5 cells ml-1 at 88.96%.
