Abstract

Groundwater balance occurs in the presence of recharge and discharge. The process of entering the water in soil takes place with an infiltration-percolation to aquifers. The groundwater recharge area is identified by lithology, land use, slope, rainfall, land, and landform. Kajor Kulon Hamlet, Selopamioro Village, Imogiri Sub-district, Bantul Regency, Special Region of Yogyakarta becomes an area with hilly morphology, active fault areas, and including drought-prone regions. Change of the land function in hilly areas by making settlements and un-irrigation field for farming may cause decreased ability as a recharge area. Research aim sare to assessing, determining, and analyzing the conditions of the establishment in the research area. The variables used include land use, the slope of the land, rainfall, and soil texture as thematic maps to analysis its land ability. Data collection methods are measurement, inquiry, and mapping. Furthermore, the method of analysis is based on the Geographic Information Systems (GIS) with scoring-weighted overlay method. The results showed the classification of the between low, medium, and high. The medium class is currently occupying 67% of the area in the research area with an area of 719,916.03 m2. The distribution of each class is expressed through the groundwater recharge area map. The GIS is very efficient and effective in facilitating groundwater recharge area analysis.Keywords: GIS, Groundwater, Overlay, Potential, Recharge Area, SelopamioroDOI: http://dx.doi.org/10.7454/jglitrop.v4i2.89

Abstract

Landslide hazards can be caused by several factors such as lithology, land cover, rainfall, slope, curvature, aspect, distance from river and road. In this study, a landslide susceptibility mapping was carried out using a Geographical Information System (GIS) in Kabandungan District and Salak Geothermal Field, West Java. The data used consisted of an inventory of points and landslide areas totalling 247 using a visual collection of Google Earth imagery. The Weight of Evidence (WoE) model is used to select parameters that cause landslides and to produce landslide vulnerability maps. The results of modeling indicate a positive relationship between selective factors for the occurrence of landslides, with Area Under Curve value of 0.89359; 0.76395; 0.75277; 0.73280 and 0.69093 respectively. Landslide susceptibility maps are made by adding up the WoE values for all the most influential parameters. Higher total WoE value is indicating a higher probability of landslide. Landslide susceptibility maps can be used as an effort to prevent potential hazards or mitigate landslides. In addition, this map can also be used furtherly for spatial planning and engineering activities.Keywords: landslide susceptibility, causative factors, Kabandungan, Salak Geothermal Field, Weight of Evidence, Area Under CurveDOI: http://dx.doi.org/10.7454/jglitrop.v4i2.75

Abstract

This study discusses how people in Kuningan Regency divided into indigenous and immigrant communities interpret human relations with nature as well as changes in the context of the natural environment identified through the configuration of the components of the settlements. The observed natural environments include water, land, forest, and mountains, while the settlement components include houses, village halls, mosques, cemeteries, and rice fields. The data used in this study is qualitative data from various literature, maps, observations, and in-depth interviews. The method used in this study is the method of interpretation to reveal the meaning behind the spatial pattern of settlement as a unity of signs. The results reveal that the influence of water and land was more dominant in nature-depended traditional settlement and transition settlement. Meanwhile, forests and mountains did not have a major impact on the spatial patterns of all three categories of settlements.Keywords: Spatial Pattern, Sundanese Philosophy, Semiotics, Settlement, Cultural Geography.

Abstract

The study investigated changes in channel planforms of River Kaduna. Topographic maps were complimented with Mosaic of SPOT 5 satellite and Sentinel-2 images. Results showed that except for sinuosity index and channel length, channel width, braiding and channel migration exhibited considerable changes. These changes were evident in reduced velocity and stream energy, the type of sediment being transported, the silt materials being transported in suspension and the coarse sand and gravels being moved by lift and drag processes which are easily deposited, thus causing the channel to contract and braid. Channel migration occurred as gradual bend shifts leaving no evidence of lateral abrasion. Similarly, channel length did not change significantly to affect the sinuosity index. The result further revealed there was little lateral abrasion and the channel are relatively stable, implying that the materials being transported and deposited must have originated from the watershed. Anthropogenic factors such as urbanization, deforestation and agriculture activities contributed significantly to the observed channel alteration. There is a need to encourage mining gravel and sand from braided channels to provide sinks for sediments that otherwise would be deposited downstream. Afforesting the catchment area is required to create canopies to exposed surface and reduce sediment supplies.Keywords: braiding, channel migration, channel planforms, channel width, remote sensingDOI: http://dx.doi.org/10.7454/jglitrop.v4i2.85

Abstract

The aim of the present research is to examine the effectiveness of rational method widely used in calculating water availability for spatial planning in Indonesia. The rational method is developed mainly for estimating the characteristics of drainage infrastructure instead of estimating water availability. The effectiveness of rational method and Soil-Conservation Service Curve Number (SCS-CN) method are compared by testing their performance in estimating water availability in the Upper Cisadane river basin in West Java, Indonesia. The results shows that calibrated SCS-CN model performs better than Rational model with R2 and NSE of 0,62 and 0,37. Result of model validation yields R2 = 0,73 and NSE = 0,52. The result suggests that SCS-CN performs better than the rational model in simulating the character of water catchment area and is suitable for model of choice in water availability estimation.Keywords: Bogor City, Regional Spatial Planning, Water availability, Water Balance, Water Resource Carrying Capacity

Abstract

The increase in population and industrial growth has led to increased production of industrial and domestic waste which contain heavy metals in various forms. Therefore, affect the diversity and activities of soil microbes and subsequently affect environmental sustainability. This research aimed at assessing the distribution of heavy metals, soil enzymes, and evaluate the functional relationship if any. The study area was divided into two locations as contaminated and control; thus, each location one square kilometre was demarcated and divided into 25 small square (grid). A Sample was collected in each grid from 0 – 15 cm depth using point composite sampling technique. The properties investigated are heavy metals, enzymes, pH, and soil temperature. The results of the analyses were subjected to statistical analyses to undertake one-way analysis of variance, and a t-test of means at ???? value of <0.05, also correlation, and regression at a P<0.05 significant level. The results revealed that there is a gradual accumulation of all heavy metals and the concentration is higher in the contaminated than control locations. The soil is potentially polluted with Cd is clean from Cr, Fe, Mn, Zn, Pb, and Cu. High values of heavy metals were discovered in the dry season than the wet season due to rainfall which enhanced the dissolution, leaching, and runoff of heavy metals which is capable of removing the metals from the subsurface. High pH and temperature in the contaminated location influenced the toxicity and microbial activity respectively, this results in high enzymatic activity in the contaminated location. Favourable environmental conditions in the wet season led to the higher activity of the enzymes than the dry season. The finding also revealed that phosphatase and urease were negatively correlated with Cd and Ni. Inversely, dehydrogenase was negatively correlated with Ni and Zn. It was concluded that the determination of the heavy metals and enzymes reflects the microbial activities in soils and is considered as soil quality indicators.Keywords: soil enzymes, contamination, soil microbes, biological indicator, soil qualityDOI: http://dx.doi.org/10.7454/jglitrop.v4i2.81

Abstract

The accumulation of toxic heavy metals in excessive quantities has a detrimental effect on soil quality which interferes with key biochemical processes in soils. It is very imperative to explore soil microbial activities concerning to environmental conditions for sustainable soil management. The study aimed to assess the seasonal distribution of soil microbial biomass carbon (MBC), some heavy metals and pH, and their relationship in the soil ecosystem. Field investigation and laboratory analysis were the main methods adopted as sources of generating data and analyses. Ten soil samples were collected using composite sampling techniques on seasonal bases and then analyzed in the laboratory. The results were subjected to statistical analyses using t-test and the Analysis of Variance (ANOVA) at ????<0.05. Pearson’s correlation andregression analysis was analyzed to determine the relationship among the variable at P<0.05. The results show that locations with higher values of MBC corresponded with locations with high Cr, Cd, and Pb. High values of Cr, Cd, and Pb were observed in the dry season. On the other hand, in the wet season, rainfall enthused dilution, leaching, and runoff of Cr, Cd, and Pb and then removed from subsurface. High MBC in the wet season is due to favorable conditions for the microbial population and rapid mineralization due to high moisture and temperature than the dry season where there are low moisture and temperature. The analysis revealed that MBC was positively related to Cr, Pb, and was negatively related to Cd. However, the variation of MBC was explained by Cr, Cd, and Pb by 64% and 52% for dry and wet season respectively. It was concluded that the toxicity of heavy metals in soil depends on the pH level and therefore, determination of MBC, Cr, Cd, Pb, pH, and temperature of soil reflect the microbial activities in the soil and could be considered as soil quality indicators. Keywords: soil microbes, mineralization, organic matter, contamination, heavy metals, soilDOI: http://dx.doi.org/10.7454/jglitrop.v4i2.80

Abstract

Abstract. In urban areas where there are many centers of government, trade, education, and other activity, telecommunication device is widely used on publication, transactions or services, administration and promotion, while the internet needs of individuals are commonly used for communication, socialization, seeking information and entertainment. At this time, online games are not only played by using a personal computer but also the presence of a smartphone with its advanced technology that can be connected with the internet network is one of device for online gaming. Mobile gaming requires good latency to run smoothly and comfortably. The need for the telecommunications system uses frequency waves for signal propagation. However, signal propagation can be interrupted due to many factors that affect, for example, distance from BTS (Base Transceiver Station), building density, and terrain shape. This study investigated the relationship between signal quality, internet speed, and latency to the distance from BTS, building density, and shape of the terrain. The results showed that signal quality, internet speed, and good latency were found in areas where near BTS and had a low level of building density.Keywords: internet speed, latency, signal quality, spatial model
