Abstract

A hundred and thirty two (132) Oil spill Incidents that occurred in year 2015 based on the existing SPDC Oil Spill JIV Reports were studied using GIS. The JIV reports were downloaded and the requisite information was acquired and incorporated into ArcMap10.2 and they were analysed to produce different maps. Result shows that about 18,233.04bbl of Oil was spilled and an area of 1,718,091.88m2 was impacted in year 2015.Pipelines account for 65.15% (86) of the spills, followed by flowlines 14.39% (19), Wellheads 13.63% (18) while others account for the rest. Pipelines are the most sabotaged Production Facility with 73.63 %( 81) of the Sabotage that occurred followed by wellhead13.63 % (15) and, flowline 10 % (11) while other Production Facilities account for the rest. This Study also shows that JIV Reports to an extent are a good and convenient tool for characterising Oil spills and the JIV culture should be encouraged. This study should be carried out on all JIV so that they are put in a Digital Format where they can be easily queried to produce the necessary information as needed.

Abstract

This study aims to look at the conditions and characteristics of significant wave height and its relationship to wind velocity in the Makassar Strait in 2017. The data used in this study are bathymetry data from GEBCO with a resolution of 30 seconds, significant wave height data (Hs) with a resolution of 0.25 x 0.25 as well as wind velocity and direction with a resolution of 0.25 x 0.25 which are secondary data results from the European Center for Medium-Range Weather Forecasts (ECMWF) with a span of one year in 2017. The method used in this research is an analysis of the energy spectrum of significant wave height using Fast Fourier Transform. In addition, wind velocity and direction are processed by using GrADS software to see the visual conditions. Based on this study, it can be concluded that wind velocity is strongly associated with significant wave height values. This can be seen at each sample point in the Makassar Strait, where when the value of wind velocity is high, the value of significant wave height has the same conditions, and vice versa. The wind velocity value has a maximum value in the Makassar Strait during the east season with a value of more than 4.5 m/s. The highest energy spectrum occurs at point 3 in the Makassar Strait, which is 7303 m2 with a period of 6 months.

Abstract

Tidal swampland is one of sub optimal land that potential as a backup of fertile field in Java island. However, due to the global climate change, negatively impact the paddy production including the cropping time that shifted year by year. Therefore, the objective of this study was to develop a cropping calendar map of tidal swampland in three conditions, i.e. dry, normal, and wet years. This map was developed by analyzing the relationship between precipitation and tide overflow data. Also, primary data from field survey and farmer questionnaire were used for verification. The area was delineated by cropping calendar combined with administration, climate, tidal swampland, and rice field map.  Using this map, the cropping time in tidal swampland field can be potentially increased become twice a year. By proper cropping time, the paddy production in tidal swampland of South Kalimantan also potentially will increased directly.

Abstract

Soil erosion is a serious environmental problem that is associated with societal impacts including flooding, poor water quality, and loss of plant nutrient leading to low agricultural productivity. Soil erosion wears away the top soil and is controlled by the interaction between several factors including rainfall, steepness of slope, length of slope, vegetation cover, and land management practices. This study developed Geographic Information System (GIS) graphical model based on the Revised Universal Soil Loss Equation (RUSLE), to calculate soil loss in the Asokore Mampong Municipality of the Ashanti region, Ghana. The estimated soil loss was examined the spatial patterns of soil loss and intensity per areas, as an important method for proper planning of management measures. The graphical model was developed using the popular open source GIS software, QGIS, ensuring the availability of the model, automation for any specific area, and its execution to the general public. Data sources used include Digital Elevation Model (DEM) derived from ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer), soil properties data obtained from the Global Soil Grids, land cover data from the Global Land Cover by National Mapping Organization (GLCNMO), NDVI (normalized difference vegetation index) data from MODIS (MOD13Q1, 16 Day), and rainfall data from GPCC version 7 (Global Precipitation Climatology Centre). Our results show high levels of soil loss (in tons per hectare per year) in the Municipality, with the capability to spatially target mitigation measures leading to cost effective environmental management.

Abstract

Lake Matano and Towuti are two of 15 lake priorities in Indonesia. For preservation purposes, a routine water quality monitoring from satellite is needed. In this study, 11 scenes of Landsat 8 data were processed to produce chlorophyll-a concentration as an indicator of water quality condition on these two lakes. The result showed that water quality in Lake Matano and Towuti were in low cholorphyll-a condition with chlorophyll-a concentration ranged from 0.000– 2.298 mg/m3, 0.000-2.236 mg/m3, respectively. The accuracy of estimated Chlorophyll-a in these two lakes were affected by an inaccurate of atmospheric corrected data. To improve the accuracy, a more accurate atmospheric correction algorithm for Landsat 8 was still required.

Abstract

Indonesia is a country that vulnerable to land and forest fires danger. This is not out of the presence of peatland in Indonesia is quite wide, which are mostly located in Sumatara and Kalimantan. The nature of peatlands are capable to store water in large quantities, but the surface dries quickly and become flammable during the dry season. This research aims to perform mapping areas that vulnerable to land and forest fires danger based on the physical parameters. Based on the results obtained can be used as the basis for develop land and forest fires early warning system in Indonesia. This research use GIS (Geographic Information System) for processing mapping of physical parameters which consists of Land Use Map, Topography Map and Soil Map in Sumatra and Kalimantan to get the forest and land fires danger map. The results of the mapping areas that vulnerable to forest and land fire based on the physical parameters resulting from this study have uniform patterns with the distribution and density of hotspots in the Sumatra and Kalimantan over the last 10 years (2006-2015). This is reinforced by the result of mapping accuracy test, where the percentage number of hotspots during the last 10 years both in Sumatera and Kalimantan area which is exactly vulnerable up to very vulnerable to land and forest fires danger by 74%.

Abstract

Information on the value of land in Indonesia is still very minimal and difficult to be known by the public, particularly in the area of Bengkong, it also results in the presence of new activity for land speculators who want to grab a great adventage in providing price and land value pricing-related information. The purpose of this research are to create the value land zone map (VLZ) that illustrates the value of land is relatively the same as delivering lines and different colors on each value owned and accompanied the factors whisch affected it, as well as presenting a price comparison between the village and the land on map in the form of the web. Spatial analysis and AHP can be used for weighting for the most influential parameters and has no effect, so that the AHP can be useful to assist in decision making. VLZ obtained by observation in the field using a questionnaire and interview against the respondent. Observation and interviews done with the technique of sampling purposisive namely the selection of the sample with the groups in the number of smallest unit of score. Samples taken as many as 25 in order to achieve an accurate data. The value of the acquired land price is the current value of land prices. The result of the research in the form of web map VLZ with 6 classification of land price, the prices that Bengkong area concertrated settlement areas as Rp 3.500.000/sqm for the land prices are the highest in the village of Sadai and Rp 327.000/sqm for the lowest land price was in the village of Tanjung Buntung.
