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.

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.

Publisher : Politeknik Negeri Batam

Public Street Lighting (PSL) is a part of road complementary buildings installed on the left, right and/or in the middle of the road to illuminate the surrounding environment. PSLs in residential areas usually do not have a small amount, so it will be difficult if the supervision is done manually. Therefore, we need a system that can monitor and maintain PSL effectively and efficiently. This study aims to prove that the Operations Dashboard for ArcGIS (ODA) can be utilized in monitoring PSL based on Geographic Information Systems (GIS). This PSL monitoring system can be used by the government and private parties to conduct PSL maintenance activities more efficiently and effectively, by providing information about PSL in realtime through widgets contained in ODA, and with the help of a mobile application, Collector for ArcGIS (CFA) as a sensor replacement that functions to carry out data collection in the field. The results of this study indicate that ODA can be used to monitor PSL by showing information about the status, location, type, and number of PSLs damaged.

One of the environmental parameters that need to be monitored is ocean waves. Waves that occur at sea have random, dynamic, and complex movements. Height measurements and wave periods are difficult to formulate accurate and simplification is needed through mathematical equations in the form of sinusoidal. Therefore, the marine information system is very important for data storage media, data processing, and visualization of measurement data so that it is monitored in real-time. This research was made to build a website-based coastal wave height monitoring information system for wave height data display data from the measurement of the wave buoy instrument. This research was conducted by utilizing data from a wave height measuring instrument that was transmitted to an online database. Wave height data is displayed in the form of real-time data, real-time graphs with data sampling of 30 minutes, average data for one day, and average data for one month. Keywords: Wave height, system information, real-time

Batam as a region with a strategic position, located on the international trade route, was developed to become one of the engines of economic growth in Indonesia. However, in its development, Batam faced governance problems that had an impact on the decline in its economic performance. Not only at the local level, but its influence reaches the national level. This study explains the causal relationship of Dual Governance, focusing on aspects of formation, relations between institutions and their impact on development. Using the framework of Holzinger, Kern and Kromrey (2016), this study captures the issue of institutional dualism that has occurred for years and is considered to be the cause of the decline in development in Batam. The study was conducted using qualitative research methods with a case study approach and collecting data from interviews and document analysis.There are several concluding points in this study regarding institutional dualism and its impact on economic development based on Batam’s case. They are the implementation of decentralization, the significance of the pre-existing institution, the similarity between two institution in respect of interpreting and implementing policies and the relationship between intergovernmental relations and economic development. These three factors affect the degree of intergovernmental relations which is directly proportional to economic development. The more intergovernmental relations are, the higher economic development is.

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.

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.

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.
