This paper was aimed at providing the pollution status of Jabi Lake, FCT Abuja. 13 parameters were tested from raw water collected four sampling points. The physicochemical parameters were measured using Hanna multiparametric meter, while transparency was measured using Secchi disc. Dissolved oxygen, Biological and Chemical oxygen demand were measured titrimetrically using standard method. The concentrations of the metals were determined in triplicates. Flame atomic absorption spectrometer was used in the analysis as well as descriptive statistics (mean, standard deviation) and standard error. The Nigerian Industrial Standard and WHO guidelines for domestic water were used to compare the results of the water from the lake. The study reveals that the mean turbidity ranged between 21.6 – 24.2cm and is above the recommended limits of both WHO and NIS. The range of pH was between 6.3 and 8.8. pH is within a neutral range. The study reveals that the mean value of TDS and electrical conductivity is below the recommended limit of both WHO and NIS guidelines. The study shows that there is high concentration of some heavy metals (Cd, Cu, Ni, Mn, Zn, and Fe) in Jabi Lake. Cd, Zn, Fe and Ni are above the permissible limits of the NIS and WHO guidelines, which is an indication of pollution. The study, therefore, recommends that proactive measures be taken on environmental laws in FCT and that environmental/health worker and non-governmental bodies be active in enlightenment campaigns that will alert members of the public to the harm being caused to this important ecosystem.

Experiences with natural disasters have intensified recent efforts to enhance cooperation mechanisms among official disaster management institutions to community participation. These experiences reveal a need to enhance rapid mapping technical assistance to be developed and shared among young scientists through a summer school. However, the question arose of how effective this summer school to be used as a tool to increase scientists’ understanding and capacity. This study sought to evaluate the extent to which human resource capacity building can be effectively implemented. The methods used for this evaluation is through observations, questionnaires and a weighted scoring based on knowledge, skills and attitudes’ criteria. The results indicate a significant improvement in knowledge (94.56%), skills (82%) and attitudes (85.20%) among the participants. Even though there are still gaps in participants’ skills, the summer school was found to be an effective way to train the young scientists for rapid mapping.

The measurement of 2D geo-electrical using Wenner Alpha configuration was conducted in the shore line of northern part of Ternate island, in order to know the depth of interface and to analyze the aquifers in conjunction with estimation of ground water potential. Water quality analysis is also conducted in some dug wells, such as in situ water temperature, electrical conductivity, pH, turbidity, dissolved oxygen, and salinity.Due to laboratory analysis, the values of measured parameters of water quality from some dug wells meets to the standards referred, especially for drinking water. The result of interpretation from geo-electrical data showed the depth of interface less than 10m. From a drilled well data near shore line, indicate about 5m deep of interface. Base on geo-electrical survey, water quality analysis and field observation can be concluded that Ternate Island has limited potential of ground water, especially related to amount of fresh ground water. Which is now days, no alternative source yet of clean water for domestic use.

In the development process, Information and Communication Technologies (ICTs), which also commonly referred to as electronic media or cyber media have been acknowledged as a new instrument that could facilitate the need of new information and innovation for rural people or farmers. However, several studies reported that extension and communication based-electronic media in developing countries encounter more problems rather than in developed countries. This research aims to investigate the ownership, access, utilization or functions of ICTs for obtaining information supporting the daily life of farmers and for promoting various farming activities in the coastal area of Kulon Progo Regency Yogyakarta. The research method of the study was a descriptive method that has been conducted by a mixed method. The study found that in line with modernization in agriculture, farmers have been using conventional and new electronic media including television, radio and mobile phone with function for getting new information. Conventional electronic media are still dominant while the use of new electronic media has been gradually increasing. Information gathered from ICTs includes social, cultural, economic, health and environmental issues. The use of new electronic media particularly the internet via smartphone has newly started to be utilized among farmers in the coastal farming area who intensively engaged in horticulture crops cultivation mainly for getting and exchange the market information. Information on technological innovation is still dominant among farmers. Better infrastructure and mobility access, improvement of telecommunication network and development of content and format of information provided by new media will be prospective in the future

Parcels data in Indonesia are still stored in 2-dimensional (2D) geometry which are integrated with other attribute data, such as the case with the Directorate of Land and Building Tax Indonesia. Whereas, building taxes assessment refers to a number of details that require the information to be stored in 3-dimensional (3D) forms. This study aims at the use of Building Information Modeling (BIM) technology, which widely used in building asset management in 3D. This research illustrates the usability of the role of BIM in assessing and managing building taxes in Indonesia. The point clouds were obtained using Terrestrial Laser Scanner (TLS) technology. The point clouds processed so that it can form 3-dimensional geometrical apartment. The attributes of the 3-dimensional model integrated with the geometric model using the BIM concept. The results analyzed to assess whether BIM concept was able to fulfill the needs of the 3D fiscal cadastre in Indonesia.

Visual impairment people require a means of information transfer which different from normal people, it needs to be touched or amplified by audio, including maps that apprise them of the objects and events occurring on Earth. Cartographic Sciences have developed tactile maps that offers touchable symbols for supporting blind and partially sighted people in recognizing the spatial distribution of geographical phenomena and their intercorrelation. Creating an informative tactile maps need a specific design of symbol, ancillary information, and map reproduction that meets the need and the capacity of its users. Unfortunately, there has been no international standardization for these map features that could be used as a foundation to build a standardization for our national tactile map. Therefore, this research adopted and modified the designs of tactile symbols published by the National Mapping Council of Australia, the Guidelines for Design of Tactile Graphics by American Printing House, the use of tactile variables by Vasconcellos, the Specifications of Topographic Elements Mapping by Bakosurtanal, and the application of visual variables of Bertin for cartographic mapping. The resultant symbol designs from the modification were applied to develop the tactile maps of Yogyakarta City on swell paper. Then, through interviews with map users (visually impaired people in the city), we evaluated these symbols from two aspects, comprehension of tactile variables and the types of the tactile maps required.

Landsat 8, Landsat Data Continuity Mission (LDCM) satellite, was launched on 11 February 2013 with Operation Land Imager (OLI) sensors. Tis sensor has better radiometric performance than the previous mission, which is quantized in the 12-bit dynamic range due to an increase in the signal-to-noise (SNR) ratio. In this analysis, the spatio-temporal distribution of the propagation of the internal solitary wave (ISW) in the Lombok Strait was extracted from the Landsat 8 images described for the ﬁrst time. Tere were 14 ISW events studied for period 2014 - 2015 using Landsat 8. Te manifestations of ISW recorded on Landsat 8 images were then extracted using digitization method to investigate and measure several parameters and ISW distribution in the Lombok Strait. Te estimation results of the average ISW phase velocity in this study are 2.05 ms-1 with the direction of propagation heading north at an average angle of 19.08°. Tis study has shown that Landsat 8 can be used to monitor and analyze several internal wave parameters in the ocean.

Lack of education among the scheduled castes (SC) population in India may be the main reason for remaining at the lower end of the social structure. Therefore, this study attempts to explore the changing trends in literacy among the SC to find out the determinants of higher education and to explore the major reasons for never enrolling or discontinuing/dropping out from educational institutions among the SC population in India. Using the data from the Census of India and also from National Sample Survey and employing both bivariate and multivariate analysis, the results reveal that though there is an increasing trend in the literacy rate among the SC population, but the rates remain quite below the national average. Gender disparity in literacy is quite evident. The low level of higher education mainly due to reasons like failing in examinations, heavy drop-outs and stagnation caused by their poor socio-economic background. Despite various efforts by the central and state governments to eradicate differences in educational attainment among the social groups through several constitutional steps from time to time there still remain gaps to be bridged.

In this paper, result of moving campaigns of night sky brightness measurement over Greater Bandung area is reported. Though the campaigns were not commenced in ideal condition in terms of cloud cover and moon light contamination, the result is quite convincing. The obtained value of sky brightness range from ~17 mpsas at downtown region to ~20 mpsas at Haurgombong, Sumedang which is more than 30 km away from the city center. It is in agreement with months-length stationary measurements of sky brightness over Bandung, Lembang, and Sumedang. This result can be combined with nighttime satellite imagery from Defense Meteorological Satellite Program Operational Linescan System (DMSP-OLS) to produce the map of sky brightness over Greater Bandung area. This map is important product for regional planning and discussing the prospect of astro-tourism.
