      Abstract: As education area, campus or university is full with various activities which have an impact on the existence of land-use or land-cover. The variation of activities dynamically change the shape of land-use or land-cover within the campus area, thus also create variations in Land Surface Temperature (LST). The LST are impacting the coziness of human activity especially when reaches more than 30 oC. This study used the term Urban Heat Signature (UHS) to explain LST in different land-use or land-cover types. The objective of this study is to examine UHS as an Urban Heat Hazard (UHH) based on Universal Temperature Climate Index (UTCI) and Effective Temperature Index (ETI) in University of Indonesia. Thermal bands of Landsat 8 images (the acquisition year 2013-2015) were used to create LST model. A ground data known as Air Surface Temperature (AST) were used to validate the model. The result showed an increased level of maximum temperature during September-October since 2013 until 2014. The maximum temperature was reduced in October 2014, however it increased again in August 2015. The UTCI showed “moderate” and “strong heat stress”, while EFI showed “uncomfortable” and “very uncomfortable” categories during that period. This research concluded that build up area in UI Campus highest temperature on UI campus based on UHS. Range UHS in Campus UI on 2013 (21.8-31.1oC), 2014 (25.0-36.2oC) and 2015 (24.9-38.2oC). This maximum UHS on September (2014 and 2015) put on levelling UTCI included range temperature 32-35oC, with an explanation of sensation temperature is warm and sensation of comfort is Uncomfortable, Psychology with  Increasing Stress Case by Sweating and Blood Flow and Health category is Cardiovascular Embarrassment. This UHS occurs in September will give impact on psychology and health, that’s become the UHH of the living on education area.

    • Authors: Adejompo Stephen Fagbohunka
      Pages: 11 - 16
      Abstract: Abstract: The paper underscores the infrastructural facility and the student’s academic performance in Adekunle Ajasin University, Akungba Akoko, Ondo State, Nigeria. Thirty questionnaires were administered through a systematic sampling technique in each of the six faculties making a total of 180 questionnaires. The paper has found out a positive relationship between the student’s academic performance, power supply and health facilities. However, the internet facilities and transportation facilities were not adequate, whereas water supply was adequate. A test of the impact of infrastructural facility on the student’s academic performance, using a Chi Square statistical technique revealed a significant value of 177.1 at 0.05 % level. The paper recommends that the existing facilities should be upgraded and significantly improved by the government; urgent attention should be given to the development of the internet facilities and transportation sector of the University. Also, private partnership should be encouraged in the infrastructural development of the University.

      Abstract: Agricultural drought is characterized by lack of sufficient moisture in the surface soil layers to support crop and forage growth. Indicators of agricultural drought often are precipitation, temperature and soil moisture to measure soil moisture and crop yield.  This study aims to assess spatiotemporal of drought in the Tihama Plain, which is one of the most important agricultural areas in Yemen, where contributes about 42% of the total agricultural production in the country. In recent years, the Tihama Plain faced changes in the rainy season, which reflect negatively on agriculture production and water security in the area. In this study the Standardized Precipitation Index (SPI) was used to temporal evaluation of the situation of drought, also it has been used Geographic Information Systems (GIS) in order to show the spatial variability distribution of drought in the study area. The analysis results by SPI-6 showed that the years 1984,1991,2002, 2003,2004,2005,2006 and 2008 were the most affected by drought during the study period 30 years (1980-2010), also show that the year 1991 was the worst years of drought experienced by the study area. Based on the fact that the study area is the most important agricultural areas in Yemen, it is recommended a study the drought and its impact on agricultural crops in the area.

      Abstract: The frequency and intensity of flood disasters have become serious issues in the national development process of Nigeria as flood disasters have caused serious environmental damages, loss of human lives and other heavy economic losses;  putting the issue of disaster reduction and risk management higher on the policy agenda of affected governments, multilateral agencies and NGOs. The starting point of concrete flood disaster mitigation efforts is to identify the areas with higher risk levels and fashion out appropriate preventive and response mechanisms. This research paper explored the potentials of Geographic Information System (GIS) in data capture, processing and analysis in identifying flood-prone areas for the purpose of planning for disaster mitigation and preparedness, using Benin-Owena river basin of Nigeria as a unit of analysis. The data used in this study were obtained from FORMECU and were entered and use to develop a flood risk information system. Analysis and capability of the developed system was illustrated and shown graphically. The research showed that over one thousand settlements harbouring over ten million people located in the study area are at grave risk of flooding. Key words: Flood, Risk, Vulnerability, Geographical Information System (GIS), River -Basin

      Abstract: This research was conducted in the surrounding areas of a university, Universitas Muhammadiyah Yogyakarta (UMY), which is administratively located in Tamantiro Village, Kasihan District, Bantul Regency, the Special Region of Yogyakarta, Indonesia. It aims to formulate the regional management of the surrounding areas as they have been presenting the indications of urban sprawl. It used a qualitative method with research data obtained from in-depth interviews to 22 informants including governmental agencies (7 informants), academics (6 informants), entrepreneurs (5 informants), and villagers (4 informants). The informants were sampled using purposive sampling method. Data processing and analysis were conducted using qualitative descriptive method, i.e. (1) data reduction, (2) data presentation, and (3) data conclusion. Data validation and reliability tests were conducted using source triangulation method. The results show that the stakeholders proposed various management strategies to improve the positive impacts and, at the same time, reduce the negative impacts of urban sprawl. These management strategies include (1) consistency in implementing spatial planning regulation, (2) spatial synergism in development planning, implementation, and monitoring, (3) assistance to the native people and the migrants, and (4) integration between the university and the village.

      Abstract: ABSTRACTAgriculture sector has an important contribution to food security in Indonesia, but it also huge contribution to the number of poverty, especially in rural area. Studies using a global model might not be sufficient to pinpoint the factors having most impact on poverty due to spatial differences. Therefore, a Geographically Weighted Regression (GWR) was used to analyze the factors influencing the poverty among food crops famers. Jambi Province is selected because have high number of poverty in rural area and the lowest farmer exchange term in Indonesia. The GWR was better than the global model, based on high value of R2, lowers AIC, MSE and Leung test. Location in upland area and road system had more influence to the poverty in the western-southern. Rainfall was significantly influence in eastern. The effect of each factor, however, was not generic, since the parameter estimate might have a positive or negative value. Keywords: poverty, food crops farmer, spatial analysis, Geographically Weighted Regression

  • The Political Geography of Voters and Political Participation: Evidence
           from Local Election in Suburban Indonesia

    • Authors: Pitri Yandri
      Pages: 57 - 64
      Abstract: The praxis of political issue including voter turnout and political participation does not exist in a vacuum. Therefore, geographical and spatial issues are frequently engaged and even embedded into it. Thus, this article is written with one purpose: to investigate the spatial relationship of voter turnout and their political participation. As stated earlier, the complexity of the political analysis based on geography will take us on a multidimensional approach that includes social, cultural and economy. However, this article starts the discussion from spatial analysis by using a map that illustrates the administrative boundaries of a region, then determining whether one region is adjacent to another. In this case, Moran’s I is used to determine the spatial autocorrelation of voter turnout and political participation. The result indicates that the voter turnout and political participation in one region are adjacent to each other. Possible reasons for the result are discussed in this article.

  • Sandbar Formation in the Mesjid River Estuary, Rupat Strait, Riau
           Province, Indonesia

    • Authors: rifardi rifardi
      Pages: 65 - 72
      Abstract: At the aim to clarify the relationship between the sandbar  formation and lithogeneous sediment discharges, the sedimentological aspects of the Mesjid River Estuary are revealed by various analysis. The samples of bottom surface sediments and the suspended sediment were collected at 50 stations in the estuary using grab and van dorm samplers. Oceanographic observation were also carried out  at the stations. The Mesjid River Estuary receives lithogeneous sediments mainly from the Mesjid River’s drainage areas which play important role on the formation of sandbar which is shown by  a belt-like area (0.5-1.0 m depth) in the area off the river mouth. The sandbar might become a sandbank in 20 to 40 years later. High suspended sediment up to 354.61 mg/l indicates the river mouth receives lithogeneous sediments. Total of 926  ton/day of the sediments supplied by the river are deposited 0.024 m/year into the area.

  • Developing of Total Suspended Sediment Model Using Landsat-8 Satellite
           Image and In-Situ Data at The Surabaya Coast, East Java, Indonesia

    • Authors: teguh hariyanto
      Pages: 73 - 79
      Abstract: The decrease of  coastal-water quality  in the Surabaya  coastal region can be recognized by value of sediment named Total Suspended Sediment(TSS )( Hariyanto , 2011) . For that  we need a system for monitoring  sediment value in the coastal region of Surabaya which  regularly measures TSS. The principle to monitor  TSS  value using Remote Sensing methods is by Landsat-8satellites image processing using some ofTSS-models then those are analyzed  for looking its  suitability with TSS value resulted by direct measurement in the field ( in-situ measurement). The  TSS value from the all algorithms on the same coordinate with the in- situ data are validated using linear regression to investigate their correlation. The resutt which obtain the highest correlation value  is TSS algorithm by Budiman (R = 0.991) hence this Algorithm can be used to investigate TSS-distribution representing the coastal-water quality on Surabaya which has TSS value between 75 mg/L up to 125 mg/L.

      Abstract: This study aims to build a model of beef cattle farming development using spatial approach in rural areas of the southern slopes of Merapi Volcano Sleman Regency of Yogyakarta after eruption 2010. Samples were taken Glagaharjo sub-district (Cangkringan district) as impacted area and Wonokerto (Turi district) as unimpacted areas. Survey method were used to land evaluation analysis and  Geographic Information System (GIS) software for spatial analysis. Materials were used RBI map in 1:25 000 scale, map of land use, landform, slope, and IKONOS imagery (2015. Analysis potential of land capability  for forage cattle using the production unity in kg of TDN per AU. The research result showed that based on the land capability and suitability class maps, both villages had the potential of land carrying capacity of cattle feed of 2604.84 AU in Glagaharjo and 2162.26 AU in Wonokerto. However, further research to explore the potential of agricultural land use to develop smallholder model of beef cattle farming in both villages was still open to the researchers.

  • Geography and Communal Conflict in Indonesia

    • Authors: sujarwoto sujarwoto
      Pages: 89 - 96
      Abstract: The determinants of communal conflicts in Indonesia have been widely documented. However, most of them ignore geographical aspects of communal conflicts. This paper examines geographical determinants of communal conflicts in Indonesia. Data comes from the 2008 Village Potential Census (Podes) and official statistics which consist of communal conflict information across all Indonesia’s districts (N districts = 465). Results from spatial dependent model show that communal conflict to be spatially dependent through latent determinants, meaning that communal conflict clusters because of clustering of latent determinants within district. Rather than religious and ethnic heterogeneity, communal conflict is positively associated with poverty, economic inequality, elite capture, and weak capacity of districts to manage fiscal resources.

  • Use of Geographically Weighted Regression (GWR) Method to Estimate the
           Effects of Location Attributes on the Residential Property Values

    • Authors: Mohd Faris Dziauddin, Zulkefli Idris
      Pages: 97 - 110
      Abstract: This study estimates the effect of locational attributes on residential property values in Kuala Lumpur, Malaysia. Geographically weighted regression (GWR) enables the use of the local parameter rather than the global parameter to be estimated, with the results presented in map form. The results of this study reveal that residential property values are mainly determined by the property’s physical (structural) attributes, but proximity to locational attributes also contributes marginally. The use of GWR in this study is considered a better approach than other methods to examine the effect of locational attributes on residential property values. GWR has the capability to produce meaningful results in which different locational attributes have differential spatial effects across a geographical area on residential property values. This method has the ability to determine the factors on which premiums depend, and in turn it can assist the government in taxation matters.
