Abstract

The damage of coastal ecosystems are no longer dominated by human activity, but the condition of global climate change were also influenced. Climate change impact on the environment influencing the coastal management paradigm. This study emphasizes on how to develop a adaptation strategy of coastal zone management due to the impact of climate change through remote sensing approach, Geographic Information Systems (GIS), and adaptation strategies analysis. Location of research conducted in the Region of Segoro Anakan Bay, District Ngadirojo Pacitan. The results showed the impact of climate change is affecting the area and production of seaweed culture in the form of tectonic conditions aggravated by silting waters. To combat the effects of climate change, the adaptation scenario is implemented to intensification and extensification of land use, alternative livelihoods, minawisata as a combination of all three.

Abstract

The objectives of this research are: (1) to study the characteristics of aquifer, distribution and chemical types of groundwater in the research area; (2) to measure the consentration of major elements (HC03-, Cl-, S042-, Ca2+, Mg2+, Na+, K+) and minor elements (S2-, NH4+) as indicators of leached contamination in the groundwater; and (3) to establish the spreading of contamined groundwater by leached. The grid sampling method was applied in this research. The grid dimension is 1 cm x 1 cm measured in the 1:25000 scale of Indonesian Topographic Map. The groundwater samples were taken randomly within the grid. Not the whole study area covered by the map was grided but only the surrounding area of Piyungan Landfill and the area lower than Piyungan landfill were grided. The groundwater samples were taken during the rainy season because during the rainy season there were more leached produced from Piyungan Landfill. The groundwater samples were examined their physical and chemical qualities using the legal standard quality in Yogyakarta Province. Spatial analysis using maps and graphics were applied to examine the spreading of contimined groundwater by leached. The spreading of unconfined groundwater in the study area was not equal distributed but it seems to be controlled by the landforms. There were an increasing elements content of Cl-, Ca2+, Mg2+ and HCO3-, as well as dissolved oxygen, NO3- and S2- in the groundwater contamined by leached. The zonation of the spreading of groundwater contamined by leached was categorized into three class, i.e., central (location of landfill, well number 1 0), transisional (well number: 11, 12, 13, 15), and primary (well number: 8, 14, 16, 17, 25, 26) zones. The zonation of groundwater matched with the analysis of groundwater quality by the distance from the Piyungan Landfill.

Abstract

Settlement means a place (spatial) or an area where population conentrated on and live in together to make use of the environment to survive direct and develop their living. Pattern and distribution of the settlement constitute a closed connection. The settlement distribution deliberates the fact of where the settlement exists or is not obtainable in an area; while the settlement pattern constitutes a distribution characteristic which has much more connection with the effect of the economical historical and cultural factors. There are some measurement methods of the distribution pattern i.e with the neighborhood analysis formula (t) where if t = 0 it means the settlement pattern conentrates, t = 1 shows the random settlement pattern (uneven distribution), while if t = 2,15 shows the uniform (homogeneous) settelement pattern. The second method is the Demangoens Index (C) which only considers the total of the population, besides C score of the concentration, random, and uniform of the settlement pattern are not detected. Another measurement method is score per “grid square”. The method of R scale is also applicable in the measurement, in which R score is concerned with 0 – 2,1491; if score of R = 0,7 it shows that the settlement pattern would be in group; R = 0,7 – 1,4 means an uneven distribution and R = 1,4 – 2,1491 shows the evenly distribution of the settlement pattern.

Abstract

The purpose of this study was to analyse the dynamics of carbon stocks changes from land cover into land settlement in the Padang City, West Sumatra. Method to formulate the change of land cover into land settlement in the Padang City is the analysis of Landsat Imagery 5+TM 1988, Landsat 7+ETM Image of 1998 and Landsat 7+ETM Image of 2008. Stratified Sampling Technique was Purpose Composite plot refers to the technique, but in this study carried out modification to the size of the plot which is then converted to the extend of each hectare of land cover. Estimating tree biomass using the equation according Kattering allometric, (2001). The result of the research conducted found that the dynamics of carbon stocks always decline from 1988, 1998 and 2008. This is caused by a reduction in forest area, shrubs, gardens, and fields are consistently due to the increased amount of land used for settlement.

Abstract

Not only does poverty in developing country face decline of relative imbalance, but they face the increasing of absolute poverly as well. One of the characteristic of developing country is signed by growth population rapidly. Economic development prospect doesn’t apart from ratio between quantity of population and land suitability. The limitedness of land that be done by farmer cause the decline of agriculture production, besides, the growth of wotk opportunity increase, the employment is restricted. Some main  problems that must be faced by now are; the distribution of income, work opportunity, man power quality, and many alternative approach to be sub mitted to reach the economic growth by distribution.

Abstract

Masalah yang sering terjadi dalam evaluasi sumberdaya lahan permukiman, adalah ketidakseimbangan antara kesesuaian secara fisik lahan, dengan kesesuaian secara sosio-ekonomis. Di samping itu permasalahan yang muncul, adalah dalam penentuan batas yang berbeda ada satuan lahan. Satuan lahan secara fisik menggunakan dasar batas fisik, sedangkan secara sosio-ekonomis mengikuti satuan luasan mendasarkan pada batas administratif. Demikian juga adanya perbedaan ketersediaan data, yakni data aspek fisik bersifat kuantitatif sedangkan data sosio-ekonomis bersifat kuantitatif, sehingga merupakan masalah dalam analisisnya. Oleh karenanya, didalam teknik penentuan batas satuan lahan, serta teknik analisis kuantitatif data sosio-ekonomis memerlukan teknik kuantifikasi data kualitatif. Hasil kajian ini menunjukkan bahwa penggunaan batas administratif desa untuk satuan sosio-eknomis lahan dapat digunakan secara tepat, walaupun satuan lahan secara fisik bervariasi secara rinci. Penggunaan data sekunder potensi desa, baik di pedesaan ataupun perkotaan dari aspek sosio-eknomis cukup representatif untuk mendukung evaluasi sumberdaya lahan permukiman baik pedesaan maunpun perkotaan.

Abstract

A study of spatial disttribution of urban failities and its impact on settlement pattern had been conducted. Southern part of Surakarta Municipality is chosen as study area. The aim was to study the correlation between spatial distribution of urban public facilities and settlement pattern. To obtain the settlement pattern and urban facilities distribution, manual photo interpretation and field survey method were used. The data were analyzed using geographi information system and statistical analysis tools. Map overlay module in the P Ar/ Info was used in order to join each variables of this research. To know the correlation between spatial distribution of urban facilities and settlement pattern, the multiple regression technique was used. The result shows that there was a positive signifiant relationship between urban public facilities distribution and settlement pattern. It means that the more distributed of urban publi facilities the better of settlement pattern (dense – uniform – large size building). Finally, condition of settlement pattern depends on how the goverment was able to manage the distribution of urban failities.

Abstract

Studies about population immobility, especially immobility associated with climate change-related disaster, are very limited. As a consequence, the explanation of population immobility in disaster prone areas is still blurred. This study contributes in explaining population immobility by exploring the typology of residents who did not move from disaster-prone areas. The survey was conducted towards the residents of Kampung Tambak Lorok Semarang, which is prone to three disasters simultaneously i.e. sea level rise, land subsidence, and tidal inundation. The study sample was 235 heads of households selected using proportional sampling area technique. Data were collected using a questionnaire consisting of two parts: (1) demographic, social, and economic characteristics of people who did not move from disaster prone areas; and (2) staying intention in disaster prone areas. Data analysis used descriptive analysis by using table and graph of respondent characteristic and relation between respondent characteristic and staying intention in research area. Three (3) typologies have been identified, namely: Type-1 are residents who wishes to stay; Type-2 are residents who still have not decided whether to stay or move; and Type-3 are residents who do not want to stay/want to move. Each of these typologies is described by place of birth, age, length of stay, education, occupation, and income. The understanding of the typology of residents living in disaster prone areas is important as inputs for policy-makers, especially regarding the relocation of people from disaster prone areas to be effective. The results of this study also contribute empirical evidence to the migration theory debate at the micro level, namely that the staying intention is a key element in the black box of immobile decision-making from disaster prone areas.

Abstract

The technical Remote Sensing and Geographic Information System (GIS) had been used to detet vegetation changing of natural forest due to management differences. The target of the study were to determine classification method of satellite imagery in operational scale so that the method can be transfered and applicable for the user. The studied was done at forest concession of PT SLJ-IV (Sumalindo Lestari Jaya-IV), Yanjung Redeb, east Kalimantan Province. Landsat TM with 7 bands and high resolution of 1994 and 1996 were used to differentiate the condition before and after cutting in 1995. The analysis of the Landsats were only in the area where the TPTI (Indonesian Selective Logging System) and TPTI (Indonesian Strip Logging System) system applied. Based on the analysis and field check, it was found that the impact of logging caused decreasing dense forest about 21,3% and inreasing secondary forest around 6,3%. The highest dynamic of each band was band first and the lowest was band second. The differences in the mean of 2 band will give a more clear appearance of the  imagery.

Abstract

The information of rain water quality in Indonesia is rarely recorded, where as it is important for the region in which the source of fresh water is unavailable. Rain water composition is mostly ascertained by water vapour and ions which are available in the atmosphere during vapouration. In fact the rain water composition of coast region is sea water like and rain water chemical composition of urban are then become HNO3 and HSO4, while rain water of active vulcanic region eventuality has a high sulphur-wombed so that its quality sulphuric-acid. For the region in which the source of fresh water is unavailable the rain water is previously sterilized. Sterilization is consecutively done by adding salts, killing all bacteria, spores, and filltering.
