Abstract

Abstract. Indonesia as an archipelagic country has marine area larger than land area, 13.446 islands (Geospatial Information Agency, 2012) with coastline 95,181 km (Indonesian Maritime Council, 2008), making Indonesia has natural resources of the sea more than the natural resources on land. This potential conditions of marine resources is seen as an opportunity for Indonesia as a developing country to build excellence in coastal and marine field. But during 68 years of the nations independence, maritime sector has notproved as a sector that can be seeded by the nation and relied by Indonesian people. Based on the literature, one of the main problems in Indonesian ocean is marine boundariesdetermination are unclear and unresolved causes uncontrolled human intervention in managing marine resources and chaotic patterns of use of marine resources, uncontrolled utilization even destructive.  This paper discusses about marine boundaries problems that is happened in Indonesia whether they arise from the country and from abroad. Until now much of Indonesia marine boundaries with neighboring countries are still unfinished. Implementation of UUD1945 Article 18 and 25 junctoLaw No.32/2004 juncto Regulation of the ministry of home affairs No. 1/2006 about determination and demarcation of boundaries (including marine boundary) hasn’trealized. There is no certaintboundaries of exploitation and utilization activities in ocean spacebyinstitutional (sector), nor implementation of marine management in eastern Indonesia that more often faced with the existence of customary marine management caused overlapping claims marine areas that can raisemarine boundariesconflicts between regions, sectors or customary.  In general, marine cadastre deals with how states define, organize and manage marine boundaries in their countries. This condition causes marine cadastre concepts in continental countries such as America, Canada, and Australia can not be fully implemented in Indonesia. Marine cadastre concept for Indonesia should adopt the archipelago needs, in the context associated with UNCLOS82, Law No. 32 2004 about regional autonomy, Law No.27 2007 about coastal management areas and small islands, and customary marine authority. This paper is part of dissertation research in order to build model of marine cadastre system uses evaluation definition approach and geospatial information principles.  Keywords: Marine Boundaries, Marine Cadastre, Archipelagic Perspective

Abstract

Abstract. The coastal area is a center of social activity and economic activity. As a center of social and economic activities, the coastal areas are potential areas to be developed and utilized as a result that there will be changes and land uses in the form of land use. Land use is a form of physical influence of human activities on the earths surface. Land use of an area associated with population growth and activity. The increasing population and the more intense activity in the population of a region on the increasing impact of land use change. To view and control the land use changes land use monitoring needs to be done at a certain time. Monitoring of land use can be done by identifying and interpreting information from remote sensing data in the areas of land use that will be monitored. By comparing the two forms of land use from remote sensing data of different time at the same location, will be obtained by changes in land use as well as statistical data coupled with social and economic conditions. It can be in terms of changes in the land analysis to the socio-economic aspects of the local population. The results showed that land use changes with the addition of the largest area occurs on the settlement in the amount of 43.05 Ha while, land use changes  with the greatest reduction occurred in the vast open land in the amount of 93.08 Ha. Land use changes had positive impact on social aspect with increasing population of that work as many as 21,538 people and economic aspects with poverty who reduced amounted to 1.55%. Keywords : Land Use, Land Use Change, Social Economy, Coastal Area

Abstract

Abstract. Coastal zone is a transition area which always influenced by the changes of the land and ocean. The changes may occur due to the tide, current, wave, wind, sea water intrusion, runoff, contamination, or continental shelf area. As an effect, erosion and sedimentation phenomenon are occurred and could cause the changes of coastline shape. Kecamatan Muara Gembong which belongs to Kabupaten Bekasi is located in the Northern Coast of Java Island. Due to its geographical location, this area is threatened by the risk that is caused by erosion and sedimentation in the coastal zone. Therefore, study in this area is needed in order to identify the changes of the coastline. Coastline mapping through spatio-temporal LANDSAT-7 ETM+ satellite imageries is one of the methods to conduct this study. It uses satellite images from year 2000 – 2012. These images were processed by two visual image enhancement methods, named ratioing and BILKO algorithm, so that the visual differences between the land and the ocean could be identified. After the images were processed, coastline digitizing could be done annually from both methods. The result of this study is that there is a significant amount of erosion occurred in the coastal zone of Desa Pantai Bahagia and Desa Pantai Sederhana with the value of 139.05 Ha and 91.65 Ha from the ratioing method whereas the result from BILKO algorithm method is 141.56 Ha and 103.82 Ha. Desa Pantai Mekar has the least reduces, that is 30.44 Ha from ratioing method and 26.27 Ha from BILKO algorithm method. Based on Net Coastline Changes, the area of Kecamatan Muara Gembong from year 2000–2012 has reduced 346.54–349.56 Ha with the speed average of erosion that has been obtained is 28.88–29.13 Ha/year. Keywords: coastline changes, LANDSAT-7 ETM+ satellite imageries, erosion, sedimentation

Abstract

Abstract.Tropospheric delay is the amount of distortion caused by the deceleration of satellite’s signal propagation due to the influence of troposphere. The value of this delay is certain effect of elevation angle that is called the slant delay. In the processing of GPS signals correction, the value of slant delay will be converted using a mapping function to the measured value of the zenith delay which became known as the Zenith Total Delya (ZTD). Zenith value is an accumulated value of the tropospheric delay along the signal’s path at the zenith direction. The value of ZTD can be determined by GPS technique. In Geodesy, ZTD is a nuisance parameter, but for meteorology, it is a parameter of interest, which causes from variability of the atmospheric constituens. The section of ZTD, i.e. Zenith Wet Delay (ZWD), could be derived by substracting Zenith hydrostatic Delay (ZHD) component from ZTD. By surface temperature readings at the GPS receiver, the retrieved ZWD can then be transformed with additional uncertainty into an estimate of the Precipitable Water Vapor (PWV). The aim of this research is to study temporal behavior of PWV at ITB campus, as it is revealed from GPS measurements. According to the research that has been conducted, we obtained some results, i.e. The data quality and strategy which were used in processing could affect the result, In particular, we found that, within 20 minutes, maximum and minimum PWV values could reach 85.2 mmand 6.4 mm, respectively. It may indicate that the atmosphere above the studied are varies highly. Temporal condition in observation point that appears in result such as at 12.00 – 18.00 WIB often shows significant irregular anomalies of PWV that influenced local area observation. Keywords: GPS, PWV, temporal analysis, ZTD.

Abstract

Abstract. Agenda 21/1992 chapter 17 and Indonesia Republic Act No. 27/2007 provides a view on the management of coastal zone with the concept of sustainable development. The manifestation of the concept has been transformed into various forms of coastal research management strategies in accordance with the categories and characteristics of state elements (governance, territory and population). A dynamic development of Indonesia as a developing country, makes the issue due to land scarcity and human population arise. By using geographic-demographic approach, the correlation between every element produce different forms of relationships, which one of them is land ratio. The pattern of land ratios tend to be unbalanced (shrink) spatially and temporally. The pattern of these trends impact the entitys land (land use change, changes in land area, land productivity, environmental degradation) and the entities of population (odds work, consumption, the value of income, and poverty). Thereby, the government and local governments should have an appropriate management strategy to the dynamics relationships of human resources and coastal resources along with all the characteristic. This study examined the extent to which the condition of the land ratio can be optimized within the framework of coastal resource management strategies according to the principles of balance and sustainability. The framework is made through a process of transformation of existing land ratio to the optimum ratio of land. Research methodology begins with mapping land ratio from the global level, national level, to the study in the coastal region of the Madura Strait. Spatially, the dynamics approach of coastal resource use unit area of the ecosystem (DAS Brantas and Madura Strait) and administrative area (county and city). From the temporally land use and population dynamics data from 1971-2005 and the prediction of condition land ratio in 2014 and 2025. Optimization process is done by theory of system and theory of optimization approach. Results of spatial land ratio optimization are examined using three location theory approach, there are Alferd Weber, Melvin Greenhut- A Losch and Walter Isard. According to the optimization result, location theory analysis and geographical association, the conclusion of this research is that the spatial optimization method can describe the geographical correlation between land resources and human resources variable, so this method can be used to measure land ratio value and to measure the principle of balance, fairness and equity between regions. Optimization of spatial land ratio in coastal resource management strategies can be placed as a feedback in any planning process, utilization, monitoring and control. Keywords: the state elements, spatial optimization, the ratio of land, geo-demographic, geographical associations, coastal resources, sustainable development.

Abstract

Abstract. The change of sea level in the western Pasific Ocean is one of the biggest change in the world. This is caused by steric and eustatic factors. In the period of 1992-2012, the total change of sea level in this area based on the Topex/Poseidon satellite data, Jason 1 and Jason 2, was 6. 982 ± 3.493 mm/year. Based on the temperature and salinity from Argo floats for the period 2000 – 2013,  the obtained high streic changes in sea level in the region is about 14.352 ± 13.002 mm/year. The result is a based on high steric sea level relative to 900 dbar pressure. To find the rise of eustatic sea level that caused by the changes in ocean mass, linear regression performed on the data Equivalent Water Thickness (EWT) of monthly GRACE satellites in the period January 2004 to April 2013. The magnitude of the linear trend EWT changes in this area is -0.4026 ± 0.1073 mm/year. This study concludes that the correlation between EWT and the SLA value is more significant than the correlation between high steric sea level and SLA. But further investigation is needed to determine the factor that contributes more to changes of sea level in the study area. This occurs due to the presence of still considerable correlation between the high steric sea level and ocean mass which is the independent variable in the equation of total sea level . To minimize these correlations , observations required high steric and ocean mass with a longer time span. Keywords : The change of sea level, steric, eustatic, the western Pasific Ocean, linear trend

Abstract

Abstrak. Gunung api Papandayan adalah gunung api yang terletak di Kabupaten Garut, Jawa Barat. Gunung api dengan ketinggian 2665 meter di atas permukaan laut itu terletak sekitar 70 km sebelah tenggara Kota Bandung. Gunung api Papandayan merupakan salah satu gunung api aktif di Indonesia. Salah satu metoda pemantaun aktivitas vulkanik gunung api adalah dengan metoda deformasi. Dalam melakukan penelitian deformasi yang terjadi, digunakan data pengamatan survei GPS (Global Positioning System). Pada dasarnya survei ini dilakukan untuk mengetahui pola dan kecepatan deformasi yang terjadi pada Gunung api Papandayan. Dari analisis unsur deformasi ini, dapat diketahui karakteristik deformasi yang terjadi pada gunung api tersebut. Pada Gunung api Papandayan deformasi yang terjadi dipengaruhi oleh tekanan magma dari dalam gunung. Dari analisis yang dilakukan, sumber magma dalam dan sumber magma dangkal mempengaruhi aktivitas gunung. Pada tahun 2003-2005 terdapat dua sumber magma dimana di sana terjadi proses inflasi. Pada tahun 2005-2008 hanya satu sumber yang mempengaruhi dimana di sana terjadi proses deflasi. Pada tahun 2008-Juli 2011 terdapat dua sumber  magma yang mempengaruhi dimana di sana terjadi proses deflasi dan inflasi. Pada Juli 2011-Agustus 2011 terdapat satu sumber magma dimana di sana terjadi proses inflasi. Pada tahun 2003-Agustus 2011 terdapat dua sumber magma dimana di sana terjadi proses deflasi dan inflasi.Kata Kunci : Survei GPS, deformasi, model Mogi
