Abstract. The customary communities in Indonesia have employed a range of resource management techniques to limit marine resource use. Localized control over marine resources, commonly known as Customary Marine Tenure (CMT), is the legal and cultural foundation for many of these practices. This paper outlines the general characteristics of CMT in Maluku Islands in which these characteristics overlap with modern right-based coastal management. It also examines the effectiveness of CMT regimes at regulating marine resource use and access by focusing on a particular case from the Ambon Lease. The custom institutional robustness and vulnerability of CMT is assessed by examining various performance criteria for three communities in the Ambon Lease that is Ambon, Haruku, and Saparua Island. These criteria could be identified by coverage of the area, social right holding unit and legality, and its enforcement.Â The results show that a number of historical processes have shaped CMT systems into heterogeneous and dynamic institutions, and that CMT regimes can vary even on small geographical scales. Understanding the circumstances in which CMT regimes are more likely to be successful has facilitated the design and implementation of integrated management fishery between customary and local government institution for protecting particular species and habitats in the region. More generally, the paper proposes that by discerning the effectiveness of local governance institutions at regulating resource use and access taking into consideration that these are embedded in particular customary system contexts.Â This knowledge can also assist in designing integrated management schemes between customary and local governance system. This integration is particularly relevant when these policies are to be implemented in coastal communities that have or have had traditional rights-based coastal management systems of their own that more socio-culturally homogeneous. Given the long history of coastal management, it is now of vital importance to design innovative coastal management prescriptions that integrate engineering and social science research more comprehensively.Â Keywords: Customary Marine Tenure, Integrated Coastal ManagementÂ

Abstract. In each GPS time series data, there are signals which exist and affect the result that has been received, which is called noise. Those noise components will form certain pattern in time series. Basically, time series has periodic component which commonly not being able to be detected directly. To detect which periodic component that dominantly affect the time series, there is a way which is called spectral analysis. With acknowledge periodic component in a time series, we can know the characteristic of the time series and then we can determine how many parameters will be needed to do curve fitting. There are two approximations in fitting, it is either linear fitting only or linear fitting with including periodic component. As a comparison between these two methods, we need to be estimate displacements velocity rate in a year. From the analysis that has been done, the result is that the biggest difference of displacements velocity rate between these two methods is 3.7 milimeters per year.Keywords: displacements velocity rate, fitting, periodic component, spectral analysis, time series.

Abstract. The availability of light in the water column determines the euphotic zone and constrains the type and the vertical distribution of benthic species. Diffuse attenuation coefficient (Kd) is an important apparent optical property (AOP) that provide information about the attenuation of the spectral down welling solar irradiance with depth in the water. Ocean color Satellite provide global coverage of optical water quality parameters at spatial and temporal resolution. Several empirical and semi-analytical models are commonly used to derive Kd at wavelength 490 nm Kd(490) from ocean colour satellite sensors. This study present about the diffuse attenuation coefficient, Kd(490) using semi-analytical approach. The dynamic Kd(490) in the Berau Estuary water was studied and compared with those derived from ocean color satellite sensor, Medium Resolution Imaging Spectrometer (MERIS). The study indicated that Kd(490) of in situ measurement had the best correlation with the Kd(490) of MERIS data of remote sensing reflectance (Rrs) derived with FUB (Free University Berlin) algorithm (R2=0,84). The dynamic of Kd(490) from MERIS data on different date indicated that the Kd(490) have a similar pattern and decreased when going to offshore.Â Keywords: MERIS, Secchi disc depth, tropical coastal water, Kd(490), a semi-analytical approach

Abstract. Cultural heritage is an asset owned by any country that can tell behavior of peopleâs life there. The story of the cultural heritage â one of them contained in archaeological object â is a story that have historical value and can not be replaced so we need to make the right efforts to conserve them, such as documenting the archaeological object we have, in this case is Sewu Temple Complex in Klaten, Central of Java. Conservation mean as branch of archeology that tries to preserve and manage archeological object to a lot of academic-practical interest (Yuwono, 2003). Geographic Information System that have storing, showing, and analyzing data ability, in the scope of conservation can used by archeologist for conserve or reconstruction. Principle of the development of virtual reality GIS for cultural heritage conservation is more directed to the terms of visualization. The several stage of this study are design the spatial database, data extraction â includes 3D modeling, 3D model georeferencing, 3D model segmentation, database implementation, and visualization process. The expectation result for this virtual reality GIS is an application that will represent 3-D visualization of Sewu Temple area, 3D models of each part of temple at LOD 2, LOD 3, until LOD 4. Beside that the application can be used for Temple reconstruction for more efficiently and effectively process.Â Keywords : Database, Virtual Reality GIS, Conservation, 3D ModelsÂ

Abstract. One of the GPS kinematic processing software that developed in the current is RTKLIB. RTKLIB is the software which people can downloaded free and used free for it. This software can also perform data processing in fast and the data processing can be integrated in post-processing and real-time. In this study, the ability of RTKLIB tested by using GPS observation data with variations of the baseline length when earthquake not occured and earthquake offset detection from the GPS baseline processing results during earthquake. In this testing the stability of the GPS data processing results are ascertainable and it can be seen also the ability and reliability of the software in detecting earthquake offset. For comparison of the data processing results quality with RTKLIB, in this study selected TTC (Trimble Total Control) to process the GPS baseline of the same observasions From the results of GPS baseline processing with RTKLIB and TTC, it seems that RTKLIB results have better stability than TTC. In short baseline category have standard deviation less than 1 cm, in medium baseline category have standard deviation between 3-6 cm, whereas in long baseline category have standard deviation 3-8 cm. On the offset detection of earthquake, RTKLIB have ability to detect offset in more of baseline length variations than the TTC.Â Kata Kunci: GPS Kinematik, Offset Gempa, RTKLIBAbstract.

Abstract. Increasing activity at the infrastructure construction in urban areas causes a revolution in the infrascructure become vertically oriented, means using the space either above or under the land surface. Law Number 16 Year 1985 about Stack Houses have given the arrangement about land registration based on space. This arrangement only to regulate use of space vertically, which the space has land rights and become unseparated part from its building. Therefore, itâs necessary to have a regulation about use of the space above the ground which has nothing related with its land rights and basically itâs about authorization of space based on volume, therefore it is necessary to apply cadastre 3D concept in its regulation.Â The study case in this research is Beringhajo Market (Pasar Beringhajo) building which is located on Pabringan Street. The data that are collected consist of physical and juridical data. The 3D cadastre that applied is using Full 3D Cadastre Alternative Combined 2D/3D method as the most accurate method for regulating use of space above the land surface. This method is also used as reference for designing the form of rights and spatial data for use of space above the land surface. The rights form is a product from processing physical and juridical data, while spatial data form is only from physical data processing.Â From this form designing, a new rights institution which is called rights for using space above the land surface (Hak Guna Ruang di Atas Tanah/HGRAT), and spatial data in volumetric land which is formed in 2.5D registration map and document of measurement certificate, was formed.Â Keywords : 3D cadastre, use of space above the land surface.Â

Abstract. Water vapor is a principal element in the thermodynamics of the atmosphere and plays an important role in clouds condensation, which eventually can affect the radiative energy balance. Water vapor cobservation is essential for monitoring global/regional scale of weather and climate changes. However, high variation of water vapor concentrations makes it difficult to observe accurately using the conventional meteorogical observation technique (radiosonde), which is limited in both space and time. Nowadays, accurate observation of water vapor can be accomplished by the Global Positioning System (GPS). In this research, we use 14 continuous GPS stations from Bakosurtanal to observe temporal characteristic of water vapor concentration over West Java region.Keywords: GPS, NCEP, radiosonde, topographic, ZNHD

Abstract. The ability of radar signals to penetrate cloud is one advantage to be used in tropical regionto monitor objects on the surface from the space. Synthetic Aperture Radar (SAR) is onetechnique in radar remote sensing that can be utilized for marine applications such as surfacewaves monitoring, ocean current circulation detection, oil slick monitoring and shipdetection. In order to assess the ability of SAR technique for ship detection, we analyze SARdata acquired by full polarimetric and interferometric airborne SAR in L-band type-2 (Pi-SARL2) from Japan Aerospace Exploration Agency (JAXA). This research explains the strategy inSAR data processing for ship detection application in Lembeh Strait, North Sulawesi Sea. It isfound that long wavelength i.e. L-band is able to identify ships on the sea with incidence angleof radar beam greater then 50 degree gives the best signal clutter ratio between signal fromthe ship to sea clutter variation. The identification includes the size estimation and thelocation. Horizontal-Horizontal (HH) polarization can identify ships clearer in calm seacondition, whereas Horizontal-Vertical (HV) polarization is better in severe sea condition.However, it is difficult to estimate the speed of moving ships on the sea and the shipsmaterial. It is also found that by combining SAR data with VMS (Vessel Monitoring System)data it is possible to identify ships without VMS and useful for improving security issue inmarine sector.Â Keywords: SAR, ship detection, polarization, VMS

Abstract. Two important things in the scope of Geodesy and Geomatics engineering and geodetic science is positioning and coordinates. The position is defined simply as the existence of an object to other objects , while the coordinate is defined as a position statement quantitatively , or others mentioned in the definition of the coordinates is a quantity (numerical) to declare the location or position of a point (object) in a chamber (field) . To ensure consistency and standardization of a coordinate , which applies to the local system to the global (world) , it is necessary to declare the existence of a coordinate system . This system is called the coordinates reference system or Geodetic Reference System , with elements of a constituent or parameter consist of Reference Frame and coordinates Reference System on the earths static system , and the reference system , coordinates and Datum Reference Frame coordinates on the earths dynamic systems . Datum Coordinates further divided into several types of Datum Static, Semi Dynamic , Dynamic , Semi Kinematic and Kinematic .What Geodetic Reference System which is generally used in the global scope ( the world ) will be discussed in this paper . Hope this theme can be one basis when we as a community of Geodesy and Geomatics , or even national community select or determine what the true Geodetic Reference System . This paper will also discuss specifically Geodetic Reference System in several countries .Â Keywords : Positioning, Coordinate, Geodetic Reference System, Coordinate Datum

Abstract. Indonesia as an archipelagic country has marine larger area than land. With approximately consist of more than 13.466 islands (Geospatial Information Agency, 2013) and 99.093km coastline (Geospatial Information Agency, 2013), making Indonesia has more abundant natural resources of the sea than in land. This potential condition of marine resources is seen as an opportunity for Indonesia as a developing country to build excellence in coastal and marine field. However, after 70 years of its independence, maritime sector has not proved 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 the unintegrated nature of utilization activities between institutional (sector), local government (provincial and city/county) and customary that caused overlapping claims marine areas that may result in marine boundaries conflicts.This paper discusses aboutintegration constructionconcept of marine utilization elements in Indonesia. Integration concept can be constructed by marine cadastre elements (right, restriction, and responsibility), integration principle and legal certainty principle in Law No. 4/2011 about Geospatial Information, Law 1/2014 about Coastal Management Areas and Small Islands, Law 23/2014 about Regional Autonomy, and Law 32/2014 about Marine.Keywords: right, restriction, responsibility, integration principle
