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. 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. 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. Keywords: Customary Marine Tenure, Integrated Coastal Management

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, it's necessary to have a regulation about use of the space above the ground which has nothing related with its land rights and basically it's about authorization of space based on volume, therefore it is necessary to apply cadastre 3D concept in its regulation. 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. 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. Keywords : 3D cadastre, use of space above the land surface.

Abstract. The geodetic approach based on extraterrestrial survey measurements can be used to study phenomenon, especially to monitoring of material movement characteristic. Landslide is one of prominent catastrophe that continuously affecting in Indonesia, especially in rainy season. In mountainous terrain and areas of steep slope of Indonesia, landslides are frequent, especially where land cover has been removed. Landslides destroy not only environment and property, but usually also cause deaths. Landslide mitigation is therefore very crucial and should be done properly. The velocity and acceleration of several monitored point covering the landslide zone area can be estimated using the geodetic approach. Knowing the relation among these three variables in spatial and temporal domain will be useful for identifying the characteristics of landslide. This information can then be used for better strategy of landslide hazard mitigation. Accuracy of the use of kinematic models for prediction of avalanche characteristics need to be validated so that mitigation will be done correctly. Validation is done by doing a comparison between model predictions and the size of the data and statistical tests for the feasibility of prediction of each point of the GPS monitor. Validation is known that the predicted results at some GPS monitor point is not suitable for use. With the vector of the movement of materials, we know the direction and scalar, velocity and acceleration of material displacement. The movement of landslide materials at Ciloto Zone dominated north-west to south-easterly direction and speed to slow very slow (creep). Keywords: accuracy, characteristics, kinematic model, landslide.

Abstract. Land subsidence is a phenomena that has been commonly occurs in big cities around the world. Especially in Indonesia, Bandung as the one of big cities in Indonesia, has been identified for land subsidence. This land subsidence is suspected to ground water explotation by the factories which are located around Bandung basin. Land subsidence has caused many problems, such as damage to houses, buildings, and infrastructures (roads, bridges, etc.), and as the most serious problem is that land subsidence can increase the size of areas susceptible for flooding. In 2010 was noted that for almost the whole year, in the south Bandung experienced a terrible flood. Seeing the causes which is caused by land subsidence, it is a necessary to do charachteristic mapping of land subsidence. As one of the method that will be use for monitorizing the land subsidence is using GPS (Global Positioning System) survey and InSAR (Interferometry Synthetic Aperture Radar). In this paper, will be explained about land subsidence that occur in Bandung from GPS data. Keywords : GPS, groundwater, InSAR, land subsidence.

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. Semarang is the capital of Central Java province, located in the northern coast of Java island, Indonesia. Land subsidence in Semarang has been widely reported and its impacts can be seen already in daily life. Based on the estimation from Levelling, Interferometric Synthetic Aperture Radar (InSAR), Microgravity and Global Positioning System (GPS) survey methods, land subsidence with rates of up to about 19 cm/year were observed during the period of 1999 up to 2011. Results derived from GPS since 2008 up to 2011 show that land subsidence in Semarang has spatial and temporal variations, with spatial average rates of about 6 to 7 cm/year.Based on the site visit surveys, the impacts of land subsidence can be seen in several forms such as cracks in buildings, damage of infrastructure (road and bridges), tilting and damaged houses, and wider expansion of coastal flooding (tidal flooding). Tidal flooding and tilting and damaged houses frequently occurs in the area where the subsidence rate is high (northern part of Semarang). Cracks in buildings and damage of infrastructure (road and bridges) occur in the boundary of large subsidence area and the less. Keywords : GPS , land subsidence, damages, coastal flooding, Semarang
