Abstract

Abstract. This research bring together the development and implementation of marine fishery information system model and study of up and down stream component that are indicated have significant impact for the increasing of fisherman prosperity in Cilauteureun fishery port (PPP Cilauteureun), Pameungpeuk. The model results a daily potential fishing zone (ZPPI) map that was distributes to the fisherman. Most of the fisherman in Cilauteureun are labor fisherman who have salary that is lower than the minimum regional salary/UMR (44% of UMR). Developed ZPPI maps contain information about the location of potential fishing zone, fishing route and distance, time and capital needed, and additional information about current, wind, and wave height. Operational cost efficiency resulted from the utilization of the ZPPI maps are 54% respectively for the small capacity vehicle/MT (less than 10 GT) and 41% respectively for bigger vehicle/KM (10-15 GT capacity). The efficiency also cause the MT labor fisherman salary increaing up to 219% (achieve 98% of UMR). The integration of upstream components (ZPPI maps, vehicles and equipments facility, and human resource quality) and downstream components (catchment result sales, traetment, and distribution system) also has important role for the prosperity progress of Cilauteureun local fisherman.Keywords: fishery information system, fisherman prosperity, fisherman salary increasing, fishing zone map, operational cost efficiency, PPP Cilauteureun.

Abstract

Abstract. Sumatra is located near the place where the collision between Indo-Australian Plate and Eurasian Plate heppened. When Indo-Australian Plate moves below Eurasian Plate, the friction that occur between both plates causes the strain is being accumulated. The strain that exceeds the elastic limit will be released as an earthquake. GPS observation in Sumatra was conducted to analyse the velocity of vector displacement and the heterogenous of tectonic strain on the surface as one of the tectonic indication to earthquake mitigation in the future. The result from data processing shows vector displacement in Sumatra has northeast direction that indicate inter-seismic and southwest direction that indicate post-seismic. The strain distribution is extension that indicate post-seismic equally scatteres dominantly in zone where happened Aceh earthquake on 2004, Nias earthquake on 2005, Bengkulu on Sptember 12th 2007, and earthquake on Mentawai Island on September 13th 2007. While strain as compression shows Sumatera still has inter-seismic effect.Keywords: compression, earthquake, extension, GPS.

Abstract

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

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
