Abstract

3D modelling of buildings in Google Earth in Batam city, Indonesia is very important for knowledge about facility, infrastructure, and others.Three-dimensional (3D) visualisations are an interesting method for representing model outcomes. This research In Tunjuk island with coordinate, at Latitude: 0.984123°, and Longitude: 104.225606°, with technical terms, there are two alternative routes for implementation, and they both share the same starting stage. In (Figure 5) visible visual measurements of the master plan that has been made has a length 141.99 metre and width 54.25 metre with location at Latitude 0.984593° and Longitude 104.228073°. In (Figure 5) visible visual measurements of the master plan that has been made has a length 92.96 metre and width 135.46 metre with location at Latitude 0.984593° and Longitude 104.228073°. This paper presented a rapid visualisation tool for supporting the joint decision making in evaluation of design/renewal proposals in Batam City, Tunjuk Island, Indonesia. 3D building using Google Earth (GE) and combaining Geographic Information System (GIS) system be done officially on a sampling or auditing basis by a professional body or by researchers, or it could be done by volunteers and user groups.

Abstract

Tanjung Bemban is one of the seas found in the Nongsa sub-district, Batam city which is currently developed as a tourist attraction. This research aims to find out the hydro-oceanographic component, which consists of tide and the current and wave pattern in the sea of Tanjung Bemban Nongsa. To collect the data regarding tide, Tide Pole method, using measuring sign, is used, To collect data of sea current, Float Tracking (Lagrangian) method, by measuring distance and displacement of floating objects in the sea, is utilized, To collect the data of the wave, Wave Pole method, by measuring wave height, is employed. Based on the result of the research, it is clear that the tide of the sea is categorized as the semi diurnal, since there are two tides in one day with identical height, which occur sequentially and regularly. The highest flow reaches 260 cm and the lowest ebb 19 cm in the 4 days of observation, with 15 minutes interval. The measuring of ocean current is carried out for every 30-second intervals. Current velocity in Nongsa sea ranges from 0.02 m/s to 0.26 m/s. The current moves from east to southwest and west, even though some move northwest and north. Wave height is quite low, between 18 cm and 23 cm. Hydro-oceanographically, the Tanjung Bemban Nongsa area can be developed into a strategic tourism area

Abstract

Indonesia is an archipelagic country with a total marine area of 5.9 million km², consisting of 3.2 million km² of territorial waters and 2.7 km² of Exclusive Economic Zone waters, not including the continental shelf. With the vast waters in Indonesia, sufficient information about the tides is needed. Limitations of terrestrial tide data amidst the increasing need for marine information can be overcome by using global and regional tide models. This study uses the regional tidal data model released by BIG (Geospatial Information Agency) and the global tide model TPXO9 and GOT (Goddard Ocean Tides). From the two global tidal models, the tidal harmonic constant values are extracted at the tidal observation point in Kabil. Evaluation of global and regional tide models is carried out by comparing the amplitude values of the main harmonic constants of the tide models of global and regional tides with the amplitude values of the harmonic constants of terrestrial tidal measurement data to obtain a comparison of accuracy. The results of this research show the value of main tidal harmonic.
