Abstract

Upaya peningkatan pemanfaatan bahan bakar gas bumi untuk rumah tangga dan pelanggan kecil terhambat karena terbatasnya infrastruktur yang menghubungkan gas bumi dari sumbernya ke konsumen. Kegiatan survei dan pemetaan ini sangat diperlukan karena akan memberikan gambaran eksisting lokasi rencana jalur jaringan gas bumi. Dengan demikian kegiatan perencanaan akan lebih realistis, efektif dan efesien karena memperoleh informasi eksisting kondisi di lapangan sehingga dalam pelaksanaannya nanti tidak mengalami kendala yang berarti. Kegiatan survey dan pemetaan dalam rangka perencanaan jaringan gas rumah tangga ini dilakukan dengan dua metode yaitu, terrestrial dan fotogrammetri jarak dekat. Metode terrestrial digunakan untuk memberikan gambaran potongan memanjang dan melintang sepanjang jalur rencana pipa gas sedangkan fotogrammetri jarak dekat digunakan untuk memberikan gambaran tampak dari udara mengenai lokasi perencanaan jaringan pipa gas serta perkiraan sebaran pelayannya. Dari kegiatan ini diperoleh gambaran mengenai peta situasi, potongan memanjang dan melintang sepanjang jalur perencanaan pipa gas serta tampak sebaran layanan yang terjangkau. Peta-peta tersebut diharapkan dapat digunakan sebagai dasar perencanaan untuk jaringan pipa gas bagi rumah tangga terutama di lokasi yang dilakukan survey dan pemetaan

Abstract

GNSS (Global Navigation Satellite System) is a term used for the entire global navigation satellite system that already operate or are in the planning. some of them namely GPS, GLONASS, and BeiDou. Errors due to less powerful satellite geometry when data retrieval, in teoritik can be resolved with receiver technological advances that was able to capture many of satellite signals. Hi Target V30 is one of GNSS receivers are able to catch GPS, GLONASS and BeiDou signal, with more satellite signals that can be received are expected to improve the accuracy of positioning. From this study is known that the use of BEIDOU satellite not too influential on the GPS satellites, but will add to the accuracy of the GLONASS satellite. This is demonstrated by the existence of a reduction in average value on difference coordinates and RMS error reduce from 1,068 m into 0371 m. The use of GPS + GLONASS + BEIDOU and GPS + GLONASS satellite combinaton provide the best accuracy with the RMS value of the error remain in the millimeter, while the use of GLONASS satellites alone give the worst accuracy among the strategies with the value of RMS error visible to reach 0585 m on baseline C2.

Abstract

One of the acoustic instruments were used for the measurement of the seabed is the Sub Bottom Profiler. This instrument uses a low-frequency acoustic signal which has the ability to penetrate the layers of the ocean bottom up to a depth of several meters. The purpose of the survey using the Sub Bottom Profiler that is to conduct the investigation and identification of coating the ocean floor so that the retrieved information related to seabed stratigraphy. The location of research are on Alur Pelayaran Timur Surabaya. Secondary data is Raw data Sub bottom profiler, RAW data of single beam, SVP and tide data has been processed. The data retrieved from the District Navigasi kelas 1 Surabaya. The location of the research is classified as waters of the shallow waters. There are three layers of sediment. The pattern of seismic reflection data are parallel and subparallel. Thickness between the base of the sea surface with the first layer has a constituent sediments form the sandy mud. Thickness of the layer of sediment volume values the greatest there is between the first and second layers of 8.009.815.18 m³. The total volume of the thickness of the layer sediment 17,945,928.40 m³.

Abstract

Coral reefs are one of the major ecosystems in the coastal region with high biodiversity and resource level. As productive ecosystems with high economic and ecological potential, the existence of coral reef ecosystems must be sustainably managed. One of the areas with high diversity of coral reefs is Giligenting Island located in Sumenep regency. This research was conducted by taking primary data in the form of tidal data, bathymetry data and Side Scan Sonar recordings. From the primary data and then processed until produces 3 dimensional model of seabed features that are then interpreted and analyzed to obtain information about healthy or damaged coral reefs, using underwater geo-tagged photos to validate. The 3-dimensional model has a maximum depth of 7.667 meters and 1.403 meters at minimum depth with an area of 100,536.097 m2. From the interpretation of Side Scan Sonar acoustic images it is found the area of sand feature is 30.79%; the area of mud feature equal to 29.94%; the healthy coral covering 35.75% of the survey area, consisting 10.09% of coral reef barrier reef feature, and 25.66% of small coral reef feature; and 3.52% of damaged coral reef feature from total 43,527.110 m2 Side Scan Sonar survey area.
