Abstract

Waste management in Jembrana District, had been handled by the Environmental Sanitation Department, which in 2012 the amount of garbage in Jembrana District it’s about 684.80 m3. The amount of garbage was large and continues to grow up every day, thus feared that TPA Peh will overload. This problem encourages the needed for Integrated Waste Sites Planning in TPA Peh, where it will accept the loads of Jembrana garbage. The Integrated Waste Site Planning in TPA Peh requires some studies, such as study of the technical aspects, financial aspects and environmental aspects. Based on technical analysis it was known that the garbage of Jembrana district in TPA Peh amounted to 150.56 m3/day. Recovery factor value was 80.33% with 19.87% residue. If this large amount of garbage is not processed, then TPA Peh predicted will be overloud in November 2015. By Integrated Waste Site Planning which is only the residue that wasted on landfill, then it could be extended the lifespan of the landfill until 9 (nine) years and 3 (three) month. Required area in the application of Integrated Waste Site Planning in TPA Peh is 13.701 m2. The total cost of investment in the implementation of the Integrated Waste Site in TPA Peh is Rp. 12.331.282.000.00. Total operational cost is Rp. 5.811.760.000, while the revenue potential of recycling such as composting and stalls selling stuff in 2022 is Rp. 18.390.154.291.56. Net Present Value (NPV) obtained positive value of Rp. 13.933.193.788 with a value of IRR is 45,23% and B / C ratio is 1,159. Environmental analysis on TPA Peh Jembrana by analysis of well water quality around the landfill, is known that most of the physical and chemical parameters are still under the quality standard. Biological parameters are still above the water quality standards based on Permenkes No. 416.Menkes/Per/IX/1990. From the analysis of landfill leachate water quality parameters known for Total Suspended Solids (TSS), Ammonium-free, BOD, COD and biological parameters are still higher then the effluent quality standards compared to Bali Governor Regulation No. 8 of 2007 on Environmental Quality Standards and Criteria Standard Environmental Damage.

Abstract

El Nino-Southern Oscillation (ENSO) is one of the most important climate anomalies humans isconcerned about. It brought many changes in physical of the ocean. The seas of the Indonesian Archipelagoare an artery carrying tropical thermocline water from the Pacific to the Indian Ocean. Termed the'Indonesian Throughflow' (ITF), this transport is driven by the Pacific/Indian interocean pressure gradient.The variability of SST in Equatorial Zone during 1997/1998 ENSO analyzed by using L1 AVHRR satelliteimages from NOAA and in-situ data from TAO/Triton buoy. This study was done in Eastern Part ofIndonesian Archipelago (110oE – 130oE and 4oS – 11oS). This research begun by collecting data in longterm, 1993, 1997, 1998 such as: in-situ data and satellite image. L1 AVHRR satellite images from NOAA toget SST data were used. From TAO/Triton buoy, SST and current data were got. SSH data available from L3TOPEX/Poseidon. SLP and salinity data were got from NOAA-CIRES Climate Diagnostics Center. All thedata analyzed by SOI value to recognize the normal, El Niño, and La Niña conditions. The SOI value wasused in this study available from existing research data.Generally, the SST in northern Lesser Sunda (Bali, Lombok, Sumbawa and Flores) was 0.5 – 1oC higherthan southern part. During El-Nino event on October 1997, the 1 – 2oC cooler SST causes the surfacepressure get higher around Indonesian seas. This phenomenon probably is much influenced by the change ofseason in Indonesia, from hot season to the rain season. But during El-Nino 1997 the 1 – 4oC warmer waterwas occurred in centre part of Pacific Ocean, hence the sea water from Indonesia Sea flown to the PacificOcean. During El Nino conditions, on December 1997, the SSH in southern Indonesia Archipelago wasabout 10 – 40 cm lower than normal conditions and became 10 – 30 cm lower than Indonesian seas. Thiscould be due to the SST in Indonesian seas was higher than southern Indonesian Archipelago causes lowersurface pressure in Indonesian seas. During La Nina conditions, on November 1998, the SSH in southernIndonesia Archipelago was about 5 – 35 cm higher than normal conditions and became higher thanIndonesian seas. This could be due to the SST in Indonesian seas was lower than southern IndonesianArchipelago causes higher surface pressure in Indonesian seas. Water mass would be flowing fromIndonesia seas to southern Indonesia Archipelago. Generally, during 1997 to 1998 the current in Java Seabecame 1 – 3 m/s stronger than normal conditions. During El-Nino 1997/1998 the sea surface temperaturein central Pacific region was warmer than usually, this could be mean the current inverse to the centralpacific from Indonesia seas. Generally, during 1997 to 1998 the current was flows southward throughMakassar Strait, continue to Lombok Strait and go to Indian Ocean. The current in Makassar Strait wasflows about 1 – 4 m/s and about 1 – 2 m/s in Lombok Strait. On June 1997 the current was flows northwardthrough Lombok Strait about 1 – 2 m/s.

Abstract

The aim of this research is to determine the tourist products and to know whether the visual interpretation of remotesensing and GIS tecnology can be applied in tourism in Nusa Dua Tourist Resort. In the preparation stage, it is necessaryto combine data ALOS satellite image with identity ALAV2A044933780 with map, and followed with visualinterpretation of satellite image to obtain temporary results concerning tourist products in Nusa Dua tourist resort. Theresult of satellite visual interpretation was cross checked by insite observations to compare the potentials of coral reef atsea and tourist product on the ground. The combination visual interpretation of satellite image and in site observation oftourist product in Nusa Dua tourist resort enables to obtain spatial mapping for tourism in Nusa Dua tourist resort
