As a regional income barn, the Nusa Penida Tourism Area needs to be managed comprehensively by involving all available resources, by encouraging new thinking about managing tourism that synergizes with environmental sustainability in the sustainable environment of the Nusa Penida Tourism Area. Tourism can increase economic growth but create a burden on the environment, so that Nusa Penida tourism becomes environmentally friendly tourism to support the development of green tourism. Progress in tourism impacts the environment, causes social and cultural changes in society and impacts the carrying capacity of land and water from the massive tourism development in Nusa Penida. For this reason, it is necessary to formulate a model of environmental management that is relevant and has been developed.This study uses a systems approach with the Interpretative Structural Modeling (ISM) method to formulate an environmental management model in the Nusa Penida Tourism Area. This method can be used to help a group, in identifying contextual relationships between sub elements of each element that forms a system based on ideas / structures or determinants in a complex problem (Saxena, 1992).The environmental management model in the Nusa Penida was formed based on government initiatives by involving all stakeholders as representatives of the Nusa Penida community and involving other elements such as non-government organizations and universities. In the management of the environment, institutional arrangements that specifically handle the environment and tourism of Nusa Penida must be formed with the government as the initiator and formed in a participatory manner. The recommended model of environmental management needs to be applied carefully and continued with the formation of institutions by involving the affected community sectors in Nusa Penida's environmental management and tourism.Keywords: tourism, model, management, environment, Nusa Penida

I Gusti Ngurah Rai Bali International Airport is the second highest airport in activity level in Indonesia. Flight activity in this airport increases every year, with an increase of 20% from 2011 until the end of 2012. The research aimed to identify how much the LTO (Landing-Take-Off) emission activity in I Gusti Ngurah Rai Bali International Airport. The purpose of this research was to identify how much the emission is and the effect of LTO activities towards the ambient air condition of CO and NOx around the airport. Three measurement points and three days recent flight were applied to understand the emission spreading characteristic in every LTO phases. The three phases of LTO which are consisted of take-off phase, taxi in phase and landing phase, were the main focus of this research. The three recent flights were on Monday 5 of May, on Wednesday 7 of May and on Saturday 10 of May in 2014. Regression bifilar linear statistical analysis method was employed to identify the effect and how big the CO and NOx emission contribution towards the ambient air quality. The results of this research showed that the emission of aircraft activity in LTO phases was effected by the ambient air concentration of CO and NOx. It was proved with the result from F test simultaneous with significant level average 0,033 < 0,005 and with r value that exists between 0,77 – 0,97 with mean contribution was 79,1%. Take-off phase was the phase that produced the biggest NOx gas emission compared to the other phases. When the aircraft did the take-off phase, the thrust was used reached 100%, the purpose was to produce the big energy. The combustion that happened in take-off phase in aircraft machine classified in perfect combustion, also this thing effected the phase to produce the smallest CO gas emission compared with the other phases. Taxi in phase was a phase that produced the biggest CO emission between the two other phases, it was happened because the thrust needed just 7% only so the combustion in aircraft machine classified in imperfect combustion and it was effected the CO emission was increasingly while the landing phase was the phase that produced the smallest CO and NOx gas emission compared to the other phases. Measurement results of the CO and NOx concentration in every point in three days recent flight was still under the quality standard that has been settled appropriate in Government Act number 41 year 1999..

On August 21, 2009 an offshore oil rigs located in Block West Australia territorial was exploded. About 500.000 liters/day of crude oil was spill out to the Timar Sea. To detect the oil spreading, this study used MODIS satellite data from 21 August 2009 until 15 March 2011. Besides that, data of wind speed and wind direction, coordinate of pollutant point sources, and Exclusive Economic Zone (EEZ) line are also used to know the covering area of the oil was entered into Indonesian territorial. The oil was classified by visual interpretation methods, these are: dark spot detection, feature extraction and classification. As the result, oil spill covered area increased since August to September 2009. Oil spill on the sea surface then decreased drastically until November 2009. This was due to dispersant spraying which made the oil settled down. But, when a tropical cyclone occurred in December 2009 and January 2010, the settled oil appear again in sea surface but it spread out in various location. This study shows that MODIS data can be used to monitor spreading of oil spill since no cloud cover. The maximum oil covered area was occurred on 24 September 2009 about 7,996-40 km2

Based on the data of Environmental Status of Bali Province Year 2009, Sungi River is the one of ten rivers that have experience quality degradation which contaminated by waste. Pollution parameters that have exc.eeded the quality standard, are: BOD, COD, Total Phosphate, Total Coliform, and Faecal Coliform. It requires to concerned because Sungi River as the point area for drinking water in Tabanan (data of Environmental Board of Bali Province). Purpose of research is to determine the characteristic of pollution source which will be impact to the changing of water quality in physical, chemical, and biological in middle and down stream area, detern1ine the pollution index in up stream, middle. and dow stream area of Sungi River. Water parameters that will observe are: temperature, pH, turbidity, TDS, TSS, DHL, DO, BOD, COD, Total Phosphate, Total Coliform and Faecal Coliform. The measurement result will compare with the best of water quality, based on the Regulation of Bali Governor Number 8 Year 2007, because of it utilization as drinking water. Result of research shown that the activity in Sungi River dominated by agriculture activity, settlement, animal husbandry, and industry that located in dov.n stream area. The waste that result from the above activities caused the degradation of water quality that shown by the increasing of water parameter indicators, such as: BOD, COD, Total Phosphate, and Faecal Coliform Bacteria. In the middle will increasing and down stream area will get degradation. This condition is inversely proportional to the content of DO as impact of contaminants accumulation, such as: organic waste in middle are, because the water movement is more calm with average water flow is 0,14 m/second compared with the up and down stream area with average water flow are 0,15 m/second and 0,35 m/second. Characteristic of pollution source which effect the water quality at Sungi River in area I caused by llie activities of agriculture, animal husbandry, settlement, and industry, for area II caused by the activities of agriculture, animal husbandry, settlement, and villa. The quality staLus of Sungi Rlver in up stream area still result a good quality water but in the middle and down stream area are get lightly pollution. Water quality parameter which exceeded a good water quality in Sw1gi Rive,· is Total Phosphate with average value is 0,44 mg/I in the middle area, 0,40 mg/l in down stream area and Faecal Coliform with average value is 166/100 ml in the middle area and 152/100 ml in the down stream area.
