Distribusi Musiman Total Suspended Matter (TSM) di Laut Surnbawa (117" - us· Edan s· - 9· S) telah dilakukan. Data TSM tersebut diperoleh dari 75 stasiun pengukuran pada bulan September 2005 dan 98 stasiun pengukuran pada bulan November 2005 dan April 2006. Besaran sebaran TSM diperoleh dari hasil perhitungan besaran turbidity yang diperoleh dari pengukuran dengan menggunakan alat CTD ( Conductivity, Temperature and Depth) Sensors. Besaran TSM yang diperoleh dari besaran turbidity menggunakan rurnus TSM = 0,65 Tur+ 1,17 (r = 0,85) (Hoshika dan Tanimoto, 1997). Distribusi sebaran TSM pada saat musim hujan menunjukkan bahwa besarnya bervariasi dari L060 sampai 2.951 mg/1 dengan rata-rata sebesar 1.152 mg/1 (n=98), di lain pihak pada saat musim kemarau distribusi sebaran TSM menunjukkan bahwa besarnya bervariasi dari 1.060 sampai 2.899 mg/1 dengan rata-rata sebesar 1.111 mg/I (n=75). Distribusi sebaran TSM secara vertical dari permukaan laut sampai dengan kedalaman 20 meter menunjukkan bahwa terjadi perbedaan yang signifikan antara musim kemarau dan musim hujan. Pada saat musim kemarau distribusi sebaran TSM pada permukaan laut sampai dengan kedalaman 20 meter mempunyai variasi yang kecil (dari 1.079 sampai 1.599 mg/1); Pada saat musim hujan distribusi sebaran TSM pada permukaan laut sampai dengan kedalaman 20 meter mempunyai variasi yang sangat besar (dari 1.079 sampai 2.698 mg/1). Distribusi sebaran TSM dari kedalaman 20 meter sampai dengan 100 meter menunjukkan pola yang sama antara musim kemarau dan musim hujan. Distribusi sebaran TSM pada permukaan laut (dekat sungai/muara) menunjukkan bahwa terjadi perbedaan sebaran antara musim kemarau dan musim hujan. Demikian juga dengan distribusi sebaran TSM yang diperoleh dari data satelit menunjukkan bahwa terjadi perbedaan sebaran antara musim kemarau dan musim hujan. Perbandingan antara data in situ dengan data satelit menunjukkan bahwa koefisen korelasinya sebesar -0-753 untuk periode penelitian tersebut.

The results of this study indicate: (1) Characteristics of waste in Pakraman Padangtegal Village consisted of 83.88% organic waste, 7.24% plastic waste, 4.42% paper waste, 2.22% bottle waste, glass waste at 1.28% and metal waste at 0.96%; (2) public perception in waste management in Pakraman Village, Padangtegal that most of the people in Pakraman Village, Padangtegal, already know about the definition of waste and the danger of waste if it is not managed properly. Besides that the community also knows the difference between organic and inorganic waste so that the process of sorting waste in the place provided can run well, and the community's perception of waste management services has gone well with the transportation of waste twice a day; (3) the participation of the Pakraman Padangtegal Village community in waste management has played a role in various stages of waste management, starting from the sorting, garbage collection and garbage disposal, which complies with waste regulations and maintains the quality of the environment in Padangtegal Pakraman Village. The participation of the tourism industry in the process of waste management in Pakraman Village, Padangtegal, can be seen as being involved in the process of sorting waste and paying monthly fees and waste fees. The community participation in the waste management process is to help the government to socialize the waste management process by carrying out waste collection activities every week and provide a place for the waste management process. Suggestions in this study are that waste managers will immediately add facilities and infrastructure for waste transportation and accelerate the expansion of waste management in the village of Pakraman Padangtegal. Keywords: Waste Management System, Pakraman Village

The purpose of this study were to know the effect of pearl oyster culture activities to the water quality(physical, chemical, biological parameters), and the sediment of culture site, waters quality status of pearloyster culture site as well.The research was done at 10 stations, which were 9 stations located around pearl oyster culture site, and1 station located at out of pearl oyster culture site (as control). Results showed that the sources of pollutionwere from pearl oyster feces and biofouling produced from cleaning of pocket and its shell. An in organicmatter of the feces produced (50.52-78.75 %) was higher than the organic matter (21.25-49.48 %). The amountof biofoulling trash increased with the size and dominated by organic matter. Sea water quality observed wasunder sea water quality standard of marine organism (aquaculture) decided by government, except phosphate.Twenty four species of plankton collected, consist of 4 phylum, that were Bacillarophyta (diatom),Protozoa, Arthropoda, and Mollusca. Plankton Diversity Index showed the level of low to high pollutioncondition indicated ecological suppression and decreasing of waters quality. The amount of total bacteria andVibrio spp. at all stations were normal, that was less than 106 cfu/ml.Integrated physical, chemical and biological parameters assessment found that pollution index was 2-3,mean of low pollution. Result of Cluster assessment indicate that there was real characteristic differentiationbetween first group (1-9) and second group (control). First group was around the pearl oyster culture waters,and second group was out of the pearl oyster culture waters. So the pearl oyster culture activities affected thewaters quality.

Waste is one source of greenhouse gas emissions (GHG) that has methane gas form which caused an early multi-dimensional, massive and complex problems. The rapid increase of garbage volume entering landfill, annually result a high garbage dumps in the Suwung Landfill area. It should have been considered a handing solution for example by converting the methane gas content in the waste into a useful value added product. The objective of this research is determining the amount of electrical energy that can be produced through methane gas emission at Suwung Landfill. The characteristic and composition of waste could give effect to the formation of methane emissions. The research on the composition and characteristic of waste were done by sorting 1 m3 of garbage sample from new garbage entering landfill. Garbage is divided based on the source of DLHK waste, market waste, and private waste. The volume of waste that went to Suwung Landfill in 2016 calculated 1.296.438 m3 which was dominated by organic waste (78,1%). The density of the waste that went into Suwung Landfill, based on the research's results, amounted to 135,09 kg / m3, there fore could be assumed that the weight of waste that went to Suwung Landfill in 2016 was 175.135,81 tons. Based on these data, the number of 136.785,13 tons of waste, which was organic waste, could increase the concentration of greenhouse gases in the atmosphere if this situation does not manage properly. Gravimeter method is using for measures the dry matter content value of waste. From the measurement, the results obtained the waste components that have the highest dry matter content is from rubber and leather garbage (76,52%) while the lowest dry matter is food waste (19,13%). By using calculations based on IPCC 2006, it was found that the amount of methane emissions could be generated by the waste at the Suwung Landfill in 2016, amounted to 3.535,06 tons. Based on the energy equivalence table, the electrical power that is generated from the potential methane emissions at the Suwung Landfill is 6,66 MW.

The Changjiang River is the largest river in China with an average discharge of 9x1011 m3 /year . The Changjiang river supplies about 80% of total discharge of fresh water from rivers around the Yellow Sea, East China Sea and Bohai Sea. Its monthly mean transport has a large seasonal variation from 103 m3s-1 in January to 4.8x 104 m3s-1 in July around an annual mean of 3 x104 m3s-1 , and large inter annual variation in the annual mean from 2,2x 103 to 3,5 x 103 m3s-1 during the 19-year period from 1970 to 1988 (Yanagi, 1994 ). The East China Sea Current, associated with the Changjiang discharge, flows southward along the Fujian and the Zhejiang Coast of China in winter and Northeastward to the Cheju island in summer, which forms thin low salinity plume called Changjiang Diluted Water (CDW) in summer (Breadsley. et al , 1983, 1985; Hu, 1994, Guan ,1994).CDW moves differently in season. It moves southward in winter and eastward in summer according to its salinity distribution. The relation between wind and movement of the low salinity water also has been suggested in many ways.Generally all of drifter moved northeastward at first, then after 10 days each drifter moved to different sites. Each drifter moving though velocities is about 0.1 m/s and 0.2 m/s. Most of drifters were generally moving to northeastward to the right of the wind direction at these events. It indicates that the sudden changes of drifters trajectory are caused by abrupt changes of winds.Temporal variation in salinity gradually increase during the drifters were in the moved eastward . The salinity rapidly increase during the typhoon passage. Before and after the salinity rapidly increase during typhoon passage, it was mostly constant or very gentle.The vertical velocity generated by wind just after deployment drifters for ten days in drifter deployment in 2007 was about 10-5 – 10-6 ms-1. The vertical velocity during typhoon passage on August 2007 was larger than on passed the area. It is suggested that there was significant divergence in the surface layer during the typhoon passed the area ,resulting in the larger upward vertical velocity in this region.

Human activities around the estuary of the Manggar river in Balikpapan produce waste disposal and cause heavy metal contamination such as lead (Pb) and cadmium (Cd) in water bodies. The contaminant can endanger the life of aquatic organisms. It can also occurs heavy metal bioaccumulation in the body of the aquatic organisms. The results show that the heavy metal content of Pb and Cd in water, sediment and water biota indicated that the estuary of the Manggar River was contaminated by heavy metals. The content of Pb and Cd in water is 0.276 mg/l and 0.020 mg/l, in sediments is 24.7 mg/kg and 4.52 mg/kg, and in the biota is 4.20 mg/kg and 0.80 mg/kg. This means that fish and shells taken from the waters around the estuary of the Manggar River are not safe for consumption because they can interfere the human health.

The development of marine transportation in Denpasar City followed by increasing number of visiting tourists who came to Denpasar City. This situation will contribute to air pollution problems. The purpose of this study was to determine the emission load produced by sea transportation in Denpasar City and the distribution of emissions gases such as NOx, SOx, HC, PM10, CO and CO2.Emission load calculations based on the guidelines of the EMEP Corinair Guidebook using Tier 3, which the emission factors used refer to the CORINAIR GB 2013 1.A.3.d. The results showed a total emission load from non-road mobile sources of marine transportation in the Denpasar city such as NOx is 14,583.69 tons/year, SOx by 85.49 tons/year, HC by 746.05 tons/year, PM10 at 503.53 tons/year, CO at 123,123.58 tons/year, and CO2 of 1,457,909.95 tons/year. Distribution of the source of pollutants mapped using GIS (Geographic Information System) shows that the emission load of NOx, SOx, HC and PM10 are likely identical, which mostly distributed around Benoa Port, but CO2 and CO have different patterns . The pattern of distribution of NOx, SOx, HC, and PM10 with the highest intensity follows the contours of the ships from Benoa Port. CO gas distribution pattern follows the contours of the ship from the Serangan Port and Sanur Port, CO2 gas distribution pattern almost evenly in almost all flow well from the Serangan Port, Sanur Port and Benoa Port
