The primary production quantity depends on the vertical distribution of chlorophyll concentration inthe water column. The chlorophyll maximum value not always observed near or at the sea surface, butsometimes lies deeper than bottom of the euphotic zone. In this case, the ocean color sensors cannot measurethe chlorophyll maximum value. Vertical distribution of chlorophyll modeled and calculated withdevelopment of Vertical Model Function (VMF) by “Gaussian function”.This research has been carried out in western area of Sumbawa Sea. There were 178 stations of fieldobservations. The data were collected at each 0.5 m depth up to 200 m sea depth. Results processing ofprimary data, with correlations between chlorophyll concentration and depth in every station can show typesof vertical distribution of chlorophyll in all stations. There are five types of vertical distribution ofchlorophyll at Western Sumbawa Sea. The” five types” then classified into two main groups namely areLinear (L) type and Gaussian (G) type. Finally, data were processed to obtained one especially type that is“one type”. The regression analysis was carried out on the parameters in the Gaussian Function, BO, S, h, ?and Zmax for the each type of the vertical distribution of chlorophyll concentration.Vertical distribution of chlorophyll found at Western Sumbawa Sea are Linear (L) type, Linearsurface (LS) type, Gaussian (G) type, Gaussian with maximum surface (GS) type, and Linear with maximumsurface (LMS) type, where with “five types” have nine coefficient determinants (R) which below than 0,25.The regression analysis were modified from “five types” into “two types” and the result was two coefficientdeterminants (R) that below than 0,25. Correlation coefficient with “one type” have better result than theother types which has only one coefficient determinant (R) that below than 0,25.

Most of the tourism area are distributed along the coast that intersects directly with those that result in degradation of the ecosystem inside. The southern region of Bali is one region that have experienced rapid development of tourism activities. The expansion of the tourism area in Tanjung Benoa, Bali occurs to coastal areas and directly contact with underwater habitat such as coral reefs and seagrass beds which can damage the underwater ecosystem. The goal of this study is to map shallow water habitat in densely packed tourist areas Tanjung Benoa, Bali using remote sensing technique. Two satellites dataset (Sentinel-2A and Landsat 8) at different spatial and spectral resolutions were tested using Lyzenga algorithm. The maksimun likehood supervised classification is used to classify the underwater objects and accuracy test were then conducted to to evaluate the classification effectiveness. The results showed that there were three types of shallow water habitats in Tanjung Benoa coastal area, such as dead coral, seagrass, and sand. The accuracy test showed Sentinel-2A images with an overall accuracy of 80,00% and kappa accuracy of 59.27%. had higher accuracy than Landsat 8 images with an overall accuracy of 68,29% and kappa accuracy of 35,43%.

The percentage of solid waste services Denpasar City in 2013 reached 51,8 percent, the limited number and capacity TPS in Denpasar not meet the needs of waste management services in denpasar. The study was to examine the relevant strategies appropriate to the criteria and requirements related to the determination of the location of TPS and the land need. The position of the study is Part Of The City (BWK) Central in Denpasar. Analysis of technical aspects will evaluation garbage production in order to know the ideal needs of TPS, the evaluation of TPS placement based on the function of the area and the land needed. Environmental aspect will analyze the environmental risk due to the presence of a TPS. Analysis of public opinion and the behavior of people will use a questionnaire in the collection of data to be analyzed with qualitative methods as a consideration in determining the location and design of a TPS. Institutional aspect will be evaluated about the understanding DKP (Office of Cleaning and Gardening Services) employees of the City of Denpasar in the management of garbage, especially in the TPS. As for determining the direction and strategy of the management of garbage SWOT analysis was used.Based on the analysis, the need for the addition of TPS to improve the capacity of TPS, the shape of TPS had comply standard of SNI and environmental safety factor. Additions and changes in the shape of TPS also effect land requirement, the total area of land that must be reserved for TPS is 0,40 hectares. Determining the location of TPS is based on the need of the type of TPS over the spatial pattern. Analysis of public opinion on the determination of the location of TPS, it is obtained that the distance of a TPS with the source must be relatively close and the land use is a vacant land. It is also suggested optimizing the role of the DKP of Denpasar by increasing socialization and community development programs in waste management.

The aim of this research is to know the relationship between lemuru fish catch to Sea Surface Temperature (SST), El-Nino Southern Oscillation (ENSO) and Indian Ocean Dipole (IOD) phenomenon in Bali Strait. The results showed, that in the period 2007 – 2016. fluctuations of catches lemuru tends to decline. Sea Surface Temperature (SST) distribution with the lowest temperature 25,28oC at 24,53oC - 27,16oC and the highest temperature is 29,31oC in the range of 28,730C – 30,490C. The lowest temperature occurred in July - September while the highest temperature occurred in January - April. Based on the calculation there is a linkage and relationship between catch and SST as shown on the value of determination and correlation reached 50,0% and 70,73%. Most of the catches occurred in the west season and then the transition II, transition I and East Season. The relationship of ENSO phenomenon to the catch during the El-Nino phase of lemuru catch will increase while in the phase of La-Nina the catch of lemuru will decrease, because time of El-Nino phase of the sea surface temperature (SST) relative low which results in the chlorophyll-a mean case which is a food sources of lemuru fish. Based on Trenberth's theory, (1997), the rise and fall of the ENSO Index of less than six months is not stated in ENSO. From the calculation results during the research of 2007 - 2016 happened three times ENSO phenomenon that is in 2009, 2010 and 2015. At the time of the IOD phenomenon, the IOD (+) phase will result in a decrease in catch while the normal IOD phase and (-) will increase the catch. From the results of this study can also be observed, in the year 2007 - 2011 phenomenon ENSO and IOD have a strong influence on the catch while in the year 2012 - 2016 the influence of the phenomenon of ENSO and IOD has no strong influence caused by the quantity of lemuru fish that have been over exploitation that resulted in the current Bali Strait on Over Fishing status.

Collection and transportation of waste in the Distiict of East Denpasar have not run optimally due to lack of garbage collection and waste transport processes which are 1101 adequate. The research was conducted with a S\1tvey to determine the condition of existing operational waste transportation route followed by following the waste transport vehicles and calculate the time it takes to make one trip transportation and the number of trips in one day. The number of vehicles Uiat will be surveyed in the field is the number of vehicles that serve the Sef'\????ce area of East Dcnpasar DistJ·ict, which consists of dump trucks and arm roll truck. The results showed that the waste transportation operations in the District of East Denpasar have not nm optimally due to lack of bins for the community and a fleet of garbage that is not proportional to the volume of waste generated, the number of transport trip has not been able to reduce the waste. Transport route selection is currently not effective because it ha???? not minimized the di????-tance and travel time. The condition of access to TPA Sarbagita is unfit to be passed by a garbage truck, where the bumpy road conditions can cause damage and inhibit the rate of truck components.

Indonesia is maritime country surrounding by Wide Ocean. Two seasons that always happened in this area have been influence to the situation of oceanography and fisheries zone. The seasons which happened because influence by wind of monsoon, which are West Monsoon, East Monsoon, and the transition condition among both. The fishing ground information used Geography Information System (GIS) and remote sensing (RS) software and can be used for specific purpose. The most fundamental application is for dynamics population and distribution of fish in the ocean ecosystem. Environmental characteristics such as: temperature, thermo clines, salinity, ocean currents, and depth is identify potential fishing use technology of image satellite represent the way of identifying indirectly. From satellite data far identified by interconnected oceanography parameters sliver with fish habitation or potential schooling fish. Between oceanography parameter having relation with life of pelagic fish is water temperature go out to sea and fertility of territorial water area. Map of conducive satellite data, sea surface temperature ( SST) and content of chlorophyll-a the can be obtained by information about oceanography phenomena specially front thermal and upwelling representing potency area as fishing indicator. Fishing vessel usually leave fishing base without exactly knowing location of fishing ground so it always stay in uncertainty potential location of fishing ground, therefore its haul also becoming not surely. Meanwhile, in consequence of uncertainty fishing location, resulted fishing ship passing many time and fuel to looking for location of fishing ground. Successfully of the fishing operation is not depend by experience of fishing master but there are must be have the data where fishing ground located. And application of semi active fishing gear much help fisherman salary and require following by other sub-province especially at the west season, but having to limit by usage mesh size enabled by law or regulation so that small fish do not follow to be caught.
