Abstract

This Article is written with a view to know role and socialization of the autonomous municipality.This Article represent the normative legal research that is concern with legislation approach (the statute approach), case study approach (the case approach), approach by factual (the fact approach) and the approach of analisial legal concept (analytical conceptual approach) and also the bibliography approach (the library approach) that is the collection of the reading materials relaited with this topic of problems..From result of this article we can know that the role and the socialization in the automous municipality still have an illusional character and cannot fulfill clearly and accurately it’s function. Because in the arena of politics the determination process of bribes and corruptiones, so minutes which is agreed at early in the meeting or conclusiones wich is written in the minute of meeting often different from the determined public policies. To diminish these problems we extremely need the essential quarantee that socializational requiamentes or aspirationes which are integrated in the public policies must be based on partisipative statutes concerning with the autonomous municipality.

Abstract

Defining the genetic structure of a particular population of marine turtle is an essential ecological aspect to promote their conservation and enhancement because the resources-protect schemes should be made to the each population unit. Mitochondrial DNA (mtDNA) has been proven effective for detecting population structure in nesting population. We use this method to assess the stock/population of green turtle ( Chelonia mydas) in the Sukamade nesting beach. Three haplotypes, i.e. C3, CS, and the new one that we called Sl were found. Haplotype (hd) and nucleotide diversities (?) were calculated to be 0.538 ± 0.115 and 0.00381, respectively. The closest genetic distance was 0.003 (between C3 and CS), and the longest was 0.011 (between C3 and Sl). Comparison between the genetic distances that found in this research and those defined for the Australasian region by Moritz et al ( 2002) is presented as a phylogenetic tree. Pairwise Fst using molecular distances following the model of Tamura-Nei for nucleotide substitution, as well as two other tests, i.e. pairwise Fst using haplotype frequencies, and the Exact test strongly indicates that the nesting population of Sukamade beach is genetically distinct as compared to the other nesting population within the Australasian region.

Abstract

Sea and coastal areas of Badung Regency, especially Kuta Political District is growing rapidly as atourism area. Increasing community activities created pollution and affected conservation areas, includeKuta Beach.This research aimed to know the positive and negative impacts of community activities of hotels,restaurants, settlement/housing, tradings and services, industries and fisherman. Besides, identificationseawater quality of Kuta Beach on their physical, chemical and microbiological parameters during rainyseasons as well as to find out effort on environment conservation done by government and local communitiesin Kuta Political District.Samples were determined using purposive sampling method collected from three locations at KutaBeach, which then analysed insite and at analytical laboratory. Seawater quality on their physical, chemicaland microbiological parameters ratio was compared with based on standard of seawater quality for marinerecreation according to Decree of the State’s Minister Environment Act Number 51 years 2004. The index ofthe population was then calculated to gain the population index. Samples of community activities werecollected using questioner, interview and observation and then analysed by qualitative description method.The result showed that activities at the sea and coastal areas of Kuta Political District had an impactsuch as increase population and job availability, provision of income to Badung Regency and TraditionVillage, environment aesthetics, perception of community, culture and region perform, waste andenvironment sanitation, land use degradation of coastal border, mobility of motorized vehicle and seawaterintrusion. The water quality of Kuta Beach during rainy seasons in February year 2006 exceeded thethreshold level or quality standard such as rubbish, NH3, NO2, NO3, PO4, Cu, Cd, Pb, E. coli and coliform.DO exceeded the minimum limits of seawater quality standard. Whereas, parameters which did not yetexceed the maximum limits namely: temperature, colour, smell, turbidity, TDS, salinity, pH, BOD, COD, fatand oil, fenol, Hg and Fe. The result showed that score of calculation pollution index of Kuta Beachseawater in three research zone, were between 6,46 and 6,77. The effort on environment conservation inKuta Political District had been conducted by local community and government, but long term effort inenvironment conservation is still needed better strategy and actions in an integrated and sustainablemanners.

Abstract

caught and consumed by local community. Monsoon is the main factor governing the characteristics of the Java Sea. This research location is in Java Sea. Chlorophyll-a and SST data will be obtained from Aqua-Modis Satellite. Wind data is `from QuikScat Satellite. Sea surface height data is from Jason 1 Satellite. Fishery data will be taken from the Fishing Port of Dadap (West Java) and Pekalongan (Central Java). Pattern of fish catching season will be analyzed using time series technique with ratio to moving average method. Effort optimum and MSY will be taken with Surplus production models by Schaefer (1957). The Total Allowed Catch is 80% x MSY. Wind direction during northwest monsoon flows southeastward and during southeast monsoon flows northwestward. Generally, wind speed and chlorophyll-a in Java Sea during southeast monsoon is relatively higher compare with it during northwest monsoon. Generally, SST and SSH in Java Sea during southeast monsoon is relatively lower compare with it during northwest monsoon. Correlation between chlorophyll-a and SST is inversely correlated with correlation coefficient - 0.578. Correlation value between wind speed and SST is -0.728. SST and SSH correlation is 0.78.During northwest monsoon, low potential area was bigger than potential area. This is cause by chlorophyll-a and low wind speed, SSH and high SST. Therefore, fish production becomes few. Potential area was located in western part of Java Sea. Meanwhile in southeast monsoon, mainly high potential area were in Bawean Island, Masalembo Island and Kangean Island. And potential area was over the Java Sea. This is cause by chlorophyll-a and high wind speed, SSH and low SST. This is indicating upwelling. So, fish production during southeast monsoon was bigger than during northwest monsoon. This match-up value between fishing ground GIS and fishing ground by fisherman is 80.2%. Catching season index shown that the increase of Indian Mackerel abundance is occurring in April and the maximum number is in July and Augustus. This is caused by the highest chlorophyll-a concentration (0.42 mg/m³) and a low SST (27-28ºC), so create a high primary productivity. This environment condition will support fish spawning. Optimum effort value is 345 vessel/month. And TAC value is 437.808 kg/month. The number of fishing vessel since 2002 increased to 2007, over optimum effort. Meanwhile, the fish production is over TAC until the end of 2004. Then it decreased under TAC to 2007. This indicates that fish catching of Indian Mackerel in Java Sea is classified over fishing. Correlation value between Indian Mackerel fish catch to ENSO in Java Sea is 0.127. This is indication of ENSO phenomena did not influence fish catching. F calculates is 6.513 with significant level 0.005. This means, chlorophyll-a and SST are together influence fish catching of Indian Mackerel in Java Sea. And correlation between fish catching with SST and chlorophyll-a is 0.57.

Abstract

Western Indonesian Sea especially Sumatra Sea, Sunda Strait, Pelabuhan Ratu Sea and Prigi Sea is a potential areafor fisheries especially tongkol. Oceanography factors that influenced to the fisheries activity are Sea SurfaceTemperature (SST), Sea Surface Height (SSH), concentration chlorophyll-a (Chl-a), monsoon and Indian Ocean Dipole.This research location is in Western Indonesian Sea. With coordinate is 97.00 E to 114.00 E, and 02.00 N to 11.00 Sin period of 2002 to 2006. Spatial and temporal analysis SSH from Jason-1 Satellite, SST and chl-a from AQUA-MODISsatellite data set used to correlation with fish production. The correlation between Dipole Mode Index (DMI) and fishproduction is use also. SST and chl-a data processing by SeaDAS software, SSH derive from website NASA, DMIderived from website NASDA. Fish production data is from statistic fish production data.The correlation value between fish production and SST in Sumatra Sea and Pelabuhanratu Sea is high with value -0.734 and -0.660. In Sunda Strait and Prigi Sea is low, with value -0.560 and -0.566. Meanwhile the correlation valuebetween fish production and chl-a in Sumatra Sea, Sunda Strait and Pelabuhanratu are high and in Prigi Sea is low. Thevalue in Sumatra Sea is 0.868, in Sunda Strait is 0.660, in Pelabuharatu Sea is 0.751 and in Prigi sea is 0.588.The fish production caught by fisherman influence by northwest monsoon (rainy season) and southeast monsoon (dryseason). Fish production will decrease in rainy season, and increase at dry season.The correlation value between fish production and DMI has a high correlation in Sumatra Sea, Sunda Strait andPelabuhanratu Sea. Meanwhile, in Prigi Sea the corelation is low. Correlation value in Sumatra Sea is 0.851, in SundaStrait is 0.656, in Pelabuhanratu Sea is 0.691 and in Prigi Sea is 0.463.
