Abstract

parts of sampling areas: Sanur Kaja 5-6 meter (SA2) and 7-8 meter (SA3), Kelurahan Sanur 3-4 meter(SB1) and 5-6 meter (SB2), Sanur Kauh 3-4 meter (SC1) and 5-6 meter (SC2), using Cluster RandomSampling method.The result in April showed that from 14 parameters examined only 5 parameters have highconcentration than the acceptable drinking water standard (PPRI no.82, 2001). Those parameters areDissolved Oxygen (DO), Biochemical Oxygen Demand (BOD5), Nitrate (NO3), Phosphate (PO4), and TotalColi form. While the result of the analyses in June showed that 9 from 14 parameters have highconcentration than the acceptable drinking water standard ( PPRI no 82, 2001) they are Total DissolvedSolid (TDS), Dissolved Oxygen (DO), Biochemical Oxygen Demand (BOD5), Nitrate (NO3), Nitrite (NO2),Ammonia (NH3), Phosphate (PO4), E. coli and Total Coli form.The increasing concentrations indicate some pollution has occurred in these sampling areas. Theobservation has shown that most of the people in Sanur dump their waste water into the ground, which easilyabsorb through the porous soil then contaminate the ground water aquifer. Based on the water quality status using the pollution index, almost all the sampling areas have low pollution index, except the one at SanurKaja 7-8 m (SA3) has moderate pollution index.

Abstract

A study on mollusks (Amphidromus peversus) has been carried out on Udayana University, BukitJimbaran (Bali, Indonesia) campus between November, 2003- November, 2005. The study was undertakenon a secondary forest on a limestone dry soil with dominant vegetation of Glerecydium sepium, Lantanacamara, Ceiba pentranda, and Acasia auriculiformis. Samples were randomly taken on quadrate samplings.Mollusks were captured on the land surface or on living vegetations. Results of the study showed that A.peversus has an average of shell length of 27.9 mm, shell width 18.0 mm , and body weight 7.90 g, number ofshell whorls 5.3, with the proportion of direction of whorl to the right of 55.3%. The shell of A. peversus hasno operculum. The color of the shell was yellow with brown stripes.The relationship between shell length (X) and with body weight (Y) can be represented by theequation of Y = 0.473 X – 5.32 (R2 = 11.9 %), which showed week relationships between those parameters.Meanwhile the relationships between the shell length (X1), width (X2) and body weight (Y) was best fitted bythe following equation : Y = 0.289 X1 + 0.0140 X2 – 3.47 (R2 = 94.9%).

Abstract

Sekonyer river as west border of Tanjung Puting National Park, is the main flora and fauna preservation areasespecially for orangutan conservation. Part of Sekonyer river upper course around year 1990 to 2002, there was anillegal gold mining (IGM) activity, and in 2002 this IGM was forbidden to be operated because of the use of mercuryfor extracting the gold. In former IGM location, up to this research has been done, the location is still used for silikapuya (sand) mining that is extracted from the sands by using water from the river, as a result, the waste water wasinundated in the mining area and flows into Sekonyer river. The objectives of this research are first of all, to identifythe heavy metal degree of the water, such as mercury, copper, cadmium, zinc, lead, arsenic, and chrome. The secondone is to identify the source of pollution, and the last one is to identify the potential heavy metal that pollute the water.Composite method was used in collecting the water samples, i.e. in Sekonyer river and the mining location.Water and puya samples were analyzed in Analytical Laboratory of University of Udayana, and then its pollutionindexes were counted, and the quality of the water was fixed based on Third Degree of quality standardized criteria,Government Rule Number 82 Year 2001.The results of the research show that along the Sekonyer river, from upper to lower courses of the river sideswith the following conditions: from the lower course of mining area it was found light pollution with pollution index of 2,51, after puya mine it was found heavy pollution with pollution index of 17,84, up to mid of Rimba Orangutan Eco-Lodge with Sekonyer river estuary there were found light pollution with pollution indexes of 3,71; 4,59; and 2,88respectively, but in the junction of Sekonyer river and Ulin river it was found moderate pollution with pollution indexof 5,13, and in Sekonyer river estuary it was found heavy pollution with pollution index of 16,35.It was also found heavy pollution with pollution index of 16,26 in the inundated water in the puya mininglocation . It was also happened to puya in the mining location that was contaminated by heavy metal of mercury in0,1168 ppm and zinc in 0,195 ppm degrees, whilst in Kumai river, upper side of Kumai quay it was found heavypollution with pollution index of 17,42.From the results of the analysis, it can be concluded that the heavy metals was derived from mining area(Aspai), from the sea and also from upper course of Kumai river. The potential metals as the pollutant were cadmium,zinc, lead, and mercury.

Abstract

Oily waste can pollute environment. One of the method used to process the oily waste is aerationmethod. This researce is carried out by taking oily waste PT. Indonesia Power Business Unit Electric PowerStation Bali at Pasanggaran Denpasar, aimed at increase quality of the waste.The sampel used is waste of PT. Indonesia Power Electric Power Station Business Unit of Bali. Thesampel is intercepted and retained in a retaining box, and 11,12 litters are then taken to be put intotreatment tank. Aeration treatment duration given varies, such as 12 hours, 24 hours, 48 hours, and 72 hoursfor the sampel with air flow speed of 0,6m/s. The treatment is also done with adding sampel with mud of 1%of the whole sampel volume. The relation between Aerating duration with oil contents, oil layer, BOD value,COD value, TDS value and TSS value will be analyzed with simple correlation and descriptive analysis.Aeration treatment can reduce the contents of oil in waste and separate oil accumulated in the waterso that the oil can be depressed up. Aeration treatment can also lower BOD value, COD value, TDS valueand TSS value because giving oxygen in to waste will meet the needs of oxygen of disentanglingmicroorganism in the waste water and the needs of oxygen for oxidation of chemicals in the waste.Therefore, aeration treatment can increase quality of the waste.

Abstract

Natural conservation management is a very important task that not only aims to save the environment but alsosupport the people that live in it. All variables of life become part of the management goal which often blurs the phasesof management processes towards an effective one. This study aims to measure the effectiveness of conservationmanagement of West Bali National Park (TNBB) based on measured indicators.The methods of measuring effectiveness is based on several indicators (biophysical, socio-economics andgovernance) using the LIT (Line Intercept Transec) method to monitor coral reefs on 8 diving sites in TNBB. Thesocio-economics and governance indicator utilize questionnaire method and discussions with a sample of localcommunity selected randomly from 4 villages around the TNBB zone.The biophysical indicator demonstrate that the amount of coral reef cover in TNBB is 37,1% which falls underthe MEDIUM category. Meanwhile, the socio-economic indicator illustrates that the community relies very little onmarine resources and have an adequate understanding of conservation efforts and sustainable use of naturalresources. Governance indicator shows that stakeholders involvement is proceeding well with a good level ofsatisfaction regarding collaborative management process.Collaborative management of TNBB waters is quite effective in conserving coral reef ecosystem, which is builtfrom awareness, ownership and stakeholder commitment through a cooperation of various organizations called ForumKomunikasi Masyarakat Peduli Pesisir (FKMPP).

Abstract

The research used 51 tissue samples taken from 51 individual Green Turtles in Pulau Panjang, EastKalimantan. The isolation of mtDNA was achieved by adding Proteinase K into the samples prior to the utilization ofthe PCR (Polimerase Chain Reaction) technique. The MEGA 3.1 computer program was employed to read the DNAsequences obtained through the PCR technique.Seven different haplotypes were identified from the analyzed samples. The haplotypes are: A3 (N=7; 13.73%),A4 (N=1; 1.96%), A6 (N=2; 3.92%), C3 (N=5; 9.80%), C5 (N=6; 11.76%), C14 (N=5; 9.80%) dan D2 (N=25;49.02%). Tag findings clearly demonstrated that the Green Turtles, which feed on the seagrass beds of Pulau Panjang,originated in different nesting sites, including Sabah and Trengganu in Malaysia, Sangalaki and Derawan inIndonesia, and Phillipine. The MSA (Mixed Stock Analysis) showed that the Green Turtles population in PulauPanjang was composed of several management units (nesting sites), which were Berau (47%), Sulu Sea (34%) andMicronesia (6%).
