Abstract

Regional Ocean Modelling System (ROMS) has been intended to be a multi-purpose, multi-disciplinary oceanic modeling tool. The Biogeochemical model have coupled to ROMS consists of a system of seven coupled partial differential equations that include: nitrate, ammonium, small and large detritus, phytoplanJ..'ton, zooplankton, and a dynamic phytoplanJ..-ton carbon to chlorophyll ratio. The study of distribution patterns of chlorophyll-a in Lombok Strait (-7 °N - ·10 •sand 114 "E - 117 °E) in 2006 was analyzed using the Biogeochemical model based on ROMS. The results show that low chlorophyll-a distributions (0.20 mgChl-a/m3) observed in Lombok Strait in ,January. Chlorophyll-a estimated around the southern part of Bali Strait and low chlorophyll-a distribution in upper layer of the Lomhok Strait. Chlorophyll-a of the booming (0.32 mgChl-a/m3) observed in August. The northeast current direction moves to the west and southern part of research area through Lombok Strait. The highest chlorophyll-a concentration estimated in the northern and southwestern part of Bali Tsland and also in the southern part of Lombok Island. During dry monsoon, southeasterly wind blow from Australia generates upwelling process (low temperature and nutrient-rich water near the surface) also estimated from ROMS.

Abstract

Prof. Ir. Herman Johannes Forest Park has suffered a serious damage from illegal logging and other destructives activities. This condition is worsened by lack of law enforcement and awareness on the importance of forest for the community. This study aims to determine level of damage from illegal logging, and formulate strategies to sustainably manageon the Prof. Ir. Herman Johannes Forest Park. Public perception was obtained by administering questionnaires and interviews through a purposive sampling method. The level of damage from illegal logging was assessed through identificationand measurement of damaged locations.SWOT analysis was used to formulate the management strategiesbased on identification of internal and external factors. Findings revealed that 5% of Prof. Ir. Herman Johannes Forest Park were damaged caused by illegal logging. The management of the Forest Park was challenged by illegal logging, forest encroachment, timber extraction for household use, slashing and burning practices, poor spatial planning, ineffective institutional arrangement, wildlife poaching, illegal grazing,and inadequate facilitates and staffs capability. In addition, there was lack of community involvement in the forest management. Aspects that appeared to require the most attention to improve the Forest Park includes consolidation of status and functions of the Forest Park, enhancement of surveillance and enforcement, improvement of the management effectiveness by establishing special division to manage the Forest Park, improvement of staffs capacity and infrastructures, rehabilitation of the damaged area, improvement of awareness to the impact of deforestation, and involvement ofindigenous and local communities on the Forest Park management (i.e. community-based forest monitoring, application of local wisdom in the forest management, community empowerment and economic development).

Abstract

CFC refrigerant has been known to be one of causes of ozone layer diminishing and HFC is one of green house gases contributing to global warming through the leak and synthetic refrigerant waste to environment. As a response to the ozone layer diminishment on stratosphere, UNEP, in 1981, through a negotiating process of international stages of development reserve the ozone layer through Wina Convention legalized in March 1985. It was then followed up with Montreal Protocol in September 1987 consisting supervision rules on producing, consuming, and treading ozone damaging materials. The government of Indonesia had ratified the convention through President Decree Number 23 Year 1999. The ozone layer reservation program implementation in Indonesia is facilitated by KLH. Governor of Bali issued Decree Number 523/04-B/HK/2010 on membership restructuring of ozone layer reservation and ozone damaging materials control team work in province of Bali. This research was done in 27 car AC service companies or workshop, which received grant of 3R engine in Denpasar, Bali. The research was dominantly focused on monitoring and evaluation, that is how car AC service company or workshop manage CFC/ R-12 and HFC/R-134a refrigerant at service time using 3R engine that refrigerant does not escape to atmostphere. Cooling machine work procedure test (COP) was conducted in laboratory. Research result showed that car AC service company or workshop could manage CFC/ R-12 and HFC /R-l 34a eefctively ( 88,3%). The cooling engine work procedure using CFC /R-12 as the result of 3R engine recovery and recycel resulted in 2,435 while pure CFC/R-12 resulted in 2,54. There were differences in cooling engine work procedure to the use of pure CFC/R-12 refrigerant with that resulted by 3R engine with avarage difference 0,089 or 3,53%.

Abstract

Research of bioaccumulation of Pb and Cr in vertical biofiltration systems with bacterial inoculum derived from aquatic sediments South Denpasar aims to get the best sediment sources that can be used as an active suspension to process metals Pb and Cr dissolved. Sediment samples taken from some waters are ecosystems Mangrove Statue Ngurah Rai Tuban, Benoa Harbour and Estuary Dam Suwung. Each sediment samples were grown in a liquid medium to get the best active suspension, which was determined by an increase in biomass ( VSS ) and the speed of growth. Best active suspension is used as inoculum in the vertical biofilters to decreaseconcentration of Pb and Cr dissolved. Ability of vertical biofilter is determined by their effectiveness in lowering levels of Pb and Cr and capacity of the system used. The results showed that the vertical biofiltration system capable of lowering the concentration of Pb and Cr to each concentration became 0.1680 ppm and 0.1460 ppm within 6 hours of treatment with initial concentration of 2 ppm respectively. The results showed that the vertical biofiltration system capable of decreasing the concentration of Pb and Cr became 0.1680 ppm and 0.1460 ppm within 6 hours of treatment with initial concentration of 2 ppm respectively. This concentration has been below the qualitystandard (PerGub Bali No.8 Tahun 2007). The highest effectiveness of vertical biofilters system against Pb and Cr occurred while processing time of 24 hours with the respective value amounted to 99.49 % and 99.41 %. While the value of biofiltration capacity in lowering the concentration of Pb and Cr amounting 4,3188x10-3 mg/g and 4,5369x10-3 mg/g. In microbiological tests, one type of bacteria that play a role in the process of bioaccumulation of Pb and Cr is Bacillus sp in the amount of 20 CFU/g.

Abstract

Land resource damage caused by the land conversion and land use without regard to principles of conservation of soil and water. The damage resulted in the erosion is very high. Changes in land use without regard to principles of conservation of soil and water is currently happening in Baturiti District. Given this research can determine the level of erosion, soil and water conservation planning, land capability classification and proposed land use in Baturiti District. Erosion prediction using USLE (Universal Soil Loss Equation) to estimate the rate of erosion and also to get an idea the determination of soil and water conservation measures appropriate to the region. Determination of the land capability classification method Arsyad (1989) is by classifying land capability to classify land capability class based on the value of the limiting factor of land that is adjusted with land capability classification criteria. Determining of the proposed land use using the scoring method by combining the slope factor of the field, the soil sensitivity of the against erosion and the intensity of daily rainfall. Soil sampling is done by taking a total of 19 soil samples from a unit of land. The prediction results on each unit of land erosion in the area showed the level of erosion is very light covering an area of 11,70 ha, mild erosion area of 5.221,56 ha, erosion was an area of 88,10 ha, severe erosion area of 616.20 ha and very severe erosion area of 2.195,39 ha. Soil and water conservation measures required on land units with erosion prediction value exceeds the value erosion that can be tolerated so that the value could be below the value erosion erosion can be tolerated. Capability classification of the land in the study area consists of land capability class II with an area of 1489,39 ha, class III area of 827,39 ha, class IV with an area of 830.15 ha, class VI area of 1.373,79 ha, class VII covering 1.453,92 ha, class VIII covering an area of 2.176,31 ha. Tutorial use of land for the forest department is directed to the protected forest area covering an area of 2.458,00 ha. Tutorial use of land outside the forest area to protected area 1079.81 ha (13,27%), a buffer zone covering an area of 1.662,31 ha, annual crop cultivation area covering an area of 844.86 ha and seasonal crops cultivation area covering an area of 2.087,97 ha.

Abstract

The dyeing business potentially leads to pollution. This study aims at exploring to what extent the dyeing business adhered to 1) the permits required; 2) the system of how the waste produced should be processed; 3) awareness of dyeing companies owners on the environment. The research was conducted by observing and interviewing the owner. Two criteria were referred to in this study; criteria 1 was scored S (good) and criteria 2 was scored 1 (bad). Each component was scored depending on environmental priorities determined. The waste was tested to determine the criteria of pollution and envirovmental damage. The parameters of the waste water tested were BODS' COD, TSS, Sulfide, Phenol, Mineral Oil and Chromium (Cr). The research findings showed that ( 1) the owner did not have the standardization of permit; ( 2) the wrongly applied method turned out to disturb the expected process and was not in accordance with the criteria how the dyeing waste should be processed which was responsible for the fact that there were four chemical parameters which exceed the Standard Waste Water Of Textile Industry such as BOD 5, COD, TSS and Sulfide; ( 3) the dyeing business did not pay any attention to environment; nothing was done to contribute to environmental preser vation. Conclusion of this research is the dyeing business is not required with the three variable was be depending.
