IDENTIFIKASI INDUSTRI BERDASARKAN LIMBAH YANG MENUNJANG PEREKONOMIAN NELAYAN NAMUN RELATIF MENURUNKAN KUALITAS AIR DAN PRODUKSI PERIKANAN
Get PDFEconomic development in DKI Jakarta is very fast, so naturally if Jakarta is Indonesia\u27s largest producer of waste, whether from domestic wastes, urban sewage and industrial waste. The purpose of this study was to identify both industrial and industrial fishing industry is relatively non-fishery will support economic and industry relative to lower fish production. In this study grouped the industry that supports the economy and industry that could cause negative impacts on marine resources (inhibiting the community\u27s economy) by using the comparative performance index. Research shows that small-scale fishing industry, medium & large are clean development mechanism (CDM), so that the relative does not pollute the environment and to support the fishing economy, but domestic scale fishing industry and retail traders often use the hazardous and toxic materials so that wastes can pollute the environment and endanger the health of those who consume. Non-fishing industries generally produce wastes hazardous and toxic materials so that tends to pollute and damage the environment. Environmental degradation resulting in decreased productivity, thereby reducing the economy of fishing communities. Order fishing industry that hamper the economy in a row is hazardous and toxic materials-producing industries have no wastewater, Producing hazardous and toxic materials Wastewater Treatment Plant do not always operate, garment, Producing hazardous and toxic materials there Wastewater Treatment Plant, Producing hazardous and toxic materials there is Wastewater Treatment Plant, there is a demand ecolabelling and Retailers & domestic fishing industry.

Get PDFIncreasing number of houses will increase in domestic waste. The high level of domestic pollution not only an impact on the waters, but also can affect the health quality of people that live along the banks of the river. The aims of this study are to determine the quality of domestic wastewater in arranged housing and the impact on river water quality. The research was conducted in August 2008 on a small scale housing Puri Nirwana Estate, Cibinong. We found domestic waste water from household activity in Puri Nirwana Estate were affecting recipient ecosystem (river). This river was polluted with indication the high value of COD, total coliform and content of detergent in the water, would endanger the health of local people who live in unplanned housing.

CONTAMINATION OF Cd AND Pb ON MILKFISH Chanos chanos CULTURED IN SERIBU ISLANDS, JAKARTA
Get PDFSeribu Islands located in the north of Jakarta Bay; it is potentially polluted by heavy metal such as Cd and Pb. The aims of this study is to prove contamination presumption, by analyzing and determine correlation Cd and Pb concentration in the sediment, in the water and on milkfish Chanos chanos cultured in this area. On this study, we collected water quality data (pH, temperature, dissolve oxygen and salinity) and heavy metals contamination (Cd and Pb) in the sediment, in the water and on milkfish. We compare collected data with quality standar and correlate heavy metal concentration between in the water and in the sediment; in the water and on milkfish organ; and, in the sediment and on milkfish organ. In general, water quality is sufficient enough to support the life of farmed milkfish. Cd and Pb contamination level in the water lied below the quality standard of Ministry of Environment decree No. 51/2004 in the last April and July. However, the contamination exceeds the standard in the last October. The contamination in sediment lied below RNO (1981), EPA (1999) and IACD/CEDA (1997). Gills, viscera and the meat of the milkfish are contaminated with Cd and Pb, yet, still lied below the quality standard of Ministry of Environment Decree No. 51/2004. The results showed that farmed milkfish in Thousand Islands are safe to eat. We also found that the correlation of Cd and Pb contamination between water and sediment is positive. The correlation of Cd is much higher than Pb. The correlation of Cd between water and viscera as well as between sediment and viscera are the most closely related than any other organ. Keywords: contamination, Cd, farming, milkfish, Pb, Seribu Islands</jats:p
Study of Heavy Metal Distribution and Hydrodynamic Simulation in Green Mussel Culture Net, Cilincing Water - Jakarta Bay
Get PDFThis study aimed to investigate the heavy metals distribution in the surrounding area of green mussel culture net, Cilincing water, Jakarta Bay, and its distribution behavior. The water sampling was carried out during the ebb tide. The heavy metal concentration was then measured by using atomic absorption spectroscopy (AAS). In order to understand the water circulation behavior related to heavy metal distribution in the study area, the Princeton Ocean Model was applied, and the model design was developed based on a scenario of an open canal in the eastern and western sides, while the center canal was placed with net cages in the water column resembling the green mussel culture net. The
observed heavy metal distribution showed an intensified concentration in the green mussel culture location. The observed water current also showed a reduced velocity in the location. The modeling approach could explain the water circulation behavior in response to the presence of net units in the water column. In this case, the density of net units for green mussel culture potentially produced shear stress in the water column, which affected the flow pattern and the distribution of heavy metals. Therefore, the existence of green mussel culture nets has a potential to become a trap for pollutant distribution in the water
Bioaccumulation of Cadmium and Lead in Prickly Pen Shell in Seribu Archipelago
Get PDFJakarta Bay waters contaminated with heavy metals, so that the waters of the Thousand Islands are also potentially contaminated with heavy metals. The purpose of this study were to determine the condition of the water quality on the Panggang Island and Karya Island, analyze contamination of heavy metals (Cadmium and Lead) in water, sediments and Prickly Pen Shell and then the correlation. Based on Ministry of Environment decree No. 51/2004, water quality in the Panggang Island and Karya Island tend toward to low category. Cadmium and lead concentration in the water on October exceed the quality standards. In the sediment on July and October at Karya Island, concentration of cadmium were exceed the quality standar by RNO. On the other hand, cadmium and lead concentration on Prickly Pen Shell still below standard quality from decree of Director General of POM RI No. 03725. We found highest positive correlation were found between cadmium and lead accumulation in the water and on the Prickly Pen Shell, then positive correlation between cadmium and lead in the water and in the sediment. For the heavy metal contamination, we found contamination of cadmium correlation were higher than lead contamination.</jats:p
A preliminary investigation of associated chemicals in cigarette butt waste from the tourist beach area of North Jakarta, Indonesia
No full textCigarette butts are among the most common and problematic forms of marine litter. However, there is limited research on the occurrence, abundance, and potential chemicals associated with cigarette butt waste in the environment. The study focused on investigating the occurrence, abundance, and chemical composition of cigarette butt waste on Ancol Beach, Jakarta, Indonesia, addressing a gap in knowledge regarding this prevalent and problematic form of marine litter. Despite Ancol Beach’s regular cleaning efforts, cigarette butt waste was still widespread with an abundance of 1.136 pcs/m2. However, this cigarette butt waste number is still less abundant compared to other regions. Chemical analysis of the cigarette butt waste revealed the presence of various chemical groups, notably aliphatic hydrocarbon compounds. The study emphasizes the importance of understanding and mitigating the environmental repercussions of the chemicals associated with cigarette butt waste and microplastic particles on the coastal ecosystem. Further research is urged to delve deeper into the emerging chemical pollutants present in cigarette butt waste spread in the coastal environments
MICROPLASTIC IN THE DEEP-SEA SEDIMENT OF SOUTHWESTERN SUMATRAN WATERS
No full textIndonesia was recently ranked second on the list of countries producing plastic waste. Plastic can be degraded by thermal oxidation either with ultraviolet radiation and by mechanical to a very small size the size will be smaller. Degraded plastic with small sizes (<5 mm) measured has been micrometers known as microplastic. We took sediment samples on 07-18 May 2015 in EWIN 2015 cruise, which part of the contribution of Indonesian researchers for the International Indian Ocean Expedition-2 program, at 66.8 to 2182 m below sea level. Microplastic analysis from the sediment was carried out by using flotation methods. We found microplastic in 8 locations out of 10 sampling locations. We found 41 particles microplastic with a form of granules (35 particles) and fibers (6 particles). Most of microplastic particles were found at depths less than 500 m with 20 particles. The discovery of microplastic in the sediment from the sea of western Sumatra at a depth more than 2000 m, indicated that plastic, considered new developed materials (early nineteen centuries made), has invaded marine areas, including pristine areas. It confirms the statement that plastic waste has spread widely to different areas of the seas and oceans, including remote and mostly unknown areas such as the deep sea
