Abstract

Anthropogenic pollution (organic matter and Hg) around Cisadane River upstream can affect the abundances of macrozoobenthos. The aim of this research was to identify the abundances of macrozoobenthos and feeding groups, and also to identify the status of waters based on macrozoobenthos community. The research was conducted on January to March in four locations in the upstream of Cisadane River, covering Cikuluwung (ST 1), Cisarua (ST 2), Curug Bitung (ST 3), and Lukut (ST 4). Samples were collected with kick net and Eckman Grab. The dominance macrozoobenthos are Bungona (171 ind/m2), Simulium (101 ind/m2), Cheumatopsyche (50 ind/m2), and Polypedilum (28 ind/m2). Based on feeding groups, the dominance are filtering collector and gatherer collector. Based on the Pollution Index and Heavy Metal Pollution Index (Hg) on sediment, the upstream of Cisadane River is low polluted whereas EPT Index and Signal showed that upstream of Cisadane River is moderate polluted.

Abstract

The research on horizontal distribution clorophyll-a fitoplankton as indicator the tropic state in waters of Meulaboh Bay conducted on Mei-July 2014 in Meulaboh Bay. Sampling was done using the method of purposive sampling at 10 sites, which consist of river, mouth river, bay waters, and middle of bay to outer of bay. The purpose of this research is to analyse horizontal distribution of clorophyll-a fitoplankton as the tropic state indicator in the waters and to analyse relationship between clorphyll-a fitoplankton with nutrients availability N and P. The result showed that the horizontal distribution pattern of clorophyll-a fitoplankton dominated by the waters near to teresterial land, likes river, mouth river, and edge of bay, afterward its gradually slightly decrease in the middle of bay and lower in outer of bay. High or low of clorophyll-a was due to the influence of nutirent load N and P in the waters of Meulaboh Bay. The tropic states based on abundance clorophyll-a fitoplankton was categorised in the mesotrofic condition.

Abstract

Jakarta Bay is one of the aquatic ecosystems with the highest level of organic pollution in the world. Ecological condition of Jakarta Bay’s water will affect the ecosystem, including the distribution of heterotrophic bacteria. This study aims to determine the dynamics of the distribution of heterotrophic bacteria in the Jakarta Bay. Sampling was done by 4 repetitions during the year of 2013. Primary and secondary data was used in this research. The results showed an abundance of heterotrophic bacteria fluctuate and are relatively high in the area close to the mouth of the river and decreasing abundance in the ocean. The highest abundance obtained at Station 10 with 3,5 × 106 CFU/ml density and the lowest abundance obtained at Station 1 with 1,8 × 105 CFU/ml density. The highest density obtained in October with an average of 1,3 × 106 CFU/ml and the lowest density obtained in July with the average of 3,5 x 105 CFU/ml. Abundance of heterotrophic bacteria have a close relationship with chlorophyll-a

Abstract

Mangrove ecosystem services, aside for the fisheries sector, also have ecosystem services in mitigating climate change as carbon sinks and storage. Musi river estuary located in Banyuasin Regency, South Sumatra has the potential of mangrove forests as carbon reserves. The purpose of the study is to analyze the community structure, potential carbon stocks, and economic value of mangroves in the Musi River Estuary. Data were collected at five stations using the 100 m quadratic transect method vertically to the coastline. Data analysis was conducted based on the allometric equation for biomass information, carbon storage, and the economic value of carbon stores. Mangrove ecosystems in the Musi River estuary are Sonneratia alba, Nypa fruticans, Sonneratia casiolaris, and Rhizopora apiculata. Mangrove species that have important roles in the sustainability of ecosystems are Nypa fruticans and Sonneratia alba each with IVI of 145.6 and 101.28, respectively. Carbon storage of mangrove in the Musi river estuary is 107.34 tonC / ha and carbon dioxide absorption is 393.59 tCO2 / ha with a mangrove area of ± 5276 ha. The total estimated economic value of carbon generated from mangrove are Rp174.441.016.895 (free market) and Rp455.872.524.151 (CDM). Keywords: carbon, mangrove, Musi river estuary
