ABSTRACT
Sea grape is a kind of potential seaweeds which is rich of secondary metabolites. Glycoglycerolipid and enol groups are metabolites produced from Caulerpa racemosa. In addition, the diterpenoid compounds, triteipenoids, nitrogen components and caulerpenyne (CYN) are major metabolites of Caulerpa species. Caulerpa racemosa is a source of antioxidants, antimicrobials, cytotoxins, antidiabetic, antimociceptive, and anti inflammatory. This species is also potential as a source of medicinal agents and functional food applications as well ...

ABSTRACT
Indicator organisms are used to measure potential fecal contamination of environmental samples. The presence of coliform bacteria, such as Escherichia coli, in surface water is a common indicator of fecal contamination. Caliform bacteria in water samples may be quantified using the most probable number (AFN) method, a probabilistic test which assumes cultivable bacteria meet certain growth and biochemical criteria. If preliminary tests suggest that coliform bacteria are present at numbers in excess of an established ...

Designing research activities prior to implementation is important. Design activities include preparation before, while and after study. Preparation before the survey is to prepare administrative, create a map of the sampling location in the held and to prepare equipment to be used in field work. In the field work, noting the position of sampling location, taking samples and making descriptions of the environment around the area of research. Processes in the laboratory including analyzing the ...

ABSTRACT
The quantitative method for ranking and scaling of biostratigraphic events has been being developed during the past 30 years. The purpose is to combine biostratigraphic dataform exploratory wells drilled in sedimentary basins to construct a regional biozonation that can be used for correlation between sections within a study area. Ranking is illustrated by application to a simple, artificial dataset. Scaling is explained as a refinement of ranking. Implications of sampling of stratigraphic sections are discussed ...

ABSTRACT
Contamination in Indonesian waters needs to be continuously monitored to prevent serious damage an ecosystem. Environmental monitoring involves not only contamination analyses in water; sediment and organisms but also application in ecotoxicological approach to detect contaminant effects to organism. Selection for bioindicator must consider many factors including abundance, easy to handling, taxonomy is well known, sensitivity and ecological relevance. Java merdeka (Oryzias avanicus meets that requirements and potentially to develop as bioindicator for environmental monitoring ...
