Abstract

Trace metal contamination of marine environments can be determined by measuring trace metalconcentration in sediments, water or biota. Biomonitor organisms have the advantages over othermeasurements that they concentrate the portion of metals that are in a biologically available form, and thisportion which is usually of interest when assessments is being made of trace metal contamination.Correspondingly, whole tissue trace metal concentrations of 4 metals in common Jakarta Bay benthic species(polychaetes, molluscs, crustaceans) from contaminated locations were measured. The mean concentrationfor Cu was 17.5 ± 21.8 μg g-1 dw in polychaetes, 11.9 ± 8.8 μg g-1 dw in molluscs, and 12.2 ± 5.5 μg g-1 dw incrustaceans. The mean concentration for Cr was 172.8 ± 262.5 μg g-1 dw in polychaetes, 31.8 ± 62.8 μg g-1dw in molluscs, and 28.5 ± 29.0 μg g-1 dw in crustaceans. The mean concentration for Zn was 152.4 ± 76.4μg g-1 dw in polychaetes, 132.0 ± 106.3 μg g-1 dw in molluscs, and 515.8 ± 503.5 μg g-1 dw in crustaceans.The mean concentration for Pb was 6.3 ± 13.6 μg g-1 dw in polychaetes and was 2.0 ± 4.5 μg g-1 dw inmolluscs. The study provides significant contribution to confirm the content of heavy metal in each commonbenthic species inhabits coastal Jakarta Bay.

Abstract

Alteration of land is continuing to increase inorganic matter to marine ecosystems and reduce marine biodiversity. Therefore, we investigated the interplay among land use and heavy metal (Cr, Cu, Pb, Zn) inputs from 8 rivers of Jakarta Bay to the benthic biodiversity. At current time, land uses surrounding Jakarta Bay are fulfilled with industrial activity, settlement, and agriculture. Total concentration of Cr, Cu, Pb, and Zn were determined using the Atomic Absorption Spectrometry in order to assess and compare contamination levels among land use types. Results showed that the average concentrations of heavy metals in sediment were generally higher in river-mouth received water from industrial than those in agriculture. Those land use related metal pattern were also reflected in the benthos diversity. Macrobenthic community diversity decreased when inputs of organic matter increased. Decreases in macrobenthic diversity were mainly linked to an increasing abundance of species with specific functional traits, specifically deposit–feeding polychaetes. Our finding confirmed that land use in the form of industrial areas were potential to produce toxic material to ecosystems. Therefore, we recommend that the development need to consider the allocation of physical infrastructure particularly near waterways.

Abstract

Nurse migration among G20 countries increased as consequence of shortage of nurses in developed country members. Concrete strategies needed to address the issues. This study aimed to propose policy recommendation to the G20 Forum to enhance nurse migration system and long-term solution for shortages of nurses. A qualitative study was conducted to collect ideas for policy recommendation through experts sharing and focus group discussion. 190 participants involved. A descriptive qualitative approach was used to analyze the data. A policy recommendation was formulated into four themes and 11 categories. The themes included (a) harmonization for equal nursing competency qualifications, (b) reinforcement of brain drain anticipation and brain gain support, (c) improvement of regulatory and data system for nurse migration, and (d) collaboration enhancement with stakeholders for an enabling environment. The formulated policy recommendation may be used as a reference for current G20 leaders to create more concrete strategies for enhancing nurse migration system and long-term solution of shortages of nurses, as part of commitment on the health agenda. Considering the finding of this study highlighted the role of NNAs and NSAs for collaboration enhancement with stakeholders for enabling environment, we suggest a further study to identify more detail strategies to enhance NNAs and NSAs’ role in enhancing registration, placement, and monitoring processes.
