Abstract

Blood Cockle (Anadara granosa) is one type of shellfish which have an important economic value in Indonesia. Semarang waters is one of the location of the Blood Cockle which were allegedly tainted by Pb and Cd. The metal content could be reduced by depuration. This research purposed to determine the content of heavy metal concentrations in Semarang waters and determine the effect of shell length and the length of depuration time on the heavy metal concentrations of Pb and Cd in the A. granosa. This research was conducted on 23 July to 28 August 2010. The method used in this study is description on the preliminary research and laboratory experimental method for depuration. Preliminary research was performed by testing the concentration of heavy metals in water, sediments and soft tissue of A. granosa in the waters of Semarang. Primary research conducted depuration process based on differences size of the scallop shell length ≥ 2.0 cm and < 2.0 cm, and different time depuration treatment, i.e. control (without depuration), 1 day, 3 day, 5 day, and 7 days. According to AAS test results showed, the highest concentrations of Pb and Cd heavy metals in Semarang water respectively at 0.23 ppm and 0.036 ppm, in sediment 1.48 ppm and 0.091 ppm, and in the soft tissues of A. granosa of 0.82 ppm and 0.042 ppm. Depuration process can reduce the content of heavy metal concentrations of Pb and Cd, respectively at 0.37 ppm and 0.051 ppm.

Abstract

The complexity of managing export documentation and the lack of knowledge of regulations in the importing country cause non-fulfilment of requirements and cancellation of exports. This study aims to determine the stages and the mechanism for managing certificates of origin in the export process by freight forwarding or marine cargo expedition representing the exporter. The research used qualitative descriptive methods and approaches. Data was collected by observation and documentation at two marine cargo expedition companies in Semarang, Central Java, Indonesia. Data is analyzed and presented using a flowchart diagram. The results show that these companies manage COO documents through the eSKA website, with the completeness of filling in the basic information of exporters, consignees, route and transport, and supporting documents, including export declaration, packing list, invoice, goods, and cost structure. Overall, export documents are indispensable for international trade as they ensure goods' legal compliance and smooth flow across borders. The role of the freight forwarding company or marine cargo expedition in this process is to advise the exporter on the required paperwork, ensure compliance with relevant regulations, and communicate with the appropriate authorities to obtain the certificate. The positive implications of this research are that the administration of export documentation, particularly Certificates of Origin (COO) via the eSKA platform by marine cargo expeditions, enhances time efficiency for exporters and proves efficacious in ensuring the legal compliance of COO document handling. Moreover, COOs can yield favourable effects through preferential tariffs, thereby augmenting the competitiveness of exported goods.
