Abstract

This reseacrh aim to explain about the eefect of the implementation of ASEAN - China Free Trade Area (ACFTA) on the development of Crude Palm Oil (CPO) export from Indonesia to Tiongkok. ACFTA is an agreemnet between the members of ASEAN and Tiongkok to make free trade. This research uses the qualitative descriptive as the method and secondary is the techniques of collection data. Futhermore author uses the librarism perspective with nation state as the level of analysis and uses the international trade with competitive advantage theories by David Ricardo. The result of this research shoe the export of Indonesian’s Crude Palm Oil (CPO) to Tiongkok having an increase since was implementated of ASEAN –China Free Trade Area in 2010, and the production of Indonesian’s Crude Palm Oil increased after the ASEAN – China Free Trade Agreement appliedKey Words: Export, Crude Palm Oil, ASEAN- China Free Trade Area, Bilateral relation, Free Trade Area.

Abstract

Lipase catalyses hydrolysis and esterification of lipids. The purpose of this research was to  obtain lipase producing indigenous fungi, to identify the selected fungi, to study optimum temperature and pH of the enzyme activity, as well as the  enzyme ability in interesterification reaction. The isolates used in the experiment were isolated from tempeh, oncom and BPPT laboratory culture collection. The results showed that three fungal isolates which isolated, tempe and oncom and  an isolate of BPPT-CC were positive produced lipase after qualitative assay using Rhodamine B, olive oil and PVA. The morphology identification of the isolates, revealed that R isolate was  Aspergillus sp, T isolate was Neurospora sp. and O isolate was Rhizopus sp. Upon quantitative assay from determination of the media and time production, potato dextro broth (PDB) with olive oil 2% in 48 hours fermentation showed the highest specific activity of the enzymes. Lipase produced from three isolate have the optimum at pH 4, temperatures at 40-45 °C and stable in interesterification reaction (55 °C) for 30-40 min. HPLC analysis after interesterification enzymatic reaction in mixture palm kernel olein (PKOo) and palm stearin (POs) showed that the composition of triglycerides (TAG) do not change if compared with the commercial lipase (Lypozyme TL1M).
