2-Acetyl-1-pyrroline (2-AP) is the most important compound in aromatic rice that correlated with the quality of the aroma, therefore, determination of 2-AP concentration become very important. This research aims to find the extraction method to obtain the highest yield recovery of 2-AP. The materials used were H51 and Segara Anak to treatments test, and Pandan wangi, Sariwangi, Sintanur, and Gilirang for comparison the methods. Analysis using SPME method with three types of sample treatment, i.e. 80 mesh flour, 45 mesh flour, and cooked rice. While the analysis using Likens Nickerson with a different anti-foaming agent (MgSO4 and silicon) and a different ratio of rice and water (1:2 and 1:3). Extract samples were analyzed using Gas Chromatography Mass spectrometry (GCMS). The best results of any treatment will be used in a comparison test between the two extraction methods. The sample type of 45 mesh powder on SPME method (SPME-opt) and silicon as an anti foaming agent as well as rice and water ratio 1:3 on the Likens Nickerson method (Likens Nickerson-opt) is the best treatment in determining the yield recovery of 2 - AP. Comparison test indicated that SPME-opt is better than Likens Nickerson-opt in obtain the yield recovery of 2-AP.

Publisher : Pusbindiklat - LIPI

Fishermen exchange rate (NTN) is one of the tools or indicator to see the welfare of fishing communities. This paper aims to analyze the structure of received value index, paid value index and dynamic of NTN. This study uses a quantitative approach through surveys. The study was conducted in the Batu Lubang Village, South LembehDistrict, Bitung City, North Sulawesi Province in 2012. 31 respondents determinent by purposive sampling. This research using value index as a NTN instrument, is the ratio between fishermen received value index (It) with the fishermen paid value index (Ib). The results showed that received value index is strongly influenced by theproduction and price of tuna catch. Paid value index is strongly influenced by the variable cost of fishing. Fishermen exchange rate index experienced a downward trend so that it can be said that the welfare of fishermen also decreased.
