This research is to examine the excellent commodities of fishery production, and the policies in capture fishing production in order to increase the income of fishermen. To determine the excellent commodities, the following analyses were made: (1) production continuity, average production, prices, processing and marketing, (2) Location Quotient (LQ) analysis and (3) SWOT Analysis. The results showed that of 38 species of fish that were analyzed, 31 species were of a continuous type and 7 species of non-continuous type. The average fish production is below the average production of all types of fish except for skipjack of 11,131.472 tons and flyingfish of 4405.296 tons per year. The price of beronang, kerapu, lencam, kakap and kurisi, are higher than the average price. The fish products marketed in the local market/overseas are for example kerapu, cakalang and tuna. Fish products are always marketed in fresh form. Only julungjulung fish is marketed after it is processed. Three kinds of fish are also exported, they are kerapu, cakalang and tuna. The results of LQ calculation show that there are 12 species of fish with value of LQ>1, namely: kuweh fish, kerapu, kerongkerong, teri, tembang, julung-julung, tongkol, lemadang, cakalang, mackerel tuna and cucut. Based on the scoring analysis of commodities in terms of production continuity, production, pricing, processing, and marketing associated with the value of LQ, six kinds of fishes as excellent commodities in North Halmahera Regency are cakalang, kerapu, anchovies, julung-julung, tuna, and tongkol. Flyingfish has the value of LQ <1, so it can not be recommended as an excellent fish species. Based on the results of the SWOT analysis, there are six government policies of North Halmahera Regency related to the development of capture fisheries, increasing fishing fleet is a top priority followed by the development in the processing of captured fish. Both policies are closely related to labor absorption and economic improvement.
APLIKASI METODE LOCATION QUOTIENT (LQ) DALAM PENENTUAN KOMODITAS UNGGULAN NASIONAL
Determine of agriculture superior commodities are main step to go in the direction of efficient agricultural development. There are more methods of superi or commodities identification; one is Location Quotient (LQ) approach. This paper aims to examine the implementation of LQ approach uses wide of agriculture harvesting area/cattle population series data for five years period (1997-2001) from Indonesian Statistics as main source. Data procesing conducted whith spreadsheet from Excel on Microsoft Windows XP. The results conclude that LQ method still obtained as one of relevant method for mayor agricultural commodities identification. It is suggestion for using for using LQ with supporting accuracy long series data present.
Computer simulations and theory of oceanographic fluorescence lidar signals: effect of sea surface structure.
A 3-D computer simulation model has been developed using geometrical optics suitable for analyzing the effect of sea surface structure on oceanographic fluorescence lidar signals. Depth-resolved and depth-integrated signals reveal a considerable dependence on the surface structure. The results obtained by simulation are confirmed by a theoretical approach based on the transformation of solid angles by curved boundaries. Using statistical assumptions about the distribution of curvatures of the ocean surface, a general expression for this influence is found.
