Abstract

Tujuan pembangunan perikanan adalah pemanfaatan sumberdaya perikanan untuk kesejahteraan dan kemakmuran rakyat banyak. Dalam pelaksanaannya tujuan pembangunan perikanan tersebut dijabarkan dalam beberapa sasaran yang slfatnya bertentangan, sehingga sulit untuk mencapai seluruh sasaran tersebut secara bersamaan. Pemerintah harus memberikan suatu prioritas pembangunan penkanan yang didasarkan pada ketersediaan sumberdaya, teknologl, pendanaan, ekonomi politik dan faktor-faktor kendala yang dihadapi. Pembangunan perikanan selama 1980-1985 yang dipengaruhi oleh kebijakan periode sebelumnya nampak adanya kecenderungan beroroentasi pada pertumbuhan produksi dan ekspor serta kurang memberikan perhatian yang memadai pada aspek keberlanjutan dan pemerataan sosial dari hasil pembangunan perikanan.

Abstract

The mangrove conversion become fish pond, bareland or others has an impact in water quality. One of water quality parameter is Total Suspended Solid (TSS), increasing TSS means the rising in pollution.  Landsat remote sensing data with multi channels used in studying the dynamic of mangrove – fishpond change and TSS along the Berau waters. Several regions with its variation are used in that dynamic studying.  The TSS algorithm for Berau waters is TSS (mg/l) = 3.3238 * exp (34.099*Red Band) , Red band=the atmospheric reflectance band 2 validated with field data. The result study is the conversion of mangrove become fish pond has the strong indication in the rising TSS .

Abstract

Free cash flow is viewed as performance parameter that’s more promising because it’s more transparent in presenting operational activity, investment, and company’s funding. Besides those advantages, there are two questions: (1) is the free cash flow able to become determinant against stockholders’ value and (2) are there other factors which affect it? This study took sample from 184 non-finance companies registered at Indonesia Stock Exchange period 2003 – 2010, using double regression analysis method. The result of this study shows that negative free cash flow, dividend, and leverage has significant influence against stockholders’ value.

Abstract

Total suspended solid (TSS) is one of the water quality parameters and limiting factor affecting coral reef growth. In this study, we used the algorithm of TSS= 3.3238*e(34.099* Green band) (where green band is reflectance band 2) to extract TSS from Landsat satellite data. The algorithm was validated with field data. Water column correction method developed by Lyzenga was used to map coral reef. The result showed that the coral reef area in Berau waters decreased significantly (about 12,805 ha or around 36 % ) from the year of 1979 to 2002. The most coral reef reduced area was detected around Derawan Island (about 5,685 ha). Further, some areas changed into sand dune. TSS concentration around Delta Berau and Derawan Island increased aproximately twice from 15- 35 mg/l in 1979 to 20-65 mg/l in 2002. The increase of TSS concentration was followed by the decrease of coral reef area.

Abstract: Producing shrimps within ecological carrying capacity and economic feasibility seems to be the goal needed to be achieved in order to bring back Sidoarjo to be one of the biggest districts exporting shrimps. Decision makers, i.e. policy makers and farmers are challenged with the responsibility of planning and conducting aquaculture development in a sustainable way whereby social, ecological and economic goals are simultaneously satisfied. Cobb-Douglas Production Function is one of the methods used to know which input highly affects the shrimp production, continued by Investment Analysis i.e. Discounted Criteria methods that include NPV, Net B/C and IRR to see which system is feasible. As for ecological sustainability, this research uses water quality data translated into Pollution Index as an indicator. And from survey that has been done in Sidoarjo district from May 2013 to October 2013, using Pollution Index analysis show that ponds in Sidoarjo are moderately polluted, the next analysis using regression for Cobb-Douglas Production Function stated that in traditional system production factors that statistically significant arepond area, harvest and pond preparation labour, dissolved oxygen and ammonia. In traditional plus system, pond area, fertilizer, saponin and ammonia seems to be statistically significant. The best shrimp cultivation system would be Traditional Plus Polyculture between shrimp and milkfish that has NPV IDR 6.036.817.617, Net B/C 2,91 and IRR 51% compared to other systems such as Traditional Monoculture, Traditional Plus Monoculture and Traditional Polyculture. Keywords: shrimp farming system, Sidoarjo, pollution index, economic efficiency, business feasibility

Abstract

The objective of the research is to explain about the rules of the traditional social institution, especially characteristic and typology of property rights on artisanal fishery management system at Abang island. Traditional institution pattern commonly has function for keeping continuity of coastal resources, so management that did by local fisherman society in coastal villages feel to keep well fishery resources and ecosystem, not disturbed by capture activity for example intake of rock, bombardment of fish and usage of potassium. Study case method that using is rural rapid appraisal (RRA) for coastal community. This research was done in Abang island village Galang subdistrict Batam city, try to identify and documentating several characteristic and typology of property rights on artisanal fishery at Abang island village. Based on result of research there are 8 fishing gears that dominant used by local fisherman, and other 2 modern fishing gears. Operation of trawl that has been prohibited based on Keppres No. 39/1980, still found in territorial water of Abang island. Eight of fishing gears that operated by fisherman, had fishing ground in around of territorial coastal water, farthermost catch fish by distance 3 or 4 miles from coast line. Generally fisherman here included small scale and traditional fisherman category, meant they become fisherman hereditarily, heritage of their parents, by using simply fishing gears, but they orientated to market, most of catch fish and prawn sold to merchant and tauke, called artisanal fisherman. For appliance catch selected like line, fisherman of Abang island catch fish collectively by using fish aggregating device cooperation result among fisherman. Most of fishing gears used by fisherman in this area are trap, line, longline, setnet, gillnet, fish cage, seine and fish-net. From a number of fishing gears divided again become some types, like net consist of beach seine, apollo net (trammelnet), trawl kara ( Lobster), stromateus net, gillnet and crab net.
