Abstract

Damming river causes fragmentation of the river and changes in hydrologic regime, thus contributing to influence fish. We investigated barb and aimed to examine its reproductive aspects between the zone above and below the Panglima Besar Soedirman Reservoir. Samples were collected from October 2012 to March 2013. Gill nets, cast-net, and electrofishing were used to capture the fish. Samples were analysed to find out the estimate gonad maturity, gonado-somatic index, fecundity, and egg diameter. The first maturity of male gonad size (158 mm in length body) in zone above is smaller than the reservoir (158 mm) and zone below (187 mm). The female has 238 mm of the first maturity of gonad size on the reservoir site, bigger than the zone above (168 mm) and zone below (161 mm). The spawning peak of barb occurs in October based on the gonad maturity stage data and gonado-somatic index. The fecundity of the barb is 2,76025,290 eggs. The fish is total spawner. The reservoir influenced the barb reproduction. AbstrakPembangunan bendungan akan memisahkan sungai dan mengubah rejim hidrologis, yang selanjutnya akan memenga-ruhi kehidupan ikan. Penelitian ini bertujuan mengkaji aspek reproduksi ikan brek pada bagian atas dan bagian bawah Sungai Serayu yang dipisahkan oleh Waduk Panglima Besar Soedirman.

Abstract

Study of The willingness to accept (WTA) is one approach to assess environmental services. The WTA estimates how much people want to be paid to prevent environmental damage (willingness of producers to receive compensation) with the deterioration of environmental quality. Coastal sand mining in Nasai Beach has caused coastal damage, damaged mangrove ecosystems, reduced fisheries production, and caused damage to roads. One effort to overcome this externality through the determination of sand price that internalized the externality cost. The proposed of sand price is IDR 391,924.00 /m3. This study aims (1). Analyzing the willingness to accept ofsand price with internalized the externality cost from consumers of sand, sand agents and sand sellers, (2). Analyzing the level of income and expenditure of the community, (3). Assessing the correlation of WTA values ​​with the level of expenditure and income of respondents. The methodology used mean WTA, Pearson correlation test and cross tabulation. The results showed that 72.3% of respondents were willing to accept the price of sand which internalized the externalities cost. The amount of WTA costs varies between Rp100,000.00 until IDR 1.300.000,00 The Sperman correlation test shows that there is a significant correlation between income and expenditure, between willingness to accept WTA value and WTA value and between expenditure and willingness to accept WTA value. Correlation is low and different directional, except the correlation between income and expenditure is in the same directionKata kunci : Sungai Baturusa, PenambanganTimah, Kualitas Air, IndeksPencemaran.
