Abstract

Selama ini pengelolaan sumberdaya alam hanya didasarkan pada pemenuhan aspek ekonomi serta hubungan yang bersifat fisik (physical interrelationship). Hal ini dapat diperhatikan adanya kecenderungan pengelolaan sumberdaya alam sebatas program konservasi lingkungan fisik seperti hutan, tanah, air dan bukan pengelolaan sumberdaya alam yang bertujuan untuk keberlanjutan sumberdaya alam (natural resources sustainability). Dengan demikian maka dapat dipastikan lambat laun atau cepat akan terjadi degradasi atau penurunan kualitas lingkungan yang pada akhirnya dapat menimbulkan bencana ekologis (Hadisusanto et al., 2003).

Abstract

A survey on abundance of Giant Clam in coral reef ecosystem at PariIslandhas not been done long after the first survey on 1984. The survey itself is very important because Indonesian government has been release SK Menteri Kehutanan No. 12/Kpts-II/1987 and PP No. 7. th.1999 that states the giant clam is protected species. Indonesia has seven species of giant clam out of nine species presence in the world, i.e. Tridacna gigas, T.crocea, T. maxima, T. derasa, T. squamosa, Hippopus hippopus, and H. porcellanus (Rohmimohtarto dkk, 1987, Knop, 1996)

Abstract

Primary productivity of Jombor Swamp, Klaten has been assessed in order  to understand its water quality. The method used was using light-dark bottles incubated for 4 hours. Samples were taken between 6-10, 10-14 and 14-18 hour, under the depth  0.2, 1.5, and 3 m. The results showed  that productivity in April – 2.4 to 2.17 ppm, May –0.6 to 2 ppm, and June –2.1 to 3.4 ppm. The regression correlation of the productivity to phytoplankton`s density is y = -0.03 + 0.01 x and r = 0.76, productivity to light intensity is y = -5.04 + 0.01 x and r = 0.63, productivity to water depth is y = 0.56 + 0.12x and r = 0.31,  productivity to turbidity is y = 1,78 + 0.33x and r = 0.35, productivity to water temperature is y = 1.91 – 0.08x and r = 0.32, productivity to pH is y = 1.39 – 0.71x and r = 0.20,  and productivity to CO2 content is y = 1.77 – 0.11 and r = 0.29. Based on the overall findings, the water quality condition was classified as eutrophic.

Abstract

A study on sediment texture to the abundance of Polycentropodidae’s larvae has been done in Sermo Water Reservoir, Kulonprogo, Yogyakarta. Samples have been taken in 3 rivers i.e. Ngrancah, Tegalrejo and Sidowayah. Four different depth were assessed i.e. 0 – 5 m, 5 – 10 m, 10 – 15m, and 15 – 20 m. Result showed that the larvae’s abaundance was hishest in Ngrancah river on depth of 0 – 5 m with 53 ind/m2 and lowest on Tegalrejo river on depth of 15 – 20 m with 3 ind/m2. The larvae’s abundance in every depth was characterized by sand texture and its depth.
