Abstract

Plankton, an aquatic biota, often used as an indicator of water quality. The objectives of the research were to know: (1) diversity of both phyto- and zooplankton at Jabung swamp, East Java; (2) water quality at the swamp, and (3) diversity of fish that act as primary consumer of the plankton. Field sampling procedures were done at the swamp, followed with identification and data analysis at laboratory. Sampling locations were at the inlet, pools in the swamp and at the outlet. Sample were taken triplicate at each location between September and November, 1999 using a plankton net, while fish data were collected by interview and direct observation at the field. Thirty-one species of plankton were found in this research consisting of 17 species of phytoplankton and 14 species of zooplankton. The results of the plankton analysis indicate that Jabung swamp categorizes as moderately polluted at the inlet, polluted free at the pools inside the swamp, and lightly polluted at the outlet. There were 15 fish species found at the swamp both of cultivated and non-cultivated fish.© 2000 Jurusan Biologi FMIPA UNS SurakartaKey words: biodiversity, plankton, Jabung swamp, water pollution

Abstract

Indonesia is an archipelago of 17.508 islands with land width of 1.9 millions km2 and sea of 3.1 millions km2, having many types of habitat and become one of biodiversity center in the world. There are about 28.000 plants species, 350.000 animals species and about 10.000 microbes predicted lived endemically in Indonesia. The country that represents only 1.32% of the world having 10% of total flowering plants, 12% of mammals, 16% reptiles and amphibian, 17% birds, 25% fishes and 15% of insects in the world. Most of the biodiversity were not investigated and utilized yet. The direct use of the biodiversity is not any risk, and in addition, between government, society and industries sometime does not have the same view and attitude. Habitat destruction and over-exploitation have caused Indonesia having long list of endangered species including 126 birds, 63 mammals and 21 reptiles. The extinction of some species occurred just few years ago like trulek jawa (Vanellus macropterus), insectivore bird (Eutrichomyias rowleyi) in North Sulawesi, and tiger sub species (Panthera tigris) in Java and Bali. It seems that now is time for all Indonesians to introspect and look for the way that can be used for preserving biodiversity.© 2001 Jurusan Biologi FMIPA UNS SurakartaKeywords: biodiversity, Indonesia, endangered species
