Abstract

The study was intended to observe the vegetation composition and structure of mangrove plants on southern and northern coast of Central Java Province. This research was conducted in July till December 2003, at 20 sites. Laboratory assay was done in Laboratory of Biology Department, Faculty of Mathematics and Natural Sciences, and Central Laboratory of Mathematics and Natural Sciences, Sebelas Maret University (UNS) Surakarta. Data was collected by using belt transect method, from coast line into landward. The result indicated that in common, the trees strata which also have shoots strata and strata of germs (seedlings); and bushes strata which also have strata of germs(seedlings), if they were compared to the same species then their important value tend to be stable. So it was predictable that in the disturbance condition, the preservation of mangrove was guaranteed, as long as there was no great change on a broad scale.© 2005 Jurusan Biologi FMIPA UNS SurakartaKey words: mangrove plants, Central Java Province, composition and vegetation structure

Abstract

The objective sof the research were to study the physical, chemist and biological (plankton) conditions of sewerage disposal from several lndustries In Surakarta, Physical parametert observed were temperature, total soluble solid and the texture of soli sediment, chemistry parameters observed were, includll"l,g,DO, pH and EC, while blotlo parameters observed were density and diversity of plankton, The research was elane, betvleen July and September 2002 at sewerage disposal of ten Industries InS urakarta. Sample collected at 0, 100 16I'1Q 200m irespectlvely from the waste reseuree, Temperature data measured for both water and sediment resulted ,that the average, temper'ature of ten industries was >26°0, with certain Industry clearly dissolved Its high temperatur,e wU,QIi1 its uwer:ag;e., The iSS varies betvleen Industries, depend on the speclfloatlon of the Industry, pH detegteGw,as '1>1, :an;'ct tile 00, data. mee_suredwere relatively high due to aeration process.
