Abstract

Rawapening is a distric of lake equatorial which has many potential benefit such as fishery, recreation facilities, Eceng gondok plant, etc. The water quality there is damagedend disturbed by fishery increacing and Eceng gondok growth. The changeness of equatorial quality can be identifies by richness of fitoplankton’s compotition. That is because fitoplankton makes an important contribution in equatorial ecosistem as primer produsen in food equilibrium and that can respons the environment’s change. The sampling’s dot is chosen by sampling random methode in five different sampling dot including the area of Kali galeh, Bukit cinta, Asinan, Seraten, and Tuntang. The primer parameter in this research is the community structure of fitoplankton and the secondary parameter is physic and chemis factor in equatorial ecosistem like pH, turbidity, temperature, brightness, speed of waves and oxygen demand. The result of this observatory found 16 genus of fitoplankton that consist of 4 division : 5 genus of Chrysophyta, 6 genus of Chlorophyta, 3 genus of Cyanophyta and 2 genus of Dynophyta. Most of fitoplankton population is dominated by spesies of Melosira. The saprobik index shows value 1,63 that indicated the water of equatorial ecosistem is poluted low in Oligo fase / β- mesosaprobik.

Abstract

This research was conducted  to study the plankton community at high tide and low tide of Demaan estuary, Jepara regency and to know the dynamics of abundance. The time of the research was done from April-June 2011. Sampling sites was determined by dividing the 3 stations in the estuary with Stratified Sampling Method, and two stations located on the river (station 4) and sea (station 5). The data determined are abundance index (N), diversity index (H '), evenness index (e), dominance index (C) and similarity index (IS). Physico-chemical factors were measured included water temperature, pH, salinity, DO, depth, turbidity, light penetration, and flow velocity. The plankton was found at high tide and low tide in April was Coelastrum sp. (Chlorophyta). Chaetoceros sp. (Chrysophyta) was found at high tide in May, whereas at low tide was Chlorella sp. (Chlorophyta). In June at high tide, there were found Chaetoceros sp. (Chrysophyta) and Arcella sp. (Protozoa), whereas at low tide were Bacteriastrum sp. (Chrysophyta), and Arcella sp. (Protozoa). The number of species at high tide was higher than at low tide, and the highest number of species present in June. Abundance index of  plankton in the estuary at high tide ranged from 6300-18572 ind/L, whereas at low tide ranged from 3807-17848 ind/L. Diversity index (H ') at high tide ranged from 1,74 to 2,83, whereas at low tide ranged from 1,39 to 3,16. Evenness index (e) at high tide ranged from 0,6 to 0,85, whereas at low tide ranged from 0,63 to 0,86. Dominance index (C) at high tide ranged from 0,08 to 0,33, whereas at low tide ranged from 0,06 to 0,34. Similarity index at station of estuary average are not similar, except at station 1 at high tide and station 2 at low tide in June.Keyword : estuary, high tide and low tide, plankton

Abstract

This research was conducted to determine the influence of combined environmental factors on theoptimum number of spores released from Gelidium sp. The research was done at the laboratory ofMarine Science Development in Jepara.The design of the experiment used was split plot design basedon Completely Randomized Design with three factors : light intensity, photoperiod and salinity. Eachtreatment has three replications. As main plot was combination between light intensity and photoperiodwith three levels respectively           ( 100 lux ; 500 lux ; 1000 lux ) and photoperiod 14 hours light 10 hoursdark ( 14 : 10 hours ; 16 : 8 hours ; 18 : 6 hours ) sub plot was salinity ( 25 %o ; 30 %o ; 35 %o ). Thecollected data were statistically analyzed with ANOVA, followed by DMRT.The result revealed thatthe treatment gave the significant effect on the spores released. The optimum average number of sporereleased of Gelidium sp. Were the combination of light intensity 500 lux, photoperiod 16 : 8 hours andsalinity 30 %o. There was a positive interaction between these three factors in affecting the sporereleased.

Abstract

Diatom is a widespread and cosmopolite micro alga, some can used as bio-indicator of the past environmental change because of its sensivity to its habitat condition and because it is wellfossilized. This study has been done on the estuary of Banjir Kanal Timur Semarang which has ecosystem mangrove; this region is often affected by coast abrasion, flooded by spring-tideinundation water, rain, and freshwater inflow of the river. The study was aimed to examine relative abundance difference, diversity, and vertically variety level of diatom per 2 cm per sediment layer. Sampling method used in the research was “Judgemental Random Sampling”. The result shows that diatom in the mangrove ecosystem of Banjir Kanal Timur Estuary is stable in the upper layer sediment and midle from lower layer and the mangrove ecosystem of Banjir Kanal Timur Estuary is affected by freshwater estuary, based on the domination of the existence of freshwater diatoms (Navicula radiosa, Synedra ulna, Meridion circulare, Sellaphora bacillum, and Eunotia lunula) onthe 8-20 layer.
