Abstract

Diatoms are a micro-alga dominates in the aquatic ecosystem. Their silicious cell wall able to preserve death diatoms in the sediment for long periods of time, therefore, diatoms have an important role in the paleolimnological analysis. Diatoms assemblages in the sediment layer express the water quality whenever the diatom lives. This article provides information how to apply diatom on the paleo-limnological analysis, supporting with the case study in the Lac Saint-Augustine Quebec-City Canada and Rawa Pening Lake Indonesia. Modern diatom and the water quality from spatial and temporal range are used as a calibration set. The diatoms of below layers, then, Weighted Averaging (WA) with the calibration set to reconstruct the water quality in the past. Previously, both in Canada and Indonesia, those lakes were oligotrophic and sharply change into eutrophic condition since a lot of human activities developed around the lakes (anthropogenic factors). Naturally, the maturity of lake can not avoid and the succession had been fast by eutrophication. Paleolimnological approach provides baseline data in the past to develop the appropriate lake management.

Abstract

High sedimentation and the entry of organik and inorganik pollutants, especially P and N, have led to the eutrophication of Rawapening Lake waters. These conditions triggered an uncontrolled booming of water hyacinth aquatic weed (Eichhornia crassipes (Mart.) Solms). The presence of water hyacinth triggers a significant loss of water compared to local weeds through evapotranspiration. The invasion of water hyacinth causes various problems, including depletion of water oxygen content which has an impact on decreasing fish production, damaging natural beauty, and also affecting public health. Many efforts to control water hyacinth in Rawapening Lake have been carried out both physically and by utilizing biological agents. One of the efforts to control the density of water hyacinth in Rawapening Lake is to use it as compost raw material. Water hyacinth contains various elements that are useful for making quality compost, including calcium (Ca), sodium (Na), potassium (K), iron (Fe), copper (Cu), and others. Water hyacinth root contains sulfates and phosphates, the leaves contain carotin and the flowers contain delphinidin-3-diglucosida. The various nutrients contained in water hyacinth make quality compost capable of meeting the nutritional needs of cultivated plants. This article aims to review the use of water hyacinth as a basic material for making compost which is useful for fertilizing agricultural cultivation activities

Abstract

Research on the use of Chorella sp. on reducing of Zn concentrations was conducted in order to know Zn concentration which is maximally absorbed by Chorella sp. In the preliminary experiment, there was the range of Zn concentration that caused the highest population growth of Chorella sp. was 0.1 – 0.4 ppm. In the main experiment, it was divided into five concentrations and one control with three replications. Each of concentrations was treated on Chorella sp. culture with the first Zn concentration (0.0042 ppm) in the medium culture. Those concentrations were 0.05 ppm, 0.15 ppm, 0.35 ppm, 0.45 ppm. All of the concentrations were given on the day of 5. The density of cells which was used for each flask was 100,000 cells/ml. The fertilizers used for each flask were : ZA, Urea, TSP, FeCl3, EDTA. The result showed that there was an interaction between the population growth of Chorella sp. and the reducing of Zn concentration. The highest population growth of Chorella sp. was found in the treatment of 0.15 ppm Zn concentration.

Abstract

Biomonitoring methods for water quality, such as coli form content, diversity and evenness indices of macrobenthic invertebrates and plankton which are recently used, actually have some weaknesses. Escherichia coli only indicated pollution caused by faecal coli; macrobenthic invertebrates have not ability to live in all substratum, whereas the population of phytoplankton are affected by current as they are floating in the surface water. Therefore, the method which are more effective have to be developed. Epipelic diatoms have potential characteristics as bioindicator of water quality because the have ability to accumulate physic-chemical component of aquatic ecosystem and respond it immediately. This research is conducted in order to find out a new alternative of biomonitoring method ( species indices of diatoms ) which are more significant, effective and efficient by determine water quality map absed on diatoms and determines the species which responsible to the grouping. Sediments samples were taken from 7 rivers in the Northern Coast of Central Java (called Pantura): Karanggeneng-Rembang, Juana-Pati, Banjir Kanal Timur-Semarang, Banjir Kanal Barat-Semarang, Banger-Pekalongan, Pekalonghan-Pekalongan, and Gung-Tegal. Temperature, dissolved oxygen, salinity, pH and turbidity were measure in-situ.  Analysis of water and sediment samples include total nitrogen, total phosphorus,silica, heavy metals of Cu, Cr, and Cd. Extraction, preparation and identification of diatoms followed Wetzel & Likens (1991) and Round (1993). The`data were then analysed using Primer package progamme version 4.0 which is produced by Plymouth Marine Laboratory, United Kingdom (Carr, 1997). The Multi Dimentional Scaling (MDS) ordination was done to make grouping and was followed by SIMPER analysis to determine responsible species (Clarke & Warwick, 1994). Based on diatom community, 7 river Pantura could be divided into 3 groups: Group I, consisted of Gung and Pekalongan Rivers, Group II of Banjir Kanal Timur, Barat and Banger Rivers and Group III Karenggeneng and Juana Rivers. Synedra ulna was responsibled for those grouping and are therefore could be promoted as bioindicator of water quality in the Indonesian river. Research still should be developed, especially for diatoms in the bottom layer of sediment samples to reconstruct ecological condition in the past and to predict the condition in the future.

Abstract

The natural mangrove ecosystems along the Northern Coast of Central Java were very limited in extent, even had replanted almost twenty years ago. Naturally, the upper layer of sediment are the latest deposition (superposition). Environmental condition recently are recorded in the top sediment layer, and can be used to reconstruct past condition  (the present is the key to the past). The potential use of diatoms to reconstruct palaeoecology is well established. Diatoms are microscopic algae that form siliceous frustules which make them well preserved in sediment. Diatoms and their assemblages are very useful as integrated indicators of environmental changes because their distribution is closely linked to water quality parameters as well as their affinities to several physical habitats. This research was conducted in order to determine the changes of mangrove ecosystem in the Northern Coast of Central Java based on diatom stratigraphy. Sediment samples from mangrove sites were taken from Pekalongan, Brebes, Semarang, Demak and Rembang. Diatom analysis, consist of digestion, preparation, and identification. The diatom stratigraphy was performed by Software of  C2 1.5.1. Stratigraphycally, the mangrove ecosystems along the Northern Coast of Central Java were previously more influenced by freshwater rather than the marine sources which dominate today.

Abstract

Research on Spirulina sp. has been development since it was found to have a high economic value and as healthful as human traditional food such as the fishes. Therefore, the factors that influence the culturing of this algae should be maintained properly to obtain a high quality of the product. The research was done to determine the interaction of salinity and the dosage of the urea fertilizer on the population growth of Spirulina sp. factorial design with the combination treatment of four salinities (12,5 ppt, 15 ppt, 17,5 ppt, 20 ppt) and three dosage of urea fertilizer (80 ppm, 100 ppm, 120 ppm), are applied with 3 replications. The result indicated that the highest Spirulina sp. population is 321000 unit/ml, wet weight is 3,349 gr/l and dry weight is 1,315 gr/l which was found on the 20 ppt salinity and 120 ppm of urea fertilizer dosage.
