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.

Abstract

Sayung coast is a area with a growing residential, sea ranching, and industrial area. Those aspects produce create waste that could harm the environment, directly or indirectly. Plankton is a biologic component that is used to indicate the changes of water quality in waters that has been polluted. These goals of this research are to know the water quality in Sayung coast area from the abundance of the plankton,  physical-chemical parameter of the water, and also the status of water saprobity. The samples are taken in July 2017 and April 2018, in Sayung coast waters, Demak. Plankton sampling and water from 5 sampling stasions are considered to represent the diversity of the plankton and water stability. Plankton is sampled using plankton net No.25, then preserved using 70% alcohol + 4% formaldehyde. The abiotic data measureted is nitrate content, temperature, pH, salinity, DO, and turbidity. Data analysis are done using Shannon Weiner’s diversity index (H’), diversty index (e), domination index (C), saprobic index. The result shows that there are 49 species of planktons are found, which are 38 fitoplankton, and 11 zooplankton. The highest group is Bacillariophyta which is 14,24%. The diversty index value of H’ 1,58 – 2,45; therefore the Sayung coast waters is catagorized as stable. The index value of e ranges from 0,64 – 1; index C values ranges from 0,08 – 0,22; and the saprobirity index value is in β-Meso/Polisaprobik to α-Mesosaprobik phase with a very light to very high pollution levels. The physical-chemical parameter analysis of Sayung coast waters in overall is still suitable to support plankton’s life.

Abstract

Environmental pollution has become a serious problem in marine environment. Inorganic pollutants was harmful to the environment because difficult to decompose naturally, therefore induce  environmental damage. One anorganic pollutants agent is heavy metal copper (Cu). Algae have a high tolerance to heavy metal copper stress in the environment so it can be used as a bioremediation agent, such as  Chlorella vulgaris Beijerinck. This study aimed to determine the effect of copper to the population growth of Chlorella vulgaris Beijerinck. Research was carried out by inoculated Chlorella vulgaris Beijerinck in seawater culture medium containing copper (Cu) with concentration 0.05 ppm, 0.5 ppm, 5 ppm, and 25 ppm, respectively.  Observation of the growth of Chlorella vulgaris Beijerinck were performed every 24 hours for 14 days by Improved Neubauer Haemocytometer. The results showed that copper with concentration 0.05 ppm and 0.5 ppm increased Chlorella vulgaris Beijerinck  growth populations at day three and  it also inhibit Chlorella growth until day eigth. Chlorella  population then increased sigificantly at day eight until day fourteen of observation.  Copper  with concentration  5 ppm and  25 ppm decreased the population of Chlorella vulgaris Beijerinck and then increased its population at day six. Chlorella population then decreased at ten day of observation.   Key words: growth, heavy metals copper (Cu), Chlorella vulgaris Beijerinck, bioremediation

Abstract

Industrial products such as metal and paint had generate hazardous wastes, one of then is a heavy metal Chromium (Cr). Industrial wastes containing Cr may cause many negative effects when directly discharged to environment without any prior processing. Therefore, recovery actions (remediation) is one of many ways to solve the problem. Phycoremediation is one of remediation that is simple, efficient and safe in process by using the microalgae to remediate the environment, and one of the microalgae is Spirulina platensis (Gomont) Geitler. This study was conducted to determine the effect and the removal efficiency of heavy metals Cr on Spirulina platensis culture media. The results showed there was significant influence between the administration of heavy metal Cr 1 mg/l, 3 mg/l and 5 mg/l Cr on the population growth of S. platensis. Heavy metal Cr concentration of 1 mg/l increased the growth of S. platensis, while the opposite happened when administrated with 3 mg/l and 5 mg/l. Higher concentration of heavy metal Cr on culture media decreased population of S. platensis. The culture added with heavy metal Cr concentration of 1 mg/l, 3 mg/l and 5 mg/l on the 7 days treatment were able to decrease heavy metal Cr level respectively 35%, 14% and 8%. Thus, the longer treatment days the bigger decrease percentage concentration of heavy metal Cr. Keywords: Cr, phycoremediation, microlagae, Spirulina platensis

Abstract

Polychaeta is a biota that became one component of the food chain in the ocean. Having different tolerances, so it is often used as an indicator of changes in water quality. This study examines the composition of polychaeta which includes abundance, dominance, diversity, evennes, and its distribution patterns at two different locations, ie mangrove vegetation and fish farming areas. Location was chosen by looking the land use’s differences in the coastal area of Mangkang Kulon Tugu Subistrict Semarang. Sampling was conducted in July and August 2012. Analysis of physico-chemical parameters to the water samples and the substrate did directly in the field and laboratory. Samples of polychaeta were obtained by a 1 mm benthic sieve. Identifications are made to genus level. Then, calculating the number of genus, abundance, dominance, evennes, diversity and distribution patterns in each station. Overall, there are 15 genus come from polychaeta, they are Capitellidea, Nereididae,  Spionidae, Dorvillidae, Lumbrineridae, Cirratulidae, Oenoidae and Sabellidae. The average of polychaeta abundance index is in the above of 500 ind/m2. Diversity index (H') is relatively sufficient (1,332-2,073). Evennes index value (E) is high (>0,6) and there is no dominat genus with dominant index (D) low (<0.5). The distribution pattern is the same (Id: <1). The Differences sampling location affect on the composition and distribution patterns of the Polychaeta and physico-chemical factors. While sampling time does not affect the composition and distribution patterns of polychaeta and physico-chemical factors waters. Capitellidae is an opportunistic polychaeta that is more common in fish farming areas (70-81%) than in the mangorove vegetation areas (59 -72%). Keywords: Polychaeta, Mangkang Kulon, mangrove, fish farming, composition, distribution pattern,
