Abstract

Mangrove adalah ekosistem yang terletak di sekitar muara dengan karakteristik yang unik. Lokasinya terletak di Pulau Pannikiang Kabupaten Barru (ekosistem alami) dan Desa Tongke-tongke Kabupaten Sinjai (ekosistem hasil rehabilitasi). Ekosistem mangrove baik alami maupun hasil rehabilitasi juga tentunya tidak terlepas dari faktor lingkungan. Faktor lingkungan ini juga akan mempengaruhi biota di dalamnya termasuk Gastropoda dan Bivalvia. Analisis data menggunakan koefisien Jaccard. Tujuan tulisan ini adalah mengetahui kemiripan komunitas Gastropoda dan Bivalvia yang ada di ekosistem mangrove alami dan hasil rehabilitasi. Sampel diambil secara acak. Analisis data menggunakan Jaccard Coefficient. Hasil penelitian menunjukkan kemiripan yang lemah untuk komunitas Gastropoda (56%) dan komunitas Bivalvia (50%).   Kata Kunci : Mangrove, Kemiripan, Gastropoda, Bivalvia, Jaccard

Abstract

Water pollution effect on aquatic organisms and if consumed can affect peoples health. These pollutants can be heavy metals such as Cd, Pb, Cr, Hg, and others. Heavy metals have high levels will cause disorders of the kidneys, brain, severe irritation to the skin, can cause diarrhea and even death. The purpose of this paper is to explain physiological mechanisms that occur in the body of gastropods are linked to pollutants in the water environment. Therefore, monitoring the level of pollution a body of water that is alleged to have suffered contamination is very important. Gastropods are one of the aquatic animals (Class) used as bioindicators and biomonitoring for this group of animals has a high ability to accumulate heavy metals in their bodies compared to other aquatic animals. Gastropods is one bioavailability against metal pollution so that it can be used for environmental monitoring. Littoraria scabra, Nassarius reticulatus, Nerita albicilla, Nucella lapillus, Gibberulus gibbosus, Terebralia palustris, and Telescopium telescopiun always use as biomonitoring metal pollution. The main indicator that can be shown by gastropods is declining abundance and body size. Other indicators are as bioavailability of heavy metals in the soft tissues and shells. The ability of the heavy metal deposits is influenced by environmental factors, body size, weight, and gender. Heavy metals can affect hard, thickness, volume, and color of the shell.

Abstract

The mangrove ecosystem has different density levels per location. It can be influenced by environmental factors or because of human assistance. This research was conducted in Tongke-tongke Village, Sinjai Regency and Pannikiang Island, Barru District. Observations were conducted on three groups, namely groups of trees, stakes, and seedlings. Tree group used plot size 10 m x 10 m, stakes group used plot size 5m x 5m, and the group of seedlings used plot size 1 m x 1m. The result of tree group density will be compared with the standard criteria of mangrove damage of the Minister of Environment to know the criteria and the level of density. The mangrove ecosystem in Tongke-tongke village is overgrown by Rhizophora mucronata and Avicennia sp. and is dominated by R. mucronata with very dense density. In the tree group, R. mucronata has a density of 8020 Ind Ha-1. The mangrove ecosystem in Pannikiang Island is overgrown with Rhizophora apiculata, Rhizophora stylosa, Sonneratia alba, Aegiceras floridum, Ceriops tagal, Avicennia sp., Excoearia agallocha, and Lumnitzera racemosa and has a rare and moderate density. In the tree group, the highest density in C. tagal with a density of 1270 Ind Ha-1 and indicated moderate density. Competition is always there in the ecosystem. The species of this ecosystem is fighting for space and nutrients. Therefore, competition can determine the density of plants in it.

Abstract

Aquaculture is an important sector for Indonesian economic, however, the spreads of diseases during farming remains a problem in developing Indonesian aquaculture. The sponge is known as the source of potential bioactive to combat pathogenic diseases in aquaculture.  However, the intensifying exploitation of wild sponge tends to the depreses population of sponges in nature. This article reviews bioactive originating from sponges and potential methods in developing sponges cultivations under in-situ and ex-situ methodologies.

Abstract

Mangrove merupakan ekosistem yang memiliki beragam manfaat ekologis dan ekonomis. Penelitian ini bertujuan untuk mengetahui pemanfaatan mangrove Rhizophora stylosa di Pulau Bauluang. Data diperoleh melalui observasi lapangan, pemberian kuesioner, dan wawancara terstruktur. Hasil penelitian menunjukkan bahwa masyarakat Pulau Bauluang memanfaatkan mangrove Rhizophora Stylosa untuk berbagai keperluan di antaranya sebagai bahan baku pembuatan arang dan kayu bakar. Mangrove ini juga berperan dalam melindungi pemukiman dari angin laut dan gelombang, serta mempermudah para nelayan dalam menangkap ikan.
