Abstract

Lingula sp. is one of the genera of the Brachiopoda phylum that lives in the intertidal zone or areas that are affected by tides. The purpose of this study was to determine the population structure of Lingula sp. through the approach of population structure, density, distribution patterns, length and weight relationship and with physical and chemical parameters in the waters of Alue Naga, Syiah Kuala District, Banda Aceh City. The method used in this research is a purposive random sampling method. The results show that the growth pattern of Lingula sp. is classified as negative allometric at three research sites in Alue Naga waters, based on the value of b 3. The density of Lingula sp. was the highest at site 1 with a total of 17.7 ind/m2. While the density of Lingula sp. was the lowest at site 3 with a total of 9.7 ind/m2. The distribution of Lingula sp. at the three sites were uniform, with morisita index (Id) values of 0.352, 0.257, and 0.208 for sites 1, 2, and 3 respectively. In addition, the environmental factors of the three research sites in Alue Naga waters are within the normal limits of life for Lingula sp.Keywords: Alue NagaLingula sp. Population structure

Abstract

Coral reef ecosystems have a vital role in waters so that damage to coral reef ecosystems can reduce ecological and socio-economic functions that can impact environmental imbalances, such as reef fish and benthic communities. This study aims to determine the effect of transplant media on the growth rate of the genus Pocillopora coral and see whether it has a significant effect on the rate of coral growth in TWAL Pulau Weh, Aceh Province. The method used is a purposive sampling method in determining stations, analysis using the ImageJ 1.52 application. The results showed that the effect of transplant media on the growth rate of Pocillopora corals were significant differences between structures given an electric current and those not given an electric current with a 95% confidence interval. The average growth value of Pocillopora corals given an electric current is 25.06 mm/month. While the Pocillopora corals that were not given an electric current average growth value was 16.50 mm/month.Keywords:Coral reefCoral transplantElectrical stimulationPocilloporaImagej
