ABSTRACT This research was conducted in April-May 2019 in the waters of Poncan Island, North Sumatra Province, which aims to determine the large nutrient content of substrate (nitrate and phosphate), the level of seagrass density Enhalus acoroides, and to determine the effect of nutrient content of the substrate on the density of seagrass Enhalus acoroides. Determination of the research station by purposive sampling and research sampling using the transect line method. The results showed that the highest nutrient content of substrate (nitrate and phosphate) was found at Station II which has a type of muddy sand substrate and the area is influenced by tourist activity.Nitrate concentration values were 0,074 mg / l and 0,122 mg / l for phosphate concentration values.The highest seagrass density was in Station II with a value of 74,22 stands / m2which had the highest nitrate and phosphate content, and the lowest seagrass density was in Station III which had the lowest nitrate and phosphate concentrations.Simple linear regression test results of the influence of nutrient substrate on the density of seagrass with a value of R2(coefficient of determination) = 0,27 (nitrate), 0,40 (phosphate) indicates there was effect of nitrate and phosphate on the density of seagrass Enhalus acoroides.

One of appropriate tourism management models to be implemented while maintaining the sustainability and the beauty of the nature is sustainable tourism activities that have low impact on the environment, otherwise known as ecotourism. With the concept of ecotourism, which combines tourism with nature conservation, is believed to develop the rest of the environmental potential. Developing the natural ecotourism with alignments principles on nature and will be very beneficial to humans. Its usefulness is not only availability of a healthy environment and climate, maintaining flora and fauna that increasingly rare, but also can be a direct lecturing media, both formal and informal levels. Availability of valuable educational ecotourism area has to be monitored seriously so that the chain of intergenerational education of nature is not interrupted. Through ecotourism promoting the values of education, future generations will be more familiar with nature as an integral part of life.Â Keywords: Ecotourism, educational media, environmentCopyright Â© 2015 by Al-Talim All right reserved

AbstractLittorina melanostoma andNerita lineata is a type of snail that use mangrove ecosystems as one of the habitats. Dumai is one of the industrial cities in the province of Riau, where various kinds of human activity can disrupt the ecosystem of mangroves and its associated biota.This research was conducted in January 2018 in mangrove ecosystem of Basilam Baru Dumai City aiming to find out the lenght weight relationship, snail densities, types of mangroves and between mangroverelationship with snails density. That sampling was done by using the transek method on two stations.The results showed the length weight relationship is a negative allometric with the higher density at station I. Six (6) species were found in the mangrove.Relationship between mangrove density with density ofL. melanostomawas found to be weak while the relationship of the density of mangrove with density N. lineata wasstrong relationship.Keywords: Littorina melanostoma,Nerita lineata, Length Weight Relationship, Mangrove

Sponges are the most primitive multicellular animals that live in various types of waters from freshwater, brackish and sea. Sponges live in bottom waters that typically stick themselves on hard substrate such as rock or coral and compete with other tacks organism to obtain a food hall. The research was conducted in Kasiak Island Pariaman regency West Sumatera in February-March 2019, aims to find outthe type, density, frequency of occurrence, diversity index, dominance index, the distribution pattern of sponge, To support the research data is also observed the characteristics of the environment such as water quality. The method used is survey method, where sampling using belt transect method performed on three stations. The research found 14 genus / species of sponge consisting of 11 families in island waters Kasiak with sponge density values obtained in each research station ranges from 1458-4208 ind / ha. The highest frequency of occurrence of the type Jaspis sp. with the frequency of occurrence of 100%. Diversity index values ranged from 1.8921 to 1.9488, dominance index value obtained was from 0.3163 to 0.3396, and the value of the distribution pattern of the sponge ranges from 0.2941 to 0.3015.
