Abstract

ABSTRACT Gastropods and Bivalves are two important classes of molluscs living on the Terkul coastal area. Species of these class are often used by local people for livestock feed, handicraft materials and was consumed. This study aimed to determine the structure of community Gastropods and Bivalves in coastal areas of Terkul Rupat Bengkalis Regency. This research was conducted in February - May 2018. Sample collection of Gastropods and Bivalves taken from on 4 certain stations using quantitative and qualitative methods.From this research were found 17 species, consisting of 13 species of Gastropods and 4 species of Bivalves. The highest density of Gastropods is in Station III of 10.67 ind / m2 with characteristics ie near the Terkul port and mangrove grow rarely. The value of Diversity (H ') is high, ranging from 2.26 to 3.13, the uniformity value (E) is in the range of 0.43 to 0.59, the dominance value (C) ranges from 0.13 to 0.43. The distribution pattern of 12 species is clumped and 1 species is uniform. The highest bivalves density is at station III of 0.56 ind / m2 with characteristics ie near the Terkul port and mangrove grow rarely. The value of diversity (H ') is, ranging from 0 to 1.52, uniformity value (E) is ranging from 0 to 0.75, the dominance value (C) ranges from 0 to 0.37.

Abstract

Abstract N. lineata lives in tropical intertidal areas such as rocky shores, mud and also in mangrove trees while L. melanostoma lives in high ranges of areas in mangrove such as stems and leaves. This research was carried out on May 2018 in Sungai Sembilan District, Dumai City, Riau Province. This study aims to determine the morphometrics of N. lineata and L. melanostoma, the density of mangroves, and the relationships of density of mangroves with N. lineata and L. melanostoma populations in industrial and non-industrial areas. The sampling was done by using line transect method, carried out at 2 stations, station I in the industrial area and station II in the non-industrial area. The results showed that the highest length, width and weight of N. lineata and L. melanostoma were found in non-industrial areas. Simple linear regression analisis between length and wide of N. lineata and L. melanostoma are negative allometrics. The density of mangrove at industrial areas (1255.54 ind/ha) was higher than in non-industrial areas (1033.33 ind/ha). A weak relationship between mangrove density with N. Lineata density in the industrial area was observed (r=0.12), while in the non-industrial area has a moderate relationship (r=0.48). Meanwhile the density of mangroves with L. melanostoma density in industrial areas showed a very weak relationship (r=0.12) and conversely in non-industrial areas showed a strong relationship (r= 0.55).  Keywords: Morphometric, Nerita Lineata, Littoraria melanostoma, Mangrove

Abstract

ABSTRACT Makrozoobenthos is a benthic animal measuring >500µm that lives on the bottom and surface of the water substrate. Makrozoobenthos community structure is influenced by changes in environmental factors. The reseach was conducted in August-November 2018 in the coastal waters of the Karang island of Sosorgadong District, Central Tapanuli Regency, North Sumatera Province.The aims of the research were to determine the structure of the makrozoobenthos community which includes species, abundance, diversity index, uniformity index and dominance index. Sampling used the line transect method at 3 stations. The results of the study found 5class makrozoobenthos consisting of 24 species. The abundance value obtained was in the range of 7-8 ind./m2. Diversity index values ranged from 1.07-1.48, which are classified as moderate, while the uniformity index value ranges from 0.72-0.91 which is balanced. The dominance index value ranged from 0.39-0.59, i.e there are species that dominate.Keywords: Makrozoobenthos, Community Structure, Karang Island

Abstract

ABSTRACT Mangrove ecotourism is an effort to maintain and utilize mangroves. This research was conducted in Sungai Rawa Village, Siak Regency, Riau Province, in September 2019. The objectives of this study were to: 1). Knowing the potential of mangrove ecosystems in Sungai Rawa Village to be developed into a mangrove ecotourism destination, 2). Develop strategies for developing mangrove ecotourism in Sungai Rawa Village. The method used in this study is a survey method. The sampling points and the respondents were determined by the purposive sampling method. The mangrove forest of Sungai Rawa Village has the potential to be developed as a mangrove ecotourism area with good ecological conditions of the mangrove forest, has a high diversity of biota, research and conservation potential as well as a high level of security and hospitality for the community. Community participation in the development of ecotourism in Sungai Rawa Village is classified as low with an IPR value of -0.03 and Mean calculated value of 1.99 while community perceptions about ecotourism development in swamp river villages are high with an IPR value of 2.77 and an average value at 26.65. Based on stakeholder perceptions of the development of Sungai Rawa Village ecotourism is appropriate or feasible to be developed as an ecotourism area. Strategy in developing mangrove ecotourism in Sungai Rawa Village is to implement an aggressive strategy (Growth Oriented Strategy) by prioritizing SO strategies, namely: 1) Establishing mangrove forest areas in Sungai Rawa Village as a conservation area, 2) Increasing access to a wider market, 3) Building collaboration with related agencies and institutions. Keyword: Siak, Ecotourism, Mangrove

Abstract

This research was conducted in January 2019 in the mangrove area of Purnama Village, Dumai City, Riau Province. The purpose of this study was to determine the crab community structure which includes the type, abundance, crab distribution patterns, species diversity (H '), species uniformity (E), and species dominance (C) crabs. The method used in this study is a survey method. There are three observation stations with each of the three transects at each station, on each transect line there is a square plot with a size of 5x5 m2. Crab sampling is done quantitatively and qualitatively. Based on the results of the study it was found that the species of crabs identified at the area of the research were Sesarma reticulatum, S. guttatum, Uca dussumieri, U. rosea, U. vocans, Cardisoma carnifex, and Clistocoeloma merguinse. Furthermore, the abundance of crabs obtained is between 1560-2040 Ind / Ha with cluster distribution patterns. The average value of species diversity (H ') indicates moderate diversity, uniformity (E) indicates high species uniformity, and species dominance value (C) indicates no dominating species.This research was conducted in January 2019 in the mangrove area of Purnama Village, Dumai City, Riau Province.

Abstract

Mangrove forest in Sungai Apit Sub District, Siak District, Riau is one of the mangrove ecosystems in Riau Province which has experienced a reduction in land area and is the widest in Siak Regency. This study aims to determine the perceptions and attitudes of the community in the protection and management of mangroves. The research was conducted in three villages in Sungai Apit Sub District, namely Rawa Mekar Jaya, Sungai Rawa and Mengkapan. Data was collected through observation and interviews with the community using mangroves. The results showed that the perception of the community in Sungai Apit towards the function and management of mangroves is classified as very good, while the attitude of the community towards the protection and management of mangroves is classified as good. The perception and attitude of the people of Rawa Mekar Jaya and Meng Kapan are better than the people of Sungai Rawa. Community involvement in rehabilitation activities is generally only at the time of the project and due to wages. The community has a high awareness of utilizing mangrove resources in a sustainable manner. The community has a high awareness of the protection and management of mangroves, but their involvement in rehabilitation activities requires money to compensate for the time and energy used. Therefore, alternative activities are needed that can increase funding sources and increase funding sources in local institutions related to mangroves.
