Abstract

Macrozoobenthos is a group of organisms that live in or on the surface of bottom sediments and have a length of more than 1 mm. One of the macrozoobenthos habitats is the mangrove ecosystem in the Gosong Telaga Selatan Ecotourism Mangrove, North Singkil District, Aceh Singkil Regency. Knowledge that macrozoobenthos can provide food availability for other organisms and as an indication of the suitability of potential water quality, especially pollution indicators, and plays an important role in the decomposition process of organic material in sediment in the mangrove ecosystem, so that the macrozoobenthos community can be used as an indicator of the balance of the mangrove ecosystem. This research aims to identify the diversity, uniformity, and dominance of Macrozoobenthos in the Gosong Telaga Selatan Mangrove Ecotourism Area, North Singkil District, Aceh Singkil Regency. This research uses a combination of two transect methods, namely line transects and quadratic transects. Determining the research location used the purposive sampling technique. Data analysis uses qualitative and quantitative analysis. The research results show that there are 7 Macrozoobenthos species, consisting of 3 classes, with a total of 182 individuals. Macrozoobenthic diversity in the ecosystem area in the Gosong Telaga Selatan Mangrove Ecotourism, North Singkil District, Aceh Singkil Regency is classified as moderate with a diversity index of Ĥ= 1.35-1.75, the uniformity index is classified as stable, ranging between E= 0.76-0.93, and the dominance index is classified as low.

Abstract

Coastal and marine areas are an integrated ecosystem and are interconnected with each other, so they have a mutual correlation. In a coastal ecosystem, there is an exchange of matter and energy that takes place in the system and with other external system components. Based on the importance of the role of mangrove ecosystems in a body of water and the lack of information about the structure of mangrove communities in Pematang Sei Baru Village, Tanjung Balai District, Asahan Regency, North Sumatra, this research is important to be carried out to determine the condition of mangrove ecosystems and can provide understanding to the community about the importance of ecosystems for coastal areas. The data analysis used in this study is both descriptive and quantitative. The data analysis used includes diversity and uniformity index, dominance, mangrove community structure, and canopy cover. The highest diversity in trees is found at station 3, with a value of 2.20, and the lowest, with a value of 2.12, at station 2. The highest uniformity in trees is found at station 2, with a value of 0.96, and the lowest at station 5, with a value of 0.93. The highest dominance value was in Rhizophora mucronata with a value of 15.75%, Xylocarpus granatum with a value of 11.51%, and Bruguiera cylindrical type with a value of 10.73%. 1 highest INP value is the type of Rhizophora mucronata with a value of 55.79% and canopy cover in the medium category. Based on the results of observations made at the location of this study, there are many remnants of logging carried out by the surrounding community, which, if left unchecked, will lead to reduced land, which will greatly affect the ecosystem in it. Therefore, the role of the government is expected in conducting supervision in this area.

Abstract

Mangroves are a type of vegetation found in tropical coastal areas. In general, mangrove vegetation thrives in sloping coastal areas or near river estuaries and beaches that are protected from waves. The physical function of mangrove forests is to keep the coastline stable, protect the coast from erosion, reduce storms and waves, and catch sediment, while the biological function of mangroves is as a spawning place or residence, shelter for shrimp, crabs, shellfish, and other animals. Research on Mangrove Plant Community Structure in the Kwala Indah Village Area was carried out in August–November 2023 with the aim of determining mangrove types, mangrove diversity and uniformity, dominance, the Important Value Index (INP), and mangrove canopy cover in Singai Apung Village. The method used to observe the community structure of mangrove plants is to use the quadrant transect method by analyzing species density, relative density, species frequency, relative frequency, species dominance, relative dominance, and important value index at the tree level. , saplings and seedlings, as well as canopy cover. Based on the research results, 10 species were found, namely Avicennia alba, Avicennia lanata, Bruguiera cylindrica, Bruguiera sexangula, Excoearia agallocha, Lumnitzera littorea, Rhizophora apiculata, Rhizophora mucronata, Sonneratia alba, and Xylocarpus granatum. Rhizopora mucronata, which has INP, diversity in the medium category, and uniformity in the high category, has the highest dominance in Rhizophora mucronata. Canopy cover is in the dense category.

Abstract

Mangroves are ecosystems in intertidal areas with strong interaction between marine, brackish, river, and terrestrial waters. Mangrove forests are one of the natural resources of coastal areas which have an important role in ecology, economy, and social aspects. The main benefit of mangroves is balancing the ecosystem and providing various life needs for humans and other living creatures. Besides being known to have economic potential as a provider of wood resources, fishing, crabs, and so on, mangrove forest resources also play a role in preventing sea waves and seawater intrusion towards land. The research location is in Mesjid Lama Village, Talawi District, Batu Bara Regency, North Sumatra Province. Mangrove observations used the quadrant transect method, where this research analyzed the types of mangroves, diversity, uniformity of mangroves, dominance, and INP of mangroves, and canopy cover. Three species of mangroves were found in Mesjid Lama Village, Talawi District, Batu Bara Regency, namely Avicenia Officinalis, Bruguiera cylindrica, and Rhizophora apiculata. Keywords: Mangrove Ecosystem, Diversity, Uniformity, Dominance, Importance Value Index, Mangrove Canopy Cover. Abstrak Mangrove merupakan ekosistem yang berada pada wilayah intertidal dimana pada wilayah tersebut terjadi interaksi yang kuat antara perairan laut, payau, sungai dan terestrial. Hutan mangrove merupakan salah satu sumberdaya alam wilayah pesisir yang memiliki peranan penting dari segi ekologi, ekonomi, dan social nya. Manfaat utama mangrove sebagai penyeimbang ekosistem dan penyedia berbagai kebutuhan hidup bagi manusia dan makhluk hidup lainnya. Sumberdaya hutan mangrove, selain dikenal memiliki potensi ekonomi sebagai penyedia sumberdaya kayu, penangkapan ikan, kepiting dan lain - lain, juga berperan untuk menahan gelombang laut dan intrusi air laut ke arah darat. Lokasi penelitian berada di Desa Mesjid Lama Kecamatan Talawi Kabupaten Batu bara Sumatera Utara, Pengamatan mangrove menggunakan metode transek kuadran, dimana penelitian ini menganalisis jenis – jenis mangrove, Keanekaragaman dan keseragaman mangrove, Dominansi dan INP mangrove serta Tutupan kanopi. Jenis mangrove di Desa Mesjid Lama Kecamatan Talawi Kabupaten Batu bara ditemukan 3 spesies yaitu Avicenia oficinalis, Bruguiera cylindrica, dan Rhizophora apiculata. Kata Kunci : Mangrove, Keanekaragaman dan Keseragaman, Dominansi, Indeks Nilai Penting, Tutupan Kanopi.

The purpose of this activity is to provide clean water facilities for local communities to be able to use clean water in their daily activities. The people of Onan Lama Village, Juma Kancil Hamlet really need a real touch to be able to receive direct benefits from the existence of clean water facilities in the location where they live. So far, people have had to walk long distances from the top of the hill to the valley or their neighboring villages which are around 3-3.5 kilometers from their village and have not been touched by the construction of clean water facilities for hundreds of years. So this is very burdensome and not effective and efficient in terms of time, energy and costs. So with this development it is hoped that there will be direct action to the community. So the community really needs the construction of clean water facilities.
