Abstract

Ekosistem mangrove terdapat di seluruh pantai maupun pulau-pulau kecil Indonesia yang terpengaruh oleh pasang surut. Kajian pola sebaran, indikator kualitas lingkungan dan ekologi komunitas mangrove Pulau Tunda dilakukan pada bulan Januari 2014 dengan tujuan untuk mengetahui pola sebaran, indikator kualitas lingkungan dan ekologi komunitas mangrovenya. Sampel mangrove diambil menggunakan transek garis dan plot yang ditarik dari titik acuan (tegakan mangrove terluar) serta tegak lurus garis pantai sampai ke daratan. Kemudian transek garis tersebut dibuat petak-petak contoh (plot) yang berukuran 10 x 10 m2 untuk kategori pohon dan di dalam ukuran 10 x 10 m2 dibuat plot berukuran 1 x 1 m2 untuk kategori semai. Pola penyebaran mangrove Pulau Tunda dianalisis berdasarkan indeks Morisita. Sementara kualitas lingkungan hutan mangrove dianalisis menggunakan tutupan pohon, tutupan semai dan jumlah jenis semai yang ditemukan. Kemudian ekologi komunitas mangrove Pulau Tunda dianalisis berdasarkan indeks keanekaragaman, dominansi dan keseragaman. Hasil penelitian menunjukan bahwa pola penyebaran mangrove Pulau Tunda tergolong beraturan (regular), dimana terjadi interaksi negatif antar individu dalam memperebutkan ruang, unsur hara maupun cahaya matahari. Selain itu, kondisi hutan mangrove Pulau Tunda masih tergolong baik dengan tingkat kualitas lingkungan vegetasi mangrove 73.74%, keanekaragaman dan dominansi mangrovenya tergolong rendah (1.20 dan 0.52) dan keseragamannya tergolong labil (0.60). Mangrove ecosystems are found throughout the coast and small islands of Indonesia which are affected by tides. Distribution pattern studies, environmental quality indicators and the ecological mangrove community of Tunda Island were carried out in January 2014 with the aim to determine distribution patterns, indicators of environmental quality and ecology of the mangroves community. Mangrove samples were taken using line transects and plots drawn from reference points (outer mangrove stands) and perpendicular to the coastline to the mainland. The line transect is made of plots of sample size 10 x 10 m2 for the category of trees and in a size of 10 x 10 m2 a plot of 1 x 1 m2 is made in the seedling category. The pattern of distribution of mangroves of Tunda Island was analyzed based on the Morisita index. While the environmental quality of mangrove forests was analyzed using tree cover, seedling cover and number of seedlings found. The ecology of the Tunda Island mangrove forest community was analyzed based on the diversity index, dominance and uniformity. The results showed that the pattern of mangrove distribution of Tunda Island was regular, where there was a negative interaction between individuals in fighting over space, nutrients and sunlight. In addition, the condition of the Tunda Island mangrove forest is still relatively good with the level of environmental quality of mangrove vegetation 73.74%, the diversity and dominance of mangroves are relatively low (1.20 and 0.52) and uniformity is classified as unstable (0.60).

Abstract

Ekosistem mangrove adalah ekosistem yang unik, sangat rentan, tetapi paling produktif diantara ekosistem lainnya. Salah satu manfaat hutan mangrove adalah sebagai tempat hidup berbagai biota pesisir dan laut. Penelitian tentang inventarisasi jenis mangrove dan biota asosiasi gastropoda serta distribusi dan konektivitasnya telah dilakukan di Pulau Tunda Serang Banten pada bulan Januari 2014 yang bertujuan untuk mendata keanekaragaman hayati di Indonesia. Stasiun 1 berada di bagian Timur pulau, sedangkan Stasiun 2 berada di bagian Selatan pulau. Data kondisi vegetasi mangrovenya dikumpulkan dengan cara membuat transek garis dan plot berukuran 10 x 10 m2, 5 x 5 m2 dan 1 x 1 m2 yang ditarik dari titik acuan (tegakan mangrove terluar) dan tegak lurus garis pantai sampai ke daratan, sedangkan data kondisi biota asosiasi gastropodanya dikumpulkan dalam plot berukuran 1 x 1 m2 yang dipasang dalam plot transek vegetasi mangrove berukuran 10 x 10 m2. Kemudian distribusi mangrove, biota asosiasi gastropoda dan konektivitasnya dianalisis menggunakan Analisis Faktorial Koresponden (AFK). Hasil penelitian menunjukan bahwa terdapat 5 jenis mangrove dan 20 jenis biota asosiasi gastropoda. Kerapatan mangrove untuk kedua stasiunnya bervariasi, dimana untuk kategori pohon dan semai kerapatan tertingginya pada bagian Selatan, sedangkan kerapatan anakan pada bagian Timur. Sementara untuk biota asosiasi (gastropoda), kepadatan tertinggi untuk kedua stasiunnya adalah L. scabra (6,31 dan 2,24 ind/m2). Distribusi jenis mangrove berdasarkan AFK dikelompokan menjadi dua kelompok, sedangkan distribusi gastropodanya menjadi 3 kelompok. Selanjutnya spesies mangrove R. apiculata memiliki hubungan yang kuat terhadap spesies gastropoda L. scabra, kemudian B. gymnorrhiza dan R. stylosa berkaitan erat dengan C. cingulata maupun T. sulcata, sedangkan R. mucronata, L. racemosa maupun S. caseolaris berkaitan erat dengan gastropoda T. palustris, N. planospira dan M. puella.Mangrove is an unique and susceptible ecosystem, but the most productive than others ecosystem. One of the mangove forest function is as a living place for many coastal and sea biota such as sea gastropods. The research is included some activity to inventory the mangrove and sea gastropod as association biota with it’s spacial distribution and connectivity. It was conducted in Tunda Island Serang Banten on January, 2014 with the aim to collect biodiversity data in Indonesia. Station one (1) is on the East part of the island, while station two (2) on the South part. The mangrove vegetations condition data were collected by line transect and plot (10 x 10 m2, 5 x 5 m2 and 1 x 1 m2) method. It is pulled from the point reference direction (the outer mangrove stand) perpendicular to the shoreline from the main land and divided into 2 (two) research station located on east and south part of the island. While, the associations biota (sea gastropod) condition data were collected by plot size method (1 x 1 m2) located on mangrove vegetation transect plot (10 x 10 m2). Mangrove and gastropods spacial distribution and it connectivity were analyzed by Correspondent Analysis Factorial (CAF) function in SPSS (Statistical Package for Social Science) software. The spacial distribution results shown there were 5 (five) mangrove species and 20 (twenty) sea gastropods. Mangrove density for both station is variated, which for the highest tree and seedling density category stranded on the South part of the island, while for sapling on the East part. While, the highest densities of L. scabra (sea gastropod) as mangrove asscociation biota are located in both station (6.31 and 2.24 ind/m2). According to CAF analysis, the mangrove species are distributed into 2 (two) groups, while, gastropods are distributed into 3 (three) groups for its connectivity measurement. The results showns that mangrove species of R. apiculata has strength relation with gastropods species as gastropoda L. scabra. Therefore, B. gymnorrhiza and R. stylosa has strength relation with C. cingulata and T. sulcata, whereas, R. mucronata, L. racemosa and S. caseolaris has strength relation with gastropoda T. palustris, N. planospira and M. puella.

Abstract

Hutan mangrove memiliki lingkungan yang sangat kompleks, dimana di dalam dan antar lokasi habitat mangrove saling berbeda. Kajian karakteristik lingkungan penentu distribusi dan kepadatan fauna makro bentik serta hubungannya (studi kasus gastropoda dan kepiting brachyura di kawasan reboisasi mangrove Kepulauan Seribu) telah dilakukan pada bulan Maret 2014. Hal ini bertujuan untuk mengetahui faktor-faktor lingkungan yang berperan terhadap distribusi dan kepadatan gastropoda maupun kepiting brachyura serta untuk mengetahui hubungan antara karakteristik lingkungan dengan distribusi dan kepadatan gastropoda maupun kepiting brachyura di kawasan reboisasi mangrove Kepulauan Seribu. Pengukuran karakteristik lingkungan dilakukan dengan cara insitu, sedangkan data gastropoda dan kepiting brachyura dikumpulkan dengan membuat transek garis dan plot yang ditarik dari titik acuan (tegakan mangrove terluar) dan tegak lurus garis pantai sampai ke daratan. Faktor-faktor lingkungan yang menentukan distribusi dan kepadatan gastropoda maupun kepiting brachyura dianalisis menggunakan Principal Component Analysis (PCA), sedangkan hubungannya digunakan analisis regresi linier sederhana. Hasil kajian memperlihatkan bahwa karakteristik lingkungan yang paling menentukan distribusi dan kepadatan gastropoda maupun kepiting brachyura di kawasan reboisasi mangrove Kepulauan Seribu adalah parameter pH. Hal ini mengindikasikan bahwa semakin tinggi konsentrasi pH perairan, maka kepadatan gastropoda maupun kepiting brachyura juga semakin tinggi. Begitu sebaliknya, semakin rendah konsentrasi pH perairan, maka kepadatan gastropoda dan kepiting brachyura juga semakin menurun.Mangrove forests have a very complex environment, where in and between locations mangrove habitats are different. The study of environmental characteristics determining the distribution and density of benthic macrofauna and their relationship (a case study of gastropods and crab brachyurans in the Seribu Islands mangrove reforestation area) was conducted in March 2014. The research aims to determine environmental factors that contribute to the distribution and density of gastropods and brachyurans crabs and to determine the relationship between environmental characteristics and the distribution and density of gastropods and crab brachyurans in the Seribu Islands mangrove reforestation area. Measurements of environmental characteristics were carried out by insitu method, while data on gastropods and crab brachyurans were collected by making line transects and plots drawn from the reference point (outermost mangrove stands) and perpendicular to the coastline to the mainland. Environmental factors that determine the distribution and density of gastropods and crab brachyurans were analyzed using the Principle Component Analysis (PCA), while the relationship used simple linear regression analysis. The results of the study show that the environmental characteristics that most determine the distribution and density of gastropods and crab brachyurans in the mangrove reforestation area of the Seribu Islands are pH parameters. This indicates that the higher the concentration of water pH, the higher the density of gastropods and crab brachyurans. On the contrary, the lower the concentration of water pH, the density of gastropods and crab brachyurans also decreases.
