The diversity of mangrove vegetation is a community that has different characteristics from other communities. Diversity is an important component in mangrove management, but so far the availability of data related to mangroves is still very minimal, including those related to the species diversity of mangrove forest vegetation in the region. This study aims to obtain data on species diversity of vegetation found in the mangrove forest area of Dusun Besar Village, Pulau Maya District, Kayong Utara Regency. Method used was a combination of path and plot method, and the determination of the location and research path location were carried out using purposive sampling. The results of observation and data analysis showed that the dominant vegetation species with the highest importance value index (INP) for seedlings, saplings and trees was the Avicennia marina, namely the INP value of seedlings 37.04%, the INP values of sapling 65.24%, and the value of INP a tree rate of 65. Based on the results of the most dominant analysis found the species of  Avicennia marina with a value of C = 0.03430 for seedling, C = 0.04729 for sapling, and C = 0.04736 for tree level. The diversity of mangrove forest vegetation species in Dusun Besar Village for seedlings, saplings and trees is low because it has an H 'value <1, and the abundance of mangrove vegetation species was not evenly distributed in each forest area because it only has an e value <1.Keywords: Dusun Besar Village, Mangrove Forest, Species Diversity

 Substrat mangrove terdiri atas fraksi pasir (sand), lumpur (silt), dan liat (clay). Gastropoda adalah kelompok hewan dari filum moluska yang hidup di jenis substrat dari kasar ke halus. Kelimpahan gastropoda dipengaruhi oleh substrat dasar yang merupakan habitat dari gastropoda, serta kandungan nutrien yang berbeda pada tiap fraksi akan mempengaruhi kelimpahan Gastropoda yang berada di dalamnya. Oleh karena itu, perlu dilakukan penelitian mengenai hubungan substrat dengan kelimpahan Gastropoda, karena Gastropoda salah satu faktor penting untuk menjaga keseimbangan ekologi pesisir khususnya ekositem mangrove. Penelitian  dilakukan di Hutan Mangrove Kulonprogo Yogyakarta bertujuan untuk mengetahui tipe substrat, kelimpahan Gastropoda dan hubungan kedua variabel tersebut. Penelitian  dilakukan pada bulan April sampai dengan  Mei 2017. Metode yang digunakan adalah metode deskriptif yaitu metode penelitian yang memberikan gambaran secara sistematis, faktual, akurat mengenai faktor-faktor dan sifat-sifat dari suatu daerah atau populasi. Metode pengambilan sampel substrat dan Gastropoda menggunakan metode Purposive Sampling Method pada 3 stasiun berbeda yaitu stasiun I pada bagian dekat pemukiman penduduk, stasiun II pada bagian dekat tambak, dan stasiun III pada bagian muara sungai. Hasil penelitian menunjukkan jenis substrat pada tiap stasiun adalah lempung dan lempung berdebu yang didominasi oleh fraksi lumpur (silt) dan pasir (sand). Jenis Gastropoda yang didapatkan berasal dari genus Littoraria, Natica, Faunus, Cerithium, Neritina, Polinices, Conus, Telescopium, dan Nerita. Meningkatnya prosentase fraksi pasir (sand) dan liat (clay) akan diikuti oleh meningkatnya kelimpahan Gastropoda, sedangkan untuk fraksi lumpur (silt) akan sebaliknya yaitu meningkatnya fraksi lumpur akan diikuti oleh menurunnya kelimpahan Gastropoda. Kata kunci: Tipe Substrat, Gastropoda, Mangrove, Kulonprogo  Mangrove substrates formed by sands, silts, and clays. Gastropods is a group of animals of the phylum of mollusks lives on the type of substrate from rough to smooth. Gastropod abundance is affected by substrate which habitat of gastropods and nutrients influencing the distribution of gastropods. Therefore, it needs a deeper research about the correlation of substrate and the amount of gastropods , because gastropods are the importants factor of mangrove ecosystem. The research helds in Kulonprogo Mangrove Forest, Yogyakarta, and the goals are to know the type of substrate, the amount of gastropods, and the correlation among them. This research held on April – Mei 2017. This research use descriptivemethod wich research method that provide a systematic, factual, accurate description of the factors and quality an area or population. The method on sampling sediments and gastropods is purposive sampling in 3 station. Station 1 near the settlement, station 2 near ponds, station 3 on the estuary. The results of this research shows that the sediments on every station are clay and dusty clay, which is dominated by silt,and sand fraction. The gastropods that obtained are Littoraria, Natica, Faunus, Cerithium, Neritina, Polinices, Conus, Telescopium, and Nerita. The percentage increasing on sands and clays fraction would be more gastropods. Otherwise on silts fraction.

Abstract. Isroni W, Islamy RA, Musa M, Wijanarko P. 2019. Short Communication: Species composition and density of mangrove forest in Kedawang Village, Pasuruan, East Java. Biodiversitas 20: 1688-1692. Mangrove is one of ecosystems located in estuary and shallow coastal waters and its existence has a significant role for life. The aim of this study was to identify species composition and density of mangrove forest in Kedawang village, Nguling Sub-district, Pasuruan District, East Java, Indonesia. Survey method using belt transects was carried at three sampling points. Results of this study showed that mangrove vegetation in Kedawang includes five species from three families, namely Avicenniaceae (Avicennia alba and Avicennia marina), Rhizophoraceae (Rhizophora apiculata and Rhizophora mucronata), and Sonneratiace (Sonneratia alba). At sampling point 1, A. alba dominated with a density of 37 individuals/ha at tree level, 380 individuals/ha at pole level and 3100 individuals/ha at stake level. At sampling point 2, the tree level was dominated by A. alba with 142 individuals/ha, while R. mucronata dominated the pole and stake level with 1300 and 1467individuals/ha, respectively. At sampling point 3, the pole and stake level was dominated by A. alba with 167 and 933 individuals/ha respectively, while A. marina dominated the sapling level with 800 individuals/ha. At all stations, the density at stake level is greater than that tree level. Therefore, it is necessary to carry out conservation efforts in the form of protection combined with restoration by enrichment planting at all study locations to increase the diversity and density of mangrove vegetation.
