 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.

In 1997, the worst forest fire in Indonesia occurred and hit mangrove forest areas including in Sembilang National Park Banyuasin Regency, South Sumatra. Therefore, the Indonesian government keeps in trying to rehabilitate the mangrove forest in Sembilang National Park. This study aimed to identify the mangrove forest changing and to predict on the future year. The situations before and after forest fire were analyzed. This study applied an integrated Markov Chain and Cellular Automata model to identify mangrove forest change in the interval years of 1989–2015 and predict it in 2028. Remote sensing technology is used based on Landsat satellite imagery (1989, 1998, 2002, and 2015). The results showed mangrove forest has decreased around 9.6% from 1989 to 1998 due to forest fire, and has increased by 8.4% between 1998 and 2002, and 2.3% in 2002–2015. Other results show that mangroves area has continued to increase from 2015 to 2028 by 27.4% to 31% (7974.8 ha). It shows that the mangrove ecosystem is periodically changing due to good management by the Indonesian government.

Terletak di sekitar Selat Madura, Kabupaten dan Kota Probolinggo merupakan habitat dari vegetasi mangrove, tetapi keberadaan hutan mangrove di lokasi ini sebagian besar telah dikonversi menjadi areal pertambakan. Vegetasi mangrove yang tersisa tumbuh hanya di pematang tambak dan di sekitar bagian pantai. Potamididae merupakan satu-satunya famili dari gastropoda dimana semua anggotanya hanya dapat ditemukan berasosiasi dengan vegetasi mangrove. Tujuan dari penelitian ini adalah untuk mengetahui komposisi spesies keong Potamididae di areal pertambakan Probolinggo. Penelitian dilakukan pada bulan Februari dan April 2013 menggunakan metode Purposive Random Sampling di tujuh stasiun penelitian. Identifikasi spesies keong Potamididae dilakukan terutama berdasarkan karakter morfologi cangkang. Hasil penelitian menunjukkan bahwa delapan spesies keong Famili Potamididae ditemukan pada lokasi ini. Keberadaan vegetasi mangrove, jarak terdekat dengan garis pantai, suhu, salinitas dan pola arus serta pasang surut air laut dicatat sebagai faktor pendukung pertumbuhan dan perkembangan keong di lokasi penelitian. Hasil dari penelitian ini diharapkan dapat membuka peluang penelitian selanjutnya untuk mengetahui peran dan pengaruh keong Potamididae bagi kesehatan ekosistem habitat mangrove di area pertambakan.COMPOSITION OF POTAMIDID SNAILS IN THE MANGROVE ECOSYSTEM OF PROBOLINGGO POND AREA, EAST JAVA. Located around Madura Strait, Probolinggo City and Regency is a home for mangrove vegetation, but the mangrove forest in this are mostly has been converted into aquaculture ponds. The mangrove relic grows in the pond embankment and the narrow strip along the seaside. Potamididae is the only family of gastropods in which all members can only found associated with mangrove vegetation. The aim of this research was to determine species composition of potamidid snails in the pond environment of Probolinggo. The research was conducted in February and April 2013 using Purposive Random Sampling method in seven sampling stations. The species identification of the snails was based primarily on morphological shell characters. The results showed that eight species of Family Potamididae were found at the sites. The presence of mangrove trees, the distance to nearest coastline, temperature, salinity, and the pattern of ocean current and tide seemed to support the snails to grow and thrive in the study sites. The results of this study are expected to open up opportunities for further research to determine the role and influence of potamidid snails on the ecosystem health of mangrove habitat in the pond environment.
