 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.

The mangrove ecosystem is one of the ecosystems in the estuary area that is unique and very sensitive to environmental changes. The large number of aquaculture businesses around Cemare Hamlet, West Lombok Regency have resulted in many mangrove areas being converted into pond cultivation locations. This will have an impact on the life of mangrove ecosystems such as plankton. This study aims to determine the abundance of plankton species around the mangrove area of ??Dusun Cemare, Sheet Selatan Village, West Lombok Regency. The research was conducted in May-October 2019 using a purposive sampling method by determining 7 stations to represent water conditions. Plankton analysis using the Lackey drop microtranscting method. The results showed that the mangrove ecosystem in Dusun Cemare was composed of 4 types, namely: Rhizophora sp., Avicenia sp., Bruguiera sp., And Soneratia sp. The plankton community in mangrove waters is composed of 13 types, while the abundance of plankton species (periphyton) attached to the mangrove roots consists of 6 types. The composition of plankton species which tends to be high indicates that the mangrove waters of Dusun Cemare are still feasible to sustain the survival of the associated biota in it.
