Abstract

Hutan mangrove merupakan organisme atau tumbuhan yang mampu hidup pada salinitas yang relatif tinggi dan umumnya terdapat di seluruh pantai serta tumbuh berkembang pada daerah yang mempunyai pasang surut air laut. Penelitian bertujuan mengetahui kondisi ekosistem mangrove di Pesisir Selatan Purworejo. Dilaksanakan dari bulan Maret sampai dengan bulan April berlokasi di tiga desa yang berada di Kecamatan Purwodadi, Kabupaten Purworejo, Jawa Tengah. Metode yang digunakan untuk pengambilan data adalah Metode Transek Garis dan Petak Contoh (Transect line plot). Hasil pengamatan ditemukan 3 jenis mangrove, yang ditemukan pada lokasi, yaitu: Rhizophora mucronata, Sonneratia alba dan Avicennia alba, terdapat juga mangrove Acanthus ilicifolius, dan Nhypa fruticans, diketahui juga kerapatan mangrove tertinggi pada stasiun III 9900 Ind/Ha, tutupan jenis Sonneratia alba 50.48, frekuensi tertinggi pada jenis mangrove Sonneratia alba dan Rhizophora mucronata. Indeks nilai penting tingkat pohon, pancang, dan semai yaitu tingkat pohon dari Sonneratia alba sebesar 215, tingkat pancang dari jenis Sonneratia alba sebesar 142, dan semai untuk Rhizophora mucronata dan Sonneratia alba sebesar 100.

Abstract

The aims of this study was to determine the distribution patterns and diversity of seagrass in Pallette and Tangkulara waters. This research was conducted for two months, from August to September 2019. Data collection was carried out at two points with three replications each. Seagrass data retrieval uses the line and quadrant transect method. The results showed that there were 5 species of seagrass found in the Pallette and Tangkulara Waters, namely Enhalus acoroides, Thalassia hemprichii, Halodule uninervis, Cymodocea rotundata, and Halophila sp. The diversity of seagrass species in the Pallette and Tangkulara Waters was in the low category. Distribution patterns of all species of seagrass Thalassia hemprichii Halodule uninervis, Cymodocea rotundata, Halophila sp. has a grouped distribution pattern value while for Enhalus acoroides the distribution pattern is equal.

Abstract

ABSTRACTSeagrass beds have an important role as the main source of primary productivity or organic matter producers, habitat for various biota, nursery grounds, spawning grounds, food sources for rare biota, and support for the diversity of marine biota species, as well as the economic value of seagrass ecosystem services. This study aims to determine the ecological index and distribution pattern of seagrass in the Banda Sea Aquatic Tourism Park (TWP). The method used is a line transect with a quadrant size of 50 cm x 50 cm that is placed perpendicular to the shoreline. The results showed that the seagrass diversity index at the study site consisted of 7 types of seagrass, namely Thalassia hemprichii, Enhalus acoroides, Cymodocea rotundata, Cymodocea serrulata, Halodule uninervis, Halophila ovalis, and Syringodium isoetifilium. The diversity index is categorized as moderate with a value of H' = 0.01-0.05, and a uniformity value of 0.71 has a high uniformity, which means that the number of individual species from one species to another is not much different from a stable environmental condition. The distribution pattern of seagrass with Id 1 is a grouped category. The physicochemical parameters obtained were in accordance with the growth of seagrass life.Keywords: Banda sea, Distribution pattern, Diversity, Dominance, Seagrass, Uniformity
