Abstract

Kabupaten Purworejo merupakan daerah yang rawan terhadap bencana tsunami. Penelitian ini bertujuan untuk menetahui keanekaragaman vegetasi sebagai s,uatu upaya mitigasi tsunami di Kabupaten Purworejo, Jawa Tengah. Penelitian dilakukan pada bulan Agustus-September 2016 di kawasan pantai dan pesisir Desa Gedangan, Desa Jatikontal, dan Desa Ngentak. Pada kawasan pantai di Kabupaten Purworejo terdapat 16 famili dengan 18 jenis tumbuhan dengan jenis tumbuhan yang berpotensi untuk mitigasi tsunami adalah Casuarina equisetifolia, Terminalia catappa, dan Hibiscus tiliaceus. Pada kawasan pesisir di Kabupaten Purworejo terdapat vegetasi mangrove yang terdiri dari 6 famili dengan 8 jenis tumbuhan dengan jenis tumbuhan yang berpotensi dalam mitigasi tsunami adalah Rhizophora mucronata, R.stylosa, Sonneratia alba, S.caseolaris, and Nypa fruticans.Purworejo coastal area laid down in the critical area on nature disaster like tsunami. The aim of this research is determine of  biodiversity vegetation as an efforts of tsunami mitigation in Purworejo coastal area, Central Java. This research conducted at August-September 2016 in beach and coastal area of Purworejo Regency, Central Java. It was three location including Gedangan Village, Jatikontal Village, and Ngentak Village. This research obtained that beach area of Purworejo Regency consist of 16 family and 18 plant species with the potencial species for tsunami mitigation are Casuarina equisetifolia, Terminalia catappa, and Hibiscus tiliaceus. The coastal area of Purworejo Regency are habitat of mangrove vegetation consist of 6 family and 8 plant species with the potencial species for tsunami mitigation are Rhizophora mucronata, R.stylosa, Sonneratia alba, S.caseolaris, and Nypa fruticans.

Abstract

Mangrove is a unique ecosystem and has an important function ecologically, socio-economically, and education. The area of mangroves in Purworejo Regency is decreasing due to logging, settlement, ponds, and agriculture. Reduced mangrove stands will affect the existence of various fauna associated with it. Therefore it is done in August-September 2016 to know the diversity of the fiddler crabs in the mangrove area Purworejo District, Central Java. There are three stations, namely dense mangroves (Gedangan Village), medium mangroves (Jatikontal Village), and rare mangroves (Ngentak Village). From the research, there were 7 types of fiddler crab, Uca annulipes, U. crassipes, U. paradussumieri, U. rosea, U. tetragonon, U. vocans, and U. vomeris. The index of fiddler crab diversity in the mangrove area of Purworejo Regency, Central Java at station 1 (1.67) and station 2 (1.90) is moderate. The fiddler crab biodiversity index at station 3 (0.64) is low. Environmental conditions throughout the station are relatively good for mangrove life and fiddler crabs, ie temperature 26-30oC, pH 6-8, dissolved oxygen 3,5-6,6 mg / L, salinity 3-9 ppt, and sandy mud substrate. Vegetations of mangrove at station I are Rhizophora mucronata, Nypa fruticans, Sonneratia alba, and Hibiscus tiliaceus. Mangrove vegetation at station II is Sonneratia caseolaris, Rhizophora stylosa, N. fruticans, H. tiliaceus, and Morinda citrifolia. Vegetations of mangrove at station III are S. alba, S. caseolaris, N. fruticans, and R. mucronata. The density of mangrove vegetation is related to species abundance (density) of fiddler crabs.
