Abstract

The skeleton of deposited coral species Porites lutea can provide information to determine the life growth rate of the coral that can be seen on its annual bands. The coral sampling was carried out by using pneumatic drill and then it was analyzed to determine the direction, age, and growth rates of the coral, using X-ray. Result of the research showed that the growth rate of Porites lutea coral in northern station (windward) was in ranged of 0.60 – 2.50 cm/year while the average growth rate was 1.44 cm/year, and in the southern station (leeward) was in ranged of 0.50 – 2.20 cm/year while its average growth rate was 1.21 cm/year. The growth rate of Porites lutea both located north station (winward) and the south station (leeward) showed no significant difference.

Abstract

Terumbu karang merupakan ekosistem yang sangat unik dengan berbagai macam bentuk pertumbuhan. Banyak bintang laut jenis Linckia laevigata ditemukan berasosiasi dengan terumbu karang. Penelitian ini dilaksanakan pada bulan Januari-Februari tahun 2014 berlokasi di perairan Pulau Tunda, Kabupaten Serang, Provinsi Banten. Penilaian kondisi terumbu karang dan bintang laut ditentukan dengan metode Line Intercept Transect (LIT) dan kelimpahan bintang laut yang diterumbu karang ditentukan dengan metode Belt Transect. Parameter kualitas perairan pada seluruh lokasi pengambilan sampel masih sesuai dengan kehidupan terumbu karang dan bintang laut. Hasil penelitian menunjukkan bahwa kondisi terumbu karang pada perairan P. Tunda tergolong kategori baik, dengan tutupan karang hidup antara 54,95-73,00%. Bentuk pertumbuhan di dominasi oleh kelompok coral massif dan coral foliose. Kelimpahan bintang laut biru jenis L. laevigata yang ditemukan di perairan P. Tunda adalah 8-45 ind/100 m2. Asosiasi ini terjadi antara terumbu karang danbintang laut jenis L. laevigata yang merupakan asosiasi saling menguntungkan (mutualisme).

Abstract

Mangroves forests have adapted themselves from exposure to strong waves with high salinity. Mangroves grow on mud flats flooded with sea water or brackish water during high tide or flooded throughout the day. Kukupang village is one of the capital of the District of Jouronga Islands are located in the South Halmahera in North Maluku province. Mangrove ecosystem has grown Kukupang village life along the coast with an area of approximately 65 hectares with the condition is still very natural growth. The research was conducted in October-November 2014 Location of the study took place in mangrove ecosystem Kukupang Village District of Joronga Islands, South Halmahera in North Maluku. Transect method of determining the station square and performed by stratified random method. Data retrieval is divided into three stations measuring 10 x 10 m for trees, 5 mx 5 m for the stake, 1 x 1 m for the nursery, where elucidation of the sampling stations are divided into three stations. Based on the results of the study are six mangrove species found are: Rhizopora apiculata, Avicennia marina, Rhizophora mucronata, Sonneratia alba, Brugueraea gymnorrhiza, Ceriops tagal. Distribution pattern associated mangrove ecosystem, and the highest level of density is the type of mangrove species Rhizophora apiculata, the condition of the substrate at the location of the dominant research dust.
