Abstract

 Lamun merupakan tumbuhan tingkat tinggi yang hidup di laut dangkal. Sebagai tumbuhan, lamun berperansebagai produser primer yang memberikan kontribusi bagi biota laut maupun ekosistem lainnya. Hasil produksiprimer dari lamun akan masuk ke beberapa kompartemen. Namun berapa besar aliran produksi tersebut ke tiapkompartemen masih menjadi pertanyaan. Penelitian bertujuan untuk melihat berapa besar hasil produksi daunlamun yang dialirkan ke kompartemen lain. Penelitian dilakukan di Pulau Barranglompo Makassar selama 4periode yang mewaikili musim hujan, peralihan I, musim kemarau dan peralihan II. Penelitian dilakukanmelalui beberapa tahap, yaitu (1) mengestimasi produktivitas daun lamun, (2) mengestimasi stok karbon daunlamun, (3) mengestimasi besarnya grazing daun lamun oleh bulu babi dan herbivora lain, (4) mengestimasibesarnya produksi serasah daun lamun, baik yang tenggelam di dasar maupun yang terbawa keluar dariekosistem lamun. Hasil penelitian menujukkan total karbon yang dialirkan ke kompartemen lain mencapai2,20% dari stok karbon daun atau setara 81,8% dari produktivitas daun. Aliran produksi melalui serasah yangmelayang sebesar 0,59% dari stok karbon (setara 22,0% dari produktivitas daun), serasah tenggelam 1,36% daristok karbon (setara 50,6% dari produktivitas daun), grazing bulu babi 0,04% dari stok karbon (setara 1,4% dariproduktivitas daun) dan grazing oleh herbivora lain 0,21% dari stok karbon (setara 7,9% dari produktivitasdaun). Dalam konteks aliran produksi, hasil produksi primer lamun paling banyak berkontribusi dalam ekosistemlamun sendiri sebagai serasah, bisa dimanfaatkan oleh detritivore sebagai makanan, terdekomposisi sebagaiunsur hara, atau terkubur sebagai cadangan karbon. Hanya sebagian kecil produksi primer dimanfaatkan secaralangsung oleh herbivora.Kata kunci : produktivitas daun lamun, aliran produksi daun lamun, grazing lamun, serasah lamun

Abstract

The existence of mangrove in coast areas have both ecologic and physical important functions.  Mangrove is a high productive ecosystem. Litters from fallen leaves and twigs are organic sources for macrozoobenthic life.  The aim of this research was to determine the response of macrozoobenthics on total organic matter content and other chemical-physico characters of sediments due to differences in mangrove conditions. This research was conducted from May to September 2016 in Sub-district of Ampallas, Distric of Mamuju, Province of West Sulawesi, Indonesia. Sediments in 20 cm2 transects were collected using small shovel to obtain the macrozoobenthic samples. The sediments contained macrozoobenthics were sieved using a 1 mm mesh size sieve net. Four sampling sites were chosen, each to represent areas with no mangroves, low, medium, and high densities.  The total of organic matter samples were collected using 2 inch diameter of PVC pipe cores, which were analyzed further using Loss by Ignition method.  Besides total of organic matter, several parameters (i.e. redox potential, sediment pH, salinity, temperature, and dissolved oxygen) were measured.  The results showed that gastropods dominated the existed macrozoobenthics.  Gastropods and oligochaete lived in greater amounts in high mangrove density site with higher organic matter content and fine substrate.Keywords: mangroves, macrozoobenthics, organic matter, Distric of Mamuju

Abstract

Coral reefs are organisms that live on the bottom of the waters and are in the form of limestone (CaCO3) which is strong against sea waves so that it can prevent coastal erosion and is also a place for various types of animals associated with coral reef ecosystems that utilize coral polyps. as his food. Mega-benthos are biota / organisms with a size of more than 1 cm that live on or in the seabed, including the sticking, creeping and burrowing biota that is visible with the camera. The research was conducted using the Line Intercept Transect Method and the Benthos Reef Check Method. The results showed that the highest percentage of live coral cover was found on Badi Island 71.46% (Good coral condition category), the moderate coral condition category was represented by Kapoposang Island (46.02%) and the bad coral condition category was represented by Ballanglompo Island ( 7.92%). The highest diversity of species (H ') Mega-benthos is at station 3 (Badi Island) with the value of H' = 2.528 while the lowest is at station IV (Lumu-lumu Island) with the value of H '= 0.6365. So that the category of the megabenthos species diversity index in the research location can be said to be in the low to moderate category.
