Abstract

Global warming is becoming increasingly apprehensive day by day, marked by the continued increase in levels of carbon dioxide (CO2) in nature. One of the efforts made to reduce the effects of global warming is biosequestration by empowering photosynthetic organisms, one of which is seagrass beds. This study aims to measure the density and percentage of seagrass cover, biomass value, and estimate carbon storage in seagrass biomass in the form of tissue at the top (leaves and upright stems) and tissue at the bottom (roots and rhizomes), as well as estimate carbon storage in sediments. Sampling was carried out using line transect and quadrant plot methods at each station. Calculation seagrass carbon storage using the Loss of Ignition (LOI) method at the Soil Chemistry Laboratory of the Pangkep State Agricultural Polytechnic, a total of 5 species of seagrass were found, namely Enhalus accoroides, Thalassia hemprichii, Halodule uninervis, Halopila ovalis, and Cymodocea rotundata. The average seagrass carbon storage on Badi Island is 18.92 gC/m2, or 0.189 MgC/ha. The species that act as the largest contributor to carbon storage are Cymodocea rotundata, namely 35.44 gC/m2, and Halopila ovalis, which acts as the lowest contributor to carbon storage, namely 1.92 gC/m2. The average seagrass carbon storage at the bottom of the substrate was three times greater than that at the top of the substrate, namely 14.10 gC/m2 at the bottom and 4.82 gC/m2 at the top. The average carbon storage in sediments is 10.98 gC/m2, or 0.109 MgC/ha.

Abstract

Ekosistem mangrove mempunyai kemampuan yang sangat efektif dalam mengurangi konsentrasi gas karbon dioksida (CO2) di alam. Estimasi stok karbon dapat dilakukan menggunakan teknologi penginderaan jauh yang mengacu pada indeks vegetasi dari suatu area. Penelitian ini dilaksanakan pada bulan Maret sampai Desember 2020 di Pulau Nunukan, Kabupaten Nunukan, Kalimantan Utara. Penelitian ini bertujuan untuk mengestimasi stok karbon permukaan (Above Ground Carbon) di Pulau Nunukan menggunakan citra Landsat-8 dan pengukuran in situ. Pengukuran nilai cadangan karbon di lapangan dengan menggunakan persamaan alometrik yang dihitung berdasarkan jenis vegetasi. Penggunaan citra Landsat-8 OLI dilakukan setelah pra-processing dengan koreksi geometrik dan radiometrik. Selanjutnya citra Landsat-8 OLI dilakukan klasifikasi unsupervised untuk menentukan batas wilayah sebaran mangrove, lalu ditransformasi ke persamaan Normalized Difference Vegetation Index (NDVI). Nilai NDVI dengan nilai stok karbon pada setiap titik sampel diuji dengan 3 jenis regresi. Dari 3 jenis uji regresi nilai R2 tertinggi ditetapkan sebagai persamaan untuk membangun model estimasi stok karbon permukaan. Dua jenis model estimasi stok karbon yang dibangun, yaitu model yang menggunakan seluruh jenis yang teridentifikasi sebagai sampel, dan model yang hanya menggunakan jenis dominan yang ditemukan pada wilayah kajian. Jenis mangrove yang mendominasi di Pulau Nunukan yaitu Rhizophora apiculata, sehingga jenis tersebut digunakan sebagai sampel dalam model estimasi stok karbon jenis dominan. Nilai R2 yang tertinggi dari persaaman regresi yang digunakan untuk mengestimasi stok karbon yaitu persamaan regresi kuadratik. Sehingga persamaan regresi kuadratik digunakan sebagai dasar model estimasi cadangan karbon. Nilai estimasi stok karbon permukaan (C) yang menggunakan model estimasi stok karbon seluruh jenis adalah 6.401.988,95 ton, sedangkan nilai estimasi stok karbon untuk model estimasi stok karbon jenis dominan adalah 5.616.404,46 ton.

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.

Abstract

Mangroves have numerous ecological functions as well as economical values. In order to achieve successful of mangrove restoration and regain its functions, understanding on the factors affecting the establishment of mangroves are required. This study examined the characteristics of physico-chemical factors from three compartments (sediment, interstitial and seawater) that associated with different mangrove densities in Ampallas, District of Mamuju, West Sulawesi. The Principal Component Analysis and Spearman correlation analysis showed that high densities of adult and seedling mangroves strongly correlated to higher organic contents, dissolved oxygen of interstitial water, seawater salinities and lesser pH of sediments, seawater and interstitial. The reverse conditions applied for the less mangrove densities and control site that had no mangrove. In most cases, there were reciprocal relationships amongst the studied variables.Keywords: chemical-physical factors, density, mangroves.

Abstract

The high level of human activity in coastal areas has had an impact on seagrass beds. The advancement of satellite imaging technology makes monitoring seaweed conditions even easier. The purpose of this study was to identify the spectral reflectance patterns of different seagrass cover levels and make it the basis for mapping the seagrass condition on Barranglompo Island. Based on google earth has been determined 4 sampling stations that represent the spread of seagrass on Barranglompo Island. Each station is divided into 4 sub-stations from land to sea. Sampling of seagrass cover was carried out by the McKenzie (2003) method modified by close sampling, to 30 x 30 square meters following the spatial resolution of Landsat image 8. Each observation point was estimated the percentage of seagrass cover and the dominant species. Digital seagrass pixel extraction is performed from band 1 to 7 landsat 8 according to point position in the field and then grouped by cover class and condition. Seagrasses found in Barranglampo Island are 8 species: Enhalus acoroides, Thalassia hemprichii, Halophila ovalis, Cymodocea rotundata, Cymodocea serulata, Halodule uninervis, Halodule pinifolia and Syringodium isoetifolium. In general, Enhalus acoroides and Thalassia hemprichii have higher closure than other seagrass species. The spectral reflection of seagrass landscape imagery 8 OLI channel 1 - 7 is good enough to show the seagrass condition in bad category, good enough, and good. Spectral reflection of the seagrass has a peak on the green channel. The worse the seagrass condition the higher the spectral reflection. Seagrass with bad conditions has a low cover so that other substrates such as sand will contribute to the spectral value recorded by satellite sensors. This result will facilitate mapping of seagrass condition on small islands by using Landsat 8 OLI image.Keywords: seagrass condition, spectral reflection, landsat 8, South Sulawesi

Abstract

Ekosistem padang lamun merupakan ekosistem yang umum ditemukan di Kepulauan Spermonde, salah satunya adalah Gusung Bonebatang. Lamun mempunyai kemampuan menyerap karbon untuk proses fotosintesis sehingga berpotensi dalam  mitigasi perubahan iklim.  Penelitian dilakukan pada bulan Agustus 2017 untuk membandingkan penyerapan karbon oleh jenis Thalassia hemprichii  pada beberapa kedalaman perairan. Sampel lamun diambil pada daerah subtidal, kemudian daun lamun dibersihkan dari sedimen dan epifit. Metode perubahan oksigen digunakan untuk mengestimasi serapan karbon. Sebanyak 1 tunas T. hemprichii diinkubasi menggunakan botol kaca bening 70 ml. Inkubasi dilakukan pada jam 09.00-12.00 WITA pada kedalaman 50, 100, 150, 200 dan 250 cm dengan masing-masing 5 kali ulangan setiap kedalaman. Sebelum inkubasi, dilakukan pengukuran konsentrasi oksigen terlarut di perairan sebagai kandungan oksigen awal. Pengukuran oksigen di dalam botol bening kembali dilakukan setelah inkubasi. Selain oksigen terlarut, dilakukan juga pengukuran konsentrasi bikarbonat pada awal dan akhir inkubasi. Sebagai kontrol, inkubasi juga dilakukan pada air laut (mengandung fitoplankton) dengan 5 kali ulangan. Daun lamun yang telah digunakan untuk pengamatan serapan karbon diukur luasnya dengan cara men-scan daun lamun dan dianalisis menggunakan software Imaje-J. Selanjutnya dilakukan pengeringan menggunakan oven dan ditimbang untuk mengetahui biomassa keringnya. Hasil penelitian menunjukkan bahwa serapan karbon per tunas berkisar antara 0,928-1,476 mgCO2/tunas/jam, per biomassa berkisar 10,647-25,745 mgCO2/gbk/jam, dan per luas daun berkisar 0,010-0,024 mgCO2/cm2/jam. Serapan karbon tertinggi didapatkan pada kedalaman 200 cm, baik serapan karbon per tunas, biomass maupun luas daun.

Abstract

Seagrass has many functions and values, including as carbon sink. However, to estimate carbon in seagrass, it involves seagrass biomass harvesting which is laborious, costly, and destructive. This study aimed to find out the relationship between seagrass Thalassia hemprichii percent cover with their biomass which will provide alternative method for biomass estimation leading to an efficient, less cost and less destructive method for seagrass carbon stock estimation. Seagrass were sampled in Bonebatang island, South Sulawesi, and estimated their percent cover following SeagrassWatch Method from different seagrass condition and sediment type, as well as harvested for their biomass. In the lab, seagrass biomass was dried. Data was analyzed by using simple regression analysis. Results showed that there is a relatively strong relationship between percent cover and the belowground, aboveground and total biomass (R2 = 0.70; 0,81 and 8,3, respectively). Seagrass percent cover (seagrass health status, i.e. healthy, moderate and poor) also resulted a relatively strong influence on total seagrass biomass (R2>50%). However, apart from segarss percent cover, some other parameters are needed to be taken into consideration, such as seagrass densities and seagrass morphologies

Abstract

Seagrass distribution is influenced by many factors, including sediment characteristics. This study aims to determine the distribution of seagrass based on their sediment characteristics. Observations and sampling were carried out in the waters of the Puntondo Bay, Takalar Regency. This study observed the cover and density of seagrass species, water depth, water transparency, sediment’s total organic matter and size of sediment grains. There were five species of seagrass found in the area, namely Enhalus acoroides, Thalassia hemprichii, Cymodocea rotundata, Halophila ovalis and Syringodium isoetifolium with sediment types of medium sand and coarse sand. Results of the regression analysis showed that the relationship between sediment particle size and seagrass density with the  highest coeficient determination (R2=0,3346) was in seagrass Cymodocea rotundata, whereas the lowest was in  Syringodium isoetifolium. Keywords: Seagrass, Puntondo, aters, Sediment grain size, Enhalus acoroides, Thalassia hemprichii, Cymodocea rotundata, Halophila ovalis, Syringodium isoetifolium.
