Abstract

The observation of dissolved oxygen level and Apparent Oxygen Utilization (AOU) in Lembeh Strait Waters was conducted in January, February, June and July 2016. The objective of this research is to know the condition of dissolved oxygen and Apparent Oxygen Utilization (AOU). The results of the analysis showed that dissolved oxygen levels in the surface layer and near the bottom ranged from 6.00-6.56 mg/l and 5.59-6.17 mg/l. Based on the values of temperature and salinity obtained from this study, solubility, oxygen saturation degree and AOU value at the surface layer were calculated. In the surface layer the AOU values are positive, ranging from 0.10-0.72 mg/l, while near the bottom, negative and positive AOU values were balanced, ranging from -0.23-0.42 mg/l. The concentration of dissolved oxygen in the Lembeh Strait waters has not shown negative impact on the aquatic environment and is still in accordance with sea water quality standards for marine biota.Keywords: Dissolved oxygen, apparent oxygen utilization (AOU), Lembeh Strait. ABSTRAK         Pengamatan kadar oksigen terlarut dan Apparent Oxygen Utilization (AOU) di Perairan Selat Lembeh dilaksanakan pada bulan Januari, Februari, Juni dan Juli 2016. Penelitian ini bertujuan untuk mengetahui kondisi oksigen terlarut dan Apparent Oxygen Utilization (AOU). Hasil analisa menunjukkan bahwa kadar oksigen terlarut di lapisan permukaan dan dekat dasar berkisar antara 6,00-6,56 mg/l dan 5,59-6,17 mg/l. Berdasarkan nilai suhu dan salinitas yang diperoleh dari penelitian ini telah dihitung daya larut, derajat kejenuhan oksigen dan nilai AOU pada lapisan permukaan. Di lapisan permukaan nilai AOU semuanya positip berkisar antara 0,10-0,72 mg/l dan di dekat dasar nilai AOU negatip dan positip berimbang, berkisar antara       -0,23-0,42 mg/l. Konsentrasi oksigen terlarut di perairan Selat Lembeh belum menunjukkan dampak negatip terhadap lingkungan perairan dan masih sesuai dengan baku mutu air laut untuk biota laut. Kata Kunci: Oksigen terlarut, apparent oxygen utilization (AOU), Selat Lembeh.

Abstract

ABSTRACT Distribution Temperature, Salinity and Dissolved Oxygen in Kema Waters, North Sulawesi. Distribution of temperature, salinity and dissolved oxygen in the water is very influential on the various aspects of the other parameters, such as chemical reactions and biological processes. Research on the conditions of temperature, salinity and dissolved oxygen in the Kema waters, North Sulawesi in April and May 2010. The results showed that temperature ranges from 28.2 to 32.5°C with an average of (30.1 ± 1.11°C), salinity between 28.0 to 33.0o/oo with an average of (31.7 ± 1.36o/oo) and dissolved oxygen between 3.46 to 6.25 ppm with an average of (4.73 ± 0.76 ppm). Distribution of values ​​of temperature, salinity and dissolved oxygen levels vary. Variations in temperature, salinity and dissolved oxygen in these waters was affercted by external factors including weather, wind and currents. Conditions of temperature, salinity and dissolved oxygen in this waters were still relatively normal and preferable for marine life.

Abstract

Research on the structure of seagrass communities in the waters of the island Mantehage was conducted in September 2010. The purpose of this study is to collect data and information on the structure of seagrass communities. Observations includes the identification seagrass species, measuring the number of individual/stand, cover percentage of each type/species on the transect. 6 types of seagrass found, i.e. Enhalus acoroides, Halophila ovalis, Thalassia hemprichii, Thalassodendron ciliatum, Cymodocea rotundata and Syringodium isoetifolium. Seagrass species composition and distribution varies at each location and is dominated by the presence of Thalassia hemprichii (48.14%) with coverage percentage ranges between 15.91% to 35.11%. Diversity index values ranged from 0.79 to 1.69 ; evenness index between 0.57 to 0.94 and the index of dominance between 0.20 to 0.56. In conclusion, the condition of seagrass meadows in Mantehage island is relatively good and can support marine life adequately.Keywords : Structure communities, seagrass, Mantehage Island

Abstract

ABSTRACT The study of water quality and macroalgae community in Jikumerasa coast, Buru Island, Maluku, was conducted in June 2014. This study aims to determine the water quality in terms of physico-chemical parameters and community structure of macroalgae. Physico-chemical parameters observed are the essential parameters for the livelihood of macroaelgae ecosystem such as temperature, salinity, water clarity, current, pH, dissolved oxygen, phosphate and nitrate. The result showed that water quality in these waters still within the water quality standard threshold for marine biota (KMLH, 2004) and still in the optimum range for growth of macroalgae. 21 species of macroalgae were found with varying density between 0.25 ind./m2-1.13 types ind./m2. The highest biomass were found in Gracilaria salocornia, which reached 1132.00 g/m2. Macroalgae diversity index (H ') were average, ranged from 2.716 to 2.978 and dominance index (D) were categorized as low, ranged from 0.0539 to 0.0697, while the index of uniformity (e) were ranged from 0.9754 to 0.9796, categorized as evenly distributed or stable. Keywords: Water quality, macroalgae, Community Structure.   ABSTRAK Studi tentang kualitas air dan komunitas makroalga di perairan pantai Jikumerasa, Pulau Buru, Maluku telah dilakukan pada bulan Juni 2014.
