Abstract

ABSTRAKAnimal fouling merupakan organisme multisel besar dan berbeda yang terlihat oleh mata manusia seperti teritip, cacing tabung, atau daun alga dan sebagainya yang bersifat merusak. Animal fouling menjadi perhatian yang serius untuk struktur-struktur buatan yang berada di wilayah laut atau pantai dimana penempelan dari fouling pada permukaan struktur (substrat) dapat mempengaruhi berat mati struktur dan kecepatan laju hidrodinamik pada kapal laut, bahkan bisa berpengaruh pada bangunan seperti dermaga. Penelitian ini bertujuan untuk menghitung komposisi jenis, kepadatan, keanekaragaman dan mengukur parameter kualitas air di Pualu Harapan. Pengambilan data fouling dilakukan dengan menggunakan frame 20 x 54 cm. Pengamatan dilakukan sebanyak 2 stasiun, dimana setiap stasiun terdiri dari 20 substasiun. Dari hasil pengamatan didapatkan 3 kelas fouling, yaitu kelas bivalvia, thecostraca dan gastropda. Pada dermaga beton di kedua stasiun ditemukan 3 kelas fouling. Kelas bivalvia lebih mondominasi yaitu 99%, sementara kelas thecostraca ditemukan 0.38% dan kelas gastropoda 0.37%. Kerapatan dari kelas bivalvia ditemukan dengan rata-rata kepadatan 50173 ind/m², sementara kelas thecostraca 194 ind/m² dan kelas gastropoda 189 ind/m². Keanekaragaman pada stasiun 1 dan stasiun 2 menunjukkan nilai indeks keanekaragaman (H’) dengan nilai indeks 2,0, yang berarti tingkat keanekaragaman fouling pada masing-masing stasiun masuk kategori rendah. Hasil pengukuran kualitas air yang dilakukan di lokasi praktik ditemukan suhu  31.4 ⁰C - 31.8 ⁰C, salinitas 25 ⁰/ₒₒ -  30 ⁰/ₒₒ dan pH yang ditemukan yaitu 6. pH ini merupakan masih batas toleransi dari kehidupan fouling.Kata Kunci : Animal Fouling; Komposisi Jenis; Kepadatan; Keanekaragaman; Parameter Kualitas Air.ABSTRACTAnimal fouling is a large and different multicellular organism visible to the human eye such as barnacles, tube worms, or algae leaves and so on that are destructive. Animal fouling is a serious concern for artificial structures located in marine or coastal areas where the attachment of fouling to the surface of the structure (substrate) can affect the dead weight of the structure and the speed of hydrodynamic rates on ships, and can even affect buildings such as docks. This data collection aims to calculate the type composition, density, diversity and measure water quality parameters in Pualu Harapan. Fouling data collection is carried out using a 20 x 54 cm frame. Observations were made as many as 2 stations, where each station consisted of 20 substations. From the observations, 3 classes of fouling were obtained, namely the bivalve class, thecostraca and gastropda. On the concrete piers at both stations found 3 classes of fouling. The bivalve class is more dominant at 99%, while the thecostraca class is found to be 0.38% and the gastropod class is 0.37%. The density of the bivalve class was found with an average density of 50173 ind/m², while the thecostraca class was 194 ind/m² and the gastropod class was 189 ind/m². diversity at station 1 and station 2 shows a diversity index value (H') with an index value of 2.0, which means the level of fouling diversity at each station is in the low category. The results of water quality measurements carried out at the practice site found temperatures of 31.4 ⁰C - 31.8 ⁰C, salinity 25 ⁰ / ₒₒ - 30 ⁰ / ₒₒ and pH found to be 6. This pH is still the tolerance limit of fouling lifeKeywords : Animal Fouling; Density; Diversity; Type Composition; Water Quality Parameters.

Abstract

ABSTRACTSeagrass beds have an important role as the main source of primary productivity or organic matter producers, habitat for various biota, nursery grounds, spawning grounds, food sources for rare biota, and support for the diversity of marine biota species, as well as the economic value of seagrass ecosystem services. This study aims to determine the ecological index and distribution pattern of seagrass in the Banda Sea Aquatic Tourism Park (TWP). The method used is a line transect with a quadrant size of 50 cm x 50 cm that is placed perpendicular to the shoreline. The results showed that the seagrass diversity index at the study site consisted of 7 types of seagrass, namely Thalassia hemprichii, Enhalus acoroides, Cymodocea rotundata, Cymodocea serrulata, Halodule uninervis, Halophila ovalis, and Syringodium isoetifilium. The diversity index is categorized as moderate with a value of H' = 0.01-0.05, and a uniformity value of 0.71 has a high uniformity, which means that the number of individual species from one species to another is not much different from a stable environmental condition. The distribution pattern of seagrass with Id 1 is a grouped category. The physicochemical parameters obtained were in accordance with the growth of seagrass life.Keywords: Banda sea, Distribution pattern, Diversity, Dominance, Seagrass, Uniformity

Abstract

ABSTRACTSalinity is the total concentration of ions found in water. Salinity is important for the survival of organisms. Almost all marine organisms can only live in areas that have small changes in salinity. The aim of this research is to determine the distribution pattern of salinity in Spermonde waters in 2022 and to find out a comparative picture of the salinity distribution pattern on Kapoposang Island, Samatellu Lompo Island, Kuninggareng Lompo Island and Lanyukang Island in Spermonde waters in 2022. This research was conducted from August to October 2023 in Hasanuddin University Makassar, Makassar City, South Sulawesi Province. Research was conducted at the Indraja Laboratory, Faculty of Marine and Fisheries Sciences. The data used was satellite image data, namely CMEMS satellite image. The pattern of salinity distribution in Spermonde Waters with an average value of 34.04 ppt is the highest salinity in August, and for the average value of salinity distribution of 32.52 ppt is in January. The comparison pattern of salinity distribution in 2022 on Kapoposang Island, Lanyukang Island, and Samatellu Lompo Island has the same average value, namely the lowest January and the highest August, except for Koninggarang Lompo Island the highest average value is in September and the lowest is in January.Keywords: Salinity, Kapoposang Island, Lanyukang Island, Koninggareng Lompo Island, Samatellu Lompo Island

Abstract

ABSTRACTOne of the parameters determining productivity in the sea is chlorophyll-a. The fertility level of chlorophyll-a is closely related to the concentration of chlorophyll-a. The higher the concentration of chlorophyll-a, the higher the water fertility level, conversely, if chlorophyll-a is low, the water fertility level will also be low. One factor influencing growth rate and chlorophyll-a production is temperature. This research aimed to determine the distribution of chlorophyll-a and sea surface temperature based on season in 2022 in the waters of Bone Bay using quantitative descriptive method and geographic information analysis (GIS) procedure in the form of analysis of Aqua MODIS remote sensing image data. The research results showed that the highest distribution of chlorophyll-a occurred in the east season with a concentration of 0.06-2.04 mg/m³, while the lowest distribution of chlorophyll-a occurred in the west season with a concentration of 0.07-1.76 mg/m³. Meanwhile, the highest intensity sea surface temperature distribution occurred in the west season, which was 28.76-37.09 °C and the lowest sea surface temperature distribution fell in the east season, which was 27.13-33.62 °C. Spatial temperature variability and sea surface chlorophyll-a can be used as information about potential areas for fishing grounds.Key words: chlorophyll-a distribution, sea surface temperature, Bone Bay, Aqua MODIS
