“…kematian dari individu makroalga tersebut kemudian akan menjadi salah satu penghasil bahan organik di perairan (Riniatsih et al 2018). Fenomena tersebut dijelaskan oleh Srimariana et al (2020) perairan dengan substrat berkarang memiliki kemungkinan untuk terdapatnya lebih banyak variasi makroalga pada kawasan tersebut karena struktur makroalga menjadi kokoh serta pada pecahan karang umumnya terkandung kalsium karbonat untuk pertumbuhan struktur beberapa jenis makroalga, sedangkan pada Pulau Panjang memiliki substrat pasir berkarang dan Pantai Prawean memiliki substrat pasir berlumpur. Penutupan makroalga yang ditemukan pada kedua lokasi penelitian mendapatkan hasil yang disajikan pada Tabel 3.…”

Ekosistem lamun memegang peranan penting sebagai produsen primer, tempat pemijahan, tempat tinggal biota perangkap sedimen, serta penahan erosi. Kondisi kesehatan lamun menjadi penting berdasarkan perannya tersebut. Indeks kesehatan lamun dapat memberikan informasi yang merepresentasikan kondisi ekosistem lamun yang meliputi komposisi spesies lamun, tutupan lamun, tutupan makroalga, tutupan epifit, dan intensitas cahaya perairan. Tujuan dilakukannya penelitian ini sebagai informasi perbandingan kondisi indeks kesehatan lamun yang ada pada perairan Pantai Prawean dengan Pulau Panjang. Teknik sampling pada penelitian ini dilakukan dengan metode transek garis yang pada pelaksanaannya menggunakan transek kuadran berukuran 50 x 50 cm yang dilakukan pada dua stasiun di setiap lokasinya dan terdapat tiga line transek pada setiap stasiunnya. Beberapa spesies lamun yang terlihat di lokasi adalah Enhalus acoroides, Oceana serrulata, Thalassia hemprichii, dan Cymodocea rotundata. Hasil dari penelitian ini yaitu nilai indeks kesehatan ekosistem lamun di Pulau Panjang adalah 0,62 dengan kategori sedang dan di Pantai Prawean adalah 0,5 dengan kategori buruk. The seagrass ecosystem plays an important role as a primary producer, a spawning ground, a habitat for sediment-trapping biota, and erosion control. The health condition of seagrass is crucial based on its roles. The seagrass health index can provide information representing the condition of the seagrass ecosystem in the area. The purpose of this study is to compare the seagrass health index values between the waters of Pantai Prawean and Pulau Panjang. The sampling technique in this study was conducted using the LIPI line transect method, which used 50 x 50 cm quadrat transects at two stations in each location, and there were three line transects at each station. Some seagrass species observed at the location were Enhalus acoroides, Oceana serrulata, Thalassia hemprichii, and Cymodocea rotundata. The required variable data for calculating the seagrass health index value are the number of seagrass species, seagrass coverage, macroalgae coverage, epiphyte coverage, and water clarity. The results of this study showed that the seagrass ecological quality index (SEQI) in Pulau Panjang was 0.62 with a moderate category, while in Pantai Prawean, it was 0.5 with a poor category.

This study aims to identify macroalgae scattered in Walakiri waters. The method used in this study was to explore the entire coast of Walakiri. The samples which were then identified visually and morphologically include: color, thallus shape, serrations on the stems of each macroalgae sample and then matched to AlgaeBase: http://www.algaebase.org. The results showed that there were 3 classes of macroalgae with a total of 10 species including red algae (Eucheuma cottonii, Eucheuma spinosum, Achanthopora spicifera), brown algae (Padina australis, Sargassum vulgare, Sargassum cristaefolium, Sargassum polycystum), and green algae (Ulva reticulata, Halimeda micronesica, Codium Fragile). In addition, the water quality of Walakiri is good for macroalgae growth.

Batu Layar coastal area provides an optimum environment for the diversity of coastal biota in the form of corals, crustaceans, molluscs, echinoderms and macroalgae. Macroalgae are plantlike marine biota that are large in size. Based on taxonomy, macroalgae are included in the Thallophyta group because their bodies are thallus. The purpose of this study is to evaluate the abundance of macroalgae in Batu Layar Coastal areas to be used as primary data for further research. This research is located at Batu Layar Coast using the Transect method. The number of transects used is 4 transects with the length of each transect is 50 m. On each transect, 5 stations were taken. Samples of each different macroalgae species at each station were taken for the purpose of morphological identification. Macroalgae identification is presented in the form of descriptive analysis and graphs in the presentation of diversity, evenness, and abundance. The results of the identification of macroalgae in research at Batu Layar Coast as a whole found that there were 24 species of macroalgae consisting of 11 species of Chlorophyta, 8 species of Rhodophyta and 5 species of Phaeophyta. Dominant species on the shoreline are Chlorophyta, in the middle of the transect most of algae are the Phaeophyta and dominant species farthest from the shore are Rhodophyta. The conclusion is the most abundant macroalgae species is Gelidium latifolium from Rhodophyta division with number of abundance is 4.58 individuals/m2.
