Macroalgae is one of the marine biological resources that has a potential to be utilized further by humans. This research aims to study macroalgae diversity and utilization potency by humans in the coastal area of Tunda Island. The study was conducted at 4 stations using the belt transect method. Results of this study indicated that there were 15 species of macroalgae found that came from 3 macroalgae classes, they were chlorophyceae, phaeophyceae, and rhodophycea. Macroalgae species that are often found are Padina minor, Halimeda macroloba, and Gracilaria salicornia. The highest macroalgae diversity was found at station 3 with a value of 2.44. Based on the type of macroalgae found in the field there are several macroalgae species that can be utilized, and the lack of information causes the low macroalgae utilization by the local community. Keywords: Biodiversity, Gracilaria salicornia, Halimeda macroloba, macroalgae, Padina minor

Abstract. Teluk Bakau Village is one of the largest conservation areas of seagrass ecosystem located in Bintan Island. This research aim to study the distribution of species, seagrass coverage and seagrass density in Teluk Bakau Village. The research was conducted at two stations, Beralas Pasir Island and Teluk Bakau Village Beach. Seagrass data collections are computed using transect quadrat method. The results of this study show that there is total 8 species of seagrasses found in the conservation area of seagrass ecosystem in Teluk Bakau, namelu Enhalus acoroides, Thalassia hemprichii, Cymodocea rotundata, Cymodocea serulata, Halophila ovalis, Halophila minor, Syringodium isoetifolium and Halodule uninervis. The highest seagrass cover value was found at Beralas Pasir Island station about 47%, while in Teluk Bakau Village Beach station the seagrass coverage value was arround 29%. Based on these coverage value, the seagrass ecosystem in Teluk Bakau area fall in the category of medium conditon. The excistence of seagrass ecosystem in Teluk Bakau village is utilized by the community in small scale fisheries activity, therefore it is utmost important that its biodiversity and level of coverage are maintaned or even improved.Keywords: Bintan, conservation, coverage, seagrass, teluk bakau Abstrak.

Tidung Island is one of the islands in the Seribu Island area which has marine tourism destinations. To declare the achievement of SDGs no. 6 (Clean water and sanitation) and 14 (Life Below Water), then one of the community service activities (PPM) that can be done is cleaning garbage in the coastal areas. This activity aims to be directly involved in cleaning up garbage on Tidung Island. The method used was going directly to the field as well as conducting direct observations and interviews to find out the sources and types of existing waste and waste management that is already running. The result of this PPM activity is a clean beach on Tidung Island. This activity was carried out to get Tidung Island’s coast clean and healthy so that SDGs no. 6 and 14 can be reached. The results of community service activities show that the community is enthusiastic to carry out waste management independently and with related officers to create the Tidung Island area as marine tourism. --- Pulau Tidung adalah salah satu pulau di daerah Kepulauan Seribu yang memiliki destinasi wisata bahari. Dalam rangka mencanangkan capaian SDGs no. 6 (Clean water and sanitation) dan 14 (Life Below Water) maka salah satu kegiatan pengabdian pada masyarakat yang dapat dilakukan adalah pembersihan sampah di wilayah pesisir. Kegiatan ini bertujuan untuk terlibat langsung dalam membersihkan sampah di Pulau Tidung. Metode yang digunakan adalah turun langsung di lapangan sekaligus melakukan pengamatan langsung dan wawancara untuk mengetahui sumber dan macam sampah yang ada serta pengelolaan sampah yang sudah berjalan. Hasil berkegiatan PPM ini yaitu membersihkan pantai di Pulau Tidung. Kegiatan ini dilakukan untuk mendapatkan pantai Pulau Tidung yang bersih dan sehat sehing-ga dapat tercapainya SDGs no. 6 dan 14. Hasil kegiatan pengabdiam masyarakat menunjukkan masyarakat bersemangat untuk melakukan pengelolaan sampah secara mandiri maupun bersama petugas terkait untuk menciptakan kawasan Pulau Tidung sebagai wisata bahari.

Rhizophora apiculata merupakan jenis mangrove yang banyak digunakan sebagai obat tradisional. Potensi ini dihasilkan oleh kandungan metabolit sekunder yang dapat dipengaruhi oleh kondisi lingkungan, usia, dan beragam faktor lainnya. Penelitian ini bertujuan untuk menentukan pelarut terbaik ekstrak R. apiculate berdasarkan parameter toksisitas dan antibakteri. R. apiculata yang digunakan dalam penelitian ini berasal dari daerah Kuala Langsa dan Pulau Telaga Tujuh (Aceh Timur), dengan ukuran diameter pohon yang berbeda (2,4; 4,8; 5; 13; 23,3; & 26 cm). Ekstraksi dengan pelarut metanol 99,8% (MeOH) dan etanol 99,9% (EtOH) dilakukan dengan maserasi (3x24 jam), ekstraksi dengan pelarut akuades dilakukan dengan perebusan (15 menit pada suhu 85-90°C). Ekstraksi menggunakan perbandingan 10:1 (v/w) dengan 2 g serbuk simplisia dan 20 mL pelarut. Uji toksisitas dilakukan dengan metode brine shrimp lethality assay dan uji antibakteri menggunakan metode disk diffusion assay. Uji toksisitas menunjukkan ekstrak etanol memiliki nilai toksisitas tertinggi dengan nilai LC50 sebesar 26,879 μg/mL. Ekstrak akuades menghasilkan zona hambat tertinggi dengan nilai 11,37±0,85 mm pada bakteri Escherichia coli dan 17,67±1,19 mm pada bakteri Staphylococcus aureus. Hasil ANOVA dua arah menunjukkan pelarut berpengaruh nyata terhadap zona hambat bakteri (p<0,05), sementara diameter pohon tidak berpengaruh nyata (p<0,05). Ekstrak pelarut etanol menghasilkan nilai toksisitas tertinggi, sedangkan ekstrak pelarut akuades menghasilkan zona hambat terbesar.

Research on microplastic (MP) accumulation in marine organisms' tissue have been widely conducted, as well as research on microplastic biodegradation by microbial organisms from the environment.Agelas coniferasponge is proven to accumulate MP in its tissue as well as having bacteria as symbiotic organism. This research aims to screen and study biodegradation activities ofA. coniferasymbiotic bacteria on MP polymers, alsoto identify the species of those bacteria isolates. Bacterial Isolation ofA. coniferasponge tissue was using Zobell 2216E agar media. Screening and biodegradation assay of the bacteria isolates was conducted on Marine Salt Media agar that was added with 0,5 g of MP polymers, using Kroc-Boral method. Diameter of clear (bacterial growth) zone surrounding Kroc-Boral indicated the biodegradation activity of the bacterial isolates. Statistical analysis on the activity was using Two Way ANOVA. Results showed that there were 9 bacterial isolates of 53 that could degrade several MP polymers, with different activities (ANOVA, p value 0.05). High and low-density polymers (Linear- Low Density PolyEthylene/ LLDPE, Polyethylene/PE, and Polyvinyl Chloride/ PVC) were found to be degraded by all 9 isolates. Meanwhile, Polyethylen Taraphtalene (PET) and Polystyrene (PS) only degraded by 8 and 3 isolates, respectively. There are only 5 isolates that have high biodegradation index (1.5) on different polymers, which mostly on PET polymer. Isolate Ac8MP found to be the most bacteria that have degradation index on all polymers more than 1.This research proves that symbiotic bacteria could have a biodegradation mechanism on MP polymers that accumulates by sponge-host. However, further study needs to be done to understand the mechanisms and effectiveness of sponge-bacterial biodegradation activity.
