“…Species composition tends to affect the sediment carbon stock at the MPA site, however this is not the case at the disturbed site. Although seagrass Enhalus acoroides is also dominant within the meadows (Rustam et al 2016), sediment carbon stock at disturbed site was measured lower than at the MPA site.…”

“…The main coastal ecosystems in the island include mangrove forests, seagrass meadows, and coral reefs. Rustam et al (2016) study estimated that seagrass cover in the island varies between 10-85% and the standing biomass stock has a storage of 1.04 ± 1.3 Mg C ha − 1 with seven seagrass species recorded: Enhalus acoroides, Thalassia hemprichii, Halophila ovalis, Cymodocea serrulata, Cymodocea rotundata, Halodule uninervis and Syringodium isoetifolium.…”

“…The islands are bordered with Mindanao (The Philippines) in the north, and Sulawesi Island in the south, and are surrounded by two oceans, Laut Sulawesi and Maluku (Undap et al 2019). Six seagrass species are recorded on this island, Enhalus acoroides, Thalassia hemprichii, Halophila ovalis, Cymodocea serrulata, Halodule uninervis and Syringodium isoetifolium (Rustam et al 2016).…”

“…This study Among the study sites, Nusa Lembongan as an MPA had the highest sediment carbon stock and OC content compared to the other two locations. The high OC content and carbon stock at the MPA site might be attributed to the composition of seagrass in the location, which is dominated by large-leaved seagrass, Enhalus acoroides (56.7%; Rustam et al 2016). Large-leaved seagrasses tend to have rhizomes and roots that are also larger and more persistent, penetrating deeper into sediment, making them more likely to be preserved in marine sediment (Lavery et al 2013;Kennedy et al 2022).…”

Seagrass meadows are an important component of coastal ecosystems globally, and they capture and store organic carbon in living biomass and sediments. Geographical estimates of blue carbon in seagrass habitats are regionally biased, with limited information from the Indo-Pacific region, including Indonesia. Seagrass extent in Indonesia is declining rapidly, and it has been suggested that Marine Protected Areas (MPAs) are an important instrument to support protection of seagrass ecosystems and its services. Thus, our study aimed to quantify and to compare sedimentary carbon stocks and sources of organic carbon in seagrass meadows located in undisturbed areas outside MPA, disturbed areas outside MPA, and within MPA in three small islands in Indonesia. The sediment carbon stocks ranged from 19.81 to 117.49 Mg C ha− 1, with the highest stock measured inside MPA (77.15 ± 1.38 Mg C ha− 1), followed by undisturbed outside MPA (36.08 Mg C ha− 1), and lowest stock at disturbed outside MPA (21.86 ± 0.31 Mg C ha− 1). The predominant source of organic carbon in disturbed meadows was from coastal POM (~ 36%), while in MPA and undisturbed site the main source was seagrass, with ~ 38% and ~ 60%, respectively. The results of this study highlight the influence of MPAs on conserving carbon stock in seagrass ecosystems and provide important information on the importance of MPA’s in avoiding emissions caused by remineralisation of sediment organic carbon following seagrass degradation.

“…Sebagai desa pesisir berbagai pengaruh yang terjadi di darat maupun di laut akan berimbas pada pesisir, salah satunya yakni kehadiran dari sampah plastik. Keberadaan sampah di laut berdampak buruk bagi ekosistem lamun dan sekitarnya [8,9]. Bakring selaku ketua kelompok nelayan lestari beserta 4 orang anggotanya telah membuat penahan sampah sederhana, yang terdiri dari jaring, tali, dan pelampung dan diletakkan di dekat daratan (Gambar 1).…”

Indonesia memiliki tantangan yang besar untuk mengatasi masalah sampah. 80% sampah di perairan berasal dari darat, yang berdampak pada terancamnya keanekaragaman hayati dan sumber daya di laut. Kegiatan pengabdian ini bertujuan untuk membina kelompok mitra sasaran dengan penguatan keterampilan softskill dan hardskill mengenai penanganan sampah di laut melalui pembuatan dan pengoperasian marine debris trap melalui modifikasi sero sehingga dapat meminimalisir jumlah sampah yang terekspos di laut dan mengurangi dampak yang ditimbulkannya. Mitra yang terlibat yaitu “kelompok nelayan lestari” menyediakan fasilitas alat tangkap sero yang akan dimodifikasi bentuknya menjadi sero marine debris trap, berfungsi menjebak ikan dan juga berfungsi sebagai alat penjebak sampah laut. Sero marine debris trap yang telah dirancang dan dioperasikan mampu menjebak sampah laut dengan kapasitas 800 g sampai 1 kg dalam waktu 1 (satu) minggu, sekaligus tetap dapat menjebak ikan. Sampah laut yang terjebak terdiri atas sampah anorganik dan organik. Sampah anorganik berupa botol plastik, kemasan minuman plastik, kaleng bekas, dan styrofoam. Sampah organik berupa serasah dari lamun. Botol plastik memiliki persentase sebesar 22% dari total sampah plastik yang ditemukan.

Perubahan iklim global yang semakin meningkat dapat menyebabkan kenaikan kadar karbondioksida pada atmosfer. Lamun dapat mengurangi kadar karbondioksida pada atmosfer dengan cara menyerap karbon anorganik melalui proses fotosintesis lamun dan menyimpannya dalam bentuk karbon organik dalam jangka waktu lama. Oleh karena itu penelitian ini bertujuan untuk mengetahui komposisi jenis, kerapatan, penutupan, indeks ekologi, biomassa, dan karbon pada vegetasi lamun di Pantai Prawean, Jepara. Penelitian ini menggunakan metode pengambilan data secara purposive sampling. Pendataan kondisi padang lamun mengacu pada metode LIPI 2014 dengan mendata penutupan, dan kerapatan lamun. Pengambilan sampel lamun menggunakan seagrass core secara acak. Sampel lamun diolah dengan metode Loss On Ignition (LOI) untuk mengetahui kadar karbon. Selanjutnya data kadar karbon dikonversikan berdasarkan nilai biomassa lamun. Jenis lamun yang ditemukan di Pantai Prawean berjumlah 5 jenis antara lain Cymodocea rotundata, Thalassia hemprichiii, Oceana serrulata, Enhalus acoroides dan Halodule uninervis. Kerapatan lamun di Pantai Prawean dapat mencapai 1717 individu/m2 pada stasiun 1 dan 780 individu/m2pada stasiun 2. Persentase penutupan lamun total di Pantai Prawean sebesar 39,20 % pada stasiun 1 dan 22,73 % pada stasiun 2. Indeks ekologi pada stasiun 1 memiliki keanekaragaman rendah, keseragaman rendah dan ada dominasi lamun. Sedangkan pada stasiun 2 memiliki keanekaragaman sedang, keseragaman sedang dan dominasi sedang. Total biomassa lamun pada stasiun 1 dan stasiun 2 sebesar 2970,01 g/m2 dan 1345,85 g/m2. Total estimasi kandungan karbon lamun pada stasiun 1 dan stasiun 2 sebesar 1000,61 gC/m2 dan 447,27 gC/m2. Global climate change can cause an increase in carbon dioxide levels in the atmosphere. Seagrass can reduce carbon dioxide levels in the atmosphere by absorbing inorganic carbon through the seagrass photosynthesis process and storing it in the form of organic carbon for a long time. Therefore, this study was conducted to determine species composition, density, cover, ecological index, biomass, and carbon in seagrass vegetation in Prawean Beach, Jepara. This research uses purposive sampling data collection method. Data collection on the condition of seagrass beds refers to the 2014 LIPI method by recording the cover and density of seagrass. Seagrass sampling used random seagrass cores. Seagrass samples were processed by the Loss On Ignition (LOI) method to determine the carbon content. Furthermore, the carbon content data is converted based on the value of seagrass biomass. There are 5 types of seagrass found on Prawean Beach, namely Cymodocea rotundata, Thalassia hemprichiii, Oceana serrulata, Enhalus acoroides and Halodule uninervis. The density of seagrass in Prawean Beach can reach 1717 individuals/m2 at station 1 and 780 individuals/m2 at station 2. The percentage of total seagrass cover in Prawean Beach is 39.20% at station 1 and 22.73% at station 2. station 1 has low diversity, low uniformity and there is a dominance of seagrass. While at station 2 has moderate diversity, moderate uniformity and moderate dominance. The total biomass of seagrass at station 1 and station 2 was 2970.01 g/m2 and 1345.85 g/m2. The total estimated carbon content of seagrass at station 1 and station 2 is 1000.61 gC/m2 and 447.27 gC/m2.
