“…Planting seedlings is a cost-efficient method for large-scale seagrass meadow restoration. However, the main limitation of seedling establishment programs is the low seedling survival rate observed due to unsuitability of environmental conditions (Ambo-Rappe et al, 2019). Therefore, the study of seedling trait responses under different environmental conditions, such as temperature or nutrient enrichment, on this early-life phase may enhance future restoration and conservation management plans of these threatened ecosystems.…”

Morphological and Physiological Responses of Enhalus acoroides Seedlings Under Varying Temperature and Nutrient Treatment

Seagrass meadows are declining globally. In Indonesia, 75% loss has been reported in the last 5 years. The decrease of the seagrass area is influenced by the simultaneous occurrence of many factors at the local and global scale, including nutrient enrichment and climate change. This study aims to find out how increasing temperature and nutrient enrichment affect the morphological, biochemical and physiological responses of Enhalus acoroides in the seedling phase, which has not previously been studied. To achieve these aims, a laboratory experiment of combined temperature and nutrient treatments was conducted using recently-germinated seedlings of E. acoroides. The results showed that the seedlings were tolerant to an extended exposure to the current ambient maximum temperature. Under higher temperature treatment, the seedlings were observed to increase in aboveground size traits (e.g., number of leaves, leaf length, biomass, and leaf area), as well as in belowground traits, such as root length. The results in this study also showed that the initial seed size matters for morphological responses. On the contrary, nutrient responses of seedlings were practically absent, suggesting they could rely on internal reserves. Interaction between both factors was limited, with the exception of low temperature and high nutrient treatment, in which the AG:BG ratio and leaf elongation rate increased. Fluorescence parameters were not influenced by any of the water treatments. The results in this study suggest that E. acoroides seedlings rely energetically in the reserves within the seedling and that increasing temperature might result in faster seedling development, although no interactions with other organisms were tested. This is of importance when studying the resilience capacity of this species and when restoration attempts are planned, as a faster root development would provide a faster stabilization in the sediment and the survival of the whole plant.

“…Based on the information presented, it can be seen that the survival rate of seagrass seedlings in field has a decreasing trend. Another study stated that the downward trend also occurred in the process of planting seagrass seeds directly without going through the domestication process in laboratory [10], [12]. In this study, the survival rate of seedlings until the 4 th month, which is 20%, is higher than the survival rate of E. acoroides seedlings grown on rubble and coarse sand substrates [12].…”

“…One of the seagrasses that has a good level of adaptation is E. acoroides [11]. Another reason to use E. acoroides is the size of seed is large enough compared to other species in Indonesia, and this species is quite abundant [1], [10]. Seagrass seeds derived from the seedling process can be used as a solution in seagrass restoration by planting seagrass seeds in nature.…”

There has been a global decline in the area of seagrass ecosystems caused by the increasing number of human activities in coastal areas. It is suspected that the decline in the area of seagrass beds in Indonesia is 2%-5% per year. It takes an effort that can be used to restore the condition of seagrass beds. So far, efforts have been made to do seagrass transplants. There is a weakness in the transplant method, namely the reduction of seagrass stands in the origin (donor) area. Another effort that can be used is planting seagrass using seagrass seeds derived from seedlings. Seagrass seeds come from the seagrass, Enhalus acoroides, which is found throughout the year in the waters of Bintan Island. Furthermore, the seeds obtained will be sown for three months in the laboratory. Generally, the survival rate of seagrass seeds during the seedling process has a value of more than 90%, which is very good. Furthermore, the seeds produced from the nursery process are planted in the field. In this experimental study, 25 seedlings were planted. Seedlings were planted directly into the substrate at a depth of 10 cm (sprig method). During the four-month observation period, the survival rate declined to 20%. Several factors that affect the survival rate include the condition of the aquatic environment and human activities around it.

“…Salah satu jenis lamun yang keberadaannya melimpah dan memiliki kandungan antioksidan adalah E. acoroides (Permana et al, 2020), namun pemanfaatan lamun belum banyak dilakukan di Indonesia (Mardiyana et al, 2014). Lamun berpotensi besar dikembangkan menjadi pelembap bagi kulit (Arif et al, 2021), sumber neutraceutical yang baik (Amudha et al, 2018), serta efektif menghilangkan bakteri penyebab penyakit pada manusia (Rappe et al, 2019).…”

Kulit merupakan bagian tubuh yang sensitif terhadap perubahan suhu akibat aktivitas di dalam dan di luar ruangan. Salah satu produk kosmetik yang dapat mengatasi kulit kering dan bersisik akibat perubahan suhu adalah moisturizer body lotion berbahan lamun dan gonad bulu babi. Tujuan dari penelitian ini adalah menentukan formulasi yang optimal pada sediaan moisturizer body lotion berdasarkan karakteristik stabilitas fisik, hubungan indeks iritasi dengan hasil uji kesukaan panelis, serta kandungan fitokimia pada sediaan moisturizer body lotion dari ekstrak lamun (Enhalus acoroides) dan gonad bulu babi (Diadema setosum). Penelitian ini terdiri dari pembuatan ekstrak, pembuatan produk tanpa penambahan ekstrak lamun dan gonad bulu babi (kontrol) serta dengan penambahan (2:1, 1:2, dan 3:3), uji stabilitas, uji iritasi, dan uji fitokimia. Hasil penelitian menunjukkan bahwa terdapat perbedaan warna pada empat formulasi body lotion yaitu putih (kontrol), seledri (2:1), sage (1:2) dan zaitun (3:3) dengan bau khas blossom. Kisaran pH pada sediaan yaitu 6,31-8,05 dan rentang daya sebar sebesar 3,2-6,7 cm. Hasil uji indeks iritasi dari 32 panelis terdeteksi sebanyak 3% terindikasi gejala iritasi edema parah (bengkak) dan indeks rasa panas terdeteksi sebanyak 1%. Nilai uji kesukaan panelis tertinggi untuk indikator warna, aroma dan tekstur terdapat pada sediaan tanpa penambahan ekstrak lamun dan gonad bulu babi (kontrol). Sediaan moisturizer body lotion mengandung senyawa alkaloid dan tanin. Fomulasi terbaik yaitu perbandingan ekstrak lamun dan gonad bulu babi 2:1 yang ditandai dengan tingginya uji hedonik (warna), tidak adanya indeks iritasi edema, dan rasa panas.
