Abstract: | Padang lamun berperan penting sebagai pendaur ulang zat hara di perairan,
namun memiliki ancaman di habitatnya akibat berbagai faktor sehingga bisa
hilang di suatu wilayah pesisir. Salah satu upaya untuk memulihkan padang lamun
adalah transplantasi. Tujuan penelitian adalah menerapkan metode sprig anchor
dan karung goni untuk transplantasi lamun Thalassia hemprichii serta mengukur
laju sintasan dan pertumbuhan. Kegiatan transplantasi dilakukan pada bulan
Maret-Juni di Pulau Pramuka, Kepulauan Seribu dengan dua metode yang
masing-masing terdiri atas 40 bibit. Hasil persentase survival rate lamun dengan
metode transplantasi sprig anchor lebih rendah (32.5%) dibandingkan metode
karung goni (87.5%). Pertumbuhan panjang daun lamun T. hemprichii
menggunakan metode transplantasi sprig anchor memiliki kisaran panjang 11.29
– 14.10 cm, sedangkan pada metode karung goni memiliki kisaran panjang 11.54
– 13.92 cm. Laju pertumbuhan lamun T.hemprichii menggunakan metode
transplantasi sprig anchor memiliki kisaran nilai 0 - 0.58 cm/minggu, sedangkan
pada metode karung goni memiliki kisaran nilai 0 - 1.14 cm/minggu. Seagrass beds have an important role in maintaining the balance of the sea as a recycler of nutrients in the waters, but have threats to their habitat due to various factors so that they can be lost in a coastal area.. One of the efforts to restore the seagrass beds is by transplantation. The objective of this research was to apply two methods of seagrass transplantation for Thalassia hemprichii, namely sediment-free sprig anchor (sprig anchor) and sediment-filled hessian bags (hessian bags), also measure its survival and growth rate. Transplantation activities were carried out in March-June on Pramuka Island, Seribu Islands using two methods, each consisting of 40 seedlings. The percentage result of seagrass survival rate using sprig anchor transplantation method is lower (32.5%) than the burlap sack method (87.5%). The length growth of the leaves of T.hemprichii seagrass using the sprig anchor transplant method has a length range of 11.29 – 14.10 cm, while the hessian bags method has a length range of 11.54 – 13.92 cm. The growth rate of seagrass T. hemprichii using the sprig anchor transplant method has a value range of 0 - 0.58 cm/week, while the hessian bags method has a value range of 0 - 1.14 cm/week. |
