Abstract
Lamun diketahui sebagai salah satu sumber daya laut yang penting karena menyediakan jasa ekosistem laut secara ekologis dan ekonomis. Kondisi lamun di lokasi penelitian telah mengalami penurunan sepanjang tahun 2019; namun belum pernah dilakukan upaya restorasi lamun di lokasi tersebut. Penelitian ini bertujuan untuk mengetahui dan membandingkan nilai kesintasan dan laju pertumbuhan lamun yang ditransplantasi dengan empat metode yang berbeda sebagai upaya restorasi padang lamun. Metode transplantasi lamun yang digunakan pada penelitian ini adalah sprig anchor, bmaboo anchor, pot gerabah dan karung goni. Nilai rata-rata laju pertumbuhan lamun tertinggi didapatkan dari metode sprig anchor sebesar 0,4±0,23 cm minggu-1, sedangkan bamboo anchor, pot gerabah, dan karung goni adalah sebesar 0,1±0,16; 0,2±0,22; dan 0,1±0,06 cm minggu-1. Selanjutnya untuk nilai tingkat kesintasan tertinggi juga didapatkan dari metode sprig anchor sebesar 100%, sedangkan bamboo anchor, pot gerabah, dan karung goni mendapatkan nilai sebesar 80%, 80%, dan 50%. Berdasarkan uji One-Way Anova dan Tukey HSD test, data secara statistik menunjukkan adanya perbedaan yang signifikan. Metode sprig anchor memiliki perbedaan laju pertumbuhan panjang daun lamun yang signifikan dengan metode bamboo anchor dan karung goni, tetapi tidak dengan metode pot gerabah dan metode terbaik adalah sprig anchor.

Seagrass is known as one of the important marine resources because it provides marine ecosystem services both ecologically and economically. The condition of seagrass in the reasearch location has decreased throughout 2019; however, no seagrass restoration efforts have been carried out at that location. This study aims to determine and compare the survival value and growth rate of seagrass transplanted with four different methods as an effort to restore seagrass beds. The seagrass transplantation methods used in this study were sprig anchor, bamboo anchor, earthenware pot and gunny sack. THe average value of the highest seagrass growth rate was obtained from the sprig anchor method of 0.4±0.23 cm week-1, while bamboo anchor, earthenware pots, and gunny sacks were 0.1±0.16; 0.2±0.22; and 0.1±0.06 cm week-1. Furthermore, the highest survival rate was also obtained from the sprig anchor method of 100%, while bamboo anchor, earthenware pots, and gunny sacks received values of 80%, 80%, and 50%. Based on the One-Way Anova test and Tukey HSD test, the data statistically shows a significant difference. The sprig anchor method has a significant difference in the growth rate of seagrass leaf length with the bamboo anchor and gunny sack methods, but not with the earthenware pot method and the best method is sprig anchor.
