Pengaruh Penanaman Sistem Rumpun Berjarak Terhadap Kelulushidupan Dan Pertumbuhan Avicennia Marina Di Selat Lalang Kampung Kayu Ara Permai Kecamatan Sungai Apit Provinsi Riau

Abstract
The distance clump system is a method of planting with close spacing in clumps. The function of the clump is to strengthen mangrove and trap nutrients (mud). This study aims to determine the survival rate of the growth of Avicennia marina mangrove seedlings using the clump system planting method. In addition, this study also aims to determine the optimal number of seed stands in one clump. The research was conducted in June-August 2021. The method used in this study was a completely randomized design trial with the treatment factor being the number of different stands of Avicennia marina mangrove seedlings in one clump. The treatments consisted of 3 treatments, namely the number of Avicennia marina mangrove seedlings 50 stands/clump (T1), 100 stands/clump (T2) and 150 stands/clump (T3). Data analysis used ANOVA test to see the effect of the number of stands in one clump on survival, stem height and number of leaves of Avicennia marina. The observations were made two weeks after planting for 6 weeks. The environmental factors measured were pH, salinity, temperature, current speed, organic matter and sediment fraction. The results showed that the survival rate of mangroves in P1 treatment was 75.8%, P2 87.5% and P3 92.9%. The good survival rate was P3 treatment (150 stands/clump) with a percentage value of 92.9%. The average growth of Avicennia marina mangrove stems for 6 weeks was 0.73cm P1, P2 0.69cm and P3 0.71cm and the increase in the number of leaves was P1 1.20, P2 1.43 and P3 1.40 leaves.
Keywords: Avicennia marina, Survival, Distance Clump System.
