KEBERHASILAN TUMBUH REHABILITASI MANGROVE DI MUARA SUNGAI KORO PUNA DESA BEGA KECAMATAN POSO PESISIR KABUPATEN POSO

The mangrove ecosystem has physical functions as a wave absorber, storm wind breaker, abrasion protector, mud
retainer and sediment catcher. Apart from that, the mangrove ecosystem also has an ecological function as a nursery
area, spawning area, and search for food for the marine biota that live in it. This research was carried out in Bega
Village, Poso Pesisir District, Poso Regency from November 2023 to December 2023. Starting from conducting field
observations and ending with research. This research uses the plot method, with the placement of observation plots
using Purposive Sampling which is made perpendicular to the coastline to the side. Purposive sampling technique is a
technique for determining samples with certain considerations. The plot size used is 25x40 meters which is placed
diagonally in the rehabilitation area. The total area for mangrove rehabilitation activities in Bega Village is a planting
area of 10 Ha. For this research activity, 10% of the total area taken was 10,000 m2, with a total of 10 plots used. The
results of the research show that the percentage of mangrove plants in Mangrove Rehabilitation activities is mostly
dominated by the Rhizopora apiculata type with a percentage of (73.33%) and the least growing percentage is the
Rhizopora mucronata type with a percentage of (3.00%). Meanwhile, for yield, the highest average plant height was
71.49 cm, namely for the Rhizopora apiculata type, then the lowest average was 27.28 cm for the Rhizopora
mucronata type.
