| dc.description.abstract | The mangrove forest is a complex ecosystem consisting of flora and fauna
that live at the same time between the tidal and low tide boundaries. The purpose
of this study was to analyze the effect of spacing on the growth of red mangroves
(R. apiculata) offshore in the mangrove forest area of Pulau Village, using R.
Apiculata seedlings. This research activity was carried out for 3 months from
August to October 2021. This study used a Completely Randomized Design (CRD)
method with 6 repetitions and 5 treatments. The distances used in this study were
P0 = 36 meters, P1 = 37 meters, P2 = 38 meters, P3 = 39 meters and P4 = 40
meters. Based on the results of the analysis of variance (ANOVA) it was found
that the spacing treatment from the beach had a significant effect on the growth of
height and diameter of R. apiculata seedlings, but had no significant effect on the
increase in the number of leaves and leaf area of the seedlings. From this study,
the best spacing was obtained in the P2 treatment with a spacing of 38 m from the
shoreline with the highest average growth values for seedling height and seedling
diameter, namely 37.4 cm/12 weeks and 1.32 mm/12 weeks. As for the leaf area
observation parameter with the highest average value found in the P0 treatment
with a value of 16.79 mm/12 weeks, while the number of leaves parameter
obtained the highest average value in the P1 treatment with a value of 6.25
strands. | en_US |
