| Summary: | Wanagama I is an educational forest that was built at critical land. The
success of developing forest create a big improvement with at least 13 stands were
established. Wanagama I at the beginning was an area covered by stone and little
soil but it has 20-80 cm of soil layer now. The improvement will influence the
hydrological cycle in Wanagama I. One of the components is soil infiltration
capacity as a success parameter of developing forest.The purpose of this research
is to measure and compares the infiltration capacity of various stands and an
empty land in Wanagama I and assesses the use of two different methods : the
single ring and double ring infiltration method.
The single ring and double ring infiltration method was applied to measure
the infiltration capacity. The characteristic of vegetation and soil was collected to
compare the characteristics of stand. The assessment of two different methods
were analyzed by Wilcoxon analysis.
The result showed that Wanagama I has 13 types of stand with wide range
of infiltration capacity. The 13 stands consist of Swietenia macrophylla with
0.04cm/hour infiltration capacity, Eucalyptus pellita 0.40 cm/hour, Melaleuca
cajuputi 0.06 cm/hour, Diospyros celebica 0.08 cm/hour, Gmelina arborea 0.8
cm/hour, Eucalyptus alba 4.00cm/hour, Eucalyptus urophylla 0.08 cm/hour,
Acacia mangium Willd. 0.1 cm/hour, Pinus merkusii 0.4 cm/hour, Acacia
crassicarpa 0.2 cm/hour, Tectona grandis 0.15 cm/hour, Acacia auriculiformis
0.1cm/hour and empty area 0.4 cm/hour. The biggest capacity owned by Cassia
siamea 6.0 cm/hr. The Wilcoxon analysis result shows 0.279 of significant
number means there�s no significant different. |
