Based on table 3, it can be concluded that mangrove
of Tuada Beach consisted of 9 different species
which are Rhizophora mucronata L, Bruguiera
gymnorrhiza, Ceriops tagal (perr), Avicennia
marina, Rhizophora apiculata BI, Avicennia
officinalis, Xylocarpus granatum, Xylocarpus
moluccensis and Nypa fruticans. Mangrove in each
station could be different, RhizophorRga mucranata
L, Bruguiera gymnorrhiza, Ceriops tagal (perr),
Xylozarpus granatum and Xylozarpus moluccensi
and Nypa fruticans (1
st
station). Rhizophora
mucronata L, Bruguiera gymnorrhiza, Avicennia
marina, Rhizophora apiculata BI, Xylocarpus
moluccensis, and Nypa fruticans (2
nd
station),
Rhizophora mucronata L, Rhizophora apiculata BI
and Xylocarpus granatum (3
rd
station). Rhizophora
mucronata, Avicennia officinalis and Xylocarpus
moluccensis could be found in 4
th
station, while
Rhizophora mucronata L, and Avicennia officinalis
for the 5
th
station. In average there are 4,2 ~4
different species within the area so that concluded as
moderately suitable (S2) for ecotourism.
3.2 Density and Mangrove Thickness
The distribution of mangrove density in the study
area has a very rare, rare, medium and very dense in
density. Its density is considered not suitable (S3).
Mangrove thickness at I-V station has an average
mangrove thickness 550-600 m. The thickness at the
1
st
station to station 5 can be categorized moderately
suitable (S2) because it is in the value of more than
500 m.
3.3 Slope
The slope of the beach in Tuada village is
categorized as flat to almost flat with a value of ˂
3% so that was highly suitable for ecotourism (S1).
Flat slope and sloping is very suitable for bathing
and swimming activities (Purbani, 1999). A slope
can affect the safety of visitors when bathing and
swimming on the beach. Slope could also effect on
abrasion and a land subsidence, which makes the
soil unstable and change its location, thus affects the
saplings of mangroves that grow and expand along
the coast
3.4 Tidal Range
Based on tidal data from the results of the previous
research and tidal data from Dishidros AL (2009), it
is known that in Jailolo has the same type as other
area in the Halmahera island group, which has two
episodes of equal high water and two episodes of
low water each day (Semi-Diurnal Tide Type).
Data showed that tidal ranges generally range
from 3 to 1,7 meters that could cause more shallow
parts of the water to appear on the surface. The tidal
range concluded moderately suitable (S2) because of
its safety reason and its effects on the vertical
distribution of mangroves.
3.5 Freshwater Supply
The existing water resources in an area greatly
influences the economic activities of the population
in the region. The existence of clean water is very
influential in the development of tourism objects and
the surrounding area. In coastal tourism areas, the
availability of fresh water is the main object besides
sea water. Freshwater sources come from
underground springs and rivers that are adjacent to
tourist sites. The result showed that water resources
in Tuada beach for tourism activities came from
Todowongi River and resident wells within 0.1-0.67
Km perimeter. Based on the criteria in the land
suitability matrix, the availability of fresh water is
categorized as highly suitable (S1) because the
freshwater resource located was only < 0.5 km from
the area. With the presence of fresh water sources
that are close to the beach, this can support the
activities of visitors or tourists. The source of fresh
water is absolutely necessary, especially for the
survival of the population and supporting the
development of the potential for tourism in the area
of small islands (Dahuri, 2003). And when
conducting tourism activities, the availability of
clean water is very necessary to support
management facilities and tourism services
(Handayani, 2010).
