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).
