Interpretation of Sustainability Factor in Wonorejo Mangrove Ecotourism, Surabaya, Indonesia

Mangrove Ecotourism Wonorejo Forest (EHMW) is designed by the Surabaya City’s government to have some aspects of nature and education to conservation that may help to save the environment and economy, especially through the tourism. some ecologists revealed that the development of tourism in EHMW runs not balanced and not oriented to the principle of sustainability. This study aims to determine the level of sustainability of EHMW management in Surabaya based on analysis of three sustainability criteria. The study was conducted from September to October 2017. We conducted two methods of data collection: interviews and questionnaires. Assessment is grouped into four levels of sustainability status (%): 0.00-25.00 (unsustainable); 25.01-50.00 (less sustainability); 50.01-75.00 (sufficient sustainability); and 75.01-100,00 (continuous). EHMW management goes into sustainable criteria (77.18%). The value of the sustainability of all criteria is still below 50.1%, or less sustainable. Each criteria’s value was ecology criteria of 29.38%, on the economic criteria of 28.17% and on the social criteria of 19.63%.

INTRODUCTION 1  Indonesia has the largest mangrove area in the world, approximately 4,252,000 hectares, and most of this area are outside of Java Island [1].Spalding [2] inform that 40% of Indonesia's mangrove forests have been converted to agriculture, fish ponds, and coal industries in South Sulawesi, South Kalimantan and Northern Java [3].Mangrove is an important component of the coastal ecosystem balance [4].Ecologically, mangrove serves as a coastal protection from tsunami [5], erosion barriers, sediment catchers [6], carbon sequestration [7], recycling the nutrients [8,9], maintaining fisheries process [10; 11], preserving biodiversity [12], and preserving coastal ecosystems [13].In addition, mangroves also help reduce the risk of global warming [14,15,16].
Mangrove Ecotourism Wonorejo Forest (EHMW) is designed by the Surabaya City's government to have some aspects of nature and education to conservation that may help to save the environmental and economical values [17,18], especially through the tourism [19][20][21][22][23].
However, some ecologists revealed that the development of tourism in EHMW runs not balanced and not oriented to the principle of sustainability [24].Tourism development that generally runs rapidly and prioritizes economic interests, will reduce the value of its benefits to the overall context of sustainable tourism, such as justice, environment, economy and, in particular, its effects on the economic dimension, environmental resource management, and sociocultural development [25,26].Ecotourism cannot be separated by the conservation efforts, so ecotourism is called the effort of responsibility towards nature [27,28].
EHMW management requires the adoption of sustainable management concepts based on a sustainable development triangle framework.This framework illustrates that sustainable development is oriented towards three mutually supportive and related sustainability dimensions: the ecological, economic and social dimension [29,30].This study aims to determine the level of sustainability of EHMW management in Surabaya based on analysis of three sustainability criteria.

MATERIALS AND METHOD Study sites
The research was conducted at EHMW, Wonorejo Village, Rungkut subdistrict, Surabaya.This area covers 648,453 ha and located at ±2 km Sustainability Factor in Wonorejo Mangrove Ecotourism (Parmawati, et al.) [18] J. Ind. Tour.Dev.Std., Vol.6, No.1, January 2018 east from Surabaya city.Since 2007, the area was developed as a tourist and conservation area, both the ecosystem and the physical coast of abrasion.EHMW is established on municipal government land and its development is dependent on Surabaya Regional Budget and Expenditure (Anggaran dan Pendapatan Belanja Daerah).This area has good both of the main and supporting facilities, such as parking area, management office, nursery, track, canteen, mosque, public toilets, playground, pier, counters, jogging track, and rest area.Some private-owned boats can also be used to roam the mangrove area.

Data collection
The study was conducted from September to October 2017.We conducted two methods of data collection: interviews and questionnaires.Determination of the respondents was done randomly, sampling with a balanced amount based on the background, so it is considered that every respondent has the same opportunity.The object on this method is the community, visitors and managers (n=30).The topic of the questions consists of the perception and knowledge of the respondents about the sustainability of ecotourism on ecological, economic, and social sustainability.

Analysis
The data were processed and analyzed based on the total score of questions of the questionnaire using Likert scale (Table 1).The results were analyzed using Factor Analysis.Furthermore, to assess the sustainability of EHMW management, assessment is used based on modifications from Suwarno [31].Assessment is grouped into four levels of sustainability status (%): 0.00-25.00(unsustainable); 25.01-50.00(less sustainability); 50.01-75.00(sufficient sustainability); and 75.01-100.00(continuous).We built 6 indicators of sustainability that will be explored, including 1. Ecology (mangrove area expansion, mangrove's benefits information, and community involvement on protecting the environment), 2. Economy (small community's business), and 3. Social (community involvement on management and maintaining sustainability).

RESULT AND DISCUSSION
The EHMW sustainability indicators are shown in Table 2. Based on the analysis of these indicators, it is known that EHMW management goes into sustainable criteria (77.18%).However, through more specific observations the value on the sustainability at all criteria is still below 50.1%, or less sustainable.Each criteria's value was environmental criteria of 29.38%, on the economic criteria of 28.17% and on the social criteria of 19.63% (Fig. 1).
Environmental criteria have the highest value among the two other criteria measured.The expansion of mangrove forests contributes the greatest value in sustainability to environmental criteria (14.83%).Expansion is due to continuous planting activities by visitors and government.It is also revealed by the community that the conservation of mangrove forest in EHMW is considered getting better due to the expansion.In addition, information is also considered quite influential.Educative information regarding on the benefits of mangroves is present in the EHMW management section.The environmental component is the basic concept of building an ecotourism and is the most important part to be considered and protected on its management [32].Attention to the environment, being one of the distinguishing features between ecotourism and mass tourism [33,30].A well-grown ecotourism activity can be illustrated by the substantial contribution of these activities to local community life and environmental conservation [34], including higher reforestation activities as demonstrated by EHMW's management facts.
In addition to the expansion of mangrove areas, there are educational activities that become indicators of environmental criteria [35].This activity is a sharing of information about the types of flora, fauna, and benefits of mangrove forests for humans.However, this activity was not considered to work properly.Most tourists and managers still consider EHMW has no different from mass tourism.In fact, education is one of the distinguishing features between ecotourism and mass tourism.There is a responsibility of the managers and tourists to understand the benefits of eco-tourism objects for the environment and people, so hopefully the principle of sustainability can be met each other [27].Education on ecotourism is also a kind of learning and experience process, thus becoming something unique and even worth selling [36].
Sustainability Factor in Wonorejo Mangrove Ecotourism (Parmawati, et al.) [19] J. Ind. Tour.Dev.Std., Vol.6, No.1, January 2018 Community involvement on waste management is still very low.Their participation can be seen from a small portion of society that less coordinated to collect and manage waste in the EHMW.Most of the waste management is done by the manager [37].Nevertheless, the community should be included at the part of waste management so they can share their ideas and participate on the waste management activities, starting from the planning, implementation and evaluation of the program [38].The participation of the community on managing the ecotourism area is not only aimed at benefiting and experiencing it, but also maintaining the tourist attraction in harmony with the objectives of environmental conservation, building awareness and respect for the environment and culture, and awakening the sensitivity of managers, communities and visitors to social, political, economic, ecosystem services and its environmental impacts [39,40].
The economic criteria is stated to be less continuous in this study (28.17%).The indicators that affect the economic criteria are small business management policies around EHMW.Although it was stated less continuous, but the existence of EHMW Surabaya revealed by the respondents that have a great economic value for the community.However, the level of income is still feasible to be optimized again.The boundaries of the small business community space have not been agreed and socialized, so some parties still doubt the existence of these small business forms.The regulation of the business utilization space needs attention so that the EHMW area can become a source of income and improve the welfare and quality of life of the surrounding community [39,41,42,43].
Social criteria declared unsustainable (19.63%).The results reveal that the public has no desire to participate in managing EHMW in an organizational structure.Communities tend to be limitedly involved in planting projects undertaken or advised by the government.Motivation of this activity is the impact of the abrasion that once reached the home of the citizens.The emergence of ecotourism should be the solution of the effects of environmental damage, as well as improving the welfare of society [34].People's motivation in mangrove ecosystem management, either aimed at achieving improved welfare or with conservation motivation, should emerge independently to support the development and sustainability of an ecotourism [30,44].

CONCLUSION
Mangrove Ecotourism Mangrove Wonorejo Surabaya is stated to be less sustainable on environmental and economic criteria (29.38% and 28.17%) and also unsustainable on social criteria (19.63%).The expansion of mangrove areas strongly supports environmental and economics criteria [45,46].The small business management policy has not optimally supported the economic criteria.The management that has not been done by the community, has impact on the small community initiatives in social criteria [47].
