Edco-tourism; A Coastal Management Program to Improve Social Economics

Coastal erosion is a natural process even in pristine environments. Mangrove is tropical coastal vegetation that may prevent and controls the soil erosion. As the longest coastline country in the world, Indonesia has great ecological potential of mangrove. Sadly, according to Food and Agriculture Organization (FAO) since 2007 Indonesia has lost 40% of mangrove forest because of deforestation for the last three decades. Langkat regency placed as the most destructive mangrove forests in North Sumatera about 25% of total area hectares due to severe damage. Green Belt Lubuk Kertang is a Corporate Social Responsibility (CSR) program held by PT PERTAMINA EP Asset 1 Pangkalan Susu Field (PEP) aims to overcome deforestation problem by implementing the concept of edco-tourism mangrove. Edco-tourism is a concept that combines educational and environmental as the basis of local tourism management. By implementing this concept PEP may create multiplier effect not only by saving environmental issues but also socio - economical for local communities. This study shows the impacts of the program for some aspects. By using Shannon – Wienner indicator shows the biodiversity index has increased since the program began three years ago. Not only biodiversity number but also group’s income of local community increase obtained from the retributions. Furthermore, this program is social investment for PEP to engage company – community relations during operational by gaining license to operate. PEP attempt to implement integrated coastal zone management to balance environmental, technical, socio – economic and recreational objectives, into an eco – coastal sustainable system.


Introduction
As the biggest archipelago's country in the world, Indonesia has more than 90.000 km coastlines with enormous undiscovered of coastal potential. About 14 millions of Indonesia's people or at least 7,5% from total rely their livelihoods in coastal areas [1]. According  ecosystem. One of the ecosystems is mangrove that performs as production, protection and preservation area. About 3 million hectares of mangrove forest grow along Indonesia's coastline. This is 23 percent of all mangrove ecosystems in the world [2]. Ecologically, Mangroves perform several functions such as inundation control, protection from erosion, storm, floods, and wave damage, recreation/ tourism, and generate tangible goods (such as fishes, shellfishes and other forest products). They possess distinct ecological attributes at multiple levels of organization such as site or stand, ecosystem and landscape levels [3]. Mangroves create double impact for the environment, as below the water as breeding and nursing grounds for fish and marine species, as above the water the mangrove trees and canopy serves as a habitat for birds, insects, mammals and reptiles also create economic value by community surround.
Unfortunately, over the past three decades, according to FAO (Food and Agriculture Organization) Indonesia has lost 40 percents of its mangroves. caused by the deforestation, conversion of mangroves area into ponds, settlements, industries and plantations. This means Indonesia has the fastest rate of mangrove destruction in the world [4]. Mangrove deforestations in Indonesia result in a loss of 190 million metric tonnes of CO 2 annually. This accounts for 20 percents of land -use emissions in Indonesia [5] where emissions are estimated to be 700 million metric tonnes of CO2-eq [6] This problem also happens in Lubuk Kertang, Langkat Regency, North Sumatera. In Early 2000s, there are about 80 hectares of mangroves converted into palm oil which made the fishermen loss their livelihoods. About only 25 percents of mangrove forest in Langkat categorized in good condition and the other 75% are damaged and rehabilitation phase. [7] It made Langkat as the most destructive mangroves forest in North Sumatera. As a company which has main working area in Langkat, PT PERTAMINA EP Asset 1 Pangkalan Susu Field (PERTAMINA EP) consequently designed some strategic programs to answer the problems of the society by utilizing some local potentials people barely realized. Green Belt Lubuk Kertang is one of Corporate Social Responsibility program held by PERTAMINA EP which aim to overcome deforestation issues by implementing Edco-tourism Mangrove concept. This concept is not only to promote mangroves tourism; but also to make positive and direct contribution between visitors and the local mangrove guardian community (named 'MEKAR') The combination of triple bottom of CSR (people -planet -profit) mixed into a strategic coastal management program. PERTAMINA EP realizes that being a part of the community may become social investment for the company in the future. PERTAMINA EP sees the problem of land converting will harm the community, coastal ecosystem, natural environment and also indirectly may become as obstacles for the operation of PERTAMINA EP. By implementing this program, PERTAMINA EP creates multiplier effects which improve community in economical and environment benefits. Intangible benefits of mangrove ecosystems include social and cultural functions. Mangrove forests support religious and spiritual values, as well as recreational and aesthetic values for edco-toursim [

Coastal Management Program: Edco-tourism Green Belt Lubuk Kertang
Coastal management is a coordinated strategy to undertake coastal problem and emerging issues such land erosion, public welfare, nature resources and also socio -cultural to minimize the negative impacts and assist coastal society to preserve the environment and create sustainable living based on coastal zone. On the other hand, CSR has been defined in many different ways. At bottom, it refers to companies integrating "social and environmental concerns in their business operations and in their interaction with their stakeholders on a voluntary basis (…) not only fulfilling legal expectations but also going beyond compliance [9]. Green Belt Lubuk Kertang is PERTAMINA EP's social strategy addressing deforestation issues. PERTAMINA EP elaborates the concept of coastal management with CSR itself. Developing the coastal management system in this program by cooperate not only with the community but also government agencies. (see Fig 2.1)

Figure 1. Correlation between Coastal Management and Triple Bottom Line of CSR
There are similarities between the basic concept of CSR and coastal management following elements (Fig 1.1). Through CSR program, PERTAMINA EP takes the initiatives to implement community development strategy based on local wisdom and its potential to achieve the well-being of local communities. Basically, there are three main points that PERTAMINA EP concerns: (i) nature conservation, (ii) ecological education and (iii) economic improvement. Corporate social responsibility (CSR) program can become a source of tremendous social progress, as the business applies its considerable resources, expertise and insights to activities that benefit society [10].

What is Edco-tourism?
The Edco-tourism (education in eco tourism) concept basically based on potential tourism resources. According to The International Ecotourism Society (TIES:2000), "Ecotourism is not only a tourist, but also a responsible natural tourism trip by conserving the environment and improving the welfare of local communities." PERTAMINA EP acquaint the interactive learning conservation for visitors in participating planting mangrove seeds and cultivation of natural ponds. Not only educate but also preserve mangrove vegetation the multiplier effects from the implementation of this program.

Methodology
Social mapping defined as society description systemic processes with conduct data collection and society's information including profiling and social problem in the specific area. According to Netting, Kettner and McMurtry (1993) social mapping can also defined as social profiling. Social mapping is one of many approaches in community development as Twelvetrees [11] said that social mapping is the process of assisting ordinary people to improve their own communities by undertaking collective actions [12]. We're using social mapping research as our based document before creating strategic plan.

Figure 2. Social Mapping Formed
As the result of social mapping and needs assessment PERTAMINA EP will get the recommendation program which we use as groundwork of our CSR program in our main working area.

Method of Effects Measurements
The implementation of Edco-tourism program creates multiplier effects that involve three main aspects.

Environment Effects
Some theories and approaches are used to measure environmental effects. We divided environment category into three main aspects; mangrove, local fauna and the whole conservation area. This research also used as our biodiversity report that describe how PERTAMINA EP practice to protecting environment issues during operational.

Economy Effects
Using quantitative approach by collecting visitors data each month to see total visitors and the revenue that MEKAR get from managing the program. The visitors and revenue graphic used to monitor and evaluate the program to develop the next development strategy.

Social Effects
Public Satisfaction Index (IKM) is data and information derived from costumer satisfaction, in this case community, using two research approaches. Community survey for the quantitative measurements and in-depth interview for the qualitative. This method considering community opinion as database to compare the expectations and needs about the existing CSR program. To measure these aspects, we used different method and indicators as classified in Table 1

Results
At first, Green Belt Lubuk Kertang program is expected to help restore critical land due to deforestation. Programs that initially to save the environment only now develop and creating multiplier effects for the economic and social conditions of the community. This may give the community chance to improve their socio economic by preserving the nature and their coastal local potential for living. PERTAMINA EP also trying to improve the relationship between stakeholders by creating social stability and gain license to operate from the community surround.  has low diversity caused of unstable ecosystem, high ecology pressure, with low productivity. It makes sense, because to restore heavily damaged ecosystem requires a long period of time.     There is an increasing number for mangrove biodiversity in conservation area in Table 6. Though is still in small number but the environment keep improving and evolving. In 2016, we observed that the mangrove biodiversity has increased from 2013 to 2016. In Paluh Tabuhan Timur, biodiversity index increased from 3.173 to 3.95. It also happens in Lubuk Kertang, it increased from 3.173 to 3.98 in 2016. Another impatcs by implementing this program is reduction of carbon (CO 2 ) emission from mangroves zone with total 16, 119 ton / Ha eq.

Economic Effects
Since the implementation of development Edco-tourism program in the beginning of 2017 to April not less than 1000 visitors came to the site. From the retribution, at least IDR 15,000,000/month become the earning of MEKAR's group. This condition also contributes to increase the income of every member from IDR 300,000 to IDR 1,000,000/month. The graphics below are the recordable data from Edco-tourism management. (see Fig 4.1.2 and Fig 4.1.3

Social Effects
Not only services but also program evaluation are needed to create a sustainable development of coastal management. Using Public Satisfaction Index (IKM) PERTAMINA EP try to elaborate with public expectation about the company.
