Status Keberkelanjutan Pengelolaan Ekosistem Mangrove di Kepenghuluan Serusa Kabupaten Rokan Hilir Provinsi Riau
Mangrove ecosystems plays important role as habitat of aquatic organisms in the coastal areas. The condition of the mangrove were affected greatly by tidal, weather and anthropogenic activities conducted around that area. In the Serusa Village that is located in the Rokan Hilir Regency, the mangrove area was degraded due to human activities such as mangrove logging and land conversion into oil palm plantations. The damage of the mangrove ecosystem caused ecological, economical and social losses. This research aims to analyze the existing conditions and the sustainability status of the mangrove ecosystems in that area. Information obtained from this research will be used to design a sustainable mangrove ecosystem management strategy.
This research was conducted in December 2023 - January 2024. A survey method was applied and data obtained were classified into primary and secondary data. The primary data were obtained from field observations, measurements and in-depth interviews to get information on mangrove community structure, types of organisms living in the mangrove, water quality, organic matter and substrate types. Other data were collected through questionnaire and interviewing 7 expert and 30 community respondents. The secondary data were taken from related institusions including: Riau Provincial Environment & Forestry Service, Rokan Hilir Regency Fisheries & Marine Service, Rokan Hilir Regency Environmental Service, Community Leaders, Head of Forest Farmer Groups Serusa Berjaya, Peat & Mangrove Restoration Agency, and Fisheries Intructor.
The sustainability status of the mangrove in the Serusa was analyzed using a Rap-SerusaMF, an application which was modified from Rapfish. The analysis steps were as follows: (1) Determining the dimensions and attributes as assessment criteria. (2) Conducting assessment by scoring each attribute. (3) determining the sustainability index value using an Ordination analysis, (4) Performing leverage analysis to obtain sensitive attributes. (5) Performing Monte Carlo analysis to consider the uncertainty aspect of the analysis.
Results of the analysis of the ecological dimension show a sustainable category (77.41%), the economic dimension shows a fairly sustainable category (52.34%), the socio-cultural dimension shows a less sustainable category (48.80%) and the institutional legal dimension shows a less sustainable category (47.68%). Determinant attributes that strongly influence the ecological dimension were as follows: mangrove species diversity, mangrove forest reforestation program, mangrove density, water quality conditions and sediment organic matter content. Economic dimensions include: community income level, government budget to manage mangroves and mangrove land use zoning. Socio-cultural dimensions include: distance between settlements and the area, level of education and potential land use conflicts. Legal and institutional dimensions include: punishment for violators, availability of formal and informal institutions and coordination between institutions/stakeholders.
Based on data obtained, it can be concluded that the mangrove ecosystem area in Serusa Village consisted of two families namely Acanthaceae (Avicennia alba, A. eucalyptifolia and A. lanata) and Rhizophoraceae (Rhizophora apiculata and R. apiculata). The condition of the mangrove ecosystem in Kepenghuluan Serusa is classified as “good” with 1,337.04 trees/ha. Based on ecological, economical, socio-cultural and institutional legal dimensions, results of the Rap-SerusaMF Ordination analysis was 54.70% (fairly sustainable). Sustainable mangrove area management strategies recommended in the Kepenghuluan Serusa were (1) mangrove rehabilitation and water pollution control, (2) empowerment of local communities through the development of alternative livelihoods, (3) increasing the monitoring, supervision and law enforcement activities, and (4) increasing the coordination among stakeholders.
