ECONOMIC VALUATION OF MANGROVE ECOSYSTEMS AND THEIR CONTRIBUTION TO HOUSEHOLD INCOME: CASE STUDIES AT PEMOGAN, TUBAN, AND KUTAWARU VILLAGES

Ekosistem mangrove memiliki fungsi fisik, ekologi, dan ekonomi bagi manusia. Pemanfaatan mangrove yang tidak konservatif dapat menimbulkan kerusakan mangrove dan abrasi. Pemulihan ekosistem mangrove dengan rehabilitasi dan konservasi dapat meningkatkan pendapatan masyarakat. Peningkatan pendapatan masyarakat ini mendorong diperlukannya perhitungan valuasi ekonomi terhadap ekosistem mangrove. Tujuan dari penelitian ini adalah mengetahui total use value dan non use value ekosistem mangrove di Desa Timbulsloko, Kecamatan Sayung, Kabupaten Demak. Metode yang digunakan dalam penelitian ini adalah metode deskriptif untuk menghimpun data monografi terkait ekosistem mangrove dan metode eksploratif untuk penentuan use value dan non use value ekosistem mangrove. Responden penelitian adalah 30 orang terdiri dari 29 masyarakat dan 1 orang perangkat desa yang berkaitan dengan keberadaan ekosistem mangrove secara langsung dan tidak langsung. Penelitian dilakukan pada Bulan September – Desember 2017. Hasil penelitian menunjukan nilai total ekonomi ekosistem mangrove di Desa Timbulsloko adalah Rp 164.897.377,1/ha/tahun atau Rp 12.703.693.939/ tahun dengan luasan ekosistem mangrove 77,04 ha. Nilai tersebut terdiri dari total use value dan non use value dari sektor perikanan dan kelautan yang terkait dengan ekosistem mangrove. Use value sebesar Rp 11.095.403.189/tahun atau Rp 144.021.329/ha/tahun. Use value meliputi nilai guna langsung, nilai guna tidak langsung, dan nilai pilihan. Sedangkan non use value sebesar Rp 1.608.290.750/tahun atau Rp 20.876.048,16/ha/tahun. Non use value meliputi nilai keberadaan dan nilai warisan. Mangrove ecosystem has physical, ecological and economical functions for humans. Non conservative use of mangrove can cause mangrove damage and abrasion. Restoration of mangrove ecosystems with rehabilitation and conservation can increase community income. The increasing of community income can cause the need of economic valuation calculations for the mangrove ecosystem. The purpose of this study was to determine the total of use value and non-use value of the mangrove ecosystem in Timbulsloko Village, Sayung District, Demak Regency. The method used in this study was a descriptive method to collect monograph data related to mangrove ecosystems and an exploratory method for determining use value and non-use value of the mangrove ecosystem. The research respondents were 30 residents consisting of 29 communities and 1 village officer who were directly and indirectly related to the existence of the mangrove ecosystem. This researched was conducted in September – December 2017. The result showed that the total economic value of the mangrove ecosystem in Timbulsloko Village was Rp. 164,897,377.1 / ha / year or Rp. 12,703,693,939 / year in 77.04ha of mangrove ecosystem area range.

Mangrove ecosystems become an important ecosystem for the community of Mandah district, this is because the community uses the mangrove ecosystem as a producer of mangrove wood, as well as a place to catch fish, shrimp, and crabs. Therefore, it is important to maintain the sustainability of mangrove ecosystems in multiple ways; one option is by providing an economic report regarding the mangrove ecosystem. The purpose of this study is to estimate the economic value of mangrove ecosystems. This research was conducted in Mandah District using the survey method. Data analysis using economic valuation by calculating the total economic value of mangrove ecosystem services, comprising: supporting services, provisioning services, regulating services, and cultural services. The results showed that the total economic value of mangrove ecosystem services which has an area of 31,007 Ha amounting to IDR 6,100,130,675,685/year or IDR 196,733,985/Ha/year consisting of the value of supporting services amounting to IDR 2,843,521,034,280/year, the value of provisioning services IDR 120,274,922,887/year, the cost of regulatory services is IDR 3,132,894,718,518/year, and the value of cultural services is IDR 3,440,000,000/year. The high economic value of regulating and supporting services indicates that the mangrove ecosystem has a high value of environmental services, so it needs to be preserved and the sustainability of the mangrove ecosystem to remain of high economic value.

Introduction/Main Objectives: This study estimates how much economic value will be lost from contact activities within the coastal areas in the research location. Background Problems: The area of Semarang City has flood and tidal problems, the damage to the mangrove forests in Semarang City began with the boom in shrimp farming between 1980 and 1990. Hopefully, this valuation can provide an overview of the current health of the ecosystem and become the basis for a mangrove management strategy in the future. Novelty: The novelty of this study is that it uses a sharper satellite (Image Pleades Resolution 0.5 m) to calculate the mangrove area in the research location. Research Methods: This research uses a total economic valuation, an estimation of the mangrove’s carbon stock and heavy metals, the replacement cost to prevent tidal flooding, and the willingness to pay. Findings/Results: We find that the existing economic value in the study area is very large and should be preserved for conservation. Conclusion: The environment cannot produce something instantly, but it needs to be preserved as a balance to nature.

Mangrove Ecosystems

Muara Angke merupakan satu – satunya kawasan yang masih memiliki ekosistem mangrove di daerah pesisir Jakarta. Luas Muara Angke kurang lebih 964,98 ha dibagi menjadi tiga zona. Dua diantaranya berkontribusi pada sektor Perikanan dan Ekowisata, yaitu Pangkalan Pendaratan Ikan (PPI) dan Taman Wisata Alam Angke Kapuk (TWAAK). Kurangnya pemahaman umum tentang manfaat ekonomi ekosistem mangrove menyebabkan masyarakat mengeksploitasi secara berlebihan sehingga terjadi perubahan penggunaan lahan. Tujuan penelitian ini untuk mengetahui nilai ekonomi yang dihasilkan ekosistem mangrove berdasarkan dua aspek yaitu Perikanan Tangkap dan Ekowisata. Data Perikanan Tangkap menggunakan data sekunder dari Pengelola PPI Muara Angke tahun 2016 – 2017. Data sosial ekonomi diperoleh menggunakan wawancara dengan bantuan kuesioner. Data biaya perjalanan rata – rata diperoleh dengan wawancara pengunjung TWAAK. Analisis Valuasi Ekonomi Perikanan Tangkap menggunakan Market Price Method. Analisis Valuasi Ekonomi Ekowisata Mangrove menggunakan Travel Cost Method. Metode penentuan 100 responden nelayan tangkap menggunakan Random Sampling sedangkan penentuan 100 responden pengunjung TWAAK menggunakan Accidental Sampling. Hasil penelitian didapatkan nilai ekonomi pada aspek perikanan tahun 2016 Rp. 13.148.945.100, tahun 2017 Rp.21.087.388.300 dan tahun 2018 Rp. 370.313.869.500. Hasil penelitian didapatkan nilai ekonomi ekowisata tahun 2018 Rp.40.28.400.000 Muara Angke is the only area that still has mangrove ecosystems in the coastal areas of Jakarta. Muara Angke area is approximately 964.98 ha divided into three zones. Two of them contribute to the Fisheries and Ecotourism sector, namely Fish Landing Base (PPI) and Angke Kapuk Nature Park (TWAAK). Lack of general understanding of the economic benefits of mangrove ecosystems causes people to over-exploit so that land use changes occur. The purpose of this study was to determine the economic value generated by mangrove ecosystems based on two aspects, namely Capture Fisheries and Ecotourism. Capture Fisheries Data uses secondary data from Muara Angke PPI Manager in 2016 - 2017. Socio-economic data were obtained using interview with Muara Angke fishermen with questionnaire assistance. Average travel cost data is obtained by interviewing TWAAK visitors. Capture Fisheries Economic Valuation Analysis using Market Price Method. Economic Valuation Analysis of Ecotourism Mangroves use the Travel Cost Method. The method of determining 100 respondents of capture fishermen uses Random Sampling while the determination of 100 respondents of TWAAK visitors uses Accidental Sampling. The results of the study obtained economic value in aspects of fisheries in 2016 Rp. 13,148,945,100, in 2017 Rp.21,087,388,300 and in 2018 Rp. 370,313,869,500. The results of the study obtained the economic value of ecotourism in 2018 Rp. 40.28.400.000
