Abstract. Kristiningrum R, Lahjie AM, Masjaya, Yusuf S, Ruslim Y, Ma’ruf A. 2020. Fauna diversity, production potential and total economic value of mangrove ecosystems in Mentawir Village, East Kalimantan, Indonesia. Biodiversitas 21: 1940-1953. Mangroves play important role in life. The benefits of the mangrove ecosystem consist of ecological and socio-economic values. However, it is a challenge to discern how the mangrove ecosystem provides a comprehensive economic value. This research is aimed to analyze the Total Economic Value (TEV) of mangrove ecosystems in Mentawir Village, North Penajam Paser District, East Kalimantan Province. This aim will be achieved by conducting fauna inventory, analysis of mangrove wood production potential, social-economic interviews, and infrastructure cost analysis as the inputs to calculate four elements (i.e. Direct Use Value, Indirect Use Value, Option Value, and Existence Value) to sum up the TEV. The research used a mixed-method combining both qualitative and quantitative methods. Fauna inventory was conducted using boat survey method and interviews with local fishermen. Data on mangrove wood production was obtained using the systematic random sampling method by establishing two plots with an area of one hectare for each plot to calculate mean annual increment (MAI) and current annual increment (CAI). The economic value of the mangrove ecosystem was calculated using market price values, replacement costs, and the Contingent Valuation Method (CVM). The results of fauna inventory consisted of 3 species of mammals, 1 species of reptile, 16 species of birds, 25 types of fish, 8 species of crustaceans, and 7 species of mollusks. The economic valuation resulted in the contribution of direct use value with 39.56% in the form of wood (94,875,000,000 IDR) and fishery products (103,500,000,000 IDR); indirect use value with 53.47% in the form of breakwater (38,028,881,407 IDR), abrasion resistance (218,549,528,110 IDR), and carbon sequestration (11,580,313,067); option value with 6.92% in the form of biodiversity (34,690,085,038 IDR); and existence value with 0.05% (241,500,000 IDR). All these resulted in the total economic value (TEV) of the mangrove ecosystem in Mentawir Village of 501,465,307,621 IDR. Therefore, this value can be the basis for policymakers in managing natural resources so that the ecosystem is more protected and sustainable, and can continue to provide environmental services for the welfare of the community.

 Substrat mangrove terdiri atas fraksi pasir (sand), lumpur (silt), dan liat (clay). Gastropoda adalah kelompok hewan dari filum moluska yang hidup di jenis substrat dari kasar ke halus. Kelimpahan gastropoda dipengaruhi oleh substrat dasar yang merupakan habitat dari gastropoda, serta kandungan nutrien yang berbeda pada tiap fraksi akan mempengaruhi kelimpahan Gastropoda yang berada di dalamnya. Oleh karena itu, perlu dilakukan penelitian mengenai hubungan substrat dengan kelimpahan Gastropoda, karena Gastropoda salah satu faktor penting untuk menjaga keseimbangan ekologi pesisir khususnya ekositem mangrove. Penelitian  dilakukan di Hutan Mangrove Kulonprogo Yogyakarta bertujuan untuk mengetahui tipe substrat, kelimpahan Gastropoda dan hubungan kedua variabel tersebut. Penelitian  dilakukan pada bulan April sampai dengan  Mei 2017. Metode yang digunakan adalah metode deskriptif yaitu metode penelitian yang memberikan gambaran secara sistematis, faktual, akurat mengenai faktor-faktor dan sifat-sifat dari suatu daerah atau populasi. Metode pengambilan sampel substrat dan Gastropoda menggunakan metode Purposive Sampling Method pada 3 stasiun berbeda yaitu stasiun I pada bagian dekat pemukiman penduduk, stasiun II pada bagian dekat tambak, dan stasiun III pada bagian muara sungai. Hasil penelitian menunjukkan jenis substrat pada tiap stasiun adalah lempung dan lempung berdebu yang didominasi oleh fraksi lumpur (silt) dan pasir (sand). Jenis Gastropoda yang didapatkan berasal dari genus Littoraria, Natica, Faunus, Cerithium, Neritina, Polinices, Conus, Telescopium, dan Nerita. Meningkatnya prosentase fraksi pasir (sand) dan liat (clay) akan diikuti oleh meningkatnya kelimpahan Gastropoda, sedangkan untuk fraksi lumpur (silt) akan sebaliknya yaitu meningkatnya fraksi lumpur akan diikuti oleh menurunnya kelimpahan Gastropoda. Kata kunci: Tipe Substrat, Gastropoda, Mangrove, Kulonprogo  Mangrove substrates formed by sands, silts, and clays. Gastropods is a group of animals of the phylum of mollusks lives on the type of substrate from rough to smooth. Gastropod abundance is affected by substrate which habitat of gastropods and nutrients influencing the distribution of gastropods. Therefore, it needs a deeper research about the correlation of substrate and the amount of gastropods , because gastropods are the importants factor of mangrove ecosystem. The research helds in Kulonprogo Mangrove Forest, Yogyakarta, and the goals are to know the type of substrate, the amount of gastropods, and the correlation among them. This research held on April – Mei 2017. This research use descriptivemethod wich research method that provide a systematic, factual, accurate description of the factors and quality an area or population. The method on sampling sediments and gastropods is purposive sampling in 3 station. Station 1 near the settlement, station 2 near ponds, station 3 on the estuary. The results of this research shows that the sediments on every station are clay and dusty clay, which is dominated by silt,and sand fraction. The gastropods that obtained are Littoraria, Natica, Faunus, Cerithium, Neritina, Polinices, Conus, Telescopium, and Nerita. The percentage increasing on sands and clays fraction would be more gastropods. Otherwise on silts fraction.

The city of Surabaya has been voted as one of the pilot areas of mangrove forest conservation in ASEAN. Most of the mangrove forest area in the city of Surabaya spread across the East Coast (Pamurbaya). The purpose of this study is to estimate the total economic value of mangrove forests in the area as a source of information for planning and evaluation of conservation policy. The results of the valuation involving some valuation techiques, both market and non-market approaches, yield total economic value of about Rp 49.6 billion (US$ 3.8 million) per year, or 105.3 million (US$ 8,101.8) per ha per year. Almost all of these values is the use value, particularly direct use valule both extractive (timber and fisheries) and non extractive (outdoor recreation). Indirect use value which consists of abrasion barrier and carbon sinks contributed relatively small compared to the direct use value. Meanwhile, non-use value is the smallest contributors to the total economic value. This fact proves that the mangrove forest in Pamurbaya has economic benefits outweigh the ecological benefits. Keywords: economic valuation, mangrove, non-market approach, the city of Surabaya
