The approach taken in determining the economic value of mangrove products and services is financial analysis and economic analysis. In financial analysis, a direct approach is used, namely by using market values for marketed commodities and determining the value of substitutes for goods and services that are not marketed. While in the economic analysis, the shadow price or accounting price, namely the value adjusted in such a way as to describe the true value of mangrove goods and services.

Option Value, Existence Value, and Bequest Value of Mangrove in Jerowaru District, Lombok Timur Regency, Nusa Tenggara Barat

“…Hal ini yang yang menyebabkan posisi tawar mangrove terhadap pengubahan status untuk penggunaan lain masih sangat lemah. Padahal berbagai produk non kayu dan jasa lingkungan yang diberikan mangrove sangat beragam dan banyak (Johari et al, 2021;Johari et al, 2022), dan keseluruhan nilai produk dan jasa mangrove nilainya dapat ditentukan langsung dengan menggunakan harga pasar aktual (Motoku et al, 2014;Fadhila et al, 2015;Samosir et al, 2017).…”

“…Beberapa produk HHBK dari mangrove diantaranya berupa bahan makanan dan obat antiseptik dan diabetes, bahan pengawet dan pewarna jala, bahan kosmetik, hasil budidaya ikan, garam, satwa liar, pakan ternak, dan berbagai produk lainnya (Johari, et al, 2009;Wardhani, 2011;Puspitasari, et al, 2012;Hijbeek et al, 2013;Barus & Kuswanda, 2015;Widiastuti et al, 2016;Johari et al, 2021),. Berbagai produk jasa lingkungan mangrove juga sangat banyak seperti konservasi air tawar, mencegah intrusi air laut, mencegah banjir, mencegah abrasi pantai dan mencegah pencemaran, jasa penyimpan karbon, regulasi iklim, melindungi lahan dan tempat tinggal dari topan dan badai, serta menyediakan habitat dan niche ekologis bagi berbagai spesies organisme darat dan laut, menyediakan tempat berlindung (refuge), tempat berkembang biak, dan areal pemijahan (nursery ground) bagi berbagai spesies hewan laut (Tandjung, 2001;Olafson et al, 2002;Jesus, 2012;Santos et al, 2014;Hidayatullah dan Pujiono, 2014;Harahab et al, 2018;Purwanti et al, 2018;Harahab et al, 2021;Johari et al, 2022).…”

“…Di Kecamatan Jerowaru, Kabupaten Lombok Timur, terdapat lahan mangrove, yang selain dimanfaatkan untuk tujuan pendidikan, penelitian, rekreasi, dan wisata alternatif (wisata memancing), juga telah berkembang menjadi pusat area pengembangan perikanan budidaya seperti bandeng, udang, dan kepiting (Sukuryadi dan Ali, 2019;Johari et al, 2021). Mangrove di daerah ini telah dimanfaatkan dan dibuka sebagai areal usaha tambak dan sawah garam yang dianggap sangat ekonomis oleh masyarakat.…”

Analysis of Regional Potential in Merauke Regency Based on Superior Livestock Population Using a Hybrid Algorithm

“…Regional potential clustering in the livestock sector combines the Location Quotient (LQ) and hierarchical methods. The LQ method is a technique for analyzing the performance of a leading base sector [13] by measuring relative concentration [14] based on a comparative approach to the potential of an area [15]. Identifying leading sectors using LQ is the first step to determining policy-making in developing economic sectors [16].…”
