Valuasi Ekonomi Sumberdaya Hutan Mangrove Di Desa Palaes Kecamatan Likupang Barat Kabupaten Minahasa Utara

Abstract

The purpose of this study to determine the economics value of mangrove forest ecosystems, as well asits contribution to society in the region of mangrove research sites in the Palaes Village, District of WestLikupang, North Minahasa regency. In this research, using primary and secondary data. The variablesmeasured were the direct benefit of the value generated from direct utilization of mangrove forests such asthe potential for wood (timber and firewood), palm leaves craftsmen , catching fish, shrimp and crab(Rp/year). The value of benefits Indirect value resulting from the utilization of mangrove forest indirectlynamed as breaking waves (break water) (Rp/year). Value of benefit options, namely the economic valuederived from potential direct or indirect utilization of a resource / ecosystem in the future the value ofBiodiversity (Rp/year).Based on INP calculation to determine the existence of a species in a community under study, obtainedPalaes Village mangrove forest dominated by Rhizophora at 109,499. INP data from other speciesin a row on the kind of Brugiera of 58,088, amounting to 57,492 Ceriops species, Xilocarpus of 41,491,20,860 species of Sonneratia and Avicennia species amounted to 12,860.Based on the calculations found that the benefits obtained if mangrove forests are maintained atRp10,888,218,123,/year, calculated from the sum of the direct benefits other than timber potential, indirectbenefits and benefits options. Meanwhile, if the potential for exploitation of timber obtained a profit ofRp273,617,273/year. It can be concluded that if the mangrove forest is maintained, then the benefits will39.8 times greater than exploiting the natural resources of mangrove forests Palaes Village.By considering the total economic value derived from the mangrove forest ecosystem in Palaes Village,it has the benefits of mangrove forest and an important functions as economic resources and ecologicalresources for the life of the people who are around him. Therefore, the presence of (physical condition)of mangrove forest ecosystems must be maintained as an asset development, be it by local communitiesand other parties such as government, private sector, researchers and LSM, so that development activitiescan work well and the availability of mangrove forest resources remain secure.

Economic Valuation of Mangrove Forest in the East Coast of the City of Surabaya, East Java Province, Indonesia

“…This value is almost six times higher than the estimation conducted by BAPPEKO (2012) in the same location in 2011, which is around Rp 19 million per ha per year. In addition, the result of this study is also relatively higher compared to similar studies located in Indonesia, such as Ruitenbeek (1992) in Irian Jaya (US$ 212 per ha per year); Harahab (2010) in Kecamatan Gending, Kabupaten Probolinggo (Rp 95.5 million per ha per year); Suzana et al (2011) in Desa Palaes, Kecamatan Likupang Barat, Kabupaten North Minahasa (Rp 10.9 billion per year); and Haridhira (2012) in Benoa Bay, Bali (Rp 7 million per ha per year). However, when compared to the studies conducted in other countries, the estimation result in this study is at a moderate rate, which is higher than Hoberg (2011) in Kenya (US $ 1,092.3), but lower than Leong (1999) in Kuala Selangor, Malaysia (US $ 61,357) and Sathirathai & Barbier (2001) in Southern Thailand (US $ 27,921 per ha per year).…”

“…This technique is an alternative market approach to calculate cost incurred to make human product as imitations or substitutes for services provided by an ecosystem or measure the benefit obtained from replacing natural resource damage (Kaval, 2010). Referring to Suparmoko (2006) and Suzana (2011) the value is estimated based on the cost incurred for the construction of a water break and coastal protection from the danger of abrasion. The estimated cost is obtained from the professional assessment conducted by an expert.…”

“…In the implementation of ecosystem service measurements constrained by inconsistent methods [13], as a result when there is damage caused by humans both individually and in groups, the government cannot claim losses caused by such destructive activities based on market value and not marketvalue.The important value of ecosystems besides can be done with the ecological approach also through economic valuation of each function of biotic and abiotic components [14], the value of mangrove ecosystem services is mostly done through direct and indirect benefits approach, among others, Suzana et.al. [15], Saprudin and Halidah [16]. Direct benefits include the value of wood as a building material and firewood, economic value of fishery (fish, shrimp, crabs), value of leaves and fruit of mangrove.…”

Economic Valuation of Mangrove Forest at Taman Ayu Village, West Lombok Regency

“…The community does not realize that the presence of mangroves can provide a large economic value compared to its destruction [8]. These economic values can be obtained from the value of direct benefits, indirect benefits, option values and existence values [9][10][11]. The economic value of the direct benefits of mangroves is derived from fisheries, medicines, animal feed, salt, tourism, education and so on.…”

“…The economic value of the direct benefits of mangroves is derived from fisheries, medicines, animal feed, salt, tourism, education and so on. The economic value of mangrove indirect benefits can be obtained from ecosystem services [9,12] and the physical function of mangroves as a deterrent to abrasion and waves [7,9,12]. The option values of mangroves can also provide economic benefits such as genetic resources [13].…”
