Abstract:
The mangrove forest area of PT. SILO (Sebuku Iron Lateric Ores) Kotabaru company has a
mining concession area of ± 9,771 ha, around ± 85 ha of the areas are mangrove forest area
that have been freed from mining activities. However, this company plans to manage this area
to be an ecotourism forest in order to provide the economic value around the communities.
This study aims to investigate the economic value of mangrove forest areas based on three
criterions of benefit: (1) direct, indirect, and optional benefit. The primary data were collected
using several method: survey, observation, and interviews with fishermen and communities
around the area. A total of 22 respondents of 150 fishermen were interviewed randomly: 15
fish/shrimp fishermen, 2 clam catchers, 4 mud crab catchers, and 1 mud crab cultivator. The
collected data were analyzed descriptively and total economic valuation analysis using
quantification technique of market prices, indirect prices, and replacement values. The results
showed the economic value of the mangrove forest area for direct benefit was IDR
10,082,232,500 year-1
(shrimp IDR 9,411,573,000; fish IDR 265,717,000; clam IDR
99,242,500; and mud crabs Rp. 305,700,000. The indirect benefit was Rp. 10,578,857,143
year-1
and as an abrasion barrier was 174,082,920 year-1
, while the value of the selected
benefits was Rp. 17,901,000 year-1
. In conclusion, the value of strategic developed areas is
literally integrated mangrove aquaculture (silvofishery) and mangrove ecotourism.
