| Abstract | Mangrove, estuary and lagoon ecosystem can be used as the aquatic organism habitat. These ecosystems also have good suitability to support activity of silvofishery system. àEmpang parit as a model of silvofishery using àthe integrating between the conservation activity of mangrove and aquatic ecosystem with increasing of benefit income for àfisherman. This research aimed to analyze the model and pattern of empang parit, environment factor of empang parit and benefit cost analysis of empang parit. The research used vegetation analysis, water quality analysis, cash flow analysis, satellite image analysis, and geographical information analysis. àThe research explained àthat empang parit àrequired water àtemperatur between 29 â 32.6oC, water brightnes between 30 â 60 cm, water salinity between 15 -32 ppt, pH between 7 â 81 and dissolve oxygen between 3.9 â 8.3 mg/L.The empang parit also need àBruguiera gymnorrhiza, Heritiera littoralis and Excoecaria agallocha, Rhizophora mucronata and àRhizophoraàapiculate to cover empang parit system. àAnd empang parit gave postive economic value based on value ofàNPV between 2.754.703âÂÂ3.871.542 IDR, IRR between 21âÂÂ48 and àR/C between 2.26âÂÂ2.32.Keywords : ààààEmpang parit; àsilvofishery system; àeconomic valuation;àwater quality; àmangrove coverageà|
