PEMODELAN HYBRID BIOEKONOMI UNTUK PENGEMBANGAN KAWASAN KONSERVASI LAUT DI PULAU-PULAU KECIL

Degradation of fisheries resources in Raja Ampat regency, province of
West Papua, in the coast and marine areas poses a serious problem. This pressure
is aggravated by the lack of natural resources management system based on
scientific studies. This research tries to answer these problems by developing a
hybrid bioeconomic modelling to safeguard of MPA management in small islands
areas to support community wellfare; and will be achieved through four main
objectives, namely: (1) to analyze general condition of marine resources, marine
protected area (MPA) and communities; (2) to analyze performance baseline
(condition without MPA) of capture fisheries under different regime of MSY,
MEY and open access and compared these regime with the condition after MPA
applied; (3) to analyze social economics impact of MPA on fisherman; and (4) to
formulate hybrid bioeconomic modelling based on the dominan factor of MPA
management. Economic parameters used consist of price, cost, and input
production. The model estimates the following biological parameters i.e, r (growth
rate)=0.6314 (%), q (coefficient of fishing catchability)=0.0066 (per trip), and K
(carrying capacity)=41.6662 (ton). The findings indicate that capture fisheries in
Raja Ampat have not in overfishing yet. Effort level under open access regime has
been analyzed at 78.11 trip per week, MSY regime at 47.92 trip per week and
MEY regime at 39.06 trip per week. At sole owner (MEY) regime, economic rent
could be generated as much as Rp. 4,040,425.19 per week. This is the highest rent
compared to MSY regime (Rp. 40,825,341.52 per week) and open access regime
(Rp. 0 per week). Actual production and economic rent by MPA are higher than
without MPA. Implementing MPA would call for reduction of effort, which
indicates that MPA would make fisheries management more efficient. Total area
of MPA has significant influence on production, effort and economic rent. There
is a maximum size of MPA to achieve maximum economic rent, it means “bigger
is better” in case of MPA would not relevant. MPA principles based on spill over
effect was modeled using spill over coefficient i.e, β model. The model shows that
increase in β will increase of economic rent (β of 0.1 has harvest (h)=4.71 tones
per week and β of 0.5 to be increased h up to 7.78 tones per week). The analysis
using β model has shown better performance than σ model (size model). It means
spill over effect management is more efficient for effectiveness of MPA. Spill
over effect or β model named by Haryani-Fauzi model or HF model as novelty of
this research has shown at MEY, production and economic rent bigger than σ
model. MPA increased fish cath and fisherman income. Rent capture mechanism
of MPA benefits could be used by means of payment for environmental services
(PES). Three options of MPA model consist of: government lead, NGO lead and
community lead. MPA in Raja Ampat, firstly managed by government lead and
changed to NGO lead, then respectively will be changed to community lead.
