Abstract

 The Seagrass bed ecosystem is one of the essential ecosystems besides mangroves in the coastal area of ​​Pundata Baji Village. However, the knowledge of coastal communities (fishermen) on the Pundata Baji regarding seagrass ecosystems' physical, ecological, and socio-economic roles is still limited. In addition, these coastal communities do not yet have the knowledge and skills to restore the damaged seagrass habitat (degraded). Therefore, awareness-rising programs and training efforts are needed, as well as demonstration plots regarding community-based seagrass restoration technology through transplantation (planting). Seagrass transplant trials used the Staple, the Frame/TERFS, and the rock anchor methods. The three transplantation methods introduced are simple, inexpensive, easy to learn, and applicable to the target group. Community understanding and awareness of the importance of seagrass ecosystems have increased after attending counseling and training. In addition, coastal communities have skills in seagrass transplantation after attending the training. Another target achieved from the seagrass transplant pilot activity is the availability of alternative fishing areas in the seagrass planting area for fishermen groups in the Pundata Baji coastal area.

Abstract

Seaweed cultivation is an alternative community livelihood that potentially helping to reduce pressure on coral reefs in the area of Raja Ampat Archipelago. This study was aimed to conduct an oceanographic analysis of the waters of Meosbekwan Island (Raja Ampat Regency) for the suitability of seaweed cultivation. Oceanographic data collection was carried out at three points (M1, M2, and M3) on the western side of Meosbekwan Island. Analysis of suitability for aquaculture was initiated with an analysis of key parameters, i.e., depth, protection and shipping traffic. The suitability analysis was followed by an analysis of the oceanographic parameters of the waters by weighting them using a ranking system. Furthermore, the final stage of suitability analysis was to evaluate the feasibility level of seaweed cultivation. The results showed that the depth of the waters on the western side of Meosbekwan Island ranged from 1.3 m – 5.8 m with an average depth of 1.5 m in the south (M1), 2.2 m in the middle (M2), and 3.9 m to the north (M3). Wave height during the study ranged from 0.1 – 0.3 m with an average value of 0.25 m at all points. The velocity of the water currents ranged from 0.08 – 0.25 m/s. The salinity of the waters was relatively homogeneous (30 - 31 o/oo). Water temperature also has small and relatively homogeneous variations with a range of 30 - 31˚C. The brightness of the waters ranged from 2.5 – 3.5 m. The bottom of the waters on the west side of Meosbekwan Island generally consists of coarse sand, rubble, and seagrass vegetation Enhalus acoroides and Cymodocea sp. In general, the oceanographic conditions of the waters are suitable for the life and growth of seaweed. The results of the location suitability evaluation indicated that the waters on the western side of Meosbekwan Island were technically feasible to serve as a location for seaweed cultivation.
