Penelitian ini bertujuan untuk menentukan tingkat keberlanjutan setiap domain atau aspek dalam EAFM dan menentukan tingkat keberlanjutan kegiatan perikanan tuna di Kabupaten Pulau Morotai. Metode pengambilan data dilakukan dengan metode survei dengan cara wawancara/kuesioner dan FGD (Focus Group Discussion). Penentuan jumlah sampel menggunakan purposive sampling. Dengan analisis pendekatan EAFM, nilai komposit rata-rata seluruh domain berkisar antara 60-80 yang mencerminkan status dan kinerja sumber daya perikanan tuna yellowfin di Kabupaten Pulau Morotai yang baik dalam tingkat keberlanjutannya dengan menerapkan prinsip-prinsip EAFM. Namun, masih ada sejumlah indikator di setiap domain yang memiliki skor rendah sehingga diperlukan upaya untuk meningkatkan manajemen.EVALUATION OF TUNA FISHERIES MANAGEMENT BASED ON ECOSYSTEM APPROACH IN MOROTAI ISLAND DISTRICTS. This study aims to determine the level of sustainability of each domain or aspect in the EAFM and determine the level of sustainability of tuna fishery activities in the Morotai Island Districts. Methods of data taking was carried out with survey method by means of interview/questionnaires and FGD (Focus Group Discussion). Determination of samples quantity used purposive sampling. By the EAFM approach analysis, the average composite value of the entire domain was range of 60-80 which reflects the status and performance of yellowfin tuna fisheries resources in Morotai Island Districts was good in its level of sustainability by applying EAFM principles. However, there were still a number of indicators in each domain that had a low score so efforts are needed to improve management.

The water of West Ternate Island is open waters which are very dynamic oceanographic conditions. One of them is ocean waves that are strongly related to wind friction. This study aims to analyze the height and wave period that occurred in the western part waters of Ternate Island based on wind data for 10 years. It is expected that the results of this study will be useful for policymakers in the sustainable management of coastal areas in Ternate City. This research used Wilson Method to estimate the wave height in four seasons.  The data collected includes the maximum wind direction and speed during the period 2009-2018 obtained from the Meteorological and Geophysical Station of Baabullah Airport, Ternate City. Wind data will be transformed to stability correction and wind stress factor to determine height and period of wave. The results showed that in The West Season and Transition Season 1 (TS 1), the wind direction is more dominant moving from the Northwest to the Southeast with an average maximum speed of 17.71 knots. During the observation year, significant wave height (Hs) formed in the Western Season period as high as 1.25 m – 2.75 m while in Transition Season 1 the wave height was between 1.0 m – 2.31m. While in the Eastern Season period the wave height that occurs ranges from 0.61 m – 1.55 m and in the MP2 period ranges from 0.67 m – 1.43 m. In the Western Season, the wave period ranges from 4.67 – 6.82 seconds, and in Transition Season 1 between 4.45 – 6.44 seconds. While in the eastern season the wave period ranges from 3.29 – 4.89 seconds and in Transition Season 2 (TS 2) ranges from 3.43 – 4.68 seconds.
