ABSTRACT
The stability of a ship is one of the important technical factors in supporting successful fishing operations, and ultimately improving the welfare of fishermen; therefore a study on the stability of KM. Surya Prima had been done in the village of Borgo, District of Tanawangko, Minahasa Regency. Dynamic stability is the stability of the vessel measured by giving a force at the boat to form a certain rocking angle. This stability is expressed as an area under the curve of static stability. Dynamic ship stability calculation results will be compared with the stability criteria according to the International Maritime Organization (IMO) as in Fyson (1985) through the GZ curve. From the comparison it will get the level of dynamic stability of the vessel under study. Dynamic stability parameter values of Surya Prima purse seine vessel were: A (0-300) = 0.1179 m-rad., B (0-400) = 0.1935 m-rad., C (30-400) = 0.07552 m-rad., D (Angle GZmax) = 48 097, E (GZmin) = 0.475 m, F (GM) = 0965 m.

ABSTRAK
Kestabilan kapal adalah salah satu faktor teknis penting dalam menunjang sukses operasi penangkapan ikan, dan pada akhirnya akan membantu meningkatkan kesejahteraan nelayan; oleh karena itu telah diadakan penelitian stabilitas KM. Surya Prima di Desa Borgo, Kecamatan Tanawangko, Kabupaten Minahasa. Stabilitas dinamis adalah stabilitas kapal yang diukur dengan jalan memberikan suatu usaha pada kapal sehingga membentuk sudut oleng tertentu. Stabilitas dinamis dinyatakan dalam luas area di bawah kurva stabilitas statis. Hasil perhitungan stabilitas dinamis kapal yang diukur dibandingkan dengan nilai kriteria kestabilan kapal oleh International Maritime Organization (IMO) dalam Fyson (1985) melalui kurva GZ. Dari perbandingan itu akan didapatkan tingkat kestabilan dinamis dari kapal yang diteliti. Nilai parameter kestabilan dinamis kapal pukat cincin Surya Prima adalah sebagai berikut: A (0-300) = 0.1179 m-rad., B (0-400) = 0.1935 m-rad., C (30-400) = 0.07552 m-rad., D (Sudut GZmax) = 48.097, E (GZmin) = 0.475 m, F (GM) = 0.965 m.
