of cargo arrangement so can they impact to quality stability of fishing vessel. The aim of this research is design and stability analysis Bulukumba purseseiner with three conditions cargo arrangement and two fishing seasons (peak fishing season and scarcity fisihing season). This research is done at Bulukumba regency, South Sulawesi province in February until April 2013 with measurements, observation and interview related of main dimension and cargo arrangement of Bulukumba purseseiner in field. Hydrostatic paramter analysis uses naval architecture formula and stability analysis uses PGZ software of three cargo arrangement conditions on two fishing seasons and then, these values will be compared with references value. The results of design analysis show that coefficient of finennes bulukumba purseseiner is Cb = 0.80 and Cp = 0.88 which its hull type bulukumba purseseiner is round bottom. Principal dimension ratio Bulukumba purseseiner have agreed with references of fishing vessel in Indonesia but it have not filled references of fishing vessel in Japan. The values of Bulukumba purseseiner stability have filled to IMO criteria of stability values. Stability of Bulukumba purseseiner on scarcity fishing season better than on peak fishing season and the best value of stability is PA-K3 condition (condition of purseseiner back to fishing base on scarcity fishing season). Key words: Bulukumba, cargo arrangement, design, purseseiner, stability ------- ABSTRAK Kabupaten Bulukumba merupakan salah satu daerah pembuatan kapal kayu dan masih besifat tradisional.

UNJUK KERJA SLURRY ICE REFRIGERATOR BERBAHAN BAKU AIR LAUT DI PERAIRAN TROPIS (The Performance of Slurry ice Refrigerator with Sea Water Raw Material in Tropical Area)

Fish is perishable food. Quality of fish, especially the freshness level will drop significantly if it is not treated quickly and properly. The general method used in fish handling on fishing vessels is cold treatment such as ice cube, ice flake, ice tube, and slurry ice. Usage of slurry ice in Indonesia has not been applied due to high cost of refrigeration slurry ice unit, even though slurry ice has many advantages such as quick cooling, low operating cost, easy operation, and adaptable size. The objective of this research was to determine performance of slurry ice refrigerator (SIR) using sea water as raw material in tropical area. This unit can produce slurry ice for fish handling on fishing vessel. An experimenta lmethod was applied in this research. The results showed that SIR could reach temperatures of -60 C with no-added load, and -40 C with load.

ASPEK KESELAMATAN DITINJAU DARI STABILITAS KAPAL DAN REGULASI PADA KAPAL POLE AND LINE DI BITUNG, SULAWESI UTARA (Safety Aspects Pole and liner From Ship Stability and Regulation Point of View in Bitung, North Sulawesi)

ABSTRACT Has become a common understanding that fishing is a risky job, so the safety aspects on board is an important factor that must be considered. Fishing vessels should also be supported with design and good stability, so that fishing activities can run smoothly and avoid the danger of accidents. Pole and liner in Bitung is quite varied and the ships were built in traditional dockyard and not based on the calculation and construction planning and design. One of the instruments on fishing vessel operational safety assurance is the implementation of the regulation, both nationally and internationally. At the international level, many regulations governing the safety of the ship in respect of fish. While national regulations relating to the safety of fishing vessels has not been consistent and in harmony, hence the assessment regulations relating to fishing vessel safety improvement needs to be done to determine the extent of the responsibility of government and the extent of the application of the existing rules. The general objective of this study was to determine the safety aspects of pole and line vessels, while the specific goal are: (1) review and analyze to get the quality stability of the ship (2) identify and assess safety-related regulatory review pole and line vessels in Bitung. The results showed that the quality of the stability of the vessel pole and line in the four conditions of the charge distribution in a state of good stability. It is represented by the value of all the parameters that are above the standard value IMO. In the simulated load conditions, the maximum GZ value at the time the vessel is in operation, while the GZ smallest value in an empty load case ship condition. There are seven international policy and five national policies relevant to the safety of fishing vessels. International policies clearly have established the safety of the ship and crew of fishing vessels, but implementation at the national level is still lacking and not aligned. Keywords: pole and liner, quality stability, regulation ------- ABSTRAK Telah menjadi pemahaman umum bahwa kegiatan penangkapan ikan merupakan suatu pekerjaan beresiko, sehingga aspek keselamatan diatas kapal merupakan faktor terpenting yang harus diperhatikan. Kapal ikan juga harus didukung dengan desain dan stabilitas yang baik, sehingga kegiatan penangkapan ikan dapat berjalan lancar dan terhindar dari bahaya kecelakaan. Armada kapal pole and line di Bitung cukup bervariasi dan kapal-kapal tersebut dibangun digalangan tradisional yang tidak berdasarkan perhitungan dan perencanaan konstruksi dan desain. Salah satu instrumen dalam jaminan keselamatan operasional kapal ikan adalah pelaksanaan peraturan, baik nasional maupun internasional. Pada tingkat internasional, banyak regulasi yang mengatur berkenaan dengan keselamatan kapal ikan. Sementara peraturan nasional yang berkaitan dengan keselamatan kapal ikan belum sejalan dan selaras, karenanya pengkajian regulasi terkait dengan peningkatan keselamatan kapal ikan perlu dilakukan untuk mengetahui sejauh mana tanggung jawab pemerintah dan sejauh mana penerapan aturan yang ada. Tujuan umum dari penelitian ini adalah menentukan aspek keselamatan kapal pole and line, sedangkan tujuan khususnya adalah: (1) mengkaji dan menganalisis untuk mendapatkan kualitas stabilitas kapal (2) mengidentifikasi dan mengkaji tinjauan regulasi terkait keselamatan kapal pole and line di Bitung. Hasil penelitian menunjukkan bahwa kualitas stabilitas kapal pole and line pada empat kondisi distribusi muatan dalam keadaan stabilitas yang baik. Hal ini diwakili oleh nilai semua parameter yang berada di atas nilai standar IMO. Pada kondisi simulasi muatan, nilai GZ maksimum berada pada saat kapal beroperasi, sementara nilai GZ terkecil pada kondisi kapal muatan kosong. Terdapat tujuh kebijakan internasional dan lima kebijakan nasional yang relevan dengan keselamatan kapal ikan. Kebijakan internasional jelas telah menetapkan keselamatan kapal dan awak kapal penangkap ikan, tetapi implementasi di tingkat nasional masih kurang dan belum selaras.

STABILITAS STATIS KAPAL STATIC GEAR DI PALABUHANRATU (STUDI KASUS KM PSP 01)

This paper discusses on the static stability performance of a fishing vessel operated static fishing gear. A fishing boat named as KM PSP 01 was chosen as an object of this research. The objectives of this research were to analyze the static stability performance and work comfortability aboard the vessel. The result showed that KM PSP 01 was good enough for operating static fishing gear, the static stability of the boat is considered to be good with enough righting arm to upright the boat after roll to certain maximum angle. Hull of the boat considered as slim. Short rolling period i.e. 3.467 sec. considered as not so comfortable for working on deck but still safe in fishing operation.
