The fishing boat fleet, seeking for a kind of fishing gear. One of the most common fishing boat types in Bitung Oceanic Fishing Port is pambut (Pumpboat). The researcher is concerned about the effect of engine power difference on speed and fuel consumption of pakura boats. The objective of the research is to determine the speeds of boat in the operation and to determine the average consumption of fuel of engine by in different horse power. The method used in this research is the experimental method. The primary data is stored at the same time as the observations performed by the target system. The effect of engine throttle opening with the speed and fuel consumption is analyzed by a regression that uses Microsoft excel. The relation data is denoted in interpretation with table, grafic and a form of a sentence. In conlusion, the best speed of the 6.5 HP is 7.57 knots while the 9 HP powered are 8,96 knots. The best fuel consumption of engine that powered 6.5 HP is averaged 2.87 l/hr while the engine powered 9 HP an average of 4.40 l/hr.

Abstrak
Armada penangkap ikan, mengusahakan berbagai macam jenis alat tangkap ikan. Salah satu jenis kapal penangkap ikan yang umum terdapat di Pelabuhan Perikanan Samudera Bitung yaitu pambut (Pumpboat). Peneliti merasa  perlu dilakukan penelitian tentang Studi tentang pengaruh perbedaan daya mesin terhadap kecepatan dan konsumsi bahan bakar minyak pada perahu pakura. Adapun tujuan penelitian adalah untuk menentukan kecepatan terbaik perahu pakura dalam operasi penangkapan ikan dengan daya mesin yang berbeda dan menentukan rata-rata konsumsi bahanbakar yang dibutuhkan perahu pakura dalam melakukan operasi penangkapan ikan dengan daya mesin yang berbeda. Data primer yaitu data yang diambil langsung pada saat pengamatan yang dilakukan dengan cara target system. Hubungan bukaan gas dengan kecepatan dan konsumsi bahan bakar minyak (BBM) akan dianalisa dengan analisa regresi yang menggunakan Microsoft excel. Data hubungan tersebut digambarkan dalam bentuk tabel dan grafik yang di interpretasi dalam bentuk kalimat. Kecepatan yang terbaik pada mesin yang berdaya 6,5 HP adalah 7,57 knot sedangkan pada mesin yang berdaya 9 HP adalah 8, 96 knot. Konsumsi BBM yang terbaik pada mesin yang berdaya 6,5 HP adalah rata-rata 2,87 l/jam sedangkan pada mesin yang berdaya 9 HP rata-rata 4,40 l/jam.
