Abstract

The fishermen in Sendang Biru, Malang, East Java Province, Indonesia, using boat <= 5 GT, specifically an outrigger boat with 10,6 m Length of Overall (LoA), 1,3 m Breadth (B), and 0,7 m Depth (D), have experienced low priced fish catches for many years caused by low quality of fish handling on board. In this research, the researcher overcomes the problem by designing the solar powered cooling engine (SPCE) to maintain the caught fish quality on boat <= 5 GT, especially the boat with outrigger and size as previously mentioned. Meanwhile, the outrigger boat as mentioned above has limited in term of its space and its capacity on board. The research designed the SPCE that fitted to space and capacity of the outrigger boat. The stability of the boat had been analyzed by using IMO resolution on "IMO A.749 (18) Chapter 3". The result of the analyses showed that the SPCE designed met the IMO criteria applicable to all ships, which has GZ Max 0,492 m at 25.5°, and as the general arrangement of the SPCE on the boat, the SPCE device put in the middle of the boat while in the back part of the boat is fisher working area.

Abstract

The tuna handlines operated by some fishers from Southern Malang in the Indian Ocean can be categorized as a type of static fishing gear. The stability of their small-sized vessels becomes critical when a large-sized tuna is caught by the handline and lifted with the help of a line hauler installed onboard, i.e., the floating angle tolerance may be exceeded.   This study aims to determine the angle of inclination of a 9 GT boat when a line hauler is operated onboard.  The research was carried out in June 2016 by measuring the principal dimensions of a fishing boat, FV Cahaya 01, in Pondok Dadap Fishing Port, Malang.  The principal dimensions are length overall (LOA), length before perpendicular (LPP), breadth (B), and depth (D) Data on the boat's principal dimensions, lines plan, and hull shape were used for the boat’s stability calculation.   The studied boat's buoyancy center is located at 0.27 m in front of the midship and the TCP is 0.315. The maximum load of the line hauler was 211.253 kg, and the inclination angle during the hauling process was 3.520.  The installation of the line hauler on the fishing boat creates a new acceptable stability of the boat.
