The Handling System of Product and Existence of Waste Components in Fishing Operation of Tuna in Bitung, North Sulawesi

<p>Handling in fishing vessel is urgent to maintaining the quality of tuna products, while the existence<br />of waste components can bother the performance of fishing operations. The aims of this research are to<br />evaluate the handling system of tuna products in fishing vessel and to analyze the influences of fishing<br />operation to the existence of waste components. This research methods are no control chart and regression<br />model approach. Research result shows that the handling system in the fishing operation of tuna in Bitung<br />is not optimum. But the quality of tuna products which landed is still in controlled as shown by amount<br />of rejecting products in UCL-LCL range (0 – 3,63 reject products/processing). The influence of amount of<br />tuna caught per setting (X) to existence of bait waste (Y) formulated with model Y = - 1,176X+37.794, the<br />influence of amount of tuna products (X) to the existence of ices remained Y) formulated with model Y =<br />- 0,002X + 62,226, and also the influences of fishing operation which deputized by the amount of ABK (X1)<br />and number of operating days (X2) to the existence of freshwater remained (Y) formulated with model Y<br />= 50,000X1-23,704X2+288,889. The significant impacts are only the influence of amount of tuna products<br />in existence of ices remained (sigh = 0,036) and number of operating days of the existence of freshwater<br />remained (sigh = 0,037).<br />Keywords: Bitung, waste components, handling system, tuna
