Abstract

Ship placement along a ferry route is commonly not similar according to tonnage and cargo capacity, such as what happened on the ferry route between Bira and Pamatata in South Sulawesi. The Bira-Pamatata ferry route is operated by three ferries, each with a different load capacity and tonnage of KMP Balibo 540 GT, KMP Kormomolin 884 GT, and KMP Bontoharu 1053 GT. Variations in load capacity and ship operating costs will undoubtedly affect the income disparities between ferry operators. The length of the distance of the ferry route and the number of frequencies also have an impact on how much a ship costs to operate. The purpose of this research is to establish how the length of the distance of the ferry route and ship frequency affected the operational cost for the ship of different sized. The benefit of this research is can be applied to estimate the optimum ship size regarding operational cost for a particular trajectory distance and frequency. The analysis's results establish that ship operational costs are influenced by distance. The cost of operating will rise linearly as the length of the distance of the ferry route increases. There is a rise in operational cost (Rp/SUP) for variations in distance of Rp.262.40 for KMP Balibo, Rp.213.13 for KMP Kormomolin, and Rp.234.49 for KMP Bontoharu for each 1-mile added. The ship's operating time is affected by distance as well. The frequency that can be reached by ship decreases as the distance gets lengthy because the operating time of the ship also gets longer. Operational cost (Rp/SUP) for variations in frequency tends to decrease exponentially as a result of decreasing fixed costs. The analysis's results establish the operational cost (Rp/SUP) for the three cheapest distance and frequency variations sequential by KMP Balibo 540 GT, KMP Kormomolin 884 GT, and KMP Bontoharu 1053 GT for the 87-mile below. When the distance is 87 miles above, the graphic lines between KMP Kormomolin and KMP Bontoharu intersect at specific frequency variations, resulting in lower operational costs (Rp/SUP) for KMP Kormomolin than KMP Bontoharu.

Abstract

The Sandeq boat is a type of traditional boat used for fishing and sea transportation by the Mandar people, in the coastal area of ​​West Sulawesi. Round wood is still the main material used in making sandeq boats. The aim of this research is to determine the characteristics of sandeq fishing boats made of wood in the province of West Sulawesi. Determining of the respondent is this research is done by purposive. Analysis method is used: qualitative and quantitative descriptive analysis. The result of the research shows that there were 4 types of sandeq boats used to catch fish, namely the Pangoli types with a length 5-7 meters as much as 55,23 %, Parroppong and Potangga types with a length 7 – 11 meters as much as 41, 91 %, and Pallarung types with a length >11 meters as much as 2,86 %. The four types of sandeq boats used a combination of sails and engines as propulsion. The main construction includes: stripes (lunas), sideboards (palamma boards), ivories (tajo), deck boards (kalandara), katir beams (baratang), and masts (palayarang). The L/B of a sandeq boat average 8.23-11,27 which intends to increase if the length is added to indicate that they are appropriate for high speed boats, while the L/H   ratio of sandeq boats average 7,25-10,30 which tends to increase in length indicates that sandeq boats are lacking in terms of elongation resistance.  The B/H ratio of a sandeq boat average 0,89-0,92 which is relatively low and tends to be the same indicates that the stability of the boat is not good. This study suggests that further research are needed to do advance research on the longitudinal resistance of sandeq boats, as well as more in-depth research on the stability of outrigger boats is required.
