“…The increase in river tourism demand is not anticipated with the technological advancement of river tourism boats. Most river cruises still use materials that can harm the environment [2,3,4], To make it worse, those boats also still use outboard engines, both two-stroke and four-stroke engines, as seen in Figure 1. The working system of the outboard engine is to carry out the combustion process of the fuel used.…”

River cruise tourism in Indonesia has a moderately high potential as there are so many rivers in Indonesia that offer beautiful natural and urban views. However, majority of river cruiser boats still use outboard engines, both two-stroke and four-stroke combustion engines. The working system of the outboard engine is to carry out the combustion process of the fuel oil. This combustion process usually has a loud sound, leading to noise pollutants that can harm the environment and make passengers uncomfortable. Burning fossil fuels also causes the residual compounds that increases environmental pollution, especially carbon emissions. In this paper, an analysis will be carried out on the operational costs of a river cruise ship with electric paddle wheel propulsion. With a boat design with an LOA size of 5.4 m, breadth of 1.4 m, height of 0.8 m, draft of 0.3 m, and CB of 0.68, the paddle wheel diameter is 70 cm, blade width of 30cm, and 6 blades. The motor used to drive the paddle wheel has a power of 672.69 watts, with a battery capacity of 100 Ah. According to operational planning, benefits will be obtained, including zero carbon emissions, no noise and operational benefits can be up to 90% greater when compared to the out-board engine drive.

With the increased emphasis on the use of recyclable bio-based materials and further understanding of the mechanical properties of laminated bamboo, the development of a new generation of low-cost bamboo-based composites for ship structure has generated a significant interest. Laminated bamboo composites comprising Apus bamboo (Gigantochloa apus) and Waru fiber at different layer orientations were investigated to obtain the mechanical characteristics. The influence of different laminate directions was studied through several methods of mechanical testing, including impact tests using ASTM D256, bending tests using ASTM D7264, and tensile tests using ASTM D3039. Results showed that material strength properties could be improved by using on-axis direction (0°). The bamboo composites with unidirectional (0°) laminate direction exhibited superior mechanical properties to bidirectional laminate directions (45°/−45° and 0°/90°). The addition of Waru fiber improved the mechanical properties of the currently developed material; that is, bending strength increased by about 3.17–14.18% and tensile strength was in the range of 4.88–20.28%. Only those composites with 0° and 0°/90° layer orientations fulfilled the Indonesian Bureau Classification strength threshold.

The need for wood in the ship building industry continues to grow every year. An alternative raw material is needed to replace wood at a more affordable price, namely, bamboo laminated boards. However, bamboo has a weak connection between its segments, with a maximum length between components of less than 40 cm. To reduce these weaknesses, the connection between bamboo segments with laminated boards is carried out as follows: scarf joint, butt joint, finger joint, desk joint, and tongue and groove joint. The study aims to determine the connection’s effect on each connection variation’s strength. Tensile tests and bending tests were carried out on the test specimens. The average results obtained were quite varied for the tensile test, which were in the range of 81.36–118.62 MPa, while the results of buckling test were in the range of 395.28–475.89 MPa. This study revealed that the connection of the specimen with seven layers had a value of 118.62 MPa in the tensile strength test and 475.89 MPa in the buckling strength test, while 3 layers finger joint samples with the lowest buckling tensile strength value had a value of 81.36 MPa tensile strength and 395.28 MPa bending strength.
