Abstract

An anchor handling ship is a ship designed to support offshore operations in the form of handling offshore building anchors and carrying out activities of moving objects such as FPSO, Semi-Submersible Rigs, construction, production, and barges from one place to another where it requires bollard strength. pull which varies depending on the size of the object, besides that it is also to support other activities such as exploration and drilling. The VS 491 design type anchor handling tug supply (AHTS) vessel which has been built by a shipyard in Batam has a maximum bollard pull test of 255 tons. This paper will analyze the propeller thrust, power, and efficiency propeller before and after the installation of the Rudder Bulb (RB) respectively in free-running conditions and towing barge conditions in 50% barge conditions and full loaded capacity, as well as in draft, and Speed on certain Anchor Handling ships. The resistance of the object being towed (towing) will be calculated on the load and speed of each. By using Maxsurf, software Rhinoceros 3D, dan the Numeca CFD, the shape of the ship's hull is produced according to the original. Then validation is carried out by comparing the resistance in the calculation by Maxsurf/Holtrop and the resistance in the calculation by CFD where resulting in a difference of less than 5% so that it can be said that the form of the model is in accordance with the original shape of the ship. Based on the calculation results in the free running conditions of the Anchor Handling ship, the Propulsive Coefficient (Pc) without ESD Rudder-Bulb (RB) at speeds of 10, 12, and 16.36 knots is 0.5162, 0.5407, and 0.5769 respectively, while with ESD-RB each is 0.5008, 0.5417, and 0.5921. Comparison of the Propulsive Coefficient without ESD-RB and with ESD-RB, that at speeds of 12 and 16.36 knots, the Propulsive Coefficient (Pc) increased by 0.19% and 2.58%, respectively, but the Propulsive Coefficient (Pc) decreased by 3.08% at 10 knots. Based on the analysis that has been carried out, it indicates that the installation of the Rudder Bulb (RB) will give an increase in the Propulsive Coefficient (Pc) at speeds of 10 knots and above in free-running conditions, whereas when towing it hardly gives an increase in the Propulsive Coefficient (Pc).

Abstract

High ship propulsion performance is the main goal of designers, propeller is one component of the propulsion system that also affects the performance of the propulsion. In propeller planning, it is necessary to pay attention to the efficiency of the propeller, in addition to reducing ship operating costs and reducing CO2 gas emissions which is one of the requirements for ships built above 2013, the rules have been made into the Energy Efficiency Design Index (EEDI) standard. At this time the propeller that is widely used is the B Series propeller including the propeller design used on mini LNG ships, namely the B6.40 propeller, the B Series propeller has a pitch character from the Wageningen Propeller Series study. Innovations are made to get better propeller efficiency by varying the pitch distribution. The B6.40 propeller of the standard constant pitch type was modified to B6.40 variable pitch (high thrust). Propellers with high thrust have better efficiency especially for non-fast boats. This study was conducted to obtain the best propeller efficiency of a constant pitch propeller and three high thrust propeller units using Numeca's Computational Fluid Dynamics (CFD) numerical self-propulsion test. For validation of the simulation program by comparing the results of the open water test B6.40 Wageningen while resistance validation by comparing the ship resistance model test. The results of the self-propulsion test using Disc Actuator show that the propulsion coefficient (PC) of Modified-2 and Modified-3 high thrust propellers is better when compared to constant pitch. The magnitude of the increase in PC value reaches ± 4% higher than the constant pitch type on the Modified-3 propeller.

Abstract

Schools have used various educational approaches, such as learning models, but students’ motivation to learn mathematics is still low. This study has the following objectives: (1) to find out whether the application of Problem-Based Learning (PBL) student worksheets can increase students’ learning motivation in mathematics, and (2) to find out how students respond to the application of Problem-Based Learning (PBL) student worksheets during the learning process. The research conducted was a class action research (PTK). Students in class VIII G of SMP Negeri 8 Denpasar in the academic year 2023/2024 are the subjects of this research. The focus of the research is how students are motivated to learn and how they respond to the application of Problem-Based Learning (PBL) based student worksheets in learning mathematics. The research was conducted in two cycles, with a cycle consisting of four stages: (1) preparation; (2) action; (3) observation and assessment; and (4) reflection. The report on the results of Classroom Action Research (CAR) shows that the average value of learner motivation in cycle I is 3.35, which is included in the high criteria, while in cycle II it is 3.73, which is included in the high criteria, with an increase of 0.38 and the significance of the increase in motivation. The average learner response score was 52.8, with a standard deviation of 2.26, which showed a positive increase.
