Abstract

In 2004 at least 230,000 people were victims of the Aceh tsunami disaster. To prevent the recurrence of many victims, the Aceh government held an evacuation exercise in 2008. To improve effectiveness dan reduce the cost reduction during evacuations drills, simulation is the best option. Agent-Based Modeling is a simulation program that was employed for tsunami evacuation in Aceh. This study on tsunami evacuation using agent-based modelling presented and evaluated the different control parameters that affect the evacuation rate. Evacuation scenario during day or night has different environmental, agent base, road modelling, and population approach. The Road Network Model has explained that to analyze the effect of agents in the evacuation process, resident agents are presumed to know the direction and shortest path to the nearest evacuation points. This simulation designed in Netlogo is also able to assess the congestion possibility on the road network. The road network emphasized the different scenarios to discover the possibility of congestion points. Nighttime is proven to be the best scenario for performing the evacuation in the simulation. The key reason to select the night scenario is to maximize the effects of an evaluation of the road network. In addition, simulation using night scenarios is also expected to raise people’s awareness.

Abstract

Agent-Based Modeling and Simulation (ABMS) was implemented to build and develop an evacuation simulation model. In this research, ABMS is simulated in several evacuation scenarios with an output: the evacuation rate of two different decision choice evacuation modes (walking or driving to the evacuation points). The result of this tsunami evacuation simulation shows that the decision choices on the evacuation mode are highly correlated to the evacuation rate. Observed in the simulation that there is a typical choice that leads to the higher evacuation rate, the choice is by maximizing the pedestrian agents on the population distribution.

Abstract

An investigation of marine UAV performance with various designs have done successfully. The analysis was based on resistance criteria identification both aerodynamically and hydrodynamic. The calculations were conducted with the assistance of image processing as the experimental attempt and High-Fidelity Computational Fluid Dynamics (CFD) software code to simulate the fluid flow on the fuselage designs, pontoons, and image processing. Both methods compared to acquire the silver line in which way they can collaborate to create new way of testing. Furthermore, mathematical calculations and Image processing works refereeing were also performed as the attempt for validations and conclusion

Abstract

Unmanned Aerial Vehicles (UAVs) are currently experiencing rapid development for both general and military applications. Among the various types of UAVs, the quadcopter stands out as a multirotor aircraft capable of vertical take-off and landing (VTOL). The primary factors affecting the imbalance of a quadcopter typically include payload weight and wind disturbances. The payload carried by the quadcopter can lead to instability during flight, while wind, as an external factor, significantly affects the aircraft’s stability. Irregular wind direction and speed can shake the quadcopter's body, resulting in unstable flight conditions. Developing a quadcopter that remains stable during flight, selecting an appropriate control method is crucial to achieve the desired balance. One effective approach for controlling brushless motor speed is the Proportional-Integral-Derivative (PID) control method. Among various PID tuning methods, the Ziegler-Nichols method is considered effective for this application.Based on this study, the control of the roll (ɸ) and pitch (θ) angles of the quadcopter yielded the following PID parameters: Kp = 15, Ki = 0.55, and Kd = 0.13. The results indicate that the quadcopter has not yet achieved perfect stability in flight. This research represents an initial stage in designing a quadcopter balance control system using the Ziegler-Nichols PID tuning method.

Abstract

In the process of shipbuilding production and repair, deformation is sometimes encountered due to several factors, starting from load pressure, pulling, lifting, and welding processes. A fairing process is carried out to overcome the plate deformation, in which the plate is heated and cooled simultaneously. The method used in this research is direct time measurement during the fairing process on test plate specimens with variations in the depth of deformation curvature. The data obtained, processed, and analyzed to obtain an estimate of the fairing processing time the longer the fairing process takes, following the equation Y = 41.285X + 530.94, where X is the deformation angle, and Y is the estimation fairing processing time area per half square meter.

Abstract

An investigation into the hydrodynamic force and seakeeping of single-to-twin after ship hull (STASH) and multi-hull geometry was done successfully. STASH is characterized by its monohull-shaped design in the fore part and twin hull in the rear part creating unique performance, especially seakeeping which being the focus study to provide seaworthiness. The method of accomplishing this study was through computer simulation using Maxsurf: Motion for seakeeping and hydrodynamic force analysis. The overall results were compared with published data and mathematical models for validation purposes. The results are believed to be useful for the development of the ship design and performance.
