Abstract

The utilization of renewable energy is experiencing significant growth, with wind turbines emerging as a key solution for generating environmentally friendly electricity. However, the efficiency of wind turbines is highly dependent on their operational parameters, such as wind speed, blade size, angular velocity, and torque. This research aims to optimize the operational parameters of small-scale wind turbines using an XGBoost-based Machine Learning model and an L-BFGS-B algorithm-based optimization method. A simulation dataset was generated based on the physical equations of wind turbine power and a MATLAB Simulink model, incorporating added noise to approximate real-world conditions. The XGBoost model was trained to predict the turbine's output power based on its operational parameters. Subsequently, an optimization method was employed to identify the parameter combination that yields maximum power. The experimental results demonstrate that the model exhibits strong performance, characterized by a low Mean Squared Error (MSE) and a high R-squared score. The optimization process successfully achieved a significant increase in power output compared to the initial configuration. Through this approach, wind turbine systems can operate more efficiently and generate optimal electrical power. This study contributes to the advancement of artificial intelligence-based optimization strategies for renewable energy systems.

Abstract

This study investigates the application of renewable energy—specifically solar panels and wind turbines—in the electrical systems of fishing vessels. The research methodology includes literature review, power demand analysis, simulations, and experimental trials on a prototype fishing vessel. The findings demonstrate that integrating renewable energy systems can reduce fuel consumption by up to 30% and significantly improve operational efficiency. The adoption of a hybrid solar and wind energy system enables fishing vessels to remain at sea longer without complete reliance on fossil fuels. This study makes a notable contribution to the field of marine electrical systems and renewable energy by developing and validating a sustainable, energy-efficient onboard power system through a comprehensive empirical approach—ranging from technical design and simulation to field implementation. Key outcomes include a 30% reduction in fuel use and an increase in system efficiency to 85%, offering a practical solution for lowering operational costs among small-scale fishermen. The research also advances theoretical understanding of renewable energy integration in the maritime sector, which has predominantly focused on large commercial vessels. The incorporation of lithium-ion–based energy storage systems in small Indonesian fishing vessels presents a novel approach with significant development potential, particularly in addressing geographic and energy access challenges in remote coastal communities. These results provide a foundation for formulating government policies on subsidies and incentives to support the transition to green energy in the national fisheries sector.

Abstract

Mastery of mechatronics skills is a key factor in enhancing the competitiveness of vocational high school (SMK) graduates, especially in the era of Industry 4.0. This study aims to develop the mechatronics skills of SMK Puger students through a Remotely Operated Vehicle (ROV) project. The method used in this research is a project-based learning approach, involving the design, assembly, and testing of the ROV directly by students. The results show that the implementation of this project improves students' understanding of electrical systems, microcontroller programming, and mechanical assembly skills. Furthermore, this project also enhances teamwork and problem-solving skills. Thus, the development of mechatronics skills through the ROV project can be an effective alternative in improving the quality of learning in vocational schools. This research makes several significant contributions to vocational education, particularly in enhancing students’ mechatronics competencies through a practical and innovative learning model. These findings suggest that integrating PjBL and technological innovation in vocational education is a viable and impactful method to enhance student learning outcomes and workforce readiness

Abstract

Overhead conveyors are designed to facilitate the transfer of material from one location to another. One aspect that needs to be planned is the vertical lifting structure, which is the initial loading process the material is attached to the trolley at a higher level of overhead conveyor. By design this tool can facilitate material loading work, as it reduces the possibility of product damage, reduces risk of worker exhaustion and smoothest the production flow. Loading analysis is carried out using FEM-based software to determine the strength of structures on design concepts. Structural strength analysis recorded minimum safety factor is 3,928 at the end of the hoist profile, a maximum von misses stress value of 63,188 MPa at the target frame point of the long profile hoist and a limits displacement value of 0,238 mm on the loading rail. The results of the structural buckling analysis with a limit of 1 load on the design concept were 350,589 times the load.

Abstract

In the steel structure fabrication industry, girders play a crucial role as supporting beams during construction. The girder's components include end plates and beams, with the end plate serving as a critical connection point for the beam to the column. Welding at this juncture demands careful consideration. This analytical research focuses on the impact of multiple repair welding and quenching temperatures during the heat straightening process on the toughness and microstructure of HSLA SM490YA material, utilizing FCAW welding. To assess the effects of multiple repair welding, the study compares different repair scenarios—welding without repair, two repairs, and three repairs, all performed at a 50% depth. Subsequently, the heat straightening process occurs at a temperature of 650ºC on the repaired material. Post-heat straightening, quenching is carried out with temperature variations of 650ºC, 475ºC, and 300ºC. The findings indicate that the repair process during welding and subsequent quenching after the heat straightening process leads to a decrease in toughness values. This results in a finer grain size, with the material phase predominantly composed of pearlite. These research outcomes should be carefully considered by industry professionals, particularly in critical connections, when determining quenching temperatures after the heat straightening process in repair procedures.

Abstract

The wrapping up and portray fabricating handle may be a organize of venture work at PT. Lintech Duta Pratama. Disgraceful portray forms result in absconds. Items that have absconds require repair so they can at that point be sent to clients. Rehashed repair forms cause expanded handle costs and obstruct item conveyance. In this manner, to get great item quality and diminish handle costs, inquire about to obtain ideal parameter settings is required. The method parameters considered are surface harshness, substrate temperature, and sort of abrasive fabric. The experimental design used is the taguchi method in the form of an orthogonal matrix . From the exploratory comes about, the ideal combination of handle parameters for prepare costs was gotten, to be specific surface harshness at level 1 with a esteem of 50 μm, temperature at level 2 with a esteem of 34 ° C, and rough fabric sort at level 2 with steel coarseness.
