This study examines the effectiveness of Project Based Learning (PBL) in enhancing cross-cultural communication skills within international language education programs. As globalization increases, effective communication across cultures is essential, and language programs must equip students with these skills. PBL, a learner-centered instructional strategy, integrates real-world problems into the learning process, promoting student participation, collaboration, and critical thinking. The research found that students engaged in PBL showed significant improvements in communication competence, collaboration, and intercultural understanding compared to those in traditional lecture-based instruction. The study suggests that PBL not only enhances language proficiency but also fosters cultural awareness and empathy through projects involving cross-cultural collaboration and problem-solving. Furthermore, PBL offers a more effective platform for practicing language skills in real-world scenarios, as opposed to traditional methods focused on theoretical aspects. The findings demonstrate that PBL is particularly effective in international programs, where students from diverse cultural backgrounds work together to solve global issues, thus improving their ability to communicate and collaborate across cultures. The research concludes that integrating PBL into international language education programs significantly enhances students' cross-cultural communication skills. The study encourages educational institutions to adopt PBL and suggests further research on complementary strategies, including technology, virtual exchanges, and intercultural simulations.

The integration of metaverse technology in employee training has the potential to significantly enhance digital skills, collaboration, and overall learning outcomes in virtual workspaces. This study explores the effectiveness of metaverse-based training compared to traditional methods, focusing on participant engagement, learning retention, and practical application in immersive virtual environments. The results indicate that metaverse technology leads to increased participant engagement, offering real-time communication, interactive simulations, and realistic task scenarios that foster deeper involvement and better skill acquisition. Additionally, the immersive nature of metaverse platforms improves learning effectiveness, especially for high-risk tasks such as medical procedures and technical skills that benefit from hands-on experience. However, challenges such as technological barriers, infrastructure limitations, and initial resistance from employees were identified, requiring organizations to provide adequate support and training for smooth adoption. While the upfront costs of developing and maintaining metaverse training platforms are significant, the long-term benefits—such as scalability, reduced need for physical resources, and enhanced training outcomes—outweigh these initial investments. Organizations looking to implement metaverse-based training solutions should carefully consider the required technological infrastructure, support for employees, and privacy concerns. Future research should explore advancements in metaverse technology, including AI integration, and investigate the broader adoption of these technologies across various industries, focusing on overcoming adoption barriers and measuring their long-term impact on workforce development.

The aim of this research is to classify Indonesia's trade balance data using the SVM (Support Vector Machine) method with two features, namely Gross Regional Domestic Product (X1) and Wholesale Price Index (X2). Classification is carried out by comparing two types of kernels, namely polynomial kernels and RBF (Radial Basis Function) kernels. Equality Hyperplaneobtained from the polynomial kernel is: . The Hyperplane equation obtained from the RBF kernel is:  Experimental results show that classification with polynomial kernels provides better performance than RBF kernels. This can be seen in the evaluation results which show that the Polynomial kernel has an average model goodness of 75.93% and for the RBF kernel the average model goodness is 74.07%. Leave One Out cross validation (LOOCV) simulation for training data obtained an average accuracy of 76.67% for the polynomial kernel and 66.67% for the RBF kernel. This shows that in this classification context, kernel polynomials are more effective in separating data classes.

Fires in residential areas usually occur in densely populated areas. Rawa Buaya Village is a sub-district in West Jakarta City which has a fairly high population density and there is also a densely populated settlement located at RT.016/RW.04 with 445 families. This settlement experienced fire disasters five times in 2008, 2009, 2015, and twice in 2022. The aim of the research is to describe community preparedness to reduce the risk of fire as well as factors that support and inhibit community preparedness. This research uses descriptive methods through a qualitative approach. The results of the research show that 40% of the community knows that the cause of fires is due to human negligence, 81% have the desire to prevent fires, 76% have an agreement between the Head of the RT and the community, 74% have determined the evacuation location for victims, 67% do not know the evacuation route board, 91% have the desire to to help their relatives, 62% only knew that a fire simulation had been carried out once, 74% had no early warning system, and 60% had not prepared an emergency fund. So it was concluded that the community was sufficiently prepared to face fires by knowing the causes and things to prevent fires, having an agreement to prepare evacuation locations, helping relatives and participating in disaster simulations, but the vulnerability of the living environment was a factor that triggered fires.

One important technique for understanding and analyzing computer network performance is TCP/IP simulacrum. In this research, we simulate a TCP/IP network using the bus topology as a model. We use the Cisco Packet Tracer simulated network topology builder to create a bus topology and implement the TCP/IP protocol. The simulation results provide more accurate understanding of how the TCP/IP protocol functions within a bus network. We analyze network performance in terms of throughput, latency, and packet loss. The analysis's findings indicate that bus topologies have a certain amount of leeway in network operations, particularly when a collision occurs. However, this simulation offers a valuable tool to improve computer network design and management.      

Currently, the government is increasingly building PLTMG to fulfill the electricity needs of the society. Beside for fulfill the electricity needs of the Indonesian people, PLTMG also has a negative impact on the society, especially for the community around the PLTMG in the city of Batam. So companies need to conduct studies on environmental impacts, one of which is the impact of the air produced on the surrounding area. The PLTMG industry does not use air pollution control devices, but uses a leanox combustion control system on each gas engine with a chimney outlet that emits SO2 and particulate emissions. The model simulation was carried out using Aermod view software with meteorological data from the affected locations. The results of AERMOD modeling show that the PLTMG industry will have an impact on particulate emissions in the ambient air around the activity location which will spread to the northwest, north, south and east of the activity location. The Aermod Model also shows that current conditions have resulted in dispersion with concentrations below the maximum limit stated in the 2021 Government Regulation. The addition of an emission monitoring system such as CEMS can be used to help monitor the concentration of dispersed emissions. Apart from that, emission control devices such as incinerators or combustion can also be used to reduce the concentration of the emissions used.

This activity discusses the importance of training in implementing data management information systems to increase the efficiency and effectiveness of human resource (HR) management in the context of social welfare. Data management information systems provide a structured framework for managing HR data, enabling organizations to make better and faster decisions. However, the successful implementation of this system depends on HR's understanding and skills regarding its use. Therefore, this activity proposes a comprehensive training program for HR that focuses on the use of data management information systems. Effective training methods include practical learning, case simulations, and interactive sessions to ensure in-depth understanding and practical application of the material studied. Through this approach, it is hoped that organizations can improve the performance of their human resources in managing social welfare data, which will ultimately have a positive impact on operational efficiency and effectiveness as well as the resulting social impact.

The primary problem for multi-robot displacement and motion phase solving requires that the robots prevent themselves from colliding with each other as well as stationary obstacles. In certain situations, robot conflict is unavoidable if one robot views its neighbors as immovable obstacles. Hence, this paper proposes a new NURBs (Non-Uniform Rational B-spline) based algorithm for multi-robot path planning in a crowded environment. First, the proposed technique finds each robot's free, smooth, optimal path while avoiding collision with the existing obstacles. Secondly, the prospect of possible collision between the preplanned trajectories will be computed to allow the robots to navigate in the same workspace and coordinate between them. Then, each robot's time to arrive at potential collision sites is computed based on its speed. As a result, the robots involved in the collision must choose whether to use the robot priority technique to prevent the collision. Simulation results under different scenarios and comparisons with previous works are provided to validate the work. The obtained results prove that the proposed approach is accurate (as the robot's instantaneous speed is taken into consideration), fast (as there is no need to broadcast the robots’ positions), the robots’ paths are optimal and smooth (to avoid jerk movements), and the approach ensures that the robots will not be trapped by local minima problem.
