Customer satisfaction is a crucial indicator in assessing the quality of a company's products, services and overall experience. This research aims to identify the level of customer satisfaction and optimize the available data for effective use in sentiment analysis. In this study, we analyzed 4,353 customer reviews collected over the past year, with 3,481 reviews used as training data and 871 reviews as testing data. The analysis process was conducted using the Cross-Industry Standard Process for Data Mining (CRISP-DM) approach and leveraged the Logistic Regression algorithm to build a predictive model. Model evaluation using the confusion matrix yielded an accuracy of 94.60%, a precision of 94.26%, and a recall of 94.60%. The analysis was conducted using Jupyter Notebook and the Python programming language. The results indicate that sentiment analysis is effective in identifying and predicting customer satisfaction levels, which in turn can help a company’s products improve its service strategies. The optimization of previously underutilized data now provides deeper insights into customer perceptions and expectations, enabling the company to make more targeted decisions and enhance overall customer satisfaction.

Biotechnology has brought extraordinary advances in health, agriculture, and scientific research, but it has also raised complex ethical challenges, especially in human cloning technology. In the context of biotechnology, cloning refers to the creation of a genetic copy of an organism, and although animal cloning has been successfully carried out for research purposes and increasing agricultural yields, human cloning remains a controversial issue. Ethically, human cloning raises a number of questions regarding human rights, identity, and the potential misuse of this technology for unethical purposes, such as genetic programming or the creation of "design babies." This article examines various ethical views regarding the limits of the use of biotechnology, with a focus on human cloning. The research uses qualitative methods through literature study. Despite the efforts of scientists to continue developing human cloning, as Christians we must take a stand on this matter. The Bible teaches that God as the first initiator created humans in the image and likeness of God, in this case creating humans, God's sole right and obligation.

Construction management is vital for coordinating and overseeing projects to ensure alignment with planned objectives. Factors such as time, cost, and quality demand strict control, as discrepancies between initial plans and actual execution can cause significant challenges. In ship construction, delays in material execution and delivery are frequent bottlenecks, leading to schedule disruptions and negatively affecting project outcomes. Addressing these issues requires effective management and robust risk mitigation strategies. This study proposes a web-based ship construction project monitoring system using the Laravel framework and MySQL database. The system is developed using Extreme Programming (XP), an agile methodology that emphasizes iterative improvement, stakeholder collaboration, and adaptability. XP practices, including test-driven development, pair programming, and continuous integration, ensure the system is reliable, adaptive, and responsive to evolving user needs. Frequent stakeholder feedback and incremental development cycles enable the system to tackle dynamic challenges, optimize resource utilization, and ensure timely project delivery. By incorporating XP principles, this study demonstrates the potential of agile methodologies to enhance construction project management. The resulting system provides a flexible and efficient solution for mitigating delays and improving the overall success of ship construction projects.
