In the current era of globalization and technology, computers, RFID are examples of information technology tools that are indispensable for meeting human needs in almost every aspect of life, including the management of infrastructure and equipment lending.According to direct research at Widya Praja Ungaran Vocational School, there are only two workers who handle facilities and infrastructure. In carrying out their work assignments, they still experience difficulties. Excess workload and the process of borrowing tools that still lacks a sense of responsibility, so that the results of the work are not maximized.The existence of increasingly sophisticated technology, the management of infrastructure and equipment lending can be done with the help of technological tools that will be implemented in this school. This research aims to make it easier to administer, because this school has not yet added a new workforce.This research can be designed with the help of software (Bootstrap, MySql), programming (PHP, Arduino IDE) and equipment (NodeMCU ESP8266, RFID, LCD, I2C, buzzer, power supply, breadboard, jumper cables, resistors, LEDs) to provide data information. more accurate, effective, efficient and provide a good working atmosphere in this school. It is hoped that this research can reduce work overload and create a sense of responsibility in borrowing equipment, using local networks (wifi / handphone) and computers or laptops, with the research method used is research and development (R&D).

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.

The library management information system for SMP Negeri 2 Solear has been successfully implemented. Purpose of creating this information system is to make it easier for members to see the list of available books and borrow books easily, namely online, and to help admin staff in managing book, member and book borrowing data. This information system has two views, namely the user page and the admin page. On the user page, users can register as library members, see available books, and can borrow the books they want. On the admin page, the admin can add, subtract and manage book data, view members' borrowing history, and can see the number of books available. This application was created using PHP and MySQL programming languages, the writing method used was System Development Life Cycle (SDLC), system design used Unified Modeling Language (UML), and system display design used Dia Diagram. It is hoped that with this information system users and admins can access the system anywhere and anytime via the internet. And users don't need to come to the library just to see the availability of the books they want to borrow. Apart from that, admin work can be lighter without taking notes manually.

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.

This study investigates the ethical considerations in cross-cultural communication within student exchange programs, focusing on the application of Neuro-Linguistic Programming (NLP) techniques such as mirroring, rapport building, reframing, and anchoring. These methods were analyzed for their effectiveness in enhancing understanding and reducing miscommunication among students from diverse cultural backgrounds. Data was collected using interviews and questionnaires, revealing that NLP strategies facilitated better adaptation, trust, and collaboration. The Findings highlight that students' responses predominantly fell into positive categories, with Strongly Agree (20.67%) and Agree (79.33%), showing a high level of alignment with the statements presented in the questionnaire. Notably, there were no Neutral (0%), Disagree (0%), or Strongly Disagree (0%) responses recorded, indicating unanimous agreement with the ideas conveyed. These results suggest a strong consensus among students, reflecting their shared perspectives and high levels of agreement on the topics discussed. Importance of ethical communication strategies in fostering meaningful intercultural interactions and mutual respect among participants in a multicultural setting.
