The aim of this research is to evaluate the influence of macroeconomic factors such as interest rates, inflation and exchange rates on the movement of Bank Rakyat Indonesia (BBRI) share prices in the period 2020 to 2024. The analysis used is a quantitative method taking a multiple linear regression approach. The data used is secondary, obtained from other sources, namely the Indonesian Stock Exchange (BEI) and Bank Indonesia (BI). The analysis was carried out using multiple linear regression using EViews 12 software. The findings from the analysis show that the three independent variables do not have a significant impact on BBRI share price fluctuations, both in simultaneous and partial analysis. From the results of the analysis, it can be concluded that there is a relationship where interest rates and exchange rates have a significant positive influence on stock prices, while inflation shows a negative impact on share prices.

Pegadaian is one of the Islamic financial institutions in Indonesia that continues to expand its market share through various marketing strategies. This study aims to analyze the market penetration strategies implemented by Pegadaian and identify the efforts that can be made to increase customer interest. The research method used is descriptive qualitative with a literature study approach from various accredited national journals in the last five years, as well as document analysis related to Pegadaian marketing strategies. The results of this study reveal that Pegadaian market penetration strategy is carried out through the optimization of digital promotion, the development of innovative products and services, and the improvement of financial literacy in society. Digital promotion strategies are carried out by utilizing social media and other online platforms to increase product awareness and education to the general public. In addition, product development such as Arrum Haji and Tabungan Emas has become an effective innovation in meeting market needs. Pegadaian is also actively conducting financial education through seminars, workshops, and outreach programs as a form of improving financial literacy and customer loyalty. These three strategies have consistently proven to attract new customers, increase loyalty, and strengthen Pegadaian position amidst the competition in Islamic financial institutions. This research contributes to enriching the study of marketing strategies for Islamic financial institutions, particularly in the pawnshop sector.

Appropriated artwork refers to the practice of using pre-existing objects or images into new works of art with little or no significant changes to the original form. This trend developed into the Pop Art movement, where one of the characteristic features was the use of images from mass media, as seen in the works of Andy Warhol, including the transformation of Campbell's soup cans into iconic works of art. Although widely appreciated, this work has drawn criticism regarding copyright infringement, raising the question: where do one artist's rights draw on another? To what extent is the appropriation of copyright protected works considered legal without violating the rights of the original creator?
The research results show that the two legal systems differ significantly in the aspects of exclusive rights, moral rights, protected works, exceptions, and duration of protection. The challenge in understanding fair use lies in determining the boundaries between the rights of one artist and another. The fair use doctrine assesses four main factors: the purpose and character of the use, the nature of the original work, the proportion of the work used, and the impact on the market. Courts in the US often favor fair use if elements of transformation are identified, measuring the extent to which the appropriated work carries elements of originality or new creativity. Indonesia could consider adopting the fair use doctrine by adapting the concept through ministerial regulations or other implementing regulations.

The graduate profile of the Chinese Language Education Study Program aims to produce Chinese language teachers who can both teach and conduct research on Chinese language learning issues. Culturally responsive teaching is a method for developing adaptive and responsive educators. Chinese language teachers who are culturally responsive will be able to connect Chinese culture with students' backgrounds and create meaningful learning by utilizing cultural knowledge and students' learning styles. This research aims to analyse the distribution of courses in the Chinese Language Education curriculum in Indonesia that adopt culturally responsive teaching; identify the implementation of culturally responsive teaching for strengthening prospective Chinese language teachers; and explain the factors hindering and supporting the success of culturally responsive teaching for strengthening prospective Chinese teachers. The research method used is qualitative research, utilizing an observational descriptive qualitative approach. The study was conducted to systematically describe the phenomenon of culturally responsive teaching based on factual data. Data collection techniques include literature review, documentation, observation, questionnaires, and interviews. The results of this study show that the Chinese Language Education programs in Indonesia have adopted culturally responsive teaching in their curricula, both in education-focused and non-education-focused programs. This implementation helps prospective teachers understand the relationship between language and culture, although various challenges remain, such as a lack of training, limited resources, negative attitudes, and high workloads. However, success is also evident through teacher commitment and interest, institutional support, integrated curriculum, technology and learning media use, and interdisciplinary approaches. With continuous evaluation and proper support, culturally responsive teaching has the potential to further enhance the competencies of prospective Chinese language teachers in implementing culturally responsive teaching.

The increasing use of mobile devices has increased the risk of data theft, posing significant security challenges for individuals and organizations. This study proposes an early detection system for data theft on mobile devices using machine learning algorithms. The system is designed to identify suspicious patterns in application usage, network access, and CPU/memory activity, providing early warnings to prevent potential data loss. By employing algorithms such as Random Forest, Support Vector Machine (SVM), and Convolutional Neural Network (CNN), the developed models demonstrated significant performance: CNN achieved the highest accuracy of 95.1%, with a precision of 94.2%, recall of 93.5% , F1-score of 93.8%, and AUC-ROC of 0.96. Random Forest and SVM also showed competitive performance with accuracy rates of 94.7% and 92.5%, respectively. These findings highlight the high potential of machine learning algorithms for real-time detection of data theft threats, providing adaptive protection against evolving cyberattack methods. This approach offers a promising solution to strengthen mobile device security frameworks and safeguard user data against increasingly sophisticated cyber threats.
