This study aims to examine the effect of liquidity, profitability, leverage, and accounts receivable turnover on financial distress. The sample used in this study is banking companies listed on the Indonesia Stock Exchange (IDX) for the 2021-2024 period. The population sample in this study is 47 companies. The sample was determined using a purposive sampling method, resulting in 10 companies. The type of data for this study is secondary data obtained from www.idx.co.id. The analytical method used was multiple regression analysis. The results of this study indicate that simultaneously, the variables liquidity, profitability, leverage, and accounts receivable turnover significantly influence financial distress. Partially, the liquidity variable has a negative and significant effect on financial distress, while the profitability variable has a negative and significant effect on financial distress. Leverage and accounts receivable turnover have no effect on financial distress. Furthermore, the Adjusted R-square coefficient is 95.3%, indicating that 4.7% is influenced by other variables. These findings suggest that companies with better liquidity and profitability levels have a lower probability of experiencing financial distress. This aligns with the theory that high liquidity ensures the availability of cash to meet short-term obligations, while strong profitability supports operational sustainability and investor confidence. On the other hand, leverage and accounts receivable turnover did not significantly affect financial distress, which may indicate that banking companies have a more stable debt structure and effective credit management, reducing their influence on distress conditions. This research provides practical insights for company management, investors, and regulators. For managers, maintaining optimal liquidity and profitability levels is essential to prevent financial difficulties. For investors, liquidity and profitability indicators can serve as reliable references for investment decision-making.

The digital competency gap between vocational school graduates and the rapidly evolving demands of modern industry has become a pressing issue in today’s workforce. One of the main challenges lies in the limited digital literacy and insufficient practical skills of students, particularly in applying Artificial Intelligence (AI) tools to support productivity and creativity. This situation hinders the readiness of graduates to compete in an AI-driven labor market, where innovation and technological adaptability are essential. To address this challenge, a training program was designed for vocational high school students at Darma Siswa Sidoarjo with the primary objective of enhancing both their conceptual understanding and practical competencies in the utilization of AI technologies. The program adopted the Participatory Action Research (PAR) method, emphasizing collaboration and active engagement between trainers and students. It was conducted through a series of interactive workshops that combined theoretical introductions with hands-on practice. Students were guided to explore AI-based platforms such as Ideogram for visual creativity, PixVerse for multimedia production, and Suno for AI-generated music. To evaluate the effectiveness of the program, pre-test and post-test instruments were used, focusing on the dimensions of knowledge, technical skills, and student confidence in using AI tools. The findings revealed that students initially demonstrated minimal awareness and limited practical ability in AI applications, as reflected in the pre-test results. However, post-test data showed a significant improvement not only in their technical proficiency but also in their enthusiasm to further explore AI technologies. Moreover, students gained increased confidence in producing creative outputs, transforming their role from passive consumers of digital tools into active and competent content creators. In conclusion, this participatory and practice-oriented training model effectively bridges the digital competency gap, enhances students’ job readiness, and fosters an innovative mindset.

The research that has been conducted is entitled "The Effect of Role Playing Method on Speaking Skills in Drama Texts in Grade VII Students of SMP Negeri 20 Medan" which is motivated by the low learning outcomes in the Indonesian Language subject, especially in language skills. Students show a lack of self-confidence and doubt in conveying ideas or ideas that they have. The research method uses a quantitative method with a quasi-experimental approach, a non-equivalent control group design using a nonprobability sampling technique (purposive sampling) and in the form of a pre-test and post-test with a sample size of 32 students VII-1 and 32 students VII-3. Data collection techniques with observation, multiple choice tests, questionnaires, and documentation. Based on the results of the pre-test that has been carried out, it is known that the average pre-test results of the control class and the experimental class are not much different, namely the average pre-test score of the control class is 56.41 while the experimental class is 57.34. After both classes carried out the learning process with different processes, there was a significant difference in the post-test given, namely the control class obtained a score of 84.22 while the experimental class obtained a score of 89.69. Based on the dialtals, it was proven that there was an increase in learning outcomes after the learning process was carried out.

This program is present as a forum for students to not only understand entrepreneurship theory, but also to practice in real life the process of building and managing a business. In its implementation, the program involves active collaboration between universities, industry mentors, and field supervisors who play a role in providing direction, guidance, and evaluation of student business development. Through Independent Entrepreneurship, students are given the opportunity to design creative business ideas, run a business on a real scale, and solve various entrepreneurial challenges they face. This activity not only trains managerial, communication, and innovation skills, but also improves critical thinking and problem-solving skills. In addition, students gain valuable experience in terms of teamwork, financial management, marketing strategies, building business networks, and the use of digital technology to support business sustainability. The results of the program implementation show positive impacts, including increased confidence, independence, and students' understanding of the real business world. Furthermore, this program encourages the creation of an entrepreneurial ecosystem in a sustainable campus environment and is able to be the forerunner of the birth of a young generation of Indonesian entrepreneurs who are resilient, innovative, creative, adaptive to changing times, and have high competitiveness. Thus, Independent Entrepreneurship not only plays a role as a skill development program, but also becomes one of the important foundations in preparing students to face the world of work and becoming independent business actors who are professional, visionary, sustainability-oriented, and make a real contribution to the nation's economic development.

In addition to the key findings, the study also emphasizes the importance of fostering a deeper understanding of the role of audit committees within the broader context of financial governance. Despite the recognition of the audit committee’s importance in improving the quality of financial reporting, the findings indicate that there is a significant gap in the implementation of best practices across private commercial banks in Iraq. This gap is attributed to the lack of full compliance with regulatory requirements regarding the composition of audit committees, particularly in terms of ensuring independence and financial expertise. The study further reveals that while the audit committee's independence and expertise play a crucial role in enhancing the quality and relevance of financial information, many banks still struggle to implement effective oversight mechanisms. This situation is exacerbated by the complex regulatory environment in Iraq, where overlapping supervisory authorities and weak enforcement of governance mechanisms hinder the effectiveness of financial reporting processes. The lack of coordination between audit committees and internal audit units, as well as the limited ability to assess financial performance, further undermines the oversight function of audit committees. To address these challenges, the study suggests several recommendations, including enhancing the legal framework to enforce stricter compliance with the formation of qualified and independent audit committees. Additionally, increasing awareness and training among stakeholders about the importance of audit committees and their roles in ensuring transparent and reliable financial disclosures is crucial. Strengthening the oversight function and improving coordination between audit committees and internal audit units will also help in mitigating the existing weaknesses in the financial reporting process. These steps are essential for improving the reliability of financial information, thereby fostering investor confidence and contributing to the overall stability of the banking sector in Iraq.

This study investigates KIDI IoT, an educational service by PT Telkom Indonesia designed to bridge the skills gap between Vocational High School (SMK) graduates and the demands of the Industry 4.0 workforce. The primary objective was to assess the extent to which the KIDI IoT service fulfilled the requirements of educators and learners to substantiate its value proposition. A qualitative, exploratory methodology was employed utilizing in-depth interviews and the Value Proposition Canvas (VPC) framework for analysis. The outcomes demonstrate how effectively the program's project-based, experiential approach increases user motivation and offers a practical, industry-relevant learning environment. The service successfully generates the desired customer benefits. A major customer pain point that the current model ignores is that participants often expressed that the two-day offline training period was insufficient to help them master the material or build their confidence for working independently. This led to a significant misalignment. The KIDI IoT value proposition is fundamentally strong and well-regarded; however, the study concludes that its implementation necessitates improvement, particularly through the provision of more specialized teacher training and an extended training duration, to ensure sustained impact and skill acquisition.

Bulian coconut chips are a typical Jambi food made from dried and fried old coconuts. The traditional production method and inadequate hygiene standards make this product susceptible to microbial contamination, especially harmful bacteria. This study aims to identify the types of bacteria that may be present in Bulian coconut chips using culture and Gram staining methods as the initial step for morphological identification. Samples were taken from three local producers in Bulian District, Batanghari Regency, Jambi. Testing was carried out by serial dilutions up to 10⁻⁴, then planted on Nutrient Agar (NA) media and incubated for 24 hours at 37°C. The colonies that grew were then observed morphologically and Gram staining was performed using a modified method without alcohol. The results showed the presence of various colonies with cream, white, and pale yellow colors. Based on the results of Gram staining, bacilli and cocci were found, which were included in the Gram-positive and Gram-negative categories. The types of bacteria suspected to appear include Bacillus sp., Staphylococcus sp., and possibly Escherichia coli. These findings indicate a risk of microbial contamination that could endanger consumer health, especially if the production process is not improved. Strict hygiene and sanitation principles are strongly recommended in the processing of this traditional food to ensure the product remains safe for consumption. The importance of implementing hygienic standards in the production of Bulian coconut chips is further emphasized by these findings. In addition to improving food safety, implementing proper sanitation procedures can also extend the product's shelf life and increase consumer confidence in local traditional foods. Efforts such as training local producers, using clean equipment, and hygienic packaging can help minimize the risk of bacterial contamination.

Understanding verb-noun collocations is essential for exploring how abstract personal qualities are represented in language. This study aims to find out the types of verbs that occur before the five self-related compound nouns (self-esteem, self-confidence, self-assurance, self-worth, and self-respect), and investigate their collocational patterns. The data in this study were obtained from the Corpus of Contemporary American English (COCA). The data were collected by applying the documentation method. The technique involved searching for five compound nouns within the corpus and recording instances of their use. These occurrences, along with their collocates, were then copied and organized in an Excel spreadsheet. In the spreadsheet, columns were adjusted to separate and classify key elements such as the compound noun, the collocating verb, frequency data, and context sentences. The collected data were analyzed qualitatively to provide insights into lexical patterns, the types and tokens of frequency. The results show that the verbs that collocate with five self-related compounds in COCA vary in number and frequency, with self-confidence showing the highest types (20) and self-assurance the lowest (9). The verb build appears most frequently with self-confidence and self-esteem (4 tokens each), suggesting both are viewed as qualities that can be constructed or improved. Self-respect predominantly collocates with have (4 tokens), implying it is seen as possessive, while self-worth reflects both positive and negative framing through increase and reduce (2 tokens each). In contrast, self-assurance is frequently associated with lack (4 tokens) and show (2 tokens), indicating its absence or visibility. These patterns reveal that verb collocates offer important insights into how language frames self-constructions.

The research results show that the Mustahik Mandiri program has had a positive impact, increasing the income, skills, and self-confidence of beneficiaries. Furthermore, the program has contributed to the formation of stronger social networks and the capacity of community-based small businesses. These findings confirm that the Mustahik Mandiri program can be a model for sustainable economic empowerment, with significant implications for improving community welfare and strengthening the role of zakat in national development.

The manual, paper-based election of the Student Council President faces various challenges, such as the lengthy vote counting process and the potential for errors in the recapitulation. To address these issues, this study designed a web-based e-voting information system at SMK Negeri 4 Tangerang Regency. This system was built using the Rapid Application Development (RAD) method, which emphasizes speed of development through iteration and prototyping based on user feedback. The development results indicate that e-voting can accelerate voting and vote counting, provide real-time results, and reduce paper usage. This system has been tested using blackbox testing, proving that all functions work as expected and are easily accessible to students. The study concludes that the implementation of web-based e-voting can improve efficiency, security, and transparency in the election of the Student Council President, with suggestions for system usage simulations and regular usability evaluations. Furthermore, this study also shows that the implementation of a web-based e-voting system can reduce the potential for fraud that often occurs in manual elections. With an automated and integrated system, every vote cast by voters is recorded accurately, reducing human error in the vote counting process. System security is also maintained through authentication mechanisms that ensure only authorized users can vote, as well as data encryption to protect sensitive information. This increases voter confidence in the election results, as the process is more transparent and free from manipulation. Furthermore, although the e-voting system has proven effective in increasing election efficiency and accuracy, the study also recommends the need for training for system users, both students and election committee members, to ensure they can utilize the system optimally. Continuous evaluation of the system's usability is also crucial to ensure that the interface remains user-friendly and easily accessible to all parties.

In helping to support the appearance and confidence of the skin needs to be treated especially for dry skin. Having a dry facial skin causes discomfort because the cosmetics used will be difficult to stick to the skin. In addition, weather factors, the use of unsuitable cosmetics, exposed to excessive sun exposure, and unhealthy lifestyles can cause the skin to become dry. The purpose of this study was to determine the process of making gel masks from carrot extracts and seen from laboratory tests, organoleptic tests and hedonic tests. This study uses quantitative methods with an experimental approach. Data collection techniques through observation, documentation and observation sheets that can be seen from the results of laboratory tests, organoleptic tests (texture, color, aroma, adhesion) and hedonic tests (panelists). The results of the study obtained from the results of laboratory tests by looking at the pH level of each formulation are in a safe range of 4-5. In the organoleptic test, panelists declared F1 as a preparation of less thick, orange, and lack of scented in carrot. In the F2 formulation, panelists declare as a texture preparation that is thick, orange, and scented typical of carrots. In the F3 formulation, the panelists declare that the preparation is less thick, less orange, and a typical carrot scented. In the F4 formulation, panelists declare as a very thick, non -orange preparation. And very scented typical of carrots. In the adhesion of the panelist states from all formulations that F4 is very attached. In the hedonic test, the preparation that many panelists like, namely the F4 preparation, is very thick, not orange and very scented typical of carrots. Thus the gel mask of carrot extract can be used as material for making gel masks seen from laboratory tests, organoleptic tests, and hedonic tests.

The low reading interest and literacy skills of elementary school children in Indonesia remain a problem that requires creative and sustainable solutions. Factors such as limited access to quality books, a lack of reading habits at home, and uninteresting learning approaches are often the causes of a weak literacy culture among students. To address this problem, the Student Community Service Program (KKN) of Sebelas Maret University students in Singodutan Village implemented an activity aimed at fostering a culture of literacy in children through a Reading Book Content-Based Project at SDN 3 Krisak. The concept of this activity integrates reading activities with the creation of creative projects that are appropriate to the content of the reading, so that students not only understand the text but are also able to process the information into real products. This study used a qualitative approach with a phenomenological research type to understand students' experiences during the activity. Data were collected through observation, documentation, and literature review, which were then analyzed descriptively. Activities included selecting reading books appropriate to students' ability levels, shared reading, discussions about the reading content, and the creation of creative projects such as posters, picture stories, or artwork inspired by the reading material. The results of the activity showed an increase in student participation in reading activities, an increase in interest in books, and an improvement in their ability to process information into creative works. Furthermore, students demonstrated greater self-confidence when presenting their work to their classmates.

The purpose of this study is to identify the variables that affect profit growth.  Profit growth is the study's dependent variable, and premium income, claim payments, risk-based capital, and investment returns are its independent variables.  Information was gathered from insurance firms that were listed between 2019 and 2023 on the Indonesia Stock Exchange.  Ten businesses that satisfied specific requirements made up the study's sample.  To get a complete picture of the link between one variable and another, multiple linear regression analysis was employed as the study approach, with a 5% confidence level.  The factors Premium Income, Claim Payments, Risk-Based Capital, and Investment Returns all had a somewhat significant impact on Profit Growth, according to the partial test results. The factors Premium Income, Claim Payments, Risk-Based Capital, and Investment Returns all had a substantial impact on Profit Growth at the same time, according to the results of the simultaneous test.  It is anticipated that other businesses listed on the BEI will use the study's findings as a guide to focus more on financial ratios in order to boost their profits.

This study aims to improve elementary school students' storytelling skills through the application of the Whole Language approach combined with ebook-based image media. The Whole Language approach was chosen because it emphasizes the integration of natural language skills in meaningful contexts, while the ebook-based image media was used to provide engaging visual stimuli, facilitate comprehension of the story, and motivate students in the learning process. The study was conducted at Pekuncen Elementary School in Pasuruan City, with 18 fifth-grade students as subjects. The method used was Classroom Action Research (CAR), implemented in two cycles, each consisting of planning, implementation, observation, and reflection. Data were collected through observation, storytelling skills tests, student interviews, and documentation of the learning process. The results showed a significant improvement in students' storytelling skills. Learning completion increased from 44.44% in the pre-cycle to 66.67% in the first cycle, and reached 88.88% in the second cycle. This improvement included aspects of speaking fluency, the use of a more varied vocabulary, coherent story structure, and the ability to convey appropriate expression and intonation. Furthermore, this approach encourages students to participate more actively in learning, increases self-confidence, and fosters courage in expressing opinions in class. These findings indicate that implementing Whole Language with the aid of illustrated ebooks is effective in developing elementary school students' storytelling skills. The combination of communicative learning methods and engaging media can create a fun, interactive, and meaningful learning environment. This study recommends that Indonesian language teachers at the elementary school level consider using a similar approach as an alternative strategy for teaching speaking skills, particularly in the context of storytelling.

This study aims to determine the relationship between social stigma and psychological well-being in mothers of children with disabilities in Padang City. The background of this study is based on the negative labeling and discrimination often experienced by these mothers, which can affect their mental health and parenting skills in raising children with special needs. The social stigma attached to families with children with disabilities often makes mothers feel protected, experience emotional stress, and decrease self-confidence. This condition has the potential to cause prolonged stress that ultimately has a negative impact on their psychological well-being. This study used a quantitative method with a purposive sampling technique, where 93 respondents mothers of children with disabilities in Padang City were selected as research participants. Data collection was carried out using an instrument in the form of a Likert scale that has been tested for validity and reliability. This scale measures two main variables: the level of social stigma experienced by mothers and the level of psychological well-being, which includes aspects such as happiness, life satisfaction, and overall mental health. The results showed that 30.1% of these mothers reported a high level of psychological well-being, while 34.4% reported a low level of social stigma. These findings indicate relatively good psychological well-being, although some mothers still experience social stigma. Statistical analysis using correlation revealed a significant negative relationship between social stigma and psychological well-being. This means that the lower the level of social stigma experienced by mothers, the higher their level of psychological well-being. These findings confirm that reducing social stigma and discrimination against mothers with children with disabilities is crucial for improving their quality of life.

Mandarin Chinese teaching by non-native teachers is crucial in global education, given the complexity of the language and culture that require in-depth mastery. This study examines the roles, characteristics, challenges, and effective teaching strategies implemented by non-native Mandarin Chinese teachers. Using a qualitative approach and descriptive-analytical literature review, this study collected data from accredited journals and books from online databases such as Google Scholar, ResearchGate, and national journal portals.

The role of non-native teachers is crucial and integral, encompassing motivator, facilitator, role model, learning designer, and evaluator. Non-native teachers also face challenges such as pronunciation and writing difficulties, limited media resources, lack of confidence, and cultural differences. Solutions include the use of digital media, interactive learning strategies, and professional training. Overall, non-native teachers play a fundamental role in Mandarin Chinese language teaching and have the potential for success. With a strong foundation of materials, innovative strategies, adequate training support, and high self-confidence, they can enhance student interest and understanding, although challenges must be addressed strategically.  

This research seeks to examine the impact of inflation and exchange rates on the Jakarta Composite Index (JCI) on the Indonesia Stock Exchange (IDX) from 2019 to 2024. The study uses secondary monthly data for inflation, exchange rates, and the JCI, which were sourced from the official websites of Bank Indonesia and IDX. A quantitative approach is employed, utilizing multiple linear regression analysis along with classical assumption tests and both simultaneous and partial hypothesis testing. The findings reveal that, individually, both inflation and exchange rates have a significant effect on the JCI. When analyzed together, inflation and exchange rates also significantly influence the JCI. These results underscore the importance of macroeconomic stability, particularly the stability of the rupiah exchange rate, in shaping stock market trends in Indonesia. The study suggests that fluctuations in the inflation rate and the exchange rate can lead to uncertainty in the stock market, impacting investor decisions and market performance. These findings are particularly relevant in the context of Indonesia’s open economy, where external factors and global economic conditions can also influence domestic financial markets. This research aims to offer valuable insights to investors, policymakers, and academics, helping them understand how key macroeconomic variables, such as inflation and exchange rates, influence the dynamics of the capital market. The study emphasizes the need for maintaining economic stability to foster a conducive environment for market growth and investor confidence. By analyzing these macroeconomic factors, the study provides a clearer understanding of their role in stock market performance and offers a foundation for future research and policy development in the Indonesian financial market. Additionally, the results of this research could serve as a basis for further studies that explore the relationship between macroeconomic factors and stock market behavior in emerging markets.

Free trade provides significant opportunities for developing countries to increase exports, expand market access, and drive economic growth. Through engagement in global markets, products and services can reach a wider range of consumers, creating the potential for increased national income. However, global economic integration also presents serious challenges, particularly in terms of the protection of Intellectual Property Rights (IPR). As national boundaries in economic activity become increasingly blurred, intellectual property—including patents, trademarks, industrial designs, copyrights, and trade secrets—becomes increasingly vulnerable to infringement. Common forms of infringement include piracy, counterfeiting of branded products, and theft of technology or innovation. These practices not only harm creators or rights owners but can also hinder the development of innovation, reduce industrial competitiveness, and undermine consumer confidence. Adequate IPR protection requires a combination of strong national regulations and an effective international legal framework. Instruments such as the TRIPS (Trade-Related Aspects of Intellectual Property Rights) Agreement under the WTO provide global standards to which compliance must be adhered, but implementation at the national level is crucial for their success. Weak or inconsistent law enforcement can open the door to violations that harm both domestic and foreign businesses. Beyond legal aspects, effective IPR protection also impacts the investment climate. Investors tend to invest in countries that can guarantee the security of their intellectual assets. Therefore, IPR protection is not only a legal issue but also a long-term economic development strategy. Therefore, in the era of free trade, developing countries need to balance market openness with strengthening IPR protection systems to create a conducive environment for innovation, sustainable economic growth, and public welfare.

This study aims to: (1) produce e-LKPD based on problem-based learning oriented to mathematical problem-solving ability and self-confidence of high school students on the material of equations and quadratic functions and (2) describe the feasibility of PBL-based e-LKPD oriented to mathematical problem- solving ability and self-confidence of high school students on the material of equations and quadratic functions seen from the aspects of validity,  practicality, and effectiveness. This type of research is research and development using the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). The research was conducted at SMA Negeri 1 Malinau with the research subject of class X-3 students totaling 35 students. Data collection was carried out using interview techniques, observation, e-LKPD validation sheets, pretest-posttest, and questionnaires. To determine the validity, the e-LKPD assessment sheet of material and media experts was used, practicality used student and teacher response questionnaires, and effectiveness used mathematics problem solving ability test questions and student self-confidence questionnaires. Data analysis consisted of qualitative data analysis and quantitative data analysis. Qualitative data analysis was conducted by analyzing the results of interviews, observations, and comments or suggestions given to make improvements to the e-LKPD products developed. Quantitative data analysis was conducted by converting quantitative data into qualitative data in the form of certain categories, normality test using shapiro-wilk, t-test with paired samples test, and N-Gain score. The results showed: (1) PBL-based e-LKPDs oriented towards mathematical problem solving skills and self-confidence of high school students on the material of quadratic equations and functions have been produced, (2) PBL-based e-LKPDs developed meet product feasibility, namely valid with excellent categories based on material and media experts; practical with very practical categories based on teacher responses and practical based on student responses; effective on math problem solving skills with classical completeness of 77%, the t-test results obtained a significance value of 0.000 <0.05 which means that there is a difference in the average ability to solve mathematical problems before and after learning using e-LKPD, the N-Gain result is 0.65 with moderate criteria, and effective on student self-confidence with an increase in the average score of each indicator before and after learning,  the N-Gain result is 0.49 with moderate criteria, and the t-test results with a significance value of 0.000 < 0.05.
