This study aims to determine and analyze the effect of the Current Ratio (CR) on Return on Equity (ROE) at PT Kino Indonesia Tbk for the period 2015–2025. This research employs a quantitative approach with an associative research design. The data used are secondary data obtained from the company's annual financial statements. The data analysis techniques include classical assumption tests, simple linear regression analysis, partial t-test, and coefficient of determination (R²). The results show that the Current Ratio has a negative and significant effect on Return on Equity. This is indicated by a regression coefficient value of -0.489 and a significance value of 0.001 (< 0.05). In addition, the coefficient of determination (R Square) is 0.734, which means that 73.4% of the variation in Return on Equity can be explained by the Current Ratio, while the remaining 26.6% is influenced by other factors outside this study. These findings indicate that excessively high liquidity tends to reduce the company’s profitability, suggesting inefficient management of current assets. Therefore, companies need to maintain a balance between liquidity and profitability to improve overall financial performance

This research is motivated by the fluctuation in income of areca nut farmers in Lagan Tengah Village, Geragai District, East Tanjung Jabung Regency, which has decreased in recent years. This condition is suspected to be caused by high production costs and unstable areca nut selling prices at the farm level. Therefore, this study aims to determine the effect of production costs and selling prices on areca nut farmer income in Lagan Tengah Village. This research used a quantitative approach with multiple linear regression analysis. The study population was all 1,105 areca nut farmers in Lagan Tengah Village, while the sample size was 92 people, selected using simple random sampling based on the Slovin formula with a 10% margin of error. Data were collected through questionnaires, interviews, observations, and documentation. Data analysis was performed using the classical assumption test, the t-test (partial), the F-test (simultaneous), and the coefficient of determination (R²) test. The results showed that production costs had a partial and significant negative effect on areca nut farmer income, while selling prices had a positive and significant effect on areca nut farmer income. Simultaneously, both variables—production costs and selling prices—have a significant impact on the income of areca nut farmers in Lagan Tengah Village. The coefficient of determination (R²) indicates that production costs and selling prices are able to explain variations in areca nut farmer income quite strongly. From these results, it can be concluded that improving production cost efficiency and stabilizing areca nut selling prices are important factors in increasing the income of areca nut farmers in Lagan Tengah Village. The local government and related institutions are expected to support farmers through subsidy policies, increased market access, and fostering farm management to optimize and sustain farmer income.

This study aims to analyze the effect of inflation and interest rates on the stock prices of banking companies listed in the IDX80 index on the Indonesia Stock Exchange for the 2019–2024 period. Research data were obtained from official reports of banking company stock prices as well as inflation and interest rate data from Bank Indonesia. The study used a quantitative approach with multiple linear regression methods through the SPSS application, and classical assumption tests were conducted as a requirement for analysis. The study population included all IDX80 banking companies, with a saturated sampling technique resulting in five banks that met the criteria during the study period. The results of the partial test indicate that inflation has a positive and significant effect on stock prices, while interest rates have a negative and significant effect on stock prices. This indicates that stable inflation can still improve the performance of the banking sector, while rising interest rates tend to depress stock prices due to increased borrowing costs and a shift in investment to other instruments. The results of the simultaneous test also show that inflation and interest rates together have a significant effect on the stock prices of IDX80 banking companies. The results show that inflation has a significant positive effect on stock prices with a significance value of 0.034, while interest rates have a significant negative effect with a significance value of 0.018. Simultaneously, inflation and interest rates have a significant effect on stock prices with a calculated F value of 14.549 > Ftable 2.70 and a significance of 0.000 < 0.05.

Studi ini dirancang untuk menginvestigasi pengaruh Suhu Permukaan Laut (SST) dan konsentrasi klorofil-a terhadap variabilitas hasil tangkapan ikan di kawasan Pantai Selatan melalui pendekatan model regresi linear berganda dengan estimasi Ordinary Least Squares (OLS). Pada tahap diagnostik awal, terdeteksi adanya indikasi autokorelasi positif pada residual model (statistik Durbin–Watson = 0,993), suatu kondisi yang berpotensi menginduksi bias pada estimasi standard error sehingga dapat mengkompromikan validitas inferensi statistik. Guna mengantisipasi permasalahan tersebut, dilakukan koreksi menggunakan metode Newey-West Heteroskedasticity and Autocorrelation Consistent (HAC) standard errors yang diimplementasikan melalui komputasi Python. Hasil estimasi pasca-koreksi mengungkapkan bahwa secara simultan, variabel SST dan klorofil-a memberikan pengaruh yang signifikan terhadap keragaman hasil tangkapan ikan, dengan nilai koefisien determinasi (R²) sebesar 23,7%. Berdasarkan uji parsial (uji t terkoreksi), SST menunjukkan pengaruh negatif yang signifikan secara statistik terhadap hasil tangkapan, sementara klorofil-a tidak memperlihatkan pengaruh yang signifikan. Temuan tersebut mengimplikasikan bahwa variabel termal (SST) memiliki kontribusi yang lebih dominan dibandingkan indikator produktivitas primer (klorofil-a) dalam memengaruhi dinamika hasil tangkapan ikan pada wilayah kajian.

The performance of health workers is an important element in ensuring the quality of primary health services. In addition to technical and structural factors, psychological aspects such as job meaningfulness and work engagement are increasingly recognized as playing a role in improving performance. Health workers who interpret their work as something of value tend to show higher work attachment, which ultimately has an impact on performance. This study aims to analyze the effect of job meaningfulness on the performance of health workers through work engagement at the Mokoau Health Center, Kendari City. This study used a quantitative approach with a cross-sectional design. All health workers at the Mokoau Health Center as many as 70 people were involved as respondents through the total sampling technique. Data were collected using a structured questionnaire and analyzed using the Partial Least Squares–Structural Equation Modeling (PLS-SEM) method using SmartPLS version 4.0. The results of the analysis showed that job meaningfulness had a positive and significant effect on work engagement (β = 0.563; p < 0.05). Furthermore, work engagement had a positive and significant effect on the performance of health workers (β = 0.638; p < 0.05). The indirect influence test proved that work engagement significantly mediated the influence between job meaningfulness and performance (β = 0.360; p < 0.05). Job meaningfulness improves the performance of health workers through strengthening work engagement. Therefore, the HR management strategy at the Health Center needs to be directed at strengthening the meaning of work and work attachment to improve performance in a sustainable manner.

The rapid development of information technology has transformed social media into a digital space that plays a crucial role in shaping the mindset, behavior, and lifestyle of young generations. TikTok is one of the most dominant platforms used by Generation Z, particularly students, due to its ability to present algorithm-based content that aligns with user interests. This condition has the potential to cause psychological stress in the form of Fear of Missing Out (FOMO), which reflects social anxiety due to the perception of being late in keeping up with trends, information, or experiences that hold a dominant position in the social landscape. This research initiative aims to examine the influence of TikTok usage on the lifestyle configurations of Generation Z students, with FOMO serving as a determinant that strengthens this relationship. This study is designed within the quantitative tradition with a positivist epistemological orientation. The study population includes 250 students from the Faculty of Computer Science at the National Pasim University in Bandung, with a sample size of 72 respondents derived using Slovin's formula. The analysis results indicate that TikTok usage and the level of FOMO have a positive and significant impact on changes in students' lifestyles. The regression coefficient estimates are in the positive direction, with a significance value exceeding the critical threshold of 0.05, indicating a unidirectional relationship between the variables. The model determination estimate, at around 57.5%, confirms that TikTok and FOMO are able to explain a significant portion of the variation in students' lifestyles, while the remainder is influenced by factors outside the scope of this study. This finding confirms that TikTok functions not only as a medium of entertainment but also as an agent shaping lifestyles influenced by social and psychological pressures. Therefore, strengthening digital literacy is crucial so that students can use social media more rationally and responsibly.

The rapid development of artificial intelligence (AI) has brought significant changes to higher education, particularly in the way students think and learn. AI no longer functions merely as a learning support tool but also influences students’ cognitive processes, including critical thinking, problem-solving abilities, and creativity. This study aims to examine the impact of AI usage on the thinking patterns of university students. The research method employed is a literature review, analyzing various accredited national journals and relevant conference proceedings. The findings indicate that AI offers several positive impacts, such as improving learning efficiency, expanding access to information, and supporting the development of creative ideas. However, excessive reliance on AI may also lead to negative effects, including a decline in critical thinking skills and an increased tendency for students to depend on AI-generated outputs without in-depth analysis. Therefore, the role of educators is crucial in guiding students to use AI wisely and responsibly. AI should be utilized as a supportive tool in the learning process rather than a replacement for human thinking. This study is expected to contribute to the development of effective and ethical strategies for integrating AI in higher education.

This study aims to analyze the effect of work stress and work environment on employee performance with job satisfaction as a mediating variable at PT X. This study uses a quantitative approach with a census method of 198 employees at PT X. Data were collected through an online questionnaire (Google Form) and analyzed using Structural Equation Modeling based on Partial Least Square (SEM-PLS) with the help of SmartPLS 4.0. Based on the results of the analysis that has been done, it was found that work stress has a negative and significant effect on employee performance. Meanwhile, the work environment has a positive and significant effect on employee performance. In addition, work stress has a negative and significant effect on job satisfaction. Then, the work environment has a positive and significant effect on job satisfaction, while job satisfaction has a significant effect on employee performance. In addition, job satisfaction is able to mediate the effect of work stress and work environment on employee performance. This study provides a theoretical contribution to strengthen the understanding of the role of job satisfaction as an important mechanism that connects work stress and work environment with employee performance. Management needs to manage work stress through a balanced workload and system arrangement and create a safe and comfortable work environment to improve employee satisfaction and performance. These findings underscore the importance of job satisfaction as a basis for formulating human resource policies. This study is limited by the number of respondents, which is not fully representative of the entire population due to difficulties in communicating with employees. Furthermore, limited access to the research location, which is located outside of Yogyakarta, resulted in the distribution and collection of questionnaires being conducted only through long-distance communication. Future researchers are advised to add other variables and use research subjects from different industrial sectors to obtain a more comprehensive and comparable understanding.
