The rapid advancement of digital technology has transformed the landscape of education, particularly in secondary schools. This study investigates the influence of digital learning innovation on enhancing deep learning and student engagement. Using a quantitative survey method, data were collected from 150 secondary school students in Indonesia who actively use digital learning platforms such as Learning Management Systems (LMS), mobile learning applications, and hybrid learning models. The research instrument consisted of a closed-ended questionnaire using a five-point Likert scale, which measured students’ perceptions of digital learning innovation, their engagement levels, and indicators of deep learning. Data were analyzed through simple linear regression using SPSS version 25. The results indicate a strong and significant positive relationship between digital learning innovation and both deep learning and student engagement, with a correlation coefficient (R) of 0.732 and an R² value of 0.536. This finding suggests that digital learning innovation explains 53.6% of the variation in students’ deep learning and engagement levels. Students who frequently use digital learning technologies tend to show higher motivation, independence, critical thinking, and reflective learning behavior. The study concludes that digital learning innovation plays a crucial role in supporting meaningful learning and active participation. It highlights the importance of integrating technology strategically into school-based learning to foster adaptive, collaborative, and lifelong learners in the digital era.

Maritime safety is a crucial aspect of the maritime industry, particularly in Indonesia as an archipelagic country. Although regulations regarding maritime safety are well-established, the frequency of maritime transport accidents in Indonesia remains high (KNKT, 2019–2023). This study aims to analyze and test the partial and simultaneous effects of the Port Authority’s Role (X1), Vessel Seaworthiness (X2), and International Safety Management (ISM) Code (X3) on Maritime Safety (Y) at Ketapang Port. The research method used is explanatory quantitative with multiple linear regression analysis. The sample involved 75 respondents, including ship crew members and Port Authority officers, selected using Simple Random Sampling. The analysis results indicate that the three independent variables have a positive and significant impact on Maritime Safety. The regression model shows an adjusted R Square value of 0.610. Among the three variables, the ISM Code (B = 0.410) is the most dominant factor, followed by the Port Authority’s Role (B = 0.389), and Vessel Seaworthiness (B = 0.186). These findings highlight that structured internal safety management (ISM Code) has the highest leverage, supported by strong regulatory oversight.

Located in Karangjati, Semarang Regency. The rapid development of the culinary industry has led to increasingly fierce competition. Customer satisfaction is crucial for business continuity.

This study aimed to evaluate the forage production characteristics of Japanese papaya (Cnidoscolus aconitifolius) as a potential feed source for ruminant livestock. The research employed a case study approach through direct field observations on four mature Japanese papaya plants naturally grown as living fences in Malang City. Measured variables included the diameter of the main branch, number and length of sub-branches, forage yield, and nutrient composition. Data were analyzed using correlation and simple linear regression to determine the relationship between plant structure and forage productivity. The results indicated that the diameter of the main branch showed a strong positive correlation with the number and length of sub-branches, as well as with forage yield and nutrient content (DM, OM, CP, CF, and EE). Regression analysis confirmed that larger branch diameters were consistently associated with higher forage production and better nutrient values. These findings suggest that the diameter of the main branch can serve as a reliable indicator for estimating the forage yield and nutritional potential of Japanese papaya, providing a practical tool for its use in sustainable ruminant feed management.

Employee performance is a key factor in the operational success of a business, including at Kalenan Cafe & Resto Sawahan Nganjuk, which is growing in the culinary sector. The low performance of some employees is suspected to be influenced by suboptimal leadership styles and a compensation system that is not transparent and fair. This study aims to examine the effect of leadership style on employee performance; the effect of compensation on employee performance; and the simultaneous effect of leadership style and compensation on employee performance. The study employed a quantitative survey approach with 65 employees selected using simple random sampling. Data were collected through questionnaires and documentation related to performance, leadership, and compensation, and analyzed using multiple linear regression. The results indicate that leadership style has a positive and significant effect on employee performance, while compensation has a negative yet significant effect.

This study aims to investigate the impact of Instagram social media use on deviant behavior among students at Campus 3 of Mercu Buana University in Yogyakarta. The phenomenon of increased intensity of social media use among students is the main basis of this study, in which Instagram not only functions as an instrument of communication and self-expression, but also as a medium that has the potential to trigger various forms of deviant behavior, such as cyberbullying, self-image manipulation, and social norm violations. The research method used integrates quantitative methods with descriptive design and simple linear regression analysis. Data was collected through a survey distributed to 100 active student participants, whose sample was determined using a simple random sampling method. Validity and reliability tests showed that all research instruments met the criteria for validity and reliability, as reflected in a Cronbach's Alpha value of 0.946. The relationship between Instagram and deviant behavior among students is represented by the regression equation Y = 2.300X + 0.641. These findings indicate that an increase in the frequency of Instagram use correlates with an increase in the potential for students to adopt deviant behavior. It is hoped that this study can serve as a basis for improving digital literacy and educating students on the ethical use of social media in a university environment.
