This research proposes an alternative model for predicting the plasticity potential of clay soils, updating the previous model developed by Firincioglu and H. Bilsel. The alternative lies in the use of the fine fraction content (FC) as the predictive variable, replacing the percentage of sand fraction content (SC) previously suggested. The analysis was conducted on 61 low-plasticity clay (CL) soil samples, classified using the Casagrande and Moreno-Maroto systems, by examining the relationship between consistency limits (LL, PI), grain fractions (sand, silt, clay), and related parameters (FC, sand-silt-clay spectrum, and sand fraction ratio). The correlation analysis results show significant findings, including a strong positive correlation between sand content and the sand ratio (SR), as well as a negative correlation between sand content and FC, and between FC and SR. The performance of the substitute Casagrande quadratic model [2] reveals the best predictive accuracy among the proposed models ( [1], R² =0.90; [3], R²  0.89; [4], R² =0.43; [5], R² =0.93; [6], R² =0.93; [7], R² =0.89; [8], R² =0.89), with the highest R2 value of 0.93, MSE of ≈4.01, and MAE of ≈1.44–1.47.

This study investigates the influence of discount programs, digital marketing strategies, and service quality on prospective students’ decisions to enroll at STIE Surakarta. The increasingly competitive landscape of private higher education in Indonesia requires institutions to formulate effective marketing strategies that can address the expectations and behavioral tendencies of Generation Z. A quantitative approach was employed using survey data from 36 new students selected through purposive sampling based on their participation in discount-based admission programs. The research instruments were validated through correlation tests and demonstrated reliable internal consistency. Data were analyzed using multiple linear regression to identify both partial and simultaneous effects among the variables. The findings reveal that discount offers are the only variable that significantly affects enrollment decisions, indicating that financial incentives remain a dominant consideration for prospective students evaluating private tertiary education options. Meanwhile, digital marketing and service quality, although yielding positive regression coefficients, do not show significant partial effects. However, the three variables collectively have a significant simultaneous effect, suggesting that enrollment decisions are shaped by a combination of economic, promotional, and perceptual factors. The model explains 45.7% of the variance in enrollment decisions. These results highlight the need for higher education institutions to balance financial incentives with consistent digital marketing execution and improved service delivery. The study contributes to the expanding literature on student decision-making behavior and offers practical insights for strengthening competitive marketing strategies in private higher education.

This study examines the urgency of institutional transparency in the Secretariat of the Bogor Regency Regional People's Representative Council  (DPRD) amid demands for good governance. The objective is to analyze the strategic role of the Public Relations, Protocol, and Publication Team of the Bogor Regency DPRD Secretariat in disseminating public information, with a focus on the use of the @setwankabbogor Instagram account as an instrument of transparency. Using a qualitative approach with a case study design, this research applies qualitative content analysis and observation of Instagram accounts, supported by organizational documentation related to the main tasks of Public Relations. The communication practices found were analyzed based on the theoretical benchmarks of the Two-Way Symmetrical Model and Organizational-Public Dialogic Communication (OPDC). Preliminary research results show that although Public Relations has been effective in documenting protocol and routine administrative activities, content related to core legislative functions such as the budget (KUA/PPAS) and oversight tends to be less dominant than ceremonial posts. The communication model applied still leans toward the Public Information Model, rather than the optimal Two-Way Symmetrical Model. Analysis shows a deficit in dialogic elements, particularly in genuine responsiveness (mutuality) and proactivity in discussing complex public issues, which has the potential to hinder the development of public trust. Optimization requires a shift in strategy towards evidence-based content planning and a focus on proactive dialogue and responsiveness, supported by institutional commitment and increased human resource capacity.

Waste management remains one of the major challenges in urban areas, including Rungkut Menanggal Subdistrict, Surabaya. Although two active waste banks already exist, community participation and the optimization of social and material assets remain limited. This community empowerment program aims to optimize local potential through the strengthening of social and material assets based on waste bank activities using the Asset-Based Community Development (ABCD) approach. This approach emphasizes the utilization of existing community strengths and resources to create sustainable social transformation. The program was carried out through five participatory stages: discover, dream, design, define, and destiny. The results show a significant improvement in the community’s capacity for household waste management. Residents were able to process approximately 100 kg of organic waste into compost and create creative products such as decorative bags made from plastic waste. Moreover, collaboration among local institutions such as Karang Taruna Arkidli, PKK, Posga Venus, Posga Bumi, and KSH increased, strengthening collective action in environmental management. This program demonstrates that the ABCD approach effectively enhances social capital, increases community participation, and generates both economic and environmental benefits. Waste bank management based on local asset empowerment can serve as a model for inclusive and adaptive community development in urban environmental contexts.

This study aims to identidy and examine how people’s views on product quality and brand image affect their decision to buy Shell fuel in Surabaya City. The study fecoses on three key areas: first, how both product quality perception and brand image together influence purchase decisions; second, how product quality perception alone impacts purchase decisions; and third, how brand image alone affects purchase decisions. The group of people studied are those who buy and use Shell fuel in Surabaya. To select participants, a non-probability sampling method was used, with the criteria that respondents must be at least 17 years old, live in Surabaya, and have purchased Shell fuel. After distributing questionnaires, 100 people met these criteria. The data was analyzed using Partial Least Squares-Structural Equation Modelling (PLS-SEM) with SmartPLS 3.0 software. The findings show that both product quality perception and brand image together have a significant effect on purchase decisions. Individually, product quality perception has a positive and significant impact on purchase decisions, and brand image also shows a positive and significant effect. These results suggest that improving product quality and enhancing brand image can help Shell increase consumer purchase decisions in Surabaya.

Objectives: This study aims to analyze the direct and indirect effects of Servant Leadership on lecturers’ Job Performance through the mediating variables of Job Satisfaction, Employee Engagement, and Organizational Citizenship Behavior (Organizational Citizenship Behavior). The study also seeks to identify which mediating variable has the strongest influence in explaining the relationship between leadership and performance among lecturers in private universities. Methodology: This study applies a causal quantitative approach using a survey method with a sample of 155 lecturers from Information Technology study programs at private universities in West Java. Data were collected through questionnaires and analyzed using Structural Equation Modeling–Partial Least Squares (SEM-PLS) to test ten research hypotheses and evaluate the mediating effects among variables. Findings: The results show that Servant Leadership has a positive influence on Job Satisfaction, Employee Engagement, and Organizational Citizenship Behavior, but does not directly affect Job Performance. Among the mediators, only Organizational Citizenship Behavior significantly mediates the relationship between Servant Leadership and Job Performance, indicating that lecturers’ voluntary behavior plays a key role in improving performance. In contrast, Job Satisfaction and Employee Engagement do not act as significant mediators. Conclusion: The findings highlight that leadership effectiveness in higher education depends on fostering Organizational Citizenship Behavior rather than relying solely on satisfaction or engagement. The study introduces the concept of Emphatic Leadership, which emphasizes empathy, accountability, and humility as essential values for leaders in academic environments. This approach offers practical insights for developing participative and humanistic leadership models to enhance lecturers’ academic performance.
