Activities such as planting, watering, observing insects, and maintaining garden cleanliness provided meaningful and enjoyable learning experiences. In addition, the utilization of vacant land was an effective solution in creating a contextual and child-friendly learning atmosphere. The environment around the school was optimally utilized as a learning medium appropriate to the development of early childhood. This study concluded that the nature center significantly contributed to increasing children's learning activities. Therefore, this nature-based learning model can be recommended as an innovation in early childhood learning for other educational units. 

Carbonate rocks are one of the most important geological resources with a significant role in various industrial sectors, particularly as the main raw material in cement, lime, and construction industries. This study aims to review the characteristics, quality, and industrial potential of three major carbonate rock types—limestone, dolomite, and marble—based on relevant scientific literature. The research employed a literature review method using a qualitative-descriptive approach through analysis and synthesis of previous studies. Data were collected from scientific publications addressing the mineralogical, chemical, and physical aspects of carbonate rocks and their implications for industrial performance. The findings indicate that the quality of carbonate rocks is largely determined by mineral composition (calcite and dolomite), chemical purity (CaO and MgO), and the presence of impurities such as silica, alumina, and iron oxides. High-purity limestone rich in calcite is identified as the most efficient raw material for cement and lime industries due to its stable processing behavior and lower energy requirements. Conversely, dolomite with high magnesium content requires process adjustments to prevent excessive MgO formation during calcination. Marble, both in natural and waste powder form, shows promising potential as a supplementary material in sustainable cement production. Overall, this study emphasizes that understanding the mineralogical and chemical variations of carbonate rocks is essential for optimizing their processing strategies and promoting sustainable industrial utilization

This study aims to analyze the transformation of the educational pattern at the Indonesian Naval Academy (AAL) from a four-year to a three-year system and its impact on graduate competencies and operational readiness. This educational system change responds to budget efficiency needs and accelerated officer formation filling, yet raises questions about the new system's ability to maintain the quality of officer education. The research employs a mixed methods approach with a concurrent embedded design, involving 250 respondents comprising graduates from both educational systems, AAL instructors, and unit commanders receiving graduates. Quantitative data were collected through structured questionnaires and analyzed using descriptive and inferential statistics (independent sample t-test and regression), while qualitative data were obtained through in-depth interviews, observations, and document studies analyzed using thematic analysis. Results indicate no significant difference in overall Grade Point Average (GPA) between the two groups (p=0.470), but significant differences in competency patterns emerged: four-year system graduates excelled in theoretical competencies (p=0.001), while three-year system graduates excelled in practical competencies (p=0.003). Operational readiness evaluation shows that four-year system graduates obtained higher scores (82.5) compared to three-year system graduates (78.3), with significant differences (p=0.012), particularly in strategic leadership and complex decision-making aspects. Qualitative analysis identified five major themes: high learning time pressure, orientation shift from comprehensive to pragmatic, gaps in character formation and corps values, concerns about theoretical understanding depth, and need for more intensive post-graduation mentoring programs. This study concludes that educational time compression successfully increased operational efficiency but involved trade-offs in learning depth and professional maturity. To optimize the three-year educational system, a comprehensive approach is required, including curriculum revision with integrated learning methods, utilization of modern learning technology, strengthening of leadership development programs, and development of continuous professional mentoring systems. The recommendations of this research are expected to provide input for AAL and the Indonesian Navy in refining the officer education system to produce officers who are not only technically competent but also mature in leadership and strong in character.
