The findings indicate the importance of increasing the number of counselling teachers to optimally meet students‘ needs and the need to educate school authorities about the duties and functions of counselling and provide a comprehensive overview of the strategic role of counselling in supporting students’ readiness to face academic and non-academic challenges.

Mining roads are one of the most important facilities that greatly affect the smoothness of production and affect mining costs. Therefore, the construction of mining roads must be carried out carefully to meet technical and work safety standards. Road conditions, distance, road slope and road carrying capacity will greatly affect the production capacity of heavy equipment, especially the production capacity of transport equipment. The location of this research is at PT. Energi Cahaya Industritama, precisely in Palaran sub-district, Samarinda city, East Kalimantan province. After observations were made at the research location, it was found that the geometric conditions of the road did not comply with the standards based on the overburden transport equipment or the largest transport equipment, for example, the width of the road on bends and the slope of the road. After conducting the research, the results of the data from the geometry of the access road were obtained, namely, the actual condition of the geometry of the access road on the straight road width is divided into 6 segments with a width of 13.3 meters, 14.3 meters, 14.5 meters, 13.2 meters, 15 meters, 15.7 meters. Meanwhile, the width of the bend road is also divided into 2 segments with a width of 15.9 meters and 15.5 meters respectively. And on the slope of the road there are 2 segments with values ??of 11.1% and 14.8% respectively. Based on the results of the simulation software, the productivity of the transport equipment was obtained at 92.42 BCM/hour, which shows that productivity has increased by 12.23 BCM/hour from the actual productivity value of 80.109 BCM/hour. It has an average cycle time of 10.33 minutes, which shows a reduction in time or 6.01 minutes faster than the actual average cycle time of 16.34 minutes.

This study aims to compare the performance of PT Metro Healthcare Indonesia, PT Kalbe Farma Tbk, PT Indocement Tunggal Prakarsa Tbk, PT Siloam International Hospitals Tbk, and PT Hetzer Medical Indonesia Tbk. The focus of the research is the analysis of financial and operational performance to provide an in-depth understanding of the companies' competitiveness and efficiency within their respective sectors. The study employs a quantitative method with a descriptive-comparative approach. Secondary data were collected from the annual financial reports of each company over a specific period. The analysis was conducted using key financial ratios such as Return on Equity (ROE), Debt to Equity Ratio (DER), and Current Ratio (CR). Additionally, an operational performance trend analysis was performed to understand the comparative effectiveness of the companies in resource management. The results of the analysis indicate significant differences in financial performance between companies operating in the healthcare sector (PT Metro Healthcare Indonesia, PT Kalbe Farma Tbk, PT Siloam International Hospitals Tbk, and PT Hetzer Medical Indonesia Tbk) and those in the building materials sector (PT Indocement Tunggal Prakarsa Tbk). Companies in the healthcare sector tend to have higher profitability ratios compared to those in the building materials sector, although there are variations in debt and asset management efficiency. These performance differences can be attributed to underlying industry factors such as market demand, levels of innovation, and government policies. Companies in the healthcare sector benefit from growth driven by increasing public demand for healthcare services. In contrast, the building materials sector is more vulnerable to economic fluctuations and infrastructure investments. This study concludes that industry sectors and business models have a significant impact on companies' financial performance. Healthcare sector companies demonstrate more stable and promising performance compared to the building materials sector. This study is expected to provide insights for investors in selecting suitable investment portfolios.

The relationship between Islam and democracy has been a complex and often debated topic, particularly in Muslim-majority countries. This research aims to explore the compatibility between Islamic principles and democratic values using Indonesia as a case study. As one of the largest Muslim countries in the world, Indonesia offers a unique context in integrating religious teachings with the modern democratic system. Through qualitative methods that included a Google Form-based survey and a literature review of academic articles and journals, this research found that the majority of respondents (70%) believe that democratic values are in line with Islamic teachings, such as justice, deliberation and equality. However, the research also identified a number of challenges that Indonesia faces in harmonizing the two concepts. The main challenges include differences in the interpretation of Islamic law, difficulties in balancing sharia law with secular law, and the issue of political pluralism. In addition, factors such as intolerance, radicalism and identity politics often become obstacles in creating harmony between religious and democratic values. Despite these obstacles, Indonesia has made significant progress through moderation, strengthening civil society, and successfully managing religious and cultural diversity. Local traditions such as deliberation, gotong royong and pluralism provide a strong foundation for building an inclusive democratic system. This approach is not only relevant for the Indonesian context, but can also serve as a model for other Muslim-majority countries seeking to integrate religion and democracy. This research offers a new contribution to the understanding of the dynamics of the relationship between Islam and democracy, and highlights the importance of civil society strengthening, pluralism education, and the adaptation of religious values in the context of modern democracy. With the results obtained, this research is expected to be a reference for other Muslim countries in creating harmonious and sustainable political governance.

Hydroponic plant cultivation is booming, but stock and sales are hard to predict. Poor prediction can cause farmers to overstock and lose money. This study suggests a framework that uses several machine learning models, including Linear Regression (LR), Random Forest (RF), Decision Tree (DT), and Extreme Gradient Boosting. "Ensemble Learning," which combines these models, should yield more accurate and generalizable results than a single model. This framework is assessed using historical hydroponic plant sales data and related factors like price, weather, and market trends. The model's performance is measured by the difference between predictions and actual values using RMSE and MAE metrics. This framework should improve hydroponic plant stock and sales predictions. Farmers can make better production, inventory, and harvest distribution decisions. Besides reducing financial losses, this reduces food waste and improves food security.
