This research aims to determine the influence of the Problem Based Learning Model on Students' Critical Thinking Ability on Ecosystem Material for Class X Students of State High School 2 Gowa. This type of research uses a quasi-experimental type of research or also called quasi-experiment with a "random pretest posttest control group" design model. There are two data collection techniques in this research, namely, test and non-test, then the data collected is analyzed using descriptive analysis and inferential test analysis. The research results show that the average critical thinking ability students in the experimental class who were taught using the Problem Based Learning learning model were in the very good category with an average score of 78.52 and students' critical thinking abilities, while in the control class who were taught using the lecture method were adequate with an average score 52.55. Inferential analysis in hypothesis testing shows significant results with a sig value of 0.000 > 0.05 so that there is an influence of the Problem Based Learning learning model on students' critical thinking abilities in ecosystem material. This is also reinforced by the results of observations regarding student activity increasing.

The planting of mangroves in the northern district of Pekalongan is a mitigation effort. Where this area has a lot of coastal and coastal areas. This has caused the region to suffer disasters such as flooding and robbery. The function of the mangrove here as a barrier when the seawater is affected.

Water quality plays an important role in maintaining the balance of aquatic ecosystems, including the abundance and diversity of plankton. This study aims to analyze the effect of various water quality parameters such as temperature, dissolved oxygen (DO), carbon dioxide (CO2) levels, Biochemical Oxygen Demand (BOD), pH, brightness, and turbidity on plankton diversity in Bozem. Data were obtained from eight observation stations with water quality parameter measurements and plankton sampling. The results showed that the water quality in Bozem was not optimal, with low DO values ​​(1.79 mg/L), high water temperatures (average 31.05°C), and low brightness (0.30 m), which contributed to the decline in plankton abundance. A total of 39 plankton genera were identified, with Synedra as the most dominant genus. Poor water quality inhibits plankton growth, which can impact the balance of the food chain in these waters. This study shows the importance of better water quality management to maintain the sustainability of aquatic ecosystems in Bozem. This study also contributes to the understanding of the multifactorial interactions between water quality parameters and plankton.

The diversity of macroalgae species in Indonesia's coastal ecosystems is important to understand and protect. Indonesia has a very long coastline and a variety of ecological conditions, from tropical to subtropical areas. This area provides a habitat that supports the growth of various macroalgae species. The method used is a qualitative research method analyzing the diversity of macroalgae species in Indonesian coastal ecosystems and the level of understanding of high school/MA level plant-like protists. Based on the research results, it can be concluded that the level of understanding of SMA/MA students about plant-like protists is still low. Students have difficulty distinguishing between protists and true plants

The implementation of environmental law influenced the success of the Eco Town program in maintaining the sustainability of river ecosystems by providing a strong foundation for preserving the environment. The implementation of strict regulations related to environmental protection and river management is key in ensuring that development within Eco Town does not damage the river ecosystem. In several case studies such as the Ciliwung River and the Brantas River, the implementation of environmental law has recorded significant improvements in the sustainability of river ecosystems. The main challenges faced in implementing environmental laws to support Eco Town programs are resource limitations, especially in terms of funds, technology, and natural resources. These limitations may hinder the effectiveness of the program and affect the ability to address environmental problems such as industrial or domestic waste management, and maintain ecological balance. To overcome these challenges, concrete measures such as improved accessibility and technology transfer, sustainable management of natural resources, and investment in environmental infrastructure are needed. By ensuring a solid environmental law implementation and paying attention to these limitations, the Eco Town program can run more effectively and efficiently in maintaining the sustainability of the river ecosystem and realizing a vision of sustainable development.

This article discusses the importance of building an e-commerce ecosystem that supports the growth of Micro, Small and Medium Enterprises (MSMEs). In an era of increasingly rapid digitalization, MSMEs need to adopt e-commerce platforms to expand their market reach and increase their competitiveness. However, to achieve sustainable growth, a strong and sustainable e-commerce ecosystem needs to be built. In this article, the author identifies the opportunities that exist in building an e-commerce ecosystem that supports MSMEs. One of the main opportunities is access to a wider global market, which can open the door for MSMEs to sell their products to customers around the world. In addition, e-commerce platforms also provide opportunities for MSMEs to utilize new technologies such as artificial intelligence and data analytics to improve operational efficiency and decision making.    

This study aimed to determine the stand structure and tree canopy cover in forest and parak ecosystems in Lubuk Kilangan District, Padang City. This is a descriptive research with a direct observation throught purposive random sampling method. Data were collected by making six of 20 x 20 m plots in each primary forest and parak ecosystem. Tree diameters ≥10 cm were measured in each plot and canopy cover were collected using the Hemispherical Photography method using a mobile phone front camera equipped with a fish-eye lens. Data were analyzed in terms of stand density, basal area, Stand Basal Area (SBA), and percentage of canopy cover. The average tree density in the primary forest area was 913 individuals/ha, while the tree density in the parak was 467 individuals/ha. The SBA value in the primary forest was higher than in the parak, which was 64.10 m2/ha in the primary forest and 14,72 m2/ha in the parak. The average percentage of canopy cover in both areas shows that the percentage of primary forest canopy cover was greater than that of parak. The average value of the percentage of canopy cover in the forest area was 80.48%, while in the parak area was 71.23%. Correlation between tree density, canopy cover, SBA was only occured in primary forest area where the canopy cover negatively correlated with SBA. This study showed that the primary forest area and parak in Lubuk Kilangan Subdistrict have a good tree density, SBA and tree canopy covers.

The aim of this study was to assess the impact of octopus fishing gear use on coral reef ecosystems in Simeulue District. The research was conducted in May 2024, with research methods combining in-depth interviews and field observations. The results show that the use of unsustainable fishing gear, such as nets, contributes to the destruction of coral reefs, which negatively impacts marine biodiversity. Although fishers recognize the importance of ecosystem sustainability, challenges in adopting environmentally friendly practices still exist, including a lack of law enforcement and education. The conclusion of this study emphasizes the need for collaboration between the government and fishing communities in formulating more effective fisheries resource management policies, as well as the importance of training in sustainable fishing techniques. The study provides recommendations for the implementation of stricter regulations on the use of fishing gear, as well as encouraging active participation of fishers in fisheries resource management.
