Then, in cycle I, all students obtained high learning outcomes and exceeded the minimum completeness criteria. Meanwhile, in cycle II, there were 2 students with moderate learning outcomes who met the minimum completeness criteria, and 14 students with high learning outcomes who exceeded the minimum completeness criteria. The results of this research indicate that the application of the discoverylearning model can improve the mathematics learning outcomes of fraction material for class 2 students at SDN 3 Pancor.

Dampak Perubahan Iklim terhadap Keanekaragaman Hayati dan Kesehatan Lingkungan

2024-10-09T02:12:40+00:00

Climate change is an urgent and complex global challenge that not only affects weather patterns and global temperatures but also has a pervasive impact on biodiversity and environmental health worldwide. Melting of polar ice and rising global sea levels are living examples of widespread observable physical effects. Additionally, these changes also alter rainfall patterns, intensifying droughts in some areas while increasing the risk of floods and storms in other areas. The complex interaction of climate change and biodiversity exacerbate conditions by causing disruptions to the life cycles of species, facilitating the spread of invasive species, and increasing the risk of vector diseases. Effective mitigation strategies are needed to reduce greenhouse gas emissions through renewables, maintain and recover natural ecosystems, and strengthen ecosystem adaptation to minimize these adverse effects. International collaboration and policies supported by scientific evidence are key to meeting this global challenge, with the goal of building a more sustainable future for global environment and health.

Peran Manusia Dalam Mempertahankan Ketersediaan Sumber Daya Alam Melalui Etika Lingkungan

2024-10-09T02:12:36+00:00

The environmental conditions significantly influence human daily life, especially their reliance on natural resources such as land, water, and air. However, environmental degradation in Indonesia is increasing due to a lack of attention to environmental ethics, driven by materialistic views and economic incentives resulting in a global ecological crisis. The environment encompasses everything that affects the survival of humans and other creatures. Environmental ethics are crucial to maintaining the balance of nature. There are three theoretical perspectives on environmental ethics: anthropocentrism, biocentrism, and ecocentrism. The principles of environmental ethics include collective responsibility, care for nature, non-harm to other living beings, simple living, justice in resource management, democracy in environmental policy-making, and moral integrity. Implementing environmental ethics involves a friendly attitude towards the environment in every aspect of life. Human behavior towards the environment should reflect an awareness of collective responsibility for preserving nature, even though technological advancements tend to harm the environment. Concrete actions from all parties are needed to preserve and restore the environment.
