Kurikulum Merdeka IPS Kelas 7 Tema 3 Bagian A Perubahan Potensi Sumber Daya Alam

Summary

This video lesson explores the economic potential and environmental resources of Indonesia, focusing on the classification and utilization of natural resources like forests, mining, and marine assets. It covers the various functions of forest areas, the mining process, and the different marine resources available, including fisheries, energy, and tourism. Additionally, it highlights how population growth, over-exploitation, and environmental degradation impact resource sustainability. The lesson emphasizes the need for sustainable practices to preserve these vital resources for future generations.

Takeaways

• 😀 Natural resources are essential for human life and come from the Earth's surface, with two main types: renewable and non-renewable.
• 😀 Indonesia’s natural resources are categorized into three main sectors: forest resources, mining resources, and maritime resources.
• 😀 Forest resources in Indonesia are classified into three types: production forests, conservation forests, and protected forests.
• 😀 Production forests provide raw materials like wood and rattan, while conservation forests focus on preserving biodiversity and ecosystems.
• 😀 Protected forests help prevent erosion, regulate water supply, and mitigate environmental issues like flooding and coastal intrusion.
• 😀 Mining resources in Indonesia are divided into three groups based on their importance and impact on national security and the public's needs.
• 😀 Group A mining resources, such as oil and gas, are managed by the government and have national security significance.
• 😀 Group B mining resources, like gold and silver, are used for public welfare, while Group C mining resources, such as limestone, support industries.
• 😀 The mining process involves several stages: prospection (searching), exploration (evaluating), exploitation (extraction), and processing (refining).
• 😀 Maritime resources in Indonesia include fisheries, marine energy, and marine tourism, all of which are crucial for the economy and biodiversity.
• 😀 Human population growth, excessive exploitation of natural resources, and environmental pollution are primary factors contributing to the degradation of natural resources.

Q & A

What are the two main categories of natural resources?

Natural resources are divided into two main categories: renewable resources (which can be replenished naturally) and non-renewable resources (which cannot be replenished).

What are the three types of forest resources in Indonesia?

The three types of forest resources in Indonesia are: production forests (used for raw materials like wood and rattan), protected forests (which help manage water supply, prevent erosion, and protect against floods), and conservation forests (which include nature reserves and wildlife reserves to protect biodiversity).

What is the difference between a nature reserve and a wildlife reserve?

A nature reserve focuses on preserving specific plant, animal species, and ecosystems, while a wildlife reserve specifically aims to protect the biodiversity and the unique species of animals.

What are the three groups of mining resources in Indonesia, and how are they categorized?

Mining resources in Indonesia are classified into three groups: Group A (materials important for national security, such as oil and gas), Group B (materials for public use, like gold and silver), and Group C (industrial materials, such as sand and limestone).

What stages are involved in the mining process?

The mining process involves four stages: prospection (exploration to find valuable minerals), exploration (determining the size, shape, and quality of the resource), exploitation (the actual extraction of materials), and processing (refining and improving the quality of the extracted materials).

What are the types of maritime resources in Indonesia?

Maritime resources in Indonesia include fishing, marine energy (such as wave, tidal, and thermal energy), and marine tourism (which involves activities like snorkeling and underwater photography).

How does traditional fishing differ from modern fishing methods in Indonesia?

Traditional fishing is typically done by local fishermen using simple equipment, such as sailing boats and basic nets, while modern fishing involves motorized boats and refrigeration to store fish for longer periods.

How does population growth impact natural resources?

Population growth increases the demand for natural resources, leading to over-exploitation. As the population rises, the need for food, water, and raw materials increases, often straining the availability of resources.

What are the negative effects of over-exploitation of natural resources?

Over-exploitation of natural resources can reduce their availability, damage ecosystems, and lead to resource depletion. For example, forests might not regenerate quickly enough, or minerals could be exhausted faster than they can be replenished.

How do pollution and environmental damage affect natural resources?

Pollution and environmental damage, caused by human activities, can destroy habitats, reduce biodiversity, and contaminate air, water, and soil, making natural resources less available and harmful for human use.
