A. PETA KONSEP
B. APERSEPSI
Diskusi Kelas
Pernahkah Anda melihat kapal miring atau hampir terbalik? Mengapa beberapa kapal tetap tegak bahkan dalam kondisi laut yang kasar?
Diskusikan pertanyaan ini secara singkat bersama teman.
C. SHIP ANATOMY (ANATOMI KAPAL)
1. Main Parts of a Fishing Vessel
| Part | Explanation |
|---|---|
| Hull | The main body of the ship that floats on water |
| Deck | The flat surface on top of the hull |
| Bridge | The control room of the ship |
| Keel | The bottom backbone of the ship |
| Cargo Hold | Space for storing fish and equipment |
Contoh Kalimat:
• The hull keeps the ship floating on water.
• The bridge is used to control the ship.
D. BASIC CONCEPT OF SHIP STABILITY
1. Important Terms
| Term | Meaning |
|---|---|
| Buoyancy | The force that pushes the ship upward |
| Gravity | The force that pulls objects downward |
| Center of Gravity (G) | The point where the ship's weight acts |
| Center of Buoyancy (B) | The point where buoyant force acts |
| Equilibrium | A balanced condition |
Key Idea: A ship stays upright when buoyancy and gravity are balanced.
E. HOW A SHIP STAYS UPRIGHT (EXPLANATION TEXT)
A ship stays upright because of buoyancy and gravity. Buoyancy pushes the ship upward, while gravity pulls it downward. When the center of gravity and the center of buoyancy are in line, the ship is stable. However, when cargo is placed too high or unevenly, the ship can tilt and become unstable. As a result, the ship may capsize.
F. CAUSE AND EFFECT LANGUAGE
Common Connectors:
Cause Connectors
• because of
• due to
Effect Connectors
• therefore
• as a result
Contoh:
• The ship tilted because of uneven cargo distribution.
• The center of gravity moved up, therefore the ship became unstable.
G. MARITIME SAFETY CONTEXT
Common Causes of Capsizing:
• Uneven cargo loading
• Overloading
• High center of gravity
• Rough sea conditions
Safety Tips:
- Load cargo evenly
- Follow safety procedures
- Check ship stability before sailing
H. MINI TASK
Tulis 3-4 kalimat menjelaskan mengapa kapal penangkap ikan bisa terbalik menggunakan konektor sebab-akibat (cause-effect connectors).
Contoh jawaban: "A fishing vessel can capsize due to uneven loading of fish in the cargo hold. Because of this uneven distribution, the center of gravity shifts to one side. Therefore, the ship becomes unstable in rough sea conditions. As a result, the vessel may overturn if corrective actions are not taken immediately."
I. REFLECTION
Jawab pertanyaan berikut:
1. Apa bagian terpenting dari stabilitas kapal?
2. Mengapa stabilitas kapal penting bagi nelayan?
J. SUMMARY
- A ship has many important parts with different functions.
- Ship stability depends on buoyancy and gravity.
- Uneven loading can cause capsizing.
- Understanding ship stability helps improve maritime safety.
