LKPD Pertemuan 3 – JCOT

📘 Bahasa Inggris / Kelas XI / Semester Genap
🐟 Nursery Management (Pendederan Payau & Laut) | CEFR A2–B1

✅ Tujuan: Membandingkan teknik 💬 Berpendapat & merespon

📖 B. Aktivitas 1 – Case Study Reading

Bacaan singkat: Milkfish nursery uses brackish water (salinitas 15–25 ppt). Grouper nursery uses marine water (28–32 ppt). Brackish ponds dekat mangrove, marine tanks butuh air laut bersih. In contrast, air payau punya oksigen lebih rendah tapi pakan alami lebih banyak. However, marine water butuh peralatan mahal.

🎯 LEVEL A2 – 3 kalimat sederhana

Tugas: Tulis 3 perbedaan dalam 3 kalimat sederhana.

✅ Contoh jawaban:
1. Milkfish uses brackish water, but grouper uses marine water.
2. Brackish ponds have mangroves, but marine tanks need open sea water.
3. Marine equipment is more expensive than brackish equipment.

🌟 LEVEL B1 – 5–6 kalimat (cohesive devices)

Tugas: Gunakan in contrast, however.

✅ Contoh jawaban:
Milkfish nursery uses brackish water (15–25 ppt). In contrast, grouper nursery requires marine water (28–32 ppt). Brackish ponds are near mangroves. However, marine tanks need clean seawater. Moreover, marine systems are more expensive. Therefore, each method has different costs.

🎙️ C. Aktivitas 2 – Panel Discussion

Peran: 🐟 Pakar Bandeng (Milkfish) | 🐠 Pakar Kerapu (Grouper)

Moderator: “Which method is better for beginner farmers?”

🎙️ A2 – 3–4 kalimat sederhana

💬 Contoh pendapat (Pakar Bandeng):
I think brackish method is better. It is cheaper. The equipment is simple. Beginner farmers can learn easily.

🎤 B1 – 6–8 kalimat + cohesive devices

💡 Contoh pendapat (Pakar Kerapu / Bandeng):
In my opinion, brackish method is more suitable for beginners. First, it has lower costs. For example, ponds are natural and need less technology. On the other hand, marine method needs filters and pumps. Nevertheless, marine method produces higher value fish. To conclude, beginners should start with brackish water.

👥 Kelompok pengamat: nilai kejelasan argumen (1–3).

✍️ D. Aktivitas 3 – Writing Reflection

Tema: “Tidak ada teknik terbaik, hanya teknik yang paling sesuai.”
“There is no best technique, only the most suitable one.”

📝 A2 – 4–5 kalimat sederhana

There is no best technique. Brackish water is good for milkfish. Marine water is good for grouper. Each technique is suitable for different fish. Choose the right technique for your fish.

✏️ B1 – 6–8 kalimat + alasan & contoh

There is no single best technique, only the most suitable one. For instance, brackish method works well for milkfish because they tolerate low salinity. However, grouper needs marine water to survive. Therefore, suitability depends on the fish species. Another example: a farmer near mangroves should choose brackish. In contrast, a farmer near the open sea can choose marine. So, always consider your location and target fish.

🧠 E. Refleksi (Reflection)

1. What did I learn about comparing nursery techniques?
Jawab singkat: Saya belajar bahwa ikan yang berbeda membutuhkan air yang berbeda. / I learned that different fish need different water.

2. How can I explain my opinion more clearly?
Jawab singkat: Dengan menggunakan contoh dan kata penghubung seperti “however” atau “for example”. / I can use examples and words like “however” or “for example”.
