UNDERSTANDING GROW-OUT STRATEGIES

PERTEMUAN 1: MEMAHAMI STRATEGI PEMBESARAN

MEETING 1: UNDERSTANDING GROW-OUT STRATEGIES

A. TUJUAN PEMBELAJARAN

• Mengidentifikasi karakteristik sistem budidaya intensif dan semi-intensif
• Menyusun argumen berbasis fakta untuk mendukung strategi tertentu
• Berpartisipasi aktif dalam debat konstruktif

B. MATERI INTI

1. Kosakata Kunci:

Intensive system Sistem budidaya dengan kepadatan tinggi, kontrol penuh, input tinggi

Semi-intensive system Sistem budidaya dengan kepadatan sedang, penggunaan pakan alami dan buatan

Stocking density Jumlah ikan per satuan luas (contoh: 20 ekor/m²)

Feed Conversion Ratio (FCR) Rasio pakan terhadap pertumbuhan (FCR 1.5 = 1.5 kg pakan untuk 1 kg ikan)

Sustainability Keberlanjutan, kemampuan sistem bertahan jangka panjang

2. Model Teks Opini:

WHY I CHOOSE INTENSIVE TILAPIA FARMING

I believe intensive farming is the best strategy for modern aquaculture. First, it maximizes production in limited space. With high stocking density, I can produce more fish in smaller ponds. Second, controlled environment reduces disease risk. I can monitor water quality daily and prevent problems. Finally, although feed costs are higher, the fast growth rate brings quicker profits. For example, my fish reach market size in 4 months instead of 6. Therefore, intensive systems offer economic advantages for commercial farms.

THE CASE FOR SEMI-INTENSIVE CULTURE

Semi-intensive systems provide better long-term sustainability. Firstly, they have lower environmental impact. Natural food sources reduce pollution from excess feed. Secondly, operational costs are 30-40% lower because less artificial feed is needed. Thirdly, fish are healthier with more natural behaviors. My experience shows survival rates are 15% higher in semi-intensive ponds. In conclusion, this balanced approach ensures both profit and environmental responsibility.
