# Kalkulator Recovery Penggergajian

Lumber recovery rate dan overrun log rule — dibenchmark terhadap data FAO dan Eropa.

Masukkan volume kayu bulat yang masuk pabrik dan volume kayu gergajian yang keluar untuk mendapat recovery rate, dibenchmark terhadap rentang referensi FAO, Eropa, dan Asia Tenggara. Opsional: tambahkan board foot log rule dan board foot gergajian aktual untuk menghitung overrun atau underrun Doyle/Scribner.

## FAQ

Berapa lumber recovery rate yang bagus?

Tergantung wilayah dan kualitas batang: pabrik kayu keras Eropa rata-rata sekitar 38%, kayu lunak 48%, dan survei global FAO melaporkan 42–60% dengan rata-rata 50.8%. Pabrik hutan tanaman tropis di Asia Tenggara mencapai sekitar 52% dengan gergaji pita tapi hanya 39% dengan gergaji rantai.

Apa itu overrun log rule?

Log rule mengestimasi board foot yang seharusnya dihasilkan satu batang. Overrun adalah persentase produksi aktual di atas rule: (aktual − rule) ÷ rule × 100. Aturan Doyle merendahkan batang kecil, jadi pabrik yang membeli dengan Doyle sering menggergaji 10–30% overrun; batang besar bisa menunjukkan underrun. International 1/4″ adalah aturan paling akurat.

Bagaimana memperbaiki recovery di pabrik gergaji kecil?

Gergaji pita membuang kerf lebih sedikit daripada gergaji rantai atau bundar (data Asia Tenggara menunjukkan 52% vs 39%), mata tipis yang tajam (thin-kerf), penempatan batang dan edging yang hati-hati, serta menjual panjang lebih pendek semuanya menaikkan recovery. Mencatat recovery per partai batang terhadap benchmark di atas adalah langkah pertama.
