Increasing Of White Pepper Quality by Submersion Period and Additional of Karamunting Leaf (Melastoma malabathricum)
Peningkatan Kualitas Lada Putih dengan Kombinasi Lama Perendaman dan Penambahan Daun Karamunting (Melastoma malabathricum)
Pepper submersion period with addition karamunting leaf (Melastoma malabathricum) is one expected postharvest to increasing white pepper quality.
