| Summary: | The study was conducted to determine the ripeness of durian (Durio zibhetinus) by specific gravity. Total sampel were 32 duriarts, consited of 16 unripe durians and 16 ripe durians. Durians was colected from Bogor. Specific gravity of durians was measured by water displacement method and then the durians were opened to check the ripeness. Firmness and total soluble solid were determined to reveal the ripeness of flesh.
The specific gravity of ripe durian was (0.824± 0.03) g/cm3 whereas for unripe durian was (0.949 ± 0.03) g/cm3. The firmness of ripe durian was (5.99 ± 4.04) N and unripe one was (43.48 ±5.39) N. The total soluble solid of ripe durian was (43.48 ±5.39) % brix and unripe one was (6.91 ±1.30) % brix. The relationship of specific gravity (BJ) with the flesh of durian firmness and total soluble solid were fairly high with the correlation coefficients of 0.86 and 0.91 respectively.
