Pemanfaatan Limbah Cair Tahu Sebagai Pemacu Pertumbuhan Bibit Geronggang (Cratoxylon Arborescens)
Cratoxylon arborescen is a local tree of peat swamp forest that has the
potential to be a candidate for planting in the initial phase of peat restoration.
Quality seeds will be produced from well-managed nurseries. One aspect of
nursery management is the provision of appropriate fertilizers and the right
dosage. Giving this fertilizer can be done using tofu liquid waste. The purpose of
this study was to determine the effect of tofu liquid waste on the growth of
Cratoxylon arborescen seedlings and determine the best composition of tofu
liquid waste to spur the growth of Cratoxylon arborescen seedlings. This research
was conducted with a completely randomized design method (CRD), which
consisted of 5 (five) treatments. Each treatment was repeated three times, so that
15 unit experiments could be obtained. Each experimental unit consists of five
plants so that the total plant is 75 units. Concentration of tofu liquid waste for
Cratoxylon arborescen seedlings is without giving (control) (P0), 20% (P12),
40% (P2), 60% (P3), and 80% (P4). The results showed that the application of
tofu liquid waste affected the growth of Cratoxylon arborescen seedlings. The
best composition of giving tofu liquid waste is giving tofu liquid waste as much as
20% (P1) with a yield of 100% life, height growth of 16.84 cm, seed diameter of
3.60 mm, plant dry weight of 4.18 gr and the top-root ratio of 2.72.
