CARA MENGHITUNG KEBUTUHAN INOKULAN GAHARU per POKOK

CONTOH PERHITUNGAN
KEBUTUHAN INOKULAN GAHARU TINGGI 40 Meter DAN PERIMETER 2 Meter dengan BOR POKOK UKURAN 1 INCH


Diketahui :
Tinggi Pokok 40 meter = 4000 cm
Perimeter Pokok 2 meter = 200 cm.
Jarak titik bor keatas = 15 cm
Diameter Bor pokok = 2.75 cm → r =1.375 cm


1. Diameter pokok = Perimeter : π = 200 cm : 3,14 = 63.69 cm

2. Jumlah titik lubang bor = Tinggi pokok : Jarak ttk bor keatas = 4000 cm : 15 cm = 267 lubang

3. Dalam lubang = 1/3 x diameter pokok = 1/3 x 63.69 cm = 21.23 cm.

4. Volume lubang pokok = 2 x π x r² = 2 x 3.14 x (1.375 cm)² = 9.81 cm³

5. Kebutuhan inokulan gaharu / lubang bor = volume x dalam lubang bor = 9.81 cm³ x 21.23 cm = 208.27 gram

6. Total kebutuhan inokulan gaharu per pokok = 208.27 gram x 267 lubang = 55608 gram = 56 kg


Keterangan :
1. perimeter = keliling lingkaran batang
2. diameter bor ukuran 13 mm = 2 cm
3. diameter bor ukuran 10 mm = 1 cm

EXAMPLE CALCULATION
Inoculant NEEDS AND aloes HIGH 40 Meters Perimeter 2 Meter with BOR OF SIZE 1 INCH

Given:
Principal High 40 meters = 4000 cm
Main Perimeter 2 meters = 200 cm.
Drill point distance = 15 cm and above
Drill Diameter principal = 2.75 cm → r = 1375 cm


1. Diameter principal = Perimeter: π = 200 cm: 3.14 = 63.69 cm

2. Number of points = High principal boreholes: Distance TTK drill upwards = 4000 cm: 15 cm = 267 holes

3. In hole = 1 / 3 x the diameter of the principal = 1 / 3 x 63.69 cm = 21:23 cm.

4. Volume staple holes = 2 x π x r ² = 2 x 3:14 x (1375 cm) ² = 9.81 cm ³

5. Needs inoculant aloes / = volume x drill hole in the drill hole = 9.81 cm ³ x 21:23 cm = 208.27 grams

6. The total requirement of aloes inoculant per subject = 208.27 grams x 267 hole = 55 608 grams = 56 kg
