1. TONASE = ( T" x L" x P' x Pcs ) / 7200

2. M3 = ( T" x L" x P' x Pcs x 1.416) / 7200

3. CFt = ( T" x L" x P' x Pcs ) / 144

4. Running Feed = P x Pcs
         > P' x Pcs = RF

         > ( P" x Pcs ) / 12 = ( Pmm x Pcs) / (25.4 x 12 )

         > Ton x 50 = CFt
             CFt / 50 = Ton

         > M3 / 1.416 = Ton
            Ton x 1.416 = M3

PERHITUNGAN BERAT CONTAINER

1. Buyer : Dong Myung

2. Size :

2.1. Profile : 32 x 78 x 2100 = 7616 Pcs = 39.9200 M3

2.2. S4S FJL : 41 x 201 x 3650 = 120 Pcs = 3.6096 M3

41 x 141 x 3650 = 154 Pcs = 3.2495 M3

Total 6.8591 M3

3. Perhitungan Berat

3.1. Berdasarkan Rumus

* Profile = 39.9200 M3 x 888.6 kg x 75% = 26.604.68 Kg

* S4S FJL = 6.8591 M3 x 888.6 kg = 6.095.20 Kg

* Berat Container = 9.960 Kg

Total = 42.659.88 Kg

3.2. Berdasarkan Timbangan

* Profile = 7616 pcs x 3.1 kg = 23.609.6 Kg

* Palet = 17 plt x 30 kg = 510 Kg

* S4S FJL = 154 pcs x 14 kg = 2.656 Kg

( 41 x 141 x 3650 )

* S4S FJL = 120 pcs x 18.3 kg = 2.196 Kg

( 41 x 210 x 3650 )

* Palet = 2 plt x 60 kg = 120 Kg

* Berat Container = 9.960 Kg

Total = 39.051.6 Kg

Keterangan :

Berat Maksimum Container = 42.460 Kg

CARA MENGHITUNG VOLUME (M3)

1. Tebal Inch ( " ), Lebar Inch ( " ), Panjang Feet ( ' )
     Rumus : T" x L" x P' x Pcs : 7200 x 1.416

2. Tebal Inch ( " ), Lebar Inch ( " ), Panjang Inch ( " )
     Rumus : T" x L" x P" x Pcs : 12 : 7200 x 1.416

3. Tebal mm, Lebar mm, Panjang mm
     Rumus : T mm x L mm x P mm x Pcs : 1.000.000.000

4. Tebal mm, Lebar mm, Panjang Feet ( ' )
     Rumus : T mm x L mm x P' x 0.3048 x Pcs : 1.000.000

5. Tebal mm, Lebar Inch ( " ), Panjang Feet ( ' )
     Rumus : T mm : 25.4 : L" x P' x Pcs : 7200 : 1.416

6. Tebal mm, L mm, Panjang Inch ( " )
     Rumus : T mm x L mm x P" : 12 x 0.3048 x Pcs : 1.000.000

7. Tebal Inch ( " ), Lebar Inch ( " ), Panjang meter (M)
     Rumus : T" x L" x P(M) x 3.2808 x Pcs : 7200 x 1.416

8. Tebal Inch ( " ), Lebar mm, Panjang meter (M)
     Rumus : T" x L mm x P (M) x 25.4 x Pcs : 1.000.000

9. Tebal Inch ( " ), Lebar mm, Panjang mm
     Rumus : T" x L mm x Pmm x 25.4 x Pcs : 1.000.000.000

RUMUS DOWEL (M3)
1. Diameter dalam inch ("), panjang inc(")
Rumus : P" : 12 x Pcs x D2" : 12 x 0.7854 : 600 x 1.416

2. Diameter dalam (mm), panjang (mm)
Rumus : D2 mm x P mm x Pcs x 0.7854 : 1.000.000.000

3. Diameter dalam inch ("), Panjang Feet(')
Rumus : D2" x P' x Pcs : 12 x 0.7854 : 600 x 1.416

4. Diameter dalam mm, Panjang (M)
Rumus : D2 mm x P (M) x Pcs x 0.7854 : 1.000.000

RUMUS PERHITUNGAN :
1. Keliling Log :
~ K = л X D , atau
~ K = 2 X л X R , atau
~ K = л X ( R + R )

Keterangan :
K = Keliling
л = ²²/₇ = 3.14
D = Diameter
R = Jari-jari

2. Volume Log
~ Volume (M3) = D² MM X P MM Btg x 0.7854 : (rata-rata) 1.000.000.000 atau
~ Volume (M3) = л X R² X P X Btg

Keterangan :
D = Diameter
R = Jari jari ( diameter : 2 )
P = Panjang
Btg = Batang

RUMUS PERHITUNGAN CUTTER MARK

CM : Cutter Mark
H    : Height of Cutter Mark

               F x 1000
CM = ------------------
              V x N

Dimana : CM : Bekas kerata / serutan (mm)
                   F : Kecepatan pengumpan ( m/menit)
                   V : Kecepatan Poros ( RPM)
   N : Jumlah pisau

RUMUS PERHITUNGAN "C" ( CORNELL )

Contoh : C2

Rumus : √ C x 2

Maka panjang C2 = √ 2 x 2 = 1.4 mm x 2 = 2.8 mm
