LAMPIRAN EWAKTU EDAR ALAT GALI MUAT EXCAVATOR KOMATSU PC 1250SP-8 DAN PC 2000-8

Perhitungan waktu edar ( cycle time ) alat mekanis dilakukan dengan cara memperhatikan pola gerak alat mekanis pada saat melakukan aktifitasnya. Waktu edar alat muat adalah jumlah waktu yang dihabiskan dalam satu kali rangkaian kerja mulai dari mengambil posisi penggalian sampai kembali kosong untuk kembali menggali.Waktu edar ( cycle time ) alat muat dapat dirumuskan sebagai berikut :

CTm = T1 + T2 + T3 + T4

Dimana :

CTm = Cycle time/ total waktu edar alat muat

T1 = waktu untuk mengisi muatan

T2 = waktu untuk mengayun bermuatan T3 = waktu untuk menumpahkan muatan T4 = waktu untuk mengayun kosong

LAMPIRAN FWAKTU EDAR ALAT ANGKUTKOMATSU HD 785 (Kombinasi PC 1250 SP-7 dan PC 2000-8)

Waktu edar ( cycle time ) untuk alat angkut dapat dirumuskan sebagai berikut :

CT = T1 + T2 + T3 + T4 + T5 + T6

Dimana :

CTa = Total waktu edar alat angkut

T1 = Waktu untuk mengatur posisi untuk diisi muatan

T2 = Waktu untuk diisi muatan

T3 = Waktu untuk mengangkut muatan

T4 = Waktu untuk mengatur posisi untuk menumpahkan muatan

T5 = Waktu untuk menumpahkan muatan

T6 = Waktu kembali untuk diisi dalam keadaan kosong

Berdasarkan pengamatan di lapangan di diperoleh data pengukuran waktu edar Komatsu HD785 dengan kombinasi Komatsu PC1250 SP-7 dan Komatsu PC2000-8 sebagai berikut:Tabel.Data Waktu Edar Komatsu HD 785 pada Komatsu PC 1250 SP-7No.T1T2T3T4T5T6Cycle Time

LAMPIRAN HPERHITUNGAN PRODUKTIVITAS ALAT GALI MUAT DAN ALAT ANGKUT

PRODUKTIVITAS ALAT MUAT

Keterangan:Qm = Kemampuan produksi alat muat (BCM/jam)

Ct = Waktu edar alat muat sekali pemuatan (menit) Cm = Kapasitas baku mangkuk alat muat (m3)FF = Faktor pengisian (%) E = Effisiensi kerja (%) Sf = Swell factor

Berdasarkan data hasil pengukuran di lapangan : Produksi Excavator Komatsu PC1250SP-8 Nomor Unit EX1037CTm = 24,01 detik = 0.40 menitCm = 6.7 m3

FF = 0.9

E= 80% Sf = 0,74

Berdasarkan data hasil pengukuran di lapangan : Produksi Excavator Komatsu PC 2000-8 Nomor Unit EX1769CTm = 0.51 menit

Cm = 12 m3

FF = 0.9

E= 79% Sf = 0,74


Cm = 12 m3

FF = 0.9

E= 75% Sf = 0,74


Cm = 12 m3

FF = 0.9

E= 86% Sf = 0,74

PRODUKTIVITAS ALAT ANGKUT

Qa= Kemampuan produksi alat angkut (BCM/jam)Na= Jumlah Alat Angkut (unit)Ca = Kapasitas bak alat angkut (BCM)= n x Cm x FCt= Waktu edar (menit)F = Faktor pengisian

Berdasarkan data hasil pengukuran di lapangan:Produksi Dump Truck Komatsu HD785-7 pada Alat Muat EX1037Cta= 866,75detik = 14,45menitNa= 4 UnitCa= 43 BcmSf= 0,74 E= 75%
