Fakta tentang MH

• Material Handling melibatkan:– 25% dari seluruh karyawan– 55% dari seluruh area pabrik– 87% dari waktu produksi– 15-70% dari biaya total produk yang diproduksi

• 3-5% dari seluruh material yang ditangani menjadi rusak– Benar-benar tereliminasi (value)– Namun, handling lebih sedikit bukan solusi.

Tujuan Material Handling

– Mengurangi biaya manufacturing total melalui:• Persediaan berkurang• Keamanan meningkat• Pencurian berkurang• Pengendalian material meningkat

– Kualitas manufacturing lebih baik dengan:• Mengurangi persediaan• Mengurangi kerusakan

– Save money, save time, save man

Defenisi MHS

•Material handling adalah seni dan ilmu dari perpindahan (moving), penyimpanan (storing), proteksi (protecting), dan pengendalian (controlling) material

– Moving: diperlukan untuk membuat utilitas waktu dan tempat. Nilaimemiliki material pada waktu yang tepat dan tempat yang tepat.

– Storing: Menjadi penyangga antara operasi, memfasilitasipenggunaan orang dan mesin secara efisien.

– Protecting: termasuk pengemasan, kemasan dari kerusahkan danpencurian.

– Controlling: Fisik: orientasi, urutan, dan ruang antara material.Status: Real-time awareness terhadap lokasi, jumlah, destinasi, asal,

kepemilikan, dan jadwal material.

Materials Handling Systems (MHS)

• MHS adalah sekelompok equipment yang memungkinkanpergerakan fisik dalam rantai distribusi – termasuk rantaiproduksi dan gudang – dari bahan baku, bahan dalam proses dan produk akhir.

• Karenanya, sistem material handling melibatkan serangkaianaktivitas.

• Umumnya, materials handling berkaitan dengan tugas-tugasyang harus dilakukan untuk tujuan memindahkan beban di sekitar lantai pabrik untuk disimpan atau dipindahkan.

• Materials handling dilakukan dengan satu atau lebih cara di sepanjang rantai pasok termasuk fungsi produksi, distribusi, penyimpanan, dan retail.

• Handling in a warehouse or distribution center will have a major impact on how effectively materials flow through the system, and on the cost, resource and time taken to get orders out to the customer.

• In addition, handling equipment can be capital –intensive, and the act of movement can be labour –intensive.

• Material handling equipment eases manual handling chores and enhances operational efficiency.

• Various methods of handling goods are used in warehousing, from manual through to automated or robotic systems, and a broad categorization could be: – Manual handling; – Manually operated trucks and trolleys; – Powered trucks and tractors, operator controlled and

driven; – Powered trucks and trolleys, driverless, computer-

controlled; – Crane systems; – Conveyors; – Robotics

• The factors to be considered when deciding on the appropriate type of handling system for a particular application include: – Types of load being handled including the unit load

characteristics; – Quantity of material being handled; – Frequency of movement; – Distances to be travelled, horizontal and vertical; – Numbers and locations of pick-up and drop points;– Adjacent activities; – Nature of terrain; – Flexibility required

Handling system are classified as

– mechanized, – semi automated, – automated, and– information- driven.

• The What Question1. What are the types of material to be moved?2. What are their characteristics?3. What are the amounts moved and stored?

• The Where Question1. Where is the material coming from? Where should

it come from?2. Where is the material delivered? Where should it

be delivered?3. Where is the material stored? Where should it be

stored?4. Where can material handling tasks be eliminated,

combined or simplified?5. Where can you apply mechanization or automation?• The When Question1. When is material needed? When should it be

moved?2. When is it time to mechanize or automate?3. When should we conduct a material handling

performance audit?

•The How Question1. How is the material moved or stored? How should

material be moved or stored? What are the alternative ways of moving or storing the material?

2. How much inventory should be maintained?3. How is the material tracked? How should the

material be tracked?4. How should the problem be analyzed?•The Who Question1. Who should be handling material? What are the

required skills to perform the material handling tasks?

2. Who should be trained to service and maintain the material handling system?

3. Who should be involved in designing the system?•The Which Question1. Which material handling operations are necessary?2. Which type of material handling equipment, if any,

should be considered?3. Which material handling system is cost effective?4. Which alternative is preferred?
