Abstract

Work or activity is one of human activity that can not be avoided anymore. One such activity is the transfer of goods, the process of moving goods occurs both in the company and workers who are outside the company. Moving events occurring on the ice loading worker of the block occurs manually. Bending activity in bending due to overloading causes spinal cord injuries and other musculoskeletal disorders. In addition, the activity of moving goods also need to be considered in order to improve health and safety. On the results of the study Based on the calculation of the average force moment is 74425,72, this will make the pain in the spine so that in a certain time the body will turn into bending. The average energy consumption value is 3.6, this shows the energy consumption by the workers including the moderate category. For an average RWL value of 16.42 kg and a value (LI) with a load mass of 27 kg the mean LI value is 1.63, the value is highly at risk of causing spinal cord injury L5 / S1. After the proposed improvement work system on RWL and LI get the results of RWL value of 40.67 and LI of 0.6, the value of LI after the proposal has not caused injury on the vertebra L5 / S.


Kerja atau aktivitas merupakan salah satu kegiatan manusia yang tidak dapat dihindarkan lagi. Salah satu aktivitas tersebut adalah pemindahan barang, proses pemindahan barang terjadi baik diperusahaan maupun pekerja yang berada diluar perusahaan. Aktivitas pemindahan yang terjadi pada pekerja bongkar es balok terjadi secara manual. Aktifitas pengangkatan secara membungkuk yang disebabkan adanya pembebanan yang terlalu berat menyebabkan cedera tulang belakang dan gangguan otot lainnya (musculoskeletal disorder). Selain itu aktifitas pemindahan barang juga perlu diperhatikan guna meningkatkan kesehatan dan keselamatan kerja. Pada hasil penelitian Berdasarkan perhitungan momen gaya rata-rata adalah 74425,72, hal ini akan membuat sakit pada tulang belakang sehingga dalam waktu tertentu tubuh akan berubah menjadi membungkuk. Nilai konsumsi energi rata-rata adalah 3,6, hal ini menunjukkan konsumsi energi oleh para pekerja termasuk kategori moderat. Untuk nilai RWL rata-rata 16,42 kg dan nilai (LI) dengan massa beban 27 kg nilai LI rata-rata adalah 1,63, nilai tersebut sangat beresiko menyebabkan cedera tulang belakang L5/S1. Setelah dilakukan usulan perbaikan sistem kerja pada RWL dan LI mendapatkan hasil nilai RWL sebesar 40,67 dan LI sebesar 0,6, nilai LI setelah usulan sudah tidak menimbulkan cidera pada ruas tulang belakang L5/S1.
