Proyek konstruksi memiliki tekanan bagi para pekerja, sehingga memicu kelelahan, penyakit akibat kerja, sehingga menurunkan produktivitas. Pekerja melakukan penanganan material yang tidak tepat menggunakan Manual Material Handling, menyebabkan pekerja mengalami nyeri pada bagian tubuh. Otot para pekerja menerima beban statis terus-menerus dalam jangka waktu lama berpotensi mengakibatkan gangguan muskuloskeletal. Tujuan penelitian untuk menganalisis postur kerja para pekerja proyek konstruksi pembangunan Jembatan Mlowo, Cs Nguter Sukoharjo. Penelitian ini menggunakan metode penelitian eksperimental di lokasi proyek, kemudian dianalisis menggunakan kuesioner CMDQ dan metode REBA. Terdapat 7 aktivitas yang dianalisis dalam penelitian ini, sebab memiliki tingkat risiko tinggi dan dilakukan berulang, antara lain aktivitas penulangan, pemindahan baja tulangan, pengecoran (menahan bak penuang cor), pemasangan bagesting, pengecoran (mengalirkan cor), pemindahan girder, dan pemindahan las listrik. Hasil penelitian menunjukkan bahwa semua aktivitas memerlukan proses perbaikan. Berdasarkan kuesioner CMDQ, bagian tubuh yang sering dirasakan nyeri oleh pekerja adalah lengan atas. Penilaian dengan REBA, penulangan skor 7 (perlu perbaikan), pemindahan baja tulangan skor 10 (harus segara perbaikan), pengecoran (menahan bak) skor 11 (saat ini dilakukan perbaikan), pemasangan bagesting skor 7 (perlu perbaikan), mengalirkan pengecoran skor 9 (segera perbaikan), pemindahan girder skor 12 (perbaikan saat ini), dan pemindahan las listrik skor 10 (segera perbaikan).

Workload related to material handling is one of main biomechanical risks that cause work related musculoskeletal disorderat work. The aim of this study wasto assess the risk factors for biomechanical loading present at carried out tasks by port stevedores. First, we made a diagnosis using the risk assessment matrix (RAM) then; we evaluated the biomechanical risk using the NIOSH lifting equation (Compound method). The results were a high level of unacceptable risk at the beginning and at the end of the task (scored 4.22 and 8.50 respectively). Subsequently, we made a correlation analysis between this scored and the musculoskeletal discomfort perceived by stevedores. From this analysis, it is evident that there is a direct relation between lifting vertical distance, trunk torsion, and the increase of musculoskeletal lesions suffered by the dockers. Finally, we proposed some methods to improve the activities of filling and emptying containers and minimize the manual material handling.

Rapid Entire Body Assessment

CV Tirta Mineral merupakan perusahaan distributor air mineral cara memindahkan galon masih menggunakan tenaga manual atau biasa disebut manual material handling (MMH). Postur tubuh pada saat bekerja yang kurang tepat berpotensi mengakibatkan terjadinya cedera otot atau cedera sistem muskuloskeletal yang disebut Musculoskeletal Disorders (MSDs). Penelitian ini untuk mengetahui gangguan postur tubuh yang terjadi pada pekerja maka dipergunakan metode REBA (Rapid Entire Body Assessment). Metode ini digunakan untuk mengukur aktivitas pekerjaan yang bersifat manual. Pengukuran dilakukan terhadap pekerja yang melakukan proses pengangkatan galon air mineral di salah satu perusahaan UMKM di daerah Cileungsi.  Hasil penelitian ini menunjukan bahwa postur kerja yang analisis mempunyai level resiko yang tinggi, yaitu skor 8 sampai 10, nilai tersebut sangat beresiko menyebabkan cedera yang berarti perlu adanya perbaikan segera. Perbaikan yang dilakukan berupa usulan alat bantu bagi pekerja berupa troli, diharapkan dengan troli tersebut mampu menghindari resiko terjadinya cedera serta memperbaiki postur kerja.

Manual Material Handling (MMH) duringmaintenance activities poses strain to employees and at times it results in injuries. This type of work entails lifting, bending and twisting which can cause great strain to the human body if done improperly. A paradigm shift has taken place in Ergonomics from the narrow to a wide approach dealing with physiological, psychological, technological and organizational aspects of human work environment. This paper analyses the MMH hazards during the replacement of jaw bits in Electrically Operated Tong (EOT) crane in Hot Rolling Mill. Ergonomics risk factors were estimated using Rapid Entire Body Assessment risk assessment (REBA) tool. Based on the analysis, suitable engineering improvement called Lift - Assist Device was developed to reduce extreme range of motion while lifting, moving and inserting and found to be satisfactory.

Rapid Entire Body Assessment

In doing a job manually such as moving, lifting a certain material needs to be evaluated to minimize the risk of work accidents. The research that will be conducted is the evaluation of manual material handling on the removal and removal of thiners. The purpose of this study was to determine the application of work biomechanics in minimizing the risk of spinal cord injury and providing improvement in work activities. The methods used in this research are Nordic Body Map, NIOSH, Rapid Entire Body Assessment, L5 / S1 (Fc) Force and Energy Consumptions. The results of this study were found that several parts of the workers' body muscles were injured, such as the neck, left and right shoulders, arms and wrists, back and waist. The RWL and Li values ​​after repairs where is RWL exceeded the Load Constant value of 20 kg, and the Li value <1 (no risk). Then the work category level which was originally light-moderate work changed to light work. Furthermore, the original REBA score got a score of 5 to 3 (level 1). And the results of the compressive force against L5 / S1 have values ​​of Fc <AL and Fc < MPL.
