ABSTRAK
WL Aluminium merupakan Usaha Kecil Menengah (UKM) yang memproduksi
berbagai produk aluminium peralatan rumah tangga seperti wajan, panci, ketel, sobok dan
lain-lain. Pada proses pembuatan wajan yang dilakukan pekerja, tedapat keluhan-keluhan
yang timbul akibat posisi kerja yang salah dan sarana/fasilitas kerja yang digunakan kurang
mendukung. Posisi kerja tidak normal saat melakukan aktivitas seperti membungkuk dapat
menimbulkan keluhan Musculoskeletal Disorders (MSDs). Postur kerja ini melibatkan
punggung pada tulang belakang sehingga dapat terjadi Low Back Pain yaitu nyeri pada
tulang belakang, tepatnya pada Lumbar 5/Sacrum 1 (L5/S1).
Penelitian ini menggunakan Model Biomekanika sebagai solusi dalam perbaikan
postur kerja. Model Biomekanika menjadi penyelesaian permasalahan dalam penelitian ini,
berguna untuk mengetahui besar gaya tekan pada persendian L5/S1 setiap pekerja. Tahap
selanjutnya menentukan dan menghitung data antropometri pekerja di WL Aluminium
yang dibutuhkan dalam membuat usulan rancangan sarana/fasilitas kerja.
Hasil analisis postur kerja menggunakan Model Biomekanika diperoleh gaya tekan
(FC) > AL (batas gaya angkat normal: 3500 N) pada pekerja di stasiun kerja pengecoran
aktivitas peletakkan dan pembukaan cetakkan wajan sebesar 5124,67 N dan 5118,09 N,
sehingga memerlukan perbaikan. Perbaikan dengan merancang dan mengimplementasikan
alat bantu meja cetakkan wajan di stasiun kerja pengecoran. Pengukuran gaya tekan pada
persendian L5/S1 dari hasil implementasi alat bantu meja cetakkan wajan mengalami
penuruanan gaya tekan (FC) < AL (batas gaya angkat normal: 3500 N) pada aktivitas
peletakkan dan pembukaan cetakkan wajan sebesar 3154,42 N dan 2788,83 N.

ABSTRACT
WL Aluminum is a Small and Medium Enterprise (SME) that produces various
aluminum household products such as frying pans, pots, kettles, sobok and others. In the
process of making wok by workers, there are complaints that arise due to the wrong work
position and the work facilities/facilities used are not supportive. Abnormal working
positions when doing activities such as bending over can cause complaints of
Musculoskeletal Disorders (MSDs). This work posture involves the back to the spine so
that Low Back Pain can occur, namely pain in the spine, to be precise in Lumbar 5/Sacrum
1 (L5/S1).
This study uses the Biomechanics Model as a solution in improving work posture.
The Biomechanics model is the solution to the problem in this study, it is useful for knowing
the magnitude of the compressive force on the L5/S1 joints of each worker. The next stage
is to determine and calculate the anthropometric data of workers in WL Aluminum which
is needed in making proposals for the design of work facilities/facilities.
The results of the analysis of work posture using the Biomechanics Model obtained
that the compressive force (FC) > AL (normal lifting force limit: 3500 N) on workers at
the casting work station, placing and opening the pan mold is 5124.67 N and 5118.09 N,
so it requires improvement. . Improvements by designing and implementing pan mold table
aids in foundry work stations. The measurement of the compressive force at the L5/S1 joints
from the results of the implementation of the frying pan table tool experienced a decrease
in the compressive force (FC) < AL (normal lifting force limit: 3500 N) in the activity of
placing and opening the pan mold by 3154.42 N and 2788.83 N.
