dc.description.abstract | Kegiatan penebangan termasuk dalam kegiatan pemanenan hutan dengan
risiko kerja tinggi yang disebabkan oleh beberapa faktor, diantaranya kondisi areal
hutan yang tidak dapat dijangkau, kurangnya pengetahuan dan keterampilan
operator, tidak seimbangnya peralatan yang digunakan dengan kemampuan
operator dan mengangkat beban yang berlebihan sehingga menimbulkan rasa sakit
pada tubuh operator. Kegiatan penebangan pohon jati (Tectona grandis Linn.)
menggunakan chainsaw melibatkan bagian tubuh bahu, punggung dan lutut yang
paling sering mengalami cedera berupa keluhan nyeri pada L5/S1 akibat menerima
beban terlalu tinggi. Postur tubuh ekstrem dipilih melalui analisis Range of Motion
(ROM), kemudian dilanjutkan analisis biomekanik. Postur ekstrem yang terpilih
disimulasikan menggunakan software 3DSSPP 7.1.0. Analisis yang dihasilkan dari
software 3DSSPP meliputi besarnya compression force dan shear force pada L5/S1,
strength percent capable dan standing balance. Postur yang menghasilkan
compression force >3400 N dan shear force >500 N, perlu dilakukan perhitungan
Recommended Weight Limit (RWL) dan Lifting Index (LI) untuk
merekomendasikan batas beban yang dapat diangkat oleh operator tanpa terjadi
peningkatan risiko nyeri pada L5/S1. | id |
dc.description.abstract | Logging activities are included in forest harvesting activities with high work
risk caused by several factors, including the condition of the forest area that can’t
be reached, lack of operator knowledge and skills, imbalance of equipment used
with the operator’s ability and lifting excessive weight that cause pain in the
operator body. Teak tree felling (Tectona grandis Linn.) using a chainsaw involves
the shoulders, back and knees which are the most frequently injured in the form of
complaints of pain in L5/S1 due to receiving too high a load. Extreme body postures
were selected through Range of Motion (ROM) analysis, then followed by
biomechanical analysis. The selected extreme posture is simulated using 3DSSPP
7.1.0 software. The analysis generated from 3DSSPP software includes the
magnitude of compression force and shear force at L5/S1, strength percent capable
and standing balance. Postures that produce compression force >3400 N and shear
force >500 N, need to be calculated Recommended Weight Limit (RWL) and
Lifting Index (LI) to recommend the load limit that can be lifted by the operator
without increasing the risk of pain in L5/S1. | id |
