Analisis Postur Kerja dalam Operasi Pemanenan Kayu: Pemuatan Log Secara Manual

Abstract

Lifting, pushing, and pulling activities combined with excessive material load and intense repetition have been reported to trigger excessive pressure on the lumbar disk (L5/S1). Using a static biomechanical approach (3DSSPP Version 7 software), this study presents empirical evidence proving that log loading activities with manual techniques are jobs that pose a high risk of injury to workers, indicated by (1) very high lifting index value (10), (2) compressive force that exceeds the maximum permissible limit of 6500 N, (3) difficult standing balance control, and (4) high potential of localized musculoskeletal fatigue in the workers. Musculoskeletal disorders analysis (using the Standardized Nordic Questionnaire instrument) shows intense disturbances in the lower back, shoulders, upper back, and hands. Interventions to reduce injury to the workers can be carried out by substituting work techniques (using aids devices), improving work administration (improving the standard operating procedure, supervision), and wearing anti-slip work shoes.

“…MSDs were also reported in the right and left legs (thighs, back of the knee, and calf, Figure 3) because the worker also works in a squatting position (Figure 4). The WBS results ( Figure 5) also verified that squatting posture potentially triggers excessive pressure on the vertebrae, resulting in musculoskeletal injury and chronics low back pain (Kroemer and Grandjean 1997;Kumar 2001;Sakka et al 2015;Yovi and Andriyani 2019).…”

“…Forest product harvesting refers to extracting forest products from the forest to the market place for a benefit value. Due to the type of commodity, resources, and social context, forest product harvesting activities in Indonesia are carried out at various levels of technological application, ranging from the conventional or manual system (labor-intensive) to semimechanical system (Yovi and Andriyani 2019). Regardless of the level of technology used, this operation has a high-risk that may threaten the worker's occupational safety and health (Lindroos and Burström 2010;Potočnik et al 2009;Tsioras et al 2014;Yovi 2019;Yovi and Yamada 2019).…”

Analysis of OSH risk level in forest management activities using remote sensing approach in RPH Takokak, KPH Sukabumi, West Java Province

“…This effort is the most appropriate level of Control to be applied in forest management activities. Yovi dan Andriyani [52] explains, Managerial parties need to provide assignments, skills, and appreciation to support the success of work productivity. This includes procedures for preparing SOPs to accommodate proper and good work attitudes for each worker.…”

Implementing Occupational Safety and Health Management System in a Forest Management Unit (FMU) X: A Financial Analysis

“…Demikian halnya pada kegiatan penebangan, yang menuntut pada pekerjaan yang berat seperti menebang menggunakan gergaji mesin dan mengangkut log yang berat. Jika pekerja sering berada dalam situasi ini maka berpeluang menderita penyakit akibat kerja (Yovi & Prajawati, 2015;Yovi & Andriyani, 2019). Hal ini mewajibkan perusahaan memberikan layanan pemeriksaan kesehatan kepada pekerja yang dilakukan secara berkala untuk mencegah pekerja mengalami penyakit akibat kerja.…”
