Hubungan Masa Kerja, Postur Kerja dan Beban Kerja Mental dengan Keluhan Musculoskeletal Disorders pada Pemanen Kelapa Sawit di PT.Gersindo Minang Plantation, Kabupaten Pasaman Barat Tahun 2017

Abstract

Tujuan Penelitian Pekerjaan yang masih dilakukan secara manual menuntut kemampuan tulang dan otot. Aktivitas pemanenan kelapa sawit masih dilakukan secara manual dan berisiko untuk mengalami keluhan muskuloskeletal. Penelitian ini bertujuan untuk mengetahui hubungan antara umur, masa kerja, postur kerja dan beban kerja mental dengan keluhan MSDs pada pemanen kelapa sawit di PT.Gersindo Minang Plantation, Kab.Pasaman Barat, Sumatera Barat. Metode Penelitian dilakukan pada bulan Februari-April 2017 dengan menggunakan desain studi cross sectional. Dari 165 populasi didapatkan sampel sebanyak 65 responden dengan teknik pengambilan simple random sampling. Postur kerja dianalisis dengan menggunakan metode Rapid Entire Body Assessment (REBA), keluhan muskuloskeletal dinilai dengan kuisioner Nordic Body Map, beban kerja mental dinilai dengan kuesioner NASA-TLX, umur dan masa kerja didaapatkan dari wawancara kepada responden. Hasil Hasil penelitian menunjukkan jumlah responden yang mengalami keluhan MSDs berat sebanyak 28 responden dan yang mengalami keluhan MSDs ringan sebanyak 37 responden. Hasil uji chi square menunjukkan bahwa umur (p-value:0.000), masa kerja (p-value:0.018), dan postur kerja (p-value:0.002) berhubungan dengan terjadinya keluhan MSDs. Sedangkan beban kerja mental ditemukan tidak berhubungan dengan terjadinya keluhan MSDs. Kesimpulan Variabel umur, masa kerja dan postur kerja berhubungan dengan terjadinya keluhan MSDs. Untuk mengurangi risiko terjadinya MSDs, perusahaan diharapkan melakukan pelatihan tekait postur kerja beresiko, mengatur waktu kerja dan melakukan relaksasi otot pada saat bekerja.

Oil palm harvesting was conducted manually and have some risks to cause Musculosceletal disorders (MSDs). This study was aimed to determine the relationship between age, working periode, working posture and mental work load with the occurence of MSDs complaints on oil palm harvesters in PT.Gersindo Minang Plantation district west pasaman, west sumatera province Method This research conduct from February until April 2017 using a design cross sectional study. The sample were 65 harvesters from 165 population with simple random sampling technique. Work postures were analyzed using Rapid Entire Body Assessment (REBA) methods, musculoskeletal disorders assessed by Nordic Body Map questionnaire, mental workload assessed by NASA-TLX questionnaire, age and working periode obtained from interviews with respondents. Result The result showed 28 harvesters suffered severe MSDs and 37 harvesters suffered milds MSDs. Chi square test result showed that age (p-value:0.000), working period (p-value:0.018), working posture (p-value:0.002) were associated with MSDs complaints. Meanwhile the mental workload statistically unrelated with the MSDs complaints (p-value:1.00). Conclusion Age, working periode and working posture were related to MSDs complaints. To minimize the risk of MSDs complaints, the oil palm company expected to do training and education about working posture, manage time of work and the harvesters expected to stretch and rest the muscle during work.
