Intervensi Suplemen Asam Lemak Omega-3 Terhadap Penurunan Keluhan Muskuloskeletal Disorders (MSDs) pada Penenun Ikat Tradisional di Kelurahan Fatubenao Kecamatan Kota Atambua Kabupaten Belu

ABSTRACT Musculoskeletal Disorders (MSDs) are a major occupational health problem in the informal sector, particularly among traditional weavers who work in repetitive postures for extended periods. Traditional ikat weavers in Fatubenao Village, Atambua City, Belu Regency, experience significant musculoskeletal complaints due to prolonged awkward postures. This study aimed to analyze the effect of omega-3 fatty acid supplementation in reducing musculoskeletal disorder complaints among traditional ikat weavers. A quasi-experimental study with a non-equivalent control group design was conducted on 30 respondents (15 intervention, 15 control). MSDs complaints were measured using the Nordic Body Map (NBM) instrument covering 28 body regions. Omega-3 supplementation was administered for 14 days. Data analysis used the Wilcoxon Signed Ranks Test and Mann-Whitney Test. The highest MSDs complaints prior to intervention were found in left and right ankle (76.7%), lower back (73.3%), left wrist (70.0%), and left upper arm (63.3%). Wilcoxon test showed significant reduction in the intervention group (Z = -3.417; p = 0.001). Mann-Whitney posttest revealed a significant difference between intervention and control groups (U = 54.000; p = 0.014). Omega-3 fatty acid supplementation for 14 days significantly reduced MSDs complaints among traditional ikat weavers. This non-pharmacological intervention is safe, affordable, and effective for controlling MSDs in informal sector workers.

ABSTRAK Musculoskeletal Disorders (MSDs) merupakan masalah kesehatan kerja utama di sektor informal, khususnya pada penenun ikat tradisional yang bekerja dalam postur berulang dalam durasi lama. Penenun ikat tradisional di Kelurahan Fatubenao, Kecamatan Kota Atambua, Kabupaten Belu mengalami keluhan muskuloskeletal yang signifikan akibat postur kerja tidak ergonomis yang berkepanjangan. Penelitian ini bertujuan menganalisis efektivitas suplementasi asam lemak omega-3 dalam menurunkan keluhan Musculoskeletal Disorders (MSDs) pada penenun ikat tradisional. Studi kuasi-eksperimental dengan desain non-equivalent control group dilakukan pada 30 responden (15 kelompok perlakuan, 15 kelompok kontrol). Keluhan MSDs diukur menggunakan instrumen Nordic Body Map (NBM) mencakup 28 area tubuh. Suplemen omega-3 diberikan selama 14 hari. Analisis data menggunakan Uji Wilcoxon Signed Ranks Test dan Mann-Whitney Test. Keluhan MSDs tertinggi sebelum intervensi ditemukan pada pergelangan kaki kiri dan kanan (76,7%), punggung bawah (73,3%), pergelangan tangan kiri (70,0%), dan lengan atas kiri (63,3%). Uji Wilcoxon menunjukkan penurunan signifikan pada kelompok perlakuan (Z = -3,417; p = 0,001). Uji Mann-Whitney posttest menunjukkan perbedaan bermakna antara kelompok perlakuan dan kontrol (U = 54,000; p = 0,014). Suplementasi asam lemak omega-3 selama 14 hari secara signifikan menurunkan keluhan MSDs pada penenun ikat tradisional. Intervensi non-farmakologis ini aman, terjangkau, dan efektif untuk pengendalian MSDs pada pekerja sektor informal.
