Usaha Kecil Menengah (UKM) merupakan sumber ekonomi potensial di masyarakat yang mampumenggerakkan roda ekonomi sampai pada tataran masyarakat bawah. Berbagai keunggulan yang ada di UKMterdapat juga hal-hal yang perlu ditingkatkan salah satunya adalah metode kerja pekerja. UKM Kerupuk Ikandan UKM Raos yang memproduksi kerupuk juga merupakan UKM yang perlu mendapatkan perbaikan padasistem kerjanya. Standard Nordic Questionnaire (SNQ) merupakan alat yang dapat mengetahui bagian-bagianotot yang mengalami keluhan dengan tingkat keluhan mulai dari Tidak Sakit (TS), agak sakit (AS), Sakit (S) danSangat Sakit. Perbaikan diawali dengan mengidentifikasi keluhan operator melalui penyebaran kuisionerStandard Nordic Questionnaire (SNQ). Hasil dari identifikasi ini diketahui para operator mengalami keluhanMusculoskeletal Disorders (MSDs). Kondisi ini terjadi dikarenakan seringnya pekerja bekerja dengan posturkerja yang janggal, yaitu postur membungkuk, duduk dan jongkok. Postur kerja ini memicu timbulnya gangguanpada otot, kesemutan, pegal, dan sakit pada sendi sehingga meninbulkan keluhan-keluhan operator. Keadaan inimengindikasikan bahwa aktivitas tersebut tergolong kedalam kategori berbahaya dan dapat menyebabkan risikoMSDs. Melihat kondisi di UKM ini dilakukanlah penelitian untuk mengetahui keluhan yang dirasakan pekerjadan selanjutnya dilakukan analisis dan perbaikan aktivitas serta postur kerja. Hal ini sebagai upaya untukmengurangi MSDs dan keluhan-keluhan yang dirasakan oleh pekerja selama bekerja.
