Ergonomi sebagai salah satu aspek kesehatan menjadi isu yang hangat dibicarakan oleh para praktisi manufakturing saat ini, sebab manufakturing merupakan salah satu pekerjaan yang menuntut kemampuan fisik. Pekerja bagian final packing dan part supply yang bekerja secara manual (manual handling) di industri manufacturing memiliki risiko tinggi mengalami nyeri punggung bawah. Hal ini jika tidak diantisipasi, dapat mengancam penurunan produktivitas. Penelitian ini bertujuan untuk mengkaji prevalensi nyeri punggung bawah dan faktor risiko yang berhubungan dengan nyeri punggung bawah pada grup final packing dan part supply. Disain Penelitian adalah cross-sectional bersifat deskriptif analitik, berlokasi di PT X Jakarta Timur dengan besar sampel 197 orang (total sampling). Data yang dikumpulkan berasal dari kuesioner, pemeriksaan fisik, observasi lapangan dan wawancara. Untuk menjawab pertanyaan penelitian digunakan uji statistik univariat, bivariat dan multivariat. Hasil penelitian didapatkan Prevalensi nyeri punggung bawah pada pekerja final packing di PT. X adalah 14.2 % dan pada pekerja part supply adalah 10.2 %. uji statistik mendapatkan nyeri punggung bawah berhubungan dengan tingkat risiko punggung (p<0.05; OR = 4.324), kebiasaan olahraga (p<0.05; OR = 4.175), riwayat cidera punggung (p<0.05; OR = 1.451). Hasil uji multivariat menyatakan bahwa karyawan yang memiliki tingkat pajanan punggung kategori tinggi mempunyai peluang 4 kali tidak terkena nyeri punggung bawah dibandingkan dengan karyawan yang memiliki tingkat pajanan punggung kategori sangat tinggi setelah dikontrol variabel olahraga. Rekomendasi untuk perusahaan adalah penambahan alat bantu berupa pallet hidrolik dan jack lift automatic agar postur bungkuk 39° - 72° serta pekerjaan mendorong, menarik dapat dihindari.
Ergonomics as one of the aspects of health become a hotly discussed issue by manufacturing practitioners today, because manufacturing is one job that requires physical abilities. Final packing and parts supply workers work manually (manual handling) in the manufacturing industry has a high risk of experiencing low back pain, if not anticipated, could lead to decreased productivity. Purpose of this study is to assess the prevalence of lower back pain and risk factors associated with low back pain in final packing and parts supply workers. The study design was cross-sectional descriptive analytic, located at PT X East Jakarta with a large sample of 197 people (total sampling). Data collected from questionnaires, physical examination, observation and interviews. To answer the research questions used univariate statistical tests, bivariate and multivariate. The results of research obtained that prevalence of low back pain in final packing workers at PT. X is 14.2% and in part supply workers is 10.2%. Statistical tests have lower back pain associated with the risk level back (p <0.05; OR = 4324), exercise habits (p <0.05; OR = 4175), a history of back injury (p <0.05; OR = 1451). Multivariate test results stating that employees who have high levels of back exposure category had a chance 4 times not affected by low back pain compared with employees who have very high levels of back exposure category after a controlled exercise variables. Recommendations for the company is adding jack lift automatic and hydraulic pallet that bending posture 39 ° - 72 °, pushing and pulling job can be avoided.
The high number of unsafe act prevalence could yield incidents whichcause lose financially to company. The aim of this study is to analyse factors thatcorrelated to unsafe act of workers in preparation and assembling department.This research was conducted in PT X on April to July 2016. These factors dividedinto two categories, personal factors (knowledge, work experience, and educationlevel) and job factors (OHS Information and Supervision). The result shows that72,92% of workers have performed unsafe act in which 61,7% of it is high riskand 38,3% low risk. Moreover, there are siginificant correlations betweeneducation level, knowledge, and availibity of OHS information with unsafe actwhereas education level predominantly contributes to unsafe act after has beencontrolled with other factors. Therefore, company should commit several attemptsto reduce unsafe act on its workers.Keyword : unsafe act, shoes manufacturer, manufactur
