Abstract
Low back pain has become a central issue of physiological health. Almost all the discussion of musculoskeletal complaints places more emphasis on the need to pay attention to the importance of health in the lower back. One of the causes of workers' complaints on the lower back is a less natural posture when on the move. The impact that is most easily observed as a result of the emergence of low back pain is the emergence of fatigue and decreased work motivation. Observation of the impact of low back pain on workers was examined using the same subject design. The subject are 11 people who work as wood carving artists. In period 1 the subjects worked in conventional working conditions, while in period 2 the subjects were given treatment, namely anticipation of complaints of low back pain, working in ergo-anthropometric working conditions, ie given ergonomic work tables and chairs with additional nutrition intake, active rest and work uniform. The fatigue variable was measured using a 30 items rating scale questionnaire and crafters' motivation was measured by a questionnaire on 4 Likert scales. Data analysis begins with descriptive analysis and normality test data with ShapiroWilk. Data with normal distribution are used t-paired analysis and data with abnormal distribution use Wilcoxon test. In this study it was found that ergo-anthropometric working conditions can reduce fatigue by 27.34% and increase work motivation by 20.39%. It can be concluded that efforts to anticipate complaints of low back pain can reduce fatigue and maintain work motivation of carving craftsmen.

Summary
Karakteristik subjek adalah data bawaan yang sudah dimiliki oleh masing-masing subjek. Mengobrol sesama seniman sambil bekerja atau bernyanyi-nyanyi kecil selama aktivitas menandakan juga para seniman telah berada pada tingkat matang dan tanpa beban. Penurunan denyut nadi istirahat menandakan bahwa subjek berada pada suasana hati yang rileks saat pengukuran di periode 2. Untuk mengetahui kondisi kesehatan subjek, telah diadakan pemeriksaan kesehatan ringan dengan indikator kandungan gula darah, tekanan darah dan denyut nadi serta ciri-ciri fisik lainnya. Sebagaimana yang sudah umum diketahui, jika sebuah perlakuan menghasilkan sebuah hasil yang berbeda secara signifikan pada pengukuran dengan kondisi lingkungan yang berbeda, maka sesungguhnya hasil penelitian belum berlaku final karena besarnya pengaruh lingkungan terhadap kondisi subjek belum sepenuhnya diketahui (Pandit, dkk., 2013). Pada penelitian ini beberapa data yang menunjukkan kondisi lingkungan, seperti kecepatan angin, intensitas cahaya, suhu basah dan suhu kering, temperatur radian, kebisingan, kelembaban dan indeks wet bult globe temperature (WBGT), ditunjukkan pada Tabel 2.
