Abstract

Introduction: The need of desks and chairs at school which appropriate with student’s anthropometry are very important. Desks and chairs which not suit with student’s anthropometry will lead to fatigue. At Kabupaten Gresik, the provision of desks and chairs which suit with student’s anthropometry still less in number. This study was aimed to provide recomendation for an ergonomic desk and chair prototype to improve seating position on senior high school students at Kabupaten Gresik. Method: This was preexperiment research with one group pre post test design. Research subjects were students at SMAN 1 Menganti and SMAN 1 Cerme, Kabupaten Gresik, 139 students were involved. Result: The recomendation of ergonomic desks and chairs specifi cation according to student’s anthropometry were: 1) Prototypechair N, length = 48 cm, wide = 43 cm, cushion base’s height from floor surfaces = 47 cm, bag keeper’s height from floor surfaces =3cm, bag keeper’s wide= 43 cm, bag keeper’s length = 47 cm, cushion’s wide = 41 cm, cushion’s length = 46cm, handrest’s height = 22 cm, handrest’s length = 30 cm, backrest’s height = 38 cm, backrest’s wide = 43 cm, cushion’s foam thickness = 4 cm, backrest’s foam thickness = 4 cm; 2) Prototype desk N, length = 50 cm, wide = 66 cm, back section’s height = 85 cm, front section’s height = 75 cm, footrest from fl oor surfaces = 10 cm, drawer’s height = 10cm, front bamper’s height = 40 cm, and table’s angle = 10o. Discussion: An ergonomic desks and chairs are very important for students at school, it will help teaching learning process run well and comfortable. The measurement of desk and chair must be reviewed after fi ve years, because of student’s anthropometric development. So then students will feel no fatigue.Keywords: ergonomy, senior high school student’s seating position

Abstract

Latar belakang: Peran tenaga manusia sampai saat ini merupakan hal utama dan paling penting dalam proses produksi, tidak sedikit proses produksi yang masih menggunakan peralatan manual yang melibatkan peran manusia, atau lebih dikenal dengan pekerjaan manual. Padahal manusia memiliki keterbatasan khususnya dari segi fisik sehingga dapat menimbulkan kelelahan. Ditemukan beberapa persoalan sebagian besar cara kerja tidak dilakukan secara tidak ergonomis seperti posisi kerja jongkok, teknik pengangkatan beban yang keliru, sifat pekerjaan yang cepat karena pekerja di tuntut untuk mengejar target pekerja berisiko mengalami kecelakaan kerja. Penelitian ini bertujuan untuk adalah untuk mengetahui pengaruh usia, masa kerja, status gizi, durasi tidur, kebiasaan merokok sikap kerja dan beban kerja terhadap kelelahan kerja pada pekerja pabrik unit produksi “SP” alumunium Kota Yogyakarta.Metode: Penelitian ini merupakan penelitian observasional analitik dengan menggunakan studi cross sectional. Populasi berjumlah 153 orang, sampel diambil berdasarkan total sampling pada unit produksi  pabrik “SP” Alumunium. Data dianalisis dengan menggunakan analisis univariat, bivariat, dan multivariat.Hasil: Dari hasil analisis yang dilakukan, usia dengan kelelahan kerja p value = 0,040 (p<0,05, OR=2,52), , masa kerja dengan kelelahan kerja p value = 0,047 (p<0,05, OR=2,36), status gizi dengan kelelahan p value = 0,590 (p<0,05, OR=1,27), durasi tidur dengan kelelahan p value = 0,045 (p<0,05, OR= 0,045), kebiasaan merokok dengan kelelahan p value = 0,268 (p<0,05, OR= 1,61), sikap kerja dengan kelelahan p value = 0,045 (p<0,05, OR=2,4), beban kerja dengan kelelahan p value = 0,013 (p<0,05, OR=3,18). Analisis multivariat menggunakan uji regresi logistik mengungkapkan variabel yang paling mempengaruhi diantara semua variabel yaitu sikap kerja p value=0,022 dengan tingkat risiko 3 kali lebih besar pada sikap kerja kategori berat dan usia p value= 0,019 dengan tingkat risiko 3 kali lebih besar pada orang usia >35 tahun.Kesimpulan: Berdasarkan hasil diatas bahwa variabel sikap kerja, beban kerja, usia, masa kerja, durasi tidur mempengaruhi kelelahan kerja sedangkan variabel status gizi dan kebiasaan merokok tidak mempunyai pengaruh terhadap kelelahan kerja.

Abstract

Air toluene exposure and peripheral neuropathy cases in offset printingPurposeThe purpose of this paper was to determine the relationship between toluene exposure in the air at each workstation in offset printing with the incidence of peripheral neuropathy.MethodsA cross-sectional study was conducted involving total sampling of the offset printing workers who met the criteria. ResultsThe study found that there was no correlation between toluene exposure in the air with the incidence of peripheral neuropathy in offset printing workers in Sleman. Based on the ENMG test, there were only 21.42% workers diagnosed with peripheral neuropathy from 14 workers diagnosed with neuropathy; and it can be ascertained that these were not caused by toluene exposure in the air. ConclusionThere was no correlation between toluene exposure in the air in offset printing with peripheral neuropathy for this study. Weight, length of work, and education were the factors of toluene exposure found in this study. Workers need to pay attention to the limits of the length of exposure.
