Some risks which influence the life of labours should be anticipated by the way of synchronizing among the labours, working processes and environments with ergonomic approaches. The fatigue is a mechanism process of body protection, so that the body will be prevented fromthe fatigue and recoverable after having a rest. The labours which work at night shift have a tendency to get the stress and next will be suffering from fatigue as the clinic phenomena. This research is purposed to formulate the effective strategy of policy for stressing the decrease of the influence of applying the work shift into the risk of fatigue. This is a cross sectional research with its research method is analytic survey. The sample which is used is 30 labours, working in morning and night shifts. The research variables are consist reaction time in the form of fatigue level, blood pressure, heart pulse, physical and mental stress of a people. The instruments or testers used to take data of labourâ€™s reactive time are the Whole Body Reaction is for time, the tension meter is for blood tension, the fingers hand for heart pulse, and the questioner is for physical and mental stress. The data which are obtained for the variable of reactive time, blood pressure, and heart pulse are numerical and analysed by using t test, while the data which are obtained for the variable of physical and mental stress are not numerical and analysed by using chi square test. Based on the result that the total of averages of the reactive time for morning shift labours are 0,97 second, while for the night shift labours are 1.18 second. The total of averages of systole blood pressure for morning shift labours are 119.22 cm Hg, while for the night shift labours are 127.61cm Hg. The total of averages of diastole blood pressure for morning shift labours are 77.44 cm Hg, while for the night shift labours are 82.16 cm Hg. The total of averages of heart pulse for morning shift labours are 73.93, while for the night shift labours are 76.18. Based on the result of the statistical examination that there is a significant influence in to the fatigue (p=0,000), it means that there is a significant relation between working shift and fatigue caused of the stress (p=0,000). Therefore, as the recomendationof this research and in order to anticipate the decreasing of fatigue, it is important to do the improvement and the evaluation about the rules of work shift in a company, so that the night shift labours can work in the safe condition and take the rest well after working.

Nanocrystalline of Barium Hexaferrite (BaFe12O19) powders have been synthesized using the sol gel auto combustion method. The ferrite precursors were obtained from aqueous mixtures of Barium nitrate and Ferric nitrate by auto combustion reaction from gel point. These precursors were sintered at different temperatures ranging from 700 to 1000oC for constant calcinations time 2,5 h in a static air atmosphere. Effects of Fe3+/Ba2+ mol ratios and sintering temperatures on the microstructure and magnetic properties were systematically studied. The powders formed were investigated using X-ray diffraction (XRD), scanning electron microscope (SEM) and VSM. The results obtained showed that the phase BaFe12O19 powders were achieved by the Fe3+/Ba2+ mole ratio from the stoichiometric value 11, 11.5 and 12 at temperature 950OC. With increasing of temperature sintering, coercivity and magnetization value tends to rising. The maximum saturation magnetization (66.16 emu/g) was achieved at the Fe3+/Ba2+ mole ratio to 11.5 and the sintering temperature 950OC. The maximum coercivity value 3542 Oe achieved at mole ratio sample 12 with sintering temperature 950OC. Maximum saturation 6616 emu/g achieved at mole ratio sample 115 with the same temperature.
