The processing of smoked fish that is carried out by the XIII Koto Kampar community is still relatively simple, the weaknesses caused by traditional fish smoked include the appearance of being less attractive (partially charred) difficult temperature control and polluting the air. In this research, a fish smoking system was designed using and oven model with a separate combustion chamber, the smoke is flowed through a pipe equipped with a filter and piping design to circulate the smoke evenly to the smoke cabinet. Retrieval of test data in the form of; Efficiency of smoking time by measuring temperature on each shelf and air humidity (RH) in the fumigation chamber, taking proximate content test data to determine moisture, ash, protein and fat content. Temperature testing for 480 minutes while maintaining the temperature between 30-40 ◦C. Humidity at 55% during the curing process and moisture content from 65-48%.

Workers who work the night shift have a tendency to get stressed and subsequently suffer from fatigue as a clinical symptom. This study aims to formulate an effective strategy of policy to emphasize the reduction in the effect of applying work shifts to the risk of fatigue. Based on the results that the average amount of reactive time for morning shift workers is 0.97 seconds, while for night shift workers is 1.18 seconds. The average amount of blood systole pressure for morning shift workers is 119.22 cm Hg, while for night shift workers is Hg 127.61 cm. The average amount of blood diastole pressure for morning shift workers was 77.44 cm Hg, while for night shift workers it was 82.16 cm Hg. The average heart rate for morning shift workers was 73.93, while for night shift workers it was 76.18. Based on the results of a statistical examination that there is a significant effect on fatigue (p = 0,000), it means that there is a significant relationship between work shifts and stress-causing fatigue (p = 0,000). Therefore, as the proposal of this study and to anticipate the reduction in fatigue, it is important to make improvements and evaluations about the rules of work shifts in a company so that night shift workers can work in safe conditions and rest well after work

This study discusses the problem of decision making to choose the best employee alternatives. To solve this problem Fuzzy Analytical Hierarchy Process is used, the development of conventional Analytical Hierarchy Process which is designed to deal with problems with more subjective criteria. The choice of the best employees with the Fuzzy Analytical Hierarchy Process shows that the subjectivity of the criteria is of greater concern compared to using the conventional Analytical Hierarchy Process.

This research was conducted in November to December 2019 at PT. Sejahtera Mandiri St. Raya Pekanbaru Bangkinang Km 16, Riau Province. This research aims to find out the layout of plant facilities and Material Handling of activities input until it becomes ouput. This activity is carried out by collecting data throug observation, interviews, to take several documents such as photographs. With these data are analyzed in terms of the layot of plant facilities and Material Handling at PT. Sejahtera Mandiri so it produces some proposed designs or proposed opinions related to the layout of plant facilities and Material Handling. The result of this study indicate that the layout of factory facilities and Material Handling PT Sejahtera Mandiri has been optimized according to factory area considerations but there are some input points, such as the allocation of several work stations and realted proposals Material Handling of one work station and other work station that aim can minimize production costs and production time.
