Abstract

Various health problems are known from shift works. PT. Toyota Motor Manufacturing Indonesia (TMMIN) as a car manufacturing in Indonesia is a large industry that applies a shift work system for the workers. This study aims to see the relationship between shift work system in the Stamping Division of PT. TMMIN. The measurement works by using the reaction time method on the worker the shift (shift I/morning and shift II/night) and non-shift during the workday flash. Based on the average measurement of reaction time for the shift workers I was 284.79 milliseconds and shift worker II was 307.76 milliseconds. The risk of reaction time increase was 3.222 times due to shift works compared to non-shift workers. Based on the value of reaction time, shift workers in PT. TMMIN recommends a repair per shift after work on the eighth day for shift I and twelfth day for shift II.

Abstract

Aim: This study was aimed to analyze the potential of water sources in the Ciberang River to support drinking water supply system of Banten Province. Methodology and results: The method use to analyze the potential of Ciberang river is a hydrological statistical analysis. The results of the hydrological statistical analysis show that the water resources of the Ciberang River are not sufficient to meet domestic and industrial water needs in Banten Province. Domestic and industrial water demand in Banten Province in 2025 is estimated at 14.64 m3/s and 10.46 m3/s, respectively, while the mainstay discharge with the return period of 10 and 20 year for all durations does not meet these water needs. The mainstay discharge of the Ciberang River with a 10-year return period of 1, 2, 7, 15 and 30 day respectively was 0.08 m3/s, 0.1 m3/s, 0.19 m3/s, 0.36 m3/s, and 0.87 m3/s. The mainstays of the 20-year return period of 1,2,7,15 and 30 day respectively are 0.04 m3/s, 0.06 m3/s, 0.11 m3/s, 0.23 m3/s and 0.59 m3/s. Conclusion, significance, and impact study: Based on this, it is necessary to conserve water resources to increase the main flow of the Ciberang River. One of the strategic policies to increase the river's mainstay discharge is constructing the reservoir.
