The National Transportation Safety Board, driver fatigue in the United States considered to bet he most important road safety factor because accounts for approximately 100.000 heavy vehicle accidents and 1.500 fatalities per year. Fatigue is a factor in an estimated 30 to 40 percent of heavy vehicle accidents and 15 percent of fatal. Fatigue causes a loss of alertness in a driver. Which is slower reaction time, decreased skill levels, a driver’s ability to concentrate and make critical decisions is reduced, it takes longer to interpret and understand a traffic situation. It is a significant problem in the road transport sector in terms of the health and quality of life of drivers, as well as in the potential for accidents. The purpose of this study is to identify the difference of the average of work fatigue between APTB bus driver and Transjakarta bus coridor 8 on 2017. Cross Sectional methodology was chosen in this study. The population of this study were 30 respondents APTB bus d...

Abstrak: Penelitian bertujuan untuk menguji validitas SUTRA dalam memodelkan sebaran konduktivitas listrik air tanah aliran tunak yang terkontaminasi limbah. Untuk keperluan pengujian, dibuat model fisik yang diinjeksi secara konstan dengan limbah. Konduktivitas listrik pada masing-ntasing node diukur dengan konduktivitimeter. flail dari model fisik ini dan hasil perhitungan dengan menggunakan SUTRA diplot dengan surfer dan dibandingkan. Diperoleh bahwa SUTRA cukup valid digunakan untuk memodelkan sebaran konduktivitas listrik air tanah aliran tunak yang terkontaminasi limbah.
