Professional drivers with monotonous work characteristics with long mileage andlong driving duration even past supposed rest periods so as to conflict with naturalcircadian rhythms, as well as continuous driver seats along the way may cause driverfatigue. This condition is exacerbated by the lack of quantity of sleep as well as poor sleepquality and sleep hygiene drivers. The driver at PT. X has the task of distributing fuelusing a tank with a capacity of 16,000 L with an average mileage taken over 300 km andthe duration of travel more than 8 hours. These various conditions can cause fatigue inthe driver of PT. X. Analytical research with cross-sectional design is aimed to analyzethe relationship between the quantity of sleep, sleep quality, sleep hygiene, drivingduration and mileage with driver truckload fatigue at PT. X. Research conducted inFebruary to June 2018 uses several data collection tools, namely: questionnaires,tensimeter, oximeter and smartwatch fitbit tool. Data analysis used mean difference testand chi square test. From the different test mean known that there is fatigue work on thedriver PT. X after driving. From chi square test obtained that there is relation betweenquantity of sleep, sleep quality, sleep hygiene and mileage with fatigue of driver of goodscargo at PT. X.
Fatigue is one of the causes of the accident to the driver. Many drivers who consume energydrinks to reduce fatigue. This study aims to determine the effect of the consumption of energydrinks on the driver's fatigue level PT X Jakarta. This study uses an analytical study design withcross sectional approach. Of the 54 drivers there were 40 drivers who consume energy drinkswith a p-value = 0.060 indicates that there is no relationship with the driver's fatigue events thatdo not consume energy drinks with a driver who drinks energy drinks consumption.Keywords: Fatigue, Driver, Energy Drink.

Driver fatigue is one of the main cause of road accident. This study aimed todetermine the correlation between petroleum truck driver fatigue with the risk factorsuch as age, BMI (body mass indeks), driving hours, working period, rest time,commuting time, work shift, and sleep hours of petroleum truck drivers. This studywas conducted in June 2016 at PT. X Depot TBBM Plumpang Jakarta. Total sampleof this study are 123 drivers. This research is based on quantitative observationalstudies using cross-sectional approach. Measurement of fatigue using subjectivesymptoms tes based on Industrial Fatigue Research Committe (IFRC). The resultsshow that 60,1% drivers experienced mild fatigue, while 39,1% drivers experiencedmedium fatigue. The result of chi-square calculation did not show any statisticallysignificant association between risk factor with driver fatigue, although otherstatistic test such as t-test and correlation test significantly show that driving hoursand working period show positive relation with the fatigue score.

Fatigue is the major cause of accident involving heavy vehicle drivers, one of them is truck drivers. Therefore, the purpose of this research is to identify fatigue hazard and analyze fatigue risk level, so that the appropriate control can be determined. Variables studied include length of work, work shift, work environment, workload, rest time, physical condition, sleep quantity, sleep disturbance, and stress. Identification of fatigue hazard and analysis of fatigue risk level conducted to each variable. Identification of fatigue hazard was conducted by observation and interview with the drivers and the operator. Analysis of fatigue risk level was conducted by qualitative method and calculated with crossing consequences level and likelihood level.
Salah satu bentuk hazard adalah pola kerja/istirahat dan waktu kerja. Diklasifikasikan sebagai salah satu jenis hazard karena pola kerja berpotensi menimbulkan gangguan irama kerja dan istirahat pada manusia terutama pada pekerja shift malam. Sebagai salah satu akibat negatif dari pola kerja terutama pola shift, kelelahan kerja merupakan keluhan umum pada populasi pekerja. Hampir 20% dari populasi pekerja melaporkan gejala yang termasuk dalam kelelahan kerja . Sedangkan kelelahan kerja sendiri mempunyai efek negatif pada safety, kesehatan dan pembiayaan. Tujuan penelitian ini adalah untuk mengetahui tingkat kelelahan pada karyawan perusahaan migas X Kalimantan Timur dan hubungan antara kelelahan dengan pola kerja, umur, lama bekerja, jenis pekerjaan, jam kerja, indeks massa tubuh dan kondisi kesehatan untuk dapat diambil langkah - langkah dan upaya mitigasi. Desain penelitian ini adalah penelitian cross sectional dan pengukuran kelelahan dilakukan dengan menggunakan 2 metode yaitu subjective feeling fatigue dengan menggunakan kuesioner Fatigue Assesment Scale (FAS) dan alat pengukur kecepatan reaksi reaction time. Hasil penelitian menunjukkan bahwa prosentase kelelahan bervariasi antara 33% sampai dengan 88%. Hasil penelitian juga menunjukkan bahwa jam kerja adalah faktor yang berhubungan dengan kelelahan sedangkan faktor pola kerja, umur, lama bekerja, jenis pekerjaan, indeks massa tubuh dan kondisi kesehatan tidak berhubungan. Analisis multivariat pada menunjukkan bahwa faktor jenis kerja, usia dan jam kerja adalah faktor - faktor yang dominan berpeluang mempengaruhi kelelahan. Perlunya dilakukan penelitian yang lebih mendalam mengenai kelelahan kerja dengan mempertimbangkan faktor independen lain seperti faktor lingkungan dan tanggung jawab. Pemanfaatan waktu istirahat dengan baik, pengaturan waktu kerja, pengelolaan lingkungan kerja, program olah raga dan pemeriksaan kesehatan secara berkala merupakan usaha - usaha yang dapat dilakukan untuk penegelolaan keleleahan kerja di lokasi kerja.
One type of hazard is work/ rest pattern. It is classified into one type of hazard since the work pattern has potential to disturb working and rest rhythm for human being especially for night shift workers. As one of negative impacts of working pattern especially shifts work, fatigue is general complaint from workers population. Almost 20% of the worker`s population reporting fatigue symptom. Fatigue itself has negative effects on safety, health and cost. The purposes of this research are in order to know fatigue condition of employees who work at oil and gas company X East Kalimantan and the relationship between fatigue and working pattern, age, working tenure, working type, working hour, body mass index and illness for taking necessary and mitigation actions. The research design is cross sectional and fatigue measurement using 2 methods i.e. measuring subjective feeling fatigue with Fatigue Assessment Scale (FAS) questionnaire and measuring reaction time. The result showed that percentage of worker with fatigue is varying from 33% up to 88%. Working hour is the only independent factor which has relationship with fatigue among other factors such as working pattern, age, working tenure, working type, body mass index and illness. Multivariate analysis showed that working type, age and working hour are dominant factors which are contributing to fatigue. Conduct further research on fatigue using other independent factors such as environment and responsibility. Optimize rest and break time, working time arrangement, working environment management, fitness and sport program and annual medical program are mitigation programs for fatigue management on site.
