"Research has been done the effect of coffee on sleepiness. Several studies claim that caffeine is proven to overcome sleepiness. However, little is known about the effect of various methods and amounts of coffee intake on a sleep-deprived person. This study compares the effectiveness of one-time and intermittent intake of coffee to overcome driver sleepiness due to partial sleep deprivation. This study used a within-subject experimental design in a driving simulator. There were eight participants, all of whom met certain criteria. The participants’ degree of sleepiness was measured objectively and subjectively. Objectively, the degree of sleepiness was measured based on alpha, beta, and theta brainwaves using an electroencephalograph (EEG); subjectively, this study used the Karolinska Sleepiness Scale (KSS). The participants experienced partial sleep deprivation the night before each experiment. The results of this study support previous studies’ findings that coffee can reduce sleepiness. This study also found differences in the effectiveness of one-time vs. intermittent intake of coffee (sig. value for EEG = 0.025; sig. value for KSS = 0.001). For partially sleep-deprived drivers, one-time coffee intake was found to be more effective in counteracting both objective and subjective sleepiness than intermittent coffee intake."

"An effective and real-time traffic information network is highly important and could contribute to decreasing traffic volume and costs by reducing fuel consumption and saving time for drivers in reaching their destinations. This study provides an extensive analysis regarding the drivers? acceptance levels of the current implementation of the Intelligent Transport System (ITS) in Kuala Lumpur. A proposed model from the literature review based on the known Technology Acceptance Model (TAM) is introduced. The ITS system characteristics, information quality, system quality, and service quality were investigated as external variables. The resulting analysis showed that information quality is the highest influential factor followed by system quality. The results also revealed that service quality had no effect on acceptance levels."

"In this special edition, we have selected 15 papers from the 4th SEANES International Conference on Human Factors and Ergonomics in South-East Asia 2016, which discussed the application of human factors and ergonomics to current local and global needs."

"The aim of this studywas to examine and compare psychological factors influencing car drivers? andmotorcycle riders? speeding intentions (IN), using the Theory of PlannedBehaviour (TPB). The psychological factors modules included Attitude (AT),Subjective Norm (SN) and Perceived Behavioural Control (PBC). These wereemployed to explain speeding intentions in urban road environments. A sample of188 car drivers and 174 motorcycle riders were collected from the twouniversities within Khon Kaen, Thailand. The Structural Equation Model (SEM)was used to examine and explain speeding intentions. The results indicated thatthe TPB could explain 33% and 41% of the variance of intentions by car driversand motorcycle riders, respectively. The most significant psychological factorfor car drivers was determined by attitude (AT), while the speeding intentionof motorcycle riders was attributed to perceived behavioural control (PBC). Theauthorities in Khon Kaen Province should determine safety policies that canimprove these psychological factors, which could have various effects oroutcomes on changing car drivers? and motorcycle riders? speeding intentions.The outcome of this study could help to understand car drivers? and motorcycleriders? speeding intentions in urban road environments and it could be usefulfor development of safety measures."

"The aim of this studywas to examine and compare the psychological factors influencing driverspeeding behavior in 3 cities in Southeast Asia, focusing on developingcounties, using the Theory of Planned Behaviour (TPB). Data was collected from570 respondents in the urban areas of Khon Kaen in Thailand, Vientiane in Laosand Phnom Penh in Cambodia. The psychological factors of TPB include attitude(AT), subjective norm (SN) and perceived behavioral control (PBC). Thesefactors were employed to explain speeding intentions in urban roadenvironments. The Structural Equation Models (SEM) was used to examine andexplain speeding intentions. The results indicated that the TPB could explainthe variance by intentions of drivers in Khon Kaen, Vientiane and Phnom Penh at33%, 46%, and84%, respectively. The most significant of the psychological factors for KhonKaen drivers was determined by AT, while the speeding intentions of Vientianedrivers and Phnom Penh drivers were determined by PBC. From this data, theauthorities of each city should create and implement safety policies that canimprove these psychological factors, which could have a positive effect ondrivers?speeding intentions in urban road environments. The outcome of thisstudy could be useful for understanding the speeding attitudes of drivers inthree different countries and would be beneficial for the development andintroduction of preventative safety measures in these countries as well."

"Rice husk is one of themost abundant biomass wastes in Indonesia. One way to convert it into analternative source of energy is biomass gasification. This is a thermochemicalprocess which converts biomass feedstock into fuel gas or chemical feedstockgas (producer gas). The gasification type which is developed in this study isfixed bed downdraft type due to its low tar content and compatibility inmicroscale implementation. One major problem with the implemented biomassgasification reactor was ruggedness of the partial oxidation process due to theabsence of air in the reactor?s middle section, which consequently affected thepyrolysis zone. Several experiments were conducted previously using coconutshells and rice husks as solid feedstock, where an equivalence ratio (ER) of0.4 was obtained. Therefore, in order to optimize the pyrolysis zone, themodification conducted involves adding a circular air intake into the gasifier.Experiments were conducted in a pyrolysis temperature range of 300?700oCwith ER variation of 0.19, 0.24, 0.27 and 0.31. The results show that a goodquality producer gas is produced at an ER value of 0.24. This value shows apromising result because the ER value of biomass gasification standard is 0.25."

"AbstrakPerbedaan pola penggunaan internet berhubungan erat dengan distribusi kekuasaan yang tidak setara dalam keluarga: antara suami dan istri, antara anak perempuan dan laki-laki. Teknologi internet yang mengalami domestifikasi ini berintegrasi dengan pembagian peran gender dalam keluarga dan merembes dalam praktik sosialisasi mengenai perilaku yang berkaitan dengan penggunaan komputer dan internet. Pola penggunaan komputer yang berbeda antara ayah dan ibu, melemahkan ketertarikan dan minat anak perempuan terhadap komputer dan internet (technophobia). Akan tetapi, dalam kajian Blogger Indonesia dengan menggunakan IES, dalam tulisan ini, menunjukkan bahwa perempuan dan laki-laki memiliki sikap yang sama terhadap internet apabila perempuan diberi akses dan waktu yang sama seperti laki-laki"

"ABSTRAKPenelitian korelasional ini dilakukan untuk mendapatkan gambaran mengenai hubungan antara computer self-efficacy (CSE) dan penggunaan komputer oleh guru sekolah dasar. CSE didefinisikan sebagai keyakinan seseorang mengenai kapabilitasnya untuk menggunakan komputer (Compeau & Higgins, 1995), sedangkan penggunaan komputer didefinisikan sebagai frekuensi guru menggunakan komputer dalam bentuk preparation, professional e-mail, delivering instruction, accommodation, dan grading (Babell, Russell, & O?Dwyer, 2004). CSE diukur menggunakan alat ukur Computer Self-Efficacy milik Compeau & Higgins (1995) dan penggunaan komputer menggunakan alat ukur Teachers? Technology Use milik Babell, Russell, & O?Dwyer (2004). Data didapat dari 164 orang partisipan guru sekolah dasar di Jakarta, Bogor, dan Bekasi. Hasil penelitian menunjukkan terdapat hubungan positif signifikan antara CSE dan penggunaan komputer pada guru sekolah dasar (r = 0,486, p = 0,000, L.o.S. 0,01). Berdasar pada hasil penelitian, peneliti menyarankan pihak guru dan sekolah untuk mengupayakan peningkatan CSE guna meningkatkan penggunaan komputernya.

ABSTRACTThis correlational study was conducted to demonstrate the relationship between computer self-efficacy (CSE) and elementary school teachers? use of computer. CSE is defined as a judgement of one?s capability to use a computer (Compeau & Higgins, 1995) and teachers? use of computer is defined as the frequency of teachers? using computer in the form of preparation, professional e-mail, delivering instruction, accommodation, and grading (Babell, Russell, & O?Dwyer, 2004). CSE was measured by Computer Self-Efficacy Scale (Compeau & Higgins, 1995) and teachers? use of computer was measured by Teachers? Technology Use Scale (Babell, Russell, & O?Dwyer, 2004). Data was collected from 164 elementary school teachers in Jakarta, Bogor, and Bekasi. The main result shows that there is a significant positive correlation between computer self-efficacy and teachers? use of computer on elementary school teachers (r = 0,486, p = 0,000, L.o.S. 0,01). Based on the study result, it is suggested for teachers and schools to work on improving the CSE in order to increase the use of computers.This correlational study was conducted to demonstrate the relationship between computer self-efficacy (CSE) and elementary school teachers? use of computer.
