"Traffic accidents are the third largest cause of death according to the World Health Organization. Moreover, driver fatigue is the second largest factor that causes traffic accidents after traffic violations. The purpose of this study is to find out the significance of driver fatigue using physiological, cognitive, and subjective approaches, as well as a comparison of fatigue between male and female drivers. The study involved twelve respondents, which included six male respondents and six female respondents aged 17−25 years old, measured by physiological (blood pressure and heart rate), cognitive (psychomotor vigilance test), and subjective (Karolinska Sleepiness Scale) approaches. The result of this study is that heart rate is the most sensitive variable. However all of the variables in male and female respondents do not have a significant result. There is no big difference in fatigue levels in male and female car drivers. The conclusion of the study is that the approaches could not be a standardized way to measure fatigue for male and female car drivers because of the variation in results."

"The study is aimed at proposing a solution for preventing ship accidents, ship collisions in particular, in Indonesia's busiest ferry crossing lane between Merak on Java Island and Bakauheni on Sumatera Island on the Sunda Strait, which intersects with the Indonesian Archipelagic Sea Lane. The Indonesian Archipelagic Sea Lane is provided by the Government of Indonesia, an archipelagic country, as an international passageway for ships sailing through Indonesian waters from the Indian Ocean to the South China Sea and the Pacific Ocean, by implementing a traffic separation scheme that regulates traffic proceeding in opposite or nearly opposite directions by means of a separation zone or line, traffic lane, etc. The study is motivated by records of fatal accidents that have taken place in the strait, and a portrait of the congested crossing lane is provided. The concept of a traffic separation scheme and its implementation in the Sunda Strait is simulated, with the conclusion that the scheme could minimize potential collisions between ships sailing through the strait. Therefore, it is urgent for the government to implement the scheme."

"This study proposes a method of optimizing the dry storage design for nuclear-spent fuel from the G.A. Siwabessy research reactor at National Nuclear Energy Agency of Indonesia (BATAN). After several years in a spent fuel pool storage (wet storage), nuclear spent fuel is often moved to dry storage. Some advantages of dry storage compared with wet storage are that there is no generation of liquid waste, no need for a complex and expensive purification system, less corrosion concerns and that dry storage is easier to transport if in the future the storage needs to be sent to the another repository or to the final disposal. In both wet and dry storage, the decay heat of spent fuel must be cooled to a safe temperature to prevent cracking of the spent fuel cladding from where hazardous radioactive nuclides could be released and harm humans and the environment. Three optimization scenarios including the thermal safety single-objective, the economic single-objective and the multi-objective optimizations are obtained. The optimum values of temperature and cost for three optimization scenarios are 317.8K (44.7°C) and 11638.1 US$ for the optimized single-objective thermal safety method, 337.1K (64.0°C) and 6345.2 US$ for the optimized single-objective cost method and 325.1K (52.0°C) and 8037.4 US$ for the optimized multi-objective method, respectively."

"In transportation science, the individual’s willingness to pay (WTP) to decrease the number of fatal traffic accidents is one approach to determining the value of road safety (VRS). Such an approach can be performed with the stated preference method, which refers to the concept of preferences contained in microeconomic theory. The concept explains that humans’ behavior is based on their preferences. Researchers have criticized this method because an individual’s preference does not necessarily reflect one’s behavior (B). However, in psychology, this is known as the theory of planned behavior (TPB), which states that human behavior is formed on the basis of intention (I). Until now, VRS determination has lacked an instrument to control the suitability of preference value, which respondents may provide in contrast to their actual behavior; therefore, VRS determination is exposed to potential bias. The purpose of this research is to make intention an instrument for controlling and analyzing the interactions between the preferences and intentions of road users in determining the behavior of paying for vehicle maintenance as a basis for determining VRS. The analytical technique used to analyze the interaction is Structural Equation Modeling (SEM). The research data was obtained through the distribution of a survey form regarding the preferences and intentions of toll road users in Indonesia. The number of samples in this research model were 250 respondents, consisting of 175 men and 75 women who met the criteria for research subjects. Based on the SEM analysis, I had a more significant effect on B than on WTP (63.1% > 35.2%) in correcting the determination of VRS."

The research design used was a cross-sectional with quantitative methods and simple random sampling technique. The results of this study are that the majority of drivers involved in traffic accidents experience injuries and the distribution is dominated by the age group ≤ 35 years, male, highly educated, has a job, has accidents due to negligent behavior and potholes potholes on the road. There is a significant relationship between traffic accidents and human factors, namely education and high speed. Where drivers with higher education are 62.7 times more at risk of experiencing traffic accidents than those with low education and drivers who drive at high speeds are 0.04 times more at risk of experiencing traffic accidents than those who drive at low speeds. There is no significant relationship between traffic accidents and vehicle and environmental factors. The conclusion of this study is that the human factor has an important role in the occurrence of accidents."

"Pengendalian jarak jauh (teleremote operation), yang merupakan engineering control untuk mengurangi tingkat kecelakaan operator Autonomous LHD di PT F, seringkali mengalami productivity loss. Hal tersebut terjadi karena tingginya tingkat kecelakaan yang mengakibatkan kerusakan alat, sehingga total downtime hours pada alat tersebut lebih tinggi dibandingkan dengan operational hours-nya. Penelitian ini memberikan gambaran analisis kecelakaan Autonomous LHD tambang bawah tanah G dari sudut pandang faktor manusia, yaitu dari sisi kegagalan aktif (active failures) dan kegagalan laten (latent failures), untuk mengetahui tindakan tidak aman serta faktor-faktor yang mendasari tingginya tingkat kecelakaan alat. Metode yang digunakan dalam penelitian ini dibuat berdasarkan Human Factor Analysis and Classification System in Mining Industry (HFACS-MI) dengan teknik observasi dan wawancara untuk mengumpulkan data. Hasil penelitian menunjukkan bahwa kegagalan laten (latent failures) lebih banyak ditemukan dibandingkan dengan kegagalan aktif (active failures). Kesalahan berbasis keterampilan (skill-based errors) adalah faktor yang paling sering ditemukan pada kegagalan aktif (active failures), sedangkan faktor lingkungan, kepemimpinan, iklim organisasi, dan faktor luar menjadi faktor yang paling sering ditemukan pada kegagalan laten (latent failures).
