Human error has played a critical role in the events precipitating the road accidents. Such accidents can be predicted and prevented by risk assessment, in particular assessing the human contribution to risk. As part of the Human Reliability Assessment (HRA) process, it is usually necessary not only to define what human errors can occur, but how often they will occur. Lack of understanding of the failure distribution characteristics of drivers on roads at any given time is a factor impeding the development of human reliability assessment and prediction of road accidents in order to take best proactive measures. The authors developed the complete investigation methodology for crash data collection. Furthermore, they have experimentally tested the proposed predictive behavioral characteristics of drivers in light of their instantaneous error rate over the course of driving period to assist processing and analysis of data collection as part of risk assessment. The findings of this research can assist road safety authorities to collect the necessary data, to better understand the behavioral characteristics of drivers on roads, to make more accurate risk assessments and finally to come up with right preventive measures.

Human reliability assessment is becoming increasingly important in risk assessment in all industrial systems. All methods for human reliability assessment are used to estimate human error probabilities, which is a measure of human reliability. Human error assessment is certainly a challenge fo r all the experts involved in risk assessment today. In Serbia, this issue has not received proper attention yet. Therefore, this paper presents the case study which confirmed that the usage of Absolute Probability Judgement for proper human reliability assessment. This approach was used in a case study of the Electric Power Company in Serbia (hereinafter EPCS) for the purpose of the analysis accident of a repair intervention on a 10/0.4 kV steel lattice tower “Nova Kolonija” (jurisdiction of EPCS, Veliki Trnovac, ED “Jugoistok”, Nis, Serbia). The case study performed at the EPCS has confirmed that the conventional APJ approach is not only highly applicable for quantification of human errors, but also comprehensive and simple to use in risk assessment of complex systems.

Nowadays, the human error is usually identified as the conclusive cause of investigations in road accidents. The human although is the person in control of vehicle until the moment of crash but it has to be understood that the human is under continued impact by various factors including road environment, vehicle and human's state, abilities and conduct. The current advances in design of vehicle and roads have been intended to provide drivers with extra comfort with less physical and mental efforts, whereas the fatigue imposed on driver is just being transformed from over-load fatigue to under-load fatigue and boredom. A representational model to illustrate the relationships between design and condition of vehicle and road as well as driver's condition and state on fatigue and the human error leading to accidents has been developed. Thereafter, the stochastic mathematical models based on time-dependent failure rates were developed to make prediction on the road transportation reliability and failure probabilities due to each cause (vehicle, road environment, human due to fatigue, and human due to non fatigue factors). Furthermore, the supportive assessment methodology and models to assess and predict the failure rates of driver due to each category of causes were developed and proposed.

The authors have recently developed a microworld, a simplified process control simulator, to simulate a nuclear power plant. The microworld provides an environment that can be readily manipulated to gather data using a range of participants, from students to fully qualified operators. Because the microworld represents a simplified domain, it is possible to have more precise experimental control compared with the complex and confounding environment afforded by a full-scope simulator. In this paper, we discuss collecting human reliability data from a microworld. We review the generalizability of human error data from the microworld compared to other data sources like full-scope simulator studies and compare advantages and disadvantages of microworld simulator studies to support human reliability data collection needs.

APPLICATION OF HIRA AND SPAR-H METHOD TO CONTROLWORK ACCIDENTCINDY BEAUTY SIJABAT* DAN SUNDAY NOYAIndustrial Engineering Study Program, Faculty of Science and Technology, Universitas Ma ChungVilla Puncak Tidar N-01, Malang, East Java 65151E-mail: [email protected] kecelakaan di industri merupakan salah satu penyebab gangguan atau penghentian kegiatanindustri. Kecelakaan kerja adalah sesuatu yang harus dihindari karena akan mengakibatkan kerugian bagiperusahaan. PT “X” adalah industri tembakau yang memiliki tingkat kecelakaan kerja cukup tinggi, olehkarena itu diperlukan tindakan untuk menghindari atau meminimalkan terjadinya kecelakaan. HazardIdentification and Risk Analysis (HIRA) adalah metode yang bertujuan untuk mengidentifikasi semuajenis bahaya yang terkandung dalam kegiatan kerja. Sedangkan metode Standardized Plant AnalysisRisk Human Reliability Assessment (SPAR-H) adalah sebuah metode yang bertujuan untuk mengetahuikemungkinan terjadinya kesalahan manusia ketika melakukan aktivitas kerja. Dari penelitian yang telahdilakukan, disimpulkan bahwa terjadinya kecelakaan di tempat kerja PT “X” disebabkan oleh adanyakondisi lingkungan dan tindakan pekerja yang tidak aman serta ketidaksesuaian dengan undang-undangK3. PT “X” perlu melakukan beberapa tindakan korektif sehingga kecelakaan dapat diminimalkan. Dalamstudi tersebut, PT “X” perlu membuat perbaikan melalui tindakan administrasi dan penggunaan peralatanperlindungan.Kata kunci: kecelakaan kerja, HIRA, SPAR-HABSTRACTThe accident occurred in industry is one of the causes of work disruption or cessation. Work accidentshould be avoided because of causing risk for company. PT “X” is a tobacco company which has a high levelof work accident. Therefore, it is necessary to establish a particular effort in order to prevent and reduce theaccident. Hazard Identification and Risk Analysis (HIRA) is the method aims to identify any risk typesincluded in the work operation. Where as Standardized Plant Analysis Risk Human Reliability Assessment(SPAR-H) is the method aims to find out the possibility of human error occurrence in the work operations.Based on the research conducted, it can be concluded that the accident occurred in PT. “X” is caused byenvironmental condition and insecure workers’ action, and inappropriateness with HSE procedures. PT“X” should enroll some corrective actions so the accident can be reduced. In this study, PT “X” should createimprovement through administrative action and the use of safety equipment.Key words: work accident, HIRA, SPAR-H
