Abstract

In transportation activity, human need a transportation equipment such as car, motorcycle, plane, train, etc. As the number of urban population increase, the number of vehicle increase also, especially for country which has a big number of urban population like Indonesia. The more vehicle and private vehicle owned by urban population cause some effects. The first effect is air pollution that is caused by internal combustion engine gas emission that can give bad effect to human’s health. Second, the increasing consumption of fossil fuel which is one of unrenewable natural resources that we must keep the level of consumption so that we are not run out of fuel before it can be produced again. Third is the increasing of traffic accident which are caused by human error. Therefore, it is important to make a concept about future vehicle which is not use fossil fuel, environmentally friendly and equipped with smart system to prevent accidents. This research aim is to develop a car system concept which can help to solve this problem in Indonesia in 2025 using system engineering methodology from INCOSE which begin with need identification, stakeholder identification (context diagram), concept of operations (ConOps), stakeholder requirement (core functional matrix and QFD) and system architecting. The result of this research is a smart green car system masterplan in Indonesia in 2025.

Abstract

The purpose of this study is  to evaluate the effect of shift work on level of fatigue and  performance of railway controller. Seventeen participants are the railway controller of Bandung Station. Fatigue was measured using subjective questionaire Swedish Occupational Fatigue Inventory (SOFI) and performance was measured using Psychomotor Vigilance Task based on reaction time.  Friedman test and Bonferonni-Dunn test were used to process data. Statistical analysis indicates there was significant difference level of fatigue and human performance between shift work. Fatigue occurs at sleepiness, phsysical discomfort and lack of motivation dimensions, while performance occurs at mean 1/RT, fastest 1/RT and slowest 1/RT (P < 0,10). %. The highest fatigue and the worst performance occurs after night shift. After night shift, the level of fatigue increased about 37% to 162%, meanwhile performance were decreased about 3% to 11%. Although there were significant difference of level fatigue, the average scores are below 1 (score 0-7). This result indicates that the fatigue of controllers  are very low.  Although maybe is not really necessary to redesign shift work system, but working hours on each shift still need to be concerned.

Abstract

Safety climate is an important component of the responsibility of health services and the safety climate survey provides a measure of the safety climate within the organization and identifies opportunities to improve service. Implementation of safety climate in healthcare has been done in many developing countries or developed countries, assessment of safety climate on healthcare by using questionnaires. Low safety culture has a positive contribution to the errors in health services, unsafe therapy, and a variety of other unexpected accidents (medical errors, unsafe therapies, and unintended injuries). Based on this background, this study aims to evaluate the existing safety climate at the regional general hospital in Yogyakarta province, and to know the general picture of the safety climate condition in the hospital. This study was conducted at the emergency department at the hospital with 3 hospitals in Yogyakarta with 84 respondents consisting of nurses, doctors and midwives working in the unit. The results obtained from this study resulted in a valid and reliable questionnaire for each dimension with validity> 0.3 and reliable over 0.6, and also the validity results from questionnaires on other hospitals resulted in consistency of psychometric questionnaires. In this study also shows the index level of each dimension to the hospital. Overview of each hospital on the safety climate can be illustrated based on the level obtained that RSUD II and RSUD I leadership, communication, and also teamwork already has a pretty good level, while RSUD III 3 dimensions that are at level 1 for the dimension of leadership , personal and communication. The personal dimensions of the three hospitals are at level 1 explaining that personal dimensions are still poor in all three hospitals. And also from result of test of Mann Whitney can be seen that there is no difference of perception between doctor and nurse so that equation of perception toward interest of safety climate same between doctor and nurse at RSUD Yogyakarta
