Abstract

The most dominant factor causing traffic accidents is the human factor, such as sleepy driver. Other distraction factors that can cause traffic accidents is the use of cell phones. This experiment was conducted to prove this by using a driving simulator. The experimental design will be divided into 3 stages, starting from stage 1 (easy), stage 2 (moderate), and stage 3 (difficult). This study was measured using subjective measurements using the Karolinska Sleepiness Scale (KSS) method, and objective measurement by measuring heart rate (bpm), and recording driving error data. The data collected will be processed using the Two Way Anova method to find the influencing factors. The results of the test based on subjective data there are differences in stage 3 where respondents are more awake. Meanwhile, based on objective data on heart rate measurements, there are differences between the pretest stage with stages 2 and 3. If based on driving errors, stage 1 is different from stages 2 and 3. Based on the results of data processing, it is obtained that road conditions that have a high density can increase driver alertness, then the use of mobile phones has a major influence on the occurrence of driving errors.

Abstract

Stroke could cause paralysis and reduced body function. In an effort to self-mobilize, a stroke patient needs a wheelchair. Even though the existing wheelchairs have undergone significant development, both in terms of design and technology, the function of these wheelchairs is still limited, to assist users in carrying out their daily activities and there is no wheelchair that functions as a wheelchair. therapy tool. One way to recover from a stroke and help prevent further disability is therapy, both medical therapy and alternative therapy. Therefore, in this study a wheelchair was designed to function as a therapeutic tool by making circular movements carried out by the arms, hands and legs as well as movements away from and towards the chest carried by the arms and hands so that the muscles could be strengthened, thus helping the recovery process from stroke, especially those that attack the hands and feet of stroke sufferers. The method used in the design is design thinking that focuses on humans, knowing user needs, and innovating according to user needs. The design thinking process consists of 5 stages: empathize, define, ideate, prototype, and test. In its design, wheelchairs are also made to consider ease of installation and use.
