Abstract

Work fatigue is an important aspect and is very influential in determining the level of accidents, especially motorbike accidents. According to WHO, almost 30% of all deaths due to road accidents involve two- and three-wheel­ed motorized vehicles, such as motorbikes, mopeds, scooters and electric bicycles (e-bikes), and the number continues to increase. Motor­cycles dominate road deaths in many low- and middle-income countries, where nine out of ten traffic accident deaths occur among motorcyclists, as in Indonesia. However, until now, in Indonesia, there has been no monitor­ing system capable of identifying fatigue in motorbike drivers in the transportation sector. This research aims to determine fatigue patterns based on driver working hours and create a sensor system to monitor fatigue measurements in real-time to reduce the number of accidents. The research began with processing questionnaire data with Pearson correlation, which showed a close relationship between driver fatigue and driving time and a close relationship between fatigue and increased heart rate and sweating levels. From calibration tests with an error of 3% and direct measurements of working conditions, it was found that two-wheeled vehicle driver fatigue occurs after 2-3 hours of work. With a measurement system using the Box Whiskers analysis method, respondents' working conditions can also be de­ter­mined, which are divided into 4 zones, namely zone 1 (initial condition or good condition), zone 2 a declining condition, zone 3 a tired condition and zone 4 is a resting condition. Hopefully, this research will identify fati­gue zones correctly and reduce the number of accidents because it can iden­tify tired drivers so they do not have to force themselves to continue working and driving their motorbikes. As a conclusion from this research, a measure­ment system using two sensors, such as ECG and GSR can identify work fatigue zones well and is expected to reduce the number of accidents due to work fatigue.

Abstract

This research is located in conventional car washes where there are still many who use human labor in carrying out car wash activities. The posture during the car wash is considered less ergonomic, so this study aims to help car wash workers reduce their fatigue and even help their work position become more ergonomic. This research began with observations at the car wash and also interviews with workers. Interviews with the workers were conducted using the Nordic Body Map (NBM). Based on the results of observations and interviews, it was determined that the working posture was considered less ergonomic where there were three working postures, namely the posture when taking the water hose, the posture of washing the side of the car, and the posture of washing the top of the car. The three postures that are considered problematic are analyzed using the Workplace Ergonomic Risk Assessment (WERA) to determine the value of their ergonomics. When he learned that the three postures were problematic, the research continued by designing tools to reduce workload, this design was carried out using the VDI 2222 method. Designing with the VDI 2222 method there are 4 stages, namely analysis, concept, design, and completion. By using the VDI 2222 method, the concept, size, and specifications needed for belts and seats are known as a car washing aid. The last stage of this study is to re-analyze with the WERA method on all three postures but with the help of tools.

Abstract

Material handling is one of the things that is often a problem for both large companies and MSMEs. One example of a manual material handling problem occurs in MSMEs Tirta 88 as a provider of drinking water in gallons. The average sales of gallon refillable water at MSMEs Tirta 88 over the past 6 months is 348 gallons / day. Therefore, workers at MSMEs Tirta 88 have many complaints. The complaint data collection uses a Nordic Body Map (NBM) questionnaire. Then the work posture assessment using the Rapid Entire Body (REBA) method and the Workplace Ergonomy Risk Assessment (WERA). The design method used is VDI 2221. The results of this study are in the form of a new 3D gallon basket design that is in accordance with the anthropometry of workers in MSMEs Tirta 88 and will be implemented. Before being implemented, a 3D design simulation analysis was carried out in order to determine the decrease in Rapid Entire Body (REBA) and Workplace Ergonomy Risk Assessment (WERA) scores. The simulation results showed a decrease in the Rapid Entire Body (REBA) score to four for all postures and the Workplace Ergonomy Risk Assessment (WERA) to 35 for two postures and 30 for one posture.

Abstract

Today's increasingly rapid industrial development means that companies must pay attention to several things during the production process so that they can face the tough competition, one of which is by paying more attention to the quality of their products and the risks that could result in the product becoming defective so that it can meet customer satisfaction. Labor is one of the important factors that a company has, for this reason, an even workload and in accordance with capacity is one of the things that greatly influences the performance of the workforce to produce products that comply with standards. This analysis uses several methods, including: cardio vascular load, full time equivalent, and line balancing. This research aims to provide suggestions for improvements that are expected to reduce the workload of production workers and waiting times at PT. From the research carried out, it can be concluded that materials mixing workstations experience excessive workload or are overloaded so that work on these workstations is less than optimal, so that more operator power is needed or additional operators are needed at materials mixing workstations. The packing work station experiences underload or underload so it is necessary to reduce operators so that it does not become a burden on the company, especially in salary expenses.

Abstract

Turn signal lights or rearview mirror are useful as markers when you want to turn right and left when you are at a corner, a T-junction, or an intersection. By turning on one side of the light, namely the right or left, it gives information to the riders behind and in front that you want to turn. Several factors can cause motorists to forget to turn off the turn signal, such as lack of concentration or the color of the turn signal during the day is less visible. Turn signal lights that stay on can confuse other motorists. Confusion of other drivers can break the concentration of road users and cause traffic accidents. With the aim of researching the causes of turn signal lights that keep on and confuse other people, a questionnaire was distributed to motorists. The research method used is AHP by distributing questionnaires to motorists and the result is the design of a 'Smart Light Spion' for the development of motorcycle accessories.
