Non-Smoking Areas based on a Total Ergonomics Approach Reduce Cigarette Smoke Exposure and Fatigue in Denpasar City Restaurant Workers

28th of January, 2022

A hybrid Doctoral Promotion for the candidate of I Made Kerta Duana, SKM., MPH with the title "Smoking-free Area" was held at the Prof. dr. I Goesti Ngoerah Gde Ngoerah venue. Reducing Exposure to Environmental Tobacco Smoke (ETS) and Fatigue in Denpasar City Restaurant Workers Using a Total Ergonomic Approach Dust, steam, gas, and other toxic elements are frequently present in the workplace, interfering with productivity and endangering workers' health. Exposure to cigarette smoke is one of the biggest contributors to indoor air pollution in restaurants. Worker weariness as a result of ETS exposure.

According to the findings of this study, improving the work environment through KTR based on the Total Ergonomics Approach can significantly reduce ETS exposure in restaurants by 41.4 percent, worker fatigue by 12.15 percent, CO exposure in workers by 26.92 percent, and nicotine exposure by 27.07 percent in the Intervention group. In addition, KTR based on the Total Ergonomics Approach enhanced restaurant KTR compliance by 150 percent above standard KTR and increased restaurant revenues by 34.37 percent.

The SHIP Approach is emphasized at every level of the problem-solving process by focusing on the Appropriate Technology Approach in this study's KTR model based on the Total Ergonomics Approach (TTG). Furthermore, the participation component is critical in the creation and execution of the agreed-upon problem-solving solution, namely the adoption of the Regional Regulation on KTR in Restaurants based on the Total Ergonomics Approach. This model is a collection of materials and standards for implementing KTR in restaurants that was created using a systems approach that considers all of the factors that influence KTR implementation.

To produce optimal restaurant workstations, the Total Ergonomics approach is implemented as a unified system with a comprehensive work environment improvement method, resulting in an increase in Indoor Air Quality, a decrease in ETS exposure to workers, and an increase in restaurant compliance with KTR implementation. The restaurant's work environment is free of cigarette smoke pollutants, which has a direct influence on improving indoor air quality and reducing workers' exposure to cigarette smoke, hence reducing the risk of disease caused by smoking and promoting workplace comfort and productivity. This situation will eventually have an impact on enhancing worker health and performance in order to achieve optimal productivity levels.

The development and modification of the concept of KTR application with a Total Ergonomic Approach, which is fully applied in solving health problems and improving air quality from cigarette smoke exposure through the development of a No Smoking Area Module based on a Total Ergonomic Approach, is the result of this novelty. This module provides instructions for creating a No Smoking Area that can be used in restaurants to reduce ETS exposure, nicotine exposure, CO exposure, worker tiredness, and boost KTR compliance and earnings. Researchers have identified various benefits as a result of the novelty component, including a reduction in ETS exposure for workers, as well as a reduction in nicotine and CO exposure for workers, a reduction in worker nicotine and CO exposure, a reduction in worker tiredness, an increase in KTR compliance, and an increase in business profitability.
