Abstract

The activity of lifting weights has many risks that can lead to complaints and work accidents such as mistakes in lifting excessive loads, overly bent postures, and other complaints that result in uncomfortable working conditions. This research was conducted to determine the risk level of work posture using the REBA method and biomechanics in lifting weights with different lifting variables. The research were took documentation data, angle and distance measurements by using the Kinovea application, and the data analyzed by using the REBA Assessment Worksheet and biomechanical equations. Based on the results obtained, the activity of lifting burdens on workers from the aspect of the REBA method mostly has a high level of risk category and only 1 worker has a moderate level of risk category. Meanwhile, from the biomechanics aspect, most of them have a risk level in the careful category, 1 worker has a risk level in the safe category, and 1 worker who has lifted a load of 50 kg has a risk level in the dangerous category.

Abstract

Research on projections of greenhouse gas emissions has been carried out in the sector of transportation energy for official vehicles in Mulawarman University. The study used secondary data of fuel use of the official vehicles from 2015 until 2019 to determine the greenhouse gas emissions dominated by CO2 , CH 4 dan N2 O. The trend of the obtained greenhous gas emissions was used to predict the greenhouse gas emissions in the range of 2020 and 2030. The projections of CO 2 emissions, CH 4 emissions, and N2 O emissions, in the years, respectively, are 427,281 tons of CO2 -eq, 5,697 tons of CO2 -eq, and 5,228 tons of CO2 -eq. The calculation revealed that in the next eleven years the projection of the greenhous gas emissions due to the use of official vehicle fuel in Mulawarman University will reduce continuously.
