Abstract

Occupational health and safety in Indonesia are crucial for improving worker safety and reducing the high incidence of construction-related accidents. In the research conducted on the construction of the Joint Lecture Building at a University in Malang City, a comprehensive analysis will be carried out to manage OHS risks, minimize workplace accidents, and improve work safety. By identifying hazards from each task and determining risks, risk controls for this construction project will be obtained. The work to be studied includes lower structure and upper structure tasks of the project. The research results show that risk control using the HIRARC method identified 52 hazards and risks. The risk analysis for lower structure tasks revealed five extreme risks, ten moderate risks, and four low risks, while the risk analysis for upper structure tasks revealed eight extreme risks and twenty-five moderate risks. The dominant hazard identification factors were machine-related, with seventeen hazard identifications dominated by heavy equipment hitting workers. The second factor was material-related risks, with workers being struck by falling materials and stepping on sharp objects. The third factor was worker-related risks, with seven identified risks dominated by workers falling from heights, followed by work method-related risks with seven identified risks dominated by improper worker positioning causing health issues. The final factor was environmental, with seven identified hazards dominated by landslides. Risk control is divided based on the causes of hazards, namely man, machine, material, method, and environment. Risk control is carried out by identifying based on the five HIRARC control hierarchy levels: elimination, substitution, engineering control, administrative control, and PPE.

Abstract

A lot of energy consumed by large hotel buildings can affect the environment degradation in a long period of time. Every building plan, including hotels must consider an integrated balance in utilizing existing and limited resources based on low CO2 emissions. Excessive use of energy has a negative impact which increasing the amount of CO2 emissions. This research aims to determine the effect of energy efficiency to provide recommendations, which require significant reduction of energy and environmental degradation by minimizing energy use and CO2 emission. The method that used in this research are modelling, and simulate the energy use intensity and carbon emission using Sefaira as a Sketchup Software plug-in by simulating the existing design and provide a recommendation. The object that being used in this research is a hotel building that have 11 floor and 1 basement in Yogyakarta, Indonesia. The result shows EUI of existing hotel building is 977 kWh/m2/year and carbon emission 1.872.042 kgCO2e/year. Comparing to the EUI standard which at the limit of 290–400 kWh/m2/yr. It is recommended to build additional window at the dismantled room area on north and south side of the hotel’s corridor. The recommended design, provides a reduction of EUI into 744,22 kWh/m2/year (31,28%). Meanwhile the carbon emission reduced into 1.467.072 kgCO2e/year (27,60%) from the existing design.

Abstract

Hospitals are social facilities that operate publicly for 24 hours/day. The energy consumption of hospital buildings is among the highest, compared to commercial and residential buildings. Energy efficiency can be achieved after implementing a process called energy auditing and planning. The purpose of this study is to determine the EUI (Energy Use Intensity) of electricity for energy and cost savings, without reducing the productivity and comfort of the occupants. The method used in this research is the calculation of the EUI of the entire equipment, comparison of calculating the existing EUI with the Standard, simulation of existing conditions, redesign, modeling and simulation analysis of redesign results, calculation of EUI after redesign and calculation of energy costs before and after redesign. The results of this study obtained the EUI value in the air-conditioned room on the 1st floor of 15.14 kWh/m2/month included in the category Sufficient efficient from previously Wasteful, 2nd floor of 7.53 kWh/m2/month included in the category Fully Efficient and 3rd floor of 7.97 kWh/m2/month included in the category Fully Efficient. As for the non-AC room, the 1st floor of 2.27 kWh/m2/month is included in the Fully Efficient category, the 2nd floor of 2.50 kWh/m2/month is included in the Fully Efficient category from the previous Efficient, and the 3rd floor of 2.50 kWh/m2/month is included in the Fully Efficient category from the previous Efficient. Meanwhile, the calculation of energy costs after design recommendations was obtained at IDR 976.219.477,27 decreased by 21.56%.
