Infill walls are structural components in buildings that have a room-dividing function. For structural design, infill walls are generally modeled as an open frame. However, if infill walls are combined with structural frames in modeling, these infill walls will contribute better to structural rigidity. In this research, three models have been made. Model M1 is an open frame model, model M2 is a Fully Infilled Wall Frame model and model M3 is a Fully Infilled Wall Frame model with door openings. The purpose of this study was to determine the behavior of reinforced concrete frame structures with and without taking into account the effect of the presence of door and window holes in the walls due to earthquake loads. The research method used is a quantitative method with Pushover nonlinear static analysis. The results of the analysis show that the Fully Infilled Wall Frame model is 23.97% and 8.1% stiffer than the open frame model and the Fully Infilled Wall Frame with 24.8% door openings and 41.6% window openings due to the X and Y direction earthquake loads.

Public transportation in the city of Denpasar reached its peak in the 1990s with the latest fleet being minibus-type public passenger cars with a capacity of 8-10 people. Along with the pace of motorization and ease of buying cars and motorbikes, there can be an increase in private vehicle ownership in the community. The interest of the people in Denpasar City's use of public transportation has decreased significantly. The community can finally feel and have perceptions about the difference between the advantages of using private vehicles and the quality of public transportation services. The purpose of this study was to explore public perceptions of the quality of public transport services, by distributing 400 questionnaires in all sub-districts of Denpasar City. Data on respondents' perceptions were analyzed using structural equation modeling (SEM). Based on the results of the analysis, there are seven indicators that shape people's perceptions of the quality of public transport, namely: small fleet availability, long waiting and travel times, less convenience, irregular time headway, low frequency of arrivals, and accessibility. The reduced availability of public transport is caused by long waiting times and low frequency of arrivals. Low accessibility due to long travel time. Thus, the quality of services like this in the community makes the use of public transportation in the city of Denpasar decreased.

Implementation planning is a formulation in the control of the overall construction project activities, so it will get a method or a good technical way so that with limited resources - obtained maximum results. Increase the productivity of work comprehensively to determine the value of the success of a construction project. Success in a project is also determined by equipment resources. The analysis carried out is the planning time and cost of the project, presenting the optimal time period when associated with project costs by way of shortening the completion period After obtaining the optimal time and cost the results are compared with the planning time and costs compiled by the prusahaan, the thing This is to know the time and cost efficient. Then to compile the scheduling needs of the project's daily workforce. From the analysis obtained the efficiency of time achieved by each method is, the time reached by the Manual method with the help of the pulley tool is 91 hours or rounded up to 12 days with the help of 7 workers and 1 foreman, while the time achieved by the use of tools 1 mobile crane that is 27.2 hours or rounded up to 4 days. based on the productivity of the time already achieved each method can be deduced use Launching method system more efficient 8 days in appeal using the Manual method with the help of the pulley tool. The efficiency of labor cost and tools achieved by each method ie, Costs achieved by using manual labor 26,590,200,00 using 7 workers and 1 foreman in 91 hours or rounded up to 12 working days, while the fee which is achieved by using 1 mobile crane device that is 14,071,922,28 in 27,2 hour or d to become 4 working days. The use of more efficient methods in time and the use of a labor force is the method of using a mobile crane/launching method system which can assist contractors to work within the specified time.

Slab structure work in building construction is a very important job because floor slab work has a large volume. Labor productivity is very important in carrying out a job, the output of the construction sector can be seen from the quantity of work that has been done, while the input is the amount of resources used such as labor. The purpose of this study was to determine the amount of labor required for every 1 m2 (OH) and the standard time for labor productivity in completing 1 m2 of floor slab work. The method of collecting primary data is the source of research data obtained directly, such as the number of workers and observation of sampling data, while secondary data is obtained from projects such as working drawings. The data is then processed using Microsoft Excel. This research is a type of quantitative research with a work sampling method. The results of research on floor slab work in the Udayana University Faculty of Medicine Building Construction project show that the calculation of the volume of labor per day (OH) requires 0.011 OH masons and 0.011 OH workers and the results of calculating the standard time to complete 1 m2 of floor slab work is 3.15 minutes/m2 . The Calna Villa project shows that the calculation of The volume of labor (OH) requires 0.039 OH masons and 0.039 OH workers and the results of calculating the standard time to complete 1 m2 of floor slab work is 10.37 minutes/m2.

ANALISIS PENERAPAN K3 PADA PROYEK KONSTRUKSI DI MASA PANDEMI COVID-19

The impact of the COVID-19 pandemic that has spread throughout the world has had a significant impact on the construction sector. For this reason, serious efforts are needed from all construction stakeholders so that occupational safety and health (K3) is implemented in all construction projects. In connection with the Corona Virus Disease 2019 (Covid-19) pandemic. The purpose of this study is to determine the optimal strategy for increasing the application of K3. The type of research used is combination research is a research method that combines quantitative methods and qualitative methods. Data analysis was carried out with SWOT analysis to help formulate the right strategy to improve construction implementation during the COVID-19 pandemic. The results of the SWOT matrix analysis of internal factors and external factors that affect the implementation of K3L during the COVID-19 pandemic obtained a Strength score of 2.95, Opportunity Score of 2.40, Weakness Score of 1.24, and Threat Score of 1.60. So based on the calculation of internal factors and external factors, as well as a Cartesian diagram the company's condition is in quadrant I, namely S-O (Strength-Opportunities) where this situation is a situation where the company uses strength to take advantage of existing opportunities. Meanwhile, the optimal strategy to increase the application of K3 during the COVID-19 pandemic is the Aggressive Strategy.
