Analysis of Three Armed Signal Intersections With MKJI 1997 Method

Bekasi Regency is a regency in West Java Province with a population of ± 3,899,00 Million People (Based on Statistics Indonesia, 2020). Diponegoro Highway – Setia Mekar Street Bekasi Regency is access to the main road to the city border, besides that access to residential locations, schools, and many companies which makes vehicle traffic especially during rush hour more congested by the activities on the side of the road such as slow vehicle, the ups and downs of passengers, so vehicles that stop causing long vehicle queues. From the results of the analysis, the results of signalized intersection can be obtained on the Diponegoro Highway Setia Mekar Street Bekasi Regency. It is known that the greatest Degree of Saturation is in the Northen approach which is 1,12 with a average intersection delay is 99,21 seconds/smp. Furthermore, Alternative solutions is carried out by changing side obstacles from 0,94 to 0,95 and recycling time intersection, resulting in a decrease in the average intersection delay and improvement of indoporlen intersection service

PUSHOVER ANALYSIS OF THE STRUCTURE A 10 FLOOR BUILDING WITH ATC-40

The concept of earthquake-resistant buildings is very meaningful to try on buildings located in certain earthquake areas, especially in Indonesia considering the situation which is located in a shock area with a fairly high intensity of events. The purpose of this research is to determine the seismic performance criteria of the planned structure using the SMRF (Special Moment Resisting Frame) structural system from the results of the displacement values using the ATC-40 code, showing the yielding scheme (plastic joint distribution) that occurs from the calculation results of the software program, knowing the pattern of building collapse so that it can be known joint- joint that is damaged and damaged from the pushover analysis. From the results of the research, the building structure is able to provide nonlinear behavior which is indicated by the initial phase and the majority of the occurrence of plastic joints occurs in new beam elements and then column elements and has fulfilled the earthquake-resistant building concept, namely strong column - weak beam. The results of the structural performance evaluation according to the ATC-40 rule that the Performance Level of the SMRF building in the x and y directions is at a Performance Level of 0.011 in the Immediate Occupancy (IO) category where the building is safe during an earthquake, the risk of loss of life and structural failure is not too significant, the building does not experience significant damage, and can be reused and not disturbed by repair problems, where the strength and stiffness are approximately the same as the conditions before the earthquake

Study of Behavioral of Vertical Irregular Building Structure by Applying Column Variation Due to Earthquake using Dynamic Analysis

The development of high-rise buildings in Indonesia is now increasingly diverse. The need for increasingly narrow land functions affects the shape of the building which tends to be irregular. Irregularity in the building requires structural planners to build buildings that are safe against earthquakes but also do not forget the aspect of user comfort. In this study, an analysis of the dynamics of earthquakes was carried out in buildings that have vertical geometric irregularities by varying the dimensions and reinforcement of the columns. The behavior of the building structure produces structural responses in the form of base shear, fundamental period, displacement and story drift. Analysis of earthquake using dynamic analysis of response spectrum based on SNI 1726 2019 with the help of ETABS software version 9.7.4. The results of this research indicate that the variation of column dimensions and column reinforcement in buildings with irregular vertical geometry reduces the stiffness of the building thereby reducing the forces in the structure, increasing the fundamental period, reducing the base shear force, increasing the displacement and the story drift

Identifying Accident Severity Factor On Surabaya Secondary Arterial Roads

One of the CBD (Central Business District) areas of Surabaya is located at the center of the city, which is also known as the CBD Tunjungan area. CBD Tunjungan area is a hub for trade and services and has important accessibility which is surrounded by secondary arterial roads. Some secondary arterial roads which have access and high mobility to the CBD Tunjungan Area are Darmo Raya Road, Urip Sumoharjo Road and Basuki Rahmat Road. The high activity and mobility in the CBD area cause several transportation problems, one example is traffic accidents. The traffic accident data by the Directorate of Traffic and City Resort Police of Surabaya show that there are quite a several traffic accidents on these two roads. Traffic accidents are divided into three levels of severity i.e. slight, serious, and fatal injuries. To obtain the probability model of traffic accidents within every accident severity, it is necessary to do an analysis using the multinomial logistic regression method. The independent variables such as vehicle speed, lane width, accident time, and accident type, are considered to affect the equation model. Thus, it can be discovered the variables that affect the probability at the three levels of traffic accident severity

Comparison Analysis of Cost and Time Forming Conventional Method With Semi-System Method for Column Namira Hotel Surabaya

In the implementation of project activities, careful steps are needed and the determination of the right implementation method to obtain cost and time efficiency. In general, there are 3 types of formwork, namely conventional formwork, semi-system formwork, and system formwork. The difference between the three types can be seen from the material used. This study aims to determine the comparison of formwork in terms of method, cost and time in the construction of the Namira Hotel project located on Jl. Pagesangan Surabaya which consists of 9 floors. The cost of formwork is usually between 35% to 60% or more of the total construction cost. Material requirements are usually referred to as the calculation of the volume of work. The volume of a formwork work depends on the planned area. The duration needed to complete a job is influenced by the worker. So in order to determine the success of a project, the factors that must be considered are in terms of labor productivity and the number of workers. In the construction of Hotel Namira Surabaya, the cost of conventional column formwork was IDR 376,052,918.80 and for semi-column formwork it was IDR 214.624.700,00 where the duration of semi-system formwork was faster than conventional formwork

Analysis of Health and Safety Risk Management (OHS)

This study intends to identify OHS risks in the workforce, control risks, and assess risks that occur in construction projects. This implementation was carried out in the KPP Sidoarjo State House Rehabilitation project. This data collection uses the interview method and filling out questionnaires directly to the workforce as many as 15 respondents who then arrange the risk potential variables based on each job so that 37 potential risk variables are produced. In the conclusion, there are results of the risk level assessment based on the AS/NZS 4360 standard, there are 20 variables that are categorized as medium level and 17 variables that are categorized as low level. exposed to noise when using a grinding machine when cutting ceramics (ceramic installation process), while for the lowest value of 1.47 which is included in the low level, the workers' eyes are exposed to paint splashes (painting process)
