Abstract

Sidewalks are supporting facilities for traffic management, crossings, and people's traffic. In the case studied, it was found that part of the space on the pedestrian path was used by informal traders, for trading or other activities so that the utilization of the pedestrian path was not optimal. This study aims to reveal the utilization of Ir. Juanda Street Corridor in Depok City, related to safety and attractiveness aspects, using a quantitative descriptive method. Data was collected through questionnaires and field observations, followed up with data processing through SPSS. The results showed that the safety factor of pedestrians on the sidewalks of Ir Juanda street, Depok City was relatively low. This is indicated by the emergence of fear of criminal action due to the behavior of street vendors which is reinforced by poor physical quality. Ornamental plant traders, easy access to parking lots, and temporary market activities are aspects of the attraction, although on the other hand the presence of informal traders on the sidewalk is considered a nuisance. Keywords: Pedestrian path, safety, attractiveness

Abstract

Research on the impact of the COVID-19 pandemic on human activities has produced many new findings. This research is built on the basis of changes in the culture of student activities, which are mostly carried out offline towards a new culture in online activities. This study examines the changes in the types of activities, the place of activities and the pattern of student activities. Through quantitative research methods, data acquisition through questionnaires and descriptive analysis, found that students' weekly activities during the pandemic were quite tiring due to the increase in the number of activities. In addition, the student activities outside the campus are not effective in supporting their weekly activities as students. This is partly because of feeling bored and disturbed by other activities. Then there was a polarization of student activities during the pandemic, which can increase activity includes: sports, independent learning, running hobbies, and taking care of the house, and several decrease activities namely:  socializing, performing arts, taking care of themselves, resting, watching, medical treatment, and weekly worship. This research can contribute to finding out the learning problems of students in their hometowns during the pandemic.

Abstract

The room requires specific lighting according to its function. One way to achieve the room's optimal comfort is to adjust the natural or artificial lighting to the required standards. This research aims to study daylight intensity in the architectural classroom studio on the sixth floor of Building C Universitas Trisakti and compare it with the illuminance level requirements stipulated in SNI 6197: 2011. This study hypothesizes that the natural intensity of the room, which also functions as an architectural drawing studio, is incompatible with conventional lectures. The measuring instrument was the Lutron LM 8000A Light Lux Meter, while the natural lighting contour simulation used Dialux Evo 9. The results show that the measured natural lighting intensity is unevenly distributed. There are bright zones in the room that exceed the standard value of the illuminance level (> 350-750 lux) and dark zones that are below the standard of illuminance (<350-750 lux), with a distance of 0.5 m - 3m from a row of window openings as a source of lighting.

Abstract

The development of construction project in Indonesia is growing rapidly. In the process of building construction projects, the phenomenon of the greenhouse effect  has been taken part. Carbon emissions are one of the results of the greenhouse effect in the process of building construction projects. The foundation is one of the most important parts of construction that serves to hold the load and as a load distributor from the construction above the ground. In foundation work using reinforced concrete structures, reinforced concrete structures are a source of carbon emissions in construction projects. This study aims  to find out how much carbon emissions are produced in the drilled pile work at the GBK Multifunctional Indoor Stadium project and which element produces the largest carbon emissions. The results of this study are carbon emissions produced by one bore pile with a diameter of 800 mm of 6553,78 kg.CO2 and the work of the bore pile, which produces the greatest carbon emissions, is material consumption of 6134.40 kg, CO2.

Abstract

Infrastructure development is important in today's society. This has become an obstacle with the increasing number of residents in DKI Jakarta, because land is limited and has not been proportional to population growth. The COVID-19 pandemic has gradually paralyzed the world economic system. Currently, Indonesia is on the brink of recession. The IMF estimates that the global economy will experience a decline in growth rates of up to -3%. To determine the impact of global economic uncertainty on construction projects, the most appropriate alternative standards and strategies are needed from the criteria for technologies that are resilient to global economic uncertainty. In this research, there are 5 criteria and 3 alternatives that underlie the goal of the best strategy in the aspect of technology for Value Based Decision Making against global economic uncertainty. AHP is used to examine the importance level data by asking for opinions from 10 experts for criteria and alternatives. Based on the results of distributing questionnaires to experts, it is known that Office Building Construction is an alternative and Building Materials criteria are the most suitable criteria against economic uncertainty.

Abstract

Geopolymer concrete is a new type of concrete that does not use cement as a binder at all. In addition to replacing cement, the use of fly ash in concrete can reduce coal emissions from many coal-fired power plants. However, geopolymer concrete has drawbacks, one of which is that it has a setting time that tends to be too fast. Therefore, this study aims to determine the effect of adding borax on the hardening time and compressive strength of geopolymer concrete. With the addition of 1%, 3%, 5%, and 10% borax. The ratio of activator Na2SiO3 and NaOH is used 2.5:1 with a molarity of 10M NaOH. Variations in the addition of borax during mixing include 1%, 3%, 5% and 10% by weight of fly ash. The test results showed that the higher the borax content added, the longer the setting time. The longest final setting time was achieved in geopolymer concrete with the addition of 10% borax for 480 minutes.
