Abstract

Climate change, driven by rising greenhouse gas emissions, significantly impacts our planet. The construction sector, a major contributor to these emissions, demands a shift towards sustainable building practices. Green infrastructure (GI) offers a promising solution by integrating environmental principles into design and construction. This research investigates the understanding, challenges, and readiness of civil engineering graduates in implementing GI. Utilizing a survey-based approach with master's students at Sangga Buana University, the study analyzed the perceptions of students from different backgrounds: Civil Engineering, Other Engineering, and Non-Engineering. Results indicate that Civil Engineering students demonstrate a higher level of awareness and understanding of GI, influenced by their curriculum's focus on sustainable infrastructure development. However, challenges such as cost constraints and limited managerial support persist. Despite these challenges, civil engineering graduates exhibit a greater readiness to embrace and implement GI concepts.

Abstract

Every building renovation or building reconstruction often occurs demolition of the wall. The demolition of this wall becomes construction waste therefore it is necessary to experiment with using wall waste to become a productive material. This research is an experiment in making concrete using wall waste. The wall waste used is in the form of rubble from the ruins of a red brick wall. The compression test method refers to the 1974:2011 SNI regulations on concrete. In this test, the focus is on the maximum compressive strength of concrete that can be produced in the sample. Each sample of the test object is divided into three groups, each group has three test objects. The first group is a sample of pure concrete, fine aggregate 100% concrete sand. The second group is a fine aggregate experimental concrete sample containing 25% wall waste, and the third group contains 50% wall waste. The test object is in the form of a concrete cylinder with a diameter of 150 mm and a height of 300 mm. Concrete testing is carried out at the age of 7 days, 14 days, and 28 days. The results of this study provide information that red brick wall waste can be recycled into concrete material so that it does not become construction waste. It is known that the compressive strength of concrete using additional wall waste as fine aggregate meets the requirements of structural concrete quality and can improve the quality of concrete. Furthermore, it is hoped that the wall waste can be reused as an added material to the concrete mixture in building construction activities or other construction using concrete.

Abstract

Pedestrian pathways are crucial in urban transportation as they promote active mobility and enhance environmental quality. This study assesses the comfort of Bandung City's central pedestrian pathways, considering their physical state, supporting facilities, safety. This research investigates their interaction with the environment by employing field observations, user surveys, and quantitative and qualitative descriptive analyses. The findings reveal that several areas exhibit low levels of pedestrian comfort due to narrow pathways, uneven surfaces, and a lack of protection from weather conditions and motor vehicles. Recommendations for improvement focus on enhancing the physical quality of pedestrian routes, reorganizing pedestrian spaces, and integrating them with more inclusive public spaces. This study is expected to be a foundation for formulating policies to develop more comfortable and sustainable pedestrian infrastructure.
