Internal friction angle (φ) is one of the important parameter in a foundation engineering, especially in the stress distribution event. The higher value of the internal friction angle shows the higher of the material can withstand the lateral force. Cohesion factor (c) is also an integral part of the shear strength for the foundation material. In the granular soil such as sand or non-cohesive material, including aggregate, cohesion value usually assumed as zero, although some cohesion factor may be applied. In this research, two different materials were tested for their shear strength. The materials were Natural Crushed Aggregate (NCA) and Recycled Concrete Aggregate (RCA). Each material was also tested under two different circumstances. First, the materials were tested in a small-scale direct shear (SSDS) test with the maximum material size of 0.425 mm and 2.0 mm. Secondly, the materials were tested in a large-scale direct shear (LSDS) test with the graded size of aggregate according to road base layer specification. The SSDS showed the internal friction angle of NCA and RCA varies from 26.20 to 29.82 degrees. Whereas the LSDS showed the internal friction angle of NCA and RCA are 44.90 and 29.16 respectively. Both of SSDS and LSDS also showed the cohesion value of NCA and RCA.

Urban traffic congestion worldwide leads to air pollution, increased vehicle noise, and longer travel times for both private and public transit. Congestion adversely affects the well-being of road users and urban residents, and traffic accidents are closely linked to congestion. Traffic composition, road infrastructure, environmental conditions, vehicle design, and human behavior can cause congestion. Concrete block pavement is a practical option for improving traffic safety and increasing driving comfort at intersections with traffic lights. Concrete block paving roads are a cost-effective engineering solution for residential, commercial, municipal, and industrial environments. The study uses the Autocad program to create a simulation of a paved surface and a research tool to analyze the model of the research subject. Results indicate that pavement types subjected to higher loads exhibit more deformation than those under lower loads. Pavements with higher weights are more likely to deform, with the Herringbone 90° pavement type able to withstand a maximum load of 2100 kg and exhibiting the highest load deformation rate of 0.21 cm/kg. The study investigates the load-bearing abilities of different pavement kinds and patterns. The Basketweave pavement type has the lowest load capacity at 2077.9 kg and the lowest load deformation rate of 0.41 cm/kg.

Traditional market areas with high activity intensity create convergence of multiple traffic movements, leading to congestion and increased pedestrian-vehicle conflicts. This study aims to analyze risk mitigation and formulate strategies for improving pedestrian safety at the Pasar Induk Brebes using an integrated approach. A quantitative descriptive-evaluative method was applied, collecting data through traffic surveys, pedestrian facility audits, and questionnaires involving 110 respondents. Analysis covered traffic performance using MKJI 1997, pedestrian Level of Service (LOS), Walkability Index, inferential statistical tests (Mann–Whitney, Spearman, and Chi-Square), and SWOT analysis. Results show road segments operating at LOS B (V/C = 0.39) with high side friction, while the signalized intersection records DS > 1.0 on two main approaches. Pedestrian facilities are suboptimal: effective sidewalk widths of 2.5 m (east) and 1.2 m (west), LOS B–C at peak hours, and a PV² value of 2.33 × 10⁹ recommending a Pelican Crossing, yet no formal crossing facility currently exists. The Walkability Index averages 42.86 (marginal category). Mann–Whitney tests confirm significant gender-based perception differences (p < 0.05); Spearman correlation reveals a very strong relationship between traffic conflict and walkability index (ρ = 0.917, p < 0.001). SWOT-based strategies propose installation of Pelican Crossing, inclusive sidewalk rehabilitation, side friction management, and strengthened traffic enforcement.
