Abstract

This study evaluates the feasibility of microcell tower placement within an urban road environment by integrating road geometric conditions, traffic performance, roadside safety, road-space utilization, and road user perception. The study addresses a gap in existing infrastructure assessment, which tends to evaluate telecommunication facilities primarily from technical, operational, or regulatory perspectives, with limited integration of roadside safety and user-centered considerations. A descriptive-evaluative case study approach was employed at Jalan Ogan, Palembang City, Indonesia, with the primary focus on a microcell tower located on the shoulder of Jalan Ogan Tenggara. Primary data were obtained through road geometric surveys, traffic observations, roadside safety inspections, questionnaires, and interviews, while secondary data included road classification, accident information, and relevant regulations. Geometric conditions were assessed through alignment, gradient, cross-section, and sight-distance evaluation, while traffic performance was analyzed using the Indonesian Highway Capacity Guidelines (PKJI) 2023. The findings show that the road generally supports the placement from geometric and operational perspectives, with a degree of saturation below 0.20 and Level of Service A. However, the tower remains a roadside safety concern because it is positioned on or near the shoulder, its foundation is close to the road body, and adequate physical protection, warning signs, and visual delineation are not yet available. Road user perceptions similarly indicate that the tower does not significantly disrupt traffic flow but raises safety concerns related to its roadside position and limited protection. The study's principal contribution is an integrated feasibility framework that treats telecommunication infrastructure as a roadside safety object rather than solely as a digital infrastructure facility. The tower is therefore classified as conditionally feasible, subject to adequate roadside clearance, physical protection, warning devices, pavement markings, and periodic safety inspection. The findings highlight the need to align digital infrastructure development with road safety and sustainable urban transport principles.

Abstract

This study was conducted to assess the condition and quality of concrete in bridges across the Bangka Belitung Islands Province using non-destructive methods: Ultrasonic Pulse Velocity (UPV), Rebound Hammer, and crack depth testing. This evaluation is crucial for determining the extent of concrete material degradation caused by factors such as structural age, environmental conditions, and construction quality, all of which can impact bridge performance. The research involved collecting field data from various structural elements—including girders, decks, piers, and abutments—and analyzing the results against BS 1881: Part 203:1986, ASTM C597-16, and SNI 2847:2019 standards. The findings indicate that UPV values ​​ranged from 2,931 to 3,442 m/s, predominantly falling into the "medium" condition category. Estimated concrete compressive strength, based on the correlation between UPV and Rebound Hammer data, ranged from 15.60 to 33.12 MPa, with 64.29% of the bridges meeting the minimum standard of 21 MPa. Crack depth testing revealed depths ranging from 13 to 51 mm, mostly classified as shallow to medium. Overall, the combined use of UPV and Rebound Hammer methods provided complementary evaluation results regarding both internal and surface concrete quality. These findings suggest that while most bridges remain in serviceable condition, certain elements require further attention and maintenance to preserve their performance and service life.

Abstract

Soft clay is characterized by low shear strength and high compressibility. Chemical stabilization using cement and bentonite can improve soil index and mechanical properties through modifying hydraulic characteristics and soil structure. This study aims to investigate the effect of cement – bentonite combinations on the shear strength behavior of soft clay and identify the optimum mixture. Experimental investigation are conducted using the unconsolidated undrained (UU) triaxial test to evaluate the mechanical response of stabilized soil under rapid loading. Several mix composition has designed to determine the optimum mixture.  A total of 36 soil samples of  20% cement and bentonite content addition  varied from  8%, to 12% in 1% increment will be tested under confining pressures of 100, 200, and 300 kPa. The results show that maximum deviator stress increased with confining pressure whereas its relationship with bentonite was non linier. The mixture at 9% bentonite performed the highest maximum deviator stresses at all confining pressures reaching 390, 450, and 573 kPa, respectively. Further increases in bentonite content beyond 9% resulted in lower maximum deviator stress. The failure envelope analysis also indicates that increasing bentonite does not improve shear strength. Through this investigation, 9% bentonite showed the best shear – strength performance among the tested mixture. These findings highlight the importance of optimizing addiyive content to produce better mechanical performance.
