Abstract

Purpose of the study: The study aims to determine empirical conversion coefficients between compressive strength (f'c) and flexural strength (fs) for a 20 MPa rigid pavement concrete design and to evaluate the specific effects of local South Sumatra aggregates combined with three distinct regional cement brands. Methodology: Laboratory experimental methods utilized 18 specimens (9 cylinders, 9 beams). Aggregates underwent sieve analysis, specific gravity testing, and moisture testing in accordance with SNI standards. Mechanical tests used a compressive strength machine and a two-point loading flexural apparatus. Materials comprised Musi River sand, Baturaja gravel, and Baturaja, Tiga Roda, and Dynamix cements. Data analysis used linear regression models. Main Findings: All variations exceeded the 20 MPa design target. Dynamix cement achieved the highest mean compressive strength (26.23 MPa), while Baturaja cement produced the highest mean flexural strength (3.22 MPa). The derived empirical conversion coefficients (fs √f’c) were 0.67 for Baturaja, 0.66 for Tiga Roda, and 0.62 for Dynamix. The collective correlation yielded a linear regression equation of y = 0.0219x + 2.6131 with R² = 0.2731. Novelty/Originality of this study: This study establishes unique, brand-specific empirical conversion factors for pavement concrete formulated with unique South Sumatra regional aggregates. It directly advances existing engineering knowledge by demonstrating how localized combinations of raw materials deviate from generalized national standard formulas, enabling field engineers to confidently perform rapid quality control without resource-intensive on-site beam trial mixes.

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 explores how the maritime cultural heritage of Kampung Perigi, Palembang, Indonesia, can inform a conceptual design for citizenship learning through the Living Lab Citizenship approach. A qualitative ethnographic approach was employed, with fieldwork conducted from January 20 to February 3, 2026. Data were collected through observations, semi-structured in-depth interviews, and documentation involving four informants: a community leader, a traditional boatbuilder, a maritime archaeologist, and a historian specializing in South Sumatra. The data were analyzed using Reflexive Thematic Analysis combined with ethnographic interpretation. The findings highlight the intergenerational transmission of boatbuilding knowledge, the historical relationship between community life and the Musi River, and the continued practice of traditional boat construction and repair. Interpreted through the perspective of cultural citizenship, these practices provide a contextual basis for examining cultural identity, belonging, and participation in community life. Through pedagogical reconstruction, the findings inform a proposed Living Lab Citizenship design comprising four stages: ethnographic exploration, cultural citizenship reflection, pedagogical reconstruction, and civic action and reflection. The design identifies civic knowledge, civic skills, and civic dispositions as intended dimensions of citizenship learning. Its contribution lies in connecting living maritime heritage, cultural citizenship, and pedagogical reconstruction within an ethnographically grounded conceptual framework. However, the design has not yet been implemented or empirically tested in an educational setting; its pedagogical feasibility and contribution to students' civic competence require further implementation, validation, and evaluation.
