<![CDATA[The increasing consumption of natural aggregates in concrete production encourages the utilization of alternative waste materials that can partially reduce dependence on conventional resources. This study investigates the effect of rice field snail shell powder as a partial substitute for fine aggregate on concrete workability, density, and compressive strength. A laboratory experimental method was conducted using five substitution levels of 0%, 2.5%, 5%, 7.5%, and 10%. The rice field snail shells were processed into powder passing the No. 100 sieve, and cylindrical concrete specimens with a diameter of 150 mm and a height of 300 mm were prepared and water-cured for 28 days. The average slump values were 165, 150, 137.5, 155, and 160 mm, respectively. The 28-day average compressive strengths were 28.26 MPa for the control concrete, 29.97 MPa at 2.5%, 22.33 MPa at 5%, 26.05 MPa at 7.5%, and 25.05 MPa at 10% substitution. The 2.5% mixture achieved the highest average compressive strength, while higher substitution levels did not consistently improve mechanical performance. The results indicate that rice field snail shell powder can partially replace fine aggregate, although its effectiveness depends on the substitution proportion and consistency of the concrete mixing process.]]>

<![CDATA[Housing development projects are required to achieve cost, quality, and time targets efficiently, creating a need for effective cost-control methods that do not compromise building function and quality. This study aims to identify more economical material alternatives and determine the potential cost savings from applying Value Engineering to the architectural works of the Mutiara Kedungmundu Housing Project in Semarang City. A case study approach was employed through four Value Engineering stages: information, creative, analysis, and recommendation. Data were obtained from the project’s Bill of Quantities, Unit Price Analysis, and working drawings, and were analyzed using cost breakdown, Pareto analysis, function analysis based on Cost/Worth, Zero-One analysis, and an evaluation matrix. The results identified five architectural work items with high optimization potential, namely walls, door and window frames, floor and wall finishing, roof, and ceiling. Seven selected material alternatives reduced the architectural work cost from Rp155,832,330.69 to Rp144,998,247.48, generating a saving of Rp10,834,083.20 or 6.95% of the initial cost. The selected alternatives maintained the primary building functions, quality, and aesthetic requirements. These findings demonstrate that Value Engineering provides an effective systematic approach for optimizing construction costs in small- to medium-scale housing projects while maintaining essential building performance.]]>
