Abstract

The rapid development of infrastructure has led to an increase in demand for infrastructure materials. The use of natural materials in concrete production is becoming increasingly uncontrolled with the continuation of current infrastructure development. With the increase in marble production in Indonesia, the marble powder waste produced has become an environmental problem that needs to be addressed. This study aims to determine the compressive strength of concrete with the addition of 0%, 15%, 25%, and 35% marble powder waste. The research design used in this study is quantitative with a experimental research type. Data analysis uses the ACI (American Concrete Institute) standard. The test specimens in this study were made using cylinders with a diameter of 15 x 30 cm with a planned concrete compressive strength of ƒʾϲ 21.7 MPa. The percentage of marble powder waste used varied between 0%, 15%, 25%, and 35% with a planned age of 7 and 28 days. The results showed that the addition of marble powder waste affected the compressive strength of the concrete, with an optimal value of 23.79 MPa achieved at 28 days with a variation of 15%.

Abstract

The problem of traffic congestion has not yet been fully resolved in Indonesian cities such as Malang. One of the areas most prone to traffic jams is the intersection of Sudimoro Street and Lowokwaru District. Due to the lack of traffic signs at that location, vehicles drive erratically, disrupting traffic flow. Because it is located in an area frequented by young people—such as cafes and trendy hangout spots—the intersection of Sudimoro Street and Ikan Tombro Street, particularly north of the airplane roundabout, experiences fairly heavy traffic. This research approach, which examines the current performance of the interchange and its projected performance in 2030, is based on the Indonesian Road Capacity Guidelines (PKJI 2023). The interchange currently has a capacity of 2,664.56 vehicles per hour, a saturation level of 0.70, an average delay of 11.89 seconds per vehicle, and a queueing probability ranging from -0.21% to 40.67%, according to the study’s findings. The interchange’s service level is classified as Class F. According to projections, traffic volume will reach 3,550.24 vehicles per hour by 2030, the saturation level will rise to 1.33, and the service quality will remain in Class F.

Abstract

The reliability of irrigation infrastructure plays a crucial role in supporting agricultural productivity and the sustainability of water distribution. Over time, the physical components of irrigation networks are prone to degradation due to aging, hydraulic loads, sedimentation, and limited maintenance. This study aims to assess the existing physical condition and analyze the physical performance of irrigation structures in the Tumpukrenteng Irrigation District, Turen Subdistrict, Malang Regency, which serves approximately 98 hectares of agricultural land. The study focuses on physical infrastructure aspects, including main structures, conveyance channels, and ancillary structures. The research methodology involved field inspections, visual surveys of structure conditions, and direct measurements of damage levels supported by secondary technical data. The inventory data were analyzed using a weighting method based on the Irrigation System Performance Index standards, with an emphasis on physical infrastructure indicators. The results of the study indicate that, in general, the irrigation network remains in good condition; however, there are some localized damages such as minor cracks, surface peeling, sedimentation, and the growth of wild vegetation on certain canals and structures. These conditions have the potential to reduce flow efficiency and increase water loss if not addressed promptly. The physical performance metrics obtained indicate that the irrigation system is still functional but requires periodic maintenance and targeted repairs. In conclusion, this study provides a quantitative and objective assessment of the physical performance of the irrigation network, which serves as a basis for determining priorities for ongoing maintenance and rehabilitation.
