Abstract

Concrete is a material that is widely used in construction. Concrete research efforts are ongoing and through a series of experimental tests. On the other hand, experimental tests require a lot of money, take a long time, and create waste. Several studies have revealed that numerical testing can accurately test concrete to fractures. However, modeling for the four-point load flexure test pattern is still not widely discussed. This study aimed to model the four-point flexural test of concrete using the discrete element method (DEM) approach. Sieve gradation was performed to determine particle size, and flexure testing was performed to calibrate the DEM model. DEM flexure testing was made using Yet Another Dynamic Engine (YADE) software with ASTM D6272 reference and beam dimensions 105 x 105 x 535 mm. The cohesive contact model with spherical particles is used, and the algorithm developed modifies the faceted sphere of interaction. The study results revealed that DEM can simulate crack behavior in flexural testing of unreinforced concrete. The DEM results show only a 2.13% difference in the experimental results of the flexural strength test. Meanwhile, crack behavior can be observed directly in the DEM simulation. The results of this study can be used to predict the failure pattern of the flexural test structure and to design the right proportion of the mixture to match the desired flexural strength. So that material efficiency and concrete flexure testing time can be achieved.

Abstract

Introducing alternatives material on cement-based material manufacturing is the need for environmental sustainability due to the excessive mining of sand from quarry and river bed. At the same time, industrialization headed to an uncontrollable growth of waste. This fact encourages the researcher to enhance the utilization of recycled waste in construction practice. On one side, it affords a solution for waste management, and on the other hand, it contributes to an eco-friendly construction material that minimizes the environmental impact. This paper aims to investigate the usability of the iron waste obtained from the wrought iron industry, as natural fine aggregates replacement. In particular, it focused on studying the physical characteristic of waste aggregates and the effect of partial replacement of natural sand on mortar strength. Mortar cube specimen made with various levels of replacement (0%, 10%, 20% and 30 %) and also various cement-aggregates volumetric proportion, which are 1:3, 1:4, 1:5, 1:6, and 1:7. All of the measurement parameters are taken consecutively based on ASTM norms. The current work remarks that both waste aggregates and natural aggregates reveal complete fulfillment in the aggregate requirement of ASTM standard. Furthermore, the mortar cube test confirmed that the mortar passes the strength grade for N class and O class, which suitable for the above-grade and non-load bearing application.

Abstract

This paper examines the correlation between compressive strength, porosity, and ultrasonic wave propagation in mortar. The research was conducted at the Yogyakarta State University Building Materials Laboratory. The study used an experimental method, mortar was made with variations in the ratio of cement and fine aggregate 1:3, 1:4, 1:5, 1:6, and 1:7 with a phase of 0.48. The manufacture of test objects in the form of a cube measuring 5x5x5 cm refers to SNI 03-6825-2002. Tests were carried out at the age of 3, 7, 14, 21, and 28 days with three samples per test age. The data was processed by quantitative descriptive method to determine the relationship between the variables, especially the relationship between wave propagation speed and compressive strength, as well as its relationship with the porosity value. The results of compressive strength and wave propagation speed are directly proportional to the age of the test. With the results of the compressive strength at 1:3, 1:4, 1:5, 1:6, and 1:7 variants, respectively 31.12 MPa, 19.83 MPa, 12.25 MPa, 5.38 MPa, and 3.89 MPa and wave propagation speed of 3827.67 m/s, 3641.7 m/s, 3561.3 m/s, 2019,0 m/s, and 1691.0 m/s. Then the porosity values are 11.12%, 12.88%, 16.36%, 17.60%, and 22.06%. The compressive strength has a correlation that is directly proportional to the logarithmic speed of wave propagation, the higher the value of the compressive strength, the higher the UPV value, and inversely proportional to the porosity value as well as the speed of the wave propagation which is inversely proportional to the porosity value. The higher the porosity value, the lower the compressive strength value and the UPV value.

Abstract

In general, the building evaluation requires a sample from the building being tested. However, this cannot be done in cultural heritage buildings such as Masjid Gedhe Mataram. Because of that reason, an Ultrasonic Pulse Velocity test (UPV) is applied. This test aims to determine the strength of the wood quality due to the influence of its water content using the ultrasonic pulse velocity direct method. In the UPV test, the results are in the form of wave propagation which is influenced by several factors such as the type and the water content of the wood. There were 3 types of tested wood, 9 specimens each. The types of tested wood were kruing (KR), sengon (S), and teak wood (JTB). The water content was set at 12%, 15%, 20%, 25%, and 30%.The results showed a strong correlation between MoE and MoEd values of kruing wood with an R2 value of 0.8405, a weak correlation of sengon wood with an R2 value of 0.31, and a strong correlation of teak wood with an R2 value of 0.9331. The differences in wood quality based on modulus of elasticity between bending testing and UPV were 0.9 - 4.43% for kruing wood, 3.23 - 23.4% for sengon wood, and 3.4 - 33% for teak wood.

Abstract

Banyu Bening, an independent community group providing clean water and sanitation services, faces challenges related to energy consumption and water distribution management. The primary issue addressed was the high electricity cost for operating water pumps during the early stages of the business. This problem was particularly critical as the group was newly established and required appropriate technology to overcome these obstacles. Therefore, the main objective of this Community Service Program was to address Banyu Bening’s problems—specifically, the high electricity consumption and low water pressure in the distribution network. The problem-solving process involved several steps: situation analysis, focus group discussions (FGD), material identification, assembly and testing, installation, community socialization, and evaluation. The implemented solution was the installation of a 2kWp solar power system. The final assessment revealed that the system operates optimally, successfully reducing electricity costs by 70 percent.
