Published: July 2024

AbstractThe setting behavior of ultra-high performance concrete (UHPC) is demonstrably different from that of conventional concrete; thus, tools and guidance extending beyond common test methods such as Vicat and penetration are needed. While UHPC is known for its enhanced mechanical and durability properties, due to the low water and high cementitious contents, UHPC-class materials are prone to early-age autogenous shrinkage. Recognizing that UHPCs are commonly supplied to construction sites as prebagged, proprietary mixes with unknown constituents, and that accurate determination of setting time is crucial in determining the early-age autogenous shrinkage of UHPC-class materials as well as for scheduling construction operations and quality control actions, this study explores alternate test methods such as isothermal calorimetry (ASTM C1679), semi-adiabatic calorimetry (ASTM C1753), autogenous shrinkage (ASTM C1698), chemical shrinkage (ASTM C1608), and dual ring test (American Association of State Highway and Transportation Officials (AASHTO T 363) to evaluate the setting behavior of UHPCs. Setting times obtained using the alternate test methods aligned well with each other and were found to be different than the setting times indicated through standard test methods. Discussion and guidance on the applicability and the use of alternate test methods to determine the setting time of UHPCs for various laboratory and field applications are provided.

This study explores the enhancement of Kevlar fabric’s ballistic performance through impregnation with Shear Thickening Fluid (STF) for potential application in soft body armor. The experimental approach often fails to elucidate mechanical phenomena critical for the development of lightweight and high-strength body armor designs. To address this limitation, the finite element method, specifically using ANSYS/LS-DYNA R.13, was employed for a comprehensive analysis. The simulation aimed to evaluate the impact of STF on Kevlar fabric by assessing projectile velocity, force exerted by the projectile onto the fabric, displacement, stress distribution, and fabric failure mechanisms. Kevlar yarn was modeled as a shell element formed into fabric with a sine wave profile, investigating two types of STF: SiO2-PEG200 (S0) and SiO2-PEG200-B4C (S1), differing in maximum viscosities. The addition of STF resulted in increased coefficients of friction on Kevlar, with the highest values observed for the SiO2-PEG200-B4C impregnated fabric ( =0.87 and =0.82). The incorporation of the second STF type (S1) significantly reduced the projectile’s velocity from an initial 200 m/s to 153.2 m/s upon impact. Additionally, the force on the S1 fabric surged to 121,556 N, a threefold increase compared to neat Kevlar. STF's influence was further evidenced by enhanced fabric displacement and more uniform stress distribution upon ballistic impact. The fabric's thickening upon failure indicated STF's ability to enlarge the deformation area, facilitating uniform distribution of ballistic kinetic energy across the impact zone. Notably, the fabric impregnated with the second type of STF, featuring boron carbide (S1), demonstrated superior ballistic performance. This study concludes that STF-impregnated Kevlar fabric, particularly the SiO2-PEG200-B4C variant, not only surpasses the ballistic performance of neat Kevlar but also meets the criteria for NIJ Level IIIA standards, highlighting its potential as a highly effective material for advanced soft body armor designs.

Based on trace geological history and several studies, the Sangiran mud volcano provides insight into the geology and hydrology of the region, aquifer system in the basin, groundwater flow patterns and characteristics, rock lithology, hydrogeology condition, and saltwater trap mapping. Related to these conditions, studies were conducted on the magnetic content and composition of the major oxide compounds in the Sangiran sediments. Sample analysis was based on geochemical methods. The methods consist of frequency dependent magnetic susceptibility and vibrating sample magnetometer (VSM) analysis. Geochemical analyses using x-ray fluorescence (XRF) analysis have been conducted and various elemental grades have been determined. VSM results confirm that the magnetic content of Sangiran sediments is partly dominated by Fe (17.66 percent) contained in hematite (Fe2O3). At the same time, the samples of Sangiran sediment were enriched by Si, Fe, Al, Ca, Cl, Ti, and K according to XRF measurements. The samples exhibited the highest Si and Fe concentrations in samples T1 (Si is 29.48 percent and Fe is 13.66 percent) and T7 (Si is 24.95 percent and Fe is 12.01 percent). Meanwhile, in the T4 sample, the highest concentrations were Si and Ca, 23.45 percent and 13.45 percent, respectively. Retrieved from the magnetic susceptibility measurement, this paper confirm that Fe content is one of the components of volcanic ash in the Sangiran sediment.DOI: 10.17977/um024v8i12023p009

This article backgorunds departs from the diversity of beliefs in Indonesia, especially in the city of Medan and how to achieve inter-religious harmony through learning history. Concepts and facts about the condition of religious life in Indonesia are presented in the discussion of this article. Then, how to achieve harmony through education is explained conceptually through a history learning approach. Historical learning with the perspective of inter-religious harmony is a historical lesson that integrates the values of tolerance in the life of religious plurality. The development of this learning can raise local content and optimize historical heritage as a learning resource. Religious buildings, in this case houses of worship, are historical commodities that have the potential to be used in learning history with the perspective of inter-religious harmony. Good learning planning can realize the internalization of the values of recognition, respect and tolerance in the plurality of religions in the city of Medan through learning history. But in its development, history teachers must still refer to the demands of the applied curriculum. Harmonization pursued through learning history is believed to be an important social capital to create stability in national development. Latar belakang penulisan artikel ini berangkat dari keberagaman berkeyakinan di Indonesia khususnya di Kota Medan dan bagaimana mewujudkan kerukunan antar umat beragama melalui pembelajaran sejarah. Konsep dan fakta data kondisi kehidupan beragama di Indonesia disajikan dalam pembahasan artikel ini. Kemudian, bagaimana upaya-upaya mewujudkan keharmonisan tersebut melalui pendidikan diuraikan secara konseptual melalui pendekatan pembelajaran sejarah. Pembelajaran sejarah berwawasan kerukunan antar umat beragama adalah pembelajaran sejarah yang mengintegrasikan nilai-nilai toleransi dalam kehidupan pluralitas beragama. Pengembangan pembelajaran tersebut dapat mengangkat konten-konten lokal dan mengoptimalkan peninggalan sejarah sebagai sumber belajar. Bangunan-bangunan keagamaan dalam hal ini rumah ibadah merupakan komoditi sejarah yang sangat potensial digunakan dalam pembelajaran sejarah berwawasan kerukunan antar umat beragama. Perencanaan pembelajaran yang baik dapat mewujudkan internalisasi nilai-nilai pengakuan, penghormatan, dan toleransi dalam pluralitas beragama di Kota Medan melalui pembelajaran sejarah. Namun dalam pengembangannya, guru sejarah harus tetap mengacu kepada tuntutan kurikulum yang diterapkan. Harmonisasi yang diupayakan melalui pembelajaran sejarah ini diyakini sebagai suatu modal sosial penting untuk menciptakan stabilitas dalam pembangunan bangsa.
