Issues of industrial waste recycling are very relevant for the entire global scientific community. The search for technological solutions that would allow the production of high-quality materials using industrial waste will not only reduce the environmental load, but also expand the raw material base for the production of gypsum materials. The study examined the possibility of improving the surface quality of molded gypsum samples by replacing the metal mold with a plastic one and introducing a surfactant into the raw mixture. As a result of the research, it was found that the use of a surfactant and a plastic mold allows to avoid defects on the surface of the samples. At the same time, the use of a plastic mold, which has low adhesion to the citrogypsum-based binder, helps to reduce the amount of adhesion friction and optimize the raw mixture compaction process. This makes it possible to obtain samples with improved physical and mechanical characteristics (compressive strength increases by 30–85.5%, average density - by 1.7–2.7% and water absorption decreased by 1.7–16%) or lower consumption of binder up to 20% compared to samples prepared in metal mold.

The economy of Bali heavily relies on the tourism sector, leading to economic vulnerability. There are numerous challenges in Bali's economy, with COVID-19 being one of the most prominent examples. During the COVID-19 pandemic, Bali's economy experienced the deepest contraction and slowest recovery compared to other provinces in Indonesia. Amid this economic vulnerability, it is important to conduct research on the financial resilience of SMEs in Bali. This research aims to analyze the influence of financial literacy on financial resilience, as well as the mediating role of financial performance and fintech adoption on the impact of financial literacy on financial resilience among SMEs in Bali. The research method used is a quantitative approach with a sample of 177 SMEs in Bali, selected through non-probability sampling techniques. Data were analyzed using descriptive and inferential statistics, with SEM-PLS in SmartPLS 3.0 program. The test results indicate that financial literacy has a positive and significant influence on financial resilience, financial performance, and fintech adoption. Financial performance and fintech adoption also have a positive and significant impact on financial resilience. Furthermore, financial performance and fintech adoption can partially mediate the influence of financial literacy on financial resilience in SMEs in Bali.

Offshore oil exploration in deeper waters has necessitated the development of lighter mooring systems to replace traditional steel cable and chain platforms. This study focuses on evaluating the mechanical behavior and fatigue degradation mechanism of high modulus polyethylene (HMPE) fibers in yarn-on-yarn abrasion tests. Initial characterization tests, including linear density, rupture force, and thermal analysis, were conducted on HMPE yarns. Yarn-on-yarn abrasion tests were performed under dry, wet, and salty conditions, with varying loads, while statistical analysis examined the influence of environmental factors and load levels on yarn performance. Scanning electron microscopy (SEM) analysis provided insights into material degradation mechanisms. Results showed superior performance in freshwater-immersed yarns due to cooling and lubrication effects, while dry conditions led to material melting. SEM analysis revealed critical degradation zones, particularly in interwoven regions, where increased friction and heat concentration caused material fusion. Degradation evolution mechanisms highlighted fatigue-induced rupture of yarns, knot formation, and material melting near failure points. This comprehensive analysis enhances understanding of HMPE yarn performance and degradation in offshore mooring applications, laying the groundwork for developing advanced mooring systems capable of withstanding deep-sea environments.

Low-speed impacts are common occurrences in industries such as aviation, automotive, and marine. Yet they have received relatively little attention compared to medium and high-speed impacts. Understanding the behavior of materials under low-speed impact is crucial for ensuring impact resistance and damage absorption in engineering structures. This study presents an experimental investigation into the low-speed impact behavior of 1050 aluminum alloy plates. Impact tests were conducted using a CEAST 9340 drop-weight testing machine, varying impact energies and temperatures to analyze their effects on the material. The findings highlight the importance of understanding the dynamic response of engineering materials under low-speed impact loading conditions. The insight gained from this study informs the design and optimization of aerospace and automotive structures to enhance their impact resistance and structural integrity. The results of the study indicate an inverse relation between the temperature of the impacted specimen and the maximum contact force.

The permanence and durability of mechanical and structural elements with discontinuities such as cracks and voids require the calculation of SIF (stress intensity factors) with reasonable fidelity. SIF is a crucial parameter that predicts crack growth and failure behavior by quantifying the stress field neighboring the crack tip. Therefore, understanding the sophisticated characteristics of the stress fields in the vicinity of discontinuity requires an effective way of calculating SIFs. Currently, there are numerous methods to calculate SIF, such as FVM (Finite Volume Method), FEM (Finite Element Method), BEM (Boundary Element Method), XFEM (Extended Finite Element Method), Phase field method and Meshfree methods. For an extended period, FEM is one of the leading methods in solving fracture mechanics problems. Though FEM is quite robust in dealing with several engineering problems, it has got its inherent drawbacks to deal with singular fields like discontinuities. Hence to reasonably capture moving discontinuities, finer meshes near the discontinuous field are required that demand more computation effort and time. To alleviate the above drawback of FEM, this study employed Extended Isogeometric Analysis (XIGA) to efficiently and effectively determine the SIFs in the case of fissured plates as benchmarking fissure problems. In this study SIFs in relation to crack length were examined for edge and center cracked plates and results were compared with the theoretical values.

This study examines the impact of relaxation of Foreign Direct Investment (FDI) access on the trans-regional investment behavior of Indonesian enterprises. Utilizing data from publicly listed companies between 2010 and 2022, this study investigates how easing FDI restrictions influences the geographic distribution of subsidiaries. The findings indicate that FDI access relaxation significantly promotes trans-regional investment, driven by reduced government subsidies and lower market intervention. These mechanisms enable enterprises to expand beyond local markets by decreasing their dependency on government support and lowering their transaction costs. Robustness tests, including first-order difference models and dynamic distribution tests, confirmed the reliability of the results. This study suggests that a further reduction in FDI restrictions can enhance domestic market integration, mitigate capital market segmentation, and promote inclusive economic growth. This study contributes to the literature by providing empirical evidence of the economic benefits of FDI access policies and offers new strategies for addressing market segmentation in Indonesia.

This research examined the connections of efficiency, regulatory and good corporate governance (GCG) variables on the achievement or performance of financial aspects and social reporting from Indonesia’s Shariah banks generally. Data and samples collected in this research include 34 Shariah banks, which are administered in the central bank, Bank of Indonesia for the year of 2009 until 2022.
