The main goal of this research is to compare the various optimization strategies (Response Surface Methodology, Taguchi, and Teaching Learning Based Optimization) for orthogonal turning of Hard to Machine materials. The workpiece material in this work is Ti6Al4V alloys. After selecting cutting speeds in the High-Speed Machining range, orthogonal turning tests are performed on the material for a specific combination of machining parameters – Depth of Cut, Cutting Speed, and, Feed Rate. A Lathe Tool Dynamometer is used to record the cutting forces from the trials. After combining Johnson Cook Material and Damage models, a comprehensive Finite Element Model is created to model the Orthogonal Turning of Ti6Al4V alloys. Experiments conducted previously validate the developed model. Three different strategies, namely RSM, Taguchi, and TLBO, were used to optimise machining parameters for minimal Cutting Force. The approaches are compared for the best combination of machining parameters and the best Cutting Force value. Analysis of Variance is used to study the impact of machining factors on Cutting Force.

The main objective was to examine the impact of social norms, habits, and perceived behavioral control towards intention and its impact on energy-saving behavior. Also, the direct effects of habits and perceived behavioral control were examined towards energy-saving behavior. The target population was based on citizens of Saudi Arabia while the data collection was conducted using a quantitative approach. The purposive sampling was used, and data was analyzed using PLS-SEM using SmartPLS 3.2.8. The results show that habits had insignificant impact on energy-saving behavior. The habits had a significant impact on intention. The intention had an impact on energy-saving behavior. The perceived behavioral control had an impact on intention. The social norms had an impact on intention. We recommend that people should enhance their perceived behavioral control by believing on their attitude and feelings towards developing positive intentions that further leads towards energy saving behavior.

This article studies the mechanical characterization of impact loads on polyamide fibers. Using synthetic ropes in mooring systems, these are subject to static loads, but dynamic loads are also expected. One of the dynamic loads that can occur on cables are sudden loads, which makes the analysis of impact loads important. In this study, impact cycles were applied to polyamide multifilaments until rupture with different impact masses, and considering the conditions: dry, after 6 hours of immersion in water and after 24 hours of immersion in water. The analysis of the immersed conditions allows us to interpret the plasticizing effect that moisture exerts in polyamide, through loss stiffness in the rupture test. The results show that the increase in immersion time represents decrease in the breaking strength, and also in the resistance to impact cycles. A curve parameterization is proposed that relates the number of impact cycles and the percentage of Yarn Break Load used in the impact, getting through the coefficient of determination the best model. For force versus time graphs, obtained in each impact cycle, the energy dissipation in the multifilament can be observed in two main mechanisms: the first is the elastic deformation in form of ricochets, the second is the plastic deformation by stretching/elongation. The force-time graphs of impact cycles and the number of impact cycles to failure are measures that show performance for impact dynamic loads. Attention should be the plasticizing effect caused by water, as it reduces the static and dynamic mechanical strength of polyamide.

Halal food is food whose halal status is regulated by sharia institutions such as LPPOM MUI which is set by the government. The halal status of food must be traced from the process of raw materials, processing, packaging, transportation, and distribution to the final consumer. It is difficult to trace the certainty of halal food, especially beef in Medan City because the supply chain information from upstream to downstream is not transparent. To increase the transparency of beef status and increase consumer confidence, especially Muslim consumers, a distributed and transparent system is needed, where many parties can access the status of food at any time. So Blockchain technology is used to help track the halal status of beef along the supply chain. The purpose of this study is to design a system to obtain information certainty that beef distributed along the supply chain is halal and safe for consumption by utilizing Blockchain technology and to increase public safety and trust in the LPPOM MUI halal certification system. Based on the discussion and research analysis, it is known that the information in the halal beef supply chain in Medan City uses blockchain technology designed with a data security system using smart contracts, where information that has been stored cannot be changed by any party. so that there is a guarantee of information security in the beef supply chain in the city of Medan. This research is expected to support transparency, security, and certainty of information about halal beef in Medan City.

Ratcheting is a second failure mode in low cycle fatigue loading where plastic strain accumulates in each cycle. It is difficult to precisely estimate component deformation due to the complexities of cyclic hardening. In order to study the deformation, all types of hardening rules must be determined priorly. In this study, the determination procedures of combined hardening parameters are presented using Abaqus software. The experiment data of API-5L X80 from the past research have been utilized. Lastly, the different inputs of non-linear kinematic hardening choices are analyzed and presented.

With growing concerns about healthcare services especially during and after the Covid-19 pandemic, hospitals are compelled to provide non-traditional forms of quality services. Total quality management (TQM) practices are gaining attention and becoming a driving force to improve quality performance. This research aims to investigate the impact of TQM practices and quality performance in Jordanian public hospitals. The research used an online survey to collect data from 222 respondents from several public hospitals in Jordan. The results of structural equation modeling (SEM) confirms a positive relationship between supplier quality management, customer focus, and quality performance.

The article presents an analysis of the stress state of workpieces during upsetting of workpieces with an additional shear. For the analysis, the slip line method and the finite element method were used. A schematic diagram of upsetting in dies with “floating” elements, contributing to the implementation of additional shear, reduction of barreling, inhomogenous deformation and contour tensile stresses, is presented. The analysis of the research results showed that during upsetting of workpieces with additional shift forces, tensile stresses on the side surface of the workpieces decrease, which excludes the appearance of cracks on the side surface of the samples, especially when processing low-plastic alloy steels and alloys, and also reduces the barreling of the side surface.

In this study, Carbon, Glass, and Aramid fiber reinforced composite and their hybridized forms were fabricated using five different stacking sequences of the fabrics. Using the Vacuum Assisted Resin Transfer Molding (VARTM) procedure, epoxy resin was injected into these fabrics and allowed to cure at room temperature. From these five stacking sequences, a standard specimen with four different orientations viz. 0/90°, 15/75°, 30/60°, 45/-45° orientations were obtained using the Abrasive Water Jet Machining(AWJM) Process. The influence of stacking order and fiber orientation on tensile and flexural properties of composite was investigated. From the result of tensile testing, the highest and lowest tensile strength values were observed for neat carbon fiber reinforced composite at 0/90° orientation and at 45/-45° orientation respectively. The highest flexural strength was achieved in a hybrid combination of two layers of carbon, glass and aramid fabric for 0/90° whereas the lowest flexural strength was found in glass reinforced composite for the 45/-45° orientation.

This study aims to examine the effect of entrepreneurial strategy on organizational performance, the effect of social capital on organizational performance with sustainable supply chain management as a mediating variable. Sustainable supply chain management has an important influence on organizational measurement in various industries. It is used in considering environmental impacts and supplier responsibilities. The population in the current study were 390 logistics managers of companies in the manufacturing industry in Indonesia. The sample in this study was taken by purposive sampling, namely the sampling method based on certain criteria and considerations. In this study, hypothesis testing used the Partial Least Square (PLS) analysis technique with the SmartPLS 3.0 application. The data collection technique used is an online survey. The survey was carried out by distributing online questionnaires designed using the 1 to 7 Likert method to managers in the logistics section of the manufacturing industry. The stages of data analysis were to test convergent validity, discriminant validity test, goodness fit model test to meet the R-square value and test the hypothesis. The results show that entrepreneurial strategy and social capital had an influence on organizational performance and sustainable supply chain management. In addition, sustainable supply chain management mediates between organizational performance and entrepreneurial strategy, while social capital sustainable supply chain management does not mediate the organizational performance variables.
