Abstract

The purpose of this study was to determine the relationship between the position of shielded metal arc welding (SMAW) with spiral motion V on the tensile strength and microstructure of low carbon steel. The research was conducted by welding V-coated low carbon steel with horizontal 2G, vertical 3G and overhead 4G. The test results show that the welding position does not have a significant effect on the tensile strength of low carbon steel welds, where the 3G vertical position provides a higher tensile strength value than the 2G horizontal position and 4G overhead. The microstructure of acicular ferrite (AF) in the vertical position looks dominant uniformly and tightly.

Abstract

This study's objective is to review the consequence of the COVID-19 epidemic on physical activities, sedentary lifestyles, screen time, and changes in the nutritional status of school-age children. The outcomes of this study are intended to be applicable to obesity management in children. This study reviewed full-text articles and open-access publications on the sedentary lifestyle of children during the pandemic. and the data were analyzed using cohort, case-control, and cross-sectional designs. The results of reviewing 17 articles show that school-age children’s physical activities and nutritional status have decreased, but their sedentary lifestyle and screen time have increased due to social restrictions during the COVID-19 pandemic. Children’s decreased physical activities are caused by the absence of a comparable replacement mechanism as that before the pandemic. Meanwhile, the increasingly sedentary lifestyle highly influences children’s physical and mental health. Screen time has also increased and is unavoidable during the pandemic because children’s activities were limited and their learning systems are switched to online learning; as a result, their supporting sedentary lifestyle increases while physical activities decrease. These factors have changed the nutritional status of children during the pandemic. These results support the idea that the pandemic will impact the health of school-age children, especially their nutritional status. This review concludes that it is important to establish policies that prevent children’s further health effects, such as obesity, caused by COVID-19.

Abstract

This study explores the adaptation of statistical thinking in traditional manufacturing contexts, emphasizing its significance as a cognitive and cultural framework for improving quality, reducing process variation, and fostering data-informed decision-making. While statistical thinking has become a cornerstone in modern manufacturing systems, its integration into traditional environments—dominated by legacy processes, experiential judgment, and minimal technological infrastructure—remains limited. The purpose of this research is to analyze the current landscape of statistical awareness in such settings and to identify both enablers and barriers to its broader adoption. Employing a qualitative methodology based on an integrative literature review, this study synthesizes evidence from peer-reviewed articles, industry case studies, and theoretical frameworks published between 2000 and 2024. Thematic analysis reveals a persistent gap in statistical literacy among employees, cultural resistance among leaders, and technological limitations that impede implementation. However, emerging practices—such as contextualized training, policy interventions, and leadership-driven cultural change—offer promising pathways for sustainable integration. The findings contribute to both academic and managerial discourse by reframing statistical thinking as a holistic organizational capability rather than a technical function. This research advocates for a strategic and inclusive approach that combines education, infrastructure, and leadership to foster statistical maturity in resource-constrained manufacturing environments. In doing so, it supports long-term resilience, continuous improvement, and competitiveness in the face of global industrial transformation.

Abstract

This study examines the influence of digital transformation, innovation capability, social media marketing, and market turbulence on marketing performance among creative economy players in Malang City. It also analyzes the mediating role of social media marketing in the relationship between digital transformation and innovation capability with marketing performance, as well as the moderating role of market turbulence in the relationship between social media marketing and marketing performance.The study adopts a quantitative approach with a cross-sectional design. The population consists of 4,951 creative economy business players in Malang City, with a sample of 196 respondents determined using the Slovin formula. Data were collected through questionnaires and analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) with SmartPLS software, including descriptive analysis, validity and reliability testing, and hypothesis testing through bootstrapping.The results indicate that digital transformation has a significant positive effect on marketing performance, while innovation capability does not. Digital transformation and innovation capability significantly improve social media marketing, which in turn has a significant positive effect on marketing performance. Market turbulence has a significant negative effect on marketing performance and significantly moderates the relationship between social media marketing and marketing performance. Social media marketing significantly mediates the effects of digital transformation and innovation capability on marketing performance.

Abstract

This study aims to determine students' perceptions of History teaching in grade XI of SMA Negeri 1 Parigi Tengah, specifically regarding the teaching methods used by teachers with a background in Geography. This study uses a descriptive qualitative approach conducted in a natural setting. The research subjects consisted of grade XI students, with supporting informants in the form of subject teachers and homeroom teachers. Data collection techniques were carried out through observation, semi-structured interviews, and documentation. Data were analyzed using an interactive analysis model that includes data reduction, data presentation, and drawing conclusions. The results of the study indicate that students' perceptions of History teachers' teaching methods vary. Some students considered the lecture method used to help understanding the material if delivered clearly, coherently, and communicatively. However, some other students felt that the method was less interesting if it was done monotonously and with minimal variation, thus decreasing interest and active learning. The use of learning media was also considered suboptimal, even though supporting facilities were available at the school. Factors that influence students' perceptions include the teacher's ability to deliver the material, the teacher's teaching style and attitude, the suitability of the method to the characteristics of the History material, students' interests and learning styles, and the learning environment. This study concludes that variations in methods and the use of learning media are very necessary to increase students' interest and understanding in learning History.

Abstract

This study aims to describe the pedagogical knowledge and skills of history teachers at MTs Al-Khairaat Kalukubula and identify factors that support and hinder their implementation. Pedagogical competence is a teacher's ability to understand students, design and implement learning, provide learning outcomes, and develop students' potential to achieve optimal learning objectives. This study used a qualitative descriptive approach with data collection techniques including interviews, observation, and documentation. The research subjects included history teachers, the principal, and students at MTs Al-Khairaat Kalukubula. The results indicate that historical teachers understand student characteristics and systematically plan learning through tools such as syllabi, lesson plans, annual programs (Prota), and semester programs (Promes). Learning progressed quite well, despite challenges such as limited media, infrastructure, and limited teaching staff. Learning outcomes were evaluated through assignments, daily tests, mid-term exams, and remedial classes for students who have not yet met the Minimum Completion Criteria (KKM). In general, the pedagogical competence of history teachers at MTs Al-Khairaat Kalukubula has been quite good, demonstrated by their ability to manage educational, communicative, and reflective learning. However, improvements are needed in the areas of method variation, the use of digital learning media, and more optimal implementation time.

Abstract

Micro, Small, and Medium Enterprises (MSMEs) entrepreneurs still focus on trading and forget the potential side of intellectual property rights, this is due to ignorance, ego, or closed nature of business actors about new ideas and entrepreneurs feel quickly satisfied with their achievements. In product marketing communications, one of the functions of intellectual property rights is as a means for cultivating a positive image in the minds of consumers, so this needs to be understood by business actors, because the benefits of intellectual property rights for products are one of the important points so that MSME agricultural products are always remembered by the public or consumers who have tried the product for a period of time and have added value from the product. In this community service activity, a presentation was carried out, and to measure quantitatively the increase in knowledge, a pretest and posttest were conducted. The results of the increase in knowledge were an increase of 39% from the posttest results for community service participants.
