Industrial visits are widely recognized as an experiential learning approach that bridges the gap between theoretical knowledge and real industrial practices in engineering education. This study aims to examine the relationship between industrial visits and the improvement of production system understanding and critical thinking skills among students of the Faculty of Industrial Technology at Universitas Nahdlatul Ulama Al-Ghazali (UNUGHA) Cilacap. A quantitative approach with a one-group pretest–posttest design was employed. The participants consisted of 43 industrial engineering students who took part in industrial visits to PT Dirgantara Indonesia and the National Research and Innovation Agency (BRIN) in Bandung. Data were collected using Likert-scale questionnaires and analyzed through Paired Sample t-Test. The results reveal a significant increase in students’ understanding of production systems, with mean scores rising from 64.23 (pretest) to 81.47 (posttest) (p < 0.05). Similarly, critical thinking skills showed a significant improvement, increasing from a mean score of 63.05 to 83.12 (p < 0.05). These findings demonstrate that industrial visits have a substantial positive impact on enhancing students’ academic competencies. This study highlights the importance of systematically integrating industrial visits into the industrial engineering curriculum to strengthen learning outcomes and improve graduates’ readiness for industrial challenges.

Oil palm plantations constitute a leading subsector that plays a strategic role in regional economic development, particularly in Nagan Raya Regency, which is predominantly based on the agricultural sector. This study aims to analyze the role of the oil palm plantation subsector in promoting regional economic development using the Economic Base Theory as an analytical approach. A descriptive qualitative method with a literature study was employed. The data used consist of longitudinal secondary data for the period 2019–2024, sourced from official publications of Statistics Indonesia, regional development planning documents, and relevant scientific articles. The results show that the agricultural sector, dominated by the oil palm plantation subsector, makes a large and relatively stable contribution to the Gross Regional Domestic Product (GRDP) of Nagan Raya Regency, thereby qualifying it as a basic sector. This subsector also plays an important role in employment absorption, particularly in rural areas. However, the substantial economic contribution and labor absorption have not been fully accompanied by equitable improvements in community welfare, as indicated by the relatively slow decline in poverty rates. This condition suggests that the economic multiplier effect of the oil palm plantation subsector has not yet been optimal due to limited downstream activities and low value-added processing at the regional level. The study concludes that strengthening downstream industries and intersectoral linkages is necessary to ensure that the role of oil palm plantations can more effectively support inclusive and sustainable regional economic development.

This article explores inconsistencies in employee performance within small, project-oriented service sectors, where quality depends on daily tasks, punctuality, and adherence to procedures. Since skill development relies largely on informal workplace learning, differences in worker competencies often lead to rework, customer complaints, and safety issues. The study investigates how skills and competencies affect employee performance, illustrating how individual abilities translate into observable performance through the ability–motivation–opportunity (AMO) framework and experience-based learning. A qualitative case study at Rajasa Teknik included interviews and observations to examine project coordination, quality standards, and supervision practices. Results indicate that competencies and skills primarily influence ability, but sustained motivation- driven by realistic goals and fair feedback- along with ample opportunities such as smooth material flow, clear roles, and on-site decision support, enhance performance. The findings underline the importance of a cohesive work system (task division, quality control, communication), a consistent safety culture (K3), and straightforward, repetitive HR practices that facilitate tacit knowledge transfer into routines. Improvements suggested involve mapping core competencies, brief mentoring sessions, quality-focused standards, and evaluation systems to minimise service variation and promote sustainable performance in similar businesses. Overall, this research broadens the understanding of performance management in small enterprises and offers practical guidance for interventions.

This study investigates the determinants of dividend payout policy in energy sector firms listed on the Indonesia Stock Exchange during the 2020–2024 period. Dividend policy is a critical issue in emerging markets, especially in capital-intensive industries with high investment needs and earnings volatility. The research examines whether profitability and ownership structure—specifically institutional and managerial ownership—significantly influence dividend payout decisions, considering firm characteristics. The study analyzes the effect of profitability, institutional ownership, and managerial ownership on the dividend payout ratio, while controlling for firm size and leverage. A quantitative approach is used, employing pooled ordinary least squares (OLS) regression on 245 firm-year observations. Dividend payout ratio is measured as dividend per share divided by earnings per share, profitability is proxied by return on equity, and ownership variables are expressed as shareholding proportions. Descriptive analysis and classical assumption tests precede hypothesis testing. The results show that profitability positively and significantly affects dividend payout, suggesting that firms with better financial performance tend to distribute higher dividends. Firm size also positively influences dividend policy, while leverage negatively impacts it, reflecting the role of financial capacity and capital structure. However, institutional and managerial ownership do not show significant effects on dividend payout decisions. The findings indicate that dividend policy in Indonesian energy firms is primarily driven by financial performance and structural characteristics rather than ownership-based governance mechanisms. This study offers sector-specific evidence that refines agency and signaling perspectives on dividend policy in emerging markets, with practical implications for managers, investors, and regulators.

Workplace microaggressions represent subtle and ambiguous forms of interpersonal mistreatment that are frequently normalized in organizational interactions, yet may generate significant psychological consequences for employees. While research in industrial and organizational psychology has extensively examined related constructs such as workplace incivility and ostracism, the linguistic mechanisms through which microaggressions operate remain underexplored. This study aims to systematically review Indonesian-language journal articles published between 2015 and 2025 that address workplace microaggressions and related phenomena, by conceptualizing microaggressions as speech acts. Using a systematic literature review approach guided by the PRISMA 2020 framework, relevant peer-reviewed articles were identified, screened, and analyzed through thematic synthesis. The review focuses on three main aspects: linguistic forms of microaggressions, contexts in which they emerge, and their psychological consequences in formal organizational settings, including companies and educational institutions. The findings indicate that workplace microaggressions are predominantly realized through indirect and ambiguous communicative practices, such as dismissive remarks, stereotypical humor, and interactional exclusion, often occurring within hierarchical relationships and formal work situations. These communicative acts are consistently associated with negative psychological outcomes, including stress, emotional exhaustion, reduced wellbeing, and withdrawal-related work attitudes. By integrating industrial-organizational psychology with linguistic-pragmatic perspectives, this review highlights language as a central mechanism through which microaggressions produce psychological harm at work. The study contributes a conceptual synthesis that underscores the importance of addressing everyday communicative practices in organizational interventions aimed at fostering psychological safety and employee wellbeing.

In article 157A of Law Number 6 of 2023 that in the process of termination of employment, employers and permanent workers must carry out their respective obligations, employers can carry out suspension actions and still pay wages and other rights, but in reality employers rarely apply article 157A. The purpose of the research is to analyze the Implementation, Obstacles and Efforts on Workers' Rights in Wage Payment During the Termination of Employment Process at Palm Oil Company in Siak Regency. This type of research is Sociological legal research. In this research, three approaches are used, namely the legislative approach and the data source case approach using primary data and secondary data. The data collection technique used is primary data through interviews and questionnaires. The conclusion of this study is the legal protection of workers' rights during the termination of employment by the company through the settlement of industrial relations disputes in which there are various interpretations regarding the wage process. Article 157A of Law Number 6 of 2023 states that the responsibility of employers and workers remains valid until the industrial relations dispute settlement agency makes a decision. The implementation in the process of termination of employment is that workers are no longer allowed to work by the company but do not carry out suspension actions, but there are many companies that do not carry out things regulated by law. With the existence of multi-interpretation regulations on wages, the process provides uncertainty for workers, as well as in the interim decision submitted by the worker/plaintiff which is rejected by the judge which is clear that the worker can prove that the employer does not carry out his obligations as it should.

The research employs a qualitative descriptive approach through literature review and analysis of regulations, policies, and the role of metrological institutions in supervising product quality. The discussion focuses on compliance with standards, supervisory mechanisms, and the responsibility of business actors as key elements of consumer protection. The findings indicate that qualitative improvement of product quality contributes to fair transactions, enhances consumer trust, and prevents practices that may harm consumers. This study is expected to serve as a reference for relevant institutions in strengthening the role of metrology as an integral part of the consumer protection system.

The foundation of turbine machines in industrial buildings must be able to withstand static and dynamic loads caused by operational vibrations. Generally, reinforced concrete block foundations are used due to their good stability. However, under certain conditions such as limited land, decreased soil bearing capacity, and the need for structural rehabilitation, their application becomes less effective. Therefore, this study aims to analyze the use of Micropile foundations as an alternative for turbine machine foundations at Candi Baru Sugar Factory, Sidoarjo.The research method includes literature studies, soil data collection through Cone Penetration Test (CPT), machine technical data analysis, and the design and analysis of Micropile foundations. The analysis covers bearing capacity, settlement, dynamic response, pile cap design, and cost estimation.The results indicate that Micropiles with a diameter of 0.20 m, a length of 2 m, five piles, and a pile cap size of 2 m × 2 m × 4.5 m are able to safely and stably support the machine load. In addition, this system is considered more efficient in terms of construction time and implementation. Therefore, Micropile foundations are recommended as an effective and economical alternative for turbine machine foundations.

Lifting activities are an essential part of manual material handling across various industrial sectors and constitute a primary source of ergonomic risk exposure when performed with inappropriate work postures. The use of hands-off tools such as push-pull sticks is often implemented to maintain a safe distance between workers and loads and to reduce exposure to line-of-fire hazards. However, the implementation of work aids does not automatically ensure neutral work postures, as push-pull techniques, reach distances, and environmental conditions can still lead to awkward postures. This study aims to evaluate the work posture risk in lifting activities using a fiber-composite push-pull stick based on the Rapid Entire Body Assessment (REBA) method. The research was conducted as an observational analytic field study involving nine workers in tubular pushing and pulling activities. Work postures were documented through direct observation and visual recordings, then assessed using REBA to obtain risk scores, risk categories, and required corrective actions. The results indicate that work postures fall into the medium to high-risk categories, with trunk and shoulder components being the dominant contributors. These findings confirm the need for improvements in work methods, ergonomic training, and strengthening of lifting SOPs to optimize the safety and ergonomic benefits of work aids.

Students of vocational high schools are required to write an internship report as a form of accountability for completing their industrial training. However, various language errors are still found in students’ PKL reports. This study aims to describe and analyze morphological errors in the PKL reports of vocational high school students majoring in Electronics Engineering. The study employed a descriptive qualitative approach using document analysis. A total of 223 PKL reports were written by all students of SMK Negeri 3 Yogyakarta in 2025. The research data consisted of 25 PKL reports from students of the Electronics Engineering major selected through purposive sampling. Data analysis was carried out through the stages of identification, classification, description, quantification, and interpretation of morphological errors, with data validity ensured through theoretical triangulation. The results show that 286 morphological errors were identified, consisting of prefix errors (96), suffix errors (52), confix errors (41), reduplication errors (28), compound word errors (34), and base-form errors (35). Prefix errors were the most dominant type, accounting for 33.6% of all errors. These findings indicate that students still experience difficulties in applying affixation rules and forming standard words in formal written language. Such errors are influenced by interference from spoken language and the technical language used in the workplace. This study highlights the importance of structured and contextual morphology instruction to improve the quality of vocational students’ PKL report writing.

This study aims to analyze the transformative impact of digitalization and technology in the manufacturing sector on improving operational efficiency, particularly in budgeting and resource utilization, as well as to identify the main barriers to technology adoption. Using a Literature Review and Case Study Analysis of secondary data (journals, company reports, and industry publications), it was found that digitalization and Automation supported by Artificial Intelligence (AI) fundamentally transform budgeting functions. This transformation has been shown to improve budget accuracy by up to 50% (reducing human errors) and process efficiency by up to 25%, turning budgets from static documents into adaptive and predictive control tools. Positive impacts are also observed in operations through increased production capacity (revenue surge) and the implementation of Predictive Maintenance, which reduces expenditure and asset downtime, in line with the principles Cost Efficiency and Lean Manufacturing. Nevertheless, the adoption of advanced technology faces significant obstacles, namely high initial capital investment and skill gaps among the workforce. It is concluded that the success of digitalization heavily depends on strategic budget planning to overcome capital barriers and adequate allocation of funds for Human Resource (HR) training to support effective collaboration between humans and machines.
