Abstract

Background: Computers are the main devices that support the efficiency and effectiveness of work in modern office environments, including MSMEs in South Sumatra Province. However, long-term use of computers with unergonomic sitting postures can increase the risk of Work-Related Musculoskeletal Disorders (WMSDs) in workers. The results of preliminary observations showed that the percentage of variation in WMSD complaints was between 13%-42% of the total work-related diseases related to computers. Aim: This study aims to identify muscle complaints experienced by workers, analyze the risk of working posture using ergonomic methods, and provide suggestions for improvements to minimize the risk of musculoskeletal disorders. Methods: This study uses the Rapid Office Strain Assessment (ROSA) method to assess the risk of computerized and sitting activity-based work postures. In addition, Nordic Body Map was used to map the location of muscle complaints in respondents. The study was conducted on 20 workers in four MSMEs in South Sumatra Province who worked with high computer intensity. Results: The analysis showed that all four respondents had a high level of occupational posture risk based on the ROSA score. A total of 36 muscle complaints were reported, with the most complaints located in the lower neck, waist, and buttocks. The main factors causing complaints include prolonged static sitting positions and inadequate adjustment of work facilities. Conclusions: The work posture of MSME workers in South Sumatra Province indicates a level of ergonomic risks that requires serious attention. Interventions such as improving work facilities and training in correct work posture are highly recommended. Implementation. These findings affirm the importance of applying ergonomic principles in computer-based work environments to prevent WMSDs, improve work comfort, and support the productivity of government sector workers.

Abstract

Introduction/Main Objectives: The research examines how the structure of assets in Regional Government-Owned Enterprises (BUMDs) in Indonesia reflects their orientation in the sector they operate in. Background Problems: The paper addresses the problem of whether asset composition is significantly associated with business sectors and how such distribution patterns reveal the underlying public or commercial orientation of BUMDs in Indonesia. Novelty: This paper offers a novel empirical mapping of asset orientation using Correspondence Analysis, a method rarely applied in public sector financial research. Research Methods: A descriptive quantitative approach was utilized using secondary data from the report by Statistics Indonesia about BUMDs in 2023. The data were analyzed at the sectoral level of BUMD companies, originally expressed as percentage composition of four types of assets. The original percentage data were then converted into a contingency table format to be utilized for Correspondence Analysis and the Chi-square Test to determine the significance of the relation between various sectors and assets. Finding/Results: The study finds a statistically significant relationship between asset types and business sectors, with visual mappings showing that commercial sectors cluster around current assets while public-oriented sectors concentrate on fixed assets. Sectors such as finance, trade, and information emphasize liquidity, whereas construction and health prioritize infrastructure-heavy capital. Conclusion: Asset structures of BUMDs align with sectoral mandates and business orientations. These findings offer insights for regulators and enterprise managers to better align financial planning with institutional mission and to encourage the use of multivariate visual tools in public finance research.

Abstract

Background. PT Rentang Buana Niagamakmur is a spring mattress manufacturing company that faces a decrease in productivity due to worker discomfort and ergonomically suboptimal working postures Purpose. This study aims to identify the causes of workers' physical discomfort in the production process and design work aids that can improve comfort and productivity. Method. The research process began with data collection through observation and interviews to understand the activities of workers at the production station. The Nordic Body Map (NBM) was employed to identify workers’ musculoskeletal complaints, while Rapid Entire Body Assessment (REBA) was applied to evaluate ergonomic risk levels. Results. Based on the results of the analysis, the design of work aids was carried out using an ergonomic approach that suits the needs of workers at fabric measurement and foam cutting stations. Evaluation of the effectiveness of the aids was carried out by comparing REBA scores before and after the use of the aids. Conclusion. The results showed that the main physical complaints of workers were identified in the right wrist, waist, and calf. The design of work aids at the fabric measuring station lowered the REBA score from 11 to 3 (low risk), while the aids at the foam cutting station reduced the score from 7 to 3 (low risk). Implementation. The proposed work aids were shown to significantly reduce physical discomfort and improve productivity at both workstations.

Abstract

Background. Good audit quality reflects the level of confidence that the financial statements are free from material misstatement, whether caused by errors or fraud. When audit quality is low, for example, because auditors are not independent, tenure is too long without rotation, or the audit fee is too high, creating a conflict of interest, the risk of not detecting fraud increases. Aim. This study aims to reveal the strategic role of the audit committee in improving audit quality through analysing the relationship between fees, tenure, and auditor rotation on audit quality. With a quantitative approach and the aid of AMOS software, as well as Path Analysis techniques, this study aims to empirically map the structural relationship between these variables within the framework of governance and resource dependence. Methods. In conducting this research, the authors chose a research place in manufacturing companies listed on the Indonesia Stock Exchange for the period 2018-2021. In terms of type, this research uses a quantitative approach. Data in the form of numbers is collected through access to the Indonesia Stock Exchange website. This research uses descriptive and verification methods. The analysis technique employed is path analysis, utilizing AMOS (Analysis of Moment Structures) software. Result. Based on the results of model testing, it is found that only audit fees affect the audit committee. The absence of an effect of audit fees on audit quality in companies can be attributed to the level of professionalism of public accounting firms, which continue to maintain optimal audit quality, regardless of the amount of fees received. In contrast, the tenure and auditor rotation variables in this study did not show a significant effect on the audit committee, which indicates that these two variables may not yet be the main factors considered by the audit committee in their supervisory practices, or that their effects are more indirect and take longer to be observed. Conclusion. Based on the test results obtained, it is found that: (1) Only audit fees affect the audit committee, (2) Based on the regression test results, it is found that FA has a significant adverse effect on KOM_AUDIT with an estimate value of -0.090, standard error of 0.019, critical ratio of -4.729, and significance level of p < 0.001. This indicates that an increase in FA will lead to a decrease in the Audit Committee (3) In general, these findings confirm that in this model, the FA factor has an essential role in influencing the Audit Committee. At the same time, other aspects have not shown a significant relationship. This result implies that efforts to increase or change FA need more attention to improve or maintain audit quality. (4) In this study, it was found that audit fees affect the audit committee but have no effect on the audit quality of manufacturing companies. This result aligns with the principle of Resource Dependence Theory, where companies, through audit committees, seek to manage their relationships with external auditors as audit service providers to secure a crucial resource: quality audit services. Implementation. With the increasing complexity and risk of financial fraud, the results of this study are expected to make theoretical and practical contributions in encouraging the improvement of audit quality, strengthening audit committees, and developing more accountable corporate governance policies.

Abstract

Background, The production process at CV Natural is critical because the sales results of the product are to turn the wheels of the company's economy. The duration of production significantly affects the company because of the targets it must meet. In the production process of wooden carpets and various interior mat products from wood, there is much waste of wood raw materials, while if the wood is stored for too long, damage will occur. So, with this waste, there is a waste of storage costs on wood raw materials. Aim: This study aims to determine the application and role of Just In Time (JIT) in the efficiency of the company's production costs. Methods, JIT methods can streamline production costs without having to reduce product quality—determination of the optimal order quantity, applying JIT to the production line with the concept of line balancing. Results: The company's raw material inventory policy is not optimal and has not shown production cost efficiency compared to using the Economic Order Quantity (EOQ) method or the JIT method. Conclusions: if using the EOQ method, the company can save 63.89% or Rp. 113,473,933.41 of production costs, and if using the JIT method, the company can save 95.47% or Rp. 112,332,193.00 of the total inventory cost of Rp. 177,655,932.73. Implication, CV. Natural's JIT implementation has the potential to improve production cost efficiency significantly, provided it is managed with a solid supply chain management strategy and supported by adequate information systems. However, risk mitigation is required through strategic minimum buffers and close supplier relationships.

Abstract

Fraud in strategic sectors such as energy and finance, particularly within state-owned enterprises, remains a critical challenge to national economic integrity. Despite increased state revenues, the incidence of fraud continues to rise, highlighting the urgent need for robust technological interventions. This study aims to explore how Blockchain and Internet of Things (IoT) technologies have been utilized in anti-fraud systems over the past decade. Employing a Systematic Literature Review (SLR) approach guided by the PRISMA framework and conducted using the Watase Uake platform, this study analyzed 69 articles indexed in Scopus from 2015 to 2025. The analysis revealed a significant rise in research activity on this topic since 2019, peaking in 2022. The findings indicate that Blockchain’s decentralization and immutability, combined with IoT’s real-time monitoring capabilities, create a synergistic effect in enhancing fraud detection and prevention mechanisms. Empirical examples, such as fuel distribution frau d in Pertamina, illustrate how these technologies can reduce information asymmetry and improve audit quality. This study contributes to the literature by offering an integrated framework for leveraging emerging technologies in building transparent, secure, and efficient anti-fraud systems.

Abstract

Background, Manual waste management remains prevalent in community-based systems, particularly in developing countries, where limited mechanization and informal work practices elevate ergonomic risks. Despite the growing adoption of circular economy principles, ergonomic integration within waste management, especially in integrated farming systems, remains underexplored. Aim: This study investigates the application of ergonomic principles in the Joyful Integrated Farming System (J-IFS), a community- based model integrating waste sorting, composting, and agricultural production. Methods: A before-and-after ergonomic intervention design was implemented, combining anthropometric analysis, Rapid Entire Body Assessment (REBA), Nordic Body Map (NBM), time-motion study, and productivity measurement. Ergonomic interventions included workstation redesign based on worker anthropometry, improved manual handling tools, task rotation, and optimized work-rest cycles Results: The results show a 38% reduction in ergonomic risk levels, a 42% decrease in musculoskeletal discomfort, and a 27% improvement in operational productivity. Conclusions: The findings demonstrate that ergonomic integration not only reduces occupational health risks but also enhances work efficiency and system reliability. Implication. This study contributes empirical evidence supporting ergonomics as a strategic enabler of sustainable, labor-intensive waste management systems and extends applied ergonomics into the domain of circular, community-based operations.
