Strawberries are horticultural commodities that are highly susceptible to postharvest deterioration due to their high respiration rate, microbial activity, and oxidative degradation, resulting in a relatively short shelf life. This study aimed to evaluate the effectiveness of edible coatings in extending strawberry shelf life through a systematic literature review (SLR) approach. Literature was collected from several scientific databases using keywords related to edible coating, shelf life, and strawberry, covering publications from 2019–2026. From an initial 109 articles, a selection process based on inclusion and exclusion criteria resulted in 35 articles specifically discussing the application of edible coatings on strawberries. The synthesis results showed that all studies reported an extension of shelf life after edible coating application, although the effectiveness was influenced by the type of material, formulation, and storage conditions. Chitosan was the most widely used coating material due to its natural antimicrobial activity and excellent film-forming ability. The incorporation of bioactive compounds such as essential oils, plant extracts, and phenolic compounds was proven to enhance antifungal and antioxidant activities. In addition, nanotechnology-based systems demonstrated better preservation performance compared to conventional systems. However, methodological standardization and industrial-scale validation are still required to support commercial implementation.

Predictive maintenance (PdM) plays a crucial role in modern industrial systems by minimizing downtime, reducing maintenance costs, and optimizing asset performance. However, many predictive models operate as “black box” systems, limiting transparency and making it difficult for operators to interpret their outputs. This study aims to integrate Explainable Artificial Intelligence (XAI) techniques with Remaining Useful Life (RUL) prediction models to improve both accuracy and interpretability. Various machine learning and deep learning approaches, including Support Vector Machines (SVM), Random Forest (RF), XGBoost, Long Short-Term Memory (LSTM), and Convolutional Neural Networks (CNN), are employed to predict RUL using real-time sensor data from rotating machinery. XAI methods such as SHAP, LIME, and attention mechanisms are applied to provide human-understandable explanations of model predictions. The models are evaluated based on accuracy, Root Mean Square Error (RMSE), and interpretability scores. The results show that XAI-enhanced models outperform traditional approaches in predictive performance while offering greater transparency. These explanations help maintenance engineers better understand the factors influencing predictions, thereby improving decision-making and trust in the system. Nevertheless, the integration of XAI introduces additional computational complexity, which may pose challenges for large-scale industrial implementation. Overall, this study highlights the potential of combining XAI with RUL prediction to develop more reliable, transparent, and effective predictive maintenance solutions.

ABSTRACT There must be a fair and balanced application of the legal rights and responsibilities that arise from the employment relationship between employers and employees. Employers' continued activities of withholding diplomas from workers, even after the employment relationship has ended, may have negative consequences for workers and limit their ability to find new career possibilities. The purpose of this research is to examine the employment agreement's provisions on the parties' respective roles and responsibilities in the workplace, and to determine whether or not employees have any recourse if their employers choose to retain their diplomas even after the job relationship has ended. Normative legal research using conceptual, factual, and regulatory approaches is the study technique used. Holding workers' diplomas is illegal, violates their human rights, and goes against labor laws and regulations, according to the report. Legislation protects employees both preemptively, via government oversight and normative regulation, and punitively, via processes for resolving disputes in industrial relations and the imposition of administrative, civil, and criminal penalties. Companies cannot legitimately withhold diplomas; thus, this practice must end in order to provide legal clarity and respect for workers' dignity. Keywords : Legal Protection, Workers, Diploma.

Global economic uncertainty and exchange rate fluctuations pose significant challenges to monetary stability in Indonesia, particularly in maintaining a controlled inflation rate. This study aims to analyze the transmission mechanism of the rupiah exchange rate to the inflation rate in Indonesia from 2015 to 2024. The method used in this study is library research by collecting, reviewing, and synthesizing data from various scientific literature, official central bank reports, and related journal articles published over the past decade. The research findings indicate that rupiah depreciation has a significant influence on rising inflation through the imported inflation channel, where currency depreciation increases the cost of raw materials for industries dependent on foreign markets. Furthermore, the findings reveal that the effectiveness of this transmission is influenced by public expectations and monetary policy taken by Bank Indonesia through adjustments to the benchmark interest rate. The implications of this study emphasize the importance of synergy between a stable exchange rate policy and controlling the supply of domestic goods to minimize the impact of external shocks on public purchasing power. The government and monetary authorities are advised to continue strengthening foreign exchange reserves and encouraging the use of local currencies in international transactions to reduce dependence on the United States dollar and maintain national price stability.

This study aims to analyze the effect of work stress and work environment on employee performance with job satisfaction as a mediating variable at PT X. This study uses a quantitative approach with a census method of 198 employees at PT X. Data were collected through an online questionnaire (Google Form) and analyzed using Structural Equation Modeling based on Partial Least Square (SEM-PLS) with the help of SmartPLS 4.0. Based on the results of the analysis that has been done, it was found that work stress has a negative and significant effect on employee performance. Meanwhile, the work environment has a positive and significant effect on employee performance. In addition, work stress has a negative and significant effect on job satisfaction. Then, the work environment has a positive and significant effect on job satisfaction, while job satisfaction has a significant effect on employee performance. In addition, job satisfaction is able to mediate the effect of work stress and work environment on employee performance. This study provides a theoretical contribution to strengthen the understanding of the role of job satisfaction as an important mechanism that connects work stress and work environment with employee performance. Management needs to manage work stress through a balanced workload and system arrangement and create a safe and comfortable work environment to improve employee satisfaction and performance. These findings underscore the importance of job satisfaction as a basis for formulating human resource policies. This study is limited by the number of respondents, which is not fully representative of the entire population due to difficulties in communicating with employees. Furthermore, limited access to the research location, which is located outside of Yogyakarta, resulted in the distribution and collection of questionnaires being conducted only through long-distance communication. Future researchers are advised to add other variables and use research subjects from different industrial sectors to obtain a more comprehensive and comparable understanding.

Exposure to toxic materials in the workplace remains a major occupational health and safety issue, particularly in industrial sectors with high chemical use intensity. Various control efforts have been implemented through industrial hygiene and occupational safety (OHS) programs, but their effectiveness varies. This study aims to analyze strategies for controlling toxic material exposure through industrial hygiene and OHS programs based on literature review over the past five years. The method used was literature review of 10 national journals relevant  the topic of toxic material exposure in various industrial sectors. The analysis results indicate that toxic material exposure is still found in various sectors, with types of materials such as heavy metals, organic solvents, toxic gases, and industrial dust. The most commonly implemented control strategies are the use personal protective equipment (PPE), administrative controls, and some engineering controls such as ventilation. However, the effectiveness of these controls is less than optimal due low worker compliance, limited supervision, and the minimal implementation of higher-level controls such as elimination and substitution. Therefore, it is necessary to strengthen integrated industrial hygiene programs, improve worker compliance, and implement a more comprehensive hierarchy of controls to minimize the risk of toxic material exposure in the workplace.

This study uses a quantitative method with an explanatory approach to explore factors contributing to low pension literacy among workers. The sample consisted of 66 workers from both the formal and informal sectors in Jakarta in December 2025. The findings reveal that low pension literacy is not solely due to a lack of knowledge but results from various factors, including low awareness, short-term financial behavior, product complexity, inadequate education, and underutilization of digital tools. There is a mismatch between workers' perceptions and the reality of pension fund behavior. The majority of workers (86%) are unprepared for retirement, and 89% do not have a voluntary pension fund. Despite this, 80% do not rely on workplace pension funds, and 45.5% feel confident they can meet their living expenses in old age, indicating pseudo-awareness they understand the importance of pension funds but have not established one. This reveals a gap between awareness and action regarding pension funds. Improving pension literacy requires an integrated approach that combines transformative education with digitalization to facilitate access and participation. Education must drive behavioral change, while digitalization simplifies processes, enhances accessibility, and broadens financial literacy. The synergy of education, digital technology, and policy support is essential for improving workers' financial readiness for a secure retirement.

This research addresses a paradoxical phenomenon in Lampung Province's Micro and Small Industry (MSI) sector (2018-2022), where high technology adoption is accompanied by declining business units and income inequality. The objective is to evaluate technical efficiency and productivity changes across 15 regencies/cities using the Variable Returns to Scale (VRS) Data Envelopment Analysis (DEA) model and the Malmquist Productivity Index (MPI). Results show an average technical efficiency of 0.838, indicating a 16.2% room for output improvement. Mesuji Regency serves as the benchmark with perfect efficiency. The main inefficiency stems from labor slack (averaging 3,458 people per region), reflecting disguised unemployment. The Malmquist index records an asymmetric productivity growth of 2.1% annually, entirely driven by technological progress (3.5%), while internal managerial efficiency contracted (-1.4%). Consequently, technology adoption requires structural intervention; regional governments must prioritize vocational training and basic managerial strengthening to reduce labor slack and break the MSI inefficiency cycle.

Prodeo legal aid is one of the ways in which the state fulfils its responsibility to guarantee access to justice for economically disadvantaged members of the public. However, its implementation still faces challenges, particularly budgetary constraints, meaning that not all applications for prodeo legal aid can be processed. This issue arises in Industrial Relations Court (PHI) cases at the Banjarmasin District Court. This study aims to examine the implementation of prodeo services in PHI cases and to analyse these budgetary constraints from a constitutional law perspective. The methodology employed is a normative legal approach with an empirical focus, utilising a review of legislation, interviews, observations, and a literature review. The research findings indicate that prodeo is a service for litigation at no cost, funded by the state through the State Budget Allocation (DIPA). In 2025, a budget of Rp. 33,728,000 was only sufficient to handle 13 cases, meaning the service depends on the availability of funds. This situation reflects a gap between the constitutional guarantee of access to justice and practice on the ground. Therefore, improvements are needed in budget planning, allocation, and management, as well as the strengthening of the role of Legal Aid Posts and Legal Aid Institutions to enhance access to justice for the underprivileged.

Human activities, from household to industrial operations, generate liquid waste that poses a threat to the environment. Before discharge, liquid waste should be treated to ensure it is safe for release into the environment. This study aims to evaluate the effectiveness of a hybrid ozonation-adsorption method with varying contact times. This study collected leachate samples from the Rajabasa Landfill and used fly ash from the Tarahan Coal-Fired Power Plant as the adsorbent. First, the study used contact times of 20, 40, 60, and 80 minutes for ozonation. Subsequently, the 80-minute sample proceeded to the adsorption stage and was ultimately tested against six parameters. The measured parameters included COD, TSS, TDS, turbidity, UV254, and DO. The results showed that the 80-minute ozonation process significantly reduced TSS, TDS, and DO levels. However, the ozonation process still left intermediate compounds, which were subsequently removed by adsorption. Ultimately, the combination of the two processes yields good results, particularly for COD and UV254. This aligns with the theory that ozonation breaks down complex compounds while the adsorbent absorbs residual pollutants. This hybrid process achieves a 45.47% reduction in COD and an 87.83% reduction in UV254.

Presidential Regulation Number 10 of 2021 on Investment Business Fields introduces a fundamental transformation in Indonesia’s investment regulatory regime by replacing the previous negative list approach with a positive list system. This regulatory shift significantly affects the structure of investment liberalization, particularly in the industrial sector, which serves as the backbone of the national economy. This study aims to analyze the regulatory changes introduced by Presidential Regulation 10/2021 and examine their juridical and practical implications for the investment climate and industrial business actors. Using a normative juridical method through the analysis of legislation, policy documents, and academic literature, this research finds that the regulation enhances investment openness, expands foreign ownership, simplifies risk-based licensing, and strengthens legal certainty through the classification of priority business fields, mandatory partnerships with cooperatives/MSMEs, and conditioned business categories. However, its implementation still faces challenges, including the harmonization of sectoral regulations, regulatory–political dynamics, and the government’s supervisory capacity. Overall, Presidential Regulation 10/2021 has the potential to strengthen the attractiveness of the industrial sector and its integration into global value chains, yet its effectiveness strongly depends on consistent implementation and cross-sector policy alignment.   Keywords: Presidential Regulation 10/2021, investment regulation, investment liberalization, industrial sector, investment policy.

The Low Voltage Main Distribution Panel (LVMDP) is a critical component in industrial power distribution systems, functioning to regulate, control, and distribute electrical energy to various production equipment. During operation, LVMDP panels often operate under high electrical loads, which may lead to temperature increases in their components. Undetected temperature rise can result in performance degradation, equipment failure, and even fire hazards. Therefore, an effective monitoring method is required to detect the condition of electrical components at an early stage. This study aims to analyze the temperature difference (ΔT) of LVMDP components using the Infrared Thermography method as part of predictive maintenance. The research employs a quantitative descriptive approach with data collected through direct observation from July 1 to July 31 at PT. Dongjin Indonesia. The data consist of hotspot and ambient temperatures measured from several panel components, which are then analyzed to calculate the temperature difference (ΔT) as an indicator of component operating conditions. The results indicate that the highest temperature difference is 26.5 °C in the capacitor bank, while the lowest is 4 °C in other components. All ΔT values are below the threshold limit of 50 °C, indicating that the LVMDP components are in safe operating conditions and do not require corrective actions. Thus, Infrared Thermography is proven to be an effective method for early detection of component conditions and can enhance the reliability and safety of industrial power distribution systems.
