Seren Village has abundant organic waste potential, particularly banana peel waste generated from banana-processing MSME activities and wood ash resulting from household firewood combustion. To date, this waste has not been optimally utilized and is often discarded, thereby posing potential environmental problems. This study aims to process banana peel waste and wood ash into an innovative, environmentally friendly shoe polish made from natural materials, while also enhancing the economic value and welfare of the community. The research employed a descriptive qualitative method with a case study approach. Data were collected through observation, interviews, and documentation involving the women’s Family Welfare Empowerment Group (PKK) of Seren Village as the target participants. The shoe polish production process includes drying and grinding banana peels, mixing them with a wood ash solution that functions as a natural coloring agent, adding supporting materials, and heating the mixture until a ready-to-use shoe polish is obtained. The results indicate that the shoe polish produced from banana peels and wood ash has a solid texture, is slightly coarse, non-glossy, and has a relatively fast drying time of approximately one minute. In addition, the product shows good resistance to water splashes and does not damage the surface of shoes. The use of natural ingredients makes this shoe polish safer for health. The utilization of this waste has the potential to support MSME development, reduce environmental pollution, and sustainably improve the welfare of the Seren Village community.

This study aims to develop a strategic plan for Information Systems and Information Technology (IS/IT) at KR Hotel Palembang by applying the Ward and Peppard methodology. The analysis began with external environment assessment using the PEST framework and internal analysis through the MOST method and Value Chain model. The results were synthesized into a SWOT analysis to identify the organization's strengths, weaknesses, opportunities, and threats. From this, Critical Success Factors (CSF) were formulated to guide the determination of key information system needs. Application portfolio mapping was then conducted using the McFarlan Strategic Grid to classify systems based on their strategic impact. Findings indicate that KR Hotel has strong potential in leveraging digital technologies but faces challenges such as the absence of integrated systems across departments and limited IT training for staff. To address these issues, an integrated system named ZKBiolock was proposed, encompassing modules such as hotel management, financial management, customer relationship management (CRM), human resource training systems, digital promotion, and internal network monitoring and control. This strategic plan is supported by a comprehensive database design, network topology, human resource and infrastructure analysis, investment budgeting, and Return on Investment (ROI) evaluation. The proposed strategy aims to enhance the efficiency and effectiveness of the hotel's operational management.

This study aims to analyze the representation of the five stages of grief in the film 172 Days through a literary psychology analysis. This film is of particular interest because it is an Indonesian box office hit based on a true story that portrays both emotional and religious experiences of loss. The study employs a qualitative descriptive approach, with the objects of analysis being visual scenes and the dialogue of the character Zira that represent the experience of grief. Data were collected through systematic observation of the film and a review of relevant literature on grief theory. Data analysis was conducted using content analysis techniques, classifying scenes based on the stages of grief according to Elisabeth Kübler-Ross: denial, bargaining, anger, depression, and acceptance. The results indicate that the film represents the five stages of grief progressively through the main character’s emotional journey. The denial stage is evident through the denial of the illness’s condition; bargaining through prayer as a form of spiritual negotiation; anger through emotional outbursts following the loss; depression through deep sorrow and attachment to memories; and acceptance through embracing the loss and finding new meaning in life. These findings indicate that the film functions not only as a medium of entertainment but also as a psychological representation of the grieving process that is universal and reflective for the audience.

The integration of Artificial Intelligence (AI) into precision agriculture has significantly improved plant disease recognition; however, many existing deep learning models remain computationally expensive and feature-redundant, limiting their deployment on low-power and edge devices. To address these limitations, this study proposes a lightweight framework for maize leaf disease recognition based on serial deep feature extraction, dimensionality reduction, and machine-learning–based classification. A pre-trained MobileNetV2 network is employed as a fixed feature extractor to obtain discriminative visual representations, while Principal Component Analysis (PCA) is applied to reduce feature dimensionality by approximately 76%, retaining 95% of the original variance and improving computational efficiency. The compressed features are subsequently classified using a Radial Basis Function Support Vector Machine (RBF-SVM), optimized via grid search and cross-validation. Experiments conducted on a four-class maize leaf disease dataset (Northern Leaf Blight, Common Rust, Gray Leaf Spot, and Healthy), with class imbalance handled during training, demonstrate that the proposed MobileNetV2–PCA–SVM pipeline achieves 97.58% accuracy, 96.60% precision, 96.59% recall, and 96.59% F1-score, outperforming the DenseNet201 + Bayesian-optimized SVM baseline (94.60%, 94.40%, 94.40%, and 94.40%, respectively). This improvement corresponds to a 2.98% accuracy gain, a 55% reduction in error rate, an 86% reduction in model parameters (20.31M to 2.75M), and an 85% reduction in model size (81 MB to 12 MB). These results indicate that the proposed framework provides a compact and efficient solution with strong potential for deployment in resource-constrained agricultural environments.

The test results showed that the performance of the K-NN algorithm was running optimally. There was no significant difference in the distribution of the load to the server, this made the optimization and addition of logic successful.

Background: Hand grip strength is an essential indicator of physical capacity and nutritional status that can identify obesity risk. Adipose tissue accumulation in central obesity contributes to decreased hand grip strength quality through impaired muscle force transmission. Previous studies showed inconsistent results regarding the relationship between waist circumference and hand grip strength, especially in populations with high physical activity. Objective: To analyze the relationship between waist circumference and hand grip strength in male construction workers with high physical activity in Medan City. Methods: This descriptive-analytic study with cross-sectional design involved 100 male construction workers aged 30-39 years selected using purposive sampling technique. Waist circumference was measured using measuring tape, while hand grip strength was measured using handgrip dynamometer. Data analysis used Chi-Square test with significance level α=0.05. Results: The majority of respondents had normal waist circumference (64%) with mode 70 cm and normal grip strength category (53%) with mode 41.7 kg. Chi-Square test showed significant relationship between waist circumference and hand grip strength (p=0.039). Conclusion: There is a significant relationship between waist circumference and hand grip strength in construction workers. High physical activity does not completely prevent central obesity, therefore nutritional management and health education programs are needed for optimization of body composition and muscle functional capacity.

Gununganyar Reservoir in Tuban Regency is one of the reservoirs used as a source of livelihood for the local community. However, further development and utilization of Gununganyar Reservoir have yet to be undertaken.

Non-hemorrhagic stroke occurs due to blockage of blood flow to the brain by a thrombus or embolus. The blockage results in focal neurological disorders that affect the musculoskeletal system, namely weakness in the extremities, which gives rise to nursing problems of impaired physical mobility. To overcome the problem of impaired physical mobility, rubber ball grip exercises (ball squeezing) are given. These exercises have been shown to increase muscle strength, prevent joint stiffness, and improve blood circulation. This scientific paper was conducted to determine the description of nursing care for non-hemorrhagic stroke patients with nursing problems of impaired physical mobility. During the meeting, the nurse provided rubber ball grip exercises (ball squeezing) for 10-15 minutes for 3 times in 24 hours. Evaluation of these actions showed that the patient who initially experienced weakness in the upper extremities with muscle strength 2-3 and after being given rubber ball grip exercises (ball squeezing), the problem of impaired physical mobility was resolved, as evidenced by the patient being able to perform therapy, the extremities feeling slightly lighter, and muscle strength 4. Therefore, it is recommended that non-hemorrhagic stroke patients be given rubber ball grip exercises (ball squeezing) to overcome impaired physical mobility.

This study examines the prohibition of marriage based on the babisiak oath in Nagari Lunto, Lembah Segar District, Sawahlunto City, from the perspective of Sadd al-Dzari’ah and the views of Generation Z. The babisiak oath is a traditional vow made by previous ninik mamak (customary elders) declaring that members of the Buo Bungo tribe and the Kutia Anyia Bawah tribe are forbidden to marry, as the elders had sworn a brotherhood bond known as batali budi. This research employs a qualitative field research approach. Data were collected through in-depth interviews with the Head of the Kerapatan Adat Nagari (KAN) of Lunto Village and several Generation Z members residing in the area. The collected data were analyzed using descriptive and qualitative methods. The findings indicate that, from the perspective of Sadd al-Dzari’ah, the marriage prohibition falls into the third category, namely a permissible act that has a strong potential to cause harm. Allowing such marriages could reopen historical conflicts, expose past grievances between the tribes, and potentially lead to social or physical disputes. Furthermore, Generation Z’s perspectives on the prohibition can be classified into three groups: those who remain obedient to the custom, those who hold a moderate stance, and those who tend to reject the prohibition. Despite these differences, most Generation Z respondents acknowledge that the babisiak oath has historical and social value that deserves preservation. However, they also emphasize the need to reinterpret its implementation in the contemporary context to prevent conflicts between customary law, Islamic legal principles, and individual freedom.

Mining companies are increasingly required to demonstrate environmental, social, and governance (ESG) accountability through sustainability reporting (SR). However, empirical evidence regarding the impact of SR on firm value in Indonesia’s mining sector remains inconsistent. This study aims to systematically examine the relationship between sustainability reporting and firm value using legitimacy theory as the conceptual framework. A Systematic Literature Review was conducted following the PRISMA 2020 protocol, employing narrative and thematic synthesis. Peer-reviewed articles published between 2018 and 2025 were retrieved from Google Scholar, Garuda Portal, and SINTA databases using relevant keywords. From 4,260 initial records, 11 studies met the inclusion criteria after screening, deduplication, and quality appraisal using an adapted CASP checklist. The findings reveal three dominant patterns: most studies report a positive effect of SR on firm value through improved transparency, corporate reputation, and investor confidence; several studies find no significant relationship due to short-term investor orientation; while a minority report negative effects associated with low disclosure quality and greenwashing concerns. Furthermore, the effectiveness of SR is influenced by disclosure quality, corporate governance, profitability, and leverage. This study implies that sustainability reporting can enhance firm value when disclosures are credible, consistent, and material, supporting legitimacy theory and encouraging alignment with the GRI 14: Mining Sector 2024 standard.

Loss and grief are psychological experiences that significantly affect an individual’s mental state. This process involves various emotional, cognitive, and behavioral changes that can affect a person’s well-being in the long term. This study aims to describe the emotional, cognitive, and behavioral affects that arise in individuals after experiencing loss, as well as the factors that strengthen or weaken their responses to the grieving process. The method used in this study is qualitative, with a literature review approach from various relevant clinical psychology and mental health studies. The results indicate that individuals who experience loss are vulnerable to increased emotional stress, anxiety, depression, and significant declines in social functioning. Furthermore, this article highlights that the quality of social support received, the way individuals make meaning of the loss, and the coping mechanisms they choose play a crucial role in determining the level of grief response. These factors can either accelerate or delay the healing process. An unresolved grieving process or one that is handled in an unhealthy manner can develop into more serious psychological disorders, such as Prolonged Grief Disorder (PGD). PGD is a condition characterized by difficulty in accepting the loss, which can persist for months or even years. This article emphasizes that loss is not merely an emotional disturbance but also a complex psychological process. This process requires a deep understanding, strong social support, and appropriate interventions to maintain an individual’s mental health and help them recover more effectively.

This study aims to design, implement, and compare the performance of the Backpropagation algorithm from Artificial Neural Networks and the Seasonal Autoregressive Integrated Moving Average (SARIMA) model in predicting the optimal daily rice requirement at Grillme Restaurant in Pontianak. The main problem faced by the restaurant is the uncertainty in determining the required daily rice stock, which periodically results in either understocking (shortage) or overstocking (wastage), leading to operational losses. To address this, the study utilizes historical daily rice sales data from January 2023 to April 2025 as the database for training and testing both predictive models. The SARIMA approach is employed to capture time series components (trend and seasonality), while Backpropagation is utilized to model non-linear patterns. Comparative test results indicate that the SARIMA model achieved superior accuracy compared to the Backpropagation model. This is confirmed by the Mean Absolute Percentage Error (MAPE) value of the SARIMA algorithm being 17.35%, which is lower than the MAPE value of Backpropagation at 19.62%. The MAPE values obtained by both models demonstrate good predictive capability, but it is concluded that SARIMA is more recommended for a more efficient and planned management of rice stock at Grillme Restaurant in Pontianak.

PT Adhi Karya (Persero) Tbk is a State-Owned Enterprise (BUMN) in Indonesia that operates in the construction industry. PT. Adhi Karya (Persero) Tbk. was awarded the contract for the Yogyakarta-Bawen toll road construction project, Package 1, Section 1. Construction safety is a very important aspect in the project. The toll road construction project involves work at heights, especially on erection grider work. Erection grider work is a high-risk job, so construction safety must be guaranteed. If construction safety is not guaranteed in the work environment, workers will be more careful in working to reduce risks so that work slows down. This can reduce work productivity. However, when safety is guaranteed, workers will feel safe to work so that it can increase work productivity. This study aims to determine the effect of construction safety (X) on work productivity (Y). The data collection method was carried out by distributing questionnaires to 30 respondents of erection grider workers. Data processing used the Structural Equation Modeling–Partial Least Squares (SEM PLS) method with SmartPLS 4.0 software. The results of data processing showed that construction safety had a significant influence on work productivity with a t-statistic value of 7.329 and a p-value of 0.000.
