Bullying is a recurring issue and has become a widespread concern, particularly among children and adolescents in school environments. Schools, which should ideally be safe spaces for learning, building friendships, and experiencing personal growth, often turn into places of fear and psychological distress for some students. This is largely due to the frequent violation of human rights (HR) that often goes unaddressed or is underestimated. Bullying can take many forms, including verbal, psychological, physical abuse, and increasingly, cyberbullying. Each of these forms can cause serious harm not only to the victims—who may suffer from emotional and mental trauma—but also to the perpetrators, who may experience long-term psychological consequences and develop deviant or aggressive behavior patterns. In Indonesia, bullying remains a significant issue and a major concern in the education sector. Nearly every school has faced incidents of bullying in one form or another. Cyberbullying, in particular, is harder to monitor and control since it often occurs outside the school’s jurisdiction and is carried out through social media platforms. Efforts to tackle bullying must go beyond merely protecting and supporting the victims. A comprehensive approach is necessary, one that also focuses on preventive education. Students, teachers, and parents must be consistently educated on the negative impacts of bullying, the importance of empathy, and a deeper understanding of human rights. Moreover, strict and clear sanctions must be imposed on perpetrators as a form of legal enforcement and deterrence. With a holistic strategy that involves all elements of the school and the wider community, it is hoped that educational institutions can truly become safe, inclusive, and supportive environments. Such conditions are essential for fostering not only academic growth but also the psychological well-being and character development of the nation's children.

Fatigue is a critical issue in labour-intensive small industries, especially in traditional food production such as tofu manufacturing. This study aims to develop a fatigue classification model using a decision tree algorithm by integrating subjective assessments of the work system through the Macroergonomic Organizational Questionnaire Survey (MOQS) and objective physiological indicators, specifically Cardiovascular Load (CVL). The research was conducted in a tofu home industry located in Kalisari Village, Banyumas, Indonesia. Primary data were collected from 10 workers through MOQS questionnaires and heart rate measurements taken at rest and during work. CVL values were calculated and used as labels for classification into three categories: low, moderate, and high fatigue. Meanwhile, MOQS dimension scores (organization, job, personal, environment, and technology) were transformed into interval data and used as classification features. A decision tree model was built using the CART algorithm and visualized for interpretability. The results show that all workers experienced at least moderate fatigue, with 20% categorized as high fatigue. The decision tree revealed that the dimensions of organizational and personal factors were the most influential in predicting fatigue levels. The model provides a practical and interpretable tool to support decision-making in scheduling, workload balancing, and ergonomic interventions. This study demonstrates a novel approach to combining macroergonomic assessments and physiological data with machine learning for practical fatigue risk management in small-scale food production environments.

This study aims to identify and measure the influence of customer relationships, customer satisfaction, and brand image on customer loyalty at Ryandini’s Sweet Chicken Claw business, located in Sei Sijenggi Village, Hamlet III, Perbaungan District, Serdang Bedagai Regency. A quantitative research method was employed, with data collected through observation, documentation, and questionnaires. The questionnaires used a Likert scale as a measurement tool to assess respondents’ opinions accurately. Data analysis was conducted using several stages, including validity and reliability tests, classical assumption testing, and multiple linear regression analysis, processed through SPSS version 22. These methods were used to ensure the validity of the instrument and the consistency of the findings. The research findings demonstrate that customer relationships have a significant and positive effect on customer loyalty. Customers who feel connected and valued by the business are more likely to remain loyal. Likewise, customer satisfaction—reflecting the extent to which customers' expectations are met or exceeded—has a strong and positive influence on loyalty. In addition, the brand image of the business, which encompasses customer perceptions and reputation of the product, also significantly influences loyalty in a positive direction. Furthermore, the simultaneous analysis of customer relationships, customer satisfaction, and brand image shows that all three variables jointly have a significant and positive impact on customer loyalty. This means that enhancing these three factors can strengthen customer retention and long-term commitment. These results provide valuable insights for small business owners in the food and beverage industry. Focusing on building strong relationships with customers, consistently delivering satisfaction, and maintaining a positive brand image are essential strategies to increase loyalty. For Ryandini’s Sweet Chicken Claw and similar businesses, these findings offer practical guidance for developing customer-centered marketing strategies in an increasingly competitive market.

This study aims to examine the mediating role of Organizational Citizenship Behavior (OCB) in the relationship between Perceived Organizational Support (POS), Perceived Organizational Commitment (POC), and employee performance in a state-owned enterprise in Indonesia. In the context of growing public expectations for improved service quality, organizations are challenged to enhance employee performance not only in formal roles but also in discretionary behaviors. Based on Social Exchange Theory (SET), this research proposes that POS and POC can affect performance both directly and indirectly through OCB. Data were collected through a census of 138 permanent employees at PT Jasa Raharja, East Java Branch. The analysis employed Partial Least Squares Structural Equation Modeling (PLS-SEM) to test the hypothesized relationships. The findings show that POS has a significant positive influence on both OCB and employee performance. On the other hand, POC significantly influences OCB but does not have a direct impact on performance. The results also reveal that OCB plays a partial mediating role in the relationship between POS and performance, while it acts as a full mediator in the relationship between POC and performance. These findings emphasize the importance of fostering OCB within the organization to optimize the impact of support and commitment on employee performance. Encouraging voluntary, extra-role behaviors can bridge the gap between how employees perceive organizational treatment and how they perform. The study suggests practical implications for human resource management in public sector institutions. Policies should focus on building a supportive and engaging work climate that enhances affective commitment and acknowledges employee contributions beyond formal duties. Doing so will not only improve individual performance but also contribute to broader organizational effectiveness in a competitive and service-oriented environment.

Employee shift scheduling in the hospitality industry remains a critical yet complex task due to fluctuating operational demands, fairness requirements, and labour regulations. Many hotels still rely on manual scheduling methods, which are time-consuming and prone to biases, particularly in ensuring fair workload distribution across employees. Despite numerous studies on workforce scheduling, limited attention has been given to integer linear programming (ILP) models that address gender-based restrictions and operational fairness simultaneously in real-world hotel contexts, especially in developing regions such as Central Java. This study proposes an Integer Linear Programming (ILP) model to generate optimal shift schedules for hotel staff over a 31-day planning horizon. The model incorporates operational constraints, including one shift per day, gender-based restrictions (which prevent female staff from working night shifts), availability, minimum staffing levels, and fairness in workload distribution. Key parameters and binary decision variables were defined to ensure compliance with the hotel's specific requirements. Empirical data were collected from a hotel in Central Java involving 20 employees, and the model was implemented using Python with a Gurobi solver. The ILP model successfully generated optimal schedules in under 10 seconds, significantly outperforming the manual method, which required over 4 hours. While the manual schedule resulted in an imbalance where some employees worked over 27 days and others only 22, the ILP approach enforced a strict maximum of 26 working days for all staff. Furthermore, the fairness index (FI) improved from 19.2% in the manual method to 0% in the ILP-generated schedule, indicating complete equity in workload allocation. The proposed ILP model demonstrates its effectiveness in improving scheduling fairness, operational efficiency, and compliance with labour policies. This work not only addresses a critical research gap in hospitality scheduling practices in Indonesia but also offers a replicable framework for other labour-intensive service sectors. Future research may explore multi-objective extensions incorporating employee preferences, satisfaction, and dynamic demand fluctuations.

The purpose of this paper is to examine the role of Green Intellectual Capital (GIC) in the development of waste-to-energy (WtE) technologies, which is of special relevance for the incineration plants in the Gulf Cooperation Council (GCC) countries. Although previous studies have focused primarily on technological and infrastructural aspects, this paper investigates the contribution of intangible assets such as green human, structural, and relational capital towards the performance and sustainability of WtE systems. Adopting a mixed-method approach, the results show that Green Structural Capital has the first place in supporting operational efficiency, followed by Green Human Capital and Green Relational Capital. The statistical analysis based on Structural Equation Modeling (SEM) shows that all GIC dimensions are positively related to plant performance, with institutionalized knowledge and systems as the most significant enablers of innovation. Qualitative findings also highlight constraints such as lack of training, unhandy knowledge systems, and poor public-private interaction. The findings recommend policy suggestions for promoting GIC assimilation within environmental infrastructure and provide a region-based theoretical model connecting knowledge-based resources and sustainable waste management practices. The study emphasizes the importance of integrating intellectual capital into the strategic decision-making process of waste-to-energy plants to enhance their operational effectiveness and long-term sustainability. Additionally, the research underlines that fostering a knowledge-sharing culture and enhancing collaboration between various stakeholders, including governmental bodies, private firms, and research institutions, is critical for the success of green initiatives. Training programs aimed at developing green human capital and improving public-private partnerships are essential to overcoming the current barriers to innovation in the WtE sector. This study has practical and scholarly implications in unifying the focus from just technology to the facilitating role of human and intellectual capital in green transformation, further bridging the gap between environmental sustainability and technological advancements in waste management.

This study was conducted at Bio Live Healthy Home, located in Sei Bamban District, Serdang Bedagai Regency.

This study aims to identify the factors that influence the local community in developing the swallow nest business and to examine how the practice of swallow nest farming aligns with the principles of Islamic business ethics in Marioriwawo District, Soppeng Regency. The swallow nest industry has grown significantly in this area, shifting the economic landscape from primarily agricultural activities to a more diversified business sector. Before the emergence of this business, most residents were involved in farming. However, due to factors such as unpredictable harvests and unstable agricultural income, many community members have turned to swallow nest cultivation as an alternative and promising source of livelihood. According to Islamic business ethics, the practice of breeding swallows is permissible, as long as it does not involve cruelty to animals. This view is supported by the Indonesian Ulema Council (MUI) Fatwa Number 2 of 2012, which states that raising or cultivating swallows is allowed, provided the birds are not harmed or subjected to distress. Furthermore, the consumption and trade of swallow nests are also considered halal under Islamic law, adding to the business's appeal among the Muslim population. To explore the underlying motivations and social dynamics of this business shift, the study employed a qualitative research method. This approach was chosen to gain a deeper understanding of the local context, including the experiences, beliefs, and socioeconomic conditions of the people involved. The results revealed several influencing factors: the potential for high profit from selling swallow nests, the challenges faced in traditional agriculture (such as frequent crop failure), and the religious assurance that the business is acceptable under Islamic teachings. Overall, the swallow nest business represents a strategic and ethical economic opportunity for the community, enabling them to improve their livelihoods while staying aligned with their religious values.

The high bounce rate of the SOCO by Sociolla app, reaching 57.8%, and the decline in user engagement indicate a serious challenge in maintaining consumer loyalty amidst highly dynamic digital platform competition. In an era when consumers have many alternatives and high expectations for digital experiences, building meaningful relationships through brand experience is crucial. Brand experience encompasses not only functional interactions but also emotional and sensory dimensions that shape consumer perceptions of service value and quality. This study aims to analyze the influence of brand experience on brand loyalty by including perceived quality and brand trust as mediating variables. A quantitative approach was used through the Structural Equation Modeling (SEM) method on 430 active SOCO app users. The results showed that brand experience significantly influences brand loyalty directly (t=2.195, p=0.014) and also indirectly through perceived quality (t=2.457, p=0.007) and brand trust (t=5.563, p=0.000). Overall, this model explains 62.7% of the variance in brand loyalty. These findings underscore the importance of experiential marketing strategies in increasing customer satisfaction, building trust, and maintaining long-term loyalty. A strong brand experience can create deep emotional connections, strengthen perceptions of service quality, and foster brand trust, particularly in the digital beauty sector, which relies heavily on image and user convenience. Theoretically, this study contributes to the development of brand loyalty models in the digital environment. Practically, the results of this study provide guidance for digital beauty app managers like SOCO to design more immersive, personalized, and consistent user experience strategies to increase customer retention and strengthen their competitive position.

Type 2 diabetes mellitus is a long-term or chronic disease that needs to be managed properly. One of the biggest challenges for people with type 2 diabetes mellitus is their ability to control their weight. This cross-sectional study aims to determine the ability to control their weight in people with type 2 diabetes mellitus and the factors that influence it. Respondents in this study were 96 respondents using a purposive sampling technique. The independent variables were factors related to the ability to control their weight, while the dependent variable was the ability to control their weight. Data collection used a questionnaire, and statistical testing was carried out using Spearman's rho with a significance level of 0.05. The results of the study showed that most respondents (71.9%) used oral diabetes medication, almost all respondents (37.5%) used insulin diabetes medication, most respondents (59.4%) had suffered from diabetes for 1-2 years, most respondents (52%) were committed to maintaining their weight in the sufficient category, and most respondents (62.5%) had the ability to control their weight in the fairly good category. The Spearman rho statistical test results showed a relationship between the duration of diabetes (p-value: 0.027) and commitment (p-value: 0.039) with the ability to control weight, while there was no relationship with other factors. The relatively good ability to control weight in patients newly diagnosed with type 2 diabetes mellitus may be due to the patient's awareness and motivation that creates a commitment to control their health condition to prevent worsening conditions. It is hoped that patients with type 2 diabetes mellitus can maintain the ability to control their weight so that glucose levels remain under control.
