This study aims to analyze the effect of wages, workload, and work discipline on employee performance at Bakpia Latief MSME in Kediri. The research method employed is quantitative with a survey technique. The sample consists of 32 respondents selected through a saturated sampling technique. Primary data were collected using a Likert-scale questionnaire that had been tested for validity and reliability, while secondary data were obtained from documentation and literature review. Data analysis was conducted using multiple linear regression preceded by classical assumption tests. The results indicate that wages have a positive and significant effect on employee performance, while workload and work discipline do not have significant partial effects. However, simultaneously, the three independent variables significantly influence employee performance, with a coefficient of determination (R²) of 0.579, indicating that 57.9% of employee performance variation can be explained by wages, workload, and work discipline. This study highlights the importance of a fair wage policy in enhancing performance, although other factors such as workload and discipline still need to be managed proportionally.

This study aims to analyze the influence of work-family conflict, job stress, and compensation on employee performance at PT Nusa Gas Pratiwi. A quantitative approach with a survey method was employed, and data were collected through questionnaires distributed to 35 permanent employees. The data were analyzed using multiple linear regression with SPSS software. The results indicate that work-family conflict, job stress, and compensation have a positive and significant effect on employee performance both partially and simultaneously. The coefficient of determination (R²) of 0.900 implies that these three variables explain 90% of employee performance variation, while 10% is influenced by other factors outside the model. These findings reinforce the Job Demand-Resource and Role Enrichment theories, suggesting that job stress and role conflict can become positive driving forces when balanced with fair compensation and organizational support. Therefore, maintaining equilibrium between psychological and economic factors is essential to enhance employee productivity and loyalty.

This study aims to examine the effect of Environmental, Social, and Governance (ESG) disclosure and energy price volatility on stock returns of energy sector companies listed on the Indonesia Stock Exchange (IDX) during the 2022–2024 period. A quantitative approach was employed using multiple linear regression as the analytical method. The sample consisted of 10 energy companies selected through purposive sampling, based on the availability of sustainability reports, stock price data, and research completeness. The results indicate that ESG disclosure has a positive and significant effect on stock returns, suggesting that companies with higher sustainability transparency tend to gain stronger investor confidence. Energy price volatility also shows a positive and significant effect on stock returns, reflecting the sector’s sensitivity to global energy price dynamics. Simultaneously, both variables significantly influence stock returns, although the relatively low coefficient of determination implies that other factors should also be considered. This study highlights the importance of integrating internal factors (ESG) and external factors (energy price volatility) for investors when making investment decisions in the energy sector.

The purpose of this study was to explore differences in students creative thinking abilities based on gender and domicile. The research method used was descriptive quantitative. Sampling used proportional random sampling technique at Public Junior High Schools in South Konawe Regency. The research instrument used a creative thinking test as primary data. The data analysis technique used the winsteps program with scalogram analysis. The results showed that female students tended to be superior in fluency, originality, and elaboration, both at very high and low levels of creative thinking ability, while male students showed superiority in flexibility. This difference can be influenced by biological, psychological, and social factors that play a role in cognitive development and creativity. In addition, differences in creative thinking abilities were also found based on domicile. Urban students are superior in several indicators at very high levels of creative thinking ability, but are more susceptible to decreased creativity at very low levels compared to rural students. Environmental factors such as access to educational resources, intellectual stimulation, and higher social support in urban areas play a role in this difference. Overall, these findings confirm that gender and domicile significantly influence students creative thinking abilities.

This study examines the application of Educational Data Mining (EDM) to predict the academic per-formance of first-year students at the Catholic University of Bukavu and the Higher Institute of Edu-cation (ISP) in the Democratic Republic of Congo. The primary objective is to develop a model that can identify at-risk students early, providing the university with a tool to enhance student support and academic guidance. To address the challenges posed by data imbalance (where successful cases outnumber failures), the study adopts a hybrid methodological approach. First, the SMOTE algorithm was applied to balance the dataset. Then, a stacking classification model was developed to combine the predictive power of multiple algorithms. The variables used for prediction include the National Exam score (PEx), the secondary school track (Humanities), and the type of prior institution (public, private, or religious-affiliated schools), as well as age and sex. The results demonstrate that this approach is highly effective. The model is not only capable of predicting success or failure but also of forecasting students' performance levels (e.g., honors or distinctions). Moreover, the use of the Apriori association rule mining algorithm allowed the identification of faculty-specific success profiles, transforming prediction into an interpretable decision-support tool. This research makes several significant contributions. Practically, it provides the University of Bukavu with a tool for student orientation and early risk detection. Methodologically, it illustrates the effectiveness of a combined approach to EDM in an African context. However, the study acknowledges certain limitations, including the non-public nature of the data and the geographical specificity of the sample. It therefore proposes avenues for future research, such as the integration of Explainable AI (XAI) techniques for more refined and transparent analysis of the results.

Livestock production in rural communities relies heavily on the availability and quality of animal feed. In Aek Korsik Village, Asahan Regency, farmers continue to use manual methods to chop forage, which are time-consuming, inconsistent, and physically demanding. To address these issues, a portable forage chopper machine was designed and introduced through a community service program (KKN). The machine features a compact mechanical system powered by a small motor, making it lightweight, mobile, and easy to operate in various conditions. The implementation process included three stages: machine development, field testing, and community training. During testing, the machine efficiently processed forage materials like grass, corn stalks, and agricultural residues, producing uniform feed sizes much faster than manual methods. Farmers reported reduced workload, improved availability of chopped forage, and better livestock feeding practices. The portable design allowed the equipment to be shared among farming groups, fostering cooperation. This study underscores the role of appropriate technology in addressing rural agricultural challenges. By integrating engineering innovation with community service, the portable forage chopper machine enhances technical efficiency and socio-economic empowerment for farmers. Future improvements should focus on durability, cutting capacity, and sustainable energy alternatives to better meet the needs of smallholder farmers.

Criminal liability in modern law is built on the assumption that every individual is a rational and autonomous moral agent. However, neuroscientific evidence suggests that structural disruption of the amygdala and prefrontal cortex significantly impairs the capacity to judge actions ethically. This study aims to analyze the influence of neurological disorders on an individual's moral capacity and to formulate legal parameters for assessing criminal liability based on actual capacity. The research method employed normative legal research with a conceptual approach. The results indicate that perpetrators with dysfunction in the amygdala-PFC circuit experience a degradation of moral capacity that weakens the basis for the formation of mens rea in a substantive sense and falls outside the reach of legal systems that still rely on a model of responsibility based on the assumption of universal free will. The criminal legal system, in its current form, lacks a precise evaluative mechanism to distinguish between perpetrators with impaired moral control and those acting deliberatively. In this situation, the construction of criminal liability cannot be standardized, and reformulation of evaluation instruments is necessary to avoid sentencing bias against individuals with structural impairments in ethical capacity.

This research aims to analyze the governance forms implemented by the village government in the breakfast culinary tourism program to empower Micro, Small, and Medium Enterprises (MSMEs) in Punden Rejo Village, Tanjung Morawa District, Deli Serdang Regency. It explores the application of good governance principles in local economic development based on culinary tourism. Using a descriptive qualitative approach, the study collected data through in-depth interviews, observations, and documentation from village officials, MSME actors, and tourists. The study is guided by Sedarmayanti's principles of good governance, particularly participation and accountability, linked to MSME empowerment. The results reveal that the breakfast culinary tourism management has not been optimal. Accountability is weak, as the village government has not registered or mentored MSMEs in the tourism sector to obtain a Business Identification Number (NIB) from the local Cooperative and MSME Office. Additionally, there is a lack of reporting on tax deductions and minimal support for business capital and training, causing many MSMEs to cease operations. From a participatory perspective, the village government has not actively involved community institutions like Pokdarwis, PKK, and Karang Taruna in planning and implementing activities, resulting in weak social support for MSMEs. Overall, the management of breakfast culinary tourism in Punden Rejo Village has not optimally empowered MSMEs due to weak implementation of accountability and participation principles. The success of sustainable tourism depends on cooperation between the village government, MSMEs, and local institutions to build a participatory and accountable tourism management system.

Coffee is one of the most widely consumed beverages worldwide, including in Indonesia. Coffee consumption has become part of people's daily habits, whether as a companion for work, relaxation, or as part of social culture. However, this habit is often associated with the potential for increased blood pressure due to caffeine, which is a stimulant to the central nervous system and can affect the function of the heart and blood vessels. This study aims to analyze the relationship between the frequency of coffee consumption and systolic and diastolic blood pressure in adults. The research method used a quantitative approach with a correlational design. The study sample consisted of 100 adult respondents selected through a purposive sampling technique based on certain criteria, such as not currently taking antihypertensive medication and having no history of serious cardiovascular disease. Data collection was carried out in two stages. First, respondents completed a questionnaire containing information on the frequency and habits of coffee consumption, including the number of cups per day and the type of coffee consumed. Second, blood pressure was measured using a digital sphygmomanometer to obtain accurate systolic and diastolic blood pressure data. The results of the statistical analysis showed a significant positive correlation between the frequency of coffee consumption and increases in blood pressure, both systolic and diastolic. Specifically, respondents who consumed more than two cups of coffee per day tended to have higher blood pressure values compared to those who consumed one cup or less. This finding has important implications for health promotion efforts, particularly in educating the public about wise coffee consumption. Recommendations include limiting coffee intake, choosing coffee with low caffeine content, and balancing this with a healthy diet, regular physical activity, and stress management as part of a healthy lifestyle.
