This study aims to analyze the influence of career development and job training on employee performance, with work motivation as an intervening variable, at the Pakan Rabaa Community Health Center in Lima Puluh Kota Regency. The background of this study is based on the importance of improving the quality of human resources through career development strategies and targeted job training programs, as well as the role of work motivation as a driving factor for employee performance. The research method used is Structural Equation Modeling (SEM) with the Partial Least Square (PLS) approach. Data were collected through distributing questionnaires to 66 respondents who are employees of the Pakan Rabaa Community Health Center. The results of the study show several important findings. First, career development has a positive and significant effect on work motivation. Second, job training has a positive but insignificant effect on work motivation. Third, career development has a positive but insignificant effect on employee performance. Fourth, job training has a positive and significant effect on employee performance. Fifth, work motivation has a positive but insignificant effect on employee performance. Sixth, career development has a positive but insignificant effect on employee performance through work motivation as an intervening variable. Seventh, job training also had a positive but insignificant effect on employee performance through work motivation as an intervening variable. This finding indicates that although career development and job training have a positive relationship with performance, the effect is not always significant when mediated by work motivation. Other factors beyond work motivation may also influence employee performance at the Pakan Rabaa Community Health Center. This study recommends that management strengthen career development and job training programs relevant to employee needs, while identifying other motivational factors that can further enhance performance.

The rapid growth of Micro and Small Enterprises (MSEs) in the culinary sector in Denpasar City has made a significant contribution to the regional economy and job creation. This sector has become one of the key drivers of local economic activity, attracting both residents and tourists. However, despite its potential, challenges persist. Fluctuations in the number of MSE actors and the suboptimal use of social media for marketing hinder sustainable income growth. Moreover, poor decisions regarding business location and inappropriate pricing strategies often become barriers to achieving business success. This study aims to analyze the simultaneous effects of business location, pricing, and social media usage on the income of culinary MSEs in Denpasar City. A quantitative approach was employed using a survey method, in which questionnaires were distributed to 99 culinary MSE actors. The collected data were analyzed using multiple linear regression to evaluate the influence of each variable both simultaneously and partially. The results reveal that business location, pricing, and social media usage together have a significant effect on MSE income. Partially, business location and pricing show a positive and significant influence, indicating that strategic location selection and competitive pricing play crucial roles in increasing income. In contrast, social media usage does not significantly affect income, suggesting that while digital platforms have potential as marketing tools, their benefits remain limited without effective content strategies and adequate digital literacy. These findings highlight the importance of strengthening fundamental business aspects, particularly location and pricing strategies, to improve MSE performance. Furthermore, policy support and targeted assistance programs focusing on enhancing digital literacy and managerial capacity among MSE actors are essential. By addressing these areas, the culinary sector in Denpasar City can achieve more sustainable growth and contribute even more effectively to the local economy.

This study aims to examine the influence of self-efficacy and learning environment on learning outcomes, with learning motivation as a mediating variable, among students of SMK Negeri 44 Jakarta. Employing a quantitative approach with a survey method, the research involved a population of 175 students, all of whom were included as the sample through a total sampling technique. Data analysis was conducted using Structural Equation Modeling–Partial Least Squares (SEM-PLS) with SmartPLS 4.0 software. The analytical procedures encompassed measurement model analysis, structural model analysis, and hypothesis testing for both direct and indirect effects.The findings reveal a positive and significant direct effect of self-efficacy on learning outcomes, indicating that students with higher confidence in their abilities tend to achieve better academic performance. Similarly, the learning environment was found to have a positive and significant direct effect on learning outcomes, suggesting that supportive academic surroundings contribute meaningfully to student achievement. However, the study found no significant direct effect of learning motivation on learning outcomes, nor any significant mediating role of learning motivation in the relationships between self-efficacy and learning outcomes or between learning environment and learning outcomes. These results imply that while self-efficacy and a conducive learning environment are key determinants of academic success, the role of learning motivation as an intervening variable may not be as substantial in this context. The absence of mediation suggests that motivation alone may not bridge the gap between personal and environmental factors and actual academic performance. This study contributes to educational research by providing empirical evidence on the complex interplay between psychological, environmental, and motivational factors influencing student achievement, highlighting the need for educators to strengthen both self-belief and learning conditions to optimize outcomes.

The Maternal Mortality Rate (MMR) and Infant Mortality Rate (IMR) are critical indicators in assessing the quality of public health services. In 2024, both MMR and IMR in Lamongan Regency remained relatively high, indicating the need for strengthened health interventions. Health workers, especially midwives, play a vital role in improving maternal and child health. One of the government’s strategies to reduce maternal and infant mortality is expanding midwife service coverage at primary health facilities and ensuring the presence of village midwives as the frontline providers across the region. Village midwives are expected to meet established service standards to ensure the quality of maternal and child health care. Service effectiveness and efficiency are commonly measured through indicators such as first antenatal visit coverage (K1), fourth antenatal visit coverage (K4), postpartum visit coverage (KF3), and delivery assistance by health workers. However, in Lamongan Regency, the performance of village midwives has not been optimal, with several indicators falling short of set performance targets.This study aimed to analyze the relationship between the quality of work life and the performance of village midwives in Lamongan Regency in 2025. The research used a quantitative method with a cross-sectional study design. The study population comprised all village midwives in Lamongan Regency, with a sample of 80 respondents selected randomly. The independent variable in this study was the quality of work life, while the dependent variable was village midwife performance. Data were collected through questionnaires and analyzed using the chi-square statistical test. The results showed no significant relationship between the quality of work life and the performance of village midwives in Lamongan Regency in 2025. These findings suggest that other factors beyond work life quality may influence midwives’ performance.

Dependence on fossil fuels, such as gasoline and diesel, has become a global issue that affects environmental sustainability and energy security. Increasing greenhouse gas emissions, decreasing natural resource reserves, and instability of global energy prices encourage the need for innovation in motor vehicle fuel systems. This study aims to assess fuel efficiency and engine performance on a 110 CC motorcycle with a standard compression of 10.7:1, by utilizing a mixture of RON 90 gasoline and alcohol. The main focus of the study is to compare the effect of varying alcohol content on engine power output, with mixtures of E12.5, E17.5, and E22.5. The method used is an experimental method with three variables, namely the independent variable (type and content of fuel mixture), the dependent variable (engine power), and the control variables (engine condition, temperature, and testing method). Testing was carried out using a combination of iridium spark plugs and standard spark plugs, as well as variations in Pilot Jet sizes 34 and 35 on aftermarket carburetors. Each combination was tested to determine its effect on the maximum engine power. The results showed that a blend of E12.5 fuel with Pilot Jet 35 and iridium spark plugs produced the highest power output compared to other tested combinations. This combination was proven to optimize combustion in the combustion chamber, thereby improving engine efficiency and performance. Conversely, increasing the alcohol content above E12.5 did not provide a significant increase and even tended to decrease power due to alcohol's lower calorific value than gasoline. The conclusion of this study is that the use of an aftermarket carburetor with Pilot Jet 35 and iridium spark plugs, combined with an E12.5 fuel blend, can be an effective alternative for improving the performance of a 110cc motorcycle. These findings are expected to serve as a reference for the development of more efficient and environmentally friendly blended fuel technology.

The development of electric motor vehicles drives the need for efficient, stable, and reliable energy storage systems.

This research is motivated by the low utilization of accounting information by Micro, Small, and Medium Enterprises (MSMEs), which can impact suboptimal business decision-making. Accounting information plays an important role in helping business actors manage operational activities, plan finances, and evaluate business performance. Therefore, this study aims to analyze the influence of accounting knowledge, business scale, and business experience on the perception of the use of accounting information, both partially and simultaneously. The approach used in this study is a quantitative approach with a causal research type. The population in this study were all MSMEs in Ngronggot District, Nganjuk Regency, totaling 162 business units. The sample used was 62 respondents, obtained through a simple random sampling technique with calculations using the Slovin formula. The data collection method was carried out by distributing questionnaires to predetermined respondents. Data analysis used multiple linear regression methods with the help of SPSS software version 27. The results of the study indicate that partially, accounting knowledge and business scale have a significant influence on the perception of the use of accounting information. This indicates that the greater the level of accounting knowledge and the larger the business scale, the higher the positive perception of the importance of using accounting information. Conversely, business experience did not show a significant partial effect, indicating that the length of time a person has been running a business does not always lead to increased use of accounting information. However, simultaneously, all three variables—accounting knowledge, business scale, and business experience—significantly influenced perceptions of the use of accounting information. This finding implies that increasing accounting knowledge and expanding business scale need to be addressed in MSME empowerment programs to optimally utilize accounting information.

This study aims to analyze various factors that influence employee performance at Coffee Coftea Kendari. Specifically, this study examines (1) the influence of the work environment on employee performance, (2) the influence of work discipline on employee performance, (3) the influence of the work environment on employee performance, (4) the influence of work discipline on employee performance, (5) the influence of work motivation on employee performance, (6) the influence of the work environment on employee performance through work motivation, and (7) the influence of work discipline on employee performance. The results of the study indicate that the work environment has a positive and significant effect on employee performance at Coffee Coftea Kendari. This means that the better the work environment provided, the higher the employee performance. However, the work environment does not have a significant effect on work motivation. This shows that although a comfortable work environment can improve performance, work motivation factors are more influenced by other variables, such as work discipline. Work discipline has been shown to have a positive and significant effect on work motivation and employee performance. This shows that employees who have high work discipline tend to have a stronger motivation to work well, which in turn improves their performance. Work motivation was also found to have a positive and significant influence on employee performance, confirming that high motivation can encourage employees to improve their productivity and work quality. Furthermore, this study also found that work motivation only significantly mediated the effect of work discipline on employee performance, but did not mediate the effect of the work environment on employee performance. This means that although work motivation plays an important role in improving performance influenced by work discipline, motivation does not act as a mediator linking the work environment to employee performance.

This study was conducted at Family Pharmacy in Pekanbaru City with the objective of examining the relationship between emotional intelligence and work stress, as well as their combined effect on employee performance. The research population consisted of all 150 employees in the production department. Using the Slovin formula, a sample of 60 respondents was selected through accidental sampling. Data collection was carried out via an online questionnaire distributed through Google Forms. The analytical methods employed were correlation analysis to assess the relationship between variables and multiple linear regression to measure their simultaneous influence on performance. The results indicated a negative relationship between emotional intelligence and work stress, meaning that employees with higher emotional intelligence tended to experience lower levels of work stress. Furthermore, when examined together, emotional intelligence and work stress had a significant impact on employee performance. Specifically, these two variables contributed 47.4% to the variance in performance, while the remaining 52.6% was influenced by other factors not addressed in this study. The findings highlight the importance of emotional intelligence as a critical factor in managing workplace stress and enhancing performance, especially in the pharmaceutical industry where precision, cooperation, and adaptability are essential. Improving employees’ emotional intelligence may serve as a strategic approach to reducing work-related stress and fostering better performance outcomes. Organizations are therefore encouraged to invest in training and development programs that emphasize emotional regulation, empathy, interpersonal skills, and effective communication. Future research should consider incorporating additional variables such as work motivation, organizational culture, leadership style, and job satisfaction to gain a more comprehensive understanding of the determinants of employee performance. Expanding the research scope to different departments and industries could also provide broader insights into how emotional intelligence and work stress interact across diverse work settings.

This article explains the influence of intellectual performance efficiency (MVAIC) and the moderating effect of innovation capital on company performance. The research population includes manufacturing companies listed on the Indonesia Stock Exchange (IDX) from 2019 to 2024. This study used a purposive sampling method, and 18 companies meet the criteria, resulting in 108 observations. The MVAIC method was chosen because it encompasses RCE and INCE, and research on this topic in Indonesia is limited. Panel data regression was used for estimation, and Sequential Residual Centering (SRC) was applied to address multicollinearity. The study findings indicate that CEE, HCE, and SCE enhance profitability, while MVAIC, CEE, SCE, and RCE improve productivity. An important finding in this study is the moderating effect of INCE. INCE provides the appropriate environment and mechanisms to enable HC to effectively generate new ideas and improve ROA. Excessive investment in INCE can disrupt the optimization of the company's internal systems, processes, and infrastructure (SC), thereby affecting profitability. Excessive innovation priorities can divert resources from developing and maintaining strong external relationships (RC), thereby hindering productivity. The results of this study contribute to the understanding of potential trade-offs in IC investment, showing that excessive INCE can hinder financial performance derived from SC and RC. The implication, companies need to balance the allocation of IC resources to achieve holistic performance, rather than focusing solely on innovation.

This study aims to investigate the effects of liquidity, financial leverage, capital structure, and operating cash flow on financial performance, with financial distress serving as a mediating variable. The population comprises transportation and logistics companies listed on the Indonesia Stock Exchange (IDX) from 2019 to 2023, totaling 37 companies. The sample includes 20 companies, with quarterly financial reports yielding 400 observations. Secondary data were employed, and purposive sampling was utilized for sample selection. The analysis was conducted using panel data analysis at a 5% significance level, facilitated by STATA Version 17 software. Mediation was tested utilizing the Sobel test with a critical value of 1.96. The results reveal that liquidity significantly impacts both financial distress and financial performance; financial leverage significantly affects both financial distress and financial performance; capital structure significantly influences financial distress but does not significantly affect financial performance; operating cash flow does not significantly impact financial distress but significantly affects financial performance. Collectively, liquidity, financial leverage, capital structure, and operating cash flow significantly influence financial distress. Furthermore, liquidity, financial leverage, capital structure, operating cash flow, and financial distress together have a significant effect on financial performance. Mediation analysis indicates that financial distress significantly mediates the relationships between liquidity, financial leverage, capital structure, and financial performance, whereas financial distress does not significantly mediate the effect of operating cash flow on financial performance. It is recommended that transportation and logistics companies listed on the IDX actively enhance liquidity, optimally manage leverage and capital structure, and strengthen operational cash flow management to minimize financial distress risk and sustain financial performance.

Motorcycle engine performance is highly dependent on the air intake system, which plays a crucial role in the combustion process. One common method for improving engine performance is modifying the intake system, either by installing additional devices or adjusting the quantity of incoming air. One innovation that is starting to be widely used is the Jet Ranger, an additional device on the intake duct that is claimed to be able to increase air flow into the combustion chamber. This study aims to determine the effect of the use of Jet Ranger and variations in the quantity of incoming air on the maximum power of a 150 cc motorcycle engine, as well as to analyze the interaction between the two variables. The study was conducted using an experimental method with a two-way factorial approach. The independent variables in this study consisted of two factors, namely the use of Jet Ranger (without Jet Ranger and with Jet Ranger) and variations in the quantity of incoming air divided into four levels (0.008; 0.012; 0.016; and 0.020 kg/s). Maximum power testing was conducted using a Leads dynotest, while the mass of incoming air was calculated based on air velocity measured using a digital anemometer. The test data were statistically analyzed using a two-way ANOVA to identify the effect of each factor and the interaction between them on engine power. The results of the study indicate that the use of Jet Ranger significantly increases engine power. Variations in the quantity of intake air also significantly affect the power generated. In addition, the interaction between the use of Jet Ranger and the quantity of intake air is proven to have a significant impact on increasing the maximum engine power. These results are in line with the theory of intake systems which states that increasing optimal air flow can increase the volumetric efficiency of the engine, and are supported by findings from previous studies. Therefore, these findings can be used as a reference in the development of air intake systems on motorcycles to achieve more optimal engine performance.
