This study aims to analyze the influence of training and development, compensation, work environment, and work motivation on employee productivity. The research employed a quantitative approach using a survey method. The population consisted of employees at manufacturing companies in Banten Province, with a sample of 120 respondents selected through purposive sampling. Data were collected using a structured questionnaire and analyzed using multiple linear regression. The results showed that training and development (t = 4.071; sig. = 0.000), compensation (t = 3.397; sig. = 0.001), work environment (t = 3.384; sig. = 0.001), and work motivation (t = 3.046; sig. = 0.003) each had a significant positive effect on employee productivity. Simultaneously, the four independent variables explained 67.4% of the variance in productivity (R² = 0.674; F = 59.821; sig. = 0.000). These findings underscore the importance of integrated HRM practices in improving employee productivity and organizational competitiveness.

The risk of accidents in the school environment is quite high, but the ability of the School Health Business Team (UKS) to handle emergencies is often still limited to theoretical knowledge without adequate practical skills. This study aims to analyze the influence of the Role Playing and Emergency Simulation (RANGGA) method on the improvement of the knowledge and skills of the UKS Team in junior high school. This study used a quasi-experiment design with a pre-post test with control group design. The research sample amounted to 60 respondents which were taken by purposive sampling technique. The intervention group was given RANGGA training, while the control group was given conventional education. The data were analyzed using the non-parametric Wilcoxon Signed Ranks Test because the data distribution was abnormal. In the intervention group, there was an increase in the average knowledge score from 88.7 to 97.9 and the skill score from 87.99 to 97.98. The results of the Wilcoxon test showed a significance value of p<0.001 for both variables in the intervention group, indicating a very strong influence of the RANGGA method. In contrast, although the control group experienced an improvement, the variation in scores remained higher and the improvement was not as significant as the intervention group. The RANGGA method is significantly effective in improving the emergency competence of the UKS Team through an experiential learning approach. It is recommended for school institutions to integrate simulation and role play methods in the UKS training curriculum to ensure optimal emergency response readiness.

Diesel engines are widely used in the transportation and industrial sectors due to their high thermal efficiency and good operational durability. However, increased fuel consumption due to inefficiency of the injection system remains a common problem. Injector characteristics, particularly nozzle diameter and injection pressure, are important factors that affect the quality of fuel atomization, air-fuel mixing, and combustion efficiency. An inappropriate combination of parameters can cause suboptimal combustion and increase fuel consumption. This study aims to analyze the effect of variations in nozzle diameter and injection pressure on fuel consumption efficiency in diesel engines. The method used is an experiment with variations in nozzle diameter of 0.150 mm, 0.152 mm, and 0.154 mm and injection pressures of 400 bar, 420 bar, and 440 bar. Tests were conducted at engine speeds of 500 rpm, 1000 rpm, and 1500 rpm with a fuel consumption measurement time of one minute for each parameter combination. Fuel consumption was measured using the volumetric method and analyzed through the fuel volumetric flow rate, fuel mass flow rate, Brake Power (BP), and Brake Specific Fuel Consumption (BSFC). The results showed that the combination of a nozzle diameter of 0.150 mm and an injection pressure of 400 bar produced the lowest BSFC value, thus providing the best fuel consumption efficiency. Meanwhile, the combination of a nozzle diameter of 0.152 mm and an injection pressure of 420 bar showed the closest condition to optimal because it was able to provide a balance between atomization quality and the amount of fuel injected, resulting in efficient and stable combustion. Thus, the efficiency of a diesel engine is influenced by the balance of nozzle size and injection pressure, not solely by the lowest fuel consumption.

Stunting is a multifactorial public health problem influenced by various risk factors that may emerge during the prenatal period. Early identification of stunting risk during pregnancy is important to support preventive interventions. This study aimed to develop a stunting risk prediction model based on maternal prenatal factors using the Random Forest algorithm. Secondary data from 172 pregnant women, consisting of 83 stunting cases and 89 non-stunting cases, were analyzed. The predictor variables included maternal age during pregnancy, height, hemoglobin level, mid-upper arm circumference (MUAC), smoking history, hypertension, asthma, and diabetes mellitus. The research stages consisted of data preprocessing, model training using Stratified 5-Fold Cross Validation, performance evaluation, external testing, and feature importance analysis. Internal evaluation results showed an accuracy of 60%, precision of 60.6%, recall of 57.3%, F1-score of 58.9%, and AUC of 0.6688. External testing yielded an accuracy of 70% and an AUC of 0.6167. Feature importance analysis identified maternal age during pregnancy as the most influential variable in the prediction process. The findings indicate that maternal prenatal factors have potential for early stunting risk identification, although the predictive performance remains moderate. This approach may serve as a foundation for developing early screening tools to support targeted interventions among high-risk pregnancies.

This study examines the effect of workload and work-life balance on employee performance through job satisfaction among working master’s students in Jakarta. This population faces dual demands from professional and academic responsibilities, making the maintenance of job satisfaction and performance increasingly challenging. Drawing on the Job Demands-Resources (JD-R) Model and Social Exchange Theory, this study investigates how job demands and resources influence employee outcomes. A quantitative causal approach was employed using data from 57 working master’s students collected through convenience sampling. Data were analyzed using Structural Equation Modeling-Partial Least Squares (SEM-PLS) with SmartPLS 4. The results show that workload negatively and significantly affects job satisfaction but has no significant direct effect on employee performance. In contrast, work-life balance positively and significantly affects both job satisfaction and employee performance. Job satisfaction positively affects employee performance and fully mediates the relationship between workload and employee performance, while partially mediating the relationship between work-life balance and employee performance. These findings support the JD-R Model and Social Exchange Theory by highlighting the role of job satisfaction as a mechanism linking work conditions and employee performance. Practically, organizations and higher education institutions should support work-life balance and manage workload effectively to enhance satisfaction and performance among working postgraduate students.

One key measure of a region's economic growth is the employment rate, as it reflects the ability of the economy to absorb labor and improve community welfare. In Jambi Province, employment opportunities are influenced by several factors, including Gross Regional Domestic Product (GRDP), population growth, and the Human Development Index (HDI). This study aims to analyze the effects of GRDP, population growth, and HDI on employment growth rates across regencies and cities in Jambi Province. The research employs a quantitative approach using panel data regression analysis covering 11 regencies and cities during the period 2017–2023. The findings indicate that GRDP growth, population growth, and HDI simultaneously influence employment levels. Partially, population growth and HDI have significant effects on employment, indicating that improvements in human development and demographic dynamics contribute to labor absorption. Meanwhile, economic growth, as measured by GRDP, has a relatively small negative effect on employment. This suggests that economic expansion does not always generate proportional employment opportunities, possibly due to structural changes and technological developments. Therefore, policies aimed at improving human capital and labor market conditions are essential to support sustainable employment growth in Jambi Province.
