Abstract

The research aims to determine the distribution and concentration levels of CO and NO2 gases based on Sentinel-5P Satellite Image processing and UHI levels based on Landsat 8 Image processing during the implementation of Covid-19 Large-Scale Social Restrictions (PSBB) in Pekanbaru City. Data processing begins by extracting CO and NO2 gas data as well as Landsat 8 imagery via cloud computing on Google Earth Engine (GEE). The PSBB policy in Pekanbaru City came into effect in 2020. The PSBB policy will limit community activities, which will affect the concentration of CO and NO2 gases as well as UHI. The research results show that before the 2019 Covid-19 PSBB the respective concentrations of CO and NO2 gases were (CO: 4.16 x 10-3 mol/m2 – 4.70 x 10-3 mol/m2) and (NO2: 4, 16 x 10-5 mol/m2 – 5.68 x 10-5 mol/m2) with a UHI temperature of 34.23 0C. Then, when the PSBB was implemented in 2020, there was a decrease in the concentration of CO and NO2 gases to (CO: 2.87 x 10-3 mol/m2 – 3.20 x 10-3 mol/m2) and (NO2: 2.98 x 10-5 mol/m2 – 5.28 x 10-5 mol/m2) with the UHI temperature decreasing to 30.24 0C. However, CO and NO2 gas concentrations increased again after PSBB in 2021 to (CO: 2.90 x 10-3 mol/m2 – 3.31 x 10-3 mol/m2) and (NO2: 2.87 x 10-5 mol/m2 – 5.76 x 10-5 mol/m2) which was followed by an increase in the UHI temperature to 32.62 0C. Therefore, it is known that the concentration of CO and NO2 gases will affect UHI. If the concentration of CO and NO2 gas increases, the UHI temperature will also increase.

Abstract

This study aims to determine the extent to which workplace bullying is related to employees' performance perception at health centers and its impact on biological stress. The research was conducted on all employees at eight health centers in Regency X, randomly selected. Workplace bullying was measured using the Negative Acts Questionnaire Revised (NAQ-R), translated into Indonesian. Performance perception was measured using the Performance Perception Questionnaire. Biological stress was assessed through cortisol levels in saliva. Among the 240 participants, the majority (60%) rarely experienced workplace bullying, with an average score of 41.00 (SD=6.532). Most participants (67.1%) had a high perception of performance, with an average score of 67.12 (SD=9.747). Pearson's test results showed a value of 0.038 with a coefficient of -0.207, indicating a significant correlation between workplace bullying and performance perception. The findings also indicate that biological stress levels, measured through cortisol, correlate with lower performance perceptions. Workplace bullying contributes 4.285% to performance perception. This study provides preliminary evidence that workplace bullying can affect employee performance through biological stress mechanisms, highlighting the importance of interventions to reduce workplace bullying to improve employee well-being and performance

Abstract

Complementary feeding (MP-ASI) is crucial for meeting the nutritional needs of infants aged 7-12 months, influencing their appetite and growth. Objective: This study evaluates the effects of MP-ASI on the appetite and growth of infants aged 7-12 months in 2024. A pre-post test design with 194 respondents assessed the impact of different types of MP-ASI on appetite and growth. All respondents received the same type of MP-ASI. Data were analyzed using univariate and bivariate analyses with SPSS. There was no statistically significant relationship between the type of MP-ASI given and weight gain. However, varieties such as spinach and eggs, and chayote and eggs, showed higher compliance with recommended nutritional standards (KPSP), indicating that MP-ASI type significantly influences adherence to these standards. Diverse MP-ASI positively affects the appetite and growth of infants aged 7-12 months. The study underscores the importance of MP-ASI variety and quality in child nutrition programs. Increasing parental education on the importance of MP-ASI variety is recommended to support optimal developmental potential in children.
