Abstract

This study aims to validate the correlation between meteorological factors and air pollution with the spread of Covid-19 in Jakarta, Indonesia. This study examined the Covid-19 cases of Jakarta and its five municipalities. The secondary data of Covid-19 cases, includes Daily Positive Cases (DPC) and Total Daily Positive Cases (TDPC), were retrieved from the Health Office of DKI Jakarta Province, while the meteorological and air pollution parameters were obtained from the online database archives. Kendall and Spearman rank correlation tests were used to analyze correlation between DPC and TDPC with meteorological and air pollution parameters. This study found that Air Quality Index and PM10 showed a significant positive correlation with DPC in municipalities of Jakarta. Also, the average air temperature was positively correlated to TDPC in all region of Jakarta. Average air temperature, Air Quality Index, and PM10 were the factors that take into account for the spread of Covid-19 pandemic in Jakarta, Indonesia. The warmer temperature associated to the higher number of case. Thus, there are no indications that the spread of Covid-19 in subtropical or temperate country may decrease when entering a warmer season that resembles the climatic characteristics in tropical region. Additionally, the significance of air pollutant factors implies that reducing air pollution should be promoted as it might reduce the spread of Covid-19. The findings of this study would be useful to support the strategy and policy in preventing the spread of Covid-19 in the country.

Abstract

Itinerant tailors in urban Indonesia often work in prolonged static postures within mobile workstations lacking ergonomic support. This study examines the prevalence of musculoskeletal complaints and postural risks among 30 male itinerant tailors in Lenteng Agung, South Jakarta. Using a mixed-method approach, quantitative data were collected through the Nordic Body Map (NBM) and Rapid Entire Body Assessment (REBA), while qualitative insights were obtained via semi-structured interviews. Results showed that 100% of participants fell into high or very high ergonomic risk categories, with prevalent discomfort in the buttocks, lower back, and hips. No statistically significant correlation was found between age or work duration and complaint severity, indicating that workstation design plays a more critical role. Interview findings revealed self-adapted seating modifications and a strong demand for portable ergonomic improvements. The study highlights the urgent need for anthropometrically informed seating solutions compatible with mobile informal labor settings. These findings inform context-sensitive design strategies that prioritize adjustability, user comfort, and occupational health in underserved worker populations.
