ABSTRACT
The pandemic of COVID-19 has leveraged many aspects in social life around the world. The number of infected people in Indonesia has passed 1.000.000 cases and still getting increased. The Government enforces regulations to minimize the transmission rate of the virus, namely, health protocol. One of the three pillars of health protocol is applying physical distancing and avoiding crowds. The policies have caused the community to significantly reduce activities outside due to their fear of being infected. This condition encourages the change in people’s shopping behavior, especially for daily necessities. This study aims to model shopping behavior change for daily needs or retail products before and after the pandemic. The whole research will focus on modeling the retail consumer behavior change leveraged by the pandemic using Agent-Based Simulation. In this study, the conceptual model for the observed system was mainly built as an essential input for the Agent-Based Simulation in future research. Some relevant and significant variables within the system were identified and being analyzed for constructing the conceptual model. The final results of this study are expected to present a causality analysis framework as the conceptual model that explains the causality of consumer behavior change. © IEOM Society International.
ABSTRACT
Introduction: Overweight and obesity in children is a global health problem among children of all ages. Based on the Indonesia Basic Health Research, overweight problems in children aged 5 12 years was still high, 18.8% were overweight and 8.8% were obese. In developing countries, the rate increased obesity and overweight in children 30% higher than developed countries. Aims: Our study aims to identify the relationship between gadgets use and pocket money with school children s nutritional status. Methods: This research was a cross-sectional study involving 672 schoolchildren randomly selected from ten elementary schools in Surabaya City, Indonesia. Data about duration of gadget use, pocket money, and snacking habit were assessed using structured questionnaire. Body weight and height were directly measured to calculate the subject s nutritional status using digital weight scale and stadiometer. Statistical analysis done in this study was Chi-square test to assess the relationship between variable tested. Results: The results showed that 38.8% of participants were overweight. 71.9% children were having gadget use for more than 2 hours/day, exceeding the recommended time use. Duration of gadget use and pocket money were significantly correlated with the nutritional status of school children (p 0.001). Snacking habits at home (p=0.302) and school (p=0.933) were not significantly correlated with nutritional status. Conclusions: Gadget use duration and pocket money proved to be correlated with the increase of nutritional status among schoolchildren. Thus, parents should pay more attention to control gadget use and pocket money to prevent overweight.
