Impact of large-scale social restrictions on air quality (NO₂, CO, O₃) during COVID-19: Surabaya case study, Indonesia
Asmaul Nur Fitria1, Supriyadi Supriyadi2, Muhammad Al-Irsyad3, Anindya Hapsari41. State University of Malang , ID2. State University of Malang , ID3. State University of Malang , ID4. State University of Malang , ID2025-04-23|page 27-39AbstractBackground: The COVID-19 pandemic galvanized the world at the end of 2019. It was identified as an attack on humans and spread very quickly almost all over the world. As the person in charge of protecting the community, the government makes a policy that can suppress the spread of the COVID-19 virus.
Objectives: This study aims to determine whether implementing large-scale social restrictions (PSBB) in the COVID-19 period (2020 to 2021) impacts air quality in Surabaya City, East Java.
Methods: This quantitative research uses an Analysis of Secondary Data (ADS) approach by utilizing secondary data as the primary source. This research was conducted at the Surabaya City Environmental Service, East Java Province, in July - August 2021, with the total population being all the results of NO2, O3, and CO air quality measurements in 2020-2021 during the COVID-19 pandemic in January 2020 to December 2021 at monitoring stations in Surabaya City. This study uses Wilcoxon test analysis.
Results: The results showed that implementing the first phase of large-scale social restrictions had no significant impact on NO₂ air quality in Surabaya City (p = 0.068). Implementing the transitional PSBB (second stage) had no significant impact on NO₂ air quality in Surabaya City (p = 0.068). Implementing the first and second phases of the PSBB has no significant impact on NO₂ air quality in Surabaya City (p = 0.173).
Conclusions: The implementation of PSBB Phase One and PSBB Phase Two (transition period) did not significantly impact the air quality of NO2, CO, or O3 gases in Surabaya City. This finding challenges the common assumption that lockdowns automatically improve air quality and emphasizes the need for more comprehensive environmental policies.

Correlation analysis of vaccination coverage, positivity rate, and community mobility rate on COVID-19 effective reproductive rate: SIR modeling study from Indonesia
Meirina Nur Asih Susanti1, Siti Nurrochmah2, Lucky Radita Alma3, Supriyadi Supriyadi41. State University of Malang , ID2. State University of Malang , ID3. State University of Malang , ID4. State University of Malang , ID2025-06-03|page 80-96AbstractBackground: Effective Reproduction Rate (Rt) is used to evaluate COVID-19 transmission; although Tegal City has the lowest cumulative cases in Central Java, the spread of the virus remains rapid. Intervention efforts are carried out through vaccination coverage, positivity rate, and level assessment as a shared responsibility to reduce the transmission rate.
Objectives: The purpose of this study was to estimate the spread of COVID-19 with the intervention and to determine whether there is a correlation between the COVID-19 Rt Number and vaccination coverage, positivity rate, and level assessment situation in Tegal City.
Methods: Observational quantitative research design. The type of research used was SIR (Susceptible Infected Removed) mathematical modeling and descriptive analysis through an ecological study approach and Spearman correlation statistical analysis.
Results: The results of the study showed a decrease in the number of cases of vulnerable and infected subpopulations after public health interventions, followed by the results that the positivity rate and level assessment situation were significantly correlated with the strength of the relationship powerful to the Covid-19 Effective Reproductive Rate with values (r=0.856; p=0.00) and (r=-0.712; p=0.00), while vaccination coverage was not statistically significantly correlated with a value of (r=-0.209; p=0.137).
Conclusions: The positivity rate and COVID-19 level assessment situation were statistically significantly correlated to the effective reproductive rate of COVID-19 in Tegal City with a strong correlation. Meanwhile, vaccination coverage did not correlate statistically with effective reproductive rate. Further studies must evaluate the effectiveness of combined interventions (vaccination + testing + mobility restriction) in various epidemiological settings.

The relationship between quality and quantity of antenatal care services and stunting in children 24–59 months of age
Aulia Pramesti1, Hartati Eko Wardani2, Tika Dwi Tama3, Anindya Hapsari41. State University of Malang , ID2. State University of Malang , ID3. State University of Malang , ID4. State University of Malang , ID2025-06-14|page 97-113AbstractBackground: Stunting is a chronic nutritional problem whose causes include unmet nutrition in pregnant women, lack of infant nutritional intake, and socioeconomic conditions. Dinoyo Health Center covers an area with a high stunting rate in Malang City, particularly Lowokwaru District. Previous research stated that the dominant factor causing stunting in toddlers is antenatal care (ANC).
Objectives: This study aims to determine whether stunting in toddlers in the Dinoyo Community Health Center area is caused by the quality and quantity of ANC.
Methods: The research method is observational analytic with a case-control design using a retrospective approach. The population was 1643 mothers taken from three villages: Tlogomas, Dinoyo, and Sumbersari. The research sample amounted to 69 people using purpose sampling. The research was conducted in February - March 2023. Quality measurement was based on a minimum 10T service standard, while quantity measurement was based on a minimum frequency of 4 visits using a checklist sheet instrument and MCH book with Chi-Square analysis.
Results: The results obtained for ANC quality with stunting p-value = 0.609 with OR value = 1.30 (95% CI: 0.47-3.55), while ANC quantity with stunting p-value = 0.864 with OR value = 1.09 (95% CI: 0.40-2.97).
Conclusions: It is concluded that the quality and quantity of antenatal care have no association with the incidence of stunting in children under 24-59 months in the Dinoyo Community Health Center (Puskesmas) area. These findings highlight the need for multifactor interventions beyond ANC to reduce stunting, such as improved maternal nutrition and environmental sanitation.
