Abstract

This study aims to develop, test the function, and evaluate the durability of a portable air sampling device based on an impinger system as a low-cost alternative to commercial air samplers, which are currently expensive and difficult to access for regional institutions. The device was designed using easily purchased components, including a lithium-ion battery, vacuum pump, rotameter, and an SNI-standard impinger tube. The tool was assembled in a workshop and tested for functionality, sampling stability, and battery endurance. A comparative test was conducted with a standard air sampler owned by Poltekkes Kemenkes Padang. The prototype demonstrated stable airflow at 0.5 L/min for up to 4 hours, outperforming some commercial tools in portability due to its integrated battery and solar-charging capability. Comparative sampling for SO₂, CO, and NO₂ showed no significant difference between the prototype and standard devices. The device is also significantly cheaper, costing under 7 million IDR compared to commercial units priced at 47–94 million IDR. This study concludes that the prototype is feasible for field sampling and suitable as an affordable alternative for air quality monitoring.

Abstract

Acute Respiratory Infections (ARI) remain a leading cause of morbidity and mortality among children, especially in developing countries. Poor physical housing conditions such as inadequate ventilation, low lighting, extreme temperatures, and high humidity are major risk factors for ARI. This study aimed to analyze the physical environment of homes of ARI patients in the Betungan Health Center area. A descriptive design was employed through direct observation and measurements of 95 houses.The results revealed that 50.5% of homes had inadequate ventilation, 56.9% lacked proper lighting, 54.8% had improper temperature levels, and 55.8% had high humidity. These findings indicate that most ARI-affected homes did not meet environmental health standards and may contribute to increased infection risk. Therefore, improving the physical conditions of housing is essential to reduce the incidence of ARI.

Abstract

Background: Stunting remains a major public health problem in Indonesia, with prevalence rates that exceed the World Health Organization threshold. In Bengkulu Province, particularly in the Kampung Melayu Subdistrict, stunting is exacerbated by limited access to health services, low maternal knowledge, unfavorable attitudes, and inadequate sanitation-related preventive behaviors. These factors contribute to recurrent infections and impaired nutrient absorption in children under two years old. The use of digital-based educational media is considered a promising strategy to improve health literacy and promote positive behavioral change among mothers. Purpose: To evaluate the effectiveness of the Android mobile application to assess mothers' knowledge, attitudes, and behaviors related to the prevention of stunting in children under two years old in the Kampung Melayu Subdistrict, Bengkulu City. Method: A quasi-experimental design with a control group. A total of 80 participants were selected using purposive sampling and divided into an intervention group (n = 40) and a control group (n = 40). The intervention group received health education through the SESAMA Android application, while the control group received conventional health promotion. Data were analyzed using Wilcoxon test, Paired T-test, Mann–Whitney test, ANCOVA, and MANCOVA. Results: The intervention group showed a significant improvement in knowledge, attitudes, and preventive behaviors related to stunting (p = 0.000). Mean knowledge scores increased from 5.60 to 8.23, attitude scores from 35.58 to 39.50, and behavior scores from 11.18 to 15.73. In contrast, the control group showed a significant improvement only in knowledge (p = 0.041), with no significant changes in attitudes (p = 0.172) or behaviors (p = 0.083). MANCOVA analysis confirmed that the SESAMA application had a significant effect on knowledge (p = 0.000; R² = 0.298), attitudes (p = 0.000; R² = 0.166), and behaviors (p = 0.000; R² = 0.584), with the strongest effect observed on preventive behavior. Conclusion: The SESAMA Android-based educational application is effective in improving maternal knowledge, attitudes, and behaviors related to stunting prevention and demonstrates greater effectiveness compared to conventional health promotion methods. The SESAMA model has strong potential to support digital health education strategies and may be considered for broader implementation in stunting prevention programs.
