RESUMO
Introduction: Postpartum family planning (PPFP) has been reported to decrease the risk of stunting by increasing the interval between pregnancies by 0.9 percent every month. In Indonesia, the prevalence of stunting affects 21.6% in 2022; however, it is expected that by 2024, the figure would drop to 14%. Objective: This study aims to analyze the relationship between gender equality and husband support in the use of PPFP. Methods: The study was conducted using a cross-sectional method and took place from August to October 2022. The participants comprised 210 women who had given birth in the first 4 to 12 months in Kulon Progo, Yogyakarta, Indonesia. The data was collected from women who visited the pediatrics and family planning clinics of community health centers from August to October 2022, using a structured questionnaire and analyzed using both the Chi-Square Test and Binary Logistic Regression Analysis. Results: The results showed that 38.1% of the participants used PPFP. The estimated results reveal that variables such as education, husband support, gender equality, home visits, and postnatal visits (p < 0.05) influenced the implementation of postpartum contraception. While other variables such as age, occupation, income, number of children, and parity did not affect the model (p > 0.05). Conclusion: Participating in postpartum family planning requires the husband's support and gender equality. We recommend a deliberate effort on improving postnatal mothers using postpartum family planning, one of the strategies is to increase intensive outreach to pregnant women with higher education to their husbands about the importance of postpartum family planning.
RESUMO
Biosynthesis of metal nanoparticles is an area of interest among researchers because of its eco-friendly approach. Current study focuses at biosynthesis of silver nanoparticles (AgNPs) and optimization of physico-chemical conditions to obtain mono-dispersed and stable AgNPs having antimicrobial activity. Initially Bacillus mojavensis BTCB15 produced silver nanoparticles (AgNPs) of 105 nm. Silver nanoparticles (AgNPs) were characterized by particle size analyzer, UV-Vis Spectroscopy, Fourier transforms infrared spectroscopy (FTIR), Atomic force microscopy (AFM), and X-ray diffraction (XRD). Whereas, under optimal conditions of temperature 55 °C, pH 8, addition of surfactant Tween 20, and metal ion K2SO4, about 104% size reduction was achieved with average size of 2.3nm. Molecular characterization revealed 98% sequence homology with Bacillus mojavensis. AgNPs exhibited antibacterial activity at concentrations ranging from 0.5 to 2.5 µg/µl against Escherichia coli BTCB03, Klebsiella pneumonia BTCB04, Acinetobacter sp. BTCB05, and Pseudomonas aeruginosa BTCB01 but none against Staphylococcus aureus BTCB02. Highest antibacterial activity was observed at 0.27 µg/µl and lowest at 0.05 µg/µl of AgNPs indicated by zone of inhibition. Conclusively, under optimum conditions, Bacillus mojavensis BTCB15 was able to produce AgNPs of 2.3 nm size and had antibacterial activity against multi drug resistant pathogens.
