Abstract

Ocimum sanctum has been widely investigated as a source of bioactive compounds with potential applications in vector control. This study examined the phytochemical profile of O. sanctum essential oil and evaluated the physicochemical characteristics and preliminary adulticidal activity of its nanoemulsion formulation against Aedes aegypti. Essential oil obtained by hydrodistillation was formulated into an oil-in-water nanoemulsion and subsequently characterized through physicochemical and stability testing. Phytochemical screening confirmed the presence of alkaloids, flavonoids, terpenoids, steroids, and other essential oil constituents. The nanoemulsion exhibited a homogeneous appearance, a pH of 6-7, a transmittance of 91-94 %, an adhesion time of 10-14 s, and a spreadability of 9-15 cm. Particle characterization confirmed the formation of nanoscale droplets with acceptable distribution profiles. No signs of skin irritation were observed during the preliminary safety assessment. Adulticidal testing demonstrated transient knockdown effects but limited mortality after 24 h of observation. These findings indicate that O. sanctum essential oil can be formulated into a physically stable nanoemulsion; however, further optimization is required to improve biological performance and residual activity before practical public health applications can be considered.

Abstract

Children in Indonesia spend around 7-8 hours at school; therefore, comprehensive child safety protection at schools is needed, and one of them is done through implementing the Disaster Preparedness and Safety Schools (SSSB) program. The authors carried out prior research about developing the Disaster Preparedness and Safety Schools model. To complement the development of the SSSB program done in the previous study (the first stage), this research (the second stage) was carried out. This research aimed to develop key indicators and measuring tools for assessing teacher knowledge about child safety education to support the implementation of the SSSB program. This research applied a literature study and a mixed-method approach with a mixed exploratory sequential design. The analysis of key indicators of teacher knowledge about child safety education was done qualitatively and analyzed using content analysis techniques. The validity and reliability of the instrument were assessed quantitatively. The Cronbach’s Alpha value was 0.868, indicating that the measurement instrument is valid and has good reliability. These indicators are very important for building school resilience from multi-disaster risks in terms of teacher knowledge preparation.
