Abstract

Mealybug (Hemiptera:Pseudococcidae) is a polyphagous pest that attacks various horticultural crops. Its reproduction rate is very rapid; in tropical regions, the life cycle lasts about 19–25 days at temperatures of 28–32°C. Its natural enemies include predators and parasitoids. This study aimed to determine the number of colonies and individuals of the whitefly pest on mango plants. The research was conducted from July to November 2025 in Gampong Cot Mesjid, Lueng Bata District, Banda Aceh City, Aceh Province. The method used was qualitative with a descriptive approach, and data were collected through field observations. From five observed samples, the distribution of whitefly colonies on mango plants was found to be higher compared to the number of natural enemy individuals. The results showed a positive relationship between the number of whitefly colonies and the number of natural enemies; however, the effectiveness of natural enemies in suppressing pest populations remained low. Ecologically, maintaining a balance between pest and natural enemy populations is necessary. Economically, biological control needs to be strengthened to minimize losses caused by pests without dependence on chemical pesticides.

Abstract

The availability of clean water is still a serious challenge, especially in rural areas and developing areas. This study aims to examine the innovation of natural-based water purification technology through the use of avocado seed peel as a natural coagulant combined with Solar Water Disinfection (SODIS). The method used is a literature review by analyzing scientific articles in the last ten years related to the effectiveness of avocado seed shells and SODIS in water treatment. The results of the study show that avocado seed shells contain bioactive compounds such as tannins, flavonoids, and polyphenols that function as coagulation and adsorption agents, so that they are able to reduce turbidity, color, and organic and heavy metal content in water. Meanwhile, SODIS technology has been proven to be effective in reducing microbiological contamination, particularly pathogenic bacteria, through the mechanism of UV-A radiation and temperature increase. The combination of these two methods has been proven to complement each other, where pre-treatment with avocado seed peel reduces the turbidity of water so that the penetration of UV rays in the SODIS process is more optimal. The integration of simple, cheap, and environmentally friendly methods has great potential to be applied as an alternative to sustainable clean water supply while supporting the achievement  of the Sustainable Development Goals (SDGs) related to clean water and sanitation.

Abstract

This study aims to describe the leadership of female principals in public junior high schools (SMP Negeri) in Banda Aceh in developing adaptive, inclusive, and character-based schools. This qualitative reflective study employed in-depth interviews, participant observation, and document analysis. The findings reveal that female principals in Banda Aceh demonstrate collaborative and value-based leadership styles rooted in Islamic spirituality and Acehnese cultural values. Their leadership emphasizes empathy, morality, and professionalism, which foster safe, harmonious, and inspiring school environments. The research concludes that female leadership contributes significantly to school transformation, not only by improving academic and managerial performance but also by strengthening the moral and social character of school communities.
