Abstract

Background: Stingless bee honey is recognized for its therapeutic value, which is attributed to a diverse array of bioactive compounds.Objective:  This study aimed to compare the chemical profiles of honey from Tetragonula laeviceps and Itama sp. using gas chromatography-mass spectrometry (GC-MS), focusing on antimicrobial constituents. Methods: Honey samples were collected from Bali, Indonesia, and analyzed using GC-MS. Compounds were identified through spectral matching with established libraries, and primary constituents were compared based on relative abundance.Results:  T. laeviceps honey showed a high concentration of the rare sugar allose (7.6%), azulene (1.02%), and octadecanoic acid (2.07%), whereas Itama honey exhibited elevated levels of levoglucosan (5.35%), aromatic esters, and 3-methyl-2-furylacetone (2.58%). Notably, 5-hydroxymethylfurfural (HMF), known for its antimicrobial properties, was present in both samples at comparable levels (1–2%).Conclusions: The metabolite variations between the two species reflect differences in foraging and resin collection behavior, influencing honey bioactivity. The unique profiles suggest that both types of honey possess valuable antimicrobial potential and could serve as sources for developing novel anti-infective agents.

Abstract

Background: Dengue fever remains a major public health concern in Gianyar Regency, Bali, with rising incidence strongly associated with Aedes aegypti as the primary vector. School environments are critical settings for early prevention due to children’s vulnerability and the presence of potential mosquito breeding sites. Integrating vector control education with environmental management is therefore essential to reduce dengue risk and promote sustainable behaviors.Objective: This program aimed to enhance knowledge and practical skills of students and teachers at Genta Saraswati Elementary School, Gianyar, regarding Aedes aegypti vector control and organic waste management through composting and vermicomposting.Method: The Community Partnership Program (PKM) was implemented through interactive education on Aedes aegypti biology, dengue prevention, identification of breeding sites, and hands-on composting and vermicomposting training using a Montessori-based experiential learning approach. Program effectiveness was assessed using pre- and post-tests.Result: Participants’ knowledge increased significantly, with post-test scores exceeding 70%. Simple composting and vermicomposting facilities were successfully established and utilized as learning media.Conclusion: Integrated vector control education and composting training effectively improved health awareness and environmental responsibility in a school-based setting. Keywords: Dengue prevention; vector control; composting;
