Jeruk lemon (Citrus limon Linn.) merupakan tanaman dengan jenis kulit yang memiliki kandungan senyawa fitokimia yaitu flavonoid, terpenoid, tanin dan limonen yang dapat dimanfaatkan sebagai insektisida nabati. Kandungan senyawa kimia tersebut memiliki kemampuan untuk mortalitas nyamuk, dan berperan sebagai racun pernapasan serta racun perut bagi nyamuk tersebut. Tujuan penelitian ini yaitu untuk mengetahui pengaruh dari ekstrak kulit jeruk lemon (Citrus limon Linn.) terhadap mortalitas nyamuk Aedes sp., serta mengetahui potensinya sebagai repellent. Jenis penelitian yang digunakan dalam penelitian ini adalah eksperimen dengan menggunakan rancangan penelitian berupa Rancangan Acak Lengkap (RAL) yang dilakukan dengan menggunakan 3 perlakuan variasi dosis ekstrak kulit jeruk lemon (Citrus limon Linn.) yaitu 25%, 27,5%, dan 30% serta kontrol (+) dan (-). Pengumpulan data dilakukan dengan melihat dan mencatat mortalitas/kematian dari nyamuk Aedes sp. setelah diberikan perlakuan dan mengamati nyamuk yang hinggap pada tubuh mencit dan menghitung jumlah nyamuk yang hinggap menggunakan rumus Daya Proteksi. Data diuji statistik menggunakan Anava Satu Jalur dan dilanjutkan dengan uji BNT (Beda Nyata Terkecil). Hasil penelitian diperoleh nilai Fhitung˃Ftabel yaitu 0,484 pada taraf α=0,05 sehingga H0 ditolak dan H1 diterima. Artinya terdapat pengaruh yang signifikan dari masing-masing perlakuan. Dosis terbaik yang efektif yaitu dosis 30% dengan jumlah nyamuk mati sebanyak 50 ekor. Daya proteksi tertinggi pada konsentrasi 30% sebesar 97,3%, sedangkan daya proteksi terendah pada konsentrasi 25% sebesar 77,1%.

One of the plant groups that dominate coastal vegetation is Spermatophyta, which not only has an ecological function as a coastal protector and erosion prevention, but also has great potential as a medicinal plant. This study aims to explore the diversity and potential of coastal vegetation plants as a source of natural medicine that can be used for traditional and modern medicine. In this study, identification of the types of plants that grow along the coast was carried out. The method used includes collecting plant samples, This type of research is descriptive. The method used is purposive sampling with the line transect technique. Determination of 3 locations as sampling stations at Tanjung Setia Krui Beach, West Lampung. Furthermore, the results of the inventory were identified using the Spermatophyta identification book. The research results found 11 plant species that have the potential as natural medicinal plants, namely kelapa (Cocos sp), sea pandan (Pandanus tectorius), ketapang (Terminalia catappa), tapak liman (Elephantopus scaber), beluntas (Pluchea indica), babandotan/bandotan (Ageratum conyzoides), waru (Hibiscus tiliaceus), krokot (Portulaca oleracea), ornamental beans (Arachis pintoi), butun or keben (Barringtonia asiatica) and katang (Ipomea pes-caprae). The Diversity Index (H’) of higher plants that make up coastal vegetation at Tanjung Setia Krui Beach is 1.061. So it is categorized as moderate, the Dominance Index (ID) of station 1 is 0.112, station 2 is 0.108, station 3 is 0.358. So it is categorized as low. This study provides knowledge about the potential for utilizing coastal vegetation plants as sustainable natural resources, the development of natural medicinal products, especially in the use of natural materials as an alternative treatment.

Dengue Hemorrhagic Fever (DHF) is a disease caused by the dengue virus and transmitted through the bite of the Aedes aegypti mosquito. Early diagnosis is essential to reduce the severity and mortality rate of this infection. Recent studies have shown that mosquito saliva contains specific biomarkers that can be used to detect dengue infection non-invasively. This study uses a systematic literature review method, namely tracing and analyzing various scientific publications relevant to the topic of non-invasive diagnostics for dengue. The results of the study can be concluded that: that mosquito saliva has great potential as a source of biomarkers for non-invasive dengue diagnosis. This method can be a more effective and easily accessible solution, especially in dengue endemic areas. However, to increase its effectiveness, further research is needed in the aspects of developing biomarker-based diagnostic kits, validation in various epidemiological environments, integration of this method in the global health system and regulation of policy makers

Deforestation is a form of environmental change that significantly impacts the ecology of disease vectors, including mosquitoes. Changes in forest cover can influence mosquito behavior, particularly biting patterns and host preferences, which have implications for increasing the risk of vector-borne diseases in humans. The purpose of this article is to systematically review research findings from the past three years related to changes in mosquito biting patterns due to deforestation. The method used was a systematic review of scientific articles published between 2022 and 2026, which discussed the relationship between deforestation, habitat change, and mosquito biting behavior. The results indicate that deforestation contributes to increased mosquito biting activity on humans, changes in peak biting times, and a shift in host preference from animals to humans. The conclusions of this review confirm that deforestation plays a significant role in changing mosquito behavior and has the potential to increase the risk of vector-borne disease transmission.

Mosquito-borne diseases caused by Aedes spp., including dengue, chikungunya, and Zika, remain major public health concerns in tropical countries. This study aimed to integrate breeding place surveys and the preparation of Aedes spp. developmental-stage specimens as an innovation in Living Lab-based parasitology learning. A descriptive-exploratory study was conducted at Campus 3 of Universitas Muhammadiyah Metro using a Living Lab approach. Potential breeding habitats were surveyed, and mosquito specimens at different developmental stages (eggs, larvae, pupae, and adults) were collected, identified, and prepared as entomological specimens. The quality of the specimens was evaluated based on specimen integrity, morphological clarity, neatness, and ease of identification. The survey examined 75 water-holding containers and identified eight breeding sites positive for Aedes larvae, predominantly in aquatic plants and water storage containers. Morphological observations successfully documented key characteristics of all developmental stages. The prepared specimens demonstrated good overall quality, with clear diagnostic structures that facilitated identification and learning activities. The integration of breeding place surveys and specimen preparation provided authentic learning experiences, enhanced students’ practical skills in medical entomology, and produced sustainable learning resources. This approach can serve as an innovative model for parasitology education and vector surveillance programs.Keywords: Aedes spp.; breeding place; entomological specimen; Living Lab; parasitology learning.
