Abstract

Syzygium aromaticum contains bioactive compounds that may serve as natural alternatives to synthetic mosquito control agents. This study aimed to evaluate the mosquitocidal activity of stem, leaf, and bud extracts of S. aromaticum, formulated as vaporizer mats, against Aedes aegypti and to identify potential molecular targets of the major compounds in these extracts through computational analysis. Volatile extracts from stems, leaves, and buds were prepared by ethanol maceration and formulated into vaporizer mats at concentrations of 0.5% and 1%. A total of 525 adult A. aegypti (F330 strain) were exposed under controlled laboratory conditions in accordance with WHO guidelines. Mortality, LT50, and LT90 values were recorded after exposure. Molecular docking was performed against odorant-binding protein AaegOBP1 and pyruvate kinase (PK1), followed by molecular dynamics simulation. Among all treatments, bud extract at 1% produced the highest mortality (33%), compared with 2% in the negative control. LT50 and LT90 values for this treatment were 1.468 minutes and 50.543 minutes, respectively, indicating prolonged biological activity. Docking analysis showed that β-caryophyllene had the strongest affinity toward AaegOBP1 (-8.4 kcal/mol), while chavicol showed the strongest interaction with PK1 (-6.5 kcal/mol). Molecular dynamics simulation confirmed stable ligand-receptor interactions with RMSF values below 3 Å. These findings indicate that S. aromaticum bud extract has moderate mosquitocidal potential in vaporizer mat formulation and may act through olfactory disruption and metabolic interference in A. aegypti.

Abstract

Carbon dioxide emissions from burning fuel oil have been increasing, resulting in increasingly severe climate change. The use of microalgae as raw materials for biofuel production is an environmentally friendly alternative. Microalgae Chlorella sp. can be sustainably converted into alternative biofuels. Fishery liquid waste, such as that resulting from fish farming and fish processing, can be used as a nutrient medium for microalgae. This study aimed to analyze biomass production from Chlorella sp. using fishery waste in an algae reactor. The working principle of fisheries wastewater processing is related to microalgae in the reactor. The surface of the media forms a biological layer that breaks down organic compounds in the air, thereby reducing the organic content. The compounds resulting from metabolic processes are in the form of solids and gases. The results show that the bioethanol produced from the thermostat Chlorella sp. with fishery waste media can produce 20,000 L/ha. Microalgae contain approximately 20-50% dry weight of carbohydrates, which can be converted into bioethanol. Chlorella sp. can reduce chemical oxygen demand and ammonia by up to 70% by converting carbon dioxide into carbohydrates, fats, and proteins. The application of bioconversion to all companies in the fisheries sector will provide benefits and help the government reduce fossil fuel subsidies.

Abstract

Polisakarida Ganoderma applanatum memiliki sifat antioksidan sebagai respon biologis yang kuat untuk terapi kanker. Penelitian ini menguji potensi ekstrak polisakarida G. applanatum terhadap kadar MDA dan Bax pada tikus (Mus musculus) yang diinduksi DEN. Tikus betina galur DDY dibagi secara acak menjadi 4 kelompok (n=6). DEN diberikan secara intraperitoneal dua kali seminggu, kemudian doxorubicin sebagai kontrol positif dan ekstrak polisakarida sebagai perlakuan selama satu bulan secara oral. Metode penelitian dilakukan dengan membandingkan KN yang diberi air; K- yang diberi DEN 100 mg/kg BB; K+ yang diberi DEN 100 mg/kg BB dan doksorubisin 10 mg/kg BB; dan P yang diberi DEN 100 mg/kg BB dan ekstrak polisakarida G. applanatum 150 mg/kg BB. Dari analisis statistik uji ANOVA yang dilanjutkan dengan uji Duncan, diperoleh bahwa pemberian ekstrak polisakarida G. applanatum dibandingkan dengan K- tidak menunjukkan perbedaan bermakna kadar MDA dan Bax. Data hasil percobaan sebagai berikut: KN menunjukkan kadar MDA sebesar 1,62±0,28 nmol/mL dan Bax 4,41±2,14 ng/mL. Kadar MDA K- sebesar 1,58±0,11 nmol/m dan Bax 3,91±1,84 ng/mL. Kadar MDA K+ sebesar 1,75±0,21 nmol/mL dan Bax 4,30±1,61 ng/mL. Kadar MDA P sebesar 1,74±0,29 nmol/mL dan Bax 2,28±1,27 ng/mL.
