Effectiveness of Biolarvicide Extract and Granule Formulation of Cocok Bubu Leaves Against Aedes aegypti
Full text linkDengue Hemorrhagic Fever (DHF), transmitted by Aedes aegypti, remains a major public health concern. This study aims to evaluate the effectiveness of biolarvicides from methanol and acetone extracts of cocok bubu (Elatostema rostratum) leaves and their granule formulations. Extracts and granules were tested at concentrations of 50, 100, 200, and 400 ppm. Granule preparations met standard criteria, including organoleptic properties, active compound content, and dispersion time. The analysis included LC₅₀ and LT₅₀ determination for both extract types. The acetone extract showed greater larvicidal activity (LC₅₀ = 85.67 ppm; LT₅₀ = 51.1 hours) than the methanol extract (LC₅₀ = 112.854 ppm; LT₅₀ = 51.8 hours), both falling into the moderate-to-high toxicity category. Similarly, the granule formulations showed that acetone-based granules (LC₅₀ = 496.941 ppm; LT₅₀ = 51.1 hours) were more effective than methanol-based granules (LC₅₀ = 528.774 ppm; LT₅₀ = 57.3 hours), with moderate-to-low toxicity. These findings indicate that cocok bubu leaf extracts, particularly acetone-based, have potential as effective plant-derived larvicides. Further development of plant-based larvicides may offer safer alternatives to synthetic larvicides in vector control programs
Physicochemical Properties of Pempek Made with Snakehead Fish (Ophiocephalus striatus) Premix Flour
Full text linkSnakehead fish (Ophiocephalus striatus) contains high-quality protein (25.1%) and albumin (6.224%), which supports cell and tissue regeneration. However, its snake-like appearance reduces consumer appeal. This study aimed to determine the optimal formulation of premix flour for pempek production with snakehead fish flour and to evaluate its nutritional content. The research involved five stages: production of fish flour, formulation of premix flour, pempek preparation, organoleptic testing using the hedonic method, and proximate analysis. A total of 15 treatment combinations were tested with four levels of fish flour substitution (10%, 20%, 30%, 40%). The best formulation, based on organoleptic parameters (taste, aroma, texture, color), was 40% snakehead fish flour, 29.2% tapioca flour, 29.2% sago flour, and 1.6% seasoning. Nutritional analysis of pempek from this formulation showed a moisture content of 36.65%, ash 2.08%, protein 24.64%, fat 5.47%, and carbohydrate 31.17%. This study concludes that snakehead fish flour can be effectively used in pempek production to enhance its protein content and nutritional value while maintaining acceptable sensory characteristics

Effectiveness of Desmanthus virgatus Leaf Ethyl Acetate Extract and Antiviral Drugs as Antirabies Based on In Silico Study
Full text linkRabies is a deadly viral disease that has no effective therapy after clinical symptoms appear. This study aims to evaluate the antirabies potential of the dominant compounds in the ethyl acetate extract of Desmanthus virgatus leaves, as well as several antiviral drugs, through an in silico approach. The extract was obtained through maceration and partitioning methods using ethyl acetate solvent, then analyzed using LC-MS, which identified 182 secondary metabolite compounds, and ten dominant compounds were selected for further analysis. These compounds, along with seven antiviral drugs, were docked against the rabies virus glycoprotein (PDB ID: 6LGX) using AutoDockTools 4.2.6 software. The docking results were analyzed based on the values of binding affinity, inhibition constant (Ki), and interaction with active amino acid residues. Quercitrin and quercimeritrin were the dominant flavonoid glycosides in the ethyl acetate extract of D. virgatus leaves that showed binding affinity values of -8.45 kcal/mol and -8.10 kcal/mol, respectively. In addition, bictegravir and tegobuvir showed binding affinity values of -9.17 kcal/mol and -9.05 kcal/mol, respectively. Four compounds indicated potential as antirabies drugs. Pharmacokinetic feasibility tests using Lipinski parameters showed that most of the dominant compounds violated one or more parameters, especially the number of hydrogen bond donors/acceptors and molecular weight. However, such violations were also found in some antiviral drugs that have been used, such as remdesivir and darunavir. These results suggest that D. virgatus leaf extracts contain compounds with promising potential antirabies activity and deserve further investigation through in vitro and in vivo tests

The Independent Curriculum provides flexibility for educators in designing contextual learning that is relevant to the needs of students, so that the selection of essential materials becomes very crucial. This study uses quantitative descriptive analysis with a simple random sampling technique on science teachers in Mataram City. Data was collected through a Likert-scale questionnaire to measure the level of urgency of science materials and the essentiality of aspects of the learning process. The results showed that most of the science materials, such as "Substances and Their Changes", "Life Organization Systems", and "Energy and Its Changes" were categorized as very urgent, with an average score of 3.44. In addition, aspects of the science learning process, such as "science-based problem solving", "science project development", and "science literacy skills", were also considered very essential, with an average score of 3.40. However, there are two materials with a moderate level of urgency, namely "Electricity and Magnetism" and "Human Reproductive System". Meanwhile, only one aspect of learning is considered essential (not very essential), namely "application of science in everyday life". This finding indicates the importance of adjusting the curriculum and learning strategies to ensure optimal achievement of competencies. Recommendations are directed to curriculum developers and educators to focus on materials and aspects of learning that best support students' scientific literacy and 21st-century skills
Identification of Bioactive Compounds in Garlic (Allium sativum L.) with Hypocholesterolemic Potential
Full text linkHypercholesterolemia is a major risk factor for cardiovascular disease, the leading cause of death worldwide. Although statins remain the standard treatment, their long-term use is associated with side effects, sparking interest in safer natural alternatives. Garlic (Allium sativum L.) contains bioactive compounds such as organosulfur compounds (e.g., allicin) and flavonoids (e.g., quercetin and kaempferol), which have been shown to have cholesterol-lowering potential. This study aims to identify bioactive compounds in fresh garlic ethanol extract and powder using liquid chromatography-mass spectrometry (LC-MS), and to evaluate their in vitro anticholesterol activity using the Liebermann-Burchard method. The extracts were prepared using 70% ethanol and tested for their ability to lower cholesterol levels. LC-MS analysis revealed 96 compounds in the fresh garlic extract and 110 compounds in the garlic powder extract. Bioactive compounds such as organosulfur compounds and flavonoids were identified among these compounds. Based on their composition percentages, allicin was more abundant in the garlic powder extract, as were flavonoids such as quercetin and kaempferol, particularly in glycosides. In vitro tests showed cholesterol-lowering effects, with EC₅₀ values of 41,349.08 ppm for the fresh extract and 35,462.29 ppm for the powder extract. Garlic powder extract exhibits higher activity. These findings suggest that garlic, particularly powder form, has potential as a natural cholesterol-lowering agent. Further in vivo studies are needed to confirm its efficacy, mechanism of action, and long-term safety
