Abstract

Hyperuricemia is a metabolic disorder because of excessive uric acid production. The high prevalence of hyperuresemia in the world, especially in Indonesia makes the research of antihyperurisemia drugs very needed today. The purpose of this study was to determine the activity of water infusion extract from celery stems and leaves to inhibited xanthine oxidase enzyme. Xanthine oxidase enzyme plays a role in change of hypoxanthine to xanthine and then becomes uric acid. The activity of xanthine oxidase enzyme was determined by UV spectrophotometry method and using xanthine substrate. Absorption at 290 nm indicates the presence of a uric acid product from xanthine oxidation by the xanthine oxidase enzyme. Infused extract which has the smallest absorption at 290 nm showed a better inhibitory ability of the xanthine oxidase enzyme because the change of xanthine substrate to uric acid is inhibited. The result showed the celery stems water infusion extract had better inhibition activity than celery leaves water infusion extract. The best inhibition percentage of celery stems water infusion was 90,25%, while the celery leaves water infusion was 69.07% both of at 20% concentration. The type inhibition of celery stems water infusion extract to xanthine oxidase enzyme showed an uncompetitive inhibition type because showed change in Km and Vmax values. Km and Vmax values before the addition of water infusion of celery stems were 104.33 ppm and 3.83 U/mL respectively changed to 74.49 ppm and 2.69 U/mL after the addition of extract.

Abstract

Microplastics are a form of new pollution that the Indonesian people are not aware of. The factors for the entry of microplastics into pond waters are water sources, anthropogenic activities, and pond cleanliness. The purpose of this study was to determine the abundance of microplastics, the color and shape of microplastics, and the types of microplastic polymers found in sediment, water, and the digestive tract of milkfish (Chanos chanos) in Sidoarjo ponds. The average abundance of microplastics in sediment samples obtained from semi-intensive ponds is 300 particles per 50 grams, while the sediment samples from traditional ponds are 613 particles per 50 grams. The average abundance of microplastics in the semi-intensive pond water samples was 2.1 particles per 20 liters and in traditional ponds was 2.3 particles per 20 liters. The average abundance of microplastics in the milkfish (Chanos chanos) samples from the Semi-Intensive Pond was as many as 6 particles per tail, while the Traditional Pond had 9.5 particles per tail. In this study, four colors of microplastics were found, namely blue, black, red, and transparent, while the microplastics obtained were fiber, fragment, and filament. The types of microplastic polymers encountered in this study were dominated by polyamide or nylon polymers. In sediment samples from both ponds, we found the presence of Polyamide or Nylon polymers, namely Polystyrene and Polyamide or Nylon, and in the digestive tract of milkfish (Chanos chanos), namely Polyamide or Nylon.

Abstract

Diabetes is a health problem that exists throughout the world, especially in Indonesia. Based on data compiled from the International Diabetes Federation (IDF) in 2017, people with diabetes in Indonesia reached 10.3 million people, and if not handled properly it is suspected that there will be an increase to 21.3 million people in 2030. Curcumin analog compounds can used for the treatment of diabetes by inhibiting the enzyme α-glucosidase. The curcumin analog compound used in this study was synthesized from 4 methoxybenzaldehyde with cyclopentanone which was then called the CA2 compound. The α-glucosidase enzyme used in this study was obtained through extraction of weathered rice with an optimum pH of 4.5 and the enzyme extract fraction used was fraction II which had the highest activity compared to fractions I and III. The results showed that the values of the kinetic parameters Km and Vmax of the extracted α-glucosidase enzyme were 1.53 mM and 0.03 U/mL, respectively. The Km kinetic parameter value changed to 1.66 Mm while the Vmax value did not change when the α-glucosidase enzyme was inhibited by CA2 compound, so that the type of inhibition shown by CA2 compound was competitive.

Abstract

Buah melon (Cucumis melo L.) kaya nutrisi, namun produksinya rentan terhadap serangan hama seperti kutu kebul. Penggunaan perangkap likat menjadi solusi alternatif untuk mengendalikan hama tersebut tanpa terlalu mengandalkan insektisida sintetik. Penelitian ini secara mendalam mengevaluasi tingkat kerusakan yang ditimbulkan oleh serangan hama kutu kebul (Bemisia tabaci) terhadap tanaman melon, sekaligus menguji efektivitas perangkap lengket dengan memvariasikan warna (hijau, kuning, coklat, putih) dan tinggi (antara 50 hingga 200 cm). Eksperimen dilakukan di dalam rumah kaca dengan menerapkan Rancangan Acak Lengkap faktorial karena kondisi lingkungan yang tidak seragam. Hasil penelitian menunjukkan bahwa perangkap lengket berwarna kuning mampu secara efisien mengurangi populasi kutu kebul hingga mencapai 6.307 individu. Meskipun demikian, penyesuaian tinggi perangkap tidak memberikan pengaruh signifikan (Sig=0,061) terhadap pengurangan populasi kutu kebul, namun tinggi perangkap ternyata dipengaruhi oleh pertumbuhan tanaman. Meskipun perangkap kuning terbukti efektif dalam lingkungan yang seragam, analisis Two-Way ANOVA mengungkap nilai Signifikansi yang menunjukkan hasil yang lebih kompleks. Variabel abiotik seperti iklim, cahaya, dan kelembapan ternyata memegang peran penting dalam memengaruhi efikasi perangkap. Penelitian ini memberikan wawasan mendalam tentang strategi pemilihan perangkap lengket untuk mengendalikan populasi kutu kebul pada tanaman melon, sambil menyoroti pentingnya mempertimbangkan faktor lingkungan dalam pengembangan strategi pengendalian hama yang efektif.

Abstract

Breast cancer is one of the causes of women’s death. Estrogen-α receptors are one of the targets for breast cancer treatment because it plays a role in cancer cell proliferation. Several studies have stated that Flavonoid compounds have high activity in inhibiting the growth of breast cancer cells. This study aims to inhibit polyphenolic compounds in pomegranate peel (gallic acid, cafeic acid, ellagic acid, and chlorogenic acid) against estrogen receptors-α through molecular docking. The 3D structures of the polyphenolic compounds were obtained from the PubChem database and the estrogen-α receptors from the Protein Data Base. Molecular docking simulations were carried out using AutoDock Vina and supporting software such as Biovia Discovery Studio Client 4.1, AutoDockTools 1.5.6, PyMOL, and LigPlot. The results showed that the four polyphenolic compounds had a better potential to inhibit estrogen-α receptors than tamoxifen. The inhibitory potential is evidenced by the low affinity of ligand-protein binding energy (approximately -5.4 to -9.0 kcal/mol). The phenol group of polyphenolic compounds can strengthen the ligand-protein interactions through hydrogen bonds with the active site of ER-ꭤ proteins. Hydrophobic and π-π stacking interactions between polyphenolic and the active site of proteins also support the inhibition potential of polyphenolic compounds. The conclusion is that the polyphenolic compounds in pomegranate peel have the potential as breast anticancers.

Abstract

This study aims to develop a peel-off gel mask formulated from orange peel eco-enzyme solution and its physical characteristics and antibacterial activity against Staphylococcus epidermidis. The resulting gel mask has organoleptic characteristics of transparent brownish color, thick gel consistency, and fresh sour-sweet aroma. Physical characteristic tests showed that the gel mask meets pharmaceutical requirements, namely: pH value 4.5-6.5, spreadability 5-7 cm, and drying time 15-30 minutes. The mask showed good homogeneity without aggregates, although it was a little difficult to peel off, but it was not easily torn, and had stable thermodynamic stability. Antibacterial tests revealed that the peel-off gel mask made from orange peel eco-enzyme was effective in inhibiting the growth of Staphylococcus epidermidis. The diameters of the inhibition zones of the P1, P2, and P3 masks were 2.5 ± 0.5 mm, 2.1 ± 0.35 mm, and 1.5 ± 0.5 mm, respectively. These results indicate the potential of eco-enzymes from orange peel as active ingredients for peel-off gel mask formulation for skin care, especially in inhibiting acne-causing bacteria.
