Abstract

The Garuga floribunda (Garuga floribunda Decne) plant is one of the species known for its various medicinal properties. This research aims to investigate the inhibitory activity of α- glucosidase and α-amylase enzymes and to determine the optimum concentration of the methanol extract of Garuga floribunda leaves as an antidiabetic agent. The leaves extraction is obtained through an extraction process using methanol as the solvent and tested for itsinhibitory activity against the α-glucosidase enzyme using the p-nitrophenyl-α-D- glucopyranoside (p-NPG) substrate and the α-amylase enzyme using the DNS (3,5- dinitrosalicylic acid) substrate. The method is UV-Vis spectrophotometry. The Phytochemical tests of this plant reveal the presence of flavonoids, alkaloids, saponins, tannins, steroids, and terpenoids. The inhibition test results show that the methanol extract of Garuga floribundaleaves exhibited significant inhibitory activity against both enzymes. The highest inhibition percentage against the α-glucosidase enzyme is 91.09%, indicating very high antidiabetic activity. Meanwhile, the inhibition against the α-amylase enzyme is 7.56%, showing no significant antidiabetic activity. The optimum concentration for inhibiting both enzymes is 1000 ppm.

Abstract

Sacha inchi (Plukenetia volubilis Linneo) is a plant from the Euphorbiaceae family known for its green star-shaped fruit and brown seeds. This plant has high nutritional value and significant antioxidant activity (Nuha and Sriwidodo 2022). This study aims to identify secondary metabolite compounds and determine the total phenolic content of the methanol extract of Plukenetia volubilis Linneo leaves. The samples were extracted using the maceration method, then phytochemical tests and total phenolic content analysis were carried out using the Folin-Ciocalteu method (Sari et al. 2021). The results of the phytochemical test showed that the methanol extract of sacha inchi leaves contained secondary metabolite compounds such as alkaloids, flavonoids, saponins, and tannins. The total phenolic content obtained from the extract was 19.94%, which indicates the potential for high antioxidant activity. The results of this study indicate that sacha inchi leaves have the potential to be developed as a source of natural bioactive compounds that are beneficial to health.

Abstract

This study aims to determine how nano chitosan is produced through the ionic gelation method. The process of making nano chitosan is carried out using variations in chitosan concentrations of 1%, 5%, and 10%, and using a magnetic stirrer. Morphological tests were carried out using Scanning Electron Microscopy (SEM) to observe the shape and size of the particles formed. The addition of TPP (Trisodium Tripolyphosphate) as a crosslinker and certain surfactants are used to increase particle stability. Treatment for ±2 hours showed optimal results in terms of a more homogeneous particle size distribution. Based on the results of SEM observations, it is known that increasing the concentration and time settings and the use of appropriate surfactants can reduce wrinkles in nano chitosan particles. The particle size obtained is in the range of 278–350 nm. Thus, the ionic gelation method has proven effective in producing uniform nano chitosan and has good morphology for further applications.

Abstract

The utilization of clam shells as adsorbents has attracted considerable attention due to their ability to adsorb contaminants such as heavy metals, hazardous substances, and oil. Clam shells, which are composed mainly of calcium carbonate (CaCO₃), possess a porous structure that favors adsorption. Calcium carbonate imparts alkaline properties that neutralize acidic effluents and promote the formation of precipitates. Physical and chemical modifications can enhance the surface area and porosity of the shell, thereby enlarging the active sites for contaminant sorption. Clam shells heavy metals such as Pb, Cd, Hg, organic substances and can be used for oil spill remediation due to their hydrophobic and oleophilic properties. The calcination process converts the shells into a material that contaminants such as TSS, COD, and BOD. This utilization not only mitigates pollution but also creates opportunities for adsorbent products with economic value, especially in coastal areas where shell waste is abundant. However, this application must take into account ecological and health impacts, as overharvesting and non-environmentally friendly processing can damage the ecosystem. A sustainable approach with environmentally friendly regulations and technologies is essential to maximize the benefits of clam shells as adsorbents.

Abstract

Indonesia, as an archipelago, has significant agricultural potential, but its optimal utilization requires balancing rice production volume with the available harvest area. This study analyzed the contribution of harvested area to rice production in Gorontalo Regency using linear regression analysis. The data used included the harvest area and the amount of rice production during the period 2018–2024, sourced from the Central Bureau of Statistics (BPS) of Gorontalo Province. The independent variable in this study was the amount of rice production (tonnes), while the dependent variable was the area of harvest (Ha). The analysis results revealed a very strong linear relationship between the two variables, with a correlation coefficient (R) of 0.8437 and a coefficient of determination (R²) of 0.7119. The regression equation indicated that an increase in rice production by 4.8891 tonnes corresponded to an increase in the harvested area by 1 hectare. The model significance value of 0.017017 indicated that the regression model was statistically significant. This finding demonstrates that the amount of rice production significantly affects the area of harvest, and the model can serve as a predictive basis for planning agricultural sector policies in Gorontalo Regency.
