Abstract

Jambi is one of the provinces in Sumatra which has the potential of abundant natural resources. This must be based on the principles of sustainability, harmony, and best use, as well as the utilization of natural resources in the form of land and water as one of the basic assets of national development to achieve economic and ecological balance. Human activities by building buildings or other facilities without taking into account the area of ​​open land have resulted in reduced rainwater catchment areas. Another cause is the disposal of garbage in the flow of water bodies, so that water cannot flow smoothly which in turn results in overflow of water. Rainwater that becomes run off and garbage that is thrown carelessly, is then managed in a way so that it can be beneficial for the environment and humans themselves. Therefore, the idea of ​​making biopore infiltration holes arose where the main ingredient was organic waste. Partner priority problems are frequent flooding during the rainy season; the surrounding community does not have special skills to be able to make biopores as infiltration holes. The activity will be carried out using structured mentoring and training methods for making biopore infiltration holes. It is hoped that from this activity Partners can make biopori, activity videos and media article.

Abstract

The phenolic chemicals found in water extract of Merkubung bark (WEMB) can be employed as corrosion inhibitors. The corrosion inhibition mechanism by WEMB can be studied using an adsorption isotherm model. The Langmuir adsorption isotherm model has an R2 value that was closest to 1 one compared to the Freundlich, Temkin, Florry Huggins, and Frumkin adsorption isotherm models, as shown by an analysis of the adsorption isotherm model. Due to the interaction between the WEMB and the steel surface, the adsorption isotherm model reveals that the inhibitor of WEMB on the surface coating of mild steel tends toward chemisorption.

Abstract

Burns are injuries that can be caused by heat (fire, hot liquids/fats, hot vapors), radiation, electricity, or chemicals. Coffee mistletoe leaves (Loranthus ferruginous Roxb) are one type of plant that contains secondary metabolite compounds, such as flavonoids, tannins, saponins, alkaloids, and phenolics, which play a role in the burn healing effects. This research was conducted using an experimental research method with a Completely Randomized Design (CRD) and a post-test only control group design approach. A total of 25 rats were divided into five treatment groups for the study. The groups included a positive control group treated with Bioplacenton gel, a negative control group treated with yellow vaseline, and three experimental groups treated with different concentrations of ethanol extract of coffee mistletoe leaves. The concentrations used were 5% (P1), 10% (P2), and 15% (P3). The burn healing activity and hydroxyproline content were observed as outcome measures. The data were presented as mean ± SD and analyzed using one-way ANOVA. Subsequently, Duncan's multiple rank test was performed to determine any significant differences. A significance level of p<0.05 was considered to define statistically significant results. The results of the study showed that ethanol extract of coffee mistletoe leaves has an effect as a burn treatment, with the best concentration found at 15% concentration, which had a healing percentage of 62.5%, although its effectiveness did not exceed that of the positive control group (72,48%). The hydroxyproline content of the coffee mistletoe leaf extract group demonstrated significant difference when compared to control negative groups, especially P1 group (53.62±6.52 μg/mL), and statistically not different with positive control (64.34 ±6.02 μg/mL). For the P2 and P3 groups, the hydroxyproline content were increased but did not reach significant value. Wound-healing activity owing to its richness in various effective chemical compounds present in the extract such as phenolics, saponin, flavonoid and alkaloid. Further investigation is necessary to identify and understand these additional components and their mechanisms of action in the healing process.

Abstract

Cadmium (Cd) is a toxic heavy metal with the active property of reacting with other components so that cadmium residues can quickly enter the food chain and cause cardiovascular, kidney, and cancer diseases. The purpose was to synthesize the magnetite mercaptosilicate ion imprinted polymer adsorbent material by forming Ion-Imprinted Polymer as a template, to analyze the characterization results using XRD and SEM-EDS, and to determine the adsorption test results for Cd metal ions. The results of the characterization of XRD show that there is a broad peak at a diffraction angle of 2θ= 20-220 with an amorphous structure, which is silica, and there is a high peak at a diffraction angle of 2θ= 35.55140 which indicates magnetite. The results of SEM analysis with magnifications of 500x, 1000x, and 5000x showed that the surface morphology of the particles was not uniform. For the EDS results, it can be seen that the components of the magnetite mercaptosilicate ion imprinted polymer material are elements C, O, Si, S, and Fe, with a mass percentage of 25.0%; 41.2%; 29.9%; 3.28% and 0.8%. The results of the adsorption test for the Magnetite-IIP-Mercaptosilika Material were able to adsorb Cd ions with the highest adsorption capacity of 10.536 mg/g at a concentration of 100 mg/L. Then the selectivity coefficient value of the Ion Cd metal ion is 2.32 greater than 1, indicating that the selectivity of the magnetite mercaptosilicate ion imprinted polymer material is much higher for Ion Cd metal ions than for Cu and Cr ions with a selectivity coefficient of 0.1 and 0.26.
