Abstract

Balakacida leaves (Chromolaena odorata L) are plants known for their allelopathic properties, which can be utilized as natural herbicides. Empirically, they are used as wound healing agents, mouthwash, anti-diarrheal, antimicrobial, and anti-inflammatory medicines. The leaves are processed by squeezing them to extract their liquid, which is then applied to skin wounds for treatment (Marianne, 2014). Flavonoid components in balakacida leaves have antimicrobial effects. The focus of this research is to determine the IC50 value of balakacida leaves and characterize their antioxidant ability. Multi-step maceration using polarity-based solvents (n-hexane, ethyl acetate, and ethanol) is employed for extraction. The DPPH technique is utilized to evaluate antioxidant capacity. Phytochemical analysis has revealed active secondary metabolites with antioxidant properties in the plant, including tannins, flavonoids, alkaloids, and steroids. The IC50 values for n-hexane, ethyl acetate, and ethanol extracts are 35.58, 14.24, and 12.73 ppm respectively, indicating very high antioxidant activity. According to Fitrah (2017), crude balakacida leaf extract exhibits antioxidant effects. These effects are attributed to the high content of flavonoids, which possess antioxidant activity capable of inhibiting the oxidation process.

Abstract

The utilization of kijing clam shells as raw materials for chitosan production is one of the efforts to reduce kijing clam shell waste. This study is an experiment aimed at determining how to synthesize carboxymethyl chitosan (CM-Ch) and carboxymethyl chitosan-tripolyphosphate (CM-Ch-TPP), as well as the influence of pH and concentration of CM-Ch and CM-Ch-TPP on the adsorption of Cu(II) metal ions. The results showed that chitosan had a degree of deacetylation (DD) of 76%. Synthesized CM-Ch had characteristic functional groups at peaks 1610.56 cm-1 and 1425.4 cm-1. In the synthesized CM-Ch-TPP, there were functional groups at the peak of P=O stretch vibration and P-O stretch vibration at wave numbers 1213.23 cm-1 and 11,53.43 cm-1 in kijing. It is concluded that CM-Ch and CM-Ch-TPP have the ability to adsorb Cu(II) metal ions at pH 10 with concentrations ranging from 50 to 150 ppm.     The utilization of kijing clam shells as raw materials for chitosan production is one of the efforts to reduce kijing clam shell waste.

Abstract

The addition of ascorbic acid and borax to food and drinks if it exceeds the threshold limit can have dangerous effects on consumers. This research aims to create a simple and fast but accurate method for analyzing ascorbic acid and borax, using purple sweet potato extract as a colorimetric sensor and quantitative analysis using digital images. The results of the digital image have an accuracy of 99% with LOD (Limit of Detection) of 1.96% and LOQ (Limit of Quantity) with a value of 6.53% for ascorbic acid. As for borax, the LOD is 0.54% and the LOQ is 1.78%. Semi-quantitative tests for ascorbic acid and borax in food and drinks can be carried out using a cotton test kit. The wet noodle food sample tested (purchased from around the Bengkulu University campus) was proven not to contain borax because there was no color change. However, the packaged drink tested positive for ascorbic acid as indicated by a color change from purple to pink.

Abstract

In the seas of Lampung, a kind of brown macroalgae known as Padina australis is commonly seen.. Padina australis is widely used in the food industry as a gelling agent, emulsifier, thickener, stabilizer and also in the medical industry. The content of phytochemical compounds that can be developed as phytopharmaceutical agents is one of them as antioxidants. The aim of this study was to analyze the phytochemical content and potential antioxidant activity of the macroalgae Padina australis. The method used was extraction by maceration in 70% ethanol as a solvent. The phytochemical test was performed qualitatively by a color reagent test. The FTIR test was performed to analyze the functional groups of the active ingredients, while the antioxidant test used the DPPH (1,1-diphenyl-2-picrylhydrazil) method. The results obtained show that the ethanol extract of Padina australis contains chemical compounds such as saponins, steroids, tannins, alkaloids, and flavonoids. Padina australis extract shows its potential as an alternative source of natural antioxidant compounds because it is able to reduce free radicals with an IC50 value of 407.96 ppm, which is classified as very weak antioxidant activity. Further research needs to be done to obtain other concentration doses so as to get the best antioxidant activity results that can be developed clinically for health products.

Abstract

Hot springs can be explored for geotourism activities. Geotourism is part of the main field in geology that can contribute to sustainable development. Therefore, hot springs are explored to determine their potential based on their physical and chemical properties. There were three places studied, namely Way Sulfur Kalianda baths, hot springs in Natar, and hot springs in Banjit, Way Kanan. The physical and chemical properties of hot springs measured in situ include total dissolved solids, dissolved oxygen, pH and temperature, while total metal concentrations are determined using ICP-AES. The measured pH value ranged from 5.2-8.1, the average measured temperature ranged from 37-52 °C. The highest and lowest DO values were 9.1 mg/L and 5.5 mg/L respectively. The average TDS and TSS values at the three sample locations were 3620 mg/L and 16.7 mg/L respectively. The highest concentrations of the metals Al, Ba, Cu, K, Ni, Pb are found in Natar, South Lampung, while the highest concentrations of B, Co, Li, Na are in Way Kanan, North Lampung. The highest concentrations of Mg, Mn, Ca are found in Way Sulfur, Kalianda, South Lampung. Concentrations of other metals were generally low and similar at the hot spring sample points studied. With the high content of harmless minerals in hot springs, hot springs can be explored for geotourism activities.
