Abstract

Blumea balsamifera is one of the Asteraceae family known as Sembung leaves. B. balsamifera is often used in traditional medicine. This study aims to evaluate the potential biological activity of Sembung leaves (Blumea balsamifera) through the determination of total tannin levels and toxicity tests using the Brine Shrimp Lethality Test (BSLT) method. Leaf extraction is carried out by the maceration method using methanol solvent. The total tannin content was determined using the colorimetric method with the Folin-Ciocalteu reagent, resulting in a tannin content of 358.04 mg TAE/g of extract. The toxicity test showed an LC50 value of 56.58 μg/mL, which indicated that the methanol extract of B. balsamifera leaves was toxic. These results suggest that the high tannin content correlates with the toxicity properties of the extract, which has the potential to be further developed as a therapeutic agent.

Abstract

The spring in Meurandeh is a source of water that is widely used by residents as drinking water and natural medicine. This water is also often consumed raw without being processed. This study aims to determine the quality of the springs in Meurandeh. This type of research is descriptive qualitative with observational data collection methods. The data collected in this study was compiled, explained, and analyzed. Parameters tested include physical, chemical, and biological parameters. Physical parameters include odor, color, dissolved solids, and temperature. Chemical parameters include pH, hardness, iron, fluoride, DO, nitrate, nitrite, cyanide, detergent, and manganese. While the biological parameters are total Coliform and E.coli. Measurements of odor, dissolved solids, DO, temperature, and pH were carried out directly in the field. Tests for hardness, iron, fluoride, nitrate, nitrite, cyanide, detergent, manganese, total coliform, and E. coli were carried out at the Testing Laboratory of the Banda Aceh Center for Standardization and Industrial Services. The results showed that 14 of the 16 parameters tested met the requirements for drinking water quality according to the Minister of Health of the Republic of Indonesia Number 492 of 2010. Meanwhile, the other two did not meet these requirements, namely pH and total Colliform.
