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.

Abstract

Barus District has long been known as an important trading port on the west coast of Sumatra and historically served as a gateway for the spice trade, including kapur barus (camphor). The ethnobotanical significance of kapur barus (Dryobalanops aromatica), a tree species native to Indonesia, has been recognized since ancient times by Arab and Chinese traders. However, the declining interest of younger generations in traditional plant-based knowledge threatens the preservation of this cultural heritage. Preliminary observations indicate that information regarding the ethnobotany of kapur barus in Barus District remains limited, and no specific study has been conducted in the area. This research aims to document ethnobotanical knowledge related to kapur barus among local communities in Barus District, Central Tapanuli Regency. The study employed a qualitative descriptive approach with field-based methods. Informants were selected purposively, consisting of eight community representatives. Data were collected through semi-structured interviews guided by a question list. The results reveal that kapur barus is utilized in various aspects of local life, including botany, ethnopharmacology, ethnoeconomics, ethnolinguistics, and ethnoecology. The species plays an important economic, medicinal, and cultural role for the people of Barus District. This study underscores the significance of preserving traditional ethnobotanical knowledge and highlights the potential for its sustainable development.
