Abstract

Riparian vegetation has a very important ecological role i.e. maintaining water quality, as a supplier of litter, as a habitat, and as a natural filter for various pollutants. Riparian vegetation is found along the side of the river, such as along the Talau, Belu river. The purpose of this study was to determine the composition and diversity of riparian vegetation. The research area consisted of three riparian types, namely teak plantations (A Station), mixed forest (B Station), and processed land (C Station). The method used was the quadrant method. Determination of sample size was based on the species-area curve. Data were calculated using the Shanon-Wiener diversity index. The research results revealed that at A station there were 29 species consisting of 24 families; at B station there were 53 species consisting of 31 families, and at C station there were 25 species consisting of 21 families. The highest diversity (H') was found at station B with a good diversity category, followed by A station with medium and low categories, and C station with a low category.

Abstract

Riparian trees play an essential role in maintaining the quality of the springs. This research was conducted to determine riparian tree types and water quality in Niukbaun Springs, Kupang district. Tree samples were measured by using the Quadrat Sampling Technique. Meanwhile, water quality measurement included physical, chemical, and microbiological parameters. All data collected were analyzed to determine the Shannon-Wiener diversity index, tree endemism status, and gap analysis (conformance of water quality profiles with water quality standards). The results revealed that there were 11 families consisting of Anacardiaceae, Arecaceae, Bombacaceae, Dendrocnide, Elaeocarpaceae, Euphorbiaceae, Meliaceae, Moraceae, Oxalidaceae, Sapindaceae, and Verbenaceae with a total of 149 individuals. The endemism status of the 15 tree species found was 80% classified as endemic and 20% classified as exotic. From the results of the physical and chemical quality tests of water, it was found that almost all parameters met the water quality standards, except for nickel (dissolved metal), which did not meet the water quality standards. Microbiological test results revealed a type of bacteria with similar characteristics to the bacteria Proteus mirabilis, Klebsiella aerogenes, and E. coli. Human activities impact the diversity of riparian trees and the quality of water in Niukbaun Springs.

Abstract

Springs are water resources for human. One of the components that maintain the springs is the riparian tree. The study aims to identify the diversity of riparian tree species and water quality in Teunbaun (Sonaf) spring, Kupang district. Measurement of tree samples used the Quadrant Sampling Technique, while water quality measurements included physical, chemical, and microbiological (MPN) parameters. Collected tree and water quality data were analyzed to determine endemism status, species richness index (Dmg), Shannon-Wiener diversity index (H’), and gap analysis (conformity of water quality profile with water quality standards). The results showed that 16 species of riparian trees from 12 families were found. The species that are often found are from the Arecaceae family. The value of Dmg and H’ were classified as moderate. The results of the physical and chemical quality tests of water revealed that almost all parameters achieved the quality standards, except for COD, cadmium and nickel. Futhermore, the MPN value found did not achieve the quality standar..

Abstract

Unconserved springs tend to be polluted by various organic wastes. Accumulation of organic waste causes water to be contaminated with coliform bacteria, thus reducing water quality. Biofilter technology can be applied to reduce the number of coliform bacteria. This study aimed to determine the ability of BioFilter K4Ser-Col (moringa seeds, rice husks and kesambi charcoal) to reduce total coliform in spring water. The research location was at the Riumata Spring, Nekbaun village, West Amarasi sub-district, Kupang district. The work consisted of preparing the BioFilter K4Ser-Col media, taking water samples, and testing MPN coliform. MPN coliform testing was done twice before and after the water filtration on the BioFilter K4Ser-Col media. The study's results showed a decrease in the MPN value before and after filtering. The MPN coliform value before filtering was 1600 MPN/100 mL. After filtered water on the BioFilter K4Ser-Col media, it decreased to 23.23 MPN/100 mL. This value had met the national water quality standards for the class I category based on PP No. 22 of 2021. Thus, the use of BioFilter K4Ser-Col media could greatly reduce the number of coliform bacteria in water.

Abstract

Edelweis (Anaphalis longifolia) is one of Indonesia's mountain vegetation that grows at an altitude of 1,000–2,000 meters above sea level and plays a role as a pioneer plant in volcanic soils. Anaphalis longifolia is one of the places in Kelimutu National Park, which spans altitudes of 1,000–1,731 meters above sea level. Using Landsat satellite imagery, the research aims to identify environmental factors influencing edelweis distribution. Data collection was conducted across six tracking routes: Moni, Wologai-Protelindo, Dedumudi, Niowula, Ratebeke, and Saga-Bukit Sokoria, combining field observations with the analysis of Landsat 8 imagery, elevation SHP, rock type SHP, and NDVI values. The results of the study show that the distribution of edelweis is most commonly found at an altitude of 1471-1599 meters above sea level. Meanwhile, the distribution of edelweis is at least at an altitude of 1114-1200 meters above sea level. The types of rocks in the Kelimutu National Park area are young volcanic rocks and the distribution of edelweis tends to be more abundant in areas with moderate NDVI values (0.25-0.35). Environmental factors such as temperature, humidity, sunlight intensity, soil pH, and wind speed play a role in the spread of Edelweis in Kelimutu National Park.

Abstract

The use of medicinal plants by indigenous communities represents a form of traditional knowledge that serves as a primary alternative for healthcare, especially in areas with limited access to formal medical services. In the Mount Inerie region, Ngada Regency, traditional healing practices are still preserved through the utilization of various local plant species. This study aims to describe the types of medicinal plants used by communities in five villages in Jerebuu District Ngada, Regency as well as to explore the methods of preparation and the cultural values associated with their use. A descriptive method with an ethnobotanical approach was employed, involving semi-structured interviews with 107 respondents, direct observations, and literature studies. The results revealed 33 species of plants used for traditional medicine, with parts such as leaves, rhizomes, fruits, and bark being utilized. Preparation methods include boiling, burning, pounding, or combining with traditional rituals. Knowledge about medicinal plants is passed down orally and remains a primary reference for the community in addressing various health issues. These findings underscore the importance of preserving local knowledge as part of biodiversity conservation and the development of health systems rooted in local wisdom.
