Abstract

Soba Village, West Amarasi Subdistrict, Kupang Regency is located in East Nusa Tenggara Province with abundant natural resources. One of the natural resources is a natural spring with abundant diversity of riparian vegetation. The diversity of riparian vegetation around water sources plays an important role in water quality. This study aimed to identify the diversity of riparian vegetation around springs and to determine water quality. The method used was plot installation, identification of riparian vegetation types, measurement of environmental factors and water quality testing. The results showed that there were 12 species of tree vegetation with a total of 74 individuals, the most common tree species found was Canangan odorata with a relative abundance of 24.32%, followed by Cocos nucifera 18.92%, and Areca sp. 16.22%. Meanwhile, the least species found were Tectona grandis, Mangifera indica, Artocarpus altilis, and Syzygium aqueum with relative species abundance of 1.35%. The results of quantitative analysis of the relative frequency found tree species Areca sp. and Cocos nucifera had the highest value, namely 19.05%. Meanwhile, the highest relative dominance value was found in thespecies Artocarpus altilis. The results of water quality testing with 3 parameters namely physical, chemical and bacteriological showed a COD value of 85.03 mg / L, a total colifrorm of 45 and a total fecal colliform of 230

Abstract

The success of pea’s cultivation is influenced by the presence of arthropods that act as pollinators, decomposers, parasitoids and bioindicators. This research aimed at determining the diversity of arthropods on pea’s farming lands in Kupang district. This research was a descriptive quantitative research that had been carried out in three locations, namely peanut farming field, long bean farming field, and green bean farming field. Arthropod samples were taken by using pitfall traps, insect nets, and hand sorting. The results showed that arthropod diversity varied in the three pea’s farming lands. First, on peanut farming land, 31 species, 15 families, 9 orders, 2 classes were found, with a total of 115 individuals. Second, on the long bean farming land, 17 species, 11 families, 7 orders, 2 classes were found, with a total of 53 individuals. Last, there were 30 species, 20 families, 9 orders, 3 classes, with a total of 108 individuals found in green bean farming land. The highest diversity index was found in green bean farming land at 3.19, followed by peanut farming land at 2.83, and long bean farming land at 2.43. The highest species richness index value was found in peanut farming land at 6.32, followed by green bean farming land at 6.19, and the lowest in long bean farming land at 4.03. There was no arthropod species that dominated in the three peanut farming lands, the species were classified as evenly distributed. The similarity between Jaccard and peanut habitats showed a value less than 50%, meaning that the similarity level of the arthropod family found in the three pea habitats was low. The low level of similarity could be caused by the application of pesticides, especially in long beans and green beans farming lands. Furthermore, abiotic factors had a significant effect on arthropod diversity.

Abstract

Spring water quality is important for human health, so it needs to be preserved. The study aimed to identify spring water quality by approaching the data collection of tree species and insects that live in the spring area. The study was conducted in two springs in T and M villages, Kupang Tengah sub-district, Kupang regency. The study was descriptive, using a random systematic sampling method to obtain data on tree species, insect species, and spring water quality. Data on tree species and insects were analysed descriptively, while water quality data were compared with water quality standards according to Government Regulation No. 22 of 2021. The study found that 14 types of trees and 11 types of insects inhabited the springs. The water quality of the two villages met the physical parameter quality standards but not yet for chemistry and microbiology. Village T had not met the dissolved oxygen (DO) quality standards for categories I and II, while Village M had not met the biological oxygen demand (BOD) quality standards for category I. The water quality from the physical and chemical aspects was still suitable for community activities such as bathing, agriculture, fisheries, and animal husbandry. However, it must first be processed (cooked until boiling) for direct consumption.

Abstract

Springs are groundwater that comes out on its own to the surface of the earth. Water sources originating from springs are generally suitable for direct consumption because they undergo natural purification. However, the high demand for clean water causes springs to experience anthropogenic pressure, which can reduce the quality of spring water. The study aimed to determine the Bacteriological quality of spring water in Toobaun village. The method used in this study was the Most Probable Number (MPN), using a series of five tubes with a variety of 5-5-5. The test included three stages, namely the prediction test, the confirmation test, and the complete test. The data obtained were presented in the form of a table, then compared with the MPN table value and analyzed descriptively by comparing the MPN value with the water quality standard, namely PP No. 22 of 2021 (class I). The results of the study showed that the Fecal Coliform value found was 220 MPN/100ml and did not meet the quality standards of PP No. 22 of 2021 (Class I). In the complete test using EMBA media, three types of bacteria were found that had characteristics similar to Escherichia coli and Salmonella sp. Klebsiella sp. Based on the results of water testing at the Toobaun spring, it cannot be consumed directly without first being processed.
