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

This research was aimed to study the role of riparian trees and ecosystem degradation to determine water quality in some springs and its channels located in East Java. The research was held in some selected degraded springs in Kediri, Pasuruan, Malang, and the Meru Betiri National Park located in Jember, as a reference site. In each spring, three sites including upstream, midstream, and downstream were observed. The field observation consisted of several steps such as land use quality at river land side, geographical conditions, riparian tree diversity and water quality, quality of springs physical condition, and its channels. Riparian trees role to determine the water quality was analyzed by applying Partial Least Square analysis with Smart PLS software. Structural modelling of the interaction of riparian trees diversity with some determining variables of water quality revealed that there was an important role of riparian diversity quality towards water quality. The value of predictive relevance (Q2) was 99.11% and the model could be accepted. The riparian trees diversity and geographical conditions directly influenced the water colour and its turbidity. The quality of land use at several water bodies did not directly influence the water colour and its turbidity. Therefore, water colour and its transparency at channels were directly influenced by riparian width, ecosystem degradation shown by naturalness index, hemeroby index, environmental services index, and the slope of landside.

Abstract

Insect diversity is believed to be used as a bio-indicator of spring quality, this study aimed at determining the spring insect diversity around the Mutis Timau Nature Reserve. The study was conducted from June to August 2019. Insects were caught by using the yellow pan trap and hand sorting. The diversity of spring insects was determined based on the Shannon-Wiener diversity index (H'), species richness index (R1), species dominance index (D), and evenness index (E). The results showed that 16 species belong to 11 families, and five orders of insects. The families included Gryllidae, Gryllotalpidae, Tetrigidae, Formicidae, Pompilidae, Apidae, Ochteridae, Veliidae, Hydrometridae, Nepidae, Coenagrionidae, Libellulidae, Carabidae, and Coccinellidae. The Shannon-Wiener species diversity index and the wealth index of the species of springs were classified as moderate (H '= 2.12 and R1 = 4.19). There was no type of spring insects dominated (D = 0.23). All springs insects were found to have almost the same level of evenness (E<1), with a value of 0.76. Abiotic factors such as pH and soil temperature were within the tolerance range of spring insects.

Abstract

This research aimed to determine the impact of degradation riparian tree diversity on water quality along some spring to its drains in East Java. This descriptive research conducted in selected springs and itsdrains in Jember, Kediri, Pasuruan, and Malang on April 2012 to January 2013. We used a spring water of Meru Betiri National Park as a reference site. Quality of riparian trees diversity and water were sampled with three replication.Data were tabulated by statistical analyzed using cluster and Spearman correlation. The result showed that species richness ofriparian tree in spring water and its drains has found were 69 species belonging to 28 families. Moraceae was key family of natural riparian tree and almost all the spring and its drains (92.75 %) were grown by native trees except in Kediri. All observed spring were degrading comparing to the natural one in Meru Betiri National Park where trees grown in strata A to E, and shown a highest diversity index (H=3.2). All water spring were observed in high quality but water in its downstream become turbid depend on the quality of treesriparian diversity grown around spring waters. Quality of riparian diversity was strongly influenced by land use and human activities such as illegal logging, intensive agriculture, and settlement. There was a positive correlation between riparian tree diversity, water transparency and color, but it had a negative correlation with pH value of water.Low pH, high water transparency and colorless water were found in stations where we found high tree species richness, diversity index, riparian width and stratified of tree.Keywords: Diversity quality, riparian tree, spring water , water quality.

Abstract

Community service was done as a concrete implementation of NTT Provincial Governor Regulation No. 56 2018. Following the adoption of the regulation, the team considered that it was necessary to promote the importance of English for the NTT community, especially for young children. As a Lingua Franca, English plays an important role; yet English language teaching is currently limited to lessons in class only without the assistance of its usage outside the classroom. The team believes it was a need to carry out a community service movement such as teaching that was more focused on the use of English language skills as early as possible. Introducing English to children from an early age was expected to improve the quality of the younger generation, especially in the language field. The method of implementing this community service was a teaching method by using children's songs and flashcards. The teaching was done face-to-face. The community service activities were run well and smoothly.
