Abstract

The Estuaries of Progo and Opak rivers, being the terminus of all rivers flowing through the Special Region of Yogyakarta, are highly susceptible to pollution which results in decreased water quality. The use of meiofauna as a bioindicator to assess water quality in the estuaries of Progo and Opak rivers has never been made. This study aims to determine the diversity of meiofauna at the estuaries of Progo and Opak rivers. Stations and sampling points are determined using purposive sampling method. Extraction is conducted using water ice treatment method. The meiofauna obtained from the sediment screening are then identified, calculated and analyzed to find out the index values ​​of abundance, dominance, diversity, and evenness. The results showed that the highest meiofauna abundance index was 247,333 ind. m-2 at the estuary of Progo river station 1 at the time of the first pick-up. While the lowest meiofauna abundance was 13,333 ind. m-2 at station 2 of Opak river estuary during the first take. The dominance at the estuaries of Progo and Opak rivers is in the moderate category. The meiofauna diversity in both river estuaries is categorized as low to moderate. Evenness in both estuaries is uneven at several stations. The meiofauna diversity at the estuaries of Progo and Opak rivers is low to moderate, although the water quality still meets the quality standards.

Abstract

Sleman Regency has the most temple cultural heritage in Yogyakarta, supported by Green Open Space (GOS). The area is a habitat for urban birds and can be used as an indicator of environmental quality. This study aims to analyze the environmental quality based on the soundscape and character of the bird community in the GOS of Prambanan Temple and Ratu Boko Temple. Sound recordings were taken with a smartphone, and the recording time was set using the Arbimon touch in the morning, afternoon, and evening. The sound recordings are used to calculate acoustic indexes. The sound recordings and spectrograms are processed to identify bird species and calculate the Bird Community Index. The number of bird species was higher in the Ratu Boko area. According to the NDSI value, the sound of biophony at Ratu Boko Temple is more dominant than anthrophony and geophony. The environmental quality in the Prambanan Temple area is in the low category than in the Ratu Boko Temple area, which is classified as a medium category. The area's topography, the arrangement of vegetation, and the noise of vehicles due to the proximity to the highway affect the environment quality in temple areas.

Abstract

Productivity and quality of crops can be increased through polyploidy plants induced by antimitotic compounds such as vinka alkaloids.The use of vinka alkaloids has never been applied to Sword bean (Canavalia ensiformis), a tropical legume belonging to the Fabaceae family. This study aimed to determine the effects of vinka alkaloids treatment on the morphological characters of Sword bean. The treatment consist of four different vinka alkaloids concentrations (0.5%, 1.00%, 1.50%, 2.0%, and untreated (0.0%) act as control. The plants were arranged in a completely randomized design. Treated plants were characterized based on morphological traits such as plant height, leaf area and dry seed weight. The results obtained revealed significant difference (p≤0.05) in the morphological traits of the treated plants when compared with the control. Overall, 2.0% vinka alkaloids concentration resulted in higher average plant height by 193.8 ± 1.86, leaf area increments by 88.6 ± 5.1 (left leaf), 115.1 ± 4.7 (middle leaf), 86.2 ± 3.8 (right leaf) and the dry seed weight by 1.7 ± 3.6. The improvement of the traits is concentration dependent and increases with increment in vinka alkaloids concentration. Thus, we suggested that 2.0% concentration should be employed in improving Sword bean growth and yield.

Abstract

Rapid industrial growth may have implications for an increase in cases of pollution of soil ecosystems through untreated waste disposal. Copper and chromium are metals found in some types of industrial wastewater, such as electroplating and silversmithing, that are essential at low concentrations but toxic at high concentrations. Vigna radiata was chosen as the test organism because it has been reported that the yield and production of the crop have decreased worldwide due to heavy metal pollution. This study aims to evaluate individual and mixed Cu and Cr toxicity in the seed germination of V. radiata. The individual and mixed Cu and Cr toxicity test was started with a range-finding and definitive test for 96 h. The toxicity level of the individual metal was expressed as IC50-96 h by probit analysis. For the mixed test, the organism was exposed to concentration ratios of Cu and Cr: 10%:90%; 35%:65%; 50%:50%; 65%:35%; and 90%:10% of individual IC50-96 h, each conducted for 96 h. The results showed that the individual IC50-96 h of Cu was 127.4 mg/L, while for Cr, it was 615.23 mg/L, indicating that Cu is more toxic than Cr. The mixed test showed that the IC50-96 h of Cu was 247.5 mg/L, 579.85 mg/L for Cr. The highest inhibition value at the mixed test was at a Cu and Cr concentration ratio of 90%:10%. Based on the mixed test, the interaction of Cu and Cr resulted in an additive effect (CI=1).
