Publisher : Universitas Ahmad Dahlan

One of the beneficial insects in agriculture and plantations is a predator. Using natural predators to control pests and diseases certainly has advantages. The purpose of this study was to calculate the level of predatory insect diversity in banana germplasm plantations and find the most abundant and least abundant predatory insects. The independent variable in this study is the banana germplasm plantation area, and the dependent variable in this study is the diversity and dominance of predatory insects found in the research location. Sampling in this study using a random method. The sweep net was in the morning, while the pitfall was collected, installed in the morning and taken in the afternoon. Predatory insect data analysis used in this study is to use the scan now-wiener diversity index and the Simpson dormancy index. The results showed that the predatory insects that mainly were found were the species, Paratrechina longicornis while the least that was found was the species Ischiodon scutellaris. From other results, namely the level of predatory insect diversity obtained, the results show that Yogyakarta banan germ plantation have moderate diversity of predatory insects. The conclusion of this study is that there is a disturbance in the Giwangan Banana Germplasm Garden Yogyakarta due to insects, so that the diversity index is moderate, while the predominance of predatory insects is 0.484, which means that in the ecosystem, one predatory insect is found that dominates.

Excessive alcohol consumption can lead to serious live injury. Alcohol is a source of free radicals that can cause oxidative stress. The provision of antioxidants can counter the effects of free radicals that enter the body. The skin of the Arabica coffee fruit contains antioxidant compounds that can be used as a hepatoprotective in the liver. The skin of the Arabica coffe fruit contains antioxidant compounds that may have a hepatoprotective effect on the liver. This study aimed to determine the effect of extract of arabica coffee fruit skin on necrosis, infiltration and haemorrhage in the liver tissue of 15% EtOH-induced mice for 15 days. The animals used for this study were eight weeks old male Balb/c strain mouse weighing approximately 30-40 grams. This research is an experimental study. There were five groups: the control group (K), the 15% ethanol treatment group (E), and the ethanol-induced group and given different doses of arabica coffee skin extract: 125 mg/kg BW. (A), 250 mg / kg BW (B) and 500 mg / kg BW (C). Observation and identification of necrosis, hepatocyte infiltration and haemorrhage were carried out by using Hematoxylin-eosin staining. The data analysis used was One way ANOVA and continued by Duncan Multiple Range Test (DMRT). The histopathological observations showed that the extract of arabica coffee fruit skin at a 250 mg/kg BW dose reduced the number of cell necrosis. There was no infiltration of inflammatory and hemorrhagic cells in the liver of 15% EtOH-induced mice. This study concludes that the extract of the skin of the Arabica coffee fruit has hepatoprotective potential in 15% EtOH-induced mice.

Antioxidant compounds can inhibit free radicals that are harmful to body health. The side effects of natural antioxidant compounds are safer than synthetic antioxidants. The source of natural antioxidant compounds can be obtained from jackfruit because it contains phenolics, flavonoids, sterols, and tannins. The study was conducted to determine the highest total phenolic content, total flavonoids, and antioxidant activity in the methanol extract samples of jackfruit from Sleman and Bantul Regencies. The extraction technique used maceration with methanol (1: 5) solvent. The phenolic content was tested by the Follin-Ciocalteu method at a wavelength of 745 nm, while the flavonoid content was tested using the AlCl3 method at a wavelength of 435 nm. The antioxidant activity was determined by the diphenylpicrylhydrazyl (DPPH) method at a wavelength of 517 nm. The results showed that the total phenolic and flavonoid content of the methanol extract of jackfruit from Bantul Regency was 1.927 m GAE / mg and 0.261 m QE / mg higher than Sleman Regency 1.353 m GAE / mg and 0.0913 m QE / mg and the highest antioxidant activity name in the sample extract from Bantul Regency, the IC50 value was 581.5 mg / mL and based on the results of statistical tests there were significant differences in content. This study concludes that the total phenolic content and total flavonoids as well as the antioxidant activity of the methanol extract of jackfruit from the Bantul Regency were higher than from Sleman Regency.

Prevalence and Intensity of Anchor Worm (Lernaea cyprinacea L.) Ectoparasite in Koi Fish (Cyprinus carpio L.) at Bantul Koi Farm D.I. Yogyakarta Wida Afriandini; Nurul Suwartiningsih

One obstacle in the cultivation of Koi fish (Cyprinus carpio L.) in Bantul Koi Farm D.I. Yogyakarta is a disease caused by parasites of anchor worms (Lernaea cyprinacea L.). Therefore, this study observed the prevalence and intensity of anchor worm ectoparasites in Koi fish in Bantul Koi Farm. Taking fish samples using the purposive sampling technique. Each of three fish individuals was taken as replication from three populations, namely Showa, Shiro and Saragoi, with a size of 28-36 cm. The prevalence and intensity are determined by the observation method by counting the number of anchor worms found. Inferential statistics carried out data analysis of the number of ectoparasites in each population. The results showed that the highest anchor tick ectoparasite prevalence was found in the Shiro population (100%) and the lowest in the Saragoi population (33%). The highest intensity was in the Showa population (4 individu/ fish), and the lowest was in the Shiro population (2 individu/ fish), although all of them were in a low category. The highest number of ectoparasites was obtained from the Showa population (8 individuals) and the lowest in the Saragoi population (3 individuals), but it was not statistically significant. The high prevalence in the Shiro population is due to the high stocking density. Anchor flea ectoparasites attacked the skin and fins of Koi fish and were not found to attack gills. The conclusion of this study is the highest prevalence of anchor tick ectoparasites was found in the Shiro population (100%) and the lowest in the Saragoi population (33%). The highest intensity was found in the Showa population (4 individu/ fish) and the lowest in the Shiro population (2 individu/ fish), even though all of them were in a low category.

The Covid-19 pandemic, which began in March 2020, resulted in enacting an online learning policy on campus. This study aimed to analyze the effect of online lecture policies on the composition of birds in the rice fields around Campus 4 of Universitas Ahmad Dahlan (UAD) Yogyakarta. Primary data collection was carried out at six points with the point count method in September 2020 and January 2021. Data analysis was carried out descriptivel by comparing observations with secondary data in September 2019 and January 2020, right before the Covid-19 pandemic. The results showed that the bird species present increased from 14 species to 32 species. The different paddy fields and rice morphology conditions in September and January also affect the bird species present. All birds present were not protected, and only one species, Acridotheres javanicus, was included in the IUCN Red List vulnerable category. Data collection on bird species must be carried out every year to monitor the presence of waterbirds in urban areas.

Publisher : Universitas Ahmad Dahlan

Botanical extracts have been reported as biopesticides, which act as antifeedants, insect growth regulators and repellents. As biopesticides, botanical extracts offer a more sustainable solution to pest control as chemical pesticides have a residual problem and are prone to pest resistance. The present study was conducted to evaluate the efficacy of waru leaves extract to control S. litura larvae in vitro conditions. The extract was prepared by maceration with methanol as a solvent. Third instar larvae of S. litura were randomly grouped into 6 treatments consisting of 0%, 3%, 6%, 9%, 12% and positive control (Lannate). Each treatment consisted of 3 replications. Leaf Dipping method was used in the treatment. Observations were made for up to 4 days. The parameters observed were changes in larval morphology, mortality, LC50 and LT50. Data were analyzed using One Way ANOVA (followed by LSD) and Probit analysis. The results showed that the highest activity of waru leaf extract was found at a concentration of 12%, which caused a mortality of 53% larvae. The LC50 value was at a concentration of 11.72%, and the LT50 value was 3.287. It can be concluded that the leaf extract has the potential to control S. litura larvae.
