Abstract

Red spinach is widely cultivated and consumed by the public because it has high antioxidants, vitamins (A, C, E), protein, carbohydrates, fats, minerals, iron, magnesium, manganese, potassium and calcium. P giving POC can increasered spinach biomass. Nutrients in POC have been decomposed so that they are easily absorbed by plants. This study aims to analyze the giving of POC Lemna sp. on growth and biochemical content of red spinach and determine the concentration of POC Lemna sp. effective for red spinach (Amaranthus tricolor L.). The study used a completely randomized design with 3 replications and 3 treatments. The independent variable in this study was the concentration of liquid organic fertilizer Lemna sp. (A=0%, B=5%, and C=10%). Data were analyzed by ANOVA test and DMRT test at 5% level. The results showed that the administration of POC Lemna sp. gave significantly different results on the A (0%) treatment of plant height, stem diameter, and flavonoid parameters. Giving POC Lemna sp. can increase the growth and flavonoid content of red spinach. The concentration of liquid organic fertilizer Lemna sp. 5% effective for the growth of red spinach (Amaranthus tricolor L.).

Abstract

Spiders have an important role in ecosystems, in particular agricultural ecosystems. Spiders play the role of natural enemies capable of helping farmers by eating insect pests. The purpose of this study was to identify the type of Sub-Order Aranaemorphae and calculate the level of diversity and dominance of the type of Sub-Order Aranaemorphae in the generative phase of rice aged 90 days. The study was conducted in April-September 2022 in the rice field area of Tamanan Village. The determination of the research location was carried out using the purposive sampling method with the criteria of a rice field area of 2500 m2 and the age of rice plants ranging from 90 days. Sampling was carried out on 9 plots with a plot size of 21 x 4 m2 each. Sampling was carried out by hand picking and indirect methods with sweep nets, pitfall traps, and yellow pan traps. The species of Sub-Order Aranaemorphae found in this study were 12 species, namely Oxyopes sp., O. lineatipes, O. javanus, Atypena formosana, Tetragnatha vermiformis, Pardosa pseudoannulata, Lycosa sp., L. pseudoannulata, Lycosa sp. 1, Araneus inustus, Clubiona  sp.  and Thomisus  Sp. The conclusion of this study were the diversity index value (H') of the Aranaemorphae Sub-Order obtained in this study was 2.133 with a moderate category, and the dominance index value (D) of the Aranaemorphae Sub-Order obtained was 0.1785 with a low category. The total number of spider individuals obtained was 173 individuals.

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).

Abstract

Collembola has an important value for the environment as a bioindicator in maintaining the balance of the ecosystem. Land conversion in the UAD campus 4 area can reduce the diversity of Collembola. This study aims to find out the level of diversity of Collembola species that exist on campus 4 of UAD and its surroundings, and also find out which areas have the highest and lowest number of individuals. The research area for sampling in this study is the UAD 4 campus area, vacant land, housing and rice fields. Sampling was carried out as many as four repetitions. The collembola trapped in the pitfall trap is then moved in a microtube. The collembola that has been obtained is then identified up to the species level. The data obtained were analyzed by descriptive analysis. The types of collembola obtained at campus 4 UAD and its surroundings are Folsomia sp,, Isotoma sp., Isotomurus sp., Entomobrya sp., Sminthurus sp., Hypogatrusa sp, and Lepidocyrtus sp. The collembola species that is most commonly found are from Entomobrya famili with 106 individuals and the least individual from Sminthuridae famiili with 4 individuals.

Abstract

Jatimulyo is an ecotourism area consisting of several areas, each of which has a different height and abiotic factors. This can affect the morphometric character of frogs including Chalcorana chalconota. Research on specific morphometric variations of Chalcorana chalconota in Jatimulyo ecotourism has never been conducted. The purpose of this study was to analyze the distinguishing character of four frog populations as well as analyze the morphometric variation of the Chalcorana chalconota frog in Jatimulyo ecotourism. The research samples were taken using the visual encounter survey method and direct collection in the field in all four populations. Morphometric measurements use 32 characters. The measurement data obtained were analyzed using the Kruskall-Wallis test followed by UPGMA to see dissimilarity using the MVSP 3.1 program. The results showed that of the 32 characters observed and analyzed, there were nine characters that had a p<0.05 value which means it is significant to distinguish the four populations. The nine characters are (HW), (TD), (MFE), (MBE), (HAL), (LAL), (FOL), (IN), (MTL). LK, DT, JMMD, JMMB, JIN, PMD, PBR, PTJ4, PTM. The frog Chalcorana chalconota population of Kembang Soka has a high morphometric similarity with the population of Kedung Pedut. The Mudal River Population and the Bull Kedung Population have a considerable morphometric similarity with the Soka Flower and Pedut Flower Populations. This study can be concluded that the morphometric variation of Chalcorana chalconota in Jatimulyo ecotourism is influenced by altitude factors.
