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 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.

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.
