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.
