Abstract

Dragonfly is an indicator to environment and ecosystem in a particular area. It is also known as a balancing predator to another insects’ population. Various types of dragonfly are affected by some factors such as habitat conditions and the foods. Various types of dragonfly can be found in swamland, rice fields, flooded area, and also some locations around Universitas Tanjungpura. This research aims to convey information about various types of dragonfly in the area of universitas tanjungpura and also to define the index of variety of dragonfly types (H), equalization index (e), domination index (D), and species similarity (IS). This research took two weeks of fieldwork by applying purposive sampling, which was started from 5th – 15 th  April, 2018. Where the researcher is free to down each location seen from the large number of dragonflies are found. Then each location specified each plot with a distance of 15 meters each point of view of forming a circle pattern diameter 30 meters. The researcher found that 16 type of dragonfly consist of 13 type categorized as Subordo Anisptera and 3 type categorized as Subordo Zygoptera. The 13 Subordo Anisoptera consist of 12 types in libellulidae family and 1 type in Gomphidae family. The other 3 Subordo Zygoptera are in the the categoryof Coenagrionidae. This research shows that the role of dragonfly as a bioindicator and the predator of particular environment.

Abstract

AbstractFiddler crab (Uca spp.) is a unique type of small Uca crab that lives in a detritus-eating mangrove ecosystem. This kind of crab has a very important role, namely keystone species. Fiddler crab is included in the decapoda order, which is a group of Ocypodidae invertebrate families. The purpose of this study was to examine the diversity of fiddler crab species (Uca spp.). Based on habitat types and the benefits of research as a keystone species of mangrove ecosystem as a basis for efforts in preserving fiddler crab (Uca spp.). This research is a quantitative descriptive study with a survey and direct site-observation as the techniques of collecting data (Suprayogi et al., 2014). Line placement is done by purposive sampling which divided the area over three lines according to conditions of the field. Namely, line 1 was placed in front of the coastal area near the sea, line 2 was placed in the middle of which was overgrown with mangroves. Meanwhile, line 3 was placed behind the area that was more inland. The path length is 100 meters, which consists of 33 plots placed on the right and left side of the transect line with a distance between the plots of 2 m. The results of the study found 8 types of fiddler crabs, namely Uca paradussumieri, Uca dussumieri, Uca rosea, Uca forcipata, Uca crassipes, Uca tetragonon, Uca acuta and Uca annulipes with 333 individuals. Specifically, for fiddler crab of Uca annulipes type, there were 6 varieties based on the color and shape of the carapaceand the shape of the claws. The species diversity index  in the three research lines was classified as low because it ranged from 0,49 to 0,79. The physical-chemical factors of the environment in the three pathways were the pH of weak-alkali substrates ranging from 27-28 degrees Celsius, and low-salinity which was still in accordance with Uca’s life, that is 20.00 ppt. The soil texture consisted of three lines categories, line 1 which comprised lane 1.1 for clay-dusty land texture and lane 1.2 for clay-sandy texture. While line 2 was for dusty land texture, and lane 3 was for clay-dusty land texture. Keywords: Biodiversity, Fiddler Crab, Mangrove forest, Uca

Abstract

Orangutans (Pongo pygmaeus) are endemic to the island of Borneo whose existence is threatened with extinction. As a result of its population which has continued to decline over the past few decades, the International Union for Conservation Nature (IUCN) raised the status of Bornean orangutans from endangered to critical (Critically endangered). The study was conducted in the conservation forest area of PT. Kayung Agro Lestari (KAL) District Ketapang. This study aims to determine the diversity of species of feed for orangutans (Pongo pygmaeus Wurmbii) and to determine the availability of feed for orangutans in their original habitat. The method used is purposive sampling by making a double plot that is placed randomly at the location found in the type of orangutan feed. The results of this study found as many as 38 types of plants, 30 species are food sources and 8 species are not sources of feed. Analysis of the Important Value Index (INP) data of the largest value at all growth rates for tree level and seedlings was dominated by jungkang type (Palaquium leiocarpum) with a value of 33.83% and 54.01%. The level of the pole is dominated by the type of guava change (Syzygium sp1) with a value of 26.69%, while for the stake level is dominated by the type of pandanus (Pandanus sp) with a value of 47.67%.Keywords: Feed, Orangutan, Species diversity

Abstract

The diversity of ant species is one of the links in ecosystem stability as decomposing insects as well as food sources so that its existence becomes very ecologically important. Information about the types of ants found in the urban forest of Ketapang Regency is not yet available, therefore the problem of this research is how the diversity of ant species (Formicidae) in the urban forest of Ketapang Regency. This study aims to document the richness and diversity of ant species in the urban forest of Ketapang Regency, West Kalimantan. The method used was purposive sampling and systematic where the placement of traps was carried out according to the presence of ants in terrestrial and arboreal types in secondary forest habitats. Based on the results of research in the urban forest of Ketapang Regency, which was carried out in two types, namely terrestrial type and arboreal type, 10 species of 5 sub-families were found. Sub-families and types of ants found include: Dolichoderinae (Dolichoderus burmanicus, Dolichoderus taprobanae ceramensis), Formicinae (Aphomomyrmex afer, Polirachis browni, Prenolepis fisheri, Chepalotes femoral), Myrmicinae (Crematogester yameni, Crematogester indet), Ponerinae (Odontomachus haematodus), Pseudomyrmecinae (Tetraponera attenuata). The species diversity index (H') in terrestrial type secondary forest habitat (H'= 0.62) and arboreal type (H'= 0.81), the results of the two types in the secondary forest can be concluded that it is still relatively low.Keywords: Ants, Secondary forest habitat, Species diversity
