Abstract

This study aims to explore the Species Richness Spiders (Arachnida) in the Kebun Wisata Pendidikan Universitas Negeri Semarang. Sampling was carried out by the roaming method, in June-July 2020 during the dry season. Spiders are collected using a pitfall trap (PFT) for spiders on the ground, and photographed for spiders that make their webs at a certain height. During sampling, the types of spiders were recorded, the number of individuals per species, the microhabitat of the spiders, with measurements of the abiotic conditions: temperature, humidity, light intensity. Data analyzed by using spider functional dendrogram and be collected regarding to the level of family, genus, and species. Quantitative data analysis includes analysis of Species Richness Index using the Margalef formulation. Species Diversity Index, using Shannon- Wiener. The results of the study concluded that: (1) there were 21 species of spiders caught on the ground, while others, 68 species, were found making nests in trees (2) The species richness of the spider in the UNNES KWP was moderate to high. Meanwhile, diversity index value of spider was high. (3) effort in species richness conservation of spider could be done in their natural habitat, also by adding various kinds of fruit plants to invite insects and spiders to come will effect on increasing species richness.
