Abstract

This study aims to: (1) find out the soil arthropod family found in red chili (Capsicum annum L.) cultivation with trap crop treatment of walnut plants (Tagetes erecta L.). (2) to determine the effect of trap crop treatment of walnut plants (Tagetes erecta L.) on red chili (Capsicum annum L.) cultivation on soil arthropod population dynamics. Data collection was carried out using the pitfall trap method. The population in this study is all soil arthropods found in red chili plantation areas, then the sample from this study is soil arthropods that are trapped in the pitfall trap. This research took place during August 2021-December 2021 with 5 data collections. The data taken included climatic and edapic data on each observation as well as all types of soil arthropods on red chili plantations. The data obtained were analyzed using descriptive analysis which included the diversity index, equality index, and dominance index. The results of the study showed that 17 families of soil arthropods were obtained. The population dynamics of soil arthropods in red chili cultivation have changed over time by showing ups and downs in yields. Habitat modification with trap crop of kenikir plants as a treatment did not have a significant effect on the population dynamics of soil arthropods in chili cultivation

Abstract

This research aims to identify the diversity of lichen species in three different areas: Temon, Kulon Progo; Depok, Sleman; and Tegalrejo, Magelang. Besides that to analyze their ecological role as environmental bioindicators. The method used was direct field observation with visual documentation using a mobile phone camera, followed by morphological identification. The results of the study successfully identified nine lichen species: Flavoparmelia caperata, Physcia atrostriata, Dirinaria applanata, Phlyctis argena, Acarospora socialis, Ropalospora viridis, Pyxine sorediata, Cryptothecia striata, and Graphis sp.. These species exhibited unique adaptations to various substrates (tree bark, rocks, and urban environments) and showed sensitivity to environmental changes, particularly air pollution. The mutualistic symbiosis between fungi and photobionts (algae/cyanobacteria) is key to the resilience of lichens in marginal habitats. These findings strengthen the potential of lichens as natural bioindicators and ecological pioneers, while also highlighting the need for further research to map the distribution and applications of lichens in Indonesia.
