Abstract

Cabbage is a widely consumed vegetable in Indonesia, but the role of soil macroarthropods in cabbage cultivation is often overlooked by farmers. This study aimed to analyze the structure of soil macroarthropod communities and the abiotic factors influencing them in monoculture and polyculture cabbage fields. The research was conducted in Batur Village, Getasan, Central Java, on three types of land: cabbage monoculture, cabbage polyculture, and forest as a control. Samples were collected using the pitfall trap method and identified at the Ecology and Biosystematics Laboratory. The highest diversity index was found in polyculture fields (H′ = 1.02), followed by monoculture (H′ = 0.85) and forest (H′ = 0.19). The evenness index was also highest in polyculture fields (E = 0.69). The Formicidae family dominated all three land types, with a community similarity index of 44% between monoculture and polyculture fields. Statistical tests showed significant differences between the forest and agricultural lands (p < 0.05), but no significant difference between monoculture and polyculture systems (p > 0.05). Correlation analysis revealed that soil moisture had a strong positive correlation with diversity and evenness, while temperature showed a negative correlation with those indices. These findings indicate that although polyculture tends to support higher diversity, the difference was not statistically significant. This information is expected to encourage more adaptive and sustainable farming practices while maintaining biodiversity in agricultural lands.

Abstract

Due to the surge in global food demand, aquaculture in Indonesia has expanded rapidly. Fish farming activities using floating net cages that neglect environmental pollution have become a significant issue in Lake Rawapening. Macrobenthic mollusks serve as valuable bioindicators for assessing disturbances in aquatic ecosystems, as they exhibit sedentary behavior, slow movement, and high sensitivity to fluctuations in water quality. This study aims to assess the structure of macrobenthic mollusk communities, environmental quality, and ecological status in the aquaculture areas of Lake Rawapening. Sediment samples were collected from polyculture, monoculture, and reference sites. A total of 9 species from 2 classes and 7 families were found at all three sites, with a low diversity index (H'), indicating limited community stability. Diversity was higher at polyculture sites compared to monoculture sites. Abiotic analysis showed that environmental parameters (temperature, pH, organic carbon, total nitrogen, phosphate) still met quality standards, although dissolved oxygen (DO) levels were low. The sediment substrate was dominated by clayey silt. Temperature was the abiotic factor most strongly correlated with mollusk abundance (r = 0.612; BIO-ENV, PRIMER 6.1.5). Based on the EWS-3 SWJ software, polyculture and monoculture sites were classified as moderately disturbed, while the reference area showed light to moderate disturbance.

Abstract

Insect diversity in agricultural ecosystems is influenced by cropping patterns and physical environmental conditions. In cabbage cultivation, it is crucial to understand cropping management to support the sustainability of agricultural ecosystems. This study aims to examine the effects of cropping patterns and environmental factors on insect diversity and evaluate the effectiveness of sticky traps in cabbage fields. Monoculture and polyculture systems (a combination of cabbage and lettuce) were tested to assess differences in insect community structure based on diversity, abundance, evenness, similarity, and dominance. The study was conducted from July to August 2019 using sticky traps in yellow, green, and white colors. The analysis included the Shannon-Wiener diversity index (H'), evenness (e), dominance (D), species richness, and Sorensen and t-Hutcheson tests. Environmental factors such as temperature and humidity were also analyzed to assess their impact on insect community structure. The results showed no significant differences in insect community structure between monoculture and polyculture systems, with the Aleyrodidae family dominating both systems. Temperature and humidity significantly influenced the insect community. Yellow sticky traps were found to be the most effective in capturing insects compared to green and white traps.
