Abstract

Butterflies (Lepidoptera) are essential pollinators and bioindicators of environmental quality. The Forest Area for Special Purposes (KHDTK) of UIN KHAS Jember has experienced forest conversion into agricultural and vegetable cultivation areas, raising the need for biodiversity data to inform management strategies. This study examined butterfly diversity and their host plants through field surveys using an exploration method. A total of 546 individuals representing 31 species from five families were recorded, with Nymphalidae as the most abundant family and Eurema hecabe and Ypthima pandocus as dominant species. The diversity index indicated a moderate level (H’=2.45), accompanied by low evenness (E=0.37) and high dominance (D=0.87). In addition, 20 host plant species from 12 families were identified, with Asteraceae and Verbenaceae being the most prominent. The findings reveal that despite habitat fragmentation, KHDTK UIN KHAS Jember functions as an important butterfly habitat, underscoring the urgency of conservation efforts through host plant enrichment and sustainable vegetation management to preserve pollinator community stability.

Abstract

The southern coastal ecosystem of Jember plays an important ecological role but is vulnerable to environmental pressures resulting from natural and anthropogenic activities. This study aimed to inventory mangrove and plankton communities and to analyze their relationships with water quality parameters as coastal bioindicators. Sampling was conducted using a purposive approach at six observation stations. Mangrove data were collected using transect methods, while plankton samples were obtained using a plankton net. Water quality parameters analyzed included temperature, pH, salinity, DO, and BOD, with relationships among variables assessed using Principal Component Analysis (PCA). The results showed that mangrove vegetation consisted of eight species belonging to four families, with Acanthaceae as the dominant family, while the plankton community was dominated by phytoplankton from the class Bacillariophyceae. PCA results indicated that Stations 3 and 6 were influenced by BOD, whereas mangrove and plankton distributions were more strongly correlated with salinity, pH, and DO. These findings demonstrate that the integration of mangrove and plankton communities is effective as a bioindicator of coastal water quality and provides a scientific basis for sustainable coastal ecosystem management.
