Abstract

The Welang River in the Gunung Baung Nature Tourism Park (TWA), Pasuruan, plays a vital role as a source of clean water, irrigation, and ecotourism, but is vulnerable to contamination from upstream areas with dense activity. This water quality degradation requires monitoring, and biological analysis using plankton as a bioindicator is a holistic method due to the sensitivity of these organisms to environmental changes. This study aims to determine the structure and plankton community (phytoplankton and zooplankton) in the Welang River and analyze its ecological condition based on the plankton diversity index. The method used is descriptive quantitative with a purposive sampling technique at three stations. Sampling was conducted using a volume sampler technique and abundance was calculated using a Sedgewick Rafter Counting cell. Data analysis included calculations of abundance, Diversity Index (H'), Evenness (E), Richness (R), and Dominance (D). The results showed that the plankton community as a whole was in the category of moderate diversity, high evenness, and very low dominance. This value indicates that the Welang River waters are in a stable ecological condition and are not heavily polluted. As conclusion, the water quality of the Welang River is stable but shows an early warning of nutrient enrichment from anthropogenic activities, especially from the upstream.

Abstract

This research is a descriptive-quantitative study that evaluates the ecological condition of the Kehati Campus Forest at UIN Maulana Malik Ibrahim Malang through an integrated monitoring approach. The analysis includes estimating vegetation carbon stock, mapping tree distribution using geotagging methods, assessing groundwater infiltration potential, and identifying bird diversity as an ecosystem bioindicator. Vegetation data were collected by measuring tree diameter and height to calculate biomass and carbon storage, while geotagging was employed for spatial mapping of vegetation distribution. Groundwater infiltration potential was projected based on species dominance, whereas bird diversity was assessed using the line transect method. The results indicate that Artocarpus heterophyllus exhibited the highest dominance value and contributed substantially to carbon storage, with a total vegetation carbon stock of 2,341.78 kg. Geotagging successfully visualized stand distribution from seedling to mature tree stages, reflecting the dynamics of natural regeneration. The groundwater infiltration potential was also found to be relatively high, confirming the area’s role as a recharge zone. In addition, twelve bird species were recorded, with a Shannon-Wiener diversity index (H’ = 2.36), categorized as moderate. These findings underscore the strategic role of the Kehati Campus Forest as a conservation space, carbon sink, water regulator, and biodiversity habitat within the university environment.
