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.

Abstract

Water is a fundamental human necessity that must be available in a safe and potable form. In religious heritage contexts such as the Sunan Ampel Mausoleum in Surabaya, drinking water is not only consumed but also revered as spiritually significant, often perceived as sacred. This dual perception raises the question of whether such water is both spiritually and scientifically “safe.” This study evaluated the quality of drinking water stored in traditional clay jars and stainless steel tanks, assessed against the Indonesian Ministry of Health Regulation No. 492/Menkes/Per/IV/2010. Three samples were analyzed for physical (temperature, TDS, pH), chemical (nitrite), and microbiological (Coliform and Escherichia coli, MPN method) parameters. The stateresults showed that while temperature was relatively high (≥30 °C), other physicochemical values remained within permissible limits [TDS: 135–186 mg/L; pH: 7.79–8.05; nitrite: 0.1 mg/L]. In contrast, all samples were microbiologically contaminated, exceeding the permissible limit of 0/100 mL. These findings demonstrate that, although the water meets physical and chemical standards, it poses a significant microbiological health risk. The study underscores the importance of sanitation monitoring and simple water treatment at religious sites, reinforcing the Islamic principle of halalan thayyiban (lawful and wholesome) consumption and highlighting the integration of scientific evidence with religious belief in safeguarding public health.
