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

The economic calculation of carbon emissions from a human activity is very helpful to analyze the emissions produced from waste generation and electrical energy consumption. The waste produced in activities at supermarket X has been sorted and separated from organic and non-organic waste. The electrical energy consumed by supermarket X is also large, but in the financing it is all paid by PT Y as the supermarket's shelter. The awareness of consumers and employees of the supermarket is also high regarding cleanliness and waste disposal.
