Abstract

This study aims to assess the water quality of the Pesouha River and identify key pollution-contributing parameters using various types of analysis. The Pollution Index Analysis values range from 0.617 to 2.47, indicating quality from good to light pollution. Additionally, the Water Quality Index (WQI-INA) analysis results range from 79.2 (fairly good) to 90.93 (very good). Correlation analysis of Cr6+ and iron (Fe) in water is 0.91; TSS and (Cr6+) is 0.85; TSS and Fe is 0.86; TSS and IP is 0.68; Cr6+ and IP is 0.72; Fe and IP is 0.6. Regression analysis using hexavalent chromium (Cr6+) as the independent variable (X) and the Pollution Index as the dependent variable (Y) yielded a multiple R-value of 0.722, indicating a strong correlation between X and Y. The Adjusted R2 value is 0.46, meaning X can explain Y, in this case, the parameter (Cr6+) can explain Y or Pollution Indeks by 46%, and other factors influence the rest. The regression equation formed is Y = (-0.099) + (0.12) X, meaning that if the value of X = 0. then the value of Y is (-0.99) with a positive relationship between parameters.

Abstract

Rapid population growth in Bandar Lampung, especially in coastal areas, has impacted the environment. Pasaran Island is a small inhabited island that originally only had an area of 2 ha but has now grown to 12.02 ha due to sedimentation and reclamation carried out by the island's residents. Pasaran Island faces great challenges, especially related to carrying capacity and capacity to maintain environmental sustainability and the quality of life of its residents. This study aimed to analyze the carrying capacity and capacity of Pasaran Island. A spatial analysis approach was used to evaluate land requirements and the limits of the island's ability to support its population optimally. Spatial calculations used were according to the Regulation of the Minister of Public Works No.20/PRT/M/2007 on techniques for analyzing physical, environmental, economic, and socio-cultural aspects in preparing spatial plans. The results showed that the carrying capacity on the Pasaran Island is 0.601, which means that the carrying capacity of the settlement is low and unable to accommodate the population in the area. Based on the analysis of the carrying capacity of people, when viewed specifically on Pasaran Island, it can only accommodate 827 people, even though there are currently 1,500 residents. Thus, the results show that there is an overpopulation of 673 people.

Abstract

The availability of water and quality of clean water are increasingly affected by population growth. As the human population expand, the demand for goods and services rises, often leading to intensified in water use and pollution. This study examines the correlation between land cover changes and water quality in the Cisadane River Basin. Water quality data were collected as a time series from 2019 to 2022, focusing on eight parameters:  TDS, TSS, BOD5, COD, DO, TP, NO3-N, and NH3-N. Water quality classification was carried out using the Pollution Index (IP) method. Land cover changes were analyzed through visual interpretation using ArcGIS at a 1:10,000 scale. Multiple linear regression analysis was used to assess the influence of land cover on river water quality. The results indicate that the overall water quality in the Cisadane River Basin falls under the ‘slightly polluted’ category, with noticeable influence from land cover changes. Between 2019 and 2022, built-up land increased by approximately 5.5% contributing to elevated BOD₅ levels in several locations, such as Babakan and Genteng, indicating rising organic pollution from domestic waste and urban activities. Conversely, a decrease in vegetation cover by around 6.3% at various observation points correlated with decreased DO levels, especially in downstream areas such as Tanjung Burung and Vihara, potentially disrupting aquatic ecosystem balance. These findings suggests that vegetation cover plays an important role in maintaining water quality and ecological stability, while the expansion of built-up and agricultural areas tends to elevate pollutant loads in river water. Therefore, the results of this study can serve as a reference for policymakers in spatial planning of the Cisadane River Basin, especially in developing land conservation and waste management strategies to improve water quality and maintain the sustainability of water resources in the region

Abstract

This research aimed to analyze blue carbon potential and mangrove ecosystem management in promoting climate change mitigation in Indonesia. The collected data included mangrove area data obtained through the Indonesian National Ecosystem Monitoring System (SIMONTANA). This research calculated the carbon stock using the global average of mangrove carbon stock. The results showed that the total blue carbon stored in mangrove ecosystems reached 3,267.87 Megaton Carbon (MtC). Papua and Kalimantan regions contributed the most significant potential, with 1,707.22 MtC and 608.17 MtC, respectively. The absorption of carbon dioxide (CO2) reached 11,982.21 MtCO2e. The most significant CO2 gas emissions absorption was observed in the Papua region, amounting to 6,259.80 MtCO2e, followed by Sumatra with 2,118.59 MtCO2e. This high potential value correlated with mangrove ecosystem management policies, such as conservation, restoration, and blue carbon monetization. Mangrove management for climate change mitigation was carried out through national and international cooperation to achieve the 26% to 40% emission reduction target. The existing management model of mangrove ecosystems focused on improving ecological sustainability with less orientation on improving community welfare. Implementing blue carbon monetization at the district level by involving the community as the owners or managers of the mangrove ecosystems is crucial.

Abstract

The increased use of detergents during the COVID-19 pandemic has raised concerns regarding their impact on aquatic environments, particularly water quality and aquatic biota. Even prior to the pandemic, the effects of detergent exposure on water quality and aquatic organisms had been studied, but the surge in hand soap and cleaning product usage has likely led to higher concentrations of Linear Alkylbenzene Sulphonate (LAS), a common active ingredient. This study aimed to determine the median lethal concentration (LC50) of detergent compounds, observe behavioral changes in Oreochromis niloticus (Nile tilapia), and examine histopathological damage to gill tissues following exposure. The LC50 value was determined to be 0.061 mg/L, with an effective concentration range between 0.059 mg/L and 0.063 mg/L. Behavioral responses observed in exposed fish included disorientation, reduced responsiveness, and lethargic movements. Histological analysis revealed significant damage to the gill tissue in exposed specimens compared to the control group. These findings indicate that increased detergent concentrations in aquatic environments may pose a significant threat to fish health and overall ecosystem stability.

Abstract

The coastal waters of Eretan located in the north of Indramayu Regency are used as fishing grounds by local fishermen. The condition of water input, especially from the surrounding river waters, namely the Cimanuk River, Cipunagara River, and Perawan River, is thought to affect the condition of coastal waters. This study aims to analyze the trophic level based on water quality conditions. Data collection on the quality of the aquatic environment was carried out in three locations with purposive sampling considerations, namely the Cipunagara estuary, the Perawan estuary, and the Cimanuk estuary. Sampling was carried out in two different seasons, namely the dry season and the rainy season. The method used in the analysis is the TRIX Index based on nutrients, phosphate, chlorophyll-α, and DO saturation. Meanwhile, water quality parameters at each location were analyzed using principal component analysis (PCA). The results of the study showed that the main water quality parameters tended to differ in each season. The trophic level at the three locations had values between 4.99 and 8.59, so they had mesotrophic to hypertrophic status. This shows that coastal water conditions need to be managed so that water conditions are more stable.
