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.

2025-04-30T14:56:05+07:00

Climate finance plays a critical role in addressing climate change issues. Global donors have provided substantial funding to support developing countries cope with climate change. However, due to the limited technical capabilities and high political interference risks in developing countries, donors face difficulties in disbursing their funds. Therefore, the government should set up a national intermediary to bridge the needs and expectations of the donors and local-level project beneficiaries. This intermediary will help mobilize more finance toward local-level projects pertaining to the attainment of the climate agenda. This study employs a qualitative method with a scoping review approach to analyze the most fundamental challanges faced by global donors in deploying their climate funds to developing countries. In addition, this study proposes alternative solutions for government to accelerate the mobilization of such funds. The government of Indonesia (GoI) has established a national intermediary called the Indonesian Environmental Fund (IEF) which operates under the Ministry of Finance. However, the IEF still faces various obstacles in carrying out its role. Further improvement will help enhance IEF’s capacity in fundraising, promoting blended finance and stenghthening project implementation capabilities at the local level.

2025-04-30T14:57:37+07:00

Drinking water in chicken farms is often contaminated with microbes that can cause several diseases in chickens. E. coli is a microbial pathogen treated with antibiotics and chlorine-based disinfectants, but it can leave residues in chicken tissues and cause resistance, threatening animal, human, and environmental health. So, it needs other alternatives, such as the use of antimicrobial zeolit filters that are made from natural materials and do not leave harmful residues. This study aims to determine the quality of chicken drinking water after applying antimicrobial zeolit filters and analyze the strategy for implementing filters in chicken farms. The study was conducted at Antoni Layer Farm, Sukabumi, West Java, from January to July 2022. Data was collected through experimentation, observation, interview, and literature study. Microbial data were analyzed using the BAM method and compared to PerMenKes (2017) and SNI (2009). Strategy analysis was conducted using SWOT analysis. The results showed that antimicrobial zeolit filters effectively reduced the number of Escherichia coli and Salmonella in chicken drinking water without leaving residues that are harmful to health and the environment and have the potential to develop. In conclusion, antimicrobial zeolit filters on poultry farms contribute to sustainable development goals by improve water quality on layer farms.

Data analysis included the Shannon-Wiener diversity index and gap analysis between physical and chemical water parameter data and water quality criteria according to PP RI Number 22 of 2021 (Class I). The results found that Toobaun springs consisted of 18 types of riparian trees, 14 types of Nekbaun springs. Meanwhile, in Merbaun springs there were 7 types, with a diversity index ranging from very poor to moderate. Furthermore, water quality parameters that did not fulfill the water quality criteria include BOD, COD and Pb.

Sintesis komposit berbasis styrofoam dan kulit kayu galam sebagai adsorben besi pada limbah cair pertambangan intan

2025-04-30T14:58:13+07:00

South Kalimantan Province is well known for its abundant diamond production. However, diamond mining activities leave excavation pits filled with water that cannot be utilized due to high concentrations of heavy metals. This study aims to develop an effective method for synthesizing a composite from styrofoam-derived polystyrene and cellulose extracted from galam wood (Melaleuca cajuputi) bark as an adsorbent, characterize the obtained composite, and evaluate its adsorption capability compared to commercially activated carbon for diamond mining wastewater treatment. Cellulose was isolated from galam wood bark, while polystyrene was obtained from styrofoam. The isolated materials were then used for composite synthesis. The adsorption process was examined by analyzing the effects of contact time and adsorbent mass. The optimal masses for the composite, activated carbon, and galam wood bark powder were found to be 1 g, 7.5 g, and 5 g, respectively. After treatment, the final turbidity levels using these adsorbents were 1.82, 486, and 232 NTU, respectively, compared to an initial turbidity of 1110 NTU. Atomic Absorption Spectroscopy (AAS) results indicated that the PSS-cellulose composite reduced iron (Fe) concentration from 38.30 mg/L to 24.12 mg/L.

Coral reef and seagrass ecosystem health assessment in Tiaro (LMMA), West Guadalcanal, Solomon Islands

2025-04-30T14:54:22+07:00

Coral reefs, seagrass meadows and associated fish communities are essential coastal ecosystems that provide significant ecological and economic benefits. However, these habitats are increasingly threatened by anthropogenic activities and climate change. This study assessed coral cover, reef fish composition and abundance and seagrass distribution in the Tiaro Locally Managed Marine Area (LMMA), Solomon Islands, to evaluate ecosystem health and conservation effectiveness. Ecological surveys at eleven sites revealed variable coral cover, ranging from 26% to 52%, with bleaching and disease most prevalent at Kotatave (11%) and Kokomu (10%). Herbivorous fish, particularly Pomacentridae and Acanthuridae, dominated the fish assemblages, while predatory species were scarce, suggesting trophic imbalance. Seagrass coverage varied across sites, with Cymodocea rotundata being the most dominant species, especially at Leleona (72% coverage). The findings highlight the interdependence of coral, seagrass and fish communities and emphasize the need for integrated, community-based conservation strategies to enhance ecosystem resilience.

“Clean smoke”: solusi inovatif dan efektif untuk mengurangi emisi gas karbon dan partikulat berbahaya pada asap

2025-04-30T14:58:55+07:00

Many environmental problems currently faced globally are related to air pollution, primarly originating from biomass combustion on both small or large scales. Major contributors to particulate matter (PM2.5) and harmful organic substances such as CO can be found in the smoke from the combustion process. These particulates and toxic substances have been known to have adverse effects on human health. This study presents the design and development of a device called Clean Smoke, which has an efficiency rate of 78.65% in reducing harmful substances in air emissions and effectively trapping organic compounds from biomass. In addition, the test results showed that the residual waste liquid or liquid smoke produced by this tool showed a significant turbidity increase from 4.16 NTU to 25.5 NTU, indicating the ability of the tool and activated carbon to bind hazardous particulates in water. With further development, Clean Smoke device could significantly reduce exposure to emissions and toxic substances from combustion processes in small to large-scale industries, thereby contributing to a healthier environment and supporting the global goal of achieving zero-net emissions.

This study aims to determine the types, abundance and composition of the stranded marine debris and its impact on the mangrove ecosystem in Liquiça Municipality, Timor-Leste. Data were collected from 6 September 2024 to 30 October 2024 at three stations using surveys and direct field observations. Analysis was conducted both quantitatively and qualitatively. Seven types of debris were identified : plastic, metal, glass, rubber, fabric, organic and other inorganic waste. Plastic was the most dominant at all stations, Station 1 recorded the highest debris abundance at 1.62 items/m², with plastic waste also dominating by category at Stations 1 and 3 (155 items/m² and 137 items/m²). Station 1 also had the heaviest debris weight at 4,339 g/m² and the largest volume at 235 cm³/m². The findings indicate that stranded marine debris does have a negative impact on the mangrove ecosystem, significant negative correlation between the weight of marine debris and macrozoobenthos. However no correlation between debris and mangrove’s seedlings was found.
