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 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.

Abstract

ABSTRAK Hukum lingkungan di Indonesia telah mengalami berbagai transformasi selama empat dekade terakhir, terutama dalam bidang kebijakan dan peraturan Analisis Dampak Lingkungan (AMDAL). Namun, perubahan ini sering mencerminkan pergeseran yang meningkat ke arah kekakuan administrasi, yang mengorbankan tujuan substantif keberlanjutan dan kualitas layanan publik. Studi ini menerapkan Next Generation Framework (NGF), alat evaluatif komprehensif yang dikembangkan oleh Fonseca dan Gibson (2020) untuk melakukan meta-evaluasi terhadap lima peraturan lingkungan utama Indonesia yang dikeluarkan antara tahun 1986 dan 2021. Melalui analisis konten kualitatif dan penilaian berbasis ahli dari 50 elemen praktik baik di sepuluh kategori NGF, penelitian ini mengungkapkan kesenjangan kelembagaan kritis dalam rasionalitas hukum, integrasi keberlanjutan, mekanisme partisipatif, dan fleksibilitas adaptif. Temuan menunjukkan bahwa sementara peraturan terbaru menekankan perampingan prosedural dan integrasi digital, mereka secara bersamaan mengabaikan landasan normatif seperti keadilan lingkungan jangka panjang, hak-hak adat, dan tata kelola yang responsif. Penelitian ini menempatkan NGF dalam kerangka hukum normatif-praktis, memposisikannya sebagai alat diagnostik yang berharga untuk reformasi kelembagaan. Pada akhirnya, studi ini mengusulkan reorientasi desain hukum dalam tata kelola lingkungan yang menyelaraskan maksud normatif, praktik administrasi, dan responsif sosial-ekologis dalam pemberian layanan publik. Kata kunci: evaluasi hukum normatif; kelembagaan; environmental impact assessment; next generation framework; tata kelola lingkungan.   ABSTRACT Environmental law in Indonesia has undergone multiple transformations over the last four decades, particularly in the realm of Environmental Impact Assessment (EIA) policies and regulations. However, these changes often reflect an increasing shift toward administrative rigidity, compromising the substantive goals of sustainability and public service quality. This study applies the Next Generation Framework (NGF, a comprehensive evaluative tool developed by Fonseca and Gibson (2020) to conduct a meta-evaluation of five key Indonesian environmental regulations issued between 1986 and 2021. Through qualitative content analysis and expert-based scoring of 50 good practice elements across ten NGF categories, this study reveals critical institutional gaps in legal rationality, sustainability integration, participatory mechanisms, and adaptive flexibility. Findings show that while recent regulations emphasize procedural streamlining and digital integration, they simultaneously neglect normative foundations such as long-term environmental justice, indigenous rights, and responsive governance. The research situates NGF within a normative-practical legal framework, positioning it as a valuable diagnostic tool for institutional reform. Ultimately, the study proposes a reorientation of legal design in environmental governance one that harmonizes normative intent, administrative practice, and socio-ecological responsiveness in public service delivery.

Abstract

River hydrological factors are thought to influence the level of solid waste pollution that occurs in the Ciliwung River, this is one of the problems that causes a decline in river water quality and threatens the health of the surrounding environment. This research aims to analyze the influence of hydrological factors on the condition of solid waste pollution in the river. The research was conducted in April-June and August-November 2021 at five monitoring locations spread across Bandung Regency, West Bandung Regency, Purwakarta Regency and Bekasi Regency. The analysis used is a linear regression with the river width (X1), water level (X2) and current speed (X3) on solid waste reporting (Y). The analytical equation model obtained from this is Y = 0.0394 – 0.0041 X1 with a coefficient of determination value of 9,33% with a correlation coefficient reaching 30.55%. This research proves that narrow river width can increase the distribution of solid waste. Although hydrological factors influence forest ecosystems, a stronger influence is thought to come from human behavior factors that throw rubbish directly into rivers.

Abstract

Changes in plankton community structure can be an indicator of environmental changes due to oil pollution.. Oil pollution occurs along the coast of the Tambling Wildlife Nature Conservation (TWNC) area. This research aims to determine the plankton structure community including: abundance, diversity index, evennes index and dominance index in the TWNC area. There are 4 classes of phytoplankton in aquatic areas, namely Cyanophyceae, Chlorophyceae, Bacillariophyceae, and Dinophyceae. There are 7 classes of zooplankton in waters, namely: Protozoa, Rotifera, Crustacea, Nematoda, Polychaeta, Gastropoda and Diptera. Phytoplankton ranged 708,694 – 14,295,651 cells/m3, diversity index 0.38 – 1.64 (medium), evennes index 0.14 – 0.75 (medium to high) and a dominance index 0.29 – 0.88. Zooplankton abundance ranged 6000 – 142,609 cells/m3, diversity index 0.9 – 1.77 (medium), evenness index 0.5 – 0.91 (medium to high) and dominance index 0.19 – 0.58. The presence of plankton in the TWNC area is not influenced by oil waste contamination because at the time of the research no exposure to oil waste was found..

Abstract

Jakarta Bay is an active area and receives pollution from the mainland through 13 river systems in DKI Jakarta. This waste enters Jakarta Bay through 13 rivers. This study compared the distribution of dissolved heavy metals in the West and East Monsoons of Jakarta Bay to understand the processes and sources of heavy metals. Sampling was carried out once in each zone, and sea water samples stored in HDPE (high-density polyethylene) bottles were taken to the laboratory for analysis using AAS (Atomic Absorption Spectrophotometry), with a measurement accuracy of 0.001 mg/L. GIS was used to map heavy metal parameters. The concentrations of heavy metals found were mercury (Hg) 0.0002 to 0.0005 mg/L, copper (Cu) 0.0062 to 0.0089 mg/L, lead (Pb) 0.006 to 0.007 mg/L, zinc (Zn) 0.0247 to 0.0334 mg/L, and nickel (Ni) 0.0044 to 0.0088 mg/L. In summary, the study shows that the physical-chemical conditions of Jakarta Bay significantly affect the distribution of dissolved heavy metals such as Hg, Cu, Pb, Zn and Ni.

Abstract

Wood industry produces a large amount of waste water that contains various pollutants. These pollutants are mostly dangerous for the environment. This research work aims to analyze the ability of phytoremediation for reducing pollutants in wood industrial waste water. These experiments usee Chrysopongon zizanoides L. and Ipomoea aquatica Forsk as phytoremediation agents. The ability was evaluated from the improved quality of wood industrial wastewater and the growth rate of C. zizanioides (L.) and I. aquatica Forsk in wood industrial wastewater. Analysis was conducted by measuring the removal efficiency of pollutants in wood industrial wastewater, the correlation between the reduced pollutants concentrations in the waste water and plant growth rate. Furthermore, a mathematical model is developed to predict the potential of C. zizanioides (L.) and I. aquatica Forsk for wood industrial wastewater. The result showed that C.zizanioides L. and I aquatica Forsk were potential phytoremediation agent. The removal efficiency for C.zizanioides L. and I aquatica Forsk are respectively as follows: 66.19% and 41.18%, TSS 58.51% and 45.38%, COD 70.07% and 40.37%, Total Amonia Nitrogen (TAN) 63.70% and 66.96%, NH3 96.16% and 88.79%, and PO43- 53.90% and 38.38%. Relative Growth Rate (RGR) of C. zizanioides (0.011±0.002 g/day) is better than I. aquatica Forsk (0.007±0.001 g/day). Daily Growth Rate (DGR) of C. zizanioides (0.019±0.003 cm/day) is better than I. aquatica Forsk (0.012±0.006 cm/day). TSS, COD, NH3, NO3-, and phenol have a negative correlation to plant growth (based on wet weight and root length). The developed mathematical models can be used to predict the phytoremediation potential of C. zizanioides (L.) and I. aquatica Forsk in degrading COD, TSS, and phenols of wood industrial waste.

Abstract

Coastal waters of Bojonegara in Banten Bay has a lot of pressure from the surrounding environment, including industry and sand mining. The high intensity and limited space encourage reclamation in coastal areas which can trigger changes in water quality. Research was conducted from October to December 2019, aims to analyze the phytoplankton biodiversity and pollution bioindicator of the waters. The phytoplankton was obtained through filtering 50 liters of water at a depth of 30 cm or surface waters. Observations were also made on water quality conditions including transparency, depth, color, temperature, pH, salinity, and dissolved oxygen (in-situ) and turbidity, Total Suspended Solid (TSS), nitrate, nitrite, and total phosphate (ex-situ). Data analysis was performed on abundance, diversity index, eveness and dominance, similarity index, and saprobic index. Based on observations, it is known that the phytoplankton found were in the class Bacillariophyceae, Chlorophyceae, Cyanophyceae, Dinophyceae, and Chrysophyceae. The index values of diversity, eveness, and dominance of phytoplankton each ranged from 0.2223-1.0070; 0,1289-0,5664; and 0.1550-0.8181, respectively. According to these values, the Bojonegara waters were classifeied as mild to moderate ecological pressure. The similar conditions are also indicated by the saprobic index values. The result of Main Component Analysis (PCA) shows the first component with 53.726% variance represented by turbidity parameters, TSS, total phosphate, transparency, depth, temperature, pH, and DO. These parameters have the most influence on the presence of phytoplankton.
