Abstract

Organic matter entering through the inlet and activities in the Koto Panjang Reservoir body is feared to be the main source of nutrient contribution in the form of nitrogen (N) and phosphate (P) for reservoir waters. Nutrients N and P are utilised by phytoplankton in the photosynthesis process. If this condition continues, it is feared that it will affect water quality (blooming algae) which has an impact on aquatic biota. This study aims to determine the type and abundance of phytoplankton along with the distribution of chlorophyll a in reservoir waters. This study used descriptive, qualitative and quantitative methods and analysed the distribution of chlorophyll a using surfer software. Based on the results of the study, it is known that water quality is relatively good with temperatures ranging from 26-310C, brightness ranging from 0.69-1.96 m, dissolved oxygen (DO) is 5.60-6.80 mg/L and turbidity is 1-6 NTU. The results showed that phytoplankton composition was composed of 5 classes consisting of Euglenophyceae (1 species), Cyanophyceae (3 species), Conjugatophyceae or Zygnematophyceae (4 species), Chlorophyceae (4 species) and Bacillariophyceae (10 species). The dominating class in the reservoir zonation is different. In the riverine zone the Bacillariophyceae class dominates by 60.06%, in the transition zone the Cyanophyceae class by 91.60% and in the lacustrine zone the dominating class is Conjugatophyceae or Zygnematophyceae by 78.69%. Phytoplankton abundance ranged from 166.5-2,193 sell/m3. The highest abundance was located in the lacustrine zone and the lowest abundance in the riverine zone. The distribution of chlorophyll a in Koto Panjang Reservoir is varied, the highest distribution is located in the transition zone to the lacustrine zone.

Abstract

Waste pollution into the Citarum River (main water source of Jatiluhur Reservoir) was dominated by the manufacturing industry sector (textile, chemical, metal, pharmaceutical). Industrial was the most common contributor to heavy metal waste. Heavy metal contamination into waters will cause any problems, one of which was the emergence of various diseases both short and long term. Based on the issues, the study of heavy metal contamination and also water quality parameter conditions in the Jatiluhur Reservoir was necessary. The heavy metals (Cu, Zn, Hg, Pb, Cd) contents were determined using the X-Ray Fluorescence (XRF) Spectrometry method (for sediment) and Atomic Absorption Spectrometry (AAS) method (for water). The other water quality parameters were analyzed using the methods from the Indonesian National Standard (SNI). Furthermore, the data were compared to the Canadian Sediment Quality Guidelines (for heavy metal in sediment) and water quality standards from Government Regulation of the Republic of Indonesia Number 82 of 2001 (Class 3) (for water quality parameters). Concerning the discussion, Jatiluhur Reservoir was divided into three zones i.e. the inlet area, main inundation area, and outlet area. Conditions in the sedimentary layer, mercury (Hg) have accumulated throughout the Jatiluhur Reservoir area with conditions exceeding the maximum limit, while Cu metal tends to accumulate in the inlet area with conditions exceeding the minimum limit. For other heavy metals, exceed the minimum limit at some locations, but more results were below that. Although all heavy metals have not been detected in water, this was a warning that the presence of heavy metals in sediments can potentially dissolve into the water, the most extreme thing that can happen was upwelling. If this happens, the heavy metals can be contained excessively in water, harmful to and possibly consumed by aquatic biota and human. Considering these conditions, the biota that was most likely to be exposed was benthic organisms. In general, the water quality parameters in Jatiluhur Reservoir meet the quality standards. Only ammonia that does not meet the quality standards for sensitive fish life, regarding the massively of aquaculture activity in this reservoir.

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 study aims to analyze garbage waste data by day in a week at the Cituis Fish Landing Base (PPI Cituis), identify the causes of waste issues, and provide recommendations for waste management and handling. The research was conducted over two weeks of observation. Data were collected through waste characterization, total and average garbage waste volume measurements, the number of waste containers, and waste type composition from several source points. The results show that waste volume tends to increase at the end of the month, on weekends, and during holidays, following higher visitor numbers and fishing activities. Inorganic waste, especially plastic was the most dominant type across all port zones. The 3 kg container representing the harbor area had the highest percentage of waste bins compared with the 4 kg and 10 kg containers. Proper waste management is necessary to minimize pollution impacts at PPI Cituis and the surrounding environment. Recommended actions include improving waste facilities, strengthening governance and regulations, and enhancing community awareness and participation.

Abstract. Erlangga, Effendi H, Damar A, Taryono, Nurjaya IW. 2025. Phytoplankton diversity as a bioindicator of organic pollution in the estuary of Lhokseumawe City, Aceh, Indonesia. Biodiversitas 26: 3528-3544. Phytoplankton biodiversity serves as a crucial bioindicator of organic pollution in estuarine ecosystems. This study aims to assess phytoplankton diversity in the Lhokseumawe Estuary, Aceh Province, Indonesia, to evaluate organic pollution levels. Sampling was conducted at five stations from July to November 2024 using a purposive sampling method. Phytoplankton were identified and analyzed to determine species composition, abundance, and ecological indices. A total of 32 species from five major phytoplankton classes were identified, dominated by Bacillariophyceae (43%) and Mediophyceae, while Cyanophyceae contributed only 3%. The highest species richness was observed in July (25 taxa), decreasing to 20 taxa in September. Phytoplankton abundance declined from 20,525,346 cells/m³ in July to 13,609,643 cells/m³ in November. Spatially, the highest phytoplankton abundance occurred at stations 5 and 3, indicating localized nutrient inputs from surrounding anthropogenic sources. The Mediophyceae class exhibited the highest abundance, while Dinophyceae had the lowest. The Shannon diversity index (H’) ranged from 1.79 to 2.30 and evenness from 0.65 to 0.77, indicating moderate community stability with low dominance (0.14-0.24) across stations. The prevalence of Bacillariophyceae and Mediophyceae, particularly eutrophication-tolerant genera like Nitzschia, Navicula, Skeletonema, and Chaetoceros, suggests nutrient enrichment from anthropogenic sources such as domestic wastewater and agricultural runoff. However, the low Palmer Pollution Index score (6) and Algae Group Index value (3.61) indicate that organic pollution remains minimal, with diatom dominance reflecting relatively good water quality conditions. Seasonal variations in abundance and composition further highlight the influence of environmental changes and pollution on estuarine phytoplankton dynamics. These findings confirm that the Lhokseumawe Estuary is experiencing eutrophication driven by organic pollution, and the phytoplankton biodiversity metrics provide reliable indicators for monitoring such environmental disturbances. This study represents the first assessment of phytoplankton diversity in this region and provides essential baseline data for ongoing environmental monitoring and management strategies.

Abstract

Penelitian ini mengkaji apakah jumlah sambungan rumah tangga (SR) berkaitan dengan karakteristik air limbah domestik yang masuk ke instalasi pengolahan air limbah (IPAL) terdesentralisasi di Pulau Tidung Besar, Indonesia. Kumpulan data mencakup empat zona layanan (Utara, Barat, Timur, dan Selatan) yang diamati setiap tahun dari 2022 hingga 2025. SR diperlakukan sebagai variabel independen, sedangkan pH, BOD5, COD, TSS, minyak dan lemak, amonia, surfaktan anionik (MBAS), klorin bebas, koliform total, koliform feses, dan debit diperlakukan sebagai variabel dependen sesuai dengan ketersediaan data. Meskipun pemantauan dilakukan di inlet dan outlet IPL, studi ini hanya menggunakan data inlet untuk mewakili air limbah yang belum diolah yang masuk ke sistem dan untuk menghindari pengaruh proses pengolahan. Regresi linier sederhana eksploratori dan korelasi Pearson diterapkan pada pengamatan zona-tahun yang digabungkan, dilengkapi dengan validasi silang leave-one-out (LOOCV) sebagai pemeriksaan ketahanan prediksi. Jumlah sambungan rumah tangga meningkat dari 729 pada tahun 2022 menjadi 831 pada tahun 2025. Pada dataset gabungan 2022-2025, korelasi positif tertinggi di antara parameter utama teramati pada BOD5 (r = 0,362) dan COD (r = 0,346), sementara pH (r = 0,061), TSS (r = -0,135), minyak dan lemak (r = 0,216), serta amonia (r = -0,083) menunjukkan hubungan yang dapat diabaikan. Debit menunjukkan korelasi positif rendah dengan nilai yang lebih tinggi (r = 0,446) namun harus ditafsirkan dengan hati-hati karena kemungkinan adanya masalah pada pengukur aliran. Parameter yang diperkenalkan atau dihentikan setelah perubahan regulasi diperlakukan hanya sebagai eksplorasi. Tidak ada hubungan gabungan yang signifikan secara statistik (p > 0,05), dan LOOCV menghasilkan nilai R² prediksi negatif, yang menunjukkan stabilitas prediksi yang buruk. Secara keseluruhan, SR saja bukanlah prediktor yang andal untuk karakteristik air limbah yang masuk.
