Abstract

Abstrak Sungai Kampar berasal dari Sumatra Barat dan bermuara di Teluk Meranti, Kabupaten Pelalawan, melewati permukiman masyarakat. Air sungai dimanfaatkan untuk kebutuhan domestik, penangkapan ikan, serta kegiatan budidaya ikan dalam keramba jaring apung. Perkembangan sektor industri pertanian dan perkebunan, serta kegiatan penambangan pasir dan kerikil (sirtu) yang berada di daerah aliran Sungai (DAS) Kampar pada umumnya belum memenuhi kriteria keberlanjutan lingkungan. Kondisi ini menimbulkan ketidakseimbangan antara upaya pemanfaatan dan upaya pelestarian di DAS Kampar yang kemudian memicu permasalahan ekosistem lingkungan. Tujuan penelitian ini adalah menghitung daya tampung beban pencemaran dan kapasitas asimilasi (AC) BOD, Fecal Coliform, dan Metilen Biru Aktif Substansi (MBAS) pada lokasi Pemantauan Kualitas Air (WQM) di Desa Danau Bingkuang, Sungai Kampar. Metode survei dilakukan dengan mengumpulkan data dari populasi representatif (sampel). Hasil perhitungan menunjukkan bahwa beban pencemaran terukur (PL) untuk BOD, Fecal Coliform, dan MBAS berada di bawah nilai maksimum daya tampung beban pencemaran (MPLC) untuk parameter BOD, Fecal Coliform, dan MBAS. Kapasitas asimilasi (AC) pada titik pemantauan TPP-12 Desa Danau Bingkuang tahun 2020 adalah: BOD sebesar 1,54 Kg/hari, Fecal Coliform sebesar 1,06 Kg/hari, dan MBAS sebesar 0,03 Kg/hari.   Abstract The Kampar River originates in West Sumatra and flows into Teluk Meranti, Pelalawan Regency, passing through community settlements. The water is utilized for domestic purposes, fishing, and fish farming activities in floating cage systems. The development of the agricultural and plantation industry sectors, as well as sand and gravel (sirtu) mining located in the Kampar watershed, has generally not met environmental sustainability criteria and has resulted in an imbalance between utilization efforts and conservation efforts in the Kampar watershed, causing environmental ecosystem problems. The purpose of this study was to calculate the pollution load capacity and assimilation capacity (AC) of BOD, Fecal Coliform, and Methylene Blue Active Substances (MBAS) at the Water Quality Monitoring (WQM) location in Danau Bingkuang Village, Kampar River. The survey method was conducted by collecting data from a representative population (sample). The calculation results showed that the measured pollution load (PL) for BOD, Fecal Coliform, and MBAS was below the maximum pollution load capacity (MPLC) for BOD, Fecal Coliform, and MBAS. The AC at monitoring point TPP-12 Danau Bingkuang Village in 2020 was: BOD = 1.54 Kg/day, Fecal Coliform = 1.06 Kg/day, and MBAS = 0.03 Kg/day

Abstract

This study aims to analyze the effect of QASE-based case study learning on students’ critical thinking skills in addressing peatland fire problems. This study employed a quantitative approach using a pre-experimental one-group pretest–posttest design to examine the effectiveness of QASE-based case study learning in improving students’ critical thinking skills. The sample was selected using purposive sampling, involving students enrolled in environmental science and disaster mitigation courses, as well as first-year students. A total of 105 students from the University of Riau participated in this study. Data were collected using Higher-Order Thinking Skills (HOTS) test instruments and observation sheets. The data were analyzed statistically using N-Gain analysis and a t-test. The results showed an improvement in students’ critical thinking scores, with the mean pretest score increasing from 69.74 to a mean posttest score of 87.28. The overall N-Gain score for students’ critical thinking skills was 0.57, which was categorized as moderate. Among the critical thinking indicators, the ability to synthesize showed the most significant improvement in classes A and B. Furthermore, the t-test results showed a significance value of p < 0.05, indicating that QASE-based case study learning was effective in improving students’ critical thinking skills in environmental learning. These findings suggest that the QASE model can be implemented as an alternative case-based learning strategy to enhance students’ Higher-Order Thinking Skills (HOTS), particularly in addressing environmental issues such as peatland fires.

Abstract

Giant gourami (Osphronemus gouramy) is one of Indonesia's most valuable freshwater fish species; however, its aquaculture development is constrained by slow growth and low survival rates. Improving water quality through the use of aquatic plants such as Lemna sp. and the application of eco-enzymes is essential. The development of Lemna sp. depends on nutrient availability, especially nitrogen (N), phosphate (P), and potassium (K), which can be enhanced by adding an eco-enzyme. This study aimed to evaluate the effect of different eco-enzyme concentrations on Lemna sp. biomass production, specific growth rate, and water quality parameters in giant gourami culture systems. The research was conducted using an experimental method with a Completely Randomized Design (CRD) consisting of five treatments and three replications: P0 (0 ml/L), P1 (1.5 ml/L), P2 (2.5 ml/L), P3 (3.5 ml/L), and P4 (4.5 ml/L) of eco-enzyme concentration. The results showed that eco-enzyme administration significantly influenced Lemna sp. biomass. The best results were observed in treatment P4 (4.5 ml/L), which produced the highest Lemna sp. biomass (132.87 g) and specific growth rate (4.47%). Optimal water quality was recorded in treatment P4, with temperature ranging from 26.1–29.8°C, pH 5.5–8.38, dissolved oxygen 3.10–6.42 mg/L, phosphate 0.3097–0.3872 mg/L, nitrate 0.5517–10.2414 mg/L, and CO₂ 17–40 mg/L. These findings demonstrate that eco-enzyme application at 4.5 mL/L effectively enhances Lemna sp. productivity as a natural biofilter while simultaneously improving giant gourami growth performance and survival

Abstract

Liquid organic fertilizer (LOF) derived from the solid waste of catfish processing is a fermented organic product containing macronutrients such as nitrogen (N), phosphorus (P), and potassium (K), as well as micronutrients, amino acids, and decomposer microorganisms that improve water quality. This study aims to analyze the effects of LOF application on peat water quality and the growth performance of climbing perch (Anabas testudineus), and to determine the optimal dosage for cultivation. The research was conducted from June to July 2025 at the Aquaculture Environmental Quality Laboratory, Faculty of Fisheries and Marine, Universitas Riau, with fish rearing carried out in the hatchery using aquarium. The study employed a Completely Randomized Design (CRD) consisting of five treatments: P0 (0 ml/L), P1 (1.5 ml/L), P2 (2 ml/L), P3 (2.5 ml/L), and P4 (3 ml/L), each with three replications. The results showed that water quality parameters remained within acceptable ranges, with temperature of 28.73–28.9°C, pH of 4.96–5.2, TDS of 108.26–124.6 ppm, transparency of 7.66–9.1 cm, DO of 5.23–5.36 mg/L, alkalinity of 17–28 mg/L, nitrate of 4.0045–8.7292 mg/L, and orthophosphate of 1.5397–3.5454 mg/L. The application of POC increased pH, TDS, nitrate, and orthophosphate concentrations. The best growth performance was observed in treatment P2 (2 ml/L), which produced the highest absolute weight gain (2.15 g) and absolute length growth (2.72 cm), while the survival rate reached 100% across all treatments. Therefore, the P2 dosage is considered the most effective treatment for improving peat water quality and enhancing the growth of climbing perch.

Abstract

Peatland waters hold great potential for aquaculture development; however, their unfavorable characteristics, such as low pH, brownish water color, and high levels of Total Dissolved Solids (TDS) and Total Suspended Solids (TSS), pose major challenges. One approach to improving peat water quality is the use of aquatic plants as phytoremediation agents, such as Lemna sp. This study aims to determine the effect of Lemna sp biomass on the physical parameters of peat water and to identify the optimal biomass for the rearing of Asian redtail catfish (Hemibagrus nemurus). The study was conducted from March to July 2025 at the Integrated Marine Science Laboratory of the Faculty of Fisheries and Marine Sciences at the Universitas Riau. The research method used was an experiment with a one-factor completely randomized design (CRD), consisting of five Lemna sp biomass treatments (0, 25, 37.5, 50, and 62.5 g/m²) and three replicates. The parameters observed included TDS, TSS, turbidity, temperature, pH, water color, absolute weight gain, and survival rate of Asian redtail catfish. The results showed that the addition of Lemna sp biomass significantly improved (P<0.05) the physical parameters of peat water. Increasing the Lemna sp biomass reduced TDS and TSS values and improved water clarity compared to the control without Lemna sp. These improvements in water quality positively affected the absolute weight gain and survival rate of Asian redtail catfish during the rearing period. A Lemna sp. biomass of 62.5 g/m² yielded the best results, with the most optimal physical quality of peat water and the highest growth and survival rates of Asian redtail catfish.

Abstract

Lemna sp. is an aquatic plant with high nutritional content, especially protein, and can grow rapidly in favorable environmental conditions. In addition to being a food source, Lemna sp. acts as a phytoremediator by absorbing ammonia, nitrate, and phosphate compounds derived from feed residues and fish metabolism. This study aims to investigate the use of Liquid Organic Fertilizer (LOF) derived from noni fruit to support the growth of Lemna sp. in tilapia fish culture media. The study was conducted from September to October 2025 at the Aquaculture Environmental Quality Laboratory, Faculty of Fisheries and Marine Sciences, Universitas Riau. This study used an experimental method. The experimental design used a Completely Randomized Design (CRD) consisting of 5 treatment levels and 3 replications so that there were a total of 15 treatment units, namely P0: Without giving noni fruit POC, P1: Giving noni fruit LOF 1.75 mL/L, P2: Giving noni fruit LOF 2 ml/L, P3: Giving noni fruit LOF 2.25 ml/L, P4: Giving noni fruit LOF 2.5 ml/L. The results of the study showed that the administration of noni fruit LOF at a dose of 2.5 ml/L was the best treatment for the growth of absolute weight in Lemna sp, with an average absolute weight of 145.66 ± 4.81 g and a specific growth rate of 4.70 ± 0.08% / day. Treatment with this dose was able to support the growth of tilapia for 30 days without commercial feed and only using Lemna sp as a single feed by producing an absolute weight of tilapia of 1.71 ± 0.10 g, an absolute length of 2.8 ± 0.11 cm, a specific growth rate of 3.22 ± 0.07 % / day, and a survival rate of 96%. In addition, the presence of Lemna sp in the maintenance medium acts as a phytoremediation agent, helping maintain stable water quality. Water quality parameters during the study remained within a reasonable range, with temperatures ranging from 26.4–30.1℃, pH 6.0–7.9, DO 4.1–7.2 mg/L, nitrate 0.06–19.05 mg/L, phosphate 0.13–4.16 mg/L, and ammonia 0.01–0.02 mg/L, supporting tilapia survival and growth.
