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

Lahan gambut memiliki peran penting sebagai penyimpan air, pengatur hidrologi, dan pendukung ekonomi masyarakat lokal. Kekeringan dan kebakaran lahan merupakan ancaman serius terhadap keberlanjutan ekosistem gambut. Pengabdian ini bertujuan untuk menganalisis peran edukasi dan pendampingan masyarakat dalam pengelolaan lahan gambut untuk menghadapi ancaman kekeringan. Metode yang digunakan adalah pendekatan pengabdian partisipatif, meliputi penyuluhan, pelatihan, dan pendampingan masyarakat dalam pemetaan dan pengelolaan lahan. Lokasi pengabdian dilakukan di Desa Rimbo Panjang Kecamatan Kampar yang dihadiri 15 orang. Hasil menunjukkan bahwa intervensi ini meningkatkan pemahaman masyarakat tentang pengaturan muka air gambut, praktik pertanian ramah lingkungan, dan strategi mitigasi kebakaran. Diskusi menekankan pentingnya integrasi edukasi, partisipasi masyarakat, dan pemberdayaan ekonomi untuk pengelolaan lahan gambut berkelanjutan. Hasil kuesioner menunjukkan skor rata-rata pengetahuan partisipan mengenai risiko kekeringan, pentingnya pengaturan muka air, dan praktik pertanian ramah gambut sebesar 58%, yang mencerminkan pemahaman masyarakat yang masih rendah dan belum optimal. Setelah dilakukan serangkaian edukasi interaktif, diskusi kelompok, dan workshop, skor rata-rata meningkat menjadi 85%. Kesimpulan dari pengabdian ini menegaskan bahwa program edukasi dan pendampingan efektif meningkatkan kapasitas adaptif komunitas terhadap ancaman kekeringan, dan berdampak pada penguatan konservasi ekosistem gambut oleh masyarakat.

Abstract

Measurement of Sedimentation Rate and Water Quality in Catfish Ponds Using Sediment Trap in Rumbai Bukit Subdistrict. Rumbai Bukit in Pekanbaru City, Riau Province, has aquaculture potential supported by the fish farming group mina usaha, which cultivates catfish (Pangasianodon hypophthalmus) in earthen ponds. The aim of this community service activity was to monitor the quality of catfish ponds using sediment traps, carried out in collaboration with Student Community Service from the University of Riau over a period of 40 days. This activity involved local fish farmers in Rumbai Bukit. Ten students provided assistance to improve pond productivity by monitoring pondquality through measurements of sedimentation rate, temperature, Total Dissolved Solids (TDS), and pH. Following the measurements, training was conducted and followed by continuous monitoring of water quality and fish growth. The analysis of water quality in relation to fish growth resulted in a graph showing the relationship between feed application and physical water parameters. The sedimentation rate in pond one was relatively high, averaging 71.85 ml/L, compared to 16 ml/L in pond two. The temperature in pond one ranged from 32°C to 35°C, while in pond two it ranged from 31°C to 34°C. TDS levels in pond one were relatively high, ranging from 112 to 194 ppm, compared to 9 to 24 ppm in pond two. The pH in pond one ranged from 6.9 to 7.5, while in pond two it ranged from 6.3 to 7.1. This community service activity was well received, with around 70% of fish farmers enthusiastically participating. The use of sediment traps was effective in monitoring sediment accumulation in catfish ponds. Ponds with poor management showed thicker sediment layers and a decline in water quality. Regular monitoring and efficient feed management are recommended to maintain optimal water quality and fish health. This activity has made a tangible contribution by increasing fish farmers' awareness and capacity regarding the importance of regular water quality monitoring, and by encouraging the adoption of more sustainable aquaculture practices to support local food security and the environmental sustainability of aquaculture in the Rumbai Bukit area.
