Abstract

Sampah masih menjadi permasalahan yang sangat kompleks. semakin meningkatnya jumlah penduduk berbanding lurus dengan semakin meningkatnya timbulan sampah selain itu sampah kerap menjadi masalah terutama di daerah-daerah yang mengalami pertumbuhan penduduk, sampah dituding sebagai biang keladi kerusakan lingkungan dan berbagai sumber penyakit. Kebanyakan berupa sampah plastik dan streofrom, padahal kedua jenis sampah ini sulit untuk terurai. Sehingga tujuan kegiatan Pengabdian kepada Masyarakat ini adalah untuk pemberdayaan masyarakat dalam mengolah sampah rumah tangga yang berkelanjutan sehingga tidak terbuang di TPA. Kegiatan Pengabdian kepada Masyarakat ini dilakukan di Balai Desa Soidodadi Kecamatan Ngantang dan di Lokasi TPA Desa siodadi. Hasil kegiatan pengabdian kepada masyakarat adalah masyarakat dapat membedakan sampah yang organic dan anorganik. Saran yang diharapkan dari kegiatan ini adalah masyarakat dapat menerapkan pengolahan sampah rumah tangga melalui 3R serta pembuatan kompos ini secara berkesinambungan dan hasil komposnya dapat dimanfaatkan kembali untuk pupuk tanaman.

Abstract

Duckweed, a widely used natural fish feed, has also become more popular as the phytoremediation agent for wastewater, including one sourced from aquaculture. These two features indicate that duckweed can be utilized in a sustainable aquaculture system by treating and reclaiming nutrients from wastewater and then harvesting them for fish feed production. Hence, this study attempted to assess the approach of the two most known duckweed species, i.e., Lemna minor and Spirodela polyrhiza, in depleting NH4 and PO4 from synthetic controlled aquaculture wastewater as well as to understand their yield based on the N : P ratio. Cultivation in synthetic aquaculture wastewater media was carried out, followed by nutrient uptake and growth analysis. According to statistical analysis, both L. minor and S. polyrhiza could remove NH4 and PO4 with a relatively equal rate (p-val > 0.050). Nonetheless, both duckweed species absorb nitrogen more easily than phosphorous (p-val < 0.050). Considering the yield based on nutrient uptake, NH4 drove a more efficient yield for L. minor to S. polyrhiza at 16.70 g dry biomass/g NH4 and 14.14 g dry biomass/g NH4, respectively. Meanwhile, a higher yield was observed on S. polyrhiza than on L. minor regarding PO4 concentration, at 19.31 g dry biomass/g PO4 and 9.10 g dry biomass/g PO4, respectively. Therefore, a strategy to remove nutrients and produce biomass for fish feed can be formulated based on the N : P concentration ratio, where L. minor tends to produce biomass more rapidly in a higher N : P ratio, whereas S. polyrhiza works in the opposite.
