Abstrak. Penelitian ini bertujuan untuk mengetahui pengaruh sirkulasi air kolam budidaya ikan dan jenis media tanam non tanah terhadap pertumbuhan tanaman pakcoy (Brassica chinensis L.) dan bagaimana pengaruh interaksi keduanya. Penelitian dilaksanakan pada bulan Juni hingga Oktober 2020 di Gampong Pineung, Kecamatan Syiah Kuala Banda Aceh. Rancangan penelitian yang digunakan adalah Rancangan Acak Kelompok pola faktorial 4 x 2 dengan 3 ulangan. Faktor yang diteliti yaitu sirkulasi air kolam budidaya ikan yang terdiri dari 2 taraf (tanpa sirkulasi air kolam budidaya ikan dan menggunakan sirkulasi air kolam budidaya ikan) dan jenis media tanam non tanah (limbah serutan kayu, limbah sabut kelapa, biochar batok kelapa dan biochar cangkang kopi). Analisis data menggunakan Anova dan dilanjutkan dengan uji beda nyata terkecil (BNT) pada taraf 0,05%. Hasil penelitian menunjukkan bahwa sirkulasi air kolam budidaya ikan berpengaruh tidak nyata terhadap semua parameter yang diamati. Hasil penelitian juga menunjukkan bahwa media tanam non tanah berpengaruh sangat nyata terhadap tinggi tanaman, jumlah daun dan berat kering tanaman pakcoy umur 32 HST. Pertumbuhan tanaman pakcoy lebih baik dijumpai pada media tanam non tanah limbah sabut kelapa. Terdapat interaksi yang tidak nyata antara sirkulasi air kolam budidaya ikan dan media tanam non tanah terhadap pertumbuhan tanaman pakcoy.Effect of Water Circulation in Fish Cultivation Ponds and Non-Soil Planting Media on Growth of Pakcoy (Brassica chinensis L.)Abstract. This study aims to determine the effect of circulating water in aquaculture ponds and types of non-soil growing media on the growth of pakcoy (Brassica chinensis L.) and how the interaction between the two influences. The research was carried out from June to October 2020 in Pineung Village, Syiah Kuala District, Banda Aceh. The research design used was a 4 x 2 factorial randomized block design with 3 replications. The factors studied were the circulation of water in fish farming ponds which consisted of 2 levels (without circulating water in fish farming ponds and using circulating water in fish culture ponds) and types of non-soil growing media (wood shavings waste, coconut husk waste, coconut shell biochar and coffee shell biochar). Data analysis using ANOVA and continued with a test of least significance different (LSD) at 0.05% level. The results showed that the circulation of the fish culture pond water had no significant effect on all the observed parameters. The results also showed that non-soil growing media had a very significant effect on plant height, number of leaves and plant dry weight for pakcoy plants aged 32 DAP. Pakcoy plant growth is better found in non-soil planting media of coconut husk waste. The best concentration of pakcoy plant nutrients was found in coconut shell biochar non-soil planting media. There was an insignificant interaction between circulating water in fish farming ponds and non-soil growing media on the growth of pakcoy plants.
