Abstract

Penelitian ini bertujuan untuk mengetahui potensi hidromakrofita lokal (M. vaginalis, L. hyssopifolia, dan L. adscendens) dalam mereduksi residu pupuk NPK. Penelitian dilakukan secara ex-situ di rumah kaca melalui fitoremediasi sistem batch culture. Media air irigasi yang digunakan sebanyak 30 L tiap bak dan ditambahkan tanah sawah 10 kg. Kemudian diberi pengayaan pupuk NPK sebanyak 50 mg.L-1. Pengukuran faktor fisiko-kimia dilakukan pada hari ke- 0, 1, 5, dan 10 meliputi nitrat, ammonium, dan fosfat terlarut. Perbedaan kualitas air antar perlakuan diketahui melalui analisis data menggunakan uji ANOVA atau uji Brown-Forsythe. Hasil penelitian menunjukkan bahwa hidromakrofita yang digunakan memiliki kemampuan yang sama dalam mereduksi residu pupuk NPK. Hidromakrofita mampu mereduksi lebih dari 95% konsentrasi nitrat pada hari ke-10 inkubasi, lebih dari 95% konsentrasi fosfat terlarut pada hari pertama inkubasi, dan lebih dari 80% konsentrasi ammonium pada hari ke-10 inkubasi.
