Prasetyo, HamdaniDwi (2013) Penggunaan Diversitas Vegetasi Riparian Lokal untuk Peningkatan Kualitas Air Irigasi Tersier di Desa Kedung Pedaringan Kecamatan Kepanjen Kabupaten Malang. Sarjana thesis, Universitas Brawijaya.
Abstract
Air irigasi berperan penting dalam pengairan sawah. Air irigasi sering tercemari oleh limbah industri, limbah domestik, dan limbah pertanian. Vegetasi riparian diduga mampu mengurangi pencemaran air irigasi dengan menyerap bahan kimia dalam air dan mengkontrol beberapa parameter fisikokimia di saluran air irigasi. Oleh karena itu, dilakukan penelitian yang bertujuan: (1) mengetahui potensi Limnocharis flava, Ipomoea aquatica, Fimbristylis globulosa, Vetiveria zizanoides, Equisetum ramosissium, Typha angustifolia, Sesbania grandiflora dan Scirpus grossus dalam meningkatkan kualitas air irigasi, (2) Mengetahui pengaruh panjang dan lama waktu penanaman vegetasi riparian terhadap kemampuannya dalam meningkatkan kualitas air irigasi. Penelitian ini adalah eksperimen semu dengan melakukan penanaman vegetasi riparian sebagai agen fitoremediasi secara in situ di saluran irigasi penampung yang merupakan outlet dari masing-masing sawah. Pengukuran parameter fisikokimia meliputi temperatur, konduktivitas, TSS, TDS, pH, oksigen terlarut, nitrat, bikarbonat, ortofosfat, serta amonium dilakukan pada waktu 30, 40 dan 50 hari setelah penanaman vegetasi riparian. Hasil penelitian menunjukkan bahwa penanaman beberapa hidromakrofita lokal sebagai vegetasi riparian di saluran irigasi mampu meningkatkan beberapa parameter kualitas air. Pada penelitian ini, penanaman vegetasi riparian sepanjang 275 m selama 50 hari mampu meningkatkan kualitas air irigasi secara signifikan yang tercermin dari penurunan nilai beberapa parameter yaitu TDS, TOM, ortofosfat, ammonium dan nitrat serta meningkatkan kadar oksigen terlarut di perairan.
English Abstract
Irrigation water has an important role in irrigating rice fields. Irrigation water is often contaminated by sewage from industrial, domestic, and agricultural waste. Riparian vegetation is assumed to enable reduce pollutant by absorbing chemical compounds in the water and controls several physicochemical parameters of water in irrigation canal. Therefore, this research was carried out to: (1) determine the potency of Limnocharis flava, Ipomoea aquatica, Fimbristylis globulosa, Vetiveria zizanoides, Equisetum ramosissium, Typha angustifolia, Scirpus grossus, and Sesbania grandiflora for improving the quality of irrigation water, (2) determine the influnce of length and duration of planting riparian vegetation toward it’s abillity for improving the quality of irrigation water. This study is a quasi-experiment by planting riparian vegetation as phytoremediation agents in situ at irrigation canal as an outlet of rice fields.Measurement of physicochemical parameters research including temperature, conductivity, TSS, TDS, pH, dissolved oxygen, nitrate, bicarbonate, dissolved phosphate, and ammonium were measure at 30, 40 and 50 days after planting of riparian vegetation. Result showed that planting some local hydro-macrophytes as a riparian vegetation in irrigation canal able to improve some parameters of water quality. The planting of riparian vegetation along 275 m for 50 days can significantly able to improve water quality that can be seen from decreasing the value of some physicochemical parameters such as TDS, TOM, dissolved phosphate, ammonium, and nitrate as well as increasing the concentration of dissolved oxygen.
