Abstrak. Indonesia merupakan negara tropis dengan curah hujan yang tinggi menjadi faktor utama penyebab terjadinya kerusakan tanah. Kerusakan tanah menyebabkan berkurangnya kemampuan tanah untuk menyerap dan menahan air serta terjadi sedimentasi pada tempat-tempat penampungan air seperti waduk, sungai, danau, saluran irigasi dan areal pertanian. Salah satu metode yang dapat digunakan dalam mengendalikan erosi yaitu metode vegetatif dengan memanfaatkan tanaman titonia (Tithonia diversifolia), rumput vetiver (Vetiveria zizanioides) dan rumput brachiaria (Brachiaria humidicola). Penelitian ini bertujuan untuk mengetahui kemampuan tanaman titonia, rumput vetiver dan rumput brachiaria dalam mengendalikan erosi pada lahan yang berlereng. Penelitian ini dilakukan di Kebun Kurma Lembah Barbatee, Blang Bintang Aceh Besar dengan membudidayakan/ menumbuhkan tanaman titonia pada lahan berlereng menggunakan plot pengamatan erosi. Hasil penelitian menunjukkan bahwa rumput vetiver mampu mengendalikan erosi dalam waktu 1 bulan, disebabkan oleh jarak tanamnya yang rapat dan populasi tanamannya banyak. Sementara tanaman titonia dapat mengurangi jumlah tanah yang tererosi setelah tanaman berumur 2 bulan dilapangan.Utilization Of Tithonia diversifolia, Vetiveria zizanioides and Brachiaria humidicola as A Terrace Reinforcement Plant for Erosion Control in Lembah Barbatee’s Date Garden, Blang Bintang Aceh BesarAbstract. Indonesia is a tropical country of high rainfall. It is a major factoe in the deterioration of the soil. Soil damage causes the soil to be unable to absorb water, hold water, and can cause soil sedimentation in areas such as reservoirs, rivers, lakes, irrigation and agricultural areas. The vegetation method was one of the methods used to control erosion by tithonia (Tithonia diversifolia), vetiver grass (Vetiveria zizanioides) and brachiaria grass (Brachiaria humidicola). The main aim of this research to determine the ability of titonia to control the erosion on sloping land. This research was done in the Lembah Barbatee’s date garden, Blang Bintang Aceh Besar by planting tithonia, vetiver grass and brachiaria grass on sloping land and using the erosion plots. The result of this was that vetiver grass was able to control erosion in 1 month due to spacing of dense plants and it has a large population. Tithonia was able to control erosion after being planted for 2 months.

<p>Vetiver grass and it usages have been widely investigated in many researches as the preferred plant species due to its known efficiency, low cost, the ease of availability and spread. This research aimed to use four different vetiver grass (<em>Vetiveria zizanioides</em>) ecotypes to remove cyanide (CN<sup>-</sup>)-contaminated water for improve its quality. Growth capability, tolerance and removal efficiency were evaluated. The results showed that the vetiver grass had a 100% survival rate for one month after planting. Songkhlar3 had the longest leaves, followed by Surat-Thani, Sri Lanka and Monto, respectively. Root lengths of all ecotypes showed no significant differences (p ≤ 0.05). All vetiver grass ecotypes could potentially purify CN<sup>-</sup>-contaminated water at lower concentrations of ≤ 35 mg CN<sup>-</sup>/L. The Monto ecotype had the highest CN<sup>-</sup> removal efficiency at all CN<sup>-</sup> concentration levels, showing 100% CN<sup>-</sup> removal from the 5-45 mg CN<sup>-</sup>/L contaminated water samples within 2-5 weeks growth. The tolerance of vetiver grass to CN<sup>-</sup> was a more important factor than growth rate when selecting a vetiver grass ecotype for CN<sup>-</sup> phytoremediation.</p>
