Abstract

Gulma merupakan salah satu tanaman yang dapat menghambat pertumbuhan, perkembangan, dan produktivitas dari tanaman sehingga manusia berupaya untuk mengendalikannya. Gulma dapat mengganggu manusia dengan beragam intensitas tertentu. Rumput teki (Cyperus rotundus L.) merupakan tanaman gulma perennial yang tumbuh di daerah tropis ataupun subtropis. Rumput teki dapat tumbuh secara liar di lahan kebun, pertanian, tanah lapang, dan tepi jalan. Umumnya para petani berupaya mengendalikan tanaman budidaya mereka dengan herbisida sintetik atau kimia, namun jika digunakan secara terus-menerus akan menimbulkan dampak yang buruk pada ekosistem sekitar. Maka dari itu, penelitian mengenai herbisida nabati yang lebih ramah lingkungan perlu dikaji guna mengetahui potensi dalam menghambat gulma pada area pertanian, perkebunan, maupun ladang. Penelitian ini menggunakan ekstrak daun bandotan (Ageratum conyzoides L.) yang dianggap liar namun memiliki kandungan yang berpotensi dimanfaatkan sebagai herbisida nabati. Kandungan senyawa golongan fenol disinyalir pula dapat berpotensi sebagai pengendali gulma sehingga berpotensi pula sebagai herbisida nabati. Parameter yang dilakukan yakni dengan pengukuran tinggi tanaman (TT), berat basah (BB), dan berat kering (BK) untuk mengetahui potensial dari ekstrak daun bandotan (Ageratum conyzoides L.) dalam menghambat gulma rumput teki (Cyperus rotundus L.). Hasil uji penelitian ini mendapatkan pengaruh yang nyata pada selisih tinggi dan berat basah tanaman rumput teki (C. rotundus) antara P0 (0%) dengan P1 (40%), P2 (60%), P3 (80%), serta P4 (100%). Sedangkan pada hasil berat kering tidak berbeda nyata antara semua perlakuan. Secara fisiologi rumput teki menunjukkan tidak berbeda nyata. Ekstrak daun bandotan (A. conyzoides) mampu mengendalikan pertumbuhan gulma rumput teki (C. rotundus). Hasil uji fitotoksisitas menunjukkan bahwa mulai dari konsentrasi 80% dan 100% terpengaruh pada kondisi bentuk dan warna daun tidak normal hingga mengalami kematian. Konsentrasi ekstrak yang berpotensi menghambat pertumbuhan rumput teki (C. rotundus) ditunjukkan pada P1 (40%), P2 (60%), P3 (80%), dan P4 (100%).

Weeds are one of the plants that can inhibit the growth, development, and productivity of crops so humans try to control them. Weeds can disturb humans with a variety of certain intensities. Teapot grass (Cyperus rotundus L.) is a perennial weed plant that grows in tropical or subtropical areas. It can grow wild in gardens, farms, fields, and roadsides. Generally, farmers try to control their cultivated plants with synthetic or chemical herbicides, but if used continuously, it will have a negative impact on the surrounding ecosystem. Therefore, research on plant-based herbicides that are more environmentally friendly needs to be studied to determine the potential in inhibiting weeds in agricultural areas, plantations, and fields. This study uses bandotan (Ageratum conyzoides L.) leaf extract, which is considered wild but has content that has the potential to be used as a vegetable herbicide. The content of phenol group compounds is also alleged to have the potential to control weeds so that it also has the potential as a vegetable herbicide. Parameters carried out are by measuring plant height (TT), wet weight (BB), and dry weight (BK) to determine the potential of bandotan leaf extract (Ageratum conyzoides L.) in inhibiting teki grass weeds (Cyperus rotundus L.). The results of this research test obtained a significant effect on the difference in height and wet weight of teak grass (C. rotundus) plants between P0 (0%) with P1 (40%), P2 (60%), P3 (80%), and P4 (100%). While the dry weight results were not significantly different between all treatments. Physiological teki grass showed no significant difference. Bandotan leaf extract (A. conyzoides) is able to control the growth of weed grass (C. rotundus). Phytotoxicity test results showed that starting from 80% and 100% concentrations affected the condition of abnormal leaf shape and colour until death. The concentration of extracts that have the potential to inhibit the growth of weed grass (C. rotundus) is shown in P1 (40%), P2 (60%), P3 (80%), and P4 (100%).
