Abstrak (Berisi Bastraknya saja, Judul dan Nama Tidak Boleh di Masukan)

Upaya peningkatan produktivitas tebu dilakukan melalui penerapan proses budidaya yang tepat. Proses budidaya tanaman tidak lepas dari berbagai kendala salah satunya ialah keberadaan gulma. Saat ini mulai berkembang jenis tumbuhan yang berubah menjadi gulma karena keberadaannya tidak diinginkan di perkebunan tebu yaitu tumbuhan keladi (Caladium bicolor) dan kunyit putih (Curcuma zedoaria). Kedua jenis tumbuhan tersebut berpotensi menjadi gulma serius karena sebarannya di beberapa petak kebun dan mulai mengganggu pertumbuhan tanaman tebu. Penelitian ini bertujuan untuk menguji efikasi herbisida triklopir, isopropilamina glifosat, dan campuran dalam mengendalikan gulma C. bicolor dan kunyit putih C. zedoaria pada budidaya tanaman tebu (Saccharum spp. hybrids), mengetahui pengaruh herbisida terhadap pertumbuhan tanaman tebu, dan menganalisis interaksi herbisida campuran (sinergis, antagonis, atau aditif). Penelitian dilakukan mulai September 2022 hingga Maret 2023 di PT. Gunung Madu Plantations dan Laboratorium Terpadu Universitas Lampung, menggunakan rancangan acak kelompok (RAK) di rumah kaca dan di lapangan. Pada Uji Rumah Kaca, 11 perlakuan diulang 6 kali yaitu kontrol ,herbisida bahan aktif triklopir 670 g ha , ipa glifosat 480 g ha -1 , triklopir 1.340 g ha -1 , triklopir 2.010 g ha -1 -1 + ipa glifosat 480 g ha , ipa glifosat 960 g ha -1 , Ipa glifosat 1.440 g ha -1 , triklopir 670 g ha -1 , triklopir 2.010 g ha -1 , triklopir 670 g ha -1 + ipa glifosat 960 g ha -1 -1 . sedangkan Uji Lapangan menggunakan 6 perlakuan dengan 4 ulangan yaitu kontrol, herbisida bahan aktif triklopir 670 g ha + ipa glifosat 480 g ha -1 , triklopir 2.010 g ha -1 + ipa glifosat 960 g ha -1 , triklopir 670 g ha -1 + ipa glifosat 480 g ha -1 + ipa glifosat 480 g ha -1 + ipa glifosat 960 g ha -1 , triklopir 1.340 g ha -1 -1 , dan penyiangan manual. Parameter yang diamati meliputi tinggi tajuk gulma, bobot kering gulma, dan pertumbuhan tanaman tebu. Data yang diperoleh dianalisis dengan analisis ragam yang sebelumnya telah diuji homogenites ragamnya dengan uji Bartlett dan , triklopir 1.340 g ha -1 + ipa glifosat 960 g ha -1 aditivitasnya dengan uji Tukey. Data diolah menggunakan metode analisis ragam dan teknik pemisahan nilai tengah diuji dengan menggunakan uji BNT pada taraf 5%. Analisis sifat campuran herbisida triklopir dan isopropilamina glifosat dilakukan dengan pengujian MSM (Multiplicative Survival Model) karena dua campuran herbisida yang diuji memiliki mekanisme kerja berbeda. Hasil penelitian menunjukkan bahwa herbisida triklopir efektif menghambat pertumbuhan gulma dengan dosis 670 g ha⁻¹ hingga 2.010 g ha di rumah kaca dan herbisida campuran triklopir dan isopropilamina glifosat dengan dosis 670 g ha⁻¹ + 480 g ha⁻¹ hingga 1.340 g ha⁻¹ + 960 g ha⁻¹ efektif menghambat pertumbuhan C. bicolor dan C. zedoaria tanpa mengganggu pertumbuhan tanaman tebu. Namun, herbisida campuran triklopir dan isopropilamina glifosat dosis 1.340 g ha⁻¹ + 960 g ha⁻¹ menyebabkan keracunan ringan hingga sedang pada tanaman tebu. Interaksi herbisida menunjukkan hubungan sinergis. Penelitian ini merekomendasikan penggunaan herbisida campuran dilakukan pada kebun yang memiliki sebaran dan dominansi gulma C. bicolor dan kunyit putih C. zedoaria yang tinggi, penelitian lanjutan diperlukan untuk mengoptimalkan efektivitas dan meminimalkan dampak toksisitas pada tanaman tebu. -1 Kata kunci: herbisida, Triklopir, Isopropilamina Glifosat, Caladium bicolor, Curcuma zedoaria, tebu Efforts to increase sugarcane productivity are carried out through the implementation of the right cultivation process. The process of cultivating plants is inseparable from various obstacles, one of which is the presence of weeds. Currently, there are types of plants that have turned into weeds because their presence is not desired in sugarcane plantations, namely taro plants (Caladium bicolor) and white turmeric (Curcuma zedoaria). Both types of plants have the potential to become serious weeds because they are spread across several garden plots and are starting to interfere with the growth of sugarcane plants. This study aims to test the efficacy of triclopyr, isopropylamine glyphosate, and a mixture of herbicides in controlling C. bicolor and C. zedoaria in sugarcane (Saccharum spp. hybrids) cultivation, determine the effect of herbicides on sugarcane growth, and analyze the interaction of mixed herbicides (synergistic, antagonistic, or additive). The study was conducted from September 2022 to March 2023 at PT. Gunung Madu Plantations and the Integrated Laboratory of the University of Lampung, using a randomized block design (RBD) in the greenhouse and in the field. In the Greenhouse Test, 11 treatments were repeated 6 times, namely control, herbicide active ingredient triclopyr 670 g ha , ipa glyphosate 480 g ha -1 , triclopyr 1,340 g ha -1 , triclopyr 2,010 g ha -1 , triclopyr 670 g ha -1 , ipa glyphosate 960 g ha -1 , ipa glyphosate 1.440 g ha -1 + ipa glyphosate 960 g ha -1 + ipa glyphosate 480 g ha -1 , triclopyr 670 g ha -1 , triclopyr 2,010 g ha -1 , triclopyr 2,010 g ha -1 + ipa glyphosate 480 g ha -1 -1 . While the Field Test used 6 treatments with 4 replications, namely control, herbicide active ingredient triclopyr 670 g ha + ipa glyphosate 960 g ha -1 + ipa glyphosate 480 g ha -1 , triclopyr 1,340 g ha -1 , triclopyr 670 g ha -1 + ipa glyphosate 960 g ha -1 + ipa glyphosate 960 g ha -1 + ipa glyphosate 480 g ha -1 , triclopyr 1,340 g ha -1 , and manual weeding. The parameters observed included weed canopy height, weed dry weight, and sugarcane growth. The data obtained -1were analyzed by analysis of variance which had previously been tested for homogeneity of variance with the Bartlett test and additivity with the Tukey test. The data were processed using the analysis of variance method and the separation technique for the mean value was tested using the LSD test at the 5% level. Analysis of the properties of the mixture of triclopyr and isopropylamine glyphosate herbicides was carried out using the MSM (Multiplicative Survival Model) test because the two herbicide mixtures tested had different working mechanisms. The results showed that triclopyr herbicide was effective in inhibiting weed growth at a dose of 670 g ha⁻¹ to 2,010 g ha⁻¹ in a greenhouse and a mixture of triclopyr and isopropylamine glyphosate herbicides at a dose of 670 g ha⁻¹ + 480 g ha⁻¹ to 1,340 g ha⁻¹ + 960 g ha⁻¹ effectively inhibited the growth of C. bicolor and C. zedoaria without disrupting the growth of sugarcane plants. However, the mixture of triclopyr and isopropylamine glyphosate herbicides at a dose of 1,340 g ha⁻¹ + 960 g ha⁻¹ caused mild to moderate poisoning in sugarcane plants. The interaction of herbicides showed a synergistic relationship. This study recommends the use of mixed herbicides in gardens that have high distribution and dominance of C. bicolor and C. zedoaria, further research is needed to optimize effectiveness and minimize the impact of toxicity on sugarcane plants.
