| dc.description.abstract | ALFAN ADRIAN. Efikasi Beberapa Bahan Aktif Herbisida Tunggal dan Kombinasinya terhadap Pengendalian Gulma di Kebun Teh (Camellia sinensis L.). Dibimbing oleh SOFYAN ZAMAN.
Gulma dapat menurunkan produksi pucuk teh hingga lebih dari 40% sehingga pengendalian kimiawi diperlukan. Penelitian ini bertujuan mengidentifikasi dominansi gulma serta menguji efikasi herbisida tunggal dan kombinasinya di PT Kabepe Chakra, Kabupaten Bandung. Gulma dominan sebelum aplikasi adalah Ageratum conyzoides (SDR 37,00%), diikuti Crassocephalum crepidioides (12,46%) dan Borreria latifolia (11,46%). Setelah aplikasi terjadi pergeseran komposisi gulma dengan nilai koefisien komunitas 71,87% yang mengindikasikan komunitas bersifat heterogen, ditandai meningkatnya dominansi Setaria palmifolia dari 7,62% menjadi 20,48% akibat selektivitas herbisida. Perlakuan IPA glifosat 2 L ha-1 + metil metsulfuron 25 g ha-1 terbukti paling efektif menekan bobot basah gulma paling rendah hingga 27,00 g m-2 dan persentase penutupan gulma terendah 13,00% pada 3 MSA, serta 40,00% pada 6 MSA. Seluruh perlakuan tidak menimbulkan fitotoksisitas pada tanaman teh. Perlakuan terbaik membutuhkan biaya Rp 240.000 ha?¹ sehingga efektif sekaligus cukup efisien secara ekonomi.

| dc.description.abstract | ALFAN ADRIAN. Efficacy of Several Single and Combined Herbicide Active Ingredients for Weed Control in Tea Plantation (Camellia sinensis L.). Supervised by SOFYAN ZAMAN.
Weeds can reduce tea shoot production by more than 40%, making chemical weed control necessary. This study aimed to identify weed dominance and evaluate the efficacy of single and combined herbicides at PT Kabepe Chakra, Bandung Regency. The dominant weed species before herbicide application was Ageratum conyzoides (SDR 37,00%), followed by Crassocephalum crepidioides (12,46%) and Borreria latifolia (11,46%). Herbicide application resulted in a shift in weed composition, with a community coefficient value of 71,87%, indicating a heterogeneous weed community. This shift was characterized by an increase in the dominance of Setaria palmifolia from 7,62% to 20,48%, likely due to herbicide selectivity. The treatment of glyphosate IPA 2 L ha-1 + metsulfuron-methyl 25 g ha-1 was the most effective in suppressing weeds, resulting in the lowest weed fresh weight of 27.00 g m-² and the lowest weed cover percentage of 13.00% at 3 WAA and 40.00% at 6 WAA. None of the herbicide treatments caused phytotoxicity to tea plants. The best treatment required a cost of only IDR 240.000 ha-1, indicating both effective weed control and economic efficiency.
