      Abstract
      BOBY ASIKIN JEREMIA MANALU. Uji Efikasi Herbisida Triklopir dan Glifosat terhadap Gulma Clidemia hirta di Kelapa Sawit (Elaeis guineensis Jacq.). Dibimbing oleh HARIYADI. Penelitian ini bertujuan mengevaluasi efektivitas herbisida triklopir dan glifosat terhadap Clidemia hirta pada perkebunan kelapa sawit berdasarkan gejala awal fitotoksisitas, daya fitotoksisitas, dan waktu menuju kematian gulma. Penelitian dilaksanakan pada Agustus sampai Desember 2025 di PT PP London Sumatra Indonesia Tbk., Sei Gemang Estate, Kabupaten Musi Rawas Utara, Sumatera Selatan. Penelitian menggunakan rancangan kelompok lengkap teracak (RKLT) faktor tunggal yang terdiri atas enam perlakuan dan tiga ulangan. Hasil penelitian menunjukkan bahwa perlakuan herbisida memberikan pengaruh nyata terhadap daya fitotoksisitas gulma Clidemia hirta. Perlakuan T3 (triklopir 4,67 ml/l) memberikan hasil terbaik dengan gejala awal fitotoksisitas pada hari ke-3, mencapai fitotoksisitas 100% pada 5 minggu setelah aplikasi (MSA), dan menyebabkan kematian gulma pada 5 MSA. Pada kelompok glifosat, perlakuan G1 (glifosat 3,67 ml/l) merupakan perlakuan terbaik dengan daya fitotoksisitas mencapai 100% dan kematian gulma pada 5 MSA. Secara keseluruhan, triklopir lebih efektif dibandingkan glifosat dalam mengendalikan Clidemia hirta.
       
      BOBY ASIKIN JEREMIA MANALU. Herbicide Efficacy of Triclopyr and Glyphosate Against Clidemia hirta in Oil Palm (Elaeis guineensis Jacq.). Supervised by HARIYADI. This study aimed to evaluate the effectiveness of triclopyr and glyphosate herbicides in controlling Clidemia hirta in oil palm plantations based on the onset of phytotoxicity symptoms, the level of phytotoxicity, and the time required for weed mortality. The study was conducted from August to December 2025 at PT PP London Sumatra Indonesia Tbk., Sei Gemang Estate, Musi Rawas Utara Regency, South Sumatra, Indonesia. The experiment employed a randomized complete block design (RCBD) with a single factor consisting of six treatments and three replications. The results showed that herbicide treatments significantly affected the phytotoxicity level of Clidemia hirta. Treatment T3 (triclopyr at 4.67 ml/l) produced the best results, with the earliest phytotoxicity symptoms appearing on the third day after application, reaching 100% phytotoxicity at 5 weeks after application (WAA), and causing weed mortality at 5 WAA. Among the glyphosate treatments, G1 (glyphosate at 3.67 ml/l) was the most effective, achieving 100% phytotoxicity and weed mortality at 5 WAA. Overall, triclopyr was more effective than glyphosate in controlling Clidemia hirta.
