| dc.description.abstract | Penelitian bertujuan menganalisis pengaruh konsentrasi isopropilamina glifosat, konsentrasi metil metsulfuron, dan dosis larutan per pohon terhadap persentase kerusakan tajuk, skor kerusakan tanaman, dan waktu kematian kelapa sawit liar, menganalisis hubungan antarvariabel efektivitas pengendalian, serta menentukan kombinasi perlakuan terbaik menggunakan metode technique for order preference by similarity to ideal solution (TOPSIS). Penelitian menggunakan tiga taraf konsentrasi isopropilamina glifosat, yaitu 250, 500, dan 750 ml l?¹, dua taraf konsentrasi metil metsulfuron, yaitu 0,5 dan 1,0 g l?¹, serta dua taraf dosis larutan, yaitu 50 dan 100 ml per pohon sehingga diperoleh 12 kombinasi perlakuan yang diaplikasikan pada tiga kelompok diameter batang kelapa sawit liar, yaitu 24–78 cm, 97–146 cm, dan 147–242 cm. Analisis TOPSIS menunjukkan bahwa kombinasi perlakuan G3M2P1 (isopropilamina glifosat 750 ml l?¹, metil metsulfuron 1,0 g l?¹, dan dosis larutan 100 ml per pohon) merupakan alternatif terbaik pada seluruh kelompok diameter batang dengan nilai preferensi tertinggi sehingga direkomendasikan sebagai kombinasi perlakuan paling efektif untuk pengendalian kelapa sawit liar melalui metode injeksi batang. | |
| dc.description.abstract | This study aimed to analyze the effects of isopropylamine glyphosate concentration, methyl metsulfuron concentration, and solution dosage per palm on canopy damage percentage, plant damage score, and mortality time of wild oil palm, as well as to determine the best treatment combination using the technique for order preference by similarity to ideal solution (TOPSIS). The experiment consisted of three isopropylamine glyphosate concentrations (250, 500, and 750 ml l?¹), two methyl metsulfuron concentrations (0.5 and 1.0 g l?¹), and two solution dosages (50 and 100 ml per palm), resulting in 12 treatment combinations applied to three stem diameter classes (24–78 cm, 97–146 cm, and 147–242 cm). The TOPSIS analysis identified G3M2P1 (750 ml l?¹ isopropylamine glyphosate, 1.0 g l?¹ methyl metsulfuron, and 100 ml solution per palm) as the best treatment across all stem diameter classes, indicating its superior effectiveness for controlling wild oil palm through the stem injection method. | |
