Abstract

Upaya untuk meningkatkan produktivitas jagung salah satunya adalah memodifikasi pertumbuhan tanaman melalui defoliasi yang merupakan pemangkasan daun pada tanaman jagung terutama daun-daun yang tidak produktif. Tujuan penelitian ini adalah untuk mengetahui respon pertumbuhan dan hasil  tanaman jagung (Zea mays subsp. mays L.) terhadap defoliasi daun pada umur tertentu. Metode yang digunakan dalam penelitian ini adalah eksperimen dengan menggunakan Rancangan Acak Kelompok (RAK) dan terdiri dari satu faktor dengan lima taraf dimana kontrol (tanpa perlakuan defoliasi); defoliasi daun pada 30 HST; defoliasi daun pada 40 HST; defoliasi daun pada 50 HST; defoliasi daun pada 60 HST. Faktor tersebut diulang sebanyak tiga kali sehingga akan menghasilkan 15 satuan percobaan. Hasil penelitian diperoleh bahwa umur terbaik untuk melaksanakan defoliasi pada tanaman jagung yaitu pada 30 hari setelah tanam (HST) saat tanaman baru memasuki fase vegetatif. Perlakuan defoliasi berpengaruh nyata pada variabel tinggi tanaman dari 42-80 HST dan komponen hasil jagung seperti bobot tongkol tanpa kelobot, bobot 100 butir biji kering, hasil aktual petak jagung, dan hasil potensial lahan jagung. Namun, perlakuan defoliasi tidak berpengaruh nyata pada variabel tinggi tanaman dari 14-35 HST, diameter batang, dan komponen hasil jumlah tongkol.

Abstract

Oil palm is known as a plantation crop that produces vegetable oil which is widely used in human life. Palm oil is produced from fresh fruit bunches (FFB) which originate from female flowers. Another part of the oil palm plant that has not been widely utilized is the oil palm leaves. When these leaves have been pruned, they will become abundant garden waste. Apart from that, there are empty palm oil bunches (tankos) which are classified as factory waste. Further research is needed regarding the compound content, especially the secondary metabolite content of midrib and tankos so that their utilization is optimal. The aim of this review is to determine the content of secondary metabolite compounds in oil palm plants and the potential for wider use. The method used is collecting library data, reading, analyzing and writing it down. The data and references used are scientific articles in national and international journals, textbooks, literature reviews and other sources. Based on the review, information was obtained that oil palm leaves contain several secondary metabolite compounds, especially saponins and phenols, while tankos contains phenol compounds. The amount of secondary metabolite compound content is not yet known for certain and this could be an opportunity to conduct research to determine the content of secondary metabolite compounds, especially for oil palm plants.
