Abstract

This study aims to reduce the use of chemical pesticides in controlling the pest Tirathaba mundella by using biological agent Beauveria bassiana on oil palm plants. The making of Beauveria bassiana fungi isolates was carried out at the Laboratory of Plantations and Protection of Medan Plantations, and PT Cisadane Sawit Raya as the place for the research. The study used nonfactorial randomized block design (RAK) using a trial object of 21 samples of oil palm plants which were divided into 7 treatments and 3 replications, where D0 (control) was given aquadest, D1 was treated with B.bassiana suspension at a dose of 10 gr/m , D2 was treated with B.assiana suspension at a dose of 20 gr/ml, D3 was treated with B. bassiana suspension at a dose of 30 gr/ml, D4 was treated with B. bassiana suspension at a dose of 40 gr/ml, D5 was treated with B. bassiana suspension with a dose of 50 gr/ml, D6 was treated with B. bassiana suspension at a dose of 60gr/ml. Pests experienced total death on day 5 after application in treatment D5 and D6. The percentage analysis of mortality showed that on day 5 caused a very significant effect with 100% death time occurring in all oil palm bunches samples after ≥ 5 HSA.

Abstract

Penelitian ini bertujuan untuk mengetahui respon pertumbuhan dan hasil beberapa varietas tanaman kedelai hitam pada tanah salin dengan pemberian antioksidan. Penelitian ini menggunakan rancangan acak kelompok factorial (RAK Faktorial), yang terdiri dari 2 faktor yaitu Varietas Black Soybean yang terdiri dari tiga taraf yaitu : V1 : Detam 2, V2 : Detam 3, V3 : Detam 4 dan jenis antioksidan yang tediri dari dari 3 taraf yaitu A0 : Kontrol, A1 : Asam Askorbat (1000 ppm), A2 : Tocopherol (500 ppm). Parameter yang dihitung antara lain tinggi tanaman, jumlah cabang, jumlah klorofil, berat biji per tanaman, berat piji per plot, dan berat 100 biji. Hasil analisa data menampilkan bahwa pemberian beberapa antioksidan berpengaruh nyata terhadap parameter pengamatan jumlah cabang namun tidak berpengaruh nyata terhadap tinggi tanaman, jumlah klorofil, bobot biji per tanaman, bobot biji per plot dan bobot 100 biji dan perlakuan beberapa varietas berpengaruh nyata terhadap semua parameter serta interaksi antara dua perlakuan yang diberikan berpengaruh nyata hanya pada parameter jumlah cabang.Kata Kunci: Asam Akorbat, Detam, Kacang Kedelai Hitam, Salinitas, Tocoperol
