Abstract

This research was conducted to determine the dose of shallot skin extract that is effective for controlling Spodoptera litura F. This research was carried out for 2 months at the Biology Laboratory, Faculty of Agriculture, Santo Thomas Catholic University, Medan. The research design used was a Non-Factoral Completely Randomized Design (CRD) consisting of five treatments and each treatment was repeated four times to form 20 experimental units of Red Onion Skin Soaking (K), namely: K0 = 0% (Control), K1 = 20 gr/liter of water, K2 = 40 gr/liter of water, K3 = 60 gr/liter of water, and K4 = 80 gr/liter of water. The parameters observed were pest mortality, 50% death time and larval behavior after application. From the research results, it can be seen that administering shallot skin extract at the highest dose, namely 80 g/L, can be quadratically used as a botanical insecticide to control S. litura pests with a death time of 27 hours

Abstract

This research aims to determine the effect of shallot extract concentration and soaking time on the growth of pepper plant stems. This research was carried out at the Unika Santo Thomas Medan agricultural experimental field Jl. Setia Budi no. 479, Tanjung Sari, Medan. With a height of around 32 meters above sea level (meters above sea level). This research was conducted from March to May 2023. This research used a factorial Randomized Block Design (RAK) consisting of 2 factors. The first factor is the concentration of shallot extract (K) and the second factor is the soaking time (P). The first factor is the concentration of shallot extract (K) consisting of 4 treatment levels, namely: K0: 0% (control), K1: 30% (30 mL of shallot extract + 70 mL of distilled water), K2: 60% (60 mL of shallot extract + 40 mL distilled water), K3: 90% (90 mL shallot extract + 10 mL distilled water). The second factor is the length of soaking of pepper plant cuttings (P) consisting of 3 treatment levels, namely: P1: 3 hours, P2: 6 hours, P3: 9 hours. Based on the research results, it can be seen that the concentration of onion extract has no effect on the percentage of live cuttings of pepper plant cuttings, but it has a real influence on the length of the shoots with the highest shoots obtained at a concentration of 93.33% at a concentration of 83.77% for the number of leaves. the most. Regarding the number of roots, a concentration of 78.66% produced the highest number of roots.
PENGARUH PEMBERIAN PUPUK ORGANIK DAN ANORGANIK TERHADAP PERTUMBUHAN, PRODUKSI DAN PERSENTASE SERANGAN HAMA GANJUR (Orseolia oryzae) PADA TANAMAN PADI (Oryza sativa L.) Arkhiadi Benauli; Sitohang, Nurdin; Yunda Gusriani; Hutasoit, Jaya Febrianto

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh pemberian pupuk dalam menekan persentase serangan Orseolia oryzae pada tanaman padi. Metode dalam penelitian ini menggunakan rancangan acak kelompok (RAK) dengan perlakuan sebagai berikut: F0: kontrol; F1: Kotoran sapi; F2: Pupuk Organik Kompos; F3: Pupuk NPK Tunggal, P4 : Pupuk NPK Majemuk (16:16:16). Penelitian dimulai dengan pembuatan pupuk organik (kotoran sapi dan kompos), penanaman, penerapan perlakuan, pengumpulan data, dan analisis data observasi. Hasil penelitian menunjukkan bahwa pemberian pupuk meningkatkan jumlah anakan, jumlah malai, bobot 1000 butir, produksi per plot dan menurunkan persentase serangan hama Ganjur (Orseolia oryzae). Kotoran sapi adalah perlakuan terbaik.
