Abstract

Fusarium oxysporum merupakan penyakit penting pada bawang merah. Gejala khas yang ditimbulkan berupa daun yang memelintir sehingga penyakit ini dikenal dengan sebutan penyakit moler. Pengendalian yang paling sering digunakan adalah dengan menggunakan pestisida kimia. Memperhatikan dampak negatif dari pestisida kimia berupa kerusakan lingkungan dan terancamnya kesehatan makhluk hidup non target maka salah satu solusinya adalah dengan menggunakan pestisida nabati yang ramah lingkungan dan lebih aman seperti memanfaakan kulit buah durian. Kulit buah durian telah dikonfirmasi mengandung senyawa yang bersifat sebagai antifungi. Oleh karena itu, penelitian ini dilakukan untuk mengetahui potensi kulit durian dalam bentuk serbuk sebagai pestisida nabati untuk mengendalikan penyakit F. oxysporum pada tanaman bawang merah. Penelitian dilakukan dalam 2 tahap yaitu in vitro dan in vivo. Metode penelitian yang dilakukan pada in vivo adalah Rancangan Acak Kelompok (RAK) dengan 5 perlakuan (kontrol negatif (Inokulasi F. oxysporum), kontrol positif (F. oxysporum+Fungisida (Benomil), Serbuk kulit durian 0,125 kg/ha + F. oxysporum, Serbuk kulit durian 0,25 kg/ha + F. oxysporum, Serbuk kulit durian 0,375 kg/ha+ F. oxysporum) dan 4 kali ulangan. Hasil penelitian menunjukkan serbuk kulit durian berpotensi dijadikan sebagai pestisida karena mampu menghambat pertumbuuhan F. oxysporum baik secara in vitro ataupun in vivo.

Abstract

Plant Pest Organisms that often attack mustard are Tritip caterpillar (Plutella xylostella L), armyworm (Spodoptera litura F), growing point caterpillar (Crocidolomia binotalis Zel), common pests that often attack mustard, namely Leaf Grasshopper (Phyllium pulchrifolium), Nezara viridula L, and Chrysodeixis chalcites. One of the environmentally friendly pest control techniques is the use of pesticides derived from plants which are commonly called biopesticides. Patikan kebo (Euphorbia hirta L) was known to contain antibacterial active compounds that can be used as organic herbicides. This study used patikan kebo extract with several concentrations to suppress the attack of mustard leaves destroying pests. The research took place in a vegetable growing area and was carried out for 40 days from sowing to harvesting. The research was conducted using an experimental method. The results of this study showed that all treatments of patikan kebo extract were able to suppress the attack of mustard leaf pests and the use of a very significant concentration was found in (7.5 ml) with the lowest attack intensity of 4.79%.

Abstract

Field rats can be controlled by biological control, technical culture, physical mechanics or chemistry, while the most effective and efficient way is to use traps, in addition to reducing environmental pollution. This method is also safe and economical and can be used repeatedly. This control also uses bait to attract rats, bait used by rice field crabs, salted tuna, roasted coconut, roasted coconut and shrimp paste. This study aims to determine the bait that can attract the attention of field rats in semi-automatic traps and the benefits of being able to provide information for farmers to overcome rice field rat pests by using bait to attract rats into the trap. The research method used was a one-factor Completely Randomized Design (CRD) experiment with 5 treatments. The results showed that the treatment of each bait seen statistically had no significant effect, but the baits that were preferred by rice field rats were roasted coconut and roasted coconut. This bait can trap three species of rats, namely Rattus exulans, Rattus rattus diardii and Rattus argentiventer.

Abstract

Plant Pest Organisms (PPO) that have recently become a problem in corn cultivation are Fall Armyworm (FAW) or the armyworm Spodoptera frugiperda J. E. Smith. The damage of S. frugiperda on sweet corn and feed is thought to be different and is not yet known. This study aims to determine the level of destruction of S. frugiperda on sweet corn and feed with control treatment of biological pesticides on papaya leaves and garlic, 30 ml/l water, 40 ml/l water, and 50 ml/l water. This study used a completely Randomized Design (CRD) with two factors. Corn varieties and concentrations of vegetable pesticides. The treatments used in this study were water control, chemical control, and three treatments of biological pesticide concentration with four replications. The results of observations 1-3 (age 0-2 weeks after planting/ WAP) have not found an attack, occurred on the study to 4-7 (age 3-6 WAP). Pesticides of papaya leaf and garlic affected the destructive power of S. frugiperda, where the concentration factor on the incidence of attack and attack intensity had a very significant effect, an interval of the variety factor had to make a difference on the incidence of attack but did not significantly affect the potency of the attack. The 50 ml/l concentration treatment on sweet corn and feed varieties was the best in suppressing the percentage of attack (12.50; 23.40%), attack intensity (5.92; 8.00%), and damage to the cob (1.79); 4.79%).
