Abstract

The use of chemical pesticides at the level of vegetable farmers is indicated in excessive amounts, while this is very dangerous for both the environment and humans. Chemical pesticides can pollute the environment because they are toxic and overused. Curry leaves (Murrayakoeginii) and Javanese chili (Piper retrofractum) can kill larvae, are safe for animals, and safe for the environment. Objective: To determine the effectiveness of methanol extract of curry leaves (Murraya koeginii) and Javanese chili (Piper retrofractum) against Crocidolomia pavonana Zell larvae. Research method: using a completely randomized design (CRD) with a factorial pattern consisting of two factors, namely the extraction material factor (I) consisting of 2 levels, namely I1 = Javanese Chilli Extract, I2 = Curry Leaf Extract. Furthermore, the extract concentration factor (K) which consists of five levels. The concentration of the extract was determined based on the results of preliminary testing of the test larvae which could cause 15% and 50% mortality of the larvae. Thus, 10 treatment combinations were obtained, each treatment was repeated 3 times, so there were 30 experimental units. In each petri dish, 10 C. pavonana larvae will be introduced, so that the total number of petri dishes is 30 plates along with 300 C.pavonana imago and all of them are observed. Results: Statistical analysis found that to control C. pavonana larvae, Java chili (Piper retrofractum) extract (I1) with a concentration of 0.35% (K1) could be used.

Abstract

This study aims to determine the effectiveness of several isolates of Trichoderma sp. in controlling White Root Fungus disease in rubber plants, knowing the percentage of inhibition of various isolates of Trichoderma sp. against White Root Fungus disease on rubber plants, as well as knowing the growth area of Trichoderma sp. against White Root Fungus disease using Potato Dextrose Agar media with Dual Culture method. Plant disease is a limiting factor on plant growth and development, White Root Fungus disease caused by the pathogen Rigidoporus lignosus has been reported to cause losses to rubber plants Biological control with Trichoderma sp. is disease control by involving the manipulation of beneficial natural enemies to obtain a reduction in population numbers and the status of pests and diseases in the field. This study used the experimental method at the Sungei Putih Research Unit Laboratory using a non-factorial Completely Randomized Design (CRD) consisting of 4 replications. As a treatment, isolate of the endophytic fungus Trichoderma sp. and the isolate tested for antagonism was White Root Fungus. The T2 treatment obtained good effectiveness in suppressing the growth of White Root Fungus with an average inhibition percentage of Trichoderma sp. against White Root Fungus at 8 HSI the highest was obtained in the T2 treatment which was 76.65% and the lowest was in the T0 treatment which was 2.86%. The growth area of Trichoderma sp. the highest at 8 HSI was found in the T2 treatment which was 42.64 cm and the lowest was in the T0 treatment which was 2.86 cm.

Abstract

Kendala dalam budidaya padi ialah rendahnya produktivitas. Dalam upaya peningkatan produktivitas padi, beberapa input teknologi dicoba di lapangan termasuk metode Hazton. Hazton adalah metode penanaman padi yang dirancang untuk meningkatkan produksi dengan menggunakan lebih banyak benih/lubang tanam. Penelitian ini bertujuan mengevaluasi pengaruh umur bibit dan jumlah bibit terhadap pertumbuhan dan produktivitas padi sawah. Penelitian menggunakan rancangan petak terbagi (RPT) dengan desain faktorial 3x3 dan empat ulangan. Faktor pertama adalah umur bibit padi (U), yang terdiri dari tiga taraf: U1 = 20 hari setelah tanam (HST), U2 = 25 HST, dan U3 = 30 HST. Faktor kedua adalah jumlah bibit/lubang tanam (J) pada juga terdiri dari tiga taraf, yaitu J1 = 20 bibit/lubang (kepadatan rendah), J2 = 25 bibit/lubang (kepadatan sedang), dan J3 = 30 bibit/lubang (kepadatan tinggi). Hasil penelitian menunjukkan bahwa Perlakuan umur bibit U1 (20 HST) merupakan perlakuan umur bibit terbaik dengan tanaman paling tinggi, jumlah anakan/rumpun paling banyak, produksi gabah dan 1000 butir gabah paling berat dibanding perlakuan umur bibitU2 (25 HST) dan U3 (30 HST). Sementara perlakuan jumlah bibit/lubang tanam J1 (20 bibit/lubang tanam) dan J2 (25 bibit/lubang tanam) lebih baik dibanding perlakuan J3 (30 bibit/lubang tanam) dalam produksi gabah dan 1000 butir gabah. Temuan ini dapat memberikan panduan bagi petani untuk meningkatkan hasil dan efisiensi dalam budidaya padi.

Abstract

Anggur memiliki prospek yang baik di Indonesia. Kendala pengembangan tanaman anggur adalah ketersediaan bahan tanam yang berkualitas baik. Upaya menyediakan bahan tanam anggur salah satunya adalah dengan stek batang. Pemberian zat pengatur tumbuh dapat meningkatkan persentase pertumbuhan stek. Tujuan penelitian ini untuk mengetahui pengaruh pertumbuhan dan hasil tanaman stek anggur terhadap interaksi zat perangsang akar dan pupuk organik. Penelitian dilakukan di kebun percobaan Fakultas Pertanian Universitas Samudra pada Maret-Mei 2023. Penelitian menggunakan Rancangan Acak Kelompok (RAK) faktorial. Faktor pertama adalah zat perangsang akar yang terdiri 3 taraf yaitu air kelapa, madu dan ekstrak bawang merah. Faktor kedua yaitu pupuk kandang yang terdiri 4 taraf: pupuk kandang sapi, pupuk kandang ayam, pupuk kandang kambing dan kascing. Hasil penelitian menunjukkan bahwa tidak terdapat pengaruh interaksi kedua faktor perlakuan. Perlakuan jenis zat perangsang akar berpengaruh tidak nyata terhadap semua parameter pengamatan, sementara perlakuan jenis pupuk kandang berpengaruh nyata terhadap persentase tumbuh. Perlakuan K4 (pupuk kascing) mengakibatkan persentase tumbuh stek anggur lebih tinggi dibanding pupuk kandang sapi dan ayam, tetapi tidak berbeda dengan pupuk kandang kambing.

Abstract

[The Potential of Endophytic Bacteria as a Biological Controller of Leaf Fall Disease Caused by Pestalotiopsis sp. IN Rubber Plants (Hevea brasiliensis Muell. Arg.]. This study aims to explore endophytic bacteria and determine their effectiveness against the fungus Pestalotiopsis sp. which causes leaf fall on rubber plants. Pestalotiopsis sp. can attack all rubber clones resulting in decreased latex production. The presence of pathogen attacks can result in enormous economic losses. Therefore, it is very important to find an effective and efficient controlling method, one of which is through biological control of plant diseases, namely by using antagonistic microorganisms. The presence of endophytic bacteria as biological controllers has become an alternative method to reduce the practices of chemical control. This study used a Non-Factorial Completely Randomized Design (CRD) with 6 treatments and 4 replications, so that 24 experimental units were obtained, using Potato Dextrose Agar (PDA) media for the in vitro antagonist test using the dual culture method. Namely P₀ = Control, P₁ = Pestalotiopsis sp. 1 vs Bacteria P, P₂ = Pestalotiopsis sp. 2 vs Bacteria B, P₃ = Pestalotiopsis sp. 3 vs Bacteria C, P₄ = Pestalotiopsis sp. 4 vs Bacteria E, P₅ = Pestalotiopsis sp. 5 vs Bacteria F. The results indicated that antagonistic treatment of endophytic bacteria in vitro affected the percentage of inhibitory power of the mycelium of the fungus Pestalotiopsis sp. by endophytic bacteria at 1 - 6 Days After Incubation (DAI). The 3% KOH method and gram staining showed that samples P₁, P₂, P₅ did not produce mucus and were purple in colour (positive), but samples P₃, P₄, showed mucus and were pink in colour (negative). Hypersensitivity reactions to tobacco plants samples P₁, P₂, P₃, P₄, P₅ did not show negative characteristics or did not cause changes in coloration and symptoms on leaves of tobacco plant.
