Abstract

Indonesia is the second largest exporter of peanuts to Europe. One of the export requirements is that exported peanuts do not contain pests and high levels of pesticides. Aphis craccivora Koch. is the main pest in peanuts and controlled generally using pesticides which cause high pesticide levels. The aim of this research is to determine the application technique for biopesticide containing enthomopathogen (Streptomyces sp. and Trichoderma sp.) and chitosan which were expected to control the population of the pest Aphis craccivora and the intensity of plant damage. The research was conducted and designed using factorial completely randomized design where the first factor was application time (before and after pest investment). The second factor was chitosan concentration of 0.6%, 0.9%, and 1.2% in potato-sugar extract solution. Each treatment combination was repeated 4 times. The results obtained that the pre-investment application technique with a chitosan concentration of 1.2% was more capable of incrasing the mortality of the pest A. craccivora by up to 70% and the application of biopesticide before investment with a concentration of 1.2% had a lower level of damage, namely 38.25%.

Abstract

Penelitian ini bertujuan untuk mengetahui seberapa jauh perbedaan keanekaragaman jenis serangga pada tanaman tebu umur tanam 3 bulan (vegetatif) dan 10 bulan (generatif). Penelitian dilaksanakan Bulan April - Mei 2021. Tempat penelitian di pertanaman tebu Desa Sambirejo, Kecamatan Pare, Kabupaten Kediri, pada lahan pertama  tanaman tebu berumur 3 bulan memiliki luas 700 m2 dan lahan kedua tanaman tebu yang berumur 10 bulan seluas 2100 m2. Penentuan plot pengamatan menggunakan metode purposive sampling dan pengamatan menggunakan metode mutlak yaitu pengamatan secara langsung (visual) pada plot yang ditentukan, dimana pemilihan lahan tanaman tebu umur 3 bulan dan umur 10 bulan milik satu orang petani. Jarak tanaman yang digunakan yakni 60 cm dan ukuran bedengan pada lahan 100 cm. panjangnya disesuaikan dengan kondisi tanah, tinggi bedengan 30 cm,dan jarak antara bedengan 100 cm. Lahan tanaman tebu petak sampel secara sistematis pada garis diagonal sehingga didapatkan petak sampel sebanyak 5 plot dengan luasan 700 m2. Pengamatan serangga pada lahan tanaman tebu dilakukan 2 kali setiap  minggu, sehingga ada 12 kali pengamatan dalam kurun waktu 50 hari. Pengumpulan sampel serangga  di lapangan menggunakan alat perangkap seperti yellow trap, light trap,dan pitfall trap. Metode yang digunakan untuk kunjungan serangga menggunakan scan sampling, yaitu dilakukan pengamatan dan pengambilan sampel dalam dua periode waktu. Hasil analisis menggunakan indeks keanekaragaman, indeks dominasi, dan indeks kemerataan menunjukkan bahwa tidak ada perbedaan yang nyata keanekaragaman pada tanaman tebu umur 3 bulan dan umur 10 bulan

Abstract

 Low rice productivity due to the use of low-grade seeds. The quality of the seeds can suffer a decrease caused by the attack of pathogenic fungi carried by the seeds both at the time of planting and storage, which will have an impact on the disruption of plant growth. Biopriming using Trichoderma sp. be an effort to control because it is antagonistic to pathogens. The success of biopriming is also influenced by the duration of seed priming. This study aims to examine the duration of soaking rice seeds with Trichoderma sp. the most effective for lowering seed-borne pathogenic infections. The study was conducted by providing seed soaking treatment using Trichoderma sp. suspension for 6 hours, 12 hours, and 24 hours with PDA medium incubation test method and Growing on Test. The parameters tested are the percentage of infection rate and the percentage of germination. Identification results showed that pathogenic fungi carried by seeds included Rhizopus sp., Fusarium sp., Aspergillus sp., and Mucor sp. The results showed the duration of soaking rice seeds with Trichoderma sp. more effective in decreasing the infection rate is at a 24-hour duration. However, the duration of soaking rice seeds with Trichoderma sp. there was no noticeable difference for the percentage parameter of seed germination.
