Abstract

The functional response of predatory bird, Lanius sp. (Passeriformes: Laniidae) on migratory locust [Locusta migratoria manilensis (Orthoptera: Acrididae)] had been studied under restricted condition. The migratory locusts were reared in the green house. Second and fourth nymph instars along with adult stages of the migratory locust were used in this trial. Maximum feeding and functional response of the predatory bird against the migratory locust were determined. Research protocol used follows Holling’s model. Results showed that the maximum feeding of the predatory bird was very high i.e. against 2nd and 4th instars and adult of the locust were 2.75 preys/minute, 0.13 preys/minute, and 0.09 preys/minute; respectively. The relationship between predatory bird and migratory locust fitted with the Holling’ s type 2 functional response. The high feeding rate of the predatory bird revealed that the bird is a promising candidate of biological control agent on migratory locust.

Abstract

Effectiveness of entomopathogenic nematodes Steinernema spp. against mortality of larvae and pupae of Spodoptera exigua Hubner (Lepidoptera: Noctuidae) was evaluated in the Laboratory of Nematology and Biological Control at the Faculty of Agriculture, Gadjah Mada University. The most virulent isolate of the nematode was selected amongst isolates from Solo, Jombang, and Medan. The effectiveness was determined by analising mortality of the S. exigua that was treated with Steinernema spp. at concentration rates of 0, 50, 100, 200, 400 infective juvenil (IJ) per 1.5 mL aquadest. Inoculation of the nematode was done by filter paper method. Results showed that all isolates were able to infect the third instar of S. exigua. Solo and Jombang isolates caused relative similar in mortalities ca. 98 and 94%, and significantly higher than Medan isolate ca. 86. Hence, the Solo isolate was preferred for efficacy against the insect larvae and pupae. The mortality of S. exigua due to the Steinernema spp. was influenced by the insect instars. The insect mortality-rates of L1, L2, and pupae were 13,3; 6.6 - 13,3; 23,3 - 60% and lower than those of L3, L4, and L5 ca. 41,6 - 75; 46,6 - 60; and 66,6 - 90%, respectively. The nematode concentration-rates did not influenced the mortality of L1, L2, L3, L4, and pupae but it significantly influenced the L5 mortality. The concentration rate of 200 IJ per 1.5 ml aquadest caused the highest mortality.

Abstract

Kajian ini bertujuan untuk mengetahui hubungan antara respons petani dengan upaya pengendalian penyakit blas (Pyricularia oryzae). Kajian dilaksanakan pada bulan Februari – Juli 2019 di Desa Sumberharjo, Kecamatan Prambanan, Kabupaten Sleman. Kajian bersifat deskriptif dengan teknik survei dan pengambilan sampel secara propotional random sampling pada petani yang pernah mengikuti kegiatan SL-PHT. Analisis data menggunakan korelasi Rank Spearman. Hasil kajian menunjukkan bahwa respons petani pada komponen kognitif, afektif, dan konatif semua termasuk kategori tinggi, sedangkan upaya pengendalian termasuk kategori sedang. Hasil uji korelasi Rank Spearman untuk respons kognitif, afektif, dan konatif masing-masing sebesar 0,387, 0,333, dan 0,447 signifikan pada taraf kepercayaan 0,05 dan 0,01. Artinya bahwa petani sangat respons dengan upaya pengendalian penyakit blas tetapi belum maksimal dalam penerapannya. Upaya yang dilakukan agar penerapan blas pengendalian dilakukan secara optimal adalah dengan pemberdayaan petani dalam pencegahan munculnya penyakit salah satunya dengan pemupukan sesuai rekomendasi.

Abstract

The use of Plant Growth Promoting Rhizobacteria (PGPR) as a biofertilizer is an alternative fertilization method that can enhance soil fertility and reduce environmental pollution caused by excessive use of chemical fertilizers. This study aims to analyze the influence of age (X1), education level (X2), farming experience (X3), the role of agricultural extension workers (X4), and the role of farmer groups (X5) on the adoption level of PGPR (awareness, interest, evaluation, trial, adoption). The research was conducted in Tirtomartani Village, Kalasan, Sleman, Yogyakarta Special Region, from November 2024 to April 2025, using a quantitative approach through a survey method with questionnaires administered to 38 respondents. The analysis results showed that all independent variables (X) simultaneously had a significant effect on the adoption level of PGPR. However, partially, only the role of farmer groups had a significant influence. Therefore, empowering farmer groups is essential, particularly in raising farmers’ awareness through training on the production and application of PGPR, as an effort to improve their knowledge, attitudes, and skills in using biofertilizers.   Keywords: Adoption Rate, Rice Farmer, PGPR.

Abstract

Petani di Kalurahan Srimartani menerapkan budidaya pertanian dengan menggunakan pupuk kimia secara terus menerus yang mengakibatkan penurunan kualitas tanah. Petani belum mampu membuat pupuk organik karena keterbatasan pengetahuan sehingga mengakibatkan tingginya biaya pemupukan. Maka dari itu, perlu adanya penyuluhan pembuatan pupuk organik agar petani mampu mengadopsi hasil dari penyuluhan untuk diterapkan pada kegiatan budidayanya. Penelitian ini bertujuan untuk menganalisis peningkatan pengetahuan, sikap, dan keterampilan petani. Metode yang digunakan adalah eksperimen. Pelaksanaan penyuluhan menggunakan pendekatan ceramah, diskusi, dan praktik langsung. Peserta penyuluhan berjumlah 20 petani. Evaluasi tingkat ketercapaian keberhasilan penyuluhan dilakukan dengan pemberian kuesioner pre-test dan post- test dan diolah menggunakan model evaluasi Kirkpatrick. Hasil penelitian menunjukkan bahwa Level 1 atau reaksi dari peserta menunjukkan nilai 31,3 artinya peserta merasa puas dengan persiapan yang dilakukan oleh narasumber. Evaluasi level 2 adalah pembelajaran yang diukur dengan pre-test dan post-test, menunjukan peningkatan pengetahuan sebesar 23%; sikap 7%; dan keterampilan 86%. Efektivitas Penyuluhan (EP) dalam meningkatkan pengetahuan adalah 24% (kategori kurang efektif), sikap 9% (kategori kurang efektif), dan keterampilan (pupuk) 90% (kategori efektif). Efektivitas perubahan perilaku pengetahuan adalah 58% (kategori cukup efektif), sikap 50% (kategori cukup efektif), dan keterampilan 90% (kategori efektif). Tahap evaluasi level 3 dilakukan dengan pengukuran perubahan perilaku peserta setelah mengikuti kegiatan penyuluhan yang dinilai dari keterampilan peserta penyuluhan dalam membuat POC. Pada tahap evaluasi level 3 terdapat 3 kelompok yang berhasil dan 1 kelompok gagal melakukan fermentasi.
