Abstract

Kelompok tani Sawah Payo Nagari Gunung Rajo Kecamatan Batipuh, Kabupaten Tanah Datar mempunyai potensi dalam produksi pupuk organik, hal ini didukung oleh sisa hasil pertanianseperti jerami dan gulma tanaman pahitan Tithonia diversifolia, serta limbah peternakan (kotoran hewan) yang melimpah. Pemanfaatan limbah pertanian, tanaman gulma, maupun peternakan masih belum maksimal. Pengolahan limbah pertanian dan peternakan menjadi kompos yang dilakukan oleh sebagian besar petani di Nagari Gunung Rajo belum menggunakan proses fermentasi, sehingga hasil dan kualitasnya kurang maksimal. Tujuan kegiatan pemberdayaan kelompok tani ini adalah memberikan pengetahuan tentang proses pembuatan pupuk organik dari penyedian bahan baku, pembuatan bio-aktivator, dan pengemasan hasil produksi. Metode yang digunakan dengan pelatihan terstruktur dan praktik langsung pembuatan pupuk organik atau yang lebih dikenal dengan kompos. Hasil yang diperoleh dari kegiatan pemberdayaan ini adalah kelompok tani mampu membuat pupuk organik rizokompos berbahan limbah pertanian, gulma, limbah peternakan dan rizobakteri secara mandiri dengan kualitas hasil produksi yang baik yang mampu meningkatkan hasil pendapatan masyarakat setempat

Abstract

Forecasting of brown planthopper attack or BPH (Nilaparvata lugens Stal) using artificial intelligence and vegetation index of Sentinel-2 Satellite Imagery improves forecasting the incidence of hopperburn. This study aimed to determine the accuracy and correlation of the random forest classification of Sentinel-2 imagery to the incidence of hopperburn reported by Plant Pest Organisms Observer (PPOO) and determine the best method for predicting it. The study was done through observation and secondary data processing about the age of the plant, the incidence of hopperburn by BPH, interviews with farmers, and PPOO. The results showed that the hopperburn NDVI index ranged from 0.23 - 3.8. The random forest classification accuracy was high (Kappa Index = 0.82). The relationship between the hopperburn area from the PPOO report and the predicted area from Sentinel-2 images classified as (R2 = 0.53, R = 0.728) with the equation Y = -1.5 + 0.82 X. The correlation can be improved using spatial regression Geographically Weighted Regression (GWR4) with the best gaussian distance of 1.76 km (R2 = 0.6, R = 0.77). The best prediction for the NDVI stage of hopperburn attack time series with random forest (RMSE = 0.12819) was better than the prediction of the hopperburn attack time series with the exponential smoothing method from the PPOO report (RMSE 3.302184).

Abstract

Some flowering plants like common zinnia (Zinnia elegans (Jacq) Kuntze), marigold (Tagetes erecta Linnaeus), and cockscomb flowers (Celosia sp.) have been used as refugia and conservation plants for predators and parasitoids but are still not yet optimal. Planting refugia plants can affect insect diversity and evenness index, affecting the stability and balance of the agroecosystem. The study aimed to determine the effect of common zinnia, cockscomb flowers, and marigold as refugia on insects’ diversity and evenness index and their potential as a medium for conservation of predators and parasitoids. The study was conducted in organic rice fields in Batang Anai Sub-district, Padang Pariaman District, West Sumatra, from May to July 2020. The Insect was collected from plots covering an area of ??48 m2 and identified in the Bioecology laboratory, Faculty of Agriculture, Universitas Andalas. Planting common zinnia, marigolds, and cockscomb flowers increased the index of diversity and evenness of insects around rice fields. The index of diversity and evenness of insects on cockscomb flowers (H = 2.90) was higher than that of common zinnia (H = 2.61) and marigold (H = 2.63). Cockscomb flowers have more potential as a medium for conserving predators and parasitoids.
