Abstract

Rice farmers in Besur Village planted four species of refugia plants around rice plants to enhance biological control as a part of Healthy Plant Management Program. These refugia plants were flowering plants i.e., Cosmos sulphureus, Helianthus annuus, Zinnia elegans, and Sesamum indicum. The objective of this research was to observe the Arthropods associating with these refugia plants. This research was conducted in December 2017 to March 2018 at Besur Village, Lamongan District, East Java Province. Samples were obtained from each refugia species by branches beating, sweep net, pitfall trap, and direct observation method in the vegetative, generative, and postharvest periods paddy plant. The results showed that Arthropods associated with refugia plants are mostly belong to the order of Diptera, Hymenoptera, and Araneae. Detritivore group was the most abundant in all periods. Analysis of the diversity and similarity of all refugia species showed moderate to high values with high similarities each other. Keywords: beneficial insect, flower, healthy plant management, integrated pest management, paddy field

Abstract

Petugas pengendali organisme pengganggu tumbuhan (OPT) pegawai negri sipil memiliki tugas pokok dan fungsi melakukan pengamatan, pengendalian OPT dan dampak perubahan iklim. Provinsi Jawa Barat hanya memiliki 122 orang petugas pengendali organisme pengganggu tumbuhan pegawai negri sipil, 123 orang petugas pengendali organisme pengganggu tumbuhan tenaga harian lepas yang membawahi 626 kecamatan. Jumlah tersebut setiap tahunnya akan terus berkurang, sehingga wilayah pengamatan setiap petugas akan menjadi lebih luas yang berakibat menurunnya tingkat efisiensi, akurasi, dan efektivitas pengamatan di lapangan. Penelitian ini bertujuan mengevaluasi kinerja petugas POPT di era digital saat ini dalam melakukan pengamatan dan peramalan OPT. Metode penelitian yang digunakan adalah metode penentuan responden berdasarkan teknik purposive sampling, responden merupakan petugas POPT dengan jumlah 30 petugas. Hasil wawancara dianalisis secara deskriptif melalui metode Analytical Hierarchy Process (AHP) menggunakan software Expert Choice. Hasil penelitian menunjukkan bahwa keberadaan Petugas pengendali organisme pengganggu tumbuhan di Kabupaten Subang saat ini didominasi petugas yang berumur 21-30 tahun, pendidikan SMK/SMA dan S1, rata-rata pengalaman 5-10 tahun, dan status jabatan fungsional terbesar pada tenaga harian lepas. Analisis AHP menunjukkan kinerja petugas dipengaruhi oleh tiga faktor dengan rasio konsistensinya 0,02, yaitu pelaporan dengan bobot prioritas 16%, fasilitas 15,6%, dan pengalaman 13,4%.

Abstract

Albizia (Falcataria moluccana) cultivated in Indonesia for timber plantations can increase the farmer’s income, even though albizia became an invasive alien species that can cause the economic and ecological losses. The controlling of invasive species using biological control is an effective method. The purpose of this study was to determine the phytophagous insects on albizia from Java and Hawaii in seedling in Bogor. The experiment was conducted in Carangpulang, Dramaga, Bogor. The experiment was arranged in a completely randomized block design using seed origin as a treatment (albizia Java and Hawaii) with 4 replicates. Total number of tree sample was 160 trees. Observations were conducted every 2 weeks until 32 weeks after planting. Identification of insects was conducted in the Laboratory of Insect Biosystematics, IPB. A total of 67 phytophagous insects were collected, 57 species in albizia from Java and 54 species in albizia from Hawaii. There was no difference in abundance and diversity of phytophagous insects on albizia from Java and Hawaii. Larvae of Eurema blanda (Lepidoptera: Pieridae) became an important pest causes leaf defoliation. Furthermore, Hulodes caranea (Lepidoptera: Noctuidae), Margarodes sp. (Hemiptera: Margarodidae), Choristoneura sp. (Lepidoptera: Tortricidae), and Adoxophyes sp. (Lepidoptera: Tortricidae) identified as important pests that have not been reported in the other research. Keywords: albizia, defoliator insect, Fabaceae, important pests, invasive alien species

Abstract

The rapid development of oil palm replanting areas will lead to ecological problems such as plant disturbing organisms. Pest and disease attacks are obstacles farmers face when developing their farms, especially in smallholder oil palm plantations. This study aims to examine the components of cultivation techniques, environmental factors, and human resources that influence the application of IPM on smallholder oil palm replanting land in Pangkalan Kuras District, Pelalawan Regency, Riau Province. The methods used in this study included the purposive determination of 60 respondents, data collection through interviews with farmers, field surveys, and data analysis. The results showed that socio-economic aspects influenced farmers' actions in implementing IPM. Farmer knowledge about pests and diseases of oil palm plants was 36%. Farmers have applied several pest and disease control techniques in oil palm cultivation on replanting land. However, most farmers (60%) are still unfamiliar with the term IPM, need to learn the role of natural enemies in pest control in the field, and lack regular monitoring. Keywords: disease, IPM, palm oil, pest, replanting
