Abstract

Around the Dua Island area is a fertile rice field area, many flocks of egrets are found in the rice fields looking for food. The existence of the buffalo egret (Bubulcus ibis) as a natural predator in eradicating plant pests, is also an important component in the wetland ecosystem. This study aims to determine farmers' perceptions of the function and existence of the buffalo egret (Bubulcus ibis) and analyze the factors that influence farmers' perceptions of the buffalo egret (Bubulcus ibis) in the Pulau Dua Nature Reserve, Banten Bay. Methods of data analysis using tabulations to describe the factors that influence the perceptions and perceptions of farmers, while analysis of canonical correlation to determine the relationship between perceptions with the factors that influence farmer's perceptions. The results showed that most of the farmer respondents had a low level of education, control over land area and limited information sources and did not participate in farmer groups, however, their understanding of the function and existence of the buffalo egret (Bubulcus ibis) was very good. While the canonical correlation results show that farmers' perceptions of egrets are influenced by gender, age, status in the family, level of education, land area, participation in farmer groups and sources of information. Of the seven variables, there are two of the strongest variables, namely age and level of education.

Abstract

Jati Unggul Nusantara (JUN) (Tectona grandis L.f.) banyak diminati karena memiliki masa panen yang singkat. Dibalik keunggulan itu JUN memiliki sifat kayu yang kurang stabil. Kondisi tersebut dapat diperparah oleh serangan hama dan penyakit yang bersumber dari vegetasi yang telah ada sebelumnya. Sisa vegetasi di suatu pertanaman dapat menjadi penghubung bagi siklus kehidupan hama dan penyakit. Di kebun percobaan Universitas Nusa Bangsa (UNB) terdapat tunggul JUN yang dibiarkan tumbuh menjadi tegakan baru (terubusan). Tujuan dari penelitian ini adalah menginventarisasi hama dan penyakit pada daun terubusan JUN melalui pengamatan gejala kerusakan daun. Penelitian ini dilakukan pada bulan April – Juli 2021 di Kebun Percobaan UNB, Desa Cogreg, Kabupaten Bogor. Sampel pohon ditentukan dengan metode transek sepanjang 160 m. Pengamatan sampel daun dilakukan dengan cara dipetik kemudian diamati jenis dan luas tutupan gejalanya. Luas tutupan kerusakan pada daun tersebut diamati dengan bantuan bidang ukur berbahan mika plastik berukuran 20 x 20 cm. Hasil penelitian menujukkan 666 (86%) helai daun bergejala serangan hama dan/atau penyakit. Sebagian besar kerusakan ditimbulkan oleh penyakit daripada hama. Serangan penyakit yang ditemukan antara lain hawar, shot-hole, karat, embun tepung, karat, dan klorosis. Adapaun gejela serangan hama yang ditemukan yaitu defoliasi, leaf-miner, skeletonize, dan lekukan. Gejala hawar, shot-hole, dan defoliasi merupakan gejala yang paling sering ditemukan. Sementara itu, nilai keparahan tertinggi didapatkan pada gejala embun tepung, hawar, dan karat daun.

Abstract

The leaves of Dioscorea bulbifera L. have chemical compounds that have the potential as bioinsecticides. This study aims to determine the effectiveness of polar, semi-polar, and non-polar fractions in D. bulbifera leaf extract as bioinsecticides. The research design used was a Factorial, Completely Randomized Design consisting of two factors with five repetitions using the contact method against Cryptotermes cynocephalus. The first factor was the type of solvent: non-polar solvents, semi-polar solvents, and polar solvents. The second factor was concentration, with a range of 5%, 4%, 3%, 2%, and 1%. Based on the results, the D. bulbifera leaves in the polar fraction contain alkaloids, flavonoids, phenols, triterpenoids, and saponins. The semi-polar fraction contains alkaloids, phenols, and steroids. The non-polar fraction contains alkaloids, phenols, and triterpenoids. GC-MS identification showed 20 metabolite compounds as potential as botanical insecticides. The highest termite mortality was in the non-polar fraction, with a 4% concentration of 32.80% (equivalent to a corrected mortality of 27.58%). The semi-polar fraction (3.20 g and 15.10%) at a concentration of 5% (2.58 g and 12.19%), showed the best reduction in test weight and degree of damage. This result indicates that D. bulbifera is an effective bioinsecticide in the repellent group.
