Abstract

Tungau merah ( Panonychus citri McGregor) adalah salah satu hama tanaman yang menyerang daun jeruk. Biasanya, petani mengendalikan hama menggunakan pestisida kimia dan menyebabkan kerusakan lingkungan karena racun yang terkandung dalam bahan pestisida. Pestisida kimia juga menghasilkan peningkatan resistensi hama terhadap pestisida. Pestisida persisten juga meninggalkan residu yang sulit dibersihkan pada tanaman sehingga pestisida alami diperlukan sebagai alternatif pestisida kimia. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh konsentrasi pestisida nabati daun sirsak ( Annona muricata ), daun pepaya ( Carica papaya ), Krisanmembuat kematian hama merah dan pestisida nabati tetap ada. Hasil penelitian menunjukkan bahwa konsentrasi pestisida 5% menghasilkan 100% mortalitas fase imago dan instar fase 1 pada 48 jam pengamatan. Angka kematian tertinggi adalah perlakuan pestisida daun pepaya konsentrasi 5% pada fase imago yaitu sejumlah 29,67

Abstract

Glutinous rice corn crops in Java show low productivity despite their potential. Agricultural land issues in Indonesia, such as soil fertility and excessive use of inorganic fertilizers, persist. Tithonia diversifolia plants are utilized for composting to address these concerns. Additionally, corn root microorganisms act as biological fertilizer, enhancing plant growth. This study aims to investigate the interaction between Tithonia compost dosage and corn root Rhizobacteria on glutinous corn growth and yield. Conducted in two locations—laboratory for Rhizobacteria isolates and field for composting and planting—the research employed a Divided Plot Design with 36 treatment combinations. Observations included plant height, stem diameter, leaf area, cob count, cob diameter, cob weight, and cob length. Results indicate interaction effects between Rhizobacteria and compost dosage on leaf area growth at 28 days post-planting. Additionally, there's an impact on stem blight intensity at 42 days post-planting. Rhizobacteria dosage didn't significantly affect plant growth or cob yield parameters. However, paitan compost dosage influenced plant height, stem diameter, and cob count, with the best response seen at 14 tons/ha dosage.

Abstract

Need oil fuel in Indonesia has increased. Oil production reached only 410,000 barrels per day while the needs of up to 1 million barrels per day. One plant is capable of producing biofuels is Pecan sunan. Vegetative reproduction has been hampered by the limited number of obtained so that necessary research in vitro. This research aims to know the concentration of the substance growing balance sitokinin (BA, TDZ and kinetin) and Auxin (NAA) in Pecan sunan buds induces on the MS medium. Experimental design used was Complete Random Design simple. The treatment is the composition of the basic MS medium with medium that is combined with the astringent balance grow NAA (0.5 mg/l), BA (1-3 mg/l), TDZ (0.2 mg/l) and kinetin (2 mg/l). The result of the observation form buds, but callus changes color and size kalus. Before and after color callus subculture of potentially forming buds is the A9 (MS + 0.5 mg/l NAA + 3 mg/l BA + 2 mg/l kinetin). While kalus response tends to be good on the A5 is 0 MS media (MS + 0.5 mg/l NAA + 2 mg/l BA + 0.2 mg/l TDZ) and G media is A2 (MS + 0.5 mg/l NAA + 2 mg/l BA).
