Abstract

ABSTRAK Bawang merah (Allium ascalonicum L.) termasuk tanaman hortikultura yang bernilai ekonomis tinggi di Indonesia. Kebutuhan bawang merah terus meningkat, namun hasil produksi dari petani menurun pada musim penghujan (off-season) yang disebabkan fotosintesis tanaman kurang optimal dan serangan hama dan penyakit. Rhizobakteria Pemacu Tumbuh Tanaman (RPTT) yang menghasilkan zat pengatur tumbuh mampu meningkatkan ketahanan tanaman, pertumbuhan dan produksi bawang merah. Penelitian ini bertujuan untuk mengetahui produksi bawang merah pada musim hujan dengan aplikasi RPTT. Penelitian dilakukan di lahan pertanian di Desa Randuagung, Kecamatan Singosari, Kabupaten Malang pada Desember 2017 sampai dengan Februari 2018. Metode penelitian yang digunakan adalah Rancangan Acak Kelompok dengan 2 Faktor. Faktor pertama berupa penambahan Bacillus subtilis (0, 5, 10 ml/l) dan faktor kedua penambahan Pseudomonas fluorescens (0, 5, 10 ml/l) sehingga diperoleh 9 kombinasi perlakuan dengan 3 kali ulangan. Aplikasi dilakukan setiap 7 hari sekali dengan larutan (sesuai perlakuan) 200 ml per tanaman. Parameter pengamatan meliputi tinggi tanaman, jumlah daun, jumlah umbi per tanaman, diameter umbi, berat umbi per tanaman, berat umbi per petak dan produktivitasnya. Hasil penelitian menunjukkan bahwa interaksi perlakuan B. subtillis dan P. fluorescens dapat meningkatkan pertumbuhan dan produksi bawang merah. Hasil produksi bawang merah terbaik berupa berat umbi per petak 3,12 kg diperoleh dari hasil perlakuan B. subtillis 5 ml/l dan P. fluorescens 0 ml/l. Pemberian RPTT dapat menghasilkan bawang merah sesuai dengan potensi varietasnya yaitu 14,16 to ha-1. Peningkatan produksi bawang merah pada musim hujan dapat dilakukan melalui aplikasi RPTT). Kata kunci— bacillus subtillis; bawang merah; produktivitas; pseudomonas fluorescens ABSTRACT Shallots (Allium ascalonicum L.) are horticultural commodities with high economic value in Indonesia. The need for shallots continues to increase, but production yields from farmers decrease in the rainy season (off-season) due to less than optimal plant photosynthesis and pests and diseases. Plant growth-promoting rhizobacteria (PGPR), which produce growth regulators, can increase plant resistance, growth, and yield of shallots. This study aims to determine the production of shallots in the rainy season with the PGPR application. The research was conducted on agricultural land in Randuagung Village, Singosari District, Malang Regency, from December 2017 to February 2018. The research method used was a factorial randomized block design, with the first factor being the addition of Bacillus subtilis (0, 5, 10 ml / l) and factors. The second edition of Pseudomonas fluorescens (0, 5, 10 ml / l) obtained nine treatment combinations with three replications. Applications were carried out every seven days with a solution (according to treatment) of 200 ml per plant. Observation parameters include plant height, number of leaves, tubers per plant, tuber diameter, tuber weight per plant, tuber weight per plot, and productivity. The results showed that the interaction between the treatment of B. subtillis and P. fluorescens could increase the growth and production of shallots. The best yield of shallot in the form of tuber weight of 3.12 kg per plot was obtained from the treatment of B. subtillis 5 ml / l and P. fluorescens 0 ml / l. PGPR can produce shallots according to the potential varieties, namely 14.16 to ha-1. Increasing shallot production during the rainy season can be done through the PGPR application).

Abstract

Bogor Botanic Gardens is an ex-situ plant conservation area in Indonesia. Since BBG is 103 years old, many collections are 100 years old or older. These antique collections may sustain damage, such as broken or collapsing, endangering visitors and employees. As a result, monitoring tree health at BBG is a critical task. According to the tree health monitoring data, 73 of 244 trees were further checked using the PiCUS Sonic Tomograph. Trees from the Fabaceae (31%) and Myrtaceae (10%) families were the most frequently checked. Walnuts trees from the Burseraceae family had the most specimens (47,94%). The PST effectively provides an immediate picture of the stem condition by calculating solid and decaying wood percentage values.
