dc.description.abstract | Gangguan seperti kegiatan pertambangan batu bara dapat mengurangi populasi mikroba di rhizosfer. Penelitian ini bertujuan menganalisis pengaruh pemberian berbagai dosis amelioran tanah serta Al dan Fe terhadap bakteri rhizosfer dan populasi Fungi Mikoriza Arbuskula (FMA) pada bibit sengon laut (Paraserianthes falcataria (L.) Nielsen) di media pascatambang batu bara. Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap dengan petak terbagi yang terdiri dari tiga perlakuan, yakni pemberian FMA, amelioran tanah (kompos, kapur, dan faba), serta dosis Al dan Fe. Hasil penelitian menunjukkan pengaruh tunggal pemberian FMA dan penambahan amelioran tanah dengan komposisi kapur 5% dan kompos 0,5% mendukung perkembangan bakteri pada rhizosfer bibit P. falcataria dengan rata-rata jumlah koloni sebesar 168 CFU/g sedangkan pemberian konsentrasi logam Al dan Fe dapat menekan perkembangan bakteri. Terdapat sembilan karakteristik morfologi koloni bakteri yang berbeda dilihat dari bentuk, tepi, elevasi, dan warna koloni. Koloni bakteri terbanyak ditemukan dengan karaktertistik round, entire, convex, dan berwarna putih. | id |
dc.description.abstract | Disturbances such as coal mining activities will reduce the microbial population around the rhizosphere. This study aims to analyze the effects of various doses of soil ameliorant and metals (Al and Fe) to the rhizosphere bacteria and the population of Arbuscular Mycorrhizal Fungi (AMF) in Sengon Laut (Paraserianthes Falcataria (L.) Nielsen) seedlings using post-coal mining media. The experimental design used for this research was split plot design in a completely randomized design consist of three factors which are inoculation of AMF, soil ameliorant, and various doses of Al and Fe. The results showed single treatment of AMF inoculation and soil ameliorants with 0,5% lime and 5% compost support the growth of bacteria in the rhizosphere of P. falcataria seedlings with 168 CFU/g while the concentration of Al and Fe restrain the growth of bacteria. There were nine different morphological characteristics of bacterial colonies seen from the shape, margins, elevation, and colony color. The colony characteristic mostly found in this study is round, entire, convex, and white. | id |
