Abstract

Tujuan penelitian untuk mengetahui jenis-jenis mikroba yang terdapat pada rhizosfer tanaman lada Malonan 1 di Kecamatan Muara Badak Kabupaten Kutai Kartanegara. Penelitian dilaksanakan sejak bulan  Juli sampai Agustus 2018, di Laboratorium Hama dan Penyakit Tanaman Fakultas Pertanian Universitas Mulawarman Samarinda.Hasil penelitian diperoleh bahwa mikroba rhizosfer pada tanaman lada teridentifikasi 1 isolat bakteri, 3 isolat fungi dan 3 isolat nematoda. Bakteri terdiri dari 1 Famili yaitu Azotobacteraceae. Fungi meliputi 3 genus yaitu Aspergilus, Colelotrichum dan Trichoderma. Sedangkan nematoda meliputi 3 genus yaitu Dorylaymus, Paratylenchus dan Rhabditis. Jenis-jenis mikroba yang bermanfaat bagi ekosistem tanah meliputi bakteri  Azotobacteraceae yang dapat menambat N2 (fiksasi) N2 atau biofertilizer. Fungi  Aspergillus dan Trichoderma berperan sebagai agen hayati atau menghambat pertumbuhan patogen (biokontrol) untuk mengendalikan penyakit tanaman. Sedangkan nematoda Dorylaymus, Paratylenchus dan Rhabditis merupakan mikroba perombak atau decomposer.

Abstract

Penyerapan dan ketersediaan unsur hara dapat ditingkatkan dengan adanya mikroorganisme tanah.. Lahan perkebunan kelapa sawit umumnya diusahakan pada lahan marjinal dan keragaman populasi mikroba tanah yang rendah. Tujuan penelitian untuk mengidentifikasi mikroba agens hayati pada lahan kelapa sawit belum menghasilkan di Kecamatan Marang Kayu, Kutai Kartanegara. Pengambilan sampel tanah berlokasi di perkebunan kelapa sawit belum menghasilkan milik rakyat di Kecamatan Marang Kayu, Kutai Kartanegara dan proses identifikasi (penghitungan dan isolasi) mikroorganisme di Laboratorium Hama dan Penyakit Tanaman Fakultas Pertanian Universitas Mulawarman. Metode penelitian ini meliputi dua metode meliputi penghitungan jumlah mikroorganisme tanah dan isolasi mikroorganisme tanah. Hasil penelitian menunjukkan mikroba yang terdapat pada lahan kelapa sawit belum menghasilkan yang berpotensi sebagai agens hayati yaitu jamur Trichoderma.

Abstract

One of the obstacles in increasing and stabilizing crop production is the onslaught of soil pathogens that causes damage to plants and decreases the quantity and quality of production. This study aims to identify and determine the population of rhizosphere microorganisms in rambutan plants. The research was conducted at Plant Pest and Disease Laboratory of Agricultural Faculty of Mulawarman University of Samarinda from July to August 2016. This research uses exploration method with observation technique which is done by growing microorganism in media so that for 5 days then calculate growth rate of each microorganism. The data obtained were analyzed using quantitative descriptive analysis. Based on the result of the research, it can be concluded that the results of isolation of micorganism from rhizosphere rambutan plant obtained 3 isolates include: 1 isolate bacteria from Azotobacteraceae Family and 2 isolates of fungi from genus Aspergilus and Phytium genus. Of the 3 types of isolates, 2 types of microorganisms are included into microorganisms that are beneficial to soil ecosystems that include the Azotobacteraceae Family that play a role in the fixation (fixation) N2 (biofertilizer) and Aspergillus Genus that act as a potential pathogen growth inhibitor (bio control) diseases in plants while the Phytium Genus is a pathogenic fungus (the cause of disease) that can affect the low production of plants.

Abstract

The Influence of NPK Phoska Fertilizer and Liquid Organic Fertilizer on Banana Plant Growth and Production (Musa sp). The purpose of this study was to determine the effect of NPK Phoska fertilizer and liquid organic fertilizer on the growth and production of banana rutai plant. The study was conducted for 7 (seven) months, from February to September 2015, starting from land preparation to data collection. This research was conducted on campus of Widya Gama Mahakam Samarinda. The research design used was factorial randomized block design 3 x 3 with 3 times replication. The first factor was Phoska NPK fertilizer (P) consisting of 3 levels: P0 (Without Treatment), P1 (1080 g / plant) and P2 (1580 g / plant). The second factor is the application of liquid organic fertilizer (B) 3 levels, namely: B0 (Without treatment), B1 (5000 ml) and B2 (10000 ml). The result of the research showed that the best treatment of NPK Phoska P2 (1580 g / plant) was the average of plant height 90 days after the highest treatment was 122.33 cm, the largest mean stem diameter was 11,08 cm and average the highest number of comb per bunches is 7.22 comb, the fastest harvest age is 248 days after planting. The best treatment of liquid organic fertilizer to the average number of combs per cluster was achieved at the treatment of B1 (5000 ml) ie 5.33 comb, the fastest harvest age 248 days after planting. The interaction between NPK Phoska fertilizer application and liquid organic fertilizer did not significantly affect all observation parameters.
