“…However, based on the observations, the concentration of the IAA hormone that KSB1 produced (57 ppm) was slightly higher than the other isolates. According to a study by Pambudi et al (2017), the highest IAA con-centration was found in TGR 2.17 bacteria from rice field soil which was 0.116 ppm. The results obtained from that study was very low.…”

Endophytic bacteria are microorganisms that thrive in plant tissue without causing any negative effects to the host plants. The purpose of this study was to apply endophytic bacteria that have the potential to produce IAA hormones as biological agents in rice seeds. This research was conducted by testing IAA hormone using a spectrophotometer, testing HCN production using filter paper, biochemically identification of the isolate, and applicating endophytic bacteria into rice seeds. Endophytic bacteria have different abilities in producing IAA hormone. Based on the results of the study, the highest IAA concentration (57 ppm) was obtained from KSB1 (Potassium Solubilizing Bacteria) isolates and followed by KSB3 isolate with 56 ppm. All the endophytic bacteria isolates were unable to produce HCN. Results of the study showed that KSB1 and KSB3 isolate were able to influence the growth of root length by 5.62 cm and 6.70 respectively as well as the canopy height by 8.56 cm and 8.30 cm respectively. Based on observations of colony morphology, cell morphology and biochemical tests, KSB1 was presumably belong to the genus Staphylococcus. In this study, new information about endophytic bacteria that can increase the growth of Ciherang variety rice can be obtained. This study provides information that the application of environmentally friendly bacteria is important to preserve the environment and agriculture sustainability in Indonesia without reducing the productivity of rice.

“…Hasil dari ke-11 isolat BPF memiliki kesamaan yang merupakan bakteri dengan sifat kimia Katalase Positif. Hal ini sesuai dengan pernyataan Mukamto et al, (2015), Pambudi et al, (2017) dan juga Oksana et al, (2020) bahwa BPF merupakan bakteri yang dikelompokkan dalam Katalase positif. Isolat BPF yang memiliki sifat kimia Katalase positif ditandai dengan adanya gelembunggelembung udara hasil dari reaksi H2O2 3%.…”

Ketersediaan unsur fosfat dalam tanah yang rendah disebabkan karena terikat oleh koloid tanah. Tanah yang memiliki pH asam maka fosfat akan diikat oleh unsur seperti Al, Fe sedangkan tanah yang memiliki pH basa maka akan diikat oleh unsur Ca. Upaya yang dilakukan untuk mengatasi rendahnya unsur fosfat yang tersedia di dalam tanah adalah dengan memanfaatkan Bakteri Perlaut Fosfat (BPF), karena mikroba tersebut merupakan jasad renik tanah yang memiliki kemampuan melepaskan ikatan fosfat dan berperan penting dalam melarutkan unsur fosfat yang tidak tersedia menjadi tersedia. Tujuan pertama dari penelitian ini adalah untuk mengisolasi BPF dan untuk mengidentifikasi BPF yang dapat digunakan sebagai agens hayati untuk mendukung konservasi tanah. Dan tujuan kedua dari penelitian ini adalah untuk mengetahui kelimpahan koloni BPF. Metode yang digunakan yaitu menggunakan pengujian secara makroskopis dan biokimia. Analisis yang digunakan adalah menggunakan deskriptif kuantitatif. Koloni paling banyak ditemukan yaitu pada kode sampel HP-1-D dengan jumlah koloni 266 x 104 cfu/μl dan paling sedikit yaitu pada kode sampel HP-2-B dengan jumlah isolat 6 x 104 cfu/μl. Jenis genus Bakteri Pelarut Fosfat (BPF) yang berhasil di identifikasi pada Hutan Produksi di KHDTK Pujon Hill UMM diantaranya yaitu genus Micrococcus sp dan Bacillus sp yang memiliki sifat yaitu gram positif dan katalase positif.

Nitrogen makes up about 78% of all the gases in the atmosphere. Although it is very abundant in the atmosphere, nitrogen cannot be used directly by plants. The aims of this study were to isolate, characterize and identify the morphology and physiology of methanotrophic bacteria, calculate the total population of methanotrophic bacteria and analyze the chemical properties of paddy rice soil in Morowali Regency. Results Based on the gram reaction test, 11 isolates were gram negative, 11 isolates were catalase positive, 11 isolates were capable of nitrogen fixation, five isolates were yellowish white, five isolates were white, one isolate was yellow, six isolates had a convex elevation, and five isolates had a flat elevation. Based on the identification results, the Witaponda sub-district produced five isolates, three isolates from Bumiraya, two isolates from Bungku Barat and one isolate from Bungku Tengah District. Based on the results of the calculation of the number of bacteria found in Witaponda subdistrict as much as 54.05x106 Cfu/mL Bumiraya as much as 40.21x106 Cfu/mL, Bungku Barat as much as 12.06x106 Cfu/mL, Bungku Tengah as much as 11.65x106 Cfu/mL. The results of the analysis of soil chemical properties showed that pH, CEC, organic C, P205, K were classified as low in both irrigated and rainfed rice fields.
