The Inceptisol of Karangploso Malang has low pH (5.33) and low C-organic content (1.39%). Efforts can be made to improve these problems through land management with the use of organic fertilizer. Bokashi is one of the composts produced from fermentation process with EM4 which can improve soil chemical properties, because bokashi has elements of N, P, K, Na, Ca, and Mg respectively 1.22%, 0.53%, 1.71%, 5.64%, 0.62% and 2.01%. This study was carried out at the Greenhouse and Chemical Laboratory of Soil Science Department, Agriculture Faculty, Brawijaya University. The design of this research was a completely randomized design with O0 treatment (control); O1 (Bokashi 5 t ha-1); O2 (Bokashi 10 t ha-1); O3 (Bokashi 15 t ha-1); O4 (Bokashi 20 t ha-1); O5 (Bokashi 25 t ha-1); O6 (Bokashi 30 t ha-1) which was repeated 3 times. Parameters measured were pH, CEC, BS, K-exch, Na-exch, Ca-exch, and Mg-exch on 1 MAI (month after incubation), and 2 MAI. The results showed thatÂ increasing the dose of bokashi application at 1 MAI significantly increased K-exch and Mg-exch compared to the control treatment, but did not significantly affect pH, CEC, BS, Na-exch, and Ca-exch. Furthermore, increasing the dose of bokashi application on 2 MAI significantly increased pH and K-exch compared to the control treatment, but did not significantly affect CEC, BS, Na-exch, Ca-exch, and Mg-exch.

Soil contains many elements, both macro, micro and metal. Metal elements are generally non-essential. Cobalt (Co) is one of the metallic elements but required in very small amounts for life. At high concentrations of cobalt can cause poisoning. One way to reduce high levels of cobalt in the soil by performing bioremediation plus ameliorant materials. This study consists of two stages. The first stage is the pot scale research with factorial design. The first factor is the bioremediator dose, namely : B0 : Without bioremediator (control), B1 : Bioremediator 20 kg ha-1, B2 : Bioremediator 50 kg ha-1 and the second factor is the application of ameliorant materials, namely: A0 : No ameliorant (control), A1: Biochar + compost (1: 5), A2 : Biochar + compost (2: 5), A3 : Activated charcoal + compost (1 : 5), A4 : Activated charcoal + compost (2 : 5). The second stage is the four best results from the first stage applied in situ on the lysimeter. The results showed that the treatment of bioremediator with a dose of 20 kg ha-1 and activated charcoal + compost (w: w = 2: 5) was able to reduce Co levels in the soil by 76%. The lowest Co level in rice that is equal to 3.06 mg kg-1 was obtained from the treatment of 50 kg bioremediator ha-1 plus active charcoal + compost ameliorant (1: 5).Â

Biofertilizer applications are needed to improve soil quality such as soil productivity and increasing the efficiency of the fertilization. Availability of nutrients in the soil is affected by microbes found in the soil. Soil microbes reproduce themselves and active in supplying nutrients to plants by releasing nutrients that are bound to be available to plants. The aim of this research was to observe and analyze the effect of biofertilizer on sugarcane growth and its effect on the population of potassium solubilizing bacteria. Results showed that The application of basic fertilizer combined with biofertilizer has a significant effect on the growth of sugarcane both in plant height and diameter of the stem. In the parameters of plant height, the best treatment was A5 which was a combination of anorganic fertilizer + 200% biofertilizer same as the other plant growth parameter which was stem diameter. Then on the production parameters, fresh plant weight and root weight, best treatment was A5. As for the parameters of potassium solubilizing bacteria, the best treatment that increased population was treatment A4 which was basic fertilizer combined with 150% biofertilizers. In total soil bacteria, the various application doses of biofertilizers did not have a significant effect. However, there was an increase of 0,49% in treatment A5 (basic fertilizer+200% biological fertilizer) compared to control (A1). The application of biofertilizer also did not have a significant effect on the parameters of organic matter and soil water content
