Azotobacter sp. is a non-symbiotic bacteria that has the ability to mobilize nitrogen from a form that is not available in a form that is available for plants. Inoculation of Azotobacter sp. into the planting medium can be used as a supplier of nitrogen required by the plant. Utilization of Azotobacter sp. as biofertilizer has the ability to minimize the use of chemical fertilizers, improve the soil fertility and increase the microbial activity in the rhizosphere of plants. Inoculation of Azotobacter sp. into the planting medium is one alternative to improve the efficiency of urea fertilizer in the maize cultivation. The result of this research showed that the application of Azotobacter sp. with the dose of 10 ml l-1 and 20 ml l-1 on the urea fertilization with the dose of 150 kg ha-1 were able to increase the growth of maize, so that maize has growth that was not significantly different with the maize that got urea with the dose of 225 kg ha-1 and 300 kg ha-1. Inoculation of Azotobacter sp. in the planting media, either with the dose of 10 ml l-1or 20 ml l-1were able to increase the maize yield when compared to the treatment without Azotobacter sp. Inoculation of Azotobacter sp. into the planting medium was able to increase the maize yield. However, increasing the dose of Azotobacter sp. more than 10 ml l-1 did not affect to increase the maize yield. Maize yield reached the optimum value when the dose of urea supplied was153.50 kg ha-1.

The aims of this research is to find out the influence of the application of sago waste compost and PGPR on the increase in groundnut growth and yield and to obtain the dose of sago waste compost and PGPR concentration that able to increase the growth and yield of groundnut had been conducted in January to March 2016 in Maba Sangaji Village, Kota Maba Subdistrict, East Halmahera Regency. The research used factorial randomized complete block design consisting of two factors with three replication. Factor I was the dose of sago waste compost consisted of four levels: K0 = without sago waste compost (control), K1 = sago waste compost of 10 t ha-1, K2 = sago waste compost of 15 t ha-1, and K3 = sago waste compost of 20 t ha-1. Factor II was concentration of Plant Growth Promoting Rhizobacteria (PGPR) consisted of 4 levels: P0 = without PGPR (control), P1 = PGPR of 5 ml l-1, P2 = PGPR of 10 ml l-1, and P3 = PGPR of 15 ml l-1. The observation consisted of growth components of plant height, the number of leaves, leaf area, crop dry weight, and crop growth rate, and yield components of the number of pods, filled pods, empty pods, pod weight, grain weight, and weight of 100 grain. Research result shows that there was no interaction between the treatment of sago waste compost and PGPR. However, separately, treatments of sago waste compost and PGPR had the significant influence on the growth and yield of groundnut. The highest groundnut yield was obtained in the treatment of sago waste compost with the dose of 20 t ha-1. Grain weight obtained was 17.51 g or an increase of 52.15% compared to those of treatment without application of sago waste compost and yield of grain weight per hectare was 2.80 t ha-1. The inoculation of PGPR increased the growth and yield of groundnut. The application of PGPR with the concentration of 10 and 15 ml-1 produced better crop growth. The higher result was obtained in the treatment of PGPR with the concentration of 10 and 15 ml l-1with grain weight of 15.46 g and 16.81 g plant-1 or an increase of 31.15% and 42.6%, respectively, compared to control,whereas, grain weight per hectare was 2.47 t ha-1 and 2.69 t ha-1, respectively.

Inceptisol is one type of land order that is widely spread in Indonesia. Its distribution reaches approximately 52.0 million hectares (Kasno, 2009). Inceptisol is widely used as an intensive farm because its management is less precise, then most Inceptisol fertility rate becomes low. This is often shown by soil acidity, organic matter content, and low nitrogen, to improve such properties one of which can use the addition of organic matter. The problem that often arises is the high cost of organic fertilizer. Seaweed industry waste is a source of organic material that has not been widely utilized. Of the total raw materials processed, there is 65 to 70 percent of industrial products produced by the seaweed industry waste every day (Mandela. 2010). Usually these side products are only left to accumulate at the landfill site. Seaweed industry waste has the potential to be used as a source of soil organic matter because the organic material content of products of seaweed industry reaches 6.4% (Afif, 2011). The addition of nutrients to the application of inorganic materials is considered as an alternative step in increasing crop productivity. Based on the description above, it is necessary to conduct research to utilize the waste of seaweed industry, to get high corn production in Inceptisol. The objectives of this research are: (1) To know the effect of seaweed industrial solid waste on soil chemical properties Inceptisol and (2) growth of maize. The research was conducted in the greenhouse, while for the analysis of soil samples and the waste of seaweed industry was conducted in soil chemistry and soil physics laboratory, Department of Soil Science, Faculty of Agriculture, Brawijaya Universities. The study was conducted from May to August 2016. The soil samples used in this study were taken from Kemirisewu village, Pandaan sub-district, Pasuruan district at a depth of 0-20 cm. The waste of seaweed gel plant is obtained from PT. HAKIKI DONARTA, Pandaan Sub-district, Pasuruan Regency. The basic fertilizers used are Urea, KCl, and TSP. Maize seeds used as indicator plants are hybrid varieties of BISI-2 maize. This study used Completely Randomized Design (RAL) with 4 (four) treatments and 3 (three) replications. Addition of solid waste of seaweed with the dosage of 15 Mg/ha, increased of soil acidity and C-Organic content, besides also can increase Phosphorus and Potassium content available, Nitrogen, Phosphorus, and Potassium plant uptake, and the best growth of maize.
