Corn is one of the important commodities in Indonesia that is not only used as food but also as livestock feed and industry, as well as alternative fuels (biofuels). Degradation of soil fertility became one of the factors limiting the production of this commodity. The purpose of this study was to determine the effect of innovative phosphate fertilizer on the growth and yield of sweet corn on Inceptisols with low fertility. The research was conducted from September 2018 to January 2019. Randomized Block Design (RBD) was used with treatment arrangements as follows: A = Control (without P), B = Recommended NPK dosage (300 kg / ha urea + 150 kg / ha SP-36 + 50 kg / ha K), C = ¼ P (300 kg / ha N + 25 kg / ha SP-36 Inv + 50 kg / ha K), D = 1/2 P (300 kg / ha N + 50 kg / ha SP36 Inv + 50 kg / ha K), E = ¾ P (300 kg / ha N + 75 kg / ha SP-36 Inv + 50 kg / ha K), F = 1 P (300 kg / ha N + 100 kg / ha SP-36 Inv + 50 kg / ha K), G = 1 ¼ P (300 kg / ha N + 125 kg / ha SP-36 Inv + 50 kg / ha K), H = 1½ P (300 kg / ha N + 50 kg / ha SP-36 Inv + 150 kg / ha K), I = 1 ¾ P (300 kg / ha N + 175 kg / ha SP-36 Inv + 50 kg / ha K), J = 0 (Without NPK). The results showed that the SP-36 innovative inorganic fertilizer that was given together with urea and KCl increased the yield of sweet corn equivalent to the standard yield of corn in NPK fertilizer. The treatment with the highest results is 1½ P doses of SP-36 innovation results and P from standard NPK both of which are equivalent to 150 kg / ha P. The yield of sweet corn yields ranges from 21.16 - 21.56 tons per hectare.

Bioremediation of petroleum waste using the land treatment system is generally carried out by indigenous Petrophilic stimulation as a degrading agent. One of the efforts to improve the performance of the bioremediation system is by adding petrophilic inoculants and organic material as a source of nutrition. This experiment focused on observation of the effect of endogenous petrophilic consortium by adding chicken manure compost towards bioremediation performance parameters, including the efficiency of hydrocarbon degradation, soil pH and petrobacter population on Jatinangor Inceptisols contaminated with petroleum waste. The experiment Design used in this experiment was Factorial Randomized Block Design (FRBD). The first factor was the variation of the concentration of the petrophilic consortium, consisted of: (i) without a petrophilic consortium, (ii) the concentration of petrophilic consortium 1% (w/ w), (iii) the concentration of petrophilic consortium 3% (w/ w ), (iv) concentration of petrophilic consortium 5% (w/ w). The second factor was the variation of the concentration of chicken manure compost: (ii) without compost chicken manure, (ii) the concentration of chicken manure compost 1.5% (w / w), and (iii) the concentration of chicken manure compost 3% (w/w). ). The results showed that the treatment of exogenous Petrophilic and chicken manure could not significantly improve the biodegradation efficiency of hydrocarbons, but the Petrophilic additives of 3% (w/ w) could increase the highest Petrophilic population. From this study was found that indigenous petrophilic had the potential to degrade hydrocarbons by 71.20%, while the application of exogenous 1% (w/w) petrophilic was able to degrade hydrocarbons by 71.97 %.

Acid mine drainage (AMD) is one of the important issues in the environmental damage caused by coal mining activity. Remediation of AMD could be done by active and passive method. Passive method is cheaper and more efficient. Constructed wetland is one of passive method in AMD remediation. The objective of this research was to determine the effect of organic matter and sulphate reducing bacteria (SRB) combination to Fe and Mn concentration in water and substrate. The research used experimental design of Randomized Block Design (RBD) consisted of nine treatments and repeated three times. The result of this research showed that sulphate reducing bacteria and kind of organic matter combination significantly affected water pH, concentration of soluble Mn, and concentration of Fe and Mn in the substrate. Application of 100 % compost and SRB inoculation gave the best increase of water pH. Application 100 % sawdust with SRB inoculation provided the lowest concentration of soluble Fe in outlet water. Meanwhile, 100% sawdust application without inoculation of SRB increased of Mn soluble concentration in outlet water.

The growth and yield of rice plants is very dependent on nitrogen (N) fertilizer. N fertilizer applied to wetland rice mostly unutilized due to the lost through the process of denitrification and leaching. The presence of blue-green algae (BGA), procaryotic algae N2-fixing in the paddy field is advantageous to help to uptake the N for plants by direct fixation of N2 from air and then converted into cell proteins. Excess N fixation results were released into the BGA growth environment. BGA biomass at the latter stage will be mineralized to ammonium. Mineralized ammonium from BGA cells as a source of N that can be used directly by paddy plants. This experiment used a randomized block design with factorial pattern; BGA inoculant dose treatment consisted of: 0; 5 kg; 10 kg ha-1 and urea dose 30; 60; 90; 120 kg N ha-1. The results of this experiment showed that the use of BGA can increase the rate of growth of rice plants and reduced urea requirements by 25%. The combination of 90 kg ha-1 N fertilizer with 10 kg ha-1 Blue-green algae inoculant can increase grain yield by 31.47% per hectare (2.71 tons ha-1).

Analysis of the farming system is an applied science which concerns on how to use resources efficiently and effectively in agricultural business in order to get maximum results. In this analysis, one of the important aspects on agricultural production is fertilizer. Liquid compound fertilizer is a fertilizer with several advantages such as simple application, complete and balanced required nutrients, labour and time efficient, and easy to procure and store. The purpose of this study was to determine the analysis of farming system on the application of liquid compound fertilizer on sweet corn. This experiment used a Randomized Block Design (RBD) consisted of 10 treatments (8 treatments of liquid fertilizer doses, one treatment of fertilizer dosage recommendations for NPK and one control (without fertilizer)). Each treatment was repeated three times, with the total of 30 experimental plots. The results of this experiment were the application of compound liquid fertilizer provides a high relative value of agronomic efficiency and profits on corn. The treatment of 1 ¼ NPK liquid fertilizer dose gave higher RAE, R/C and B/C values compared to the control. NPK liquid fertilizer has a significant effect on the variables of soil (pH, N, P and K content) and yield components (N, P and K uptake). In general, the use of NPK liquid fertilizer can significantly increase the yield, with the highest yield on 1 ¾ dose and the yield of corn plants (18,329 kg/ha).
