Abstract

The constrains of corn cultivation on Entisol is due to the low nutrient absorption, one of this element is Nitrogen. The reason is Nitrogen can easily for leached from the soil in the form of nitrate (N-NO3-), and will volatilized into the air in the form of ammonia gas (NH3) or left in the ground so it can't be absorbed by plants. One effort that can be done to address the problems of  Entisol is with the addition of organic matter as well as a balance fertilizer. Organic ingredients are used in the research is mixed with humic acid with urea. This study was aimed to examine the influence of application of urea-humate dosage on N availability and uptake of N of corn. The results showed a significant effect of application of urea-humate to NH4+ and NO3- at 30 DAI. The urea-humic acid could improve soil pH, soil CEC, plant height, and total dry weight. Correlation between soil N-available level with uptake of N level was significant at p = 0,05 (r = 0,81). Urea humate 125% has the highest increase of 49,32% on N-uptake of corn compared with the treatment of urea

Abstract

Inceptisols is one among many ordos which distribution is quite wide in Indonesia. Based on data from the Agency for Agricultural Research and Development (2000) with low to moderate organic matter content. As the organic matter content is low enough, the addition of organic matter is needed. Organic materials needed, can be used for fertilizers. Fertilizers used may be organic or inorganic fertilizers. The aim of this study is to learn about the effect of treatment mucus earthworm to nutrients contained in the Inceptisol soil. The purpose of the study is to determine the effect of fermented liquid earthworm (Lumbricus rubellus) manure to increased phosphorus nutrients available in the Inceptisol soil and add available phosphorus nutrients in the Inceptisol soil. With the hypothesis of increasing the dose liquid earthworm (Lumbricus rubellus) manure fermentation can increase levels of available phosphorus in the Inceptisol soil. The benefits of this research is a fermented earthworm (Lumbricus rubellus) liquid organic fertilizer can add available  phosphorus nutrients to the Inseptisols soil. This research was conducted in the greenhouse of the Faculty of Agriculture, University of Brawijaya, while liquid fertilizer process conducted in Sidoarjo Mr. Subchan house. Basic analysis of the soil was conducted in the laboratory of Chemistry, Department of Chemistry, Mathematics Faculty, University of Brawijaya. This research was conducted from March to May 2016. Based on our research of liquid mucus earthworms fertilizer may improve available phosphorus nutrient, pH and C-organic with the highest increase incubation for 4 weeks at P3 doses treatment with 100mL / L of water. The more number of liquid earthworm mucus fertilizer on the Inceptisols soil, the more the increase in the available phosphorus nutrients, pH and C-organic in the Inceptisols soil.

Abstract

Pujon is one area in East Java province, which often landslides. Relief hilly to mountainous with steep slope to steep and high rainfall intensity causes landslides. Given the magnitude of the threat of landslides, it is necessary to study the estimation of landslide area by utilizing the limited data, especially the area around the transport path. Information about potential landslide hazard map is indeed very good, but often encountered problems in preparation for recording at least a landslide. This problem can be solved by a method called Analytic Hierarchy Process (AHP). This method can be used when there is limited quantitative data. The research was conducted in the Kalikonto watershed, Malang, East Java Province. The results showed that Pujon can be grouped into four classes of landslide susceptibility, namely: not vulnerable, somewhat vulnerable, vulnerable and very vulnerable. The area is not vulnerable area of 9,770 ha, or 64.05% of the total area, somewhat vulnerable area of 4.9001 ha or 30.82%, vulnerable of 768 ha or 5.03% and the area is very vulnerable of 14.85 ha or 0.1 %. The factors that most influence susceptibility to landslides in Pujon is a slope with a score of 45% weight of all parameters. However, the assessment of AHP in Pujon not fully applicable. Estimation of the potential hazard of landslides manually generate distribution maps of landslides are quite accurate, but the use of expert choice could not be applied.

Abstract

Mining activities have an impact on the ground in the form of a high content of heavy metals, soil density increased due to the use of heavy equipment, a process of reversal and mixing top soil and sub soil, as well as poor aeration and drainage. One way to do PT Bukit Asam (Persero) to overcome it by doing reclamation using Cajuputi plant (Melaleuca cajuputi). Cajuputi plants have a high level of adaptation can improve soil physical properties such as texture, porosity, saturated hydraulic conductivity, moisture content, bulk density, specific gravity, pH and C-Organic. This study was conducted to determine the effect on the development of reclaimed land in the physical properties at area coal post mining and determine the effect of age Cajuputi reclamation plant (Melaleuca cajuputi) to changes in the physical properties of the soil. On the difference in age of the plant 1 year, 3 years and 5 years, and there are 5 replicates. Texture has increased in the sand at 19.3%, porosity and saturated hydraulic conductivity increases proportional to the levels of C-organic soil. Bulk density and density decreased. Value acidity decreased, but no real effect on the t test between the age of the plant reclamation. The decline also occurred at the level of the water content caused increasing age of root crops will be easier to absorb water in field capacity and the addition of organic matter to add the activity of organisms in the soil and plant litter to protect ground water from direct blows.

Abstract

The increasing of rice productivity which followed by environmental sustainability and land’s fertility can be done by using of biological fertilizers. There is a type of microbes that are potentially as biological fertilizers which can be utilized as a supplier of rice crops’ nutrient and it has a plentiful number is Cyanobacteria. Cyanobacteria or blue-geen algae includes into one of prokaryotic algae goup. This organism roles as manufacturer and producer of nitrogen compound (N) in the water. This research was carried out in the greenhouse Balai Penelitian Tanah, Bogor from November 2016 to April 2017. The experiment was designed using Randomized Block Design with 2 Factorial factors. The first factor is isolates Cyanobacteria (Control, KL2’ isolate and C37’s isolate with dose 250 kg ha-1) and the second factor is the nitrogen fertilization (0%, 25%, 50%, 75% and 100% of the recommended dose from 250 kg Urea ha-1) which is repeated three times. The result showed that different doses of nitrogen fertilization gave an effect on the population of Cyanobacteria. Treatment of S1N1 has a higher total population as 333,33 cfu g-1. Giving Cyanobacteria tends to decrease the total N residue of the soil and followed by increased yield of rice. S0N3 treatment has the highest containing of N as 0,23%. The interaction of  application Cyanobacteria and different doses of nitrogen fertilization not give a real effect to the growth and yield of rice.. Giving Cyanobacteria does not give a real effect on all parameters of observation. Nitrogen fertilization with 100% recommended doses gives effect to the growth and yield of rice.

Abstract

Composting of coffee pulp takes a long time in PT.Perusahaan Perkebunan Kalibendo. To speed up the composting time from coffee pulp, a study that was aimed to isolate cellulolytic bacteria with the ability to decompose coffee pulp pulp was conducted at Soil Bology Laboratory, Faculty of Agriculture, Brawijaya University This study consisted of two phases, i.e. isolation and selection of cellulolytic bacteria originated from compost coffee pulp, and application of the selected bacteria onto the coffee pulp. Treatments tested in the secinda phase of this study were K0 (control or without the addition of isolates), K1 (with the addition of isolate SL 1), K2 (with the addition of isolate SL 2), K3 (with the addition of isolate SL 3) and K4 (with the addition of bacterial consortium). The treatments were arranged in a completely randomized design with three replicates. Parameters observed were decomposition rate, cellulose content, pH, C organic content, total N content, and physicals condition of the produced coffe pulp compost. Results of this study indicated that isolated bacteria obtained ware able to produce cellulase enzymes that could be seen from the presence of clear zone around bacterial colonies grown on Carboxymethyl Cellulose (CMC) agar medium. Three of eight isolated cellulolytic bacteria (SL1, SL2, and SL3) were capable of forming biggest clear zone on CMC medium with an average index of cellulolitic of 1.53. Bacterial isolates originated from coffee pulp compost were capable of decomposing coffee pulp. The bacteria consortium treatment (K4) was capable of decomposing coffee pulp faster than other treatments with the decomposition rate of 2.13 g/day
