Publisher : Brawijaya University

The main purpose of this study was to elucidate the effects of application of organic wastes and rotation of cropping system on soil fertility status and yields of dry field rice, maize, soybean, groundnut and mungbean in order to overcome soil degradation problems in dry land areas. Six cropping rotation systems (dry field rice-soybean-fallow, dry field rice-groundnut-fallow, dry field rice-mungbean-fallow, maize-soybean-fallow, maize-groundnut-fallow, and maize-mungbean-fallow), and six organic fertilizer rates (0, 5, 10, 15, 20 t/ha, and 25 t/ha) were arranged in a randomized block design with two replicates. The results showed that maize-groundnut-fallow and dry filed rice-groundnut-fallow cropping systems with application of 25 t/ha organic fertilizer were able to increase soil fertility status. At the two cropping systems, status of N-total, P-total, K-total, C-total, CEC, and soil pH were better than other treatments. Soil physical fertility status on maize-groundnut-fallow and dry filed rice-groundnut-fallow cropping systems with application of 25 t/ha organic fertilizer was better than other treatments. Implication of improvement of soil physic characteristic because of this treatment was capable of raising irrigation efficiency about 0.98. Soil biological fertility at the same treatments was also better than other treatments. The average of soil worms was 2.44 per m2 soil. The amount of bacteria was 3.284 x 106 per gram soil. The amount of colony was 545.78 and the average of colony forming holozone was 19.66. Application of 20-25 t/ha organic fertilizer yielded higher crop yields than application of 0, 5, 10, an 15 t/ha organic fertilizer. Maize-groundnut-fallow cropping system and 25 t/ha application of organic fertilizer resulted in the highest propriety index, with value BC-ratio 2.54, BEPproduction 61760, and BEPvalue 982.

Low crop production is acid dryland area of South Sulawesi is due to low availability of P in the soils. One of alternatives that can be performed to overcome the problems of acid soils having high level of exchangeable Al, is through the addition of organic material. In the upland areas in South Sulawesi, crop rice, maize and groundnut crop residues are readily available, but the crop residues are generally only used as animal feed or even burned. This study was aimed to elucidate the effects of groundnut compost on P uptake by maize in Ultisol of Moncongloe, South Sulawesi. Eight kilograms of air dried soil was mixed with compost according to the following treatments; 0, 10, 15, 20, 25, 30, 35 and 40 t compost/ha. All pots received 200 kg/ha KCl and 300 kg Urea/ha as basal fertilizers. Two maize seeds were planted in each pot and thinned to one plant per pot after one week. At harvest maize shoot dry weight and maize root dry weight, length of maize cop, cob weight, cob diameter, weight grains per cob, P uptake by maize, P content in maize grain, soil available P were measured. Results of the study showed that groundnut compost has the ability to improve the availability of P in the soil and increase P uptake by maize grown on an Ultisol of South Sulawesi. Application of 25 t groundnut compost/ha was the optimal rate that can be used to increase P availability in an Ultisol of South Sulawesi.

Most of P in agricultural soils is in unavailable forms for plant growth. Phosphate solubilizing bacteria can increase soil P availability. This study was aimed to isolate phosphate solubilizing bacteria from sugarcane waste compost and to test ability of the isolated bacterial to dissolve phosphate. The bacteria were isolated from three types of sugarcane waste, i.e. filter cake compost, bagasse compost, and a mixture of filter cake + bagasse + trash biomass compost. The potential colony was further purified by the Pikovskaya method on selective media. Eight isolates of phosphate solubilizing bacteria were obtained from all wasted studied. Amongst them, T-K5 and T-K6 isolates were superior in dissolving P from Ca3(PO4)2 in the media studied. The two isolates were able to solubilize P with solubilizing index of 1.75 and 1.67 for T-K5 and T-K6, respectively. Quantitatively, T-K6 isolate showed the highest P solubilization (0.74 mg / L), followed by T-K5 isolate (0.56 mg / L), while the lowest P solubilization (0.41 mg / L) was observed for T-K4 isolate. The increase of soluble P was not always followed by the decrease in pH.

The aims of this study were to elucidate heritability and the role of drought traits genes of black paddy rice for determination base of the selection method to obtain drought tolerant and high yield potential of black paddy rice. The study was conducted through two experiments during February-November 2013. The first experiment was the establishment of populations from crosses carried out in the hybridization room. The second trial was evaluation of the genetic diversity of drought properties held in the greenhouse of the Faculty of Agriculture, University of Mataram. Planting was carried out in pots without experiment design. Population of P1 (parental-Situ Patenggang), P2 (parental-Baas Selem) were 50 plants of each; population of F1, F1BC.1.2, and F1BC.1.1 were 25 plants of each, and 250 plants of F2, as well as control of drought susceptible variety (IR20) was 10 plants. To determine the heritability and the role of genes controlling drought traits were used index of bud dry and cure of IRRI standard. The results showed that crossing of black paddy rice "Baas Selem x Situ Patenggang” had relatively moderate heritability in broad sense and low heritability in narrow sense. In the crossed F1 population was found that gene action of drought trait was not perfectly dominant

The availability of nutrients, especially N, P, K in the degraded peat are very low. The high organic acids can decrease the soil pH, its causes the negatively charged nutrients such as nitrate and phosphate are also very low. Ameliorant contributes some cations both monovalent and polivalent which acts as a bridge cations, thus increasing the availability of nutrients, especially nitrogen and phosphate. The objective of research was to determine the storage efficiency of N, P, K on application of some ameliorants on degraded peat land. The experiment was conducted at the laboratory of ISARI, Banjarbaru. Peat soil collected from the degraded peat land at Kalampangan, Central Kalimantan. The treatments were 8 ameliorant formula and two control treatments (+NPK and -NPK). The treatments were arranged in CRD, with 3 replications, And using soil coloum (lysimeter). The leaching was conducted every once a week, with 1.25 liter of aquades and the volume of leachate would be recorded. N, P, K concentration in leachate were analyzed periodically at 1, 2, 4, 6, and 8 weeks after incubation. The results showed that the concentrations of N and K on each observation time were relatively same, but P increased significantly at 4 weeks after incubation. The highest concentrations of N, P, and K in leachate were ameliorant from 100% of chicken manure. The storage efficiency of N, P and K varied depending on the type of ameliorant. Ameliorant that improved storage efficiency of N and K was ameliorant which consist of 80% agricultural weed + 20% dolomite, whereas for P efficiency storage was on ameliorant which consist of 80% Chinese water chestnut (Eleocharis dulcis) + 20% dolomite.

After clearing land by burning the peat, then the weeds and undergrowth will flourish. Even sometimes, the weeds are eventually burned again. Weed is known as a destroyer plant that has to be controlled. Through proper treatment, the existing weeds in peatlands can be potentiallly exploited. The purpose of this study was to determine the calorific value of briquettes as one of peatland weeds utilization. The results showed that the calorific value ranged from 2,492 cal/g to 5,230 cal/g. The lowest calorific value was on ‘teki kecil’ grass (Scirpus grossus Lf), while the highest calorific value was observed for ‘bantalaki grass’ (Hymenachne amplexicaulis Nees). The high calorific value of the peat weeds are potential for biomass briquettes raw materials. The utilization and use of peat weed briquettes as a raw materials expected can reduce land degradation due to peat swamp burning.

The goal of this research was to explore hydrocarbon degrading bacteria on crude oil contaminated soil with potential to degrade hydrocarbon in oil pollutant. The research started by early August 2013 till January 2014. Soil sampling for this research was taken on several places with contaminated soil location such as Benakat, Rimau, and Pengabuan all of it located in South Sumatera. Conclusion from this research Isolates obtained from three (3) sites of contaminated soil and treated using SBS medium were Bacillus cereus, Pseudomonas aeruginosa, Klebsiella pnumoniae, Streptococcus beta hemolisa, Proteus mirabilis, Staphylococcus epidermis and Acinotobacter calcoaceticus. Isolates that survived on 300 ppm of hydrocarbon concentration were Bacillus cereus, Pseudomonas aeruginosa and Acinetobacter cakciaceticus Selected isolates posses the ability to degrade hydrocarbon by breaking hydrocarbon substance as the energy source to support isolates existence up to 1,67 TPH level. Based on results accomplish by this research, we urge for further research involving the capacity of isolates to degrade wide variety of hydrocarbon substance and more to develop the potential of these bacteria for bioremediation.

Publisher : Brawijaya University

Since the first gas and mud volcano spewed from well at Sidoarjo, East Java, Indonesia (called Lusi or Lapindo mud) in 2006, its keep flowing ever since. Despite the occurrence of Lusi mud volcano was debated. Either it was natural or unnatural disaster, but maintaining the impact of the mud on social and environment is important. In addition, monitoring water, land and air quality under permitable condition is urgently necessary, due to some scientist stated that the eruption of mud volcano might be impossible to stop. The Lusi’s mud was analyzed in 2009 and showed that the concentration of heavy metals were below environmental soil quality guidelines. There were no environmental effect of heavy metals (Mn, Zn, Cu, Cr, Cd, Pb, Co, Ni, Hg, and As) resulted of mud, unless when these metals are associated with other elements. In contrast, the physical and chemical of mud-water was above the environmental standard. Continues monitoring on mud and mud-water was required to protect the environment, thus human health.
