Abstract

The volcanic ash soil in Kawi Mountain is composed by the amorphous materials consist of allophane, imogolite and ferrihydrite. Results of previous study showed that the phosphate retention in all soil profiles of northern slope toposequence of Kawimountain was less than 85%, yet the phosphate retention of volcanic ash soils is usually > 85 %. This raised a question that there is a different characteristics of soil in the northern slope tosequence of the Kawi Mountain compared to the other places. This research was conducted to study soil characteristics, mineral contents, and genesis processessoccuring in soil on the northern slope toposequence of Kawi Mountain. 5 pedons between high elevation and low elevation (P1, P2, P3, P4 and P5) to identified the soil characteristics. The Al, Fe, and Si extracted by acid oxalate, natrium pyrophosphate, and dithionite citrate to calculate the amorphous mineral content. The results show that. The results showed that there is a different in terms of the thickness of the A horizon, the C organic content and the soil acidity level that mainly found in P3 and P4 profiles. The most important soil genesis processess in the formation of the volcanic ash soils were likely clay illuviation (P5), melanization and braunification (P3), littering (P1) and the reduction of andic soil properties from the upper slope (P1 profile) up to the lower slope (P5 profile).

Abstract

The study utilized Landsat-7 ETM+ 2001and Landsat TM5 2009 based on Normalized Differences Vegetation Index (NDVI) and 457 colour composite at the study area located in Leihitu Peninsula, Ambon City District, Ambon Island, Moluccas Province. The classified satellite data under NDVI and 457 colour composite of 2001 and 2009 of 2001 and 2009 were used to determine land cover change that have occurred in the study areas. This study attempts to use a comparative change detection analysis in land cover that has occurred in the study area with NDVI and 457 colour composite over 9 year period (2001 to 2009). The results of the present study disclose that total area increased their land cover were bare land and impermeable surface, herbaceous and shrubs, low density vegetation, and medium density vegetation, while high density vegetation is decreasing in both NDVI and 457 colour composite analysis. Overall accuracy was estimated to be around 94.3 % for NDVI and for 457 Colour composites was 84.7%. The study area has experienced a change in its land cover between 2001 and 2009 in both NDVI and 457 false colour composite analyses. The whole land cover types have experienced increased in both methods, except high density vegetation. The transformations of spectral vegetation (NDVI) product more closely with actual land cover compared with 457 colour composite product.

Abstract

Marine mud and manure are potential for improving ultisol conditions, especially soil acidity, CEC, base saturation, organic acid, soil structure, soil nutrient retention, aeration, soil humidity, water holding capacity, infiltration, and supply of phosphorus for plant growth and development. Two treatments, namely planting media with 200 t marine mud /ha + 30 t manure / ha, and 400 t marine mud /ha + 30 t manure / ha were able to increase pH from 4.6 to 5.6. A significant decrease of exchangeable Alsolubility of about 0.03 meq/100 g was found in M1O3; M2O1; M2O3 and M3O1 treatments. An increase of available phosphorus about 5.02 mg/kg was found at 200 t marine mud/ha + 30 t manure/ha treatment. There was a significant increase in plant height of about 62.42 cm in the media without marine mud and 30 t manure/ha. Application of 30 t manure/ hayielded plant with leaf size of about 9552 cm2 /plantand fresh fruit of about 9.81 t/ha.

Abstract

Production of sweet potato in the dry land areas of East Java is low because of low levels of soil fertility in the region. One of alternatives to improve crop production in the area is the use of local sources of organic matters. The purpose of this study was to investigate the effects of combined biochar and residues of Mucuna pruriens L., Psophocarpus tetragonolobus L., Phaseolus lunatus L. and Dolichos lablab LB., on growth and yield of sweet potato in dry land area of East Java. A field experiment was conducted in the farmers' field at Gondanglegi village, Bandarkedungmulyo District of Jombang. The treatments tested were mixtures of each of four legume residues and biochar with the following proportion (% dry weight), 50%  legume residues + 50% biochar, 75% legume residues + 25% biochar, and 100% legume residues + 0% biochar. A control treatment with no application of legume residues and biochar was also included in the experiment. Each mixture of legume residues and biochar was applied in a 2 x 3 m field plot at a rate of 5 t/ha. Seedlings of a local variety of purple sweet potato were planted in each plot with a planting distance of 80 cm between rows and 30 cm in row. Thirteen treatments were arranged in a randomized block design with three replications. The results showed that after 4 months, application of combined biochar and residues of M. pruriens, P.tetragonolubus, P. lunatus, D. lablab affected soil fertility and growth of sweet potato on dry land areas. The combination of 2.5 t D. lablab residues/ha and 2.5 t biochar/ha produced the highest yield of sweet potato by 16.53 t/ ha, an increase of 347.9% when compared to the control treatment with no addition of legume residues and biochar.

Abstract

Lead (Pb) and cadmium (Cd) are sources of serious problems in the environment due to their reactivity and toxicity. Lumbricus rubellus is an earthworm reared by people is expected to reduce Pb and Cd concentrations in the environments. The aim of this study was to explore the ability of Lumbricus rubellus in reducing excess of Pb and Cd in organic media generated from urban waste. Sixteen treatments (four levels of Pb concentration and four levels of Cd concentration) were arranged in a completely randomized design with three replications. Each treatment was placed in a wooden pot of 20 cm x 20 cm x 25 cm, and supplied with 40 Lumbricus rubellus for 30 days. Results of this study showed that 20 and 40% of the earthworm could survive until day 30 in organic media contaminated with Pb and Cd, respectively. Pb accumulated in the earthworm bodies ranged from 0.03 to 211.42 mg/kg, while the Cd accumulated in the earthworm body ranged from 0.57 to 22.11 mg/kg. The bioaccumulation factor for Pb was 46.98%, while that of Cd was 53.83%t. The content of Pb in vermicompost ranged from 0.04 to 19.41 mg/kg, while that of Cd ranged from 0.01 to 1.58 mg/kg.

Abstract

Volcanic ash from the eruption of Mount Kelud in 2014 damaged some agricultural areas grown with maize in Malang of East Java. The purpose of this study was to elucidate the effect of organic fertilizers and biological fertilizers on growth and yield of maize on soils damaged by volcanic ash from the eruption of Mount Kelud. A pot experiment was conducted in the glasshouse of Balitkabi, Kendalpayak, Malang from July 2014 to February 2015. The treatments tested in this study were combinations of three mixtures of soil and volcanic ash (90%:10%, 80%:20%, and 70%:30%), and two doses of biofertilizer (25 and 35 kg / ha). Each treatment was added with 5 t organic matter/ha. A total of 10 kg of each mixture of soil and volcanic ash was placed in a 15 kg plastic pot. Each treatment received 100 kg inorganic fertilizer / kg containing 15% N, 15% P, and 15% K. Three seeds of maize (NK33 variety) were planted in each pot and thin to one plant after one week. The experiment was conducted for 14 weeks. The results showed that application of organic matter and biofertilizer did not significantly improve fertility of soil mixed with volcanic ash from the eruption of Mount Kelud. Yield of maize was not significantly improved by the application of organic matter and biofertilizer on soil mixed with volcanic ash. The contents of carbohydrates and proteins in maize seeds were also not affected by application of organic matter and biofertilizer.

Abstract

The purpose of this study was to explore the effect of volcanic ash from the eruption of Mount Kelud and compost on the soil properties and production of sweet potato on a sandy soil. The treatments of this study were (a) a combination of and volcanic ash with the proportion of 100: 0, 90:10, 80:20, and 70:30 (% weight), (b) the addition of compost (2.5 and 5 t / ha), and (c) two varieties of sweet potato (Manohara and Ayamurazaki). The soil used in this study is the topsoil (0-30 cm) Psament or sandy Entisol obtained from sweet potato cultivation location in Sumber Pasir Village of Pakis District, South Malang. Ten kilograms of planting medium (soil + volcanic ash) for each treatment was placed in a 15 kg plastic pot. Sixteen treatments arranged in a factorial completely randomized design with three replications.  The results showed that application of Mount Kelud volcanic ash and compost was able to improve soil permeability, soil pH, organic C, and K-total, but did not significantly affect total N content, available P and K total land. The highest fresh tuber weights of 373.51 g / plant or 19.92 t / ha and 393.09 g / plant or 20.96 t / ha for Manohara and Ayumurazaki varieties, respectively, were observed in the treatment of 10% volcanic ash + 5 t compost / ha. The carbohydrate content of Manohara variety was higher than that of Ayamurazaki variety at each treatment. The highest carbohydrate content of the Manohara variety  (23.52%)  was obtained through application of  20% volcanic ash + 2.5 t compost/ha, while that of the Ayamurazaki variety (22.42%) was obtained through application of 30% volcanic ash + 2.5 t/ha.
