Publisher : Brawijaya University

A study that was aimed to determine the effect of organic matter from groundnut and maize biomass on the availability of N and C labile fraction was conducted in laboratory and glasshouse, Iletry, Malang. Research used randomized block design with three replications. The first factor was land use : (1). Soil from land cultivated by cassava crops for less than 10 years, and (2). Soil from land cultivated by cassava crops for more than 30 years. The second factor was type of organic matter: (1). Groundnut biomass, (2). Maize biomass, (3). Groundnut-maize biomass, with a ratio of 1:1, (4). Groundnut – maize biomass, with a ratio of 2:1, (5). Groundnut – maize biomass, with a ratio of 1:2, and (6). Without organic matter. The results showed that application of groundnut and maize biomass were affect the N and C labile fraction. Application of groundnut + maize biomass increases N and C labile fraction more 40% than without biomass as well as the landuse of planted with cassava less than 10 years was 20 % higher N and C labile fractions than the land that has been planted with cassava more than 30 years. This research showed that analysis of N or C labile fraction is more sensitif than analysis of N total or C organic. It indicates that analysis of labile fractions can be used to analyze of N and C availability in the soil, beside of N total and C organic analysis

Industry sector exerts a negative effect on the environment. Industrial waste is often disposed to the rivers. The industry contributes to the accumulation of heavy metals in the environment. In farming sector, the accumulation of heavy metals can result in water pollution and be washed into the ground. Therefore, the farming product can be contaminated with heavy metals and they can be harmful to human health. The objective of this research was to reduce the Pb heavy metal content in paddy soil. This research was taken place in the Pb contaminated paddy soil using a randomized complete block design with three factors and three replicates. This research employed combination of inorganic fertilizer, ramie and Agrobacterium sp. I3 or compost as a chelator to improve Pb uptake. The results showed that combination of the three treatments increased Pb uptake. The combination of chemical fertilizers, ramie with compost increased the Pb uptake of 11.93 μg/g or 45.9%. The combination of chemical fertilizers, ramie with Agrobacterium sp. I3 resulted in the highest Pb uptake of 12.85 μg/g or 49.8%. The combination also decreased the soil Pb level by 7.8 μg/g or 23.5% of the control.

The aims of this study were to determine seed germination rate of some local plant species in two hydroseeding mulches containing different tackifier concentration, as well as to determine the optimal hydroseeding mulch media composition for germinating seeds. This study used seeds of 13 local plant species: two species of Cyperaceae (Cyperus brevifolius, C. javanicus), five species of Leguminosae (Cajanus cajan, Crotalaria pallida, Sesbania grandiflora, S. sesban, Tephrosia purpurea), and six species of Poaceae (Eleusine indica, Paspalum conjugatum, Sorghum timorense, S. bicolor, Sporobolus indicus, Themeda arundinaceae). Two hydroseeding mulch media with different tackifier composition were mixed with seeds of each species and then sowed in pots. Each treatment was repeated three times. Moistened cotton wool was used as control and comparative media for observing seed viability. Seed germination in mulch media was observed during 13 days. The results showed that only 8 of 13 species could be germinated: S. indicus, S. timorense, T. arundinaceae, C. cajan, C. pallida, S. grandiflora, S. sesban, and T. purpurea. The highest germination rate was shown by S. sesban (67%) in M2 medium and the lowest one was shown by T. arundinaceae (2%) in both media. The fastest germination time was recorded for C. pallida and S. sesban seeds that germinated in 2 days after sowing (DAS) in both media, while S. timorense and T. arundinaceae seeds showed the lowest ones in 11 DAS. The fluid M1 medium was optimal for seeds germination of S. sesban (50%) and S. grandiflora (35%), while the thicker M2 medium was optimal for seeds germination of S. sesban (67%) and S. timorense (50%) in 13 DAS. The maximum germination rate was generally reached in 11 DAS.

Publisher : Brawijaya University

Post-mining activities in Samar left serious environmental issues. Albeit it is used to provide prosperity to its constituents, mining in the area brought with it negative impacts. Bagacay Mine, an abandoned mining area in the province was left with enourmous amount of heavy metals. This include As (6-693 ppm), Cu (9-5,279), Pb (22-354 ppm), Hg (1-5 ppm), Zn (<1-7,138 ppm) and Fe (5,900-373,500 ppm). The area was then reforested with Swietenia macrophylla, Leucaena leucocephala, Acacia mangium, Bambusa blumeana and Thysanolaena maxima but only 1 percent survived. This paper touches the nature and effects of the non-essential heavy metals and metalloids present in the area as well as the mechanism of phytoextraction. Additionally, tropical metallophytes which can be used for phytoremediation activities in the future were introduced and reviewed.

The total runoff from a catchment is dependednt on both the soil characteristics and the land use/land cover (LULC) type. This study was conducted to examine the effect of changes in land cover on the total runoff from Ofu River Catchment in Nigeria. Classified Landsat imageries of 1987, 2001 and 2016 in combination with the soil map extracted from the Digital Soil Map of the World was used to estimate the runoff curve number for 1987, 2001 and 2016. The runoff depth for 35 years daily rainfall data was estimated using Natura Resource Conservation Services Curve Number (NRCS-CN) method. The runoff depths obtained for the respective years were subjected to a one-way analysis of variance at 95% level of significance. P-value < 0.05 was taken as statistically significant. Runoff curve numbers obtained for 1987, 2001 and 2016 were 61.83, 63.26 and 62.79 respectively. The effects of the changes in LULC for 1987-2001, 2001-2016 and 1987-2016 were statistically significant (P<0.001) at 95% confident interval. The average change in runoff depths were 79.81%, -11.10% and 48.09% respectively for 1987-2001, 2001-2016 and 1987-2016. The study concluded that the changes in LULC of the catchment had significant effect on the runoff from the catchment.

Application of biochar can increase availability of plant nutrients and yield. A field experiment was conducted on anInceptisol with aim to determineresidual potassium fertilizer and biochar application on growth and yield of maize in the second season. A randomized block design was used with three replication. The treaments were residual application of potassium and biochar that consisted of biochar only (30 t/ha), and biochar plus several levels of potassium apllication (0, 50, 100, 150 and 200 kg/ha), included application of 200 kg/ha potassium without biochar. Basal fertilizersapplied in the first season were 90 kg N/ha and 100 kg P205, and in the second season was 90 kg N/ha. The results showed that residual biochar alone or combined with different levels of potassium application increased yield of maize. Residual biochar increased avalilabilty of N, P, K, Ca, and Na in the soil.

Studies on volcanic ash of Mount Merapi erupted in 2010 are limited to only characterization of mineralogical, physical, chemical, and biological properties of the volcanic ash. In order to speed up rehabilitation of soils affected by the volcanic ash, it is necessary to study the application of suitable plant species, which is called bio-mechanic conservation. The purpose of this study was to test the environmental adaptability of Canavalia virosa and Flemingia congesta in sandy soil covered by volcanic ash of Mount Merapi. This study was carried out using 2x4 Split-plot randomized block design with three replicates. The main plot of the design was plant species (Canavalia virosa and Flemingia congesta), while the sub plot was the dose of organic matter application (0, 20, 40, and 60 t / ha). Soil parameters measured were N-total, P-total, available P, available K, and organic matter contents. Plant parameters measured were plant dry weight and plant height. The results showed no significant differences in soil N, P and K contents of all treatments tested in this study after 9 weeks, except C organic content. Canavalia virosa grew well until 9 weeks, whereas Flemingia congesta started to die a 9 weeks after planting.

The growth and yield of soybeans can decrease due to competition from weeds. Various efforts have been made to control the growth of weeds such as land preparation and weeding periods. An experiment to study the effect of soil tillage systems and weeding time on the growth of weeds and soybean crop yield (Glycine max (L.) Merril) has been done in Wringinsongo Village, Tumpang Sub-District, Malang Regency from February to May 2017. The split-plot design with three replicates was used with the soil tillage system as the main plot consisting of three levels, T0: no tillage, T1: minimum tillage, and T2: conventional tillage, and weeding time as the sub plot consisting of 4 levels, P0: no weeding, P1: weeding 1 time, P2: weeding two times and P3: weeding three times. The results showed that the dominant weed species before treatment were Amaranthus spinosus (Spiny amaranth), Cynodon dactylon (Bermuda grass), Cyperus rotundus (Purple nutsedge), Ageratum conyzoides (Billygoat weed), and Portulaca oleracea (Common purslane). After treatment, the dominant weed species were Cyperus rotundus (Purple nutsedge), Amaranthus spinosus (Spiny amaranth), Ageratum conyzoides (Billygoat weed), Physalis peruviana (Cape gooseberry), and Eclipta alba (False daisy). There was no significant difference of the dry weight of weeds in conventional tillage followed by weeding 3 times at 15, 30 and 45 days after planting, and minimum tillage and no tillage. For the yield of soybeans, conventional tillage followed by weeding 3 times at 15, 30 and 45 days after planting were not significant with that of minimum tillage. The yield of soybeans was lower than that of with no tillage and no weeding.

Pepper (Piper nigrum L.) is an important spice plant of Indonesia. In Bangka Belitung Province, the main pepper producer, pepper has been the most commonly cultivated commodity. However, the production has declined from time to time. One of the causes of the decline is Pepper Fot Rot, caused by Phytophthora capsici. The rapid spread and development of the disease is mainly due to utilization of diseased plant materials for pepper cuttings and infested or diseased plantation soil. The materials used in this research included the infected soil taken from the infectedpepper plantation at Bangka Island with disease intensity of pepper foot rot 60%, inoculum of Arbuscular Mycorrhizal fungi in the zeolite medium, compost, and pepper seedling from Natar variety. This research was done by planting pepper seedling on infected soil and observing plant height, disease intensity, and infection of AM fungi on the roots. The results showed that soil from diseased pepper plants harbored high population of plant pathogens inoculum and caused the death of 9 week-old cuttings and retarded growth of the survivors. Sterilization of the infected soil with hot water vapor for 3 hours still could not control the pathogen. Good growth was observed on one node cutting planted in sterile soil amended with arbuscular mycorrhizal fungi.

Publisher : Brawijaya University

Spatial distribution of land properties and its susceptibility to degradation is essential for watershed management planning. Therefore, a study was carried out to assess spatial distribution of land susceptibity to degradation and provide some recommendations for its improvement. The location of the study was in the upper Solo sub-watershed which majority located in Central Java Province. To classify degree of land susceptibility, a watershed typhology was applied. The typhology of watershed was based on land system and land cover type. Data of land cover and slope steepness were derived from sattelite images. Land system was obtained from Regional Physical Planning Programme for Transmigration (RePPProT). The results show that 36% of the study area is covered by highly susceptible and 55% moderate susceptible to degradation. The rest are classified as very high, low, and very low suceptible to degradation. Improvement of the degraded land can be achieved by applying land use planning which is suitable with its capability, in fact agricultural areas are found at land use capability classes VI and VII which have to use for production forest and limited production forest. In addition, conservation practices need to be applied, especially for agricultural land at Vst of land capability class.
