  • Improvement of soybean productivity through the application of organic,
           inorganic, and biological fertilizers in acid soils

    • Authors: Henny Kuntyastuti, Sri Ayu Dwi Lestari, Didik Sucahyono, Sutrisno Sutrisno
      Pages: 3573 - 3583
      Abstract: Acid dry land can become a centre for soybean production through improved cultivation techniques and the use of improved varieties that are acid-tolerant. In connection with this problem, research has been carried out to evaluate the effect of the application of organic fertilizers, inorganic fertilizers, and biological fertilizers on soybean productivity in acid soils. The experiment was conducted in a screen house at Iletri, Malang, East Java, using acid dry soil from Banten, West Java. The soybean seed used in this research was Wilis variety. The evaluated treatments were a combination of types and quantities of nutrient-rich organic fertilizer with acid formula (Santap-M), NPKS Phonska inorganic fertilizer, and biological fertilizer (Iletrisoy Rhizobium and Pseudomonas sp P-solubilizing bacteria, both were Iletri collections). The results showed that the addition of organic and inorganic NPKS fertilizers on acid soils could increase soybean productivity and the population of P-solubilizing bacteria Pseudomonas sp. The recommended alternative technology component for improving soybean productivity and Banten acid soil is a combination of 1500 kg Santap-M nutrient-rich organic fertilizer + 150 kg Phonska/ha. The results of this study add to the positive list that use of organic fertilizers and inorganic fertilizers NPKS is an alternative option that needs to be considered for sustainable soybean cultivation in acid dry land.

  • Area exclosure with moisture harvesting structures relative to only
           exclosure facilitates the restoration of woody plants in a degraded area
           in Alaba Kulito, Southern Ethiopia

    • Authors: Shiferaw Alem, Adane Dinku
      Pages: 3585 - 3594
      Abstract: The study aimed to evaluate the effect of area exclosure established in a degraded area with moisture harvesting structures (EX-SWC) relative to the adjacent exclosure area without moisture harvesting structures (EX) in restoring the woody plants. Vegetation data from a total of 30 plots that has an area of 20 m x 20 m, in the EX-SWC and the adjacent EX area were collected, independently. The density of trees and seedlings, diversity, vegetation structure and Importance Value Index (IVI) were analysed. Pearson’s correlation was also used for the data analysis. The Shannon diversity index was 1.6 and 1.57 in the EX-SWC and EX area, respectively. The relative density of trees (578 stems/ha) and seedlings (1530 stems/ha) in the EX-SWC area were relatively higher than the relative density of trees (466 stems/ha) and seedlings (1202 stems/ha) in the adjacent EX area. There was no significant relationship between the number of moisture harvesting structures established in each plot and the relative density of seedlings per plot (p <0.05, R2=0.18). The relative density of seedlings at the lower height classes (1 – 60 cm) in the EX-SWC area was relatively higher than the adjacent EX area. The IVI result for most of the recorded species in the EX-SWC area was also relatively higher than in the EX area. The overall results showed that the implemented moisture harvesting structures facilitated the regeneration of woody plants in the degraded area. Therefore, we recommend implementing soil and water conservation structures in degraded area restoration projects to facilitate the regeneration of woody plants.

  • Utilizing fine coal waste as a topsoil substitute on mine reclamation

    • Authors: Wahyu Sriningsih, Iskandar Iskandar, Dyah Tjahyandari Suryaningtyas
      Pages: 3595 - 3603
      Abstract:  Topsoil in post-mined land generally has a low fertility level. Its availability is not always in sufficient quantities to meet minimal needs for mine reclamation, so substitute materials and ameliorants are needed to increase its quantity and quality. Fine coal and fly ash-bottom ash (FABA) are wastes expected to reduce the demand for topsoil and, at the same time, may improve topsoil quality. This study aimed to examine the application of fine coal as a topsoil substitution and its effect on changes in the chemical properties of topsoil and the growth of jabonv (Anthocephalus chinensis). The study was conducted in a greenhouse with a completely randomized design model with two factors. The first factor was fine coal with four levels of 0, 10, 20, and 50% from the topsoil (w/w), and the second factor was FABA with three levels of 0, 500, 1000 g/15 kg of growing media. The jabon plant was grown for 24 weeks. The results showed that up to 50% fine coal could be used as a topsoil substitution. The interaction of fine coal and FABA increase pH, organic C, total N, cation exchange capacity, available P, base saturation, exchangeable cations, and micronutrients, and reduce the amount of exchangeable Al in the soil. FABA with a dose of 1000 g/15 kg of growing media and 50% fine coal was the best treatment to increase the growth of the jabon plant.

  • Mycorrhizal status of Plantago coronopus L. in relation to edaphic
           parameters in a coastal dune of Oran

    • Authors: Souad Tabti, Fatima Zohra Bendimered-Mouri
      Pages: 3605 - 3612
      Abstract: La présente étude a été menée dans le but de contribuer à une meilleure compréhension de l'adaptation des psammo-halophytes à leurs environnements hostiles à travers la détermination de leur statut mycorhizien. Il s'agissait de l'évaluation du statut mycorhizien de Plantago coronopus L. en relation avec les paramètres édaphiques de sa rhizosphère dans une dune du littoral oranais. Des échantillons de sol rhizosphérique et de racines ont été prélevés sur trois sites situés sur les dunes de Bomo-plage, à l'ouest d'Oran. Les paramètres de colonisation mycorhizienne de la plante et les paramètres physico-chimiques du substrat ont été déterminés. Les résultats ont montré que le substrat avait une texture sablo-limoneuse, il était légèrement salin, très pauvre en eau et en nutriments, avec une forte charge de calcaire total et une faible teneur en carbone organique et en azote total. Les racines ont été colonisées par des champignons de type mycorhizes arbusculaires avec une fréquence moyenne élevée (61,34%). Les résultats de l'analyse en composantes principales ont révélé que les paramètres mycorhiziens étaient positivement corrélés avec la salinité du sol, le carbone organique et la matière organique, l'azote total et le limon. Cependant, la corrélation entre les paramètres mycorhiziens et le pH,

  • Improved the coconut shell biochar properties for bio-electricity
           generation of microbial fuel cells from synthetic wastewater

    • Authors: Junjira Thipraksa, Pimprapa Chaijak
      Pages: 3613 - 3619
      Abstract: A microbial fuel cell (MFC) is a green device that utilizes chemical energy in organic materials to generate electricity. The low-cost electrode used in this study was made from agricultural waste, coconut shells. The electrochemical properties were improved by combining oxidizing agents and microwave heating processes. The modified coconut shell electrode outperformed virgin biochar by 30.89-fold (230.13±10.11 m2/g). The maximum open-circuit voltage, current density, and power density are respectively 995.00±5.00 mV, 841.67±14.43 mA/m2, and 283.42±9.67 mW/m2. This study demonstrated that modified coconut shell biochar could be used as a low-cost alternative electrode for electricity generation.

  • Pollution and radiological risk assessments of mine wastes from selected
           legacy and active mines in the Philippines

    • Authors: Cris Reven Gibaga, Jessie Samaniego, Alexandria Tanciongco, Rico Neil Quierrez, Mariel Montano, John Henry Gervasio, Rachelle Clien Reyes, Monica Joyce Peralta
      Pages: 3621 - 3633
      Abstract: In the Philippines, legacy mines and active mine wastes pose potential threats since these may contain elevated concentrations of potentially toxic elements (PTEs) and high natural radioactivity. In this study, legacy mine wastes from the Philippine Iron Mine (PIM), Barlo Mine (BM), and Rapu-Rapu Mine (RRM) and active mine tailing from Padcal Mine (PM) were analyzed to determine the concentrations of fifteen (15) PTEs and the activity concentrations of natural radionuclides. Several quantitative risk indicators and radiological health risk parameters were utilized to determine the potential effects of these mine wastes to the natural environment and to human health. Legacy mine wastes have higher contents of PTEs and are more polluted by PTEs than PM tailing. Both enrichment factor (EF) and geoaccumulation index (Igeo) values suggest that legacy mine wastes are strongly polluted by As, Cd, Cu, and Mo. BM and RM wastes are also polluted by Pb, Sb, and Zn; PIM waste is polluted by Ni and V; and BM waste is polluted by Tl. Padcal mine tailing is only moderately polluted by Cu and Mo. The natural radionuclide activity concentrations of legacy and active mine wastes are below the global background values and the radiological hazard indices are also all lower than their permissible limits, except for 40K, 238U, and absorbed gamma dose rate in PIM due to a geogenic source. Unlike the PTEs, radioactivity in the legacy and active mine wastes are not enhanced by mining activities and is not a significant risk factor to human health.

  • Soil chemical properties in agroforestry and cassava cropping systems in
           Pati, Central Java

    • Authors: Ursulin Sacer Setyastika, Sri Rahayu Utami, Syahrul Kurniawan, Christanti Agustina
      Pages: 3635 - 3641
      Abstract: Changes in natural land use for monoculture cropping systems may affect the soil properties over a certain period of time. In an attempt to evaluate soil chemical properties in the cassava cropping system, the research was conducted in Pati Regency, Central Java. Four land use systems were compared, i.e. monoculture cassava (cultivated for 5, 10, and 15 years) and agroforestry systems in two different slopes (i.e., 8-15% and 16-40%), with four replications. Soil samples from each location were taken at a depth of 0-20 and 21-40 cm for soil chemical analysis (pH, cation exchange capacity, organic C, total N, available P, exchangeable K, Ca, and Mg). Soils in agroforestry systems had higher pH, CEC, the content of organic C, total N, exchangeable K, Ca and Mg than in cassava cropping systems, especially on the slope of 8-15%. The soil under 15 years cassava and on the slope of 16-40% had the most degraded soil chemical properties, as reflected by the lowest content of organic C, total N, exchangeable K, and slightly lower CEC and the content of exchangeable Ca and Mg. Soil chemical properties on the slopes of 8-15% were significantly better than on the slopes of 16-40%, especially in CEC and the content of organic C, total N, exchangeable K and Mg. However, there was an unclear pattern of the available P content, which was possibly due to the application of P fertilizer in cassava cropping systems.

  • Assessment of nitrate contamination and its factors in the urban area of
           Yogyakarta, Indonesia

    • Authors: Surya Damar Sasongko Putro, Wahyu Wilopo
      Pages: 3643 - 3652
      Abstract: Population growth in urban areas increases rapidly due to improving economic conditions. However, this growth is not always followed by the addition of public facilities such as clean water facilities and sewage water system networks, especially in developing countries. There are still many people who use on-site sanitation systems that will cause groundwater pollution problems. In addition, many people in urban areas still depend on groundwater for drinking water. The quality of groundwater becomes an essential factor for this purpose. One of the common groundwater problems in urban areas is nitrate concentration. Therefore, this study aimed to determine the potential groundwater contamination, the primary source of nitrate contamination in groundwater, and their influencing factor in the study area. The research method used the Cl/NO3 ratio and Cl/Br ratio to determine the source of nitrate in the study area. The groundwater contamination potential was evaluated based on depth to the groundwater table, sorption capacity above the groundwater table, permeability, groundwater table gradient, and horizontal distance from the contaminant source. In addition, the total of family members, age of the settlement, the distance of the well from the septic tank, and groundwater table depth were correlated with nitrate concentration. The results showed that nitrate levels in the research area generally exceed the maximum drinking water limit by WHO, with the maximum concentration reaching 167 mg/L. The high concentration of nitrate in the groundwater is due to contamination. According to the diagrams of nitrate versus chloride and the Cl/Br ratio analysis, the primary source of groundwater nitrate contamination is a septic tank. The higher family member and age of the settlement have a positive correlation with increasing nitrate concentration. Besides, distance from the septic tank and depth of the groundwater table is negatively correlated with nitrate concentration.

  • Land management on small islands based on settlement distribution
           patterns: studies on Sulabesi Island, Indonesia

    • Authors: Lisa Meidiyanti Lautetu, Hayati Sari Hasibuan, Rudy Parluhutan Tambunan
      Pages: 3653 - 3662
      Abstract: With limited land availability, the land use and management on the small island must be sustainable. Sulabesi Island, with an area of <2000 km2, makes it one of the small islands in North Maluku and a remote island. This condition makes Sulabesi vulnerable to land loss and faced with adverse threats both environmentally and socio-economically if the allocation of residential places does not manage appropriately. The study aimed to identify the distribution of coastal settlement land with the characteristics of the island landscape, including analyzing its suitability to coastal boundaries and recommending directions for the development of coastal settlements on Sulabesi island. The method of this study used the geographic information system (GIS) to provide a spatial picture with overlaying and buffering techniques. The data analysis used topography, slope, distribution of settlements, and coastlines with collected data sources from government agencies and remote sensing, including field observations. The analysis results showed that the settlements scattered Sulabesi island randomly and separately with linear patterns, clustering, and combinations. The distribution in the island landscape was with a dominant height at 0-200 m and a slope of 0-30% or is a flat-steep plain. Besides that also shows a mismatch of utilization between the residence and the coastal border area, so land use for future settlements can do on the more proportional ground, especially outside the coastal buffer area. The results of this study's analysis can be used for further direction in regional planning and land management on small islands.

      Abstract: Determining the oil palm dead roots contribution to total (Rt) and heterotrophic (Rh) respiration as a source of greenhouse gas/GHG emission in tropical peatland is urgently required, as well as predicting their magnitude to cope with difficulties of direct in-situ measurement. This study is designed to simulate the CO2 flux emitted from oil palm dead roots/Rdr in tropical peatland as affected by water content/WC and residence time/RT. The dead oil palm roots were cleaned, treated with control/15, 100, 150, 300, and 450%WC, and then incubated for three months. CO2 flux measurement, C, N, and CN ratio determination were conducted every month. This study demonstrated the importance Rdr among other CO2 emission sources, ranging from 0.05-2.3 Mg CO2 ha-1 year-1 with an average of 0.7 Mg CO2 ha-1 year-1. Rdr contribution for literature Rt and Rh were around 0.3 to 1.3 and 0.9 to 3.5%, respectively. As a product of microbial respiration, Rdr was affected by WC and RT, supported by analysis of variance, linear mixed effect model/REML, and multivariate analysis. 100-150%WC resulting in significant and highest Rdr, whereas the increase (300-450%WC) or decrease (15%WC) would generate lower emission. Rdr culminated in the first month after incubation; meanwhile, it declined in the following months. This study also emphasized non-linear relationships between CO2 flux and other root properties, which can be modeled conveniently using non-linear approach, particularly using polynomial and artificial intelligence-based models. The simulation presented in this study served as an initial attempt to separate Rdr from Rh, as well as to predict CO2 flux with reasonable accuracy and interpretable methods.

  • Evaluation of biochar from tea pruning residue and tea fluff compost
           utilization to alleviate soil chemical properties on an Inceptisol

    • Authors: Faris Nur Fauzi Athallah, Restu Wulansari
      Pages: 3677 - 3683
      Abstract: The inorganic fertilizer that is used excessively in tea plantations causes soil health degradation. Tea pruning residue and tea fluff are local biomass that has the potential to be used as alternatives to soil nutrient input that is not well conducted in the tea plantation. This study evaluated biochar from the residue of tea pruning and tea fluff compost as potential organic materials to improve the chemical properties of soil in tea plantations. The tea pruning residue biochar and tea fluff compost were mixed in Inceptisols in a pot experiment with treatment combinations of A = control, B = 2.5 t manure compost/ha, C= 0.25% biochar + 1 t tea fluff compost/ha, D = 0.50% biochar + 1 t tea fluff compost/ha, E= 0.75% biochar + 1 t tea fluff compost /ha, F = 0.25% biochar + 1 t tea fluff compost/ha + 2.5 t manure compost/ha, G = 0.50% biochar + 1 t tea fluff compost/ha + 2.5 t manure compost/ha, and H = 0.75% biochar + 1 t tea fluff compost/ha + 2.5 t manure compost/ha. Soil incubation was conducted for 90 days, and soil samples were analyzed for pH, organic C, available P, exchangeable Mg, and exchangeable K contents. The results showed that the mixture of 0.50% biochar + 1 t tea fluff compost /ha + 2.5 t manure compost/ha gave the most optimal improvement in soil properties. The improvement percentages of soil properties obtained were available P of 334%, Exchangeable Mg of 38%, exchangeable K of 244% and pH of 4.6.

  • Versatile synthesis of activated carbon from coconut shells: a method for
           cyanide adsorption in artisanal and small-scale gold mining wastewater

    • Authors: Achmad Gus Fahmi, Zainal Abidin, Cecep Kusmana, Erliza Noor
      Pages: 3685 - 3693
      Abstract: Over the next years, Indonesia’s traditional gold mining technique (that employs mercury amalgamation) will be gradually replaced by cyanidation as a result of a Presidential Decree that has been recently issued. The cyanide-containing waste resulting from the processing tanks of this new method will be generally sedimented and flow directly into the surrounding small rivers. This study aimed to reduce the impact of cyanide contamination on the environment by using the simple activated carbon that can be produced by artisanal small-scale gold mining (ASGM). Water samples were taken from artificial wastewater as part of three replications. The highest recorded removal of cyanide from sewage was 98.43%, with an equilibrium reached at a fixed adsorbent dosage of 0.05 g over a contact time of 24 hours. Cyanide adsorption was also found to be pH-dependent, with the highest cyanide adsorption occurring at a pH of 8. The adsorption capacity for cyanide was estimated at 12.51 mg g-1 of the adsorbent, and it was considered to function based on a Langmuir isotherm model. The findings of this study confirm that the utilized glass wool in the assessed method can increase the yield of activated carbon, thereby offering a low-cost and effective adsorbent that can be used in order to remove cyanide from ASGM wastewater.

  • Development of a land stability index for land damage assessment: the case
           of a nickel mine, North Konawe, Indonesia

    • Authors: Baba Barus, Suria Darma Tarigan, Reni Kusumo Tejo, Yuri Ardhya Stanny
      Pages: 3695 - 3702
      Abstract: Assessment of land damage has been included in several Indonesian government policies, but it tends to have zero dimensions or only one point in the year. This study tried to propose an inter-time assessment of land damage with a land stability index by including the development of knowledge and technology at nickel mining sites in the easternmost part of North Konawe Regency. Orthophoto and Digital Elevation Model (DEM) images from drones in 2020 were taken in a field survey and used as primary data. While the SPOT 5 Imagery in 2014 and National DEM were collected as secondary data. The developed method combining slope, soil, TRI (Terrain Ruggedness Index), and land cover factor has been considered moderately accurate. Applying the method between different periods has produced a temporal land stability index where a positive value means more unstable, zero means unchanged, and a negative value means more stable. The results showed that after six years, the largest area due to nickel mining in the area has not changed much or had zero value. This is because the area tends to remain a natural forest. The more stable area is located in the southern part of the study site. However, the increasingly unstable area is located in the northern part of the study site. If no reclamation action is taken, the potential for further damage will occur.

      Abstract: The vegetative coverage throughout the world is rapidly changing, which also directly affects the land degradation. Therefore, this study was intended to investigate the vegetation vulnerability analysis triggered by land use/land cover (LULC) dynamics as an indicator of land degradation conditions using Remote Sensing and GIS in Guna-tana watershed. Trend studies and cross-sectional research design was employed, which produces data from the population at a particular point in time and to examine patterns of change with a mixed research approach to examine the degree of influence to measure the sensitivity analysis. A multi-criteria decision evaluation was used to create a vegetation vulnerability map for the research area. The vulnerability model was run using four sets of parameters: closeness to the road, slope, settlement closeness, and land use planning. Landsat imageries of 1995 and 2020 was used to conduct a comparative study of land use pattern. The study area has experienced a sequence of land degradation from 1995 to 2020, according to the results of multitemporal data. Agricultural and built-up lands have increased throughout this time, while forest and shrub land has decreased. The vegetation vulnerability of the area also shows that 19.23% extreme vulnerable and 67.03% very strongly vulnerable which is more than 80% of the area is highly vulnerable to vegetation. Vegetation suitability and land management evaluation is critical for determining the risk of land deterioration, that shows the adverse effects on ecological elements due to a decrease in metabolic capacity and patch disintegration processes.

      Pages: 3715 - 3724
      Abstract: This study assessed organic matter,  N, P, and K contents in three soil types after the application of biochars and organic fertilizers for two years. The experiment was arranged in a nested design with two factors. Three types of biochar and two types of organic fertilizer were used singly or in combination on three soil types. Among the treatments, the application of tobacco processing waste biochar on Inceptisol and rice husk biochar plus manure on Entisol resulted in the highest soil organic matter and total nitrogen contents. The highest phosphorus content was observed from rice husk biochar treatment on Inceptisol and from rice husk biochar+manure treatment on Entisol and Litosol. The highest K content in Inceptisol and Litosol occurred with each biochar treated rice husk biochar+manure treatment. The highest K content in Inceptisol and Litosol was observed in each tobacco waste biochar+compost treatment and in compost treatment only, respectively.

      Abstract: Abiotic stress is a limiting factor for plant growth and development. The use of arbuscular mycorrhizal fungi can reduce the negative effects of abiotic stress. This study aimed to determine the tolerance of Nauclea orientalis inoculated with mycorrhizae to drought and waterlogging stresses. This research was carried out at the Indonesian Mycorrhizal Association’s greenhouse and Forestry laboratory University of Halu Oleo in Kendari City, Southeast Sulawesi Province, Indonesia, from March to June 2019. The study used a factorial completely randomized design consisting of two factors. The first factor was Arbuscular Mycorrhizal Fungi (AMF) inoculations (A) consisting of a control, AMF types of Acaulospora sp.-1, and Claroideoglomus etunicatum.  The secod factor was environmental stress treatments (B) consisting of a control, soil moisture 25% of field capacity, 50% of field capacity, inundated as high the polybag (9 cm high) and inundated over the polybag. The results showed that local AMF was effective in improving plant growth. Interaction between inoculation of Acaulospora sp.-1 and environmental stress significantly increased AMF colonization on the N. orientalis roots. Inoculation of C.etunicatum significantly improved the N. orientalis growth. The treatment of drought stress with a field of 50% field capacity negatively influenced plant dry weight and the relative growth of the N. orientalis.

  • Geospatial modelling of the future urban expansion map using AHP and GIS
           in Bordj Bou Arreridj, Algeria

    • Authors: Hanane Boutaghane, Khalfallah Boudjemaa, Salim Dehimi
      Pages: 3733 - 3743
      Abstract: The study aimed to determine the areas of future urban expansion in Bordj Bou Arreridj, Algeria, by using multi-criteria analysis for decision-making. First, the future population was estimated to calculate the area we would need for the horizon of 2041AD. Second, criteria that contribute to determining the best areas for future expansion were selected based on recent research literature. Six factors were adopted: (industrial areas, agricultural lands, urban areas, road network, slopes, and hydrographic network). Third, the analytic hierarchy process (AHP) was used to make a comparison of the previous standards and to extract the weights. Fourth, translating the results obtained in the (QGIS) program and extracting a digital map showing areas suitable for future urban expansion according to three classifications (high spatial suitability, acceptable, and low). The results showed that the areas with high spatial suitability it densely distributed in the northeastern and western directions with an area of 12.42 km² or 23%. It is considered an insufficient area to meet the future need of 2041 AD, which amounted to 14.20 km². Followed by areas with acceptable suitability distributed in four geographical directions, occupying an area of 15.67 km² or 35%, which is a sufficient area and can be placed as a balance to fill the deficit. While the areas with low suitability densely distributed in the east-west sides, with an area of 16.26 km² or 37%. The research proved that the integration between (AHP) and (GIS) technologies have an important role in helping decision-makers identify suitable areas for future expansion, reduce the problems of random urbanization and create a homogeneous sustainable environment. Urban development in the future.

  • The potential of intercropping of Crotalaria juncea on the reduction of Pb
           accumulation in Brassica rapa and Phaseolus vulgaris grown on
           Pb-contaminated soil

    • Authors: Yekti Sri Rahayu, Moch. Dawam Maghfoer, Tatik Wardiyati
      Pages: 3745 - 3752
      Abstract: Many factors cause increasing Pb contamination in soils, including intensive crop production, motor vehicle exhaust gas around agricultural land areas, or irrigation mixed with household. An effort is needed to minimize Pb contamination in soils. This experiment aimed to examine the potential of Crotalaria juncea L. intercropped for minimizing the accumulation of Pb in vegetable crops grown intensively using agrochemicals. The treatments tested were monoculture of Brassica rapa, monoculture of Phaseolus vulgaris, monoculture of C.juncea, intercropping C. juncea with B.rapa, and intercropping C. juncea  with P. vulgaris. Results of the study showed that planting of C. juncea reduced the total dry weight of B.rapa by 33.47% and increased the total dry weight of P. vulgaris by 17.41% compared to monoculture. Intercropping of B rapa or P. vulgaris with C. juncea reduced the total Pb concentration of B. rapa by 45.64%, and that of P. vulgaris by 16.22%. Planting of C. juncea reduced the Pb concentration in B. rapa by 21.23% (Pb 0.89 mg kg-1) and that in P. vulgaris by 76.03% (Pb 0.93 mg    kg-1). Monoculture planting of C.juncea and intercropping of C. juncea with B. rapa or P. vulgaris reduced the concentration of available Pb and total Pb in the soil to not detected value, compared to monoculture planting of B. rapa and P. vulgaris.

  • The potential of organomineral amendments in increasing the adsorption of
           lead (Pb) and cadmium (Cd) in a sandy loam soil

    • Authors: M Ghufron Chakim, Wanti Mindari, Bakti Wisnu Widjajani
      Pages: 3753 - 3762
      Abstract: Sandy loam soils contain low organic carbon and have low ion adsorption capacity. Under certain conditions, the soils contain heavy metals that are harmful to plants. Soil amendments such as biosilica and humic acid from natural sources are expected to increase the soil adsorption capacity to heavy metals. A simulation experiment consisting of two factors was conducted to explore the effectiveness of humic and biosilica, as soil amendments, in adsorbing heavy metals from soils. The first factor was biosilica dose composing 0 t ha-1 (S0), 0.5 t ha-1 (S1), 1 t ha-1 (S2), and 1.5 t ha-1 (S3). The second factor was the humic acid dose composing 0 kg ha-1 (H0), 20 kg ha-1 (H1), 40 kg ha-1 (H2), and 60 kg ha-1 (H3). The humic acid and biosilica were applied to soil contaminated with Pb and Cd. The results showed that the combination of 0.5 t biosilica ha-1 (S1) and 20 kg humic acid ha-1 (H1) significantly increased soil pH, organic C content, cation exchange capacity, and reduced the availability of Pb and Cd at 90 days after treatment. The Pb and Cd contents in plant tissue decreased from roots to grains. Humic acid treatment was more effective in absorbing Pb of 86.89-90.49% and Cd of 71.47-76.33% than other treatments.

  • Changes in peak discharge based on sago land use scenarios in the upstream
           Rongkong watershed, Indonesia

    • Authors: Yumna Yumna, Sugeng Prijono, Wahid Wahid, Srida Mitra Ayu, Witno Witno
      Pages: 3763 - 3772
      Abstract: Land use affects changes in peak discharge so that it has the potential to cause or prevent flooding. Sago has morphological characteristics that have the potential to absorb more water. This study aimed to determine the magnitude of the change in peak discharge in the upstream watershed after sago planting. Observations were made on the three growth phases of sago palms (initial, middle, and mature phases). The research stages included calculating the runoff coefficient value under sago stands at three growth phases. Peak discharge of the existing conditions (settlements, rice fields, mixed gardens, shrubs, sand dunes, forests, and water bodies) was estimated after three scenarios of sago land use. The scenarios consisted of 25% of the land area planted with sago (scenario 1), 50% for scenario 2, and 100% for scenario 3. The data were analyzed quantitatively by comparing peak discharge in the existing conditions with scenario results. The results showed that the peak discharge in the existing conditions was 52.36 m3 hour-1. Peak discharge in the initial phase of scenario 1 was 18.94 m3 hour-1, scenario 2 was 37.88 m3 hour-1, and scenario 3 was 75.77 m3 hour-1. Peak discharge in the middle phase of scenario 1 was 19.01 m3 hour-1, scenario 2 was 38.02 m3 hour-1, and scenario 3 was 76.04 m3 hour-1. Peak discharge in the mature phase of scenario 1 was 6.38 m3 hour, scenario 2 was 12.76 m3 hour-1, and scenario 3 was 26.55 m3 hour-1. The peak discharge in the upstream watershed decreased after the scenarios with the use of sago land for all growth phases, except for scenario 3 of the initial and middle phases.

  • Reclamation of a limestone quarry: effect of poultry manure and humic acid
           on the soil improvement

    • Authors: Tedi Yunanto, Suparno Suparno, Farisatul Amanah, Firdha Fajriatunnisa, Nabila Putri Wisnu
      Pages: 3773 - 3785
      Abstract: Limestone processing produces dust covering the soil around the quarry site and may affect soil fertility. Post-mining activities in a forest area are mandatory to restore biodiversity, such as tree species of non-wood products. This study aimed to determine the impact of limestone dust on soil and measure the effectiveness of soil treatment for revegetation. This study employed a randomized block design with three soil groups, i.e. uncovered with limestone dust, covered with 2.5 cm limestone dust, and covered with 5 cm limestone dust. Each group had five replications and was treated with poultry manure (0 kg m-2, 5 kg m-2, 10 kg m-2, and 15 kg m-2) and 2 L of 1% (v/v) humic acid. The amendment of manure and humic acid increased the soil organic C, total N, C/N ratio, and exchangeable K but increased the soil available P content. The soil respiration and total bacteria increased along with the thinning of the limestone dust. Overall, the treatments significantly affected pH, C/N ratio, exchangeable K, and electrical conductivity. At the same time, the group significantly affected organic C, total N, C/N ratio, exchangeable K, electrical conductivity, cation exchange capacity, bulk density, total bacteria, and clay. Based on land suitability assessment guidelines, the soil required nutrient improvement and pH reduction to grow proper non-wood products tree species.
