Journal of Degraded and Mining Lands Management Vol 2, No 4 (2015)
Publisher : Brawijaya University

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.

Publisher : Brawijaya University

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.

Publisher : Brawijaya University

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.

The effect of motor vehicle emission towards lead (Pb) content of rice field soil with different clay content C C Wati; S Prijono; Z Kusuma
Journal of Degraded and Mining Lands Management Vol 3, No 1 (2015)
Publisher : Brawijaya University

Motor vehicle gas emission contains lead (Pb) which is a hazardous and toxic substance. Agricultural land, especially rice field, which is located nearby roads passed by many motor vehicle, are susceptible to the accumulation of Pb. If Pb is permeated by plants cultivated in the rice field, it will be very hazardous for humans as they are the final consumers. Hence, it is essential to identify Pb content of rice-field soil initiated by motor vehicle gas emission. This study was aimed to identify the effects of motor vehicle density, the distance between rice-field and road, and the clay content of soil towards Pb content of soils in Blitar and Ngawi Regencies of East Java. The method used for the study was survey method managed by using three-factor nested design with three replicates. The results of this study showed that motor vehicle density and the distance of rice field to road provide significant affected the total of Pb content of soil. However, the dissemination pattern of Pb in the soil was irregular due to the factors of climate and environment. Before Pb reached soil surface, Pb was spread out in the air due to the effect of temperature, wind velocity, vehicle velocity, size of vehicle, and road density. Consequently, the location with low motor vehicle density and positioned faraway to the road had higher total rate of Pb than the location with high motor vehicle density and positioned nearby the road. Clay content affected the total rate of Pb content as much as 37%, every 1% increase of clay content increased the total rate of Pb as much as 0.08 mg/kg.

Publisher : Brawijaya University

Technology of Geographic Information Systems (GIS) and Remote Sensing (RS) are increasingly used for planning and natural resources management. GIS and RS is based on pixels is used as a tool of spatial modeling for predicting the erosion. One of the methods developed for predicting the erosion is a Revised Universal Soil Loss Equation (RUSLE). RUSLE is the method used for predicting the erosion associated with runoff gained from five parameters, namely: rain erosivity (R), soil erodibility (K), length of slopes (L), slope (S), and land management (CP). The main constraint encountered in the process of operating the GIS is the calculation of the slope length factor (L).This study was designed to create a plan of sustainable land use and low erosion through the RULSE erosion modeling by utilizing the remote sensing data. With this approach, this study was divided into three activities, namely (1) the preparation and analysis of spatial data for the determination of the parameters and estimating the erosion by using RUSLE models, (2) the validation and calibration of the model of RUSLE by measuring soil erosion at the scale of plots on the field, and (3) Creating a plan of sustainable land use and low erosion with RUSLE. The validation erosion shows the value of R2 = 0.56 and r = 0.74. Results of this study showed that the RUSLE model could be used in the Kalikonto watershed. The erosions at the value of the actual estimation, spatial Plan (RTRW) and land capability class in the Kalikonto watershed were 72t / ha / year, 62 t / ha / year and 58 t / ha / year, respectively

Publisher : Brawijaya University

Intensive waste management is a solution to maintain an area of ecological harmony but still can produce economic benefits that are beneficial to social welfare. So in this research, waste of shrimp farms which was just processed by using zeolite, was treated again with a few treatments, i.e. simple filters, constructed wetlands, shell, fish and composting. Simple filters were composed of stone, gravel, coral, charcoal, sand and coconut fibers. Constructed wetland system used was hybrid type which combines type of horizontal flow and type of vertical flow. The shell used was Polymesoda erosa. The fish used was Tilapia. In the composting sediment activator, biang kompos was used with the composting time of one month. The results indicated that the system ofsimple filters, constructed wetlands, shells and fish proved to be quite effective to reduce levels of pollutants in wastewater and will be more effective if treatment was accompanied with a proper aeration. While, the sediment composted into fertilizer needed to be composted with a longer time than normal composting time. This was because the composted materials were derived from wastehaving a very low nutrient, so it took longer to restore nutrients. The results also indicated the potential of shrimp farm waste of PT. IBD to be processed into clean water and fertilizer. With the appropriate policies and strategies, this can lead to the development of an integrated farming system to support sustainable coastal ecologically, economically and socially.

The rate of respiration increases with increasing temperature. It causes a problem to occur with photosynthesis result (photosynthate) generated during photosynthesis as a source of energy for metabolism of plants. The objective of this study was to evaluate of growth and the production result by affected an increasing night temperature on paddy. The simulation was performed in growth chamber with increased night temperature by 20 C (T1) and 40 C (T2) higher than normal night temperature (T0). Growth phase of rice plant treated an increase in night temperature among others on the vegetative phases continues on the generative phase (VG), was treated only on the vegetative phase (V) and treated only on the generative phase (G). The number of tillers, leaf area, number of leaf, the total dry weight of rice plant on the T2 had values that were lower than at T0 and T1. The decreased values in the parameter number of tillers, leaf area, number of leaf, and total dry weight at the end of the observation were observed on T2V and T2 VG. The T2 had longer panicle than T1 and T0, but the number of panicle, weight of seedper plant, harvest index (HI), the number of productive tillers, flowering time, harvesting time , nitrogen content in the leaves, the and percentage of open stomata values were lower than T1 and T0. T1G, T1VG, T2VG and T2G showed lower percentage of full grain than at T0. T1 and T2 treatments on VG and V resulted in the delay of flowering time. T1 and T2 on the VG phase resulted in the delay of harvesting time.

A field experiment was conducted lo learn about the effect of Bokashi and Sunn hemp (Crotalaria junceaL.)on maize production and inorganic fertilizer use efficiency on maize. The experiment was conducted in Jatikerto, Malang; at the altitude of 303 m above sea level, in Alfisol soil type, the average daily temperature ranges 21-33oC, from Juneto October 2013. The experiment was conducted as factorial, designed in a randomized block design (RBD). The first factor was dose ofinorganic fertilizer (100% ; 75% and50% of recommendation dose). The second factor was the organic fertilizer(Without organic fertilizer20 tBokashi/ ha, 20 t Sunn hemp/ha, 10 t Bokashi/ha + 10 t Sunn hemp/ha). The results showed that application of 20 t Bokashi/ha, 20 t Sunn hemp/ha, and combination of 10 t Bokashi/ha + 10 t Sunn hemp/ha, along with the application of inorganic fertilizer by dose of 100% increased the yields of maize for about 41.8%; 47.6% and 54.7% (10.73 t/ha; 11.17 t/ha, and 11.71 t/ha), respectively. The yield and nutrient use efficiency in the treatment dose of 100% inorganic fertilizer did not have any significant difference from the application of 20 t Bokashi /ha, 20 t Sunn hemp/ha, and 10 t Bokashi/ha + 10 t Sunn hemp/ha along with doses of inorganic fertilization 75% and 50%. Therefore, the organic fertilizer of 20 t Bokashi/ ha, 20 t Sunn hemp/ha, and combination of 10 t Bokashi/ha+ 10 t Sunn hemp/ha could reduce the need of inorganic fertilizer for about 50%.

Land degradation is indicative: proxies of forest land degradation in Ghana K Peprah
Journal of Degraded and Mining Lands Management Vol 3, No 1 (2015)
Publisher : Brawijaya University

How is land degradation measured? The aim of the paper is to address this research question. At the premise, the paper states that land degradation as one of the truth claims of environmental science, is not directly monitored and detectable. Observers rely on indicators to know land degradation. The issues are illuminated by theoretical reference based on the notion of critical political ecology which tries to combine realist biophysical predictions and socio-political constructions. A methodology which mixes literature review, group discussion and field work produces a set of indicators of land degradation. Indigenous farmers used the indicators to spot land degradation in the forest ecosystem of Ghana. The results reveal physical indicators of ironpan formation in farms, uphill and downhill respective lost and gain of soil fertility, roots and building foundations exposed by soil erosion and river channels that do not carry running water even in the raining season. There are biological indicators of invasive species and termite infestations as well as socioeconomic indicators of poverty implicitly taken as indicators of land degradation. The paper concludes that land degradation includes multifaceted set of processes measured by variable and error-filled indicators operating at various spatial, temporal, economic and cultural scales.

Publisher : Brawijaya University

Soils from a toposequence in northern slope of Mt. Kawi, Malang were sampled to study the effect of amorphous content on the irreversible drying properties of the soils. Water, clay, organic-C, and available P contents were measured at field capacity (KL), after air-drying for 2 days (K2) , air-drying for 4 days (K4), oven-drying at 40 °C for 1 day (Ko), as well as after rewetting K2 (KL2); K4 (KL4), and Ko (KLo). The results showed that water, clay, organic-C, and available P contents changed after drying and rewetting processes. Drying process decreased clay content but increased available P content. Clay and water content of the rewetted samples, especially after oven-drying (KLo) were lower than at initial field capacity (KL), as indication of irreversible properties. In contrast, available P and organic-C content were higher after drying-rewetting processes. Variation of water, clay, organic-C, and available P contents after drying-rewetting processes were significantly affected by respected properties at initial field capacity. These properties tended to change in accordance to Alo+½Feo content. The effect of Alo+½Feo content, however was statisticaly detected only on the water content at KLo (rewetted after oven-dried) and on organic C content at KL2 and KL4 (rewetted after air-dried for 2 and 4 days).
