Journal of Degraded and Mining Lands Management Vol 1, No 4 (2014)
Publisher : Brawijaya University

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.

Publisher : Brawijaya University

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.

Characteristics of Lusi mud volcano and its impacts on the Porong River B D Krisnayanti; D S Agustawijaya
Journal of Degraded and Mining Lands Management Vol 1, No 4 (2014)
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.

Utilization of maize cob biochar and rice husk charcoal as soil amendment for improving acid soil fertility and productivity N Nurhidayati; M Mariati
Journal of Degraded and Mining Lands Management Vol 2, No 1 (2014)
Publisher : Brawijaya University

The decline in soil fertility in agricultural land is a major problem that causes a decrease in the production of food crops. One of the causes of the decline in soil fertility is declining soil pH that caused the decline in the availability of nutrients in the soil. This study aimed to assess the influence of alternative liming materials derived from maize cob biochar and rice husk charcoal compared to conventional lime to improve soil pH, soil nutrient availability and maize production. The experiment used a factorial complete randomized design which consisting of two factors. The first factor is the type of soil amendment which consists of three levels (calcite lime, rice husk charcoal and cob maize biochar). The second factor is the application rates of the soil amendment consisted of three levels (3, 6 and 9 tons ha-1) and one control treatment (without soil amendment) . The results of this study showed that the application of various soil amendment increased soil pH, which the pH increase of the lime application was relatively more stable over time compared to biochar and husk charcoal. The average of the soil pH increased for each soil amendment by 23% (lime), 20% (rice husk charcoal) and 23% (biochar) as compared with control. The increase in soil pH can increase the availability of soil N, P and K. The greatest influence of soil pH on nutrient availability was shown by the relationship between soil pH and K nutrient availability with R2 = 0.712, while for the N by R2 = 0.462 and for the P by R2 = 0.245. The relationship between the availability of N and maize yield showed a linear equation. While the relationship between the availability of P and K with the maize yield showed a quadratic equation. The highest maize yield was found in the application of biochar and rice husk charcoal with a dose of 6-9 t/ha. The results of this study suggested that biochar and husk charcoal could be used as an alternative liming material in improving acid soil fertility and productivity.

Application of drip irrigation technology for producing fruit of Salak ‘Gula Pasir” (Salacca zalacca var. Gulapasir) off season on dry land I N Rai; I W Wiraatmaja; C G A Semarajaya; N K A Astiari

Publisher : Brawijaya University

Sugar naturally bark (Salacca zalacca var. Gulapasir) flowering every three months or four times a year, but only one or two flowering seasons are the flowers can develop into fruit. The condition causes granulated sugar fruits available in the market in a short period of time (only 2-3 months) ie at the time of harvest (on-season) from December to February, while outside the harvest season (off-season) fruit supply rare or no fruit. Occurs due to the nature of seasonal fruit Salak Sugar planted on dry land, irrigation depends only on rainfall, drought occurs when water is short so that the plant's internal water content is low and it causes a high failure rate develops into the fruit (fruit-set failure). The research aims to overcome the failure of fruit-set as drip irrigation. The study of the factors with two levels of treatment (without drip irrigation / control and with drip irrigation) during the dry season in central bark Sugar production (in Sibetan village, District Bebandem, Karangasem regency, Bali) at two harvest seasons, the season Gadu (July) and Sela II (October). Each treatment was repeated 16 times. The results showed that the plant was given a drip irrigation treatments provide fruit-set percentage was significantly higher compared with plants that are not given drip irrigation, both in summer and in winter Sela Gadu II. Percentage fruit-set on the season and Sela Gadu II in a given crop drip irrigation respectively 75.30% and 93.13%, while that does not get a drip irrigation percentage of its fruit-set each only 59.94% and 61.67%. Increased fruit-set on drip irrigation treatment is associated with increased leaf chlorophyll content, relative water content (RWC) leaves, and nutrient content of N, P, and K leaf. The increase of fruit-set led to a number of fruits and fruit weight per plant on providing drip irrigation significantly higher than the control. Based on the results of this study suggested treatment of drip irrigation can be applied to produce granulated sugar fruits out of season were planted on dry land.

Food security and vulnerability modeling of East Java Province based on Geographically Weighted Ordinal Logistic Regression Semiparametric (GWOLRS) model N W Surya Wardhani; H Pramoedyo; Y N Dianati

Publisher : Brawijaya University

Modeling of food security based on the characteristics of the area will be affected by the geographical location which means that geographical location will affect the region’s potential. Therefore, we need a method of statistical modeling that takes into account the geographical location or the location factor observations. In this case, the research variables could be global means that the location affects the response variables significantly; when some of the predictor variables are global and the other variables are local, then Geographically Weighted Ordinal Logistic Regression Semiparametric (GWOLRS) could be used to analyze the data. The data used is the resilience and food insecurity data in 2011 in East Java Province. The result shows that three predictor variables that influenced by the location are the percentage of poor (%), rice production per district (tons) and life expectancy (%). Those three predictor variables are local because they have significant influence in some districts/cities but had no significant effect in other districts/cities, while other two variables that are clean water and good quality road length (km) are assumed global because it is not a significant factor for the whole districts/towns in East Java.

Wheat is not currently grown as a commercial crop in Indonesia, however since consumption of wheat is steadily increasing and alternative dry season crops are required for farming system diversification, wheat is important to be adapted. Lombok Island has an opportunity for wheat growing and wheat is an alternative crop in drylands. The aims of this experiment is to adapt and screen wheat varieties including national and introduced Australian varieties in lowland Lombok Island. In future, wheat is expected to be an alternative crop for degraded lands. The experimental method used to evaluate growth and yield of 10 wheat varieties to look at the adaptability on the lowland of 200 m asl (Pringgarata) and on higher land of 400 m asl (Aik Bukak). The results showed that at a lower altitude (Pringgarata), wheat growth is slower than in Aik Bukak, which can be caused by the temperature at 200 m asl has exceeded the tolerance limit for grain growth (supra optimal temperature). Wheat can give good yields on 400 m asl, but the yield is decreased at 200 m asl (average 1.68 t/ha vs 0.82 t/ha). This low yield is mainly due to sterility indicated by the low number of grain/spikelet (<2 grain/spikelet). There is genetic variation of wheat crop responses adapted to the lowlands. Nias, Dewata, Mace and Estoc give good yields (> 2 t/ha ), higher than other varieties.

Publisher : Brawijaya University

Land degradation became more and more widespread, especially in areas with a dense population and dependence on agriculture is high enough. Land degradation can be approximated by the susceptibility of land to erosion. This study aims to identify existing land degradation in the Juana watershed, Central Java. The method used is the analysis of the typology of the watershed. This method is based on the interaction between landforms and land cover. The results showed that the degradation of land in the watershed very heavy scattered in the upstream areas in the territory of the Kudus and Pati regency. While severe land degradation are also scattered in Kudus, Pati, and Blora regency. Almost all of these degraded areas are used for dry land farming. By knowing the rate of spread of land degradation, the authority having jurisdiction in this district offices on issues related to land degradation can plan the actions necessary to resolve or mitigate land degradation in each region so that a major disaster will not happen or the impact can be minimized.

Effects of humic acid-based cation buffer on chemical characteristics of saline soil and growth of maize W Mindari; N Aini; Z Kusuma; S Syekhfani
Journal of Degraded and Mining Lands Management Vol 2, No 1 (2014)
Publisher : Brawijaya University

Humic acid is believed to maintain the stability of the soil reaction, adsorption / fixation / cationic chelate, thereby increasing the availability of water and plant nutrients. On the other hand, the dynamics of saline soil cation is strongly influenced by the change of seasons that disrupt water and nutrient uptake of plants. This experiment was aimed to examine the characteristics of the humic acid from compost, coal, and peat and its function in the adsorption of cations (K+ and NH4+), thus increasing the availability of nutrients and growth of maize. The treatments tested were combination of three sources of humic acid (compost, peat and coal), two types of cation additives (K+ and NH4+), and three doses of humic acid-based buffer: 10, 20, and 30 g / 3kg. The treatments were evaluated against changes in pH, EC, cation exchange, chlorophyll content, plant dry weight and plant height. The experimental results showed that the addition of K+ and NH4+ affected the value of pH, CEC, K+, NH4+ and water content of the buffer. Application of humic acid-based buffer significantly affected exchangeable Na and exchangeable K. Humic pH dropped from > 7 to about 6.3, EC soil was about 0.9 mS / cm, exchangeable Ca, exchangeable Mg, exchangeable Na, and exchangeable K, respectively, were around 15.57-20:21; 1.76-6.52; 0.40-0.56 and 0.05-0.51 me / 100g soil. Plant growth (plant height, chlorophyll content, leaf area, and stem weight) at 35 days after planting increased with increasing dose of humic acid. The dose of 20g peat humic acid + NH4+ or 30g peat humic acid + K+ per 3 kg of saline soil gave the best results compared to the growth of maize from other treatments.

Application of organic matter to enhance phytoremediation of mercury contaminated soils using local plant species: a case study on small-scale gold mining locations in Banyuwangi of East Java N Muddarisna; B C Siahaan
Journal of Degraded and Mining Lands Management Vol 2, No 1 (2014)
Publisher : Brawijaya University

The discharge of small-scale gold mine tailing to agricultural lands at Pesanggaran village of Banyuwangi Regency caused soil degradation as indicated by reduced crop production. This soil degradation is mainly due to the toxicity of mercury contained in the tailing. The purpose of this study was to explore the potential of three local plant species, i.e. Lindernia crustacea, Digitaria radicosa, and Cyperus kyllingia for phytoremediation of agricultural land contaminated gold mine waste containing mercury, and its influence on the growth of maize. Six treatments (three plant species, and two levels of organic matter application) were arranged in a randomized block design with three replicates. Maize was grown on soil after phytoremediation for 8 weeks. The results showed that among the three plant species tested, Cyperus kyllingia was the potential candidate plant species for phytoremediation of soil contaminated with gold mine tailing containing mercury because of its ability to accumulate mercury from 32.06 to 73.90 mg / kg of soil in 60 days. Phytoremediation of mercury contaminated soil using Cyperus kyllingia using increased maize yield by 126% compared to that the biomass yield of maize grown on soil without phytoremediation. Induce phytoremediation needs to be carried out to accelerate the process of remediation of mercury contaminated soils.
