Abstract
The agricultural sector is continuously facing myriad of problems such as yield loss due to abiotic stress as well as phytopathogen infestation. There is well established evidence that the use of plant growth-promoting rhizobacteria (PGPR) would overcome those problems and in turn improve plant growth and crop yield. In this research bacteria strains were isolated from root surface and inner tissue of plants grown in highly saline soils. The characterization includes the ability to produce aminocyclopropane-1-carboxylate (ACC), siderophore, chitinase as well as their antifungal ability. Those abilities are considered the most reliable traits for promoting plant growth. A total of 32 strains were isolated and examined, with 16 surface isolates and 16 endophytes. Thirty bacteria isolates showed capability to produce ACC deaminase with a range of values around 1.8 – 29.6 µmol/mg/h. Thirty isolates were found to secrete siderophore that resulted in halo zones around 1.5 mm - 15 mm after 7 days. Moreover, the chitinase assay showed 13 isolates having the ability to degrade chitin. Interestingly, two isolates with the highest chitinase activity also showed superior ability to inhibit fungal growth. To conclude, a procedure has been demonstrated that rhizobacteria with PGPR traits can be isolated from saline soil. Furthermore, some of these PGPR candidates showed potential to not only promote plant growth but also to control fungal pathogen. This type of dual-functional stains could serve as an environmentally friendly biofertilizer and meanwhile also a biocontrol agent in sustainable agriculture.

Abstract
Water spinach (Ipomoea aquatic Forsk.) is a food for human beings and animals. It is rich in minerals, protein, dietary fibre, with high moisture content. The work was undertaken to determine contents of K, Ca, Mg, Na & P in the stems, leaves and petioles of water spinach. Atomic absorption spectrometry (AAS) and Inductive Couple Plasma (ICP) were used to determine concentration of nutrients, where one way ANOVA was applied to analyse if there is any significant differences in the macronutrient contents amongst the leaves, petioles and stems of the water spinach. If any of the results showed significant differences, Turkey post-hoc HSD test (p<0.05%) was adopted to separate the means. In addition, Pearson’s Correlation Coefficient Test was conducted between the plant macronutrients samples (leaves + stem + petioles combined) and water macronutrients data run to determine their relationships. In addition, purpose of this study is to highlight to the public which parts of the plant should be consumed and also to indicate the relationship of Water Spinach with its growing medium. The K concentration was higher than the other elements and maximum concentration was in petioles (432+27.45 mg·L-1) and stems (424.60+14.19 mgL-1). The element with the least concentration was Na (3.10+0.40 mgL-1), in the petiole. There was no difference in Mg content in leaves, petioles and stems (avg. 28.55+1.61 mgL-1). High amounts of Ca (150+0.10 mgL-1) and low amounts of P (41.11+0.01 mgL-1) were in pond water. A positive correlation of each nutrient occurred between water spinach and pond water.

Published: March 2021

AbstractWater pollution is one of the world’s main concerns today. Governments in various countries have tried to find solutions for reducing this problem. Indonesia has a great diversity of local microorganisms. Pichia kudriavzevii UMJ-L, Trichosporon asahii UMJ-A2, Burkholderia ambifaria UMJ-A1, Burkholderia stabilis UMJ-R, Gluconacetobacter saccharivorans UMJ-K, and Pseudomonas putida are local microorganisms that can be used for bioaugmentation in wastewater. The results of bioaugmentation of domestic and organic wastewater not only can be used for watering plants but also expected to have a positive value as fertilizer for the growth or production of some plants. Microorganisms in this study were the result of isolation, which is made of pellets from rice flour/bran. The pellet after mashed is used as an inoculant which acts as bioaugmentation of incubated wastewater for 4 days. The results showed that bioaugmentation fertilizer from domestic wastewater was better than other wastewater when used as fertilizer on plants. Better results, all wastewater still requires the addition of inorganic fertilizers between 25% to 50% because of the low nutrients content.

Abstract
Recently, Nanotechnology was being widely accepted in many fields due to its unique properties in enhancing the characteristics of many different kinds of materials, including asphalt binder. On the other hand, the usage of polymer nanocomposites for the production of durable asphalt mixtures has steadily replaced the use of polymer-modified binders. This study investigates the influence of nanosilica particles (NS) on rheological properties and mixture performance of asphalt modified with 2% waste polypropylene polymer (WPP). IN laboratory work, NS/WPP composite modified asphalt samples have been produced by adding three different percentages of NS particles (0.5, 1, and 2%) by weight of binder and 2 % WPP to control asphalt (60-70) penetration grade using a mechanical mixer and a homogenizer shear mixer with shear rate 27000 rpm for 10 min at mixing temperature (165 ±5) °C. The physical tests and Marshall stability were used to evaluate the NS/WPP composite modified asphalt binder properties and mixtures performance characteristics. This study found that 2 % of NS particles decrease the temperature sensitivity of WPP modified asphalt by 13% due to improving the hardness of the NS/WPP composite modified binder. The results also showed that the Marshall stability values of NS/WPP composite modified asphalt mixtures improved by 34.2% and 9.71% at 2 % NS compared with the control and WPP modified asphalt mixtures respectively. This suggests that the composite NS/WPP composite has a noticeable effect on the performance of the flexible pavement, thus increase paving’s service life.

Abstract
One of the most common natural catastrophic in the world is Landslides causing large casualties and large economic losses. In 1994, a landslide disaster struck a part of Nepal country along the llam road. This landslide caused devastation in the country at that time. In this paper, an evaluation of this landslide was conducted and deep study to mitigate the danger of these kinds of incidences. Preventing landslides is permanently significant to ensure a streamlined flow of traffic when there are roads on the area with a potential landslide incidence. The slope stability degree of the mass of landslide area is evaluated before and after preventing landslide to occur. Many slope stability methods are used such as ordinary sliced method, Bishop simplified method, Janbu simplified method, Spencer method, method of Corps of engineers and gle Morgenstern price method. The factor of safety calculated by these methods is varied by around 9 percent. The calculated factor of safety was less than one at the time of landslide incidence. In order to increase the factor of safety, various technique were suggested to mitigate Landslide such as lowering the water table, using high berm at the toe of the slope and using grouted tiebacks to support the soil mass. Lowering the water table only was not adequate to increase the factor of safety to 1.5 neither using high berm. The most active technique to increase the factor of safety was grouting tiebacks to support the soil mass at the landslide area. This technique contributed in increasing the factors of safety s more than 2 for static state and more than 1.1 for dynamic state. The software program, Rockscience slide 6.0, is used to verify the calculations and analyses from excel sheet for the ordinary and Bishop simplified method.
