Application of Biofertilizer on Rica Plants in Pangkalan Gelebak Village, Banyuasin Regency

The farmers in Pangkalan Gelebak Village have the problem of their low agricultural productivity. The high price of chemical fertilizers causes the ability of the population to purchase fertilizers to be deficient. As a result, agricultural production is still far from optimal. In addition, rice straw left alone in rice fields can become a nesting place for pests such as rats, leafhoppers, and others. Therefore, it is necessary to transfer information on appropriate science and technology, which is environmentally friendly, to overcome the problems of farmers in Pangkalan Gelebak. One way to overcome this is to provide counseling about the importance of processing rice straw into biofertilizers to increase production, train, guide, and practice techniques for making biofertilizers made from rice straw to increase agricultural production, especially rice, and practicing application techniques for biofertilizer made from rice straw. Rice straw is the raw material for rice plants for farmers in Pangkalan Gelebak Village. The method used is to make demonstration plots of rice plants organically, counseling about the importance of processing rice straw into biofertilizers to increase production, carried out from February to June 2018. The results of using 400 kg/ha + 50 % chemical fertilizers can increase rice production from 3,5 tons/ha to 5,6 tons/ha (60,00% increase) when compared to using chemical fertilizers.

Rice straw pulping trials were carried out with aqueous ammonia mixed with caustic potash to eliminate the black liquor problem in nonwood pulping. The black liquor, which contains nitrogen, potassium, and ammoniacal lignin, potentially can be used as a fertilizer for agricultural production. Excess ammonia in the black liquor was recovered by batch distillation. The black liquor was further treated for reuse by coagulation under alkaline conditions. Effects of flocculating condition, such as dosage of 10% aluminum polychloride, dosage of 0.1% polyacrylamide, and reaction temperature and pH of black liquor, were studied systematically by experiment to obtain suitable technological conditions. Infrared and other analytical techniques confirmed that major quantities of lignin, 23.73% nitrogen (dried basis), and 6.24% potassium (dried basis) existed in the flocculating residues, which has the potential to be a good solid fertilizer. The amount of delignification and the pulp screen yield for the process remained steady at 83%–85 % and 38-40 %, respectively, when reusing the supernatant four times.

An experiment was conducted at Bangladesh Institute of Nuclear Agriculture (BINA) farm, Mymensingh, Bangladesh during 2010-2011 to find out the effect of different water and organic residue levels on rice production and soil organic carbon content. Organic carbon rates from rice straw (0.5, 1.0, 1.5 and 2.0 t C ha-1 including control) were evaluated under alternate wetting and drying (AWD) and continuous flooding (CF) systems. Each treatment also received the recommended dose of chemical fertilizers excluding control. Factorial experiment was laid out in a complete randomized design with three replications. Results revealed that, maximum plant height, filled grains per tiller, 1000 grains weight, grain and straw yield were also observed in continuous flooding system in combination with 2.0 t C ha-1 in 2010 and 2011, respectively. Combined use of chemical fertilizers, 2.0 t C ha-1 fresh rice straw and continuous flooding system performed better results to reduce CO2-C gas emission, increased organic carbon and rice production with maintaining optimum soil pH level. Continuous flooding with 2.0 t C ha-1 as fresh rice straw is an effective way to reduce CO2-C emission, optimize soil pH and contribute to sustainable rice production for food security.Jahangirnagar University J.

Abstract Norfloxacin is a broad-spectrum antimicrobial agent, widely used in humans and animals for the treatment of urinary tract infections. It is a second-generation fluoroquinolone. Several analytical methods to analyze norfloxacin have been described in the literature. However, most of them are complex and require the use of large amounts of organic solvents. This paper describes the development and validation of a green analytical method for the determination of norfloxacin in raw material by FTIR spectrophotometry. This method does not require the use of organic solvents, minimizing waste generation in the process and its environmental impacts. The development of methods that promote the reduction, prevention, or elimination of waste generation has become highly attractive to the pharmaceutical industry because of the growing demand from civil society and government authorities for environmentally friendly products and services. The FTIR spectrophotometry method was validated according to International Conference on Harmonization guidelines, showing adequate linearity (r = 0.9936), precision, accuracy, and robustness. This validated method can be used as an environmentally friendly alternative for the quantification of norfloxacin in raw material in QC routine analysis.

Road Surfaces

In order to solve the problem of road dust pollution, an ecological dust suppressant for road surfaces has been developed using monomer, orthogonal, and optimization experiments and based on the dust raising mechanism. A humectant, hygroscopic agent, coagulant and surfactant and their concentration ranges have been determined through monomer experiment. The preliminary formula of the dust suppressant has been obtained through orthogonal experiment, with the water loss rate, moisture content rate, viscosity value, and surface tension value serving as experimental indexes. The optimal formula for the dust suppressor has been calculated through an optimization experiment, with the toxicity, moisture absorption and retention performance of plants, and the relative damage rate of plant seeds serving as experimental indexes. Based on the performance characterization of ecological road dust suppressant, the ecologically and environmentally friendly dust suppressant demonstrates fine moisture absorption and retention performance, good wind and rain erosion resistance, and no toxicity. The ecological road dust suppressant developed herein covers extensive raw material sources. It is ecologically and environmentally friendly, fit for most urban roads, and has a fine dust suppression effect. Meanwhile, it also can bring in good economic and social benefits, demonstrating its broad application prospects.

In this paper, using rice straw as a raw material and urea as a nitrogen precursor, a composite catalyst (a nitrogen-doped rice straw biochar at the pyrolysis temperature of 800 °C, recorded as NRSBC800) was synthesized by one-step pyrolysis. NRSBC800 was then characterized using XPS, BET, TEM and other technologies, and its catalytic performance as an activator for permonosulfate (PMS) to degrade acid orange 7 (AO7) was studied. The results show that the introduction of N-doping significantly improved the catalytic performance of NRSBC800. The NRSBC800/PMS oxidation system could fully degrade AO7 within 30 min, with the reaction rate constant (2.1 × 10 −1 min−1) being 38 times that of RSBC800 (5.5 × 10−3 min−1). Moreover, NRSBC800 not only had better catalytic performance than traditional metal oxides (Co3O4 and Fe3O4) and carbon nanomaterial (CNT) but also received less impact from environmental water factors (such as anions and humic acids) during the catalytic degradation process. In addition, a quenching test and electron paramagnetic resonance (EPR) research both indicated that AO7 degradation relied mainly on non-free radical oxidation (primarily singlet oxygen (1O2)). A recycling experiment further demonstrated NRSBC800’s high stability after recycling three times.
