Methane Bacteria

Biogas is alternative energy produced from the anaerobic activity process of methane bacteria obtained by fermentation. Anaerobic activation is a sequence of microorganism processes breaking down biodegradable materials without oxygen. Biogas is mostly produced from cow dung and tofu industry waste that has the potential to contain methane (CH4), carbon dioxide (CO2) and hydrogen sulfide (H2S). To reduce the content of (CO2) and (H2S) and to increase the element of methane gas, the purification process is needed to do. Purification can be carried out by absorption techniques using water, NaOH solution, and zeolite/silica gel. The purpose of this study is to examine the methane gas content of variations in the composition of cow dung and tofu liquid waste and the fermentation time. The method used was an experiment by varying the composition of cow dung and tofu liquid waste by 40%: 60%; 50%: 50%; and 60%: 40%, as well as variations in the fermentation time of120, 168 and 216 hours of fermentation. The results showed that the highest methane gas content in the composition of a mixture of cow dung and tofu liquid waste was 50:50 in 168 hours of fermentation which was equal to 2.806%. The content of methane gas was influenced by the fermentation time, the pH conditions in the digester, and the intensity of stirring the biogas material in the digester.

The Impact

The focus of the present study is a small biogas power plant for anaerobic fermentation of several types of animal waste raw materials used for biogas production. The impact of some of the characteristics of substances such as composition, temperature, humidity, and pH of the mixture in the bioreactor has been considered. The above is vital for optimizing the fermentation process, and also to improve the biogas production process. The plant is located in Northeastern Bulgaria and the raw liquid manure is supplied by several neighboring small farms. The annual quantities of raw waste are as follows: cow manure - 1252 t / a; chicken manure - 427 t / a and pig manure - 639 t / a. The manure is collected in a preliminary tank and then pumped to the bioreactor. The fermenter itself is a hermetically sealed and thermally insulated tank where constant temperature is maintained. It is equipped with a stirring system, which helps the mixing and homogenization of the substrate. The tests were performed during three charges of the installation. The fermentation takes approximately 23 up to 25 days. The experiments were performed during the summer and autumn seasons when the ambient air temperature varies from 28 to 45 °C. The biogas can be used as an energy carried as the obtained organic fertilizer is suitable for agriculture purposes.

Seaweed Industry

Inceptisol is one type of land order that is widely spread in Indonesia. Its distribution reaches approximately 52.0 million hectares (Kasno, 2009). Inceptisol is widely used as an intensive farm because its management is less precise, then most Inceptisol fertility rate becomes low. This is often shown by soil acidity, organic matter content, and low nitrogen, to improve such properties one of which can use the addition of organic matter. The problem that often arises is the high cost of organic fertilizer. Seaweed industry waste is a source of organic material that has not been widely utilized. Of the total raw materials processed, there is 65 to 70 percent of industrial products produced by the seaweed industry waste every day (Mandela. 2010). Usually these side products are only left to accumulate at the landfill site. Seaweed industry waste has the potential to be used as a source of soil organic matter because the organic material content of products of seaweed industry reaches 6.4% (Afif, 2011). The addition of nutrients to the application of inorganic materials is considered as an alternative step in increasing crop productivity. Based on the description above, it is necessary to conduct research to utilize the waste of seaweed industry, to get high corn production in Inceptisol. The objectives of this research are: (1) To know the effect of seaweed industrial solid waste on soil chemical properties Inceptisol and (2) growth of maize. The research was conducted in the greenhouse, while for the analysis of soil samples and the waste of seaweed industry was conducted in soil chemistry and soil physics laboratory, Department of Soil Science, Faculty of Agriculture, Brawijaya Universities. The study was conducted from May to August 2016. The soil samples used in this study were taken from Kemirisewu village, Pandaan sub-district, Pasuruan district at a depth of 0-20 cm. The waste of seaweed gel plant is obtained from PT. HAKIKI DONARTA, Pandaan Sub-district, Pasuruan Regency. The basic fertilizers used are Urea, KCl, and TSP. Maize seeds used as indicator plants are hybrid varieties of BISI-2 maize. This study used Completely Randomized Design (RAL) with 4 (four) treatments and 3 (three) replications. Addition of solid waste of seaweed with the dosage of 15 Mg/ha, increased of soil acidity and C-Organic content, besides also can increase Phosphorus and Potassium content available, Nitrogen, Phosphorus, and Potassium plant uptake, and the best growth of maize.

The addition of biochar to soils can improve soil fertility and increase agricultural productivity. We carried out a field experiment in which biochar produced from Gliricidia sepium (Jacq.) Kunth ex Walp. was added to low-fertility Brazilian planosol and tested to increase the yield of maize (Zea mays) and snap beans (Phaseolus vulgaris L.) in sequential, organic cultivation. Biochar was applied at a 15 t/ha rate, combined or not with Azospirillum Brasiliense inoculation and organic fertilizer (Bokashi). The application of biochar resulted in an increase in soil pH and of the content of macronutrients such as phosphorus and potassium. Contrary to evidence from elsewhere, biochar had a limited effect on increasing maize yield. In the case of beans, when combined with fertilizer, biochar increased the production of beans pods and biomass, but the significant increase was observed only for inoculation. Beans are the principal component of Brazilian diet and increasing productivity of beans is of upmost importance for the poorest in Brazil, and in other tropical countries.

Abstract Bokashi is an organic fertilizer made from organic materials through fermentation process. A high quality bokashi should have C/N ratio between 10-20, which normally produced from a mix raw organic material with has C/N ratio of 30. However, many studies have shown a composition of raw organic material without a calculation of C/N ratio. Therefore, the objectives of this study were to gather the initial C/N ratio of various raw material from previous published studies, calculate the C/N ratio, and examine the descriptive characteristic (colour, aroma, and texture) of bokashi made from three selected C/N ratios of raw material (30, 70, and 110) and various length of fermentation (10, 17, and 24 days). This research combined literature reviews and laboratory experimental. For laboratory experimental, Complete Randomise Design (CRD) was applied. The result showed that all bokashi produced from raw material mixture with the C/N ratio up to 110 was still acceptable to be directly applied as a fertilizer. Bokashi produced with longer fermentation time had better texture but lower aroma and colour quality.

The paper presents results coming from experiments on pilot scale plants about the possibility to integrate the organic waste and wastewater treatment cycles, using the light organic fraction produced via anaerobic fermentation of OFMSW as RBCOD source for BNR processes. The effluent from the anaerobic fermentation process, with an average content of 20 g/l of VFA+ lactic acid was added to wastewater to be treated in order to increase RBCOD content of about 60-70 mg/l. The results obtained in the BNR process through the addition of the effluent from the fermentation unit are presented. Significant increase of denitrification rate was obtained: 0.06 KgN-NO3/KgVSS d were denitrified in the best operative conditions studied. -Vmax shows values close to those typical of the pure methanol addition (about 0.3 KgN-NO3/KgVSS d). A considerable P release (35%) was observed in the anaerobic step of the BNR process, even if not yet a completely developed P removal process.

The oat β-glucan (OG) was added into set-type yogurt as a functional ingredient, in order to evaluate effects on the rheological characteristics and microstructure of set-type yogurt. When the OG concentration increased from 0 to 0.3%, the WHC gradually increased. At 0.3% OG, the set-type yogurt had the highest WHC of 94.67%. Additionally, the WHC continuously decreased, reaching the lowest WHC (about 80%) at 0.5% OG. When 0.3% OG was added, the highest score of sensory evaluation was about 85. The rheological result showed that the fermentation process went through the changes as follows: solid → liquid → solid → liquid. The addition of 0.3% OG decreased the fermentation time of set-type yogurt by about 16 min, making yogurt more inclined to be liquid. The acidity of set-type yogurt with OG was slightly higher. The result of microstructure showed that the addition of OG destroyed the three-dimensional network structure of yogurt, and some spherical aggregate particles could be clearly observed at 0.3% OG. Overall, this study provided a theoretical basis for the application of OG in set-type yogurt.
