Abstract

The Generated Biogas Rate (GBRT) model and the Predicted Maximum Biogas Potential and Yield (PMBPY) model were developed in this work for better understanding of the anaerobic co-digestion of vinasse waste and tofu residue at variation of total carbon/total nitrogen (C/N) ratio which was 3.71, 5.26, 7.30, 32.54, 97.34. Rate constant (k (/day)) and biogas production rate (ū (mL/day)) estimated using GBRT model was 0.071, 0.140, 0.153, 0.150, 0.125 /day and 20.206, 101.393, 111.832, 95.967, 58.616 mL/day respectively for all variables (R2 of 0.925 – 0.976). The maximum biogas potential (Pm) obtained using PMBPY model for all variables was 335.8317, 737.0868, 760.4523, 608.3871, 523.3872 mL respectively (R2 = 0.914 – 0.972). The fitting error between measured biogas and predicted biogas through the developed model was 0.20 – 7.03 %. The developed kinetic model can predict biogas potential with prediction efficiency (%) over modified Gompertz model of 91.71 – 98.57%.

Abstract

Rice straw is a rice plant whose fruit (grain) has been removed, so only the stems and leaves are left. Rice straw is the largest among rice plant waste and has not been utilized as well. Utilization of rice straw waste is not optimal because its usually used for cattle feed and as organic fertilizer. Apart from being used as cattle feed and organic fertilizer, methane gas can still be used for alternative renewable energy sources such as biogas. Rice straw has a carbon-to-nitrogen (C/N) ratio content between 50-70. However, to achieve the optimum biogas formation, the substrate requires a C/N ratio of 20-30, therefore a combination of other waste mixtures, such as cow dung or waste that has a low C/N ratio content is usually carried out.

Abstract

The purpose of this study was to investigate biogas production from bioethanol vinasse using the simple method which was triple batch digester in series mode. Three digesters (A, B, C) were used in laboratory scale and carried out in 30 days respectively. The fresh rumen was added in substrates before that were put into each digester (A, B, C). Ratio of COD/N in substrat was adjusted in variation of 1436/7, 400/7, 500/7, 600/7, 700/7. The results showed that in digester A, biogas was produced in large amount a first time of fermentation. In digester B, biogas generated was less than that in digester A. Meanwhile, in digester C, biogas was not produced again. Ratio of 500/7 and 600/7 generated the most biogas volume which was 9,322 and 9,168 mL. Keywords: Bioethanol, Biogas, Series Method, Triple Batch, Vinasse,

Abstract

Cows are ruminant livestock used as a source of food and the economy. Besides that, cows also produce waste, namely cow dung. If cow dung piles up in the open and spreads, it will carry by rainwater to lower places, which can cause soil and air pollution. To reduce cow dung waste can be used as a substrate in an anaerobic digester to produce biogas. Important factors that can affect the biogas rate include pH, temperature, Total Solid (TS) and Volatile Solid (VS) content, and the C/N ratio. The yield of biogas can be optimal with pretreatment and co-digestion. The potential for cow dung can generate electricity of 5,580 kW per day from 18 million head of cattle.

Abstract

River is one of the resources for water because it is popular for human necessary,especially used in washing, bathing and cooking activity. At this era, the pollution isdesecrated by industrial and domestic waste. Hence, the quality of water on rivers hasdecreased. Cibanten river located in Banten Province-Indonesia country is one of theriver, whose water quality is decreased by pollution. The characteristics of Cibanten riveris Total Dissolved Solid (TDS) of 416 ppm, Total Suspended Solid (TSS) of 100 - 900 ppm,pH level of 6-8. Therefore, watertreatment must be done before the water is used.Biofiltering technology with gravity system was chosen, It utilized the combination ofcoconut fibrous and zeolite active (activation without chemical). This Equipment calledGRATIS (Gravity-fed Biofiltering System). Result from this treatment, TDS decreased to249 ppm (sample 2) and 185 ppm (sample 3), pH increased to 7.23 (sample 3) and 8.5(sample 2), TSS decreased to 9-115 ppm with fed water of TSS about 1048 ppm. Turbiditypoint decreased about 99.5 % (sample 2) and 99.7% (sample 3). BOD (biological OxygenDemand) decreased about 83.9% (sample 2) and 87.1% (sample 3) and COD (ChemicalOxygen Demand) decreased about 30.8% (sample 2) and 38.5% (sample 3).
