Mass Balance Analysis

The consumption of fuel for transportation is increasing during the last decade. Bioethanol is one of the renewable energy has a good opportunity to be applied when the lack of fossil fuel. Bioethanol is derived from the lignocellulose substance through a fermentation process. In this research, the lignocellulose came from the petai peel (Parkia speciosa). The peel was hydrolyzed using an enzyme and continuously fermented for 5 days. The aim of this research is to analyst the mass balance of the bioethanol production from petai peel (Parkia speciosa) through the enzymatic process. The enzyme used in this research are alfa amylase (10 ml) and glucoamylase (10 ml), also Saccharomyces cerevisiae used in the fermentation process. The result shows that the initial material of petai peel was 57 grams will produce bioethanol around 14 grams.

Mass Balance Analysis

Litter fall and litter decomposition were measured in old-growth coastal redwood (Sequoiasempervirens (D. Don) Endl.) forests. Hillside and bottomland areas at inland and coastal locations were selected as representative sites. Both litter-bag and insitu mass-balance analyses were used to determine decomposition rates. Average annual litter fall at the four sites ranged from 3120 to 4690 kg•ha−1•year−1. Decomposition rate constants (k) calculated from the mass-balance analysis ranged from 0.117 to 0.238 year−1. Values of k estimated from the litter-bag analysis ranged from 0.273 to 0.405 year−1. Equilibrium litter loads from mass-balance analysis ranged from 15 700 to 30 000 kg•ha−1. Equilibrium litter loads estimated from litter-bag analysis ranged from 7760 to 14 500 kg•ha−1. Litter-layer equilibrium was between 12 and 26 years using the mass-balance analysis and between 7 and 11 years with the litter-bag study. The mass-balance method for calculating decomposition constants showed that litter at coastal sites decomposed faster than at inland sites. There were no differences between upland and bottomland sites. The litter-bag method, in contrast, indicated that litter at inland sites decomposed faster than at coastal sites. Significant regressions of litter decomposition constants as functions of summer average relative humidity, temperature, vapor-pressure deficit, and litter moisture were found with the mass-balance method. There were no significant regressions of temperature and moisture variables with litter decomposition constants calculated with the litter-bag analysis.
