Amount of straw wastes in Ciparay, Bandung, West Java Indonesia reaches 10-12 tons.ha -1 but its has not been well managed, after harvested, the remaining unused straw is abandoned on the ground and is eventually burned. In the long run, this straw burning will be very disadvantageous to farmers, especially in terms of the environmental impacts on rice paddy including decreasing soil fertility, killing soil biota, damaging soil physical properties and wasting energy. One of alternatives to utilize rice straw able to provide added value is utilizing its waste as a material to make compost on the condition that the straw is already chopped into a size of 5-10 cm according to SNI standards. Therefore, a study on rice straw chopping technology based on the composting requirements is required. The aim of this study is to design a prototype of rice straw chopper with capacity 100 kg.hr -1 . The method used in this research is engineering design with observation of the reasearch, design criteria, functional and structural design, figure design, technical analysis, prototyping of rice straw chopper, machine functional and performance test. The measurement results of rice straw characteristics show that the average length, diameter, bulk density and moisture content of rice straw are 708 mm, 4 mm, 160.6 kg.m -3 and 34.6% wet basis. This straw chopper design were produces a prototype with a dimension of 1040 mm (length) x 1000 mm (height) x 465 mm (width) with a power source generator using 5.5 HP gasoline motor. The result of functional test of the straw chopper shows that the actual capacity of this straw chopper is 100.32 kg.hr -1 .

“…The control measures adopted worldwide have exhibited varying extent of success, but complete eradication has not yet achieved (Ray et al 2009;Patel 2012;Stubbs and Kennedy 2012). However, studies have reported that water hyacinth can be a good source of energy owing to the profuse growth and abundance (Mathur and Singh 2004;Gunnarsson and Petersen 2007;Mishima et al 2008;Chuang et al 2011;Das et al 2016). The dry plant biomass mainly comprises of cellulose (18-31%), hemicellulose (18-43%) and lignin (7-26%) Bergier et al 2012;Barua and Kalamdhad 2016).…”

Hydrogen (H 2 ) produced from biological methods is a potential option to meet the growing clean energy needs. The present study aimed to produce biohydrogen by dark fermentation from nuisance aquatic weed, Eichhornia crassipes, using facultative anaerobic bacteria. A total of 12 bacterial strains were isolated from different wastewater sources and were screened for the potential of H 2 production using glucose as carbon source. Ten strains showed the H 2 -producing potential and were identified up to the generic level by biochemical tests. Two strains with higher H 2 production were sequenced using PCR technique and identified as Proteus mirabilis and Pseudomonas aeruginosa and selected for the studies with E. crassipes as the substrate. It was found that P. aeruginosa could produce 19.54 ± 0.03% of H 2 from 2% acid (H 2 SO 4 ) treated substrate which was comparatively higher than that of 4 and 8% treatments. P. mirabilis also yielded better results of 5.42 ± 0.02% H 2 f or 2% acid (H 2 SO 4 ) treated substrate than 4 and 8% treatments. In total, 33.52 ± 0.04% of H 2 was produced by P. aeruginosa for the substrate treated with 2% alkali (NaOH). It was noted that with respect to P. mirabilis 4% alkali treated substrate yielded a higher percentage of H 2 (20.23 ± 0.03%) compared to the other two concentrations. The results indicate that alkali treated substrate produced comparatively higher amount of H 2 than that of acid treated substrates. Regarding efficiency, P. aeruginosa was found to be more competent than P. mirabilis.
