“…The yield indicates that acid extraction produces a higher yield than alkaline extraction method. According to [3], the use of NaOH will multiply hemicellulose compounds and degrade lignin in the extraction of tobacco stems. This is in line with [5], who contend that the use of NaOH will damage the components of hemicellulose and lignin which will affect the yield.…”

Tobacco stems are the agricultural waste of tobacco crops that have the potential to be utilized. Use of tobacco stems in general, only in the leave of disposal without handling. Tobacco stems have the opportunity as a source of cellulose because they have a relatively high content of cellulose. The use of proper methods also plays an important role in extracting cellulose on tobacco stems. The research aims to determine the efficiency levels of cellulose extract from tobacco stems (Nicotiana tabaccum L.) with acid extraction methods and alkaline extraction. The research used a complete randomized design with a repeated trial of 2 times. The results showed the alkaline method of producing the best results against the rendemen testing parameters, water content, hemicellulose content, cellulose content, lignin content and FTIR spectroscopy. Yield test, moisture content, hemicellulose content, cellulose content and lignin content was at the best in the alkaline extraction with a concentration of 12% the yield of 43.63%; water content of 7.54%; hemicellulose content 14.33%; cellulose content 46.17%; and 2.83% lignin content. FTIR spectroscopy test shows that all treatments have important and specific function groups on cellulose such as – OH, C-H, and-CH2, so that samples were identified of cellulose.

“…One of the largest agricultural wastes humans often ignore is tobacco stem waste. With a population range of 22,000 trees per hectare and an estimated weight of 0.5 kg of tobacco stems, Indonesia will generate more than 2 million tons of tobacco stem waste (Handayani et al, 2018). Tobacco stems contain…”

Tobacco stems contain 56.10% cellulose content, 15.11% lignin, 22.44% hemicellulose, and 44.61% total organic carbon, which can be used as a source of energy or fuel. This study aimed to utilize tobacco stems in a briquette form as alternative energy. The materials used in this study were tobacco stem waste, rice husk, wood charcoal, and coconut shell. The treatments used in this study consisted of T1 (100% of tobacco stems), T2 (80% of tobacco stem + 20% of coconut shell), T3 (80% of tobacco stem + 20% rice husk), and T4 (33.33% of tobacco stems + 33.33% of rice husk + 33.33% coconut shell). The fastest combustion rate was found at T3, 0.12 gram/sec, while T1 and T2 had the same combustion rate. T4, a mixture of various materials, had no significant difference compared to T1, T2, and T3. The highest calorific value of tobacco stem briquettes was in T4 (4127 Kcal/kg), and the lowest was in T1 (2343 Kcal/kg). The combustion rate of these tobacco stem briquettes was longer than that of charcoal briquettes, whose average burning rate is 0.234 grams/second. Overall, this study provides an overview of the best combination to create briquettes from agricultural waste.

“…Chemical treatment includes using HCl (Handayani et al, 2018), NaOH (Muryanto et al, 2016), and ionic ionic solutions (Domínguez de María et al, 2014;Sen et al, 2012). Of the various recommended strong bases, NaOH is the best base for degrading lignin.…”

Lignin is a component of lignocellulosic materials which is relatively difficult to degrade. Its presence limits the use of lignocellulosic materials when they are converted to glucose and ethanol. This objective of the studi to reduce concentration of lignin contained in rice straw, carried out enzymatic hydrolysis and fermentation Pretreatment was carried out at a temperature of 100-140ºC and a NaOH concentration of 4- 10% for 16 hours. Hydrolysis and fermentation separately with the addition of cellulase enzymes and Saccharomyces cereviceae during fermentation. The nutrients used for bacterial growth included (NH4)2HPO4 0.5 g/L, MgSO4.7H2O 0.025 g/L. The media then incubated for 15 hours in a shaker at 30°C. at 80 rpm. The results of the study achieved a decrease in lignin during 16 hours the percentage reduction in lignin concentration for variations in NaOH concentrations of 4, 6, 8 and 10% were 33.76, 44.96, 55.73 and 31.41%. The best conditions were achieved during the delignification time of 16 hours at a concentration of 8% NaOH, which was a 44.96% reduction in deligtnification. Hydrolysis and fermentation of rice straw that for 6 to 48 hours, resulted the percentage of increasing glucose and ethanol concentrations before and after pretreatment was 32.99% and 39.99%.
