Abstract

Domestic sugar production is still insufficient to satisfy the national demand for sugar, and production costs are expensive. One of the ingredients that can be used to make liquid sugar is starch. This study aims to determine the response of the resulting reduced sugar by optimizing the substrate concentration, liquefaction, and saccharification time. The method used of Box Behnken Design (BBD) with combinations of 20, 30, and 40% substrate concentrations, liquefaction times of 20, 40, and 60 min, and saccharification times of 20, 40, and 60 min. The characteristics of cassava flour, such as moisture (9.208 ± 0.068%), ash (0.987 ± 0.001%), fiber (2.187 ± 0.033%), and starch (79.876 ± 0.000%), were satisfied on SNI 01-2905-1992. Liquid sugar made from cassava flour reduced the sugar content by 28.299 ± 0.101%. The optimal conditions were 40% substrate concentration, 60 min liquefaction time, and 60 min saccharification time. The characteristics of the validation liquid sugar are in accordance with the specifications for the quality requirements of SNI 01-2978-1992 in the form of moisture content, ash content, and reducing sugar of 5.194 ± 0.003%, 0.996 ± 0.000%, and 29.668 ± 0.761%, respectively. These results highlight the effectiveness of optimizing substrate concentration, liquefaction time, and saccharification time in producing high-quality liquid sugar from cassava flour. This optimization addresses the domestic demand for sugar. It provides a cost-effective solution by utilizing cassava flour, thereby supporting the local agricultural economy and potentially reducing reliance on imported sugar.

Abstract

Biogas is alternative energy produced through the process of fermenting organic materials in anaerobic conditions to produce methane gas (CH4). The quality of the biogas depends on the concentration of the CH4, the higher the content, the better the quality. One way to improve the quality of biogas so that the content of methane gases in biogases increases and can reduce gases such as CO2, H2S, and other gases is by using a scrubber that contains compound fertilizer as its purification. The objective of this research is to reuse organic waste into useful biogas as alternative energy, and to apply water as a methane gas isolator so as not to be wasted on batch and scrubber reactor processes for the purification of H2S content. The old test results of the biogas flame and the color test of the flame on the 20th and 28th days could not be done, because of the little gas formed to the pressure of the gas generated 0 atm. On the 40th day where the gas pressure generated 5 atm, but the results of the biogas fire test did not come out because the gas produced was still small so the flow of gas to the stove did not reach. Biogas production needs to be increased so that the long-standing test of flame and flame color of biogas can be done well. This research also was explored step by step to producing biogas using organic waste. In addition, consideration should be given to the use of other methods to increase gas production so that these alternative energy applications can run optimally.

Abstract

Microalgae Porphyridium cruentum has potential as a raw material for bioethanol production because it has a high carbohydrate content. These carbohydrates can be broken down into reducing sugars through the hydrolysis process. The reducing sugar obtained will be used as a substrate in the production of bioethanol. This study aimed to produce a substrate with the best-reducing sugar indicator and to determine the optimum conditions for hydrolysis of P. cruentum microalgae biomass following the Box-Behnken statistical experimental design, using Response Surface Methodology (RSM). The parameters of the optimized hydrolysis process were HCl concentration (2 - 0.2 N), temperature (60 -120 ˚C), and hydrolysis time (30-180 min). The optimum conditions that have been achieved using RSM are an HCl concentration of 1.91 N, a temperature of 60 °C, and a hydrolysis time of 180 min were predicted a maximum total reducing sugar production of 810 mg/L. The experimental result of total reducing sugar obtained at optimum conditions was 895 mg/L, which was well close to the predicted value, verifying the appropriateness of the model.Abstract is informed about the statements of the problem, methods, scientific finding results and conclusion concisely

Abstract

The province of Lampung generated 2.6 million tons of cassava and 0.28 million tons of inner cassava peel waste in 2020. This demonstrates that the value of production is closely correlated with the amount of trash generated. 44-59% starch is still present in the waste from the inside of cassava peels, and this starch can be used as an input to make liquid sugar. Using the Response Surface Methodology (RSM) tool, this study attempts to optimize the saccharification process with modifications in duration (2, 4, and 8 h) and temperature (55, 60, and 65°C). Liquification and saccharification are the enzymatic processes used to make liquid sugar from cassava peel. According to study findings, the starch yield from cassava peels was 11.54%, with corresponding levels of water, ash, starch, and crude fiber of 13.53, 0.61, and 88.32%, and 1.025%, respectively. The yield of liquid sugar obtained from saccharification of cassava peel starch is 58.36%. The water and ash contents are 58.07, 16.95, and 0.11%, respectively, with the quality of lowering sugar content. Using the RSM approach, this study was able to optimize the saccharification process of liquid sugar from cassava peel starch at a temperature of 67.07 °C and a time variation of 6.8 hours. The optimized conditions resulted in a higher yield of liquid sugar from cassava peel starch. This study highlights the potential of utilizing cassava peels as a valuable source for liquid sugar production.
