Enhancement of the Quality of Onion Drying Using Tray Dryer

Previous reports showed that there has been a continuous increase in the annual production of onion in Indonesia, and it is inversely proportional to the market price. The price drop is often caused by the high water content, which makes it easy to rot. Preservation of onions through a tray dryer is a good preservation method because it is effective and does not require much energy. Therefore, this study aims to determine the effect of variations in time, material thickness, and air velocity on the drying rate of onions. The samples were sliced to a size of 2 - 5 mm, followed by drying for 60 min using a tray dryer with different air rates between 4 - 7 m/s, and the rate of the process was observed every 15 min. The results showed that the drying time reduced the humidity in the chamber. The highest rate of 0.525 g/min was obtained at the peak air rate of 7 m/s. ANOVA results revealed that variations in time, onion thickness, and flow rate have a significant effect on increasing the drying rate of onions. This indicates that the method can be an effective and efficient solution to optimize the drying of the commodity

Peningkatan nilai ekonomi kopi rempah melalui pengurusan PIRT dan manajemen kaderisasi petani perempuan Desa Tanah Wulan memberikan peluang yang menjanjikan. Selama pelaksanaan program, perempuan petani kopi menunjukkan antusiasme yang tinggi dalam membentuk kader dan melaksanakan usaha KORE yang berkelanjutan.Abstract:  Coffee is a plantation commodity in Indonesia, especially for Bondowoso Regency, East Java. One of the main coffee suppliers in Bondowoso is Tanah Wulan Village, Maesan District where the main livelihood of the residents is as a farmer. Women work as housewives so they have a lot of free time to produce raw coffee into processed coffee, so this has become an object of assistance for the team to conduct spice coffee processing (KORE) training in 2019. However, the impact of the implementation of the spice coffee processing training is still not maximum, so that since 2020 until now the Team has taken the initiative to carry out a strategy for managing home industry certification through Home Industry Products (PIRT) and assisting in the management of women's regeneration in Tanah Wulan village. The solution offered in this activity is in the form of empowering women through the management of women's regeneration in Tanah Wulan Village. The regeneration management is useful for creating people who will play an important role in production activities to market KORE products so that KORE products can run sustainably. The core activities of this program are the management of KORE product PIRT and women's assistance in Tanah Wulan village through cadre management. The economic value of spiced coffee through improving the management of PIRT and the management of the regeneration of women farmers in Tanah Wulan Village provides the promised opportunities. During program implementation, female coffee farmers showed high enthusiasm in forming cadres and implementing sustainable KORE businesses

Effect of Severity Factor on the Subcritical Water and Enzymatic Hydrolysis of Coconut Husk for Reducing Sugar Production

Preventing the further degradation of monomeric or oligomeric sugar into by-product during biomass conversion is one of the challenges for fermentable sugar production. In this study, the performance of subcritical water (SCW) and enzymatic hydrolysis of coconut husk toward reducing sugar production was investigated using a severity factor (SF) approach. Furthermore, the optimal condition of SCW was optimized using response surface methodology (RSM), where the composition changes of lignocellulose and sugar yield as responses. From the results, at low SF of SCW, sugar yield escalated as increasing SF value. In the enzymatic hydrolysis process, the effect of SCW pressure is a significant factor enhancing sugar yield. A maximum total sugar yield was attained on the mild SF condition of 2.86. From this work, it was known that the SF approach is sufficient parameter to evaluate the SCW and enzymatic hydrolysis of coconut husk. Copyright © 2021 by Authors, Published by BCREC Group.

Evaluation Of Dehydration Performance Of Belitung Taro (Xanthosoma Sagittifolium) Using Tray Dryer

Belitung Taro (Xanthosoma sagittifolium) is a plant that can be processed into various food products. The high-water content of taro and the lack of a precise drying system made this material easy to rot. This study aims to evaluate the dehydration performance of tray dryers to reduce the water content of Belitung Taro. The independent variables used were air velocity (3-6 m/s), taro thickness (1-4 mm), and drying time (30-120 min). The results showed that the optimum drying time of taro is 30 min. The dryer airflow of 5 m/s significantly reduces the water content. The thickness of the slices positively affects the drying rate. The lowest water content was obtained in drying with a thickness of 1 mm. The ANOVA results show the effect of thickness, time, and flow rate variations on the drying rate. Three types of mathematical modeling are used to estimate moisture content: Newton, Page, and Modified Page. The Modified Page equation was preferred to detect the moisture content of the taro. From this study, the optimum condition of the tray dryer can be the best solution to dehydrate Belitung Taro effectively and efficientl

Techno-Economic Analysis of Extractive Butanol Fermentation by Immobilized Cells with Large Extractant Volume

There are several challenges for ABE fermentation to be used in an industrial scale including the low of butanol yield, the high energy requirement for separation and purification, and the competeness of sugar with food demand as substrat. In this study, techno-economical aspects of ABE fermentation by using immobilized cells with large extractant volume were studied. Overall production process was designed using rice straw as raw material which is semi-hydrolyzed to produce cellobiose, glucose, xylose, and arabinose mixture. Concentrated sugar was then fed to extractive fed-batch fermentation using immobilized cells. Finally, extractant was recovered and products were purified by distillation column. By evaluating this process design for the small scale capacity of 238 kg-butanol and acetone/day, the energy requirement was 41.3 MJ/kg-butanol and acetone and the cost was 1.91 $/kg-butanol and acetone. Although the cost was higher than butanol produced by petrochemical process of 1.08$/kg-butanol, it may reduce if the scale is increased
