Abstract

Solid State Fermentation (SSF) atau fermentasi padat dianggap sebagai metode fermentasi yang paling menguntungkan dari pada Submerged Fermentation (SmF) atau fermentasi terendam. Hal ini dikarenakan bahwa metode fermentasi padat (SS) lebih ramah lingkungan, produktivitas fermentasi yang lebih tinggi, konsentrasi produk dan stabilitas yang lebih tinggi, penekanan katabolik yang lebih rendah, penanaman mikroorganisme khusus untuk substrat yang tidak larut dan juga aktifitas  sterilitas yang lebih rendah karena aktivitas air yang digunakan sangat rendah. Bacillus sp dapat digunakan untuk produksi enzim. Makalah ini mengulas aplikasi fermentasi padat (SSF) untuk produksi enzim yaitu amilase, esterase, xilanase, pektinase dan  likenase oleh Bacillus sp. Dalam produksi enzim yang menggunakan Bacillus sp adalah Bacillus cereus yang menghasilkan enzim amilase, Bacillus sp. JB-99 yang menghasilkan enzim xilanase, Bacillus licheniformis yang menghasilkan enzim likenase, Bacillus altitudinis AP-MSU  yang menghasilkan enzim esterase, Bacillus sp. DT7 menghasilkan enzim pektinase, dan banyak Bacillus sp dengan proses fermentasi padat yang menghasilkan enzim.

Abstract

Bioethanol is one of the most promising and eco-friendly alternatives to fossil fuels, which is produced from renewable sources. Bioethanol can be produced from different kinds of raw materials. Conventional crops such as corn and sugarcane are unable to meet the global demand of bioethanol production due to their primary value of food and feed. Agricultural wastes are cost effective, renewable and abundant. To do this, very high gravity (VHG) fermentation which involves use of medium containing high sugar concentration(>250g/L) must be implemented to achieve high ethanol concentration. However, VHG fermentation leads to significant stress for Saccharomyces cerevisiae due to osmotic pressure at the beginning of the fermentation and high ethanol content at the end. At this review, rice straw is the most abundant waste compared to the other major wastes and potentially produce 205 billion liters bioethanol per year, which is the highest among these four mentioned agricultural wastes.

Abstract

discoloration is the result of the action of endogenous polyphenol oxidase (enzymatic browning) followed by spontaneous polymerization of quinonoid compounds with other food components. Currently, the use of sulfite agents is the most widely used chemical approach to control browning of foods. However, consumer awareness of the risks associated with sulfites and growing regulations make sulfites an alternative. Efforts should be made to reduce the degree of browning of porang tuber chips caused by enzymatic non-enzymatic browning. The purpose of this study was to study the alternative use of sulfite as an anti-browning agent against the whiteness value of porang tuber chips. The alternative type of sulfite used is ascorbic acid. Ascorbic acid concentration (2, 5 and 7.5%) and immersion time (30, 60, 90, 120, 150 and 180 minutes) were selected as independent variables. The best condition for preventing browning of porang tuber chips was obtained by using 5% ascorbic acid at a time of soaking for 180 minutes and obtained the highest whiteness value (79.41). Keywords: anti-browning agents, lightness, chips porang

Abstract

In the last 10 years, Covid19 has emerged as an important recent shock that has had an effect on the globaleconomy. Regional resilience may have an effect on how different regions are affected. This study intends tolook at how regional resilience is affected by structural change both before and after Covid19. We identify twodifferent situations (prior to and during the Covid19 shock) that affect whether structural reform increasesregional resilience. The findings show that Covid19 has a number of negative effects on regional resilience.Additionally, raising a sector's productivity has a significant positive effect on resilience under typical conditions(prior to Covid19). A sector's increased productivity and contemporaneous workforce transfer to other sectorswith higher productivity during the COVID19 shock, however, have a significant beneficial effect on regionalresilience. Therefore, when the circumstance is stable, productivity becomes more crucial. However, amid ashock, the industry and its employees' flexibility and agility are more crucial.
