Abstract

Solid fermentation (SSF) has built credibility in recent years in the biotechnology industry because its application has the potential to produce biologically active secondary metabolites, in addition to animal feed, fuel, food, industrial chemicals and pharmaceutical products, it has also emerged as an alternative interesting method that replaces the submerged fermentation method(SmF). This paper reviews the meaning of SSF, the factors that influence the success of SSF, the advantages and disadvantages of SSF, the meaning of cellulase enzymes, the use of cellulase enzymes and the production of cellulase enzymes using SSF from waste. The waste consists of agricultural waste and food processing waste with various microorganisms, optimization and pretreatment. So that the various levels of enzyme activity produced depend on the type of waste.

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

Tanaman padi merupakan salah satu komoditas pangan yang harus terpenuhi kecukupannya untuk menunjang kelangsungan hidup sebagian besar penduduk Indonesia. Dalam rangka peningkatan produktivitas tanaman padi salah satu faktor penghambatnya adalah adanya organisme pengganggu tanaman yang menyerang tanaman padi adalah keong mas. Teknologi pengendalian hama keong mas yang ramah lingkungan adalah penggunaan ekstrak serai karena tanaman serai mempunyai senyawa aktif sitronela yang dapat membunuh keong mas. Tujuan dari penelitian ini untuk mengetahui pengaruh kosentrasi ekstrak serai dan lama waktu kontak terhadap mortalitas keong mas. Penelitian dilakukan melalui tiga tahap yaitu penyediaan ekstrak serai, pengumpulan keong mas dan pengujian aktivitas moluskasida menggunakan ekstrak sereh dengan konsentrasi 0%, 15%, 25% dan 50% pada populasi keong mas dan dilakukan pengamatan setiap empat jam selama 24 jam. Hasil penelitian menunjukkan bahwa ekstrak sereh dapat membunuh keong mas dan hasil terbaik adalah kosentrasi 50% dan waktu kontak 24 jam. Pada konsentrasi ini seluruh keong mas sudah mati, mengeluarkan banyak lendir, warna cangkang sudah memudar dan rapuh serta tubuh keluar dari cangkangnya.

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

Aeroponics is a method of cultivating plants without using soil. Aeroponics is generally used for cultivating vegetable types. Community service in the form of counseling on the development of AeroFarms vegetable cultivation and the manufacture of aeroponic plants in Pabuaran village, Cisauk sub-district, Tangerang district, Banten province, is motivated by the lack of use of technology as a means that can help fulfill daily needs even as employment and community economic improvement. This activity aims to provide knowledge about environmentally friendly technology that is easy for the residents, namely the development of aeroponic plant cultivation, and provide knowledge about creativity in farming to the community and utilizing natural resources around. The material contains an understanding of aeroponics, the history of aeroponics, various aeroponic methods, stages of aeroponic planting, and the advantages of using aeroponic methods. The implementation of AeroFarms-based collective vegetable cultivation development activities can create community creativity, become a solution for the conversion of agricultural land and can maintain and improve household food security.

Abstract

Community service in the form of domestic liquid waste treatment at Banksa Suci (Cisadane River Garbage Bank) Ciheuni is motivated by domestic wastewater flowing into the Cisadane river and passing through the Banksa Suci Ciheuni park which has been polluted with black waste water showing. The waste water comes from the area around the Banksa Suci Ciheuni park which consists of residential areas, offices and hospitals. Polluted wastewater that flows into the Cisadane river can contaminate the Cisadane river body and its ecosystem. This activity aims to purify the waste sample water so that it is in accordance with the quality standards. This community service is carried out by adding golden snail shell powder to wastewater, with a concentration of 0%, 10% and 20% then stirring and filtering, then analyzed in the laboratory. The results of the analysis show that the golden snail shell is able to reduce the turbidity of the holy banksa wastewater.
