Abstract

Breadfruit (Artocarpus communis Forst.) is one of sources for ethanol production, which has high starch content (89%). Ethanol production from breadfruit starch was conducted by Simultaneous Saccharification and Fermentation (SSF) technology using microbes consortium. The aim of the research was to examine a method to produce ethanol by SSF technology using microbes consortium at high yield and efficiency. The main research consisted of two treatments, namely normal SSF and enginereed SSF. The results showed that normal SSF using aeration and agitation during cultivation could produce ethanol at 11.15 ± 0.18 g/L, with the yield of product (Yp/s) 0.34 g ethanol/g substrate; and yield of biomass (Yx/s) 0.29 g cell/g substrate, respectively. A better result was obtained using engineered SSF in which aeration was stopped after biomass condition has reached the end of the exponential phase. The ethanol produced was 12.75 ± 0.04 g/L, with the yields of product (Yp/s) 0.41 g ethanol/g substrate, and the yield of cell (Yx/s) 0.09 g cell/g substrate.

Abstract

Quality is an absolute requirement used by product to compete in the global market. Therefore, as the competition is getting more tight , high-quality gambier products become an absolute demands that must be met. One of the steps that must be taken is continuous technological improvement. In this study, quality analysis of various raw gambier samples of Lima Puluh Kota regency and the Padang City in West Sumatera, and Musi Banyu Asin regency in South Sumatra was done. The results of dimensional measurement and weighing samples of Bootch Gambier, Lumpang Gambier, Wafer Block and Stick Gambier showed that the quality of raw gambier were very various. The variation occured because the drying process and storage of gambier were not good enough. The proximate analysis data showed, in terms of ash content, only two types of Gambier samples (Bootch CVR Gambier and Wafer Block CVR Gambier) that met quality requirements, whereas the Coin Gambier and Bootch CVA Gambier had a very high ash content (38.93 percent and 75.64 percent).

Abstract

The purpose of the research was to investigate the effects of PEG 400 addition on the characteristics of bioplastic polyhydroxyalkanoates (PHA). PHA was obtained by cultivating Ralstonia eutropha on hydrolysed sago starch substrate using fed batch method for approximately 96 hours. The biomass concentration obtained was 4 g/L with PHA yield 20-30% of dry cell weight. The bioplastic was formed with solution casting method in which chloroform was used as solvent and PEG 400 was used as plasticizer. The concentrations of PEG 400added were 10, 20, and 30% (w/w), respectively. Bioplastic properties which were tested were tensile strength, elongation to break, density, thermal properties, cristalinity, and functional group. The addition of plastisizer tend to increase tensile strength and elongation to break, but decrease density, cristalinity and melting point. Bioplastic with 30% PEG 400 addition gave the best results. Bioplastic with 30% PEG 400 gave a value of tensile strength of 0.083 MPa; elongation to break of 0.881%; density of 0.7881 g/cm3;  melting point of 158.95 ac; and cristalinity of 44.58%. With these properties, the resulted bioi plastic may be used for surgical strings. Keywords: Bioplastic, Polyhydroxyalkanoates (PHA), Ralstonia eutropha, hidrolysed sago starch, PEG 400

Abstract

The objective of this research is to study the scaling up of bionsecticide production from Bacillus thuringiensisvar. israelensisusing onggok (a cassava by-product) as a carbon source. The insecticide produced was used to eradicate Aedes aegypti larvae. The product was a crystal protein produced during bacterial sporulation. Scaling up from laboratory to pilot plant scale was done using two methods, i.e. constant agitation power per unit volume (Pg/V) and constant oxygen transfer coefficient (kLa). The results showed that yield of product per substrate (Yp/s) of Pg/V based product with the value of 3.52 ± 0.02 spora per gram substrates was higher than Yp/s of  kLa based product with the value of 2.96 spora per gram substrate.  Logarithmic value of viable spore count (log of VSC) was also higher, i.e. 7.23 ± 0.30 for Pg/V based product as compared to 7.17 ± 0.20 for kLa based product. Substrate efficiency was also higher in Pg/V based (92.47%) than kLa based (64.87%). LC50 of Pg/V based product was lower (0.49 μg/ml) meaning that it was more toxic than kLa based product (0.62 μg/ml). Amino acid content of Pg/V based product was also higher than kLa based product. Constant Pg/V method was suggested as a based on the scaling up of bioinsecticide production of B. thuringiensis israe/ensison industrial scale. Keywords: bioinsecticide, Bacillus thuringiensisvar. israelensis, kLa, Pg/V, LC50, viable spore count

Abstract

Nowadays, forest-extracted wood cellulose still predominantly serves as raw material for pulp and paper manufacture in Indonesia. Consequently, the deforestation rate has alarmingly increased. The purpose of this research is to study the use of mixed microbial cellulose pulp from nata de cassava and pulp from empty oil palm fruit bunch (EOPFB) for paper manufacture. In this research, pulp of nata de cassava’s microbial cellulose was mixed with EOPFB pulp at various proportions. Additives (i.e. 2% alum, 2.5% tapioca starch, and 5% kaolin) were added to such mixture. Sheet forming without additives was made as a control. Addition of microbial cellulose tends to increase the physical and strength properties of paper and decrease the capability to absorb water significantly. The mixture of pulp of empty oil palm fruit bunch and microbial cellulose from nata de cassava has a potency to substitute wood pulp for paper manufacture.

Abstract

ABSTRACTPoly-hydroxyalkanoates (PHA) were blended in solution with Polyoxyetilene-(20)-sorbitan monolaurate (Tween20). In presence of Tween20 component, it caused some polymer interaction between PHA and Tween20 component. Shifting of density, tensile strength and elongation at break was observed for PHA/Tween20 blend. Improvement in elongation at break was drastic in case of PHA blend with 5% Tween20. The addition of Tween20 can reduce PHA melting point and degree of crystallinity. The amount of crystalline was lower for PHA/Tween20 blend than PHA without Tween20 component. FTIR analysis proved that the alteration of PHA characteristic was caused by hydrogen bonding between PHA and Tween20 molecules. The highest blending performance based on its flexibility was showed by PHA blend with 5% Tween20.Keywords : Bioplastic, polyhydroxyalkanoates, Ralstonia eutropha, Tween20
