Abstract

The research of pineapple utilization as raw materials of bioethanol production using simultaneous saccharification and fermentation (SSF) method has been done. The purpose of this research was to increase the utilization of pineapple as raw material for bioethanol also to obtain the effect of microbial species used and the length of fermentation on the yield of bioethanol. The treatments conducted were species of microbe and the length of fermentation. The results showed that the treatment of multiple microbial cultures of Aspergillus niger, Saccharomyces cerevisiae, and Zymomonas mobilis (1:1:1) with 24-hour long fermentation produce ethanol yield and the optimal concentration of 50,680 ml/kg and 6.335%.

Abstract

Optimization process of virgin coconut oil (VCO) production to meet the  quality of lulur cosmetics was carried out in the Institute for Industrial Research and Standardization Pontianak. This research aimed to  increase the productivity of pure coconut oil both quantity nor quality that were produced so it can meet the quality characteristics as  raw material of  lulur cosmetic. This research was use coconut and pineapple in a local species as the main raw material and other supporting materials such as VCO and others. There were 2 (two) treatment factor used  namely  A (bromelin extract volume) and B (mixing time). The parameters observed were water content, acid number, saponification  number, and free fatty acid (FFA). Results showed that the treatment without bromelin extract  with 5 minutes mixing time were the best treatment for raw material of lulur cosmetic, with the  water content 0.122%, the free fatty acid 0.062%, the acid number 0.174, and saponification  number 261,21  (the condition for oil as the cosmetic raw material was 0.2% max.).

Abstract

This research was to utilize solid waste of durian (durian skin) into economically valuable products. The purpose of this research was to obtain a decorative paper or art paper which can be used as a wide range of creative products such as photo frames, tissue boxes, pencil boxes and others. The research was carried out by destroying the skin of durian and other materials to form slurry and then molded and dried. Assessment of art paper quality was based on the beauty of its performance because it was display the fibers on the surface of the paper. It has been carried out analysis of gramatur, tear resistance, moisture content and ash content of the paper produced by durian skin. Paper with gramatur value, moisture content, low ash content and high tear resistance was the good quality paper. For gramatur and water content testing, a paper which was given a red ocher dye (D) is a paper that has the lowest value of gramatur and water content, each of 0.0212 g/cm2 and 7.77%. While the ash content and tear resistance testing, colored paper with mangosteen peel 17% (E) has a low ash content (0.056%) and high tear resistance (104 times fold).

Abstract

The research of cookies of bamboo shoots was as functional food carried out to increase the utilization of bamboo shoots that were very potential in West Kalimantan as functional food. The bamboo soot cookies was made from dry processing of luxuriant bamboo shoots to mamboo shoots flour, and the production of bamboo shoots cookies. Results of analysis showed luxuriant bamboo shoots contained thewater 94.4 %, ash 0.28 %, protein 1.6 % fat 4.78%, carbohydrate 0.637 %, rough fibre 2.03%, vitamin C 0,003 %, phosphor 0.120 %, calcium 114 mg/kg, and sodium 27,4 mg/kg. Dry bamboo shoots were produced through the process bleaching with the solution to salt 3% and produced bamboo shoots flour with results efficiency 6,25 % and had the content of the level of water 5,66%, the level of ash 6,44 %, protein 20.9 %, fat 3.64 %, the carbohydrate 17.9 %, rough fibre 3.97%, and vitamin C 0.0021 %. Best bamboo shoots cookies that is to the C treatment variable that was produced from the mixture of bamboo shoots flour: wheat flour: maize flour = 20:60:20. Results of the analysis were based on the standard of the quality of the biscuit (SNI-0-2973-1992) showed that the product that was produced contained the water 4,14%, ash 3.22%, protein 8.95%, fat 16.5%, carbohydrate 37,01%, rough fibre 0.379%, calorie 332,34 cal, and the Executive Board’s metal < 0,040 mg/kg, Cu 1,92 mg/kg, Hg<0,004 mg/kg, as well as Zn 27,1 mg/kg. Bamboo shoots cookies that were produced were categorised as functional food that could help the process of the digestion so as to be estimated could reduce the risk of colon cancer.

Abstract

Orange (Citrus nobilis var. microcarpa) is the main commodities in Pontianak. Production of essential oils from orange peel wastes and its use for soap aromatherapy substance could improve its economic value. This study is aimed to produce the essential oils from orange peel wastes with the highest limonene content by distillation. Its application for aromatherapy soap substance also evaluated. Distillation of essential oils from orange peels was performed at 1000C and 1100C for 4, 5, 6 and 7 hours. The results showed that at 1000C for 7 hours produced the highest limonene content, reach 97.69%. The essential oils color was pale yellow, specific gravity 0.84, refractive index 1.47, solubility in 90% ethanol 1:1 (transparent), acid value 0.143% and ester number 5.37. The aromatherapy soap produced with addition of 3.6% of limonene oils is in accordance with SNI 06-3532-1994 except for water content parameter.

Abstract

Milk is an important food for baby that contains lactose. Normally, a baby could produce lactase enzyme that digest lactose, but in the diarrhea case lactose could not be digested. So, Low Lactose Milk is needed. Low Lactose Milk usually produced from rice or almonds that have low protein. Soybean (Glycine max) is the commodity with rich of protein and also contains raffinose and stachyose, which can lead flatulence. Raffinose and stachyose could be reduced by Rhizopus oryzae at tempe process from lamtoro beans.  So the aim in this research is to know the optimum time of soybean fermentation with R. oryzae to reduce stachyiose  and raffinose. The research was done with innoculation of R. oryzae isolate in the soybeans fermentation for 72 hours. N index, raffinose and stachyose level was tested. The result shows that optimum fermentation time is 48 hour and using 5% skim milk as filler.

Abstract

Fucoidan is a complex polysaccharide compounds found in brown algae. Fucoidan exhibits various biological properties for disease prevention. There are various methods used to extract fucoidan from brown algae, such as using ethanol, acetone, HCl and microwave. This research aims to extract and characterize fucoidan from Sargassum sp. using simple methods with the variables on extracting solutions, temperature and time of extraction. Extraction solution used were water and HCl. Ttemperature used was 50°C, 70°C and 100°C  using 1, 2 and 4 hours. The result showed that the highest extraction yield was obtained from the extraction by water with 100°C and 4 hours of extraction. Fucoidan extracted by water has molecular weight of 57.77 kDa and 2.71 kDa, while fucoidan extracted by HCl has molecular weight of 46.43 kDa and 3.38 kDa. The proportion of high molecular weight fucoidan extracted by water was 52.24% compared with HCl was 44.10%.
