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

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

Research utilization of liquid smoke from oil palm empty fruit bunches of raw rubber has been made to utilize solid waste from industrial processing of oil palm empty fruit bunches of oil palm so that it becomes economically valuable products. This research has been done by pyrolysis of oil palm empty fruit bunches at a temperature of 400oC for 5, 6, 7 and 8 hours. The results show that the pyrolysis liquid smoke oil palm empty fruit bunches for 8 hours give a high concentration of phenol and acetic acid, respectively 5% and 0.454%. Liquid smoke that has been obtained is used as a coagulant in raw rubber plantation crops of the people residing in the village of Ambawang, Kubu Raya District, West Kalimantan. Results of treatment of liquid smoke on raw rubber  show that the rubber products that have been frozen and dried are superior in terms of color, smell and drying time compared with the treatment of formic acid and water battery which has been added so far on raw rubber by the local rubber farmers.

Abstract

So far, most of West Kalimantan cocoa beans sold raw to collectors in Malaysia at a price that is less competitive, so it was necessary to study the processing of cocoa into chocolate bars with products utilizing palm fat as a fat substitute. The purpose of this study was to determine the effect of the formulation of palm fat and cocoa fat on the physical properties of chocolate bars. The research was conducted by varying the concentration of palm fat to total fat namely 0%, 25%, 50% and 75%. The products were tested on melting point and hedonic. Based on research data it can be concluded that the treatment of palm fat concentrations to total fat by 25% produces chocolate bars with a melting point of 36.0 ° C and preferred by the panelist.

Abstract

Coastal areas of West Kalimantan province are rich with seaweed. To increase its economic value, seaweed could be used as primary materials for organic fertilizer production. This research was conducted to find the optimum combination of seaweeds used for organic fertilizer production using Brassica rapa as test plant on alluvial soils. Most dominant seaweeds found were used for biofertilizer production. Three types of seaweeds used were brown (Phaeophyceae), red (Rhodophyceae), and green (Chlorophyceae). Formulations used were 1:1:1, 1:1:2, 1:2:1, and 2:1:1. The formulation that met the biofertilizer quality conformance was applied on alluvial soils using Brassica rapa as a test plant. Result showed that 2:1:1 and 1:2:1 ratio of brown-red-green seaweed is the best formulation based on most growth parameters observed on Brassica rapa.

Abstract

Cellulase is an important enzyme for industry which can be obtained from cheap tropical agrowastes such as durian peel. West Kalimantan, in particular Pontianak city produces tons of durian peel waste during harvest season each year. This study used durian peel waste as substrates and A. niger to produce cellulase, The aim of this study is to determine the optimum incubation time in producing cellulase under solid state fermentation. Different incubation time (48, 72, 96, 120 and 144 hours) were applied for the production of cellulase. The optimum cellulase production was 120 hours of incubation, giving  protein content of 0.3960% and enzyme activity of 1,069.01 ppm, respectively.
