The development of science and technology in agriculture, has been instrumental in increasing the production of various agricultural commodities. But climate change is also uncertain world led to decreased agricultural productivity. World energy crisis resulted in higher prices of agricultural commodities due to competition between food and energy are higher. Efforts to utilize biomass (agricultural products) has started a lot of research, not only as raw material for bioenergy, but also in an attempt to exploit agro-products into valuable economic products, and realize clean production in agro-industry.

Abstract

ABSTRACTThe objective of this research is to analyse the effect of the starch suspension temperature and the 1-butanol volume as complexing agent to the characteristic of amylose of sago starch fraction. In the fractionation process, the yield of amylose fraction increased in line with  the increasing of starch suspension temperature and increasing of 1-butanol volume as complexing agent.  The different condition of fractionation process produced  amylose fraction which was different in molecular weight distribution (fraction-1 and fraction-2).  The functional properties of amylose fraction with  fraction-2 dominant (solubility, swelling power and freeze-thaw stability) are relatively lower compared to the amylose fraction with  fraction-1 dominant.  On the other hand  the clarity and oil retention capacity (ORC) value are relatively higher.Key words : fractionation, sago starch, amylose fraction, functional properties

Abstract

ABSTRACTThe oil palm trunks become a waste from the rejuvenation of the oil palm plantation. The extraction of the oil palm trunk can produce about 4.7% of starch.  The starch extracted was characterized for its physical and chemical properties and compared to the commercial starch of sago and tapioca. The starch of oil palm contains fat (0.37%), ash (0.68%), fiber (1.78%) which were higher than those of sago and tapioca.  However, the amylose content (28.76%) of the oil palm starch was lower. The gelatinization temperature of oil palm starch (77oC) was similar with that of sago, but it was higher than that of tapioca.  The whitish degree (83.02%) and the paste clearance (15.4% T) of the oil palm’s starch were lower than sago’s and tapioca’s.  Based on the amylograph analysis, the oil palm starch was categorized normal and had final viscosity which was higher than commercial starch. It was indicated that oil palm starch was easily to be retrograded and suggested to be  used as an adhesive material.Key words: oil palm trunk starch, physico-chemical properties

Abstract

ABSTRACTRed ginger is one kind of gingers, which is usually used for modern and traditional herb medicine. Fresh red ginger is easily damage; therefore preservation technology is needed. Red ginger is preserved by drying or being fermented as pickle. Red ginger powder is another preservation method that has advantages ie. easy to  transport, store and use. Red ginger powder is the main product used for base or supplement material in drug industry. Furthermore it is not only consumed in powder form but also being extracted to yield an oleoresin and essential oil. During the storage period, the quality of red ginger powder can decrease; therefore shelf life dating of red ginger powder is needed.Based on decreasing of its color (chroma), red ginger powder without filler has the longest shelf life. The shelf life of red ginger powder without filler are  629 days (32.8 months of shelf life) at 25 oC, 544 days (18.1 months) at 30 oC, and 343 days(11.4 months) at 40 oC. Red ginger powder’s shelf life will decrease because of sucrose or dextrose monohydrate addition.Keywords : ginger powder,  shelf life, lightness

Abstract

ABSTRACTMyristicin (C11H12O3) is one of the most important constituents of the nutmeg oil.  Myristicin is toxic and hallucinogenic agent in nutmeg and mace.  Isolation of myristicin can be carried out by steam distillation.  The objective of this research was to extract myristicin from nutmeg oil by steam distillation. Nutmeg oil was distilled at  pressure 15 mmHg, 145, 150 and 155oC for concentration.  The highest myristicin content in oil fraction was 70.10% with concentration 786.99 g/l obtained by distillation at 145oC.  Under this operating condition the yield of oil fraction was 6.72%.  Isolation myristicin by steam distillation method was conducted at atmospheric pressure for 2, 2.5 and 3 hours.  The highest myristicin content in oil fraction was 84.44% with concentration 916.25 g/l which was obtained by steam distillation of 3 hours.Key words : Myristicaceae, myristicin, nutmeg oil, steam distillation

Abstract

ABSTRACTTechnology to produce Aloe vera powder has  been implemented in Aloe vera centre (AVC), Pontianak, West Kalimantan in pilot-plant scale. Based on chemical analysis and biological activity test, Aloe vera powder can be used to formulate cosmetic, food and pharmaceutical products such as lotion, shampo, soap, food supplement, sun burn cream and healing. Based on AVC technology pilot plant, research on designing an integrated Aloe vera powder industry has been conducted with system approach which the aim was to establish its decision supporting system and design engineering of Aloe vera industry in optimum  scale. The research finding indicated that the application of system was able to synthesize ideas of interdiciplines; therefore it would improve the effectiveness of decision-making integratively. The research produced decision-supporting system model of integrated Aloe vera powder industry that accommodate the needs of stakeholders and should be effectively used by the decision makers facing dynamic change and information development. The research also produced process engineering flow diagram and layout of Aloe vera industry plant at economic optimum capacity.  These models includes the evaluation of the best Aloe vera product, the best location of industry,  material and energy balance, choise of specification of apparatus. This model can analyze the feasiability of Aloe vera powder industry in various capacities and optimize the economic capacity scale. To prevent farmer from decreasing Aloe vera price, this model designed  win-win solution cost between industry and farmer to keep sustainability of industry and increasing farmers income. This model can also calculate the farm to save industry in raw material sustainability. Financial analysis with case study in Aloe vera Centre, Pontianak, West Kalimantan, shows that optimum capacity 25 ton powder/year, raw material 1852 ton Aloe vera/year (minimum farm 26 ha) with yield 1,35%, production periode 8 hours/day, 240 days/year and feasible with Pay Back Period 4,04 years, Break Even Point 13,568 ton powder/year, Net B/C 2,00, IRR 36,96% and feasible.. Win-win solution price of Aloe vera Rp.1100,-/kg Aloe vera. Sensitivity analysis shows that limit of decreasing  product price  26.43% from normal price and limit of increasing raw material price Rp.3400/kg Aloe vera (normal price Rp.1100,-). Keywords : design, model, decision supporting system,  integrated aloevera powder industry.
