Publisher : Balai Besar Industri Agro

Fannel (Foeniculum Vulgare Mill) has been well known by indonesia people. Fannel seeds have strong pleasant odour because of essential oil. The major essential oil constituents of fannel were anethole and limonene, with more than 80% of the total oil. The other chemical consituents were- pinene, myrcene, y-terpinene, fenchone, estragole and fenchyl acetate. To increase the use of fannel oil, anethole consituent can be converted to its derivations by oxydation, acetylation, reduction, esterification and alcylation processes. Fennel seeds are used as a flavoring for goods and beverages and the essential oil from seed and plant has flavoring, cosmetic and pharmacuetical uses. The tendency in consumming medicine from natural plant material source, cause in the increasing use fennel as medicine raw material, especially the simplified usage which was used in traditional medicine.

A study to substitute sweet potato flour for wheat flour dough has been conducted using two type of wheat flour and various percentage of substitution. To test the degree of substitution, the characteristics of dough were measured using Brabender farinograph and Brabender Extensograph. Measurement of rheological properties using farinograph showed that the dough made of 60% sweet potato flour with hard wheat and those of 40% sweet potato flour with medium wheat cannot be done. Viscoelasticity of dough from 40% or more sweet potato flour with hard or medium wheat cannot be measured using Extensograph.

The objective of this research is to study the effect of natural antioxidant such as clove and sesame seed on the reaction rate of coconut oil oxidation. The experimental procedure used the randomized block design factorial using two variables. The treatment chosen consists of coconut oil with clove antioxidant, coconut oil with sesame seed antioxidant, coconut oil with sesame seed plus clove antioxidant which each dosage 200 ppm and finally coconut oil without antioxidant (control). Those samples were analyzed at periodic intervals for oxidative deterioration. The parameter analysis consists of the perioxide number, free fatty acid, iod number,moisture content and oil clearness. The result indicate that the natural antioxidants (clove and sesame seed) are capable of preventing oxidative deterioration. Natural antioxidants give a very significant result on coconut oil quality, in the following order : coconut oil with clove antioxidant, coconut oil with sesame seed antioxidant, coconut oil with sesame seed plus clove antioxidant with the constant of reaction rate 0.15, 0.12 and 0.09.

The study on effect of bamboo variety and pyrolization through direct combustion using a fire brick klin model wquiped with a condenser to produce charcoal and vinegar has been carried out. The observation was conducted on the time and temperature profile of pyrolization process, yield of charcoal and its collected vinegar. The resulted charcoal and its liquor were subjected to further analysis, i.e. ash content, volatile matter at 950'C, fixed carbon content, and calorific value for the charcoal and the pH, organic subtances profile for the liquor. The study revealed that the yield of charcoal was varied from the lowest 8. 07 % (wb) of Bamboo Petung and the highest of 20.81% (wb)i.e., of Bamboo Andong. The ash content of charcoal was varied from 5.01 to 6.8% (wb). The volatile matter at 950'C was varied from 17.47 to 33.96% (wb) whereas the fixed carbon content was ranged from 5237 to 6637 cal/g. The electrica! conductivity was ranged from 8 - >9 , degree of crystallite between 10,45 and 14,51 % and surface area was ranged from 41,9 to 118,5 cm/g. it is also revealed yhat the yield of the Bamboo vinegar was varied from 6,52 - 17,26 % (wb) with pH varied from 3.75 to 4.01. The content of organic compounds found in liquor was varied i.e,. 19 compounds found in the liquor of Bamboo Andong, with dominant compound of tricyclo(2.2.2.1.0(2,6)heptene, 1,7 -dimetyhl-7-(4-methyl-3-penthyl)-(CAS)Si which comprised to 29.69 %, 29 compounds in liquor of Bamboo Petung with dominant compound of Acetic acid (CAS) Ethylic acid which comprised to 40.66 %, 13 compounds in liquor of Bamboo Ampel with domonant compounds of 2,6,10,14,18,22-Tetracosahexaene, 2,6,10,15,19,23,-hexamethyl- (CAS) Squ which comprised to 73.38 %; 39 compounds in liquor of bamboo Tali with dominant compound of cyclohexanon, 2-Isobutyl which comprised to 18.64% and 64 compounds was detected in liqour of bamboo Hitam domonant compounds of 2,3-dihydro-Ben zofuran which comprised to 11.53 %
