Abstract

Pandanus conoideus (buah merah or tawi) is exclusively grown in Papua island and its neighbor areas, and indigenous people have been consuming it as functional food for thousand years. We have reported safety and anti-tumor effects of Buah Merah extract oil (S.B.M) in experimental animals. However, mutagenicity or genotoxicity of S.B.M has not been evaluated. We carried out mutagenetic evaluation of S.B.M by in vitro Ames test using salmonella typhimurium  TA98, TA100, TA1535 and TA1537 and escherichia coli WR2uvrA with or withou the activation of S9 mixture. Concentrations used for this test were 313-500ug/plate. The results show that there is no increase in revertant colonies, suggesting that S.B.M has no mutagenic activities under the conditions of this study.

Abstract

Heat treatment is one of the important factors in refining castor oil since it was able to coagulate amino acid so that thefat could be easily extracted. The heat treatment conducted were roasting, steaming, and drying. It was conducted before pressing of castor seed. Meanwhile refining castor oil consist of cleaning, grading, drying, pressing, deguming, sentrifusing mixing, bleaching and filter screening (vacuum), washing and quality testing. Pressing of castor kernel was conducted with 50 tons hydrolics press and screw press. Refined castor oil treatment with oven temperature 60 degree celcius for 1 hour showed the higest yield from the other treatment and also the clearer colour. Various concentration and combinationof oxidator was used to produce modified castor oil from refined castor oil. Oxidator used were H2O2 (3% and 5%), KMnO4 (3% and 5%). The best result oxidized castor oil was processed from refined castor oil and oxidator H2O2 3% with 1:5 comparison of volume.

Abstract

Methyl ricinoleate was produced by methanolysis process from castor oil using KOH and NaOH as catalysts. The esterification process was carried out at the temperature of 30 derajat and 70 derajat celcius for 1, 2, and 3 hrs respectively. The product was analyses using GC for the esterification process. The iod value saponification value, and acid number were also analysed. Potassium hydroxide gave higher result in comparison to sodium hydroxide as catalyst for the process duration of 3 hrs. The specific gravity of the product ranged from 0.8903 to 0.9608 and the refractive index was between 1.3810 and 1.4500.

Abstract

Tanaman belimbing (Averrhoa carambola) memiliki potensi farmakologis, antara lain sebagai senyawa antimikroba. Kapang endofit isolat A 1.1 yang diisolasi dari ranting tanaman belimbing, diuji potensinya sebagai antibakteri terhadap Bacillus subtilis, Staphylococcus aureus dan Eschericia coli. Uji antibakteri dilakukan dengan metoda difusi cakram. Analisis GC-MS dilakukan terhadap ekstrak etil asetat kapang endofit A 1.1 untuk identifikasi komponen kimianya. Hasil uji antibakteri menunjukkan bahwa ekstrak etil asetat dan ekstrak kloroform mampu menghambat pertumbuhan bakteri uji. Ekstrak etil asetat mempunyai aktivitas DDH (7,5 mm) lebih besar dibanding ekstrak kloroform (6,10 mm) terhadap B. subtilis. Hasil analisis GC-MS menunjukkan bahwa ekstrak etil asetat kapang endofit A 1.1 mengandung 17 komponen kimia. Komponen utamanya adalah 1-Octadecene, 1-Dococene dan 1-Hexadecene.

Abstract

Nowadays, the use of natural plant source insecticides in one of the best chosen due to its characteristic, which of safer and easily degradable by nature (biodegradable) compared to synthetic materials. One of plant sources wiich consists of active components for insecticides is neem plant. This study aimed to determine the effect of extraction of active ingredients of neem seeds and leaves by fermentation using Effective Microorganisms (EM4). The Extraction of seed and leaf neem to produce neems active compound was conducted by using Effective Microorganisms. The efficacy test of the neem seed and leaf was conducted by using fermented extract concentrated of 3% and 6% and observed with interval of 2 to 6 days. The formula used in this experiment which A as raw material and B as concentration of Effective Microorganisms are A1 as neem;s seed, A2 as neems leaves; and B as concentration of effective microorganisms which is B1 as 3 %, concentration and B2 as 6 % concentration. The extraction product were evaporated with rotary vacuum evaporator. The extracts obtained were tested their solubility. Azadirachtin were obtained on combination od A1B2 for neem,s seeds for 6 days fermentation period which acquired 1313,23 ppm (61,25 %) of azadirachtin and combination of A2B2 for neem;s leaves which acquired 665,69 ppm (69,17%) of azadirachtin from raw materials. The active compounds were tested their ability as insecticide and showed that 50 ppm of azadirachtin concentration still effective for 14 days evaluation.

Abstract

Effect of distillation time on citronellal content of citronella oil has been studied. Two kinds of raw materials were used, one from old plantation at Rumpin Kabupaten Bogor and the other from Batutulis Kecamatan Kota Bogor Selatan. It is showed that most oil were distilled at the early stage of destillation along with the citronellal component. Grass from Rumpin should be destilled for no longer than two hours to obtain enough oil (yield 94%) and citronellal content not less than 35.5%. The grass from Batutulis produced more oil after two hours distillation  (95%) and the average citronellal content is 49.70%. The grass from Batutulis may be distilled up to 4 hours to gain more or less than 100% oil while the citronellal content still at higher level (48%). Obviously the grass from Batutulis is better than Rumpin.

Abstract

Trans fatty acid from commercial frying oils (coconut oil,palm oil, soybean oil and corn oil) were identified to study the effect of thermal oxidation to trans fatty acid forming.Parameters of oil quality analysis were iod number, free fatty acid, peroxide number, percentage of conugated dienae and conjugated triene, and Thiobarbituric Acid (TBA) value. The analysis of trans fatty acid and composition of oils used gas chromatography with 75 m capillary colomn from Supelco SP-2560. Standardized methodologies used for fatty acid methyl ester, quantification of trans fatty acid and oil quality analysis. Heating treatmenr for thermal oxidation was done from initial temperature 180 C in 0 minute and heating time continued until 30, 60, 90 and 120 minute. Trans fatty acid was identified as C18:2:9c, 12t isomer from palm oil, soybean oil and corn oil.These trans featty acid were presented at 0,02-0,325 before heating process and o,04-9,85 after heating process.Trans fatty acid were formed from their natural cis-isomer as result of the high temperature used. Fatty acid composition of frying oils decreased as effect of thermal oxidation. Based on frying oils quality analysis, thermal oxidation decreased the quality of frying oils. Heating time have corellated with decrease of iod number for all of frying oils. Heating time also correlared with increase of free fatty acid, peroxide number,precentage of conugated diene and TBA value. Trans fatty acid could be from thermall oxidation. Results of oils quality analysis, thermal oxidation decreased oils quality and fatty acid composition.

Abstract

The study on the thermal energy consumption and efficiency in coconut oil processing using HOID technology was conducted to evaluate the performance of the thermal energy efficient fumace. the preliminary comsubtion experimental conducted to examine the thermal capacity of the system, indicated that the system could be used to fry minimum of 2 tons coconut meat per 8 hours operation. The frying capacity of the furnace was influenced significanrtly by the ration of the fresh coconut meat to coconut oil and the amount of coconut oil that should be replaced. The higher the ration will result in the higher of the frying rate. The result of experiment showed that the maximum thermal efficiency of the fumace was around 70% this maximum efficiency could be achieved if the loss of the thermal energy from the system could be made minimally, espencially loss due to the sensible heat in the dry flue gas and loss due to the incomplete combustion of fuel resulting in carbon monoxide in the flue gas. The average thermal efficiency of the system was 54%.
