The formulation of microcapsule of 2,4-dichlorophenoxy acetate acid using biopolymer polycaprolactone as a matrix using solvent evaporation method has been carried out. The microcapsule formula was used three types with the ratio 2:1, 1:1, 1:2 between 2,4-dichlorophenoxy acetate acid and polycaprolactone. Distribution particle test was used calibrated microscope. Active substance release test was detected by UV-Vis spectrophotometer. Polycaprolactone can be used as the matrix polymer for slow release preparations and influence to the release of active substance 2,4-dichlorophenoxyacetate acid. Result showed that recovery test of the formula-2 containing 86.5 % higher than formula-1, 84.5% and formula-3 78.2%. Model of the kinetics of the release active substance from microcapsule which correlation coefficient close to one is formula-1 which follow zero order kinetics.

Produksi Bioplastik Poli (3-Hidroksibutirat) (P(3HB)) Secara Proses Fermentasi Menggunakan Bakteri Bacillus brevis FAAC-20801 Dari Minyak Kelapa Sawit Sebagai Sumber Karbon Krisyanella Krisyanella; Mimi Susanti; Akmal Djamaan

The production of bioplastic P(3HB) with fermentation process by Bacillus brevis FAAC-20801 from palm oil as carbon has been carried out. The fermentation process was conducted throug at pH 7, 37oC and agitation rate of 200 rpm for 60 hours. The characterization of the bioplastic production was based on cell growth, P(3HB) content and P(3HB) percentage. Results showed that the optimum time was 48 hours, with fermentation biomassa 277 mg, P(3HB) content of 7.2 mg/ 20 mg biomassa (36 % b/b). Fermentation process in bioreactor produced P(3HB) higher than in rotary shaker incubator.

The optimation of production process of bioplastic poly (3 - hidroxybutirat) (P(3HB) fermentation by Bacillus sp FAAC 20801 bacteria, using straw as carbon source has been carried out. Detection of P(3HB) produced using gas chromatography. The highest glucosa level obtain by using H2SO4 5% for hidrolisis. From 46800 mg straw (glucosa concentration 200 mg/mL) produce 5379 mg biomassa and 0.058 mg P(3HB) ; from 83400 mg straw (glucosa concentration 400 mg/mL) produce 5011 mg biomassa and 0.124 mg P(3HB) ; from 142800 mg straw (glucosa concentration 600 mg/mL) produce 3992 mg biomassa and 2.309 mg P(3HB).

Research about exploiting of straw as component of ethanol as fermentation based on difference able of inoculums consentration and fermentation time has been studied. Straw utilized in this research is result of agriculture raffle from rice plant type IR 46, which taken away from rice field the district of Lubuk Minturun, Padang. The first, stage hydrolysis was done to straw using H2SO4 P 1% with various time 30, 60, 120, 180 and 240 minute and determined glucose produced for each sample. The fermentation of ethanol by using Saccharomyces cereviceae bacterium were conducted at temperature 30ºC with speed 100 rpm. Sampling was taking every 6 hours (6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66). The inoculum’s grade level is variation by 1, 2, 3% v/v. Results showed that the optimum hydrolysis time wich mark by highest glucose rate is minute 240 with grade level 0.7765 %. The highest ethanol grade of which can be yielded with inoculum 1% was 0.02066 % v/v at yeast inoculum 2 % was of 0.02549 % v/v and yeast inoculum 3 % was of 0. 07804 % v/v.

The antimicrobial activity of endophytes microbe that symbiosis with mangosteen had been carried out. There were 12 fungal’s isolates and 14 bacterial’s isolates had been isolated from cortex, lief, and pericarp of Garcinia mangostana L. Each fungal’s isolates were fermented in Soybean Extract Broth liquid medium for 1 week at on a rotary shaker incubator at a 25-270 C and 90 rpm speed. Each bacterial’s isolates were fermented in water corn soaked medium for 24 hours on a rotary shaker incubator at 300C and 120 rpm speed. Fermented fungal’s and bacterial’s were tested their antimicrobial’s activity against Staphylococcus aureus, Escherichia coli and Candida albicans with agar diffusion methode. The result showed that J-G1 (Candida sp) and J-T1 (Candida sp) were fungal’s isolates that ware active against Escherichia coli with inhibition diameter 10 mm. J-H1 (Curvularis sp), J-G2 (Candida sp), J-T1 (Candida sp) were fungal’s isolates that were active against Staphylococcus aureus with inhibition diameter 9 mm, 11 mm and 13 mm respectively. B-T2 (Klebsiella sp)and B-K51 (Bacillus sp1) were bacterial’s isolates that were active againts Escherichia coli with inhibition diameter 13 mm and 18 mm respectively. B-H (Bacillus sp2), B-G (Bacillus sp2), B-P1 (Bacillus sp1), B-K101(Bacillus sp1) and B-K102 (Bacillus sp1) were bacterial’s isolates that were active againts Staphylococcus aureus with inhibition diameter 11 mm, 14 mm, 15 mm, 16 mm and 15 mm respectively.

The formulation of leaf´s murbey ethanol extract´s toothpaste and its activities against dental plaque´s bacteries had been done. Pre test showed the leaf´s murbey ethanol extracts at 4% of concentration gave an optimal diameter of inhibition against dental plague. Based that fact, this research would have made 3 formulas at toothpaste from leaf´s murbey extract at 1%, 2%, and 4% of concentration. All of formulas would have wade with the same base of toothpaste. All of formulas would be characterized of pharmaceutic´s properties and antibacteria´s activities, that would be compared with toothpaste “S” and “P” as a standard. The result shawed all formulas gave a good characteristic of pharmaceutic properties. F3 had gave a good diameter of inhibition, that was 21.875 mm, where as the “S” and “P” of toothpaste had gave a diameter of inhibition respectively 23.875 mm and 22.75mm. There was a significant difference of inhibition´s diameter of all formulas at 0.05 level of confidence.

The study on 2,4-Dichlorophenoxyacetic acid (2,4-D) microencapsulation by solvent evaporation method using polycaprolactone (PCL) as a polimer has been done. The monitored of data how the effect release of substance active toward coated during 480 minutes. From the result of disolution gave rapid disolution of microcapsulation 2,4-D higher at formula 2 rather than formula 1 and 3. This show thickly upholstry of PCL have an effect on to release of substance active. Kinetics method release of substance active of microcapsule 2,4-D following order zero, first order and equation of Higuchi.
