Penelitian ini bertujuan untuk melihat perbedaan rendemen dan karakteristik fisikokimia pati buah sukun yang berasal dari buah sukun masa panen 1 bulan (MP1) dan 2 bulan (MP2). Pati sukun diperoleh dengan cara dekantasi dan pengeringan. Evaluasi karakteristik fisikokimia serbuk pati meliputi pengukuran kadar amilosa dan amilopektin, organoleptis, pH, bentuk, indeks kompresibilitas, densitas dan laju alir. Rendemen pati sukun yang diperoleh adalah 10,62% (MP1) dan 12,29% (MP2). Kadar amilosa dan amilopektin adalah 4,087% dan 81,637% (MP1) serta 10,213% dan 85,673% (MP2). Nilai pH pati untuk MP1 dan MP2 sama yaitu 3,99. Granula pati memiliki hilus berdasarkan pengamatan mikroskopik. Organoleptis pati MP1 adalah tidak berbau, tidak berasa berwarna putih dan memiliki bentuk serbuk halus sedangkan pati MP2 adalah berbau khas buah sukun, tidak berasa, putih kecoklatan, dan bentuk serbuk agak kasar. Indeks kompresibilitas pati sukun adalah 65,77% (MP1) dan 62,09% (MP2). Nilai bulk density (g/mL) sebesar 0,34 (MP1) dan 0,42 (MP2), sedangkan nilai tapped density (g/mL) sebesar 0,57 (MP1) dan 0,68 (MP2). Kedua pati tidak memiliki laju alir maupun sudut istirahat. Analisis independent sample t-test (?=0,05) menunjukkan bahwa kadar amilopektin, pH, dan indeks kompresibilitas tidak memiliki perbedaan yang signifikan, sedangkan kadar amilosa, bulk density, dan tapped density memiliki perbedaan yang signifikan.

Preformulation Study

BACKGROUND: Pugun tano extract had been studied for its effect as hepatoprotector. However, the usage of the plant in the form of extract has a limitation, especially if the extract is consumed by the people due to the unpleasant taste and odour. Then, the extract needs to be transformed into a particular dosage form, such as a capsule. But before the capsule can be produced, a preformulation study of pugun tano extract into a granule mass in capsule need to be evaluated. AIM: The study aimed to formulate the ethanolic extract of pugun tano (Curanga fel-terrae (Lour.) Merr) as granule mass in the capsule dosage form. METHODS: The pugun tano ethanolic extract was formulated in several steps included preparation of dry extract using coating method with polyvinylpyrrolidone (PVP) and granule mass production. The excipients used for the granule mass were lactose granules (made with tapioca starch using wet granulation), corn starch (made with 3 concentrations of 5% (F1), 7.5% (F2) and 10% (F3)), talcum, magnesium stearate, methylparaben, and propylparaben. The granule mass was evaluated for the bulk density, tapped density, inter-particle porosity, Carr’s index, Hausner ratio, angle of repose, and flowability. RESULTS: The results showed that all of the formulae passed the requirement of the preformulation test. The bulk density of the granule mass was 0.79 – 0.86 g/ml; the tapped density was 0.88 – 0.90 g/ml; the inter-particle porosity was 0.03 – 0.14; the Carr’s index was 2.71 – 11.94%; the Hausner ratio was 1.09-1.12; the angle of repose was 26.10 – 28.90°; and the flowing time was 5.97 – 6.63 seconds. All of the formulae showed good flowability and free-flowing properties. CONCLUSION: It is concluded that the obtained formula

The herbal medicine Nilavembu Kudineer is very effective in viral fevers. The study was effort to prepare a Nilavembu Kudineerherbal capsule from Nilavembu Kudineer churnam. The task of this work is, to detainment of active biomolecules and ensure their biological activity. The Nilavembu Kudineerchurnamwas extracted by ethanol and water solvents, then the extract was dried. The resultant dried extract powder was screened by various chemical and microbiological tests for to ensure the potency.  The results confirms that both the extract haveactive biomolecules and possess their activity. Based on the microbiological activity NVK water extract was comparatively better than the ethanol using extract powder. The dried NVK water extract powder capsules complies with standards of capsule pre and post filling parameters such as angle of repose, bulk density, tapped density, carr’s index and hausner’s ratio. The filled NVK capsule complies the post filling evaluations of weight variation, disintegration. In future stability, dosage titrations and more number of microbial test need to conduct for their effectiveness of the formulation.

Objective: In the present study, efforts were taken to develop fast disintegrating tablets of Cinitapride hydrogen tartrate, is a gastro-prokinetic agent and antiulcer agent with an objective to achieve rapid disintegration, and further improving the bioavailability of the drug. Also, to resolve the swallowing problems (Dysphasia) in pediatric, geriatric patients by rapid disintegration in saliva and improve the patient compliance.Methods: Fast disintegrating tablets were prepared by direct compression method using superdisintegrants like crospovidone (CP), croscarmellose sodium (CCS), sodium starch glycolate (SSG) and combination of super-disintegrants in different concentrations. The prepared formulations were evaluated for the pre-compression parameters like bulk density, tapped density, Carr’s compressibility, Hausner’s ratio and angle of repose. The prepared batches of fast disintegrating tablets of Cinitapride hydrogen tartarate were evaluated for hardness, weight variation, thickness, friability, drug content, disintegration time, wetting time, water absorption ratio, and in vitro dissolution profile.Results: Bulk density and tapped density were found in the range of 0.412–0.432 g/cc and 0.507–0.528 g/cc respectively. In all formulations, tablet weight and thickness were within mean±9.5% and mean±5% respectively. Wetting time values lie between 19.76 to 39.53 sec. Water absorption ratio ranged from 57.30 to 78.82 %. The in vitro disintegration time for all the 12 formulations varied from 17.43 to 38.61 seconds. Formulation F8 which contained crosspovidone have recorded drug release 96.94±0.47% at the end of 30 min.Conclusion: The formulation containing crospovidone (F8) showed better performance in terms of disintegration time and drug release when compared to other formulations.

Kraft Cooking

Alkali charge is one of the most relevant variables in the continuous kraft cooking process. The white liquor mass flow rate can be determined by analyzing the chip bulk density fed to the process. At the mills, the total time for this analysis usually is greater than the residence time in the digester. This can lead to an increasing error in the mass of white liquor added relative to the specified alkali charge. This paper proposes a new approach using the Box-Jenkins methodology to develop a dynamic model for predicting chip bulk density. Industrial data were gathered on 1948 observations over a period of 12 months from a Kamyr continuous digester at a bleached eucalyptus kraft pulp mill in Brazil. Autoregressive integrated moving average (ARIMA) models were evaluated according to different statistical decision criteria, leading to the choice of ARIMA (2,0,2) as the best forecasting model, which was validated against a new dataset gathered during 2 months of operations. A combination of predictors has shown more accurate results compared to those obtained by laboratory analysis, allowing a reduction of around 25% of the chip bulk density error to the alkali addition amount.
