Abstract

ABSTRACTRed ginger is one kind of ginger, which is usually used for modern and traditional herb medicine. Fresh red ginger is easily damage; therefore preservation technology is needed. Red ginger preserved by drying or being fermented as pickle. Red ginger powder is another preservation method that has advantages in better transportation and storage purposes. 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.Red ginger is dried in 1m3 cabinet dryer at 55 OC and 30 % relative humidity, under that circumstances, the red ginger‘s moisture content follows the equation Y = 123.47e-0.0203x; as the result red ginger must be dried for approximately 135 minutes to get 7.41 % of moisture content. The constant period ended at 30th minute of drying process. This point also known as critical moisture content of red ginger’s drying process, at this point red ginger has 37.00 % of moisture content.Red ginger powder without filler has the longest shelf life. At 25 OC it has 629 days of shelf life. Shelf life at 30 OC is 544 days, 343 days for shelf life at 40 OC, 1500 days for shelf life at 10 OC and 593 days of shelf life at 28 OC. Red ginger powder’s shelf life will generally decrease with filler’s addition.Keyword : ……………..

Abstract

ABSTRACTModification of the Asni’s mathematical model was adopted to predict the shelf life of red chilli seeds,  based on the first order of kinetics in the deterioration process of seed viability.  Application of the modified model to storage experiments of red chilli seeds at different moisture contents of 14.3 % and above, the shelf life of the seeds was only one month or less,  at moisture contents of  6.5 to 10.6 %  was 4 to 26 months, while at very low moisture  contents was more than 26 months. From this research it was found that the safe moisture content in room temperature storage of  red chilli seeds required moisture content in the region of secondary bound water (between 4.0 – 12 % wet basis). For very long shelf life  the seeds could be stored in the region of primary bound water ( bellow 4.0 % moisture), but along with the risk of  hard seed phenomenon.

Abstract

ABSTRACTRoot tissue of Solanum nigrum L A4 strain was found to adsorb heavy metal especially Zinc (Zn).  Compared with activated carbon used as adsorbent on industrial waste water treatment process, the adsorption by root tissue of Solanum nigrum L was higher. The adsorption of Solanum nigrum L was represented by Langmuir and Freundlich isotherms equation. Ground powder of Solanum nigrum L was immobilized by natrium alginate for a practical use.  Zinc  concentration adsorbed by immobilized Solanum nigrum L were higher than ground powder form.  The adsorption capacity shows the capacity of the adsorbent used.  It was calculated through dividing adsorbat (mg) with the weight of the adsorbent (gr).  Even the concentration of zinc  adsorbed by immobilized beads was higher, the adsorption capacity of ground powder form of Solanum nigrum L was higher then immobilized beads.  It might be caused by the natrium alginate which also adsorbed zinc and formed higher weight of adsorbent, and implies that polymer used for immobilization creates a binding coated on the Solanum nigrum L  ground powder surface.Key words : adsorption, plant tissue, zinc, immobilization

Abstract

ABSTRACTRuminant production is impeded by lack of forage and roughage.  This experiment tried to make use the ample supply of palm press fiber (PPF) as the  sources of roughage. The first experiment was conducted  to evaluate effect of urea for ammoniation on digestibility and fermentability of PPF, on the level of 2, 4 and 6% urea, respectively. The result of trial 1 indicated that digestibility and fermentability of ammoniated PPF was higher than that of  the control.  The best digestibility and fermentability was attainable by ammoniation with 6% urea.  This  best result was then used in trial 2 by supplementation  of  0, 5, 10, 15, and 20% cassava leaves based on dry matter feed (source of branched chain amino acids (BCAA) on syntesis of microbial protein, digestibility and fermentability. The experiment diet composed of 50% PPF and 50% concentrate. Supplementation of cassava leaves increased the digestibility, fermentability and syntesis of microbial protein. Supplementation of 15 % cassava leaves increase syntesis of  microbial protein to 30.64 mg/l/ hour. The result showed that ammoniated PPF with supplementation 15% DM cassava leaves was better in digestibility and syntesis microbial protein.Key words : cassava leaves, palm press fiber, ammoniation,  ruminant production

Abstract

ABSTRACTSludge generated from waste water treatment process of pulp and paper mill is a potential source of material to produce compost. It still contains a cellulose and mineral substances needed for composting. For composting in this experiment, the sludge was mixed with the rice husk in the ratio of 95:5, 85:15, and 75:25 (w/w) and added with Trichoderma viride in the concentration of 0.2% and 0.4% (v/w). The composting followed the China and Windrow methods. During composting the temperature reached 55oC after 12 days and C/N ratio decreased according to quadratic regression. In respect of the final C/N ratio obtained, composting using the China method showed a shorter time than by the Windrow method. The ratio of sludge and rice husk of  95:5 and concentration of Trichoderma viride 0.4% (w/v) resulted the best compost product for both methods. C/N ratio of 25 could be achieved in 34 days for China method and 39 days for Windrow method. The compost product fulfills the commercial compost standard. Key words : sludge, composting, windrow method, china method
