Abstract

Tea is a popular drink in the world. Types of tea which is rarely used is white tea. Besides consumed as a beverage, white tea can also be used in extracted form. White tea extract contains polyphenols compound, particularly catechins that can be used as an antibacterial. One of white tea extract uses that can be added to production of olive oil transparent soap based. This study aimed to determine the process of transparent soap production, looking for the best concentration of white tea extract, determine the characteristic and quality of transparent soap, and look for the extend of inhibition zone of Staphylococcus aureus in transparent soap. The treatments given in this research were the concentration of white tea extract 1% (w / v) with the addition of A (control soap) = 0% (w / w), B = 0,5% (w / w), C = 1,0% (w / w), and D = 1,5% (w / w) of 300 grams of soap bases. Transparent soap characteristics observed were physical-chemical properties, antibacterial and organoleptic test. The analysis showed that all transparent soap baths complied the SNI 06-3532-1994 requirements of solid soap, except the water content and evaporated substance and the amount of fatty acids. The best result of this research was soap with treatment B (with 0,5% (w/w) extract addition), which was chosen based on organoleptic test (such as aroma, hardness and foam quantity) and Indonesian National Standard (SNI) qualities of solid soap with best result in unsaponified fraction test, hardness, and foam stability.

Abstract

Theaflavin (TF) is a product of catechin oxidation that give contribution to golden yellow color, brightness, briskness of black tea and has a potential as natural antioxidant activity. TF has a higher superoxide radical capture rate than EGCG (Epigallocatechin gallate). The study was to synthesize TF components in the form of extracts that have high antioxidants. Materials used in this research is bud+3 leaves from RITC clone (GMB 7). The research were caried out used 15 liters of tea leaves pulp per treatment, fermentation using fermentor with 15 L/min, 20 L/min and 25 L/min airflow treatment, separation of TF from thearubigin (TR) used 2.5% NaHCO3, and isolation of TF from impurity compounds used silica gel column with ethyl acetate/hexane as eluent, and DPPH (1,1-diphenyl-2-picryl hydrazyl) for antioxidant activity. The result showed that TF synthesis of fresh tea leaf catechin at water-air rate of 25 liters/minute could produced TF extract and yield TF purity extract with 1.01% and 39.15% in dry weight respectively after isolation by silica gel column. Antioxidant activity by DPPH from TF extract showed the smallest value of EC50 is 12.16 mg/L at 150 mg dose and its activity increased with the addition of concentration of TF extract.

Abstract

Tea is a plant that benefits for health. The growth of tea plant was influenced by several factors, including superior clones and nutrient availability in soil. One of the most important macro nutrients is potassium. However, the availability of potassium is low because of retention on the soil. One of the methode for absorbed by plant was used Potassium Solubilizing Bacteria (PSB) with its organic acid function. The aim of the study was to explore and determine the density of colonies (DC) and the potential of Tea Indigenous PSB. Inoculum source from tea rhizosphere and rhizoplan of GMB 7, GMB 9 and TRI 2024 clones. The experimental design used was completely randomized design with six treatments and four replications, i.e. : GMB 7 Rhizosphere; GMB 7 Rhizoplan; GMB 9 Rhizosphere; GMB 9 Rhizoplan; TRI 2024 Rhizosphere; and TRI 2024 Rhizoplan. Ten isolates with the highest halozone was tested by the Dissolution Index (DI) of the PSB. The result showed that the highest DC was GMB 9 rhizoplan by 10.9 x 105 CFU/g and the lowest was TRI 2024 rhizoplant by 3.1 x 105 CFU/g. The DC on GMB clones series showed that rhizoplan was 14,29% higher than rhizosphere. There is no significant difference of DI for PSB colonies from all clones. From that clones, we were obtained 10 isolat that have the highest halozone, that were 2 isolates from rhizosphere and 8 isolates from rhizoplan. The average of DI rhizosphere isolates was 119,9% higher than rhizoplan.

Abstract

Efforts to improve the productivity of tea needed new high yielding clones were obtained from the cross and easily propagated vegetatively. Preliminary testing of the clones  needs to be done to determine the growth of cuttings and rooting properties of tea clones from hybridization which are selected by potential production. This study used a Randomized Complate Block Design with three replications. The treatments consist of 14 clones from crosses and GMB 7 as clone comparison. The data is analyzed by using ANOVA and Scott Knott test with the level of 5%. The observations are intended to look at the growth of roots and shoots by dismantling seedling in polybag predetermined randomly at each observation. The results showed that the clones tested had good growth with a low mortality rate, and easily propagated vegetatively. The S / R ratio also showed shoot growth more faster than the growth of root. This character is advantageous because the most appropriate selection criteria for planting in the field.
