Abstract

The biomass potential of tea plantations such as tea pruning waste, shade tree waste and waste of tea replanting are large enough. Energy derived from biomass is a renewable energy source that environmentally friendly, and it does not cause a negative impact to the environment. Heat exchanger tubeless type can only use fossil fuel. To replace the fuel derived from biomass on the tubeless type of heat exchanger, the furnace must be designed specifically as a substitute for fuel oil burner. This paper provides the result of engineering design of tubeless type heat exchanger of and their performance in a fluidized bed dryer of orthodox black tea. Apart from that, the design suitable also for the green tea drying machines. As a substitute for fuel oil burner, the heat exchanger tubeless type can use waste of tea replanting. The ratio of fire wood was 0.90 kg per kilogram of made tea with 57.9% of the energy efficiency and 46.3% of drying energy efficiency.

Abstract

L-theanine is amino acid contained in tea (Camellia sp.) leaves having ability as relaxation compound. Combination of L-theanine and other compounds produced from fermentation of green tea extract by Kombucha starter generates Kombucha tea with unique taste and better relaxation functional. The concentrate of Kombucha tea as functional drink for relaxation (anti stress) was produced by purification on fermented green te extract through 0.2 µm MF membrane fitted in stirred microfiltration cell (SMFC)  at stirrer rotation speed of 200 rpm and 400 rpm, and pressure of 30 psia. Purification was conducted on 4 grades of Kombucha tea from local green tea extract with rich L-theanine, such as Pekoe, Dewata, Arraca Kiara and Arraca Yabukita as a result of purification by MF module. Kombucha tea produced through fermentation at 1 part of permeate and 1 part of water ratio using Kombucha (5%, v/v) starter riched by sucrose of 10% (w/v) under room temperature for 7 days. Based on the best L-theanine concentration, the result of experiment showed that SMFC at stirrer rotation speed of 400 rpm was able to retain L-theanine in retentate from Kombucha tea of Arraca Kiara, Arraca Yabukita, Dewata, and Pekoe grades, subsequent 29.1, 96,53, 44.62 and 71.54% (w/v) from prior to process as feed. In other words, optimization condition was reached at Kombucha tea of Arraca Yabukita grade producing retentate or concentrate of Kom­bucha tea with L-theanine, total poly­phenol, reducing sugar, total solids, and total of titratable acids of 2.5605% (w/w), 3.4314% (w/w), 14 mg/mL, 4.8947% (w/w), and 0.2195% (v/v) respectively.

Abstract

Case of business portfolio for self financing of  Indonesia Research Institute for Tea and Cinchona is very interesting to study. In general, the research institute of tea in tea producing countries in the world receive finan­cing from the funds cess or levy or Government Budget. In PPTK, is a very rare case because the status of PPTK is a corporate. The unit of research and development as a cost center to produce innovations to increase the compe­titiveness of national commodity tea as well as Cinchona, should be financed from the portfolio business unit. Therefore, portfolio business strategies are needed in order to play optimally the role of  PPTK accordance with its mandate. The method used to determine the position of corporate is SWOT analysis especially  method to the value of  IFE and EFE. Furthermore, to determine the position and strategize potfolio business units use Boston Consulting Group (BCG) matrix. The results showed that the value of its IFE and EFE (-0.14; 0.11) is in quadrant II that  position of stability/ratio­nalization, which led to the Selective Main­tenance Strategy. BCG matrix of the mapping results, the majority of the business portfolio in PPTK be in the Quetion Mark. One business unit shoul be divested is Stevia estate due to its position of the Dog business group. Meanwhile, the business unit of  Cash Cow group are unit of garden and black tea factory and tea experiment garden of Simalungun. In order to better self financing of PPTK, several business units in the group of Question Mark with specific strategies should be push to move into the star groups, namely (1) unit of superior plant material production of tea and cinchona; (2) unit of garden and green tea factory; (3) laboratory services and expertise; and (4) unit of production of white tea and tea packaging.

Abstract

Transparent soap was made using high quality materials that beneficial for skin health and beauty. The main ingredient of the transparent soap was virgin coconut oil (VCO), with the addition of white tea extract which was able to increase the benefits of transparent soap. This study aimed to create formulation of the transparent soap, to find the addition of the white tea extracts to produce transparent soap and to study the characteristics of the transparent soap after the addition of white tea extracts. The treatments in this study were the addition of white tea extracts A = 0% (w / w), B = 0.5% (w / w, C = 1.0% (w / w and D = 1.5% (w / w). Observations on the transparent soap were including chemical properties, physical properties of soap, antibacterial and organoleptic test. The results of the analysis showed that all transparent soap formulas met the requirements of solid soap SNI 06-3532-1994, except for the total fatty acid. The formula of transparent soap with treatment B (addition of white tea extract 0.5% w / v) was the best product with organoleptic test results reached 43.34%. The analysis results of those soap were 11.47% of water content and evaporating substances, 37.97% of total fatty acid, 0.519% of free fatty acid, 2.24% of unsaponified fraction, pH value of 9, hardness 0.0077 mm/g/sec, the foam stability of 76.88% and the activity of antibacterial inhibition diameter of 10.7 mm, respectively. This technology could be applied in the production of transparent soap with the addition of white tea extract and to be developed into some industrial scale.

Abstract

Climate change has been influencing rainfall pattern so that it would be necessary to see the impact of that changed on tea plantation. The experimental area coverage lowland (600 m asl), midland (800-1000m asl) and highland (>1.000 m asl) tea plantation and each altituted represented by three tea estate in West Java. The rainfall data collected since 2005 up to 2014 from each estate and water deficit has been count through the method develop by Wijaya (1996). The results showed that the rainfall pattern has been changed by La-Nina and El-Nino during 2005-2014 in tea estate either in lowland, midland or highland in the last decade. The climate change caused  rainfall decreasing and increasing on dry month (the rainfall < 100 mm). Eventhough on 2009 there is an significantly increasing of the rainfall but after 2009 until 2014, the rainfall tend to decrease. After El-Nino on late 2009 and early 2010, lowland tea estate on Subang Regency facing water deficit until 5 months with R (defisit water index) far below 1 even there is no El Nino. The tea plantation at midland area (Cianjur Regency) facing 5 months water deficit per year, but the R index close to 1. While in highland tea plantation (Bandung Regency), the water deficit only happend on certain month on certain year although there is a month with zero rainfall. Water deficit could be happend because of runoff on soil surface stimulate by low ability of soil to keep the water.

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.
