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

Indonesian tea market share tend to decrease due to the weakness of competitive advantage of Indonesian tea. The weakness of Indonesian tea competitiveness should be cla-rified by supply chain. Primary data collected from survey as well as expert meeting. Analysis method applied in this research is supply chain analysis. Research results showed that in term of Indonesia tea production of 165.070 tons in 2006, tea volume to be processed to down-stream products for domestic consumption is around 62.776 tons. The rest is for export pur-poses consists of bulk black tea export (92.763 tons) as well as bulk green tea export (9.531 tons). This condition relatively stable up to 2013 due to Indonesia tea import volume around 20,000 ton disburse to domestic con-sumption (55%) as well as re-export purposes (45%). The most of smallholder tea production (63%) come to jasmine tea processors located in Central Java. Farm gate price of green leaf is around 15,8% of consumer price of jasmine tea. Total margin of supply chain from tea farmers to jasmine tea consumers is around Rp22.100,00/kg of made tea consists of Rp13.121,00/kg made tea (50% of total margin) as cost margin and Rp8.979,00/kg made tea (34,1%) as profit margin. To remedy supply chain of smallholder tea should remedy factors affecting supply chain. Priority factors should be improved i.e. (1) quality of tea in each chain, (2) availability as well as assistancy to credit access, and (3) conducive of trade policies.

Abstract

Glyphosate, which has been documented as a contaminant in tea, promotes the proliferation of human breast cancer cells (MCF-7). Tea, on the other hand, includes various antioxidants, including epigallocatechin gallate (EGCG), which may protect against cancer cell proliferation. The purpose of this research is to determine the preventive effect of concentrated brewed green tea on MCF-7 development caused by glyphosate. The glyphosate concentration that promotes MCF-7 development was determined using a serial concentration of glyphosate. Glyphosate concentrations of up to 64 mg/L were shown to have no effect on MCF-7 cell proliferation. Concentrated brewed tea and EGCG 200 mg/L have the potential to suppress MCF-7 cell proliferation in the presence of glyphosate up to 512 mg/L. The combination of glyphosate and concentrated brewed tea or EGCG protects against glyphosate toxicity via altering the expression of tumor suppressor protein (p53).
