To obtain an environmentally sound control method of looper caterpillar (Hyposidra talaca, Ectropis bhurmitra, Biston suppressaria) as an alternative to reduce the use of chemical insecticide in tea estate, a study to evaluate the effect of the formulation of L. camara-based insecticide against looper caterpillar on tea plant has been conducted at Pasir Sarongge Experimental Garden (1,100 m asl), Cianjur, West Java. The trial was arranged in a randomized complete block design with six treatments, replicated four times. The treatments comprised: Formulation WP of L. camara-based insecticide with two doses, 1,5 kg/ha and 3,0 kg/ha; Formulation EC of L. camara-based insecticide with two doses, 1,5 l/ha and 3,0 l/ha; Standard chemical insecticide, Decis 25 EC (deltaÂmetrin) at 300 m/ha; and control. The L. camara-based insecticide and chemical insecticide were sprayed three times with one week interval, one day after plucking. The intensity of looper caterpillar attack was measured every week after spraying at the time of plucking. Results showed that all of the L. camara-based insecticide formulation treatments were effective against tea-looper caterpillar. The effectiveness in reducing the intensity of looper caterpillar attack were not significantly different each others, and were comparable to the standard chemical insecticide. The effectiveness level were relatively high, with the average of 45,25%. Based on these results it could be concluded that both formulation of WP and EC of Â L. camara-based insecticide could be used for controlling tea-looper caterpillar at lower dose, i.e. 1,5 kg/ha and 1,5 l/ha for the formulation of WP and EC, respectively.

Drought season with rainfall <100 mm/month for more than two months cause tea plant growth disturbed, reduction in leaf proÂduction, and death of plant. Nitrogen was the macro essential nutrient needed for vegetative growth and was important for building the cell, include protein, DNA, and RNA. Nitrogen was related on proline content to support the drought tolerance in plant. The nitrogen reÂquirement on tea plantation can be fulfilled by anorganic, organic, and biofertilizer. This study was aimed at determining effect of indigenous and exogeneous endophythic bacteria effecÂtiveness on productivity and nitrogen content on soil and tea plant. This research was carried out at the Block A7 Gambung, Research Intitute for Tea and Cinchona. The study was conducÂted during drought season (June to September 2013). The experimental design was randomize blocked design with factorial arrangement and three levels of each factor: i.e. 1. anorganic nitrogen dose (N): a. 100% N dose; b. 75% N dose; c. 50% N dose, 2. endophytic bacteria (E); a. control (without); b. indigenous (DtG7-5); c. exogenous (Acinetobacter sp). The result showed that the indigenous and exogenous endophytic bacteria could be maintained the leaf production and significantly different on drought season, i.e. on 3rd, 4th, and 6th plucking. The highest leaf production increasing depend on before applied the treatment was the combined of endophitic bacteria and 100% anorganic fertilizer. All of the treatment has not significantly different on N-total of soil and N content of plant. The applied of indigenous and also exogenous endophytic bacteria was proÂduced the average of nitrogen content on soil around 10-13% higher than the control treatÂment (only anorganic fertilizer applied) and the nitrogen content on plant was lower 1-2% than control treatment (only anorganic fertilizer applied).

The good performance of extension activities and openness tea market opporÂtunities has been playing an important role in accelerate the successful of tea farmer groups. The successful of tea farmer groups itself can be seen from the functioning of the units in farmer group activities, namely unit of study, unit of production, unit of collaboration, and unit of business. This study are aimed to determine the successful of tea farmer groups in carrying out its functions and to determine the effect of extension performance and tea market opportunities to the successful of the tea farmer groups at Sodonghilir District, Tasikmalaya Regency. This study used mixed method approach with sequential explanantory strategy that analyzed by using path analysis. The sampling method that used in this study was proportional random sampling with 56 farmers or 25% of the sample population (225 farmers). The results show that the highest successful of tea farmer groups at Sodonghilir District on unit of production, unit of collaboration, and unit of business were still low. Extension performance and tea market opportunitiest significant influenced directly to the successful of tea farmer groups. The better extension performance and greater tea market opporÂtunities, so the higher the successful of farmer groups. The efforts to increase the successful of tea farmer groups can be done by increasing the institutional capacity of tea smallholders, extension performance, and disclosure opporÂtunities of policy and tea market.Â

In Indonesia has been found 11 cinchona species but only two species recognized as an economically important Cinchona succirubra known as resistant plant to root disease while Cinchona ledgeriana quinine high content. To put together those two characters from mostly through grafting it took twelve months. Micrografting is one of the propagation techniques through tissue culture. Micrografting has already been used in wide spread for plants propagation either only for research or as mass product. Hopefully, the use of micrografting to obtain cinchona propagation would be short more or less 10 months and provide plants as mass production economically. The result showed that micro grafting at V shape could be used as the propagation method on cinchona species besides bud multiplication through tissue culture. MS medium is the best medium for cinchona micrografting. If there is no IBA on rooting media, there is no root formation from the plants. The increasing of IBA from 1 up to 4 mg/l in media, will increase also the number of rooting plants.different plant material as scion and stock and different concentrarions (0,1,2,3,4 mg/l) of IBA gives the significantly different respons on rooting formation. The increasing of IBA on media will increase the number of rooting plants also. The highest rooting formation are found on medium with 3 danÂ 4 mg/LÂ IBA. The combination between C. ledgeriana-C. succirubra, C. ledgeriana-C.ledgeriana, C. succrirubra-C.succirubra gives significantly difference on the growth dan development of root. The use of C. ledgeriana as a root stock doesnât showed good rooting formation. The combination between CSA/QRC205 gives the highest number of leaves result compare wth others combination on as much as 9,8. The first stage of acclimatization on culture room with temperature 25-270C and followed by acclimatization on plastics house covered with paranet 70%. In general in vitro planlet cinchona from micrografting growing well. By the end of observation (8 weeks) growing percentage reach 90%.Â Â

The effectiveness application of compound fertilizer NPK (27%:6%:10%) to increase Â tea shoots had been tested in Experimental Garden of Research Institute for Tea and Cinchona Gambung, Bandung, West Java, from January 2006 to March 2007. ExperiÂmental design used was randomized block design with 6 treatments with five replication. The plot sizes were 20 x 20 m = 400 m2/plot. The tea clone tesÂted was GMB 7. The appliÂcation of compound fertilizer NPK (27%:6%:10%) were twice a year (50%-50%) and conventional fertlization were 4 times a year (20%-30%-20%-30%). The composition ofÂ treatment was as follows: (A) 500 kg, (B) 600 kg, (C) 700 kg, (D) 800 kg/ha/year, and (E) conventional fertilizer recommended dosage of the Research InstituteÂ for Tea and Cinchona Gambung (480 kg urea + 357 kg ZA + 260 kg SP 36 + 300 kg KCl + 278 kgÂ kieserit/ha/year), and (F) control (no fertilizer treatment). ParametersÂ observed were: 1. soil and leaf analysis at before and after treatment, 2. weighting the potential and the yield components each time of plucking, and 3. technoeconomic analysis. The results showed that: statistical analysis of the components as well as potential yield, and nutrient analysis (N, P, K, Mg and Zn) of the mother leaves of GMB 7 clones and the soil demonÂstrated the significantly differences among the treatments of all the various doses of compound fertilizer NPK and conventional fertilizer application to control (no fertilizer treatment). Meanwhile, there were no significantly differences among the result of Â the doses of compound fertilizer NPK, to the conventional fertilizer applications. FurtherÂmore, dose of compound fertilizer NPK (27%:6%:10%) for producÂtive tea plant was recommendated at 700 kg/ha rate and was equivalent to 189 kg N/ha/year or 63% of the dose of conventional fertilizer, but could provide equivalent result to conventional fertilizer application, and not only could save the buying cost of conventional fertilizerÂ (urea, ZA, TSP/SP-36, KCl / MOP and kieserit) but also the cost of application cost in the field.

Enzymes, especially pectinase, plays an important role in the processing of tea that determines the quality and the color appearance of black tea. The main obstacle encountered in the application of enzymes in food processing in general, and in particular in the processing of black tea is the price of commercial enzyme that are still very expenÂsive, because it is still imported. Indonesia has a high fungal diversitythat is potential as producer of commercial pectinase enzyme. To reduce the cost of production, fermentation was done using solid waste of plantation that rich of pectin content such as cocoa pod husk that has not been optimally utilized. The research aimed to develop the production technology for pectinase enzymes of fungi through solid substrate fermentation for applications in the processing of CTC black tea. Research includes the isolation and selection of local superior fungi producing enzymes pectinase, optimizaÂtion of enzyme production by fungi isolates were selected through a solid substrate fermenÂtation using cocoa pod husk waste, production optimization included optimization of fermenÂtation time and substrate composition, enzyme extraction of fermented substrate, and appliÂcation of pectinase enzyme extracts in the processing of CTC black tea and sensory test of fermented tea. The results showed that it has been obtained isolates of Aspergillus niger on Pectinase Screening Agar Medium (PSAM) which was capable of producing pectinase enzyme on growing media of mix cocoa pod husk and rice bran with additional of enrichment media. The optimum conditions of pectinase production was obtained in the composition of cacao pod husk: rice bran (80:20 w/w) plus enrichment media, the incubation time of 9 days, which produced pectinase activity of 125 U/mL. Applications of pectinase on enzymatic oxidation of CTC tea proved that it was capable of raising the quality of the tea flavor, though the tea gradedid not change.
