The objective of this research was to eva-luate the effect of biofertilizer on the abundance of nitrogen fixing bacteria and growth of cin-chona plants (Cinchona ledgeriana Moens) clones Cib.5. The research was conducted at the Research Institute for Tea and Cinchona, Gambung, Bandung, from May 2011 until June 2011. A randomized block design was used with five treatments and five replication. Application of five concentration of biofertilizer were per-formed. Concentrations were: 0, 2, 4, 6, and 8 cc/l of water. The results indicated that the application of biofertilizer gave the higher total bacterial population compared to the treatment without biofertilizer, but showed no significant effect on growth of Cinchona plants. Concen-tration of biofertilizer 8 cc/l gave the higher total bacterial population of nitrogen fixing.

Effect of prunning technique and foliar fertilizer application had been conducted to improve yield of pecco in the Research Institute for Tea and Cinchona experiment station, Gambung, Indonesia with altitude of 1.350 m above sea level, and with andysol soil type. The experiment was held from July to October 2015 in tea production field area containing 480 plants. The clone was GMB 7and was in the fourth prunning year, interval of plucking pecco was seven days. The experiment was arranged in a randomized block design with four treatments, replicated six times. Foliar fertilizer application was performed following every plucking. The results indicated that breaking apical dominance of tea short by 5 cmâ10 cm of prunning above plucking table combined with foliar fertilizer application of N 1% and ZnSo4 2% + 0,1% of humic acid, could increase weight of pecco per plot in the first nine weeks of the prunning. This treatment was better than the other three. But the percentage of pecco shoots was low, lower than 50%, the weight of one pecco was also very low 0,7 g, indicating that the treatment of harvesting pecco in the fourth prunning year was not recomended to be practiced in improving yield of pecco.

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 (9.531Â 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.

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.

Chemical control method of blister blight disease (Exobasidium vexans Massee) on tea could inflict various negative impacts. In order to obtain an environmentally sound control method of blister blight disease, a field trial has been conducted to know the effectiveness of various non-chemical control methods on blister blight disease. The trial was carried out at Ciliwung Tea Plantation (1.400 m asl), Bogor, West Java, designed in a randomized complete block, with eight treatments and three replications. The treatments tested comprised: the application of an antagonistic fungus (Verticillium sp.) on two level of doses, 2 and 3 kg/ha; the application of nutrient (mollases 2% + urea 1%); the application of the combination of the antagonistic fungus and nutrient (Verticillium sp. 2 kg/ha + mollases 2% + urea 1%); the application of compost tea with and without aeration system; the application of copper-chemical fungicide as standard treatment; and control. All of the treatments were applied by spraying on tea bushes infected by blister blight disease, and the parameter observed was blister blight disease intensity, which was formulated in percentage of disease intensity index (DII). The results showed that in heavy-attack condition (DII higher than 50%), only the treatments of compost tea application which were effective in suppressing the intensity of blister blight disease. Meanwhile, other treatments of non-chemical control methods could not suppress the disease intensity, even the copper-chemical fungicide as a standard treatment was no longer effective too.Â The results also showed that the use of aeration system in making compost tea could increase the effectiveness of compost tea in controlling blister blight disease. The effectiveness level of aerated compost tea (42.9%) was higher than non-aerated compost tea (29.5%).

An in-vitro experiment to evaluate total nitrogen content of soil of tea plantation area included with indigenous and exogenous AzotoÂbacter sp have been conducted in the Biology and Soil Biotechnology Laboratory, PadjaÂdjaran University. A completely randomized design with 11 treatments and three repliÂcations was used. The treatments were: A (neÂgative control); B (positive control); C (A. Kedelai II); D (A. vinelandii); E (A. N.D.9.3); F (A. Padi); G (VI-1); H (II-1); I (V-2); J (I-1); and K (III-2). Size of microbe inoculated popuÂlation for each treatment was 1,2 x 1011 CFU/ml. One percent dose was used for steÂrilized soil originated from the tea plantation area. After five days of incubation period reÂvealed that II-1 Azotobacter sp produced very significantly different in total nitrogen proÂduction than the other Azotobacter sp, i.e. 0,8532%. Orthogonal comparisons indicated that indigenous Azotobacter sp had the capacity of nitrogen fixation 7,67% higher than that the capacity of nitrogen fixation of exogenous Azotobacter sp for growth on Andisol soil of tea plantation area with pH of 4,5-5,6. Although, Azotobacter sp is very rarely found in soil with low pH (high acidity), this phenomena indiÂcating that an active biofertilizer of indigenous Azotobacter sp is present in tea plantation area.
