Coffee seeds are generally difficult to germinate with long dormancy time, this is an important aspect in this study to the response and use of hormones as stimulants grow for the seedling process of liberica coffee beans to quickly germinate. This study used two factors, it is hormone and concentration as the basic concept for coffee seed with giving treatment a mechanism soaked using hormones with different concentrations. Hormones as growth stimulants (ZPT) as the basis of the germination stimulation process. Hormones used for this study are the hormones GA3 / Giberelin, IAA / Auksin and BAP/Cytokinin. Hormonal solutions are of course not independent of concentration or normality in the solution, therefore the study applies 3 levels of concentrations including 250ppm, 500ppm and 750ppm as a combination of hormones and normality to test the viability of germination, plant heights, stem diameters, wet weights of the plant, and root length as the observation parameter. Furthermore, the value of the observation will be analyzed by using anova (LSD) 5% confidence level. After 5% of treatment result (LSD), the best effect was obtained from the treatment of combination of GA3 hormone with 250ppm concentration of 1.5273 (cm) and this treatment was the best for GA3 hormone with plant height is 2,627 (cm).

Porang plants ( Amorphophallus onchophyllus ) is a shrub ( herb ) that the leaves grow armpit bulbil as a breeding tool. In addition to using bulbil porang can also reproduce by using bulbs and seeds. Bulbs to be harvest as result because it has glucomanan compounds that high economic value. Currently there porang tuber production sold to employers to be exported abroad in the form of chips filled with a gathering of farmers iles - iles that grows wild in the environment and forestry plantations. Intensive cultivation efforts should be supported by the availability of seedlings. Therefore, it needs to be study with seedlings originating from sources other than the tubers, ie with bulbil. The purpose of the study is 1) Knowing the effect of combined treatment of sitokinin (CPPU) concentration and dose of NPK fertilizer on growth and yield porang 2) Knowing sitokinin (CPPU) concentration effective in improving plant growth of porang and 3) Knowing the optimum dose of NPK fertilizer on plant growth porang. This experiment is a factorial experiment with 2 (two) factors which are arranged in a completely randomized design (CRD) and repeated 4 times. The first factor is the concentration CPPU (K), which consists of : K0 = Without CPPU (control), CPPU 5 ppm = K1, K2 = CPPU 10 ppm, 15 ppm CPPU = K3 and K4 = CPPU 20 ppm. While the second factor is the dose of fertilizer N , P and K (P) consisting of : P1 = dose of NPK fertilizers (Urea 15 g, SP36 7.5 g, KCl 7.5 g), P2 = dose of NPK fertilizers (Urea 20 g , SP36 10 g, 10 g KCl) and P3 = dose of NPK fertilizers (Urea 25 g, SP36 12.5 g, 12.5 g KCl). Observations were made on growth and development, as well as crop yields porang, which consists of: plant height (cm), leaf canopy width (cm), stem diameter (cm), number of bulbil, bulb diameter (cm) and weight of tubers per plant. The results showed that: 1) There was no significant interaction of all variables observation, 2) Concentration CPPU very significant effect on canopy leaf width and number of bulbil. Concentration CPPU 20 ppm produces a wide canopy of leaves and number of bulbil highest with increased width of the leaf canopy by 38 % and increase in number of bulbil by 87% compared with controls. 3) Fertilizer doses very significant effect on canopy leaf width and number of bulbil. Dose of NPK fertilizer 25 g urea, 12.5 g SP36 and 12.5 g KCL (P3), shows the results of the leaf canopy width and number of bulbil highest with increased width of the leaf canopy by 34% and increase of number bulbil by 67% compared with fertilizer treatment 15 g of urea, 7.5 g SP-36 and 7.5 g KCL (P1).

One of the most constraint factors among corn farmers, which can cause enormous losses to corn farmers in Indonesia is the downy mildew disease. Losses due to this disease can achieve a loss of up to 90%, controlling of plant pathogens is currently still based on the use of synthetic pesticides, whereas the use of synthetic pesticides on a continuous basis can cause various negative impacts. The negative impact of the use of synthetic pesticides is large enough for the environment one of them is the killing of non-target microorganisms such as fungi and antagonistic bacteria located on the ground especially in the rhizosphere of plants.Therefore need to be followed up research on antagonistic fungus/non parasite for plants derived from rooting corn plant, as a control against pathogen infection. The diversity of microorganisms is important in the balanciation of soil ecosystems. This research aimed to find out the relationship of diversity of microorganisms with the level of maize crop disease, and to know the difference the diversity of rhizosphere microorganisms in corn plantations on different land. The relationship between the diversity of microorganisms and the level of maize crop disease attacks the greater the diversity of microorganisms in the corn crop area, the lower the incidence rate of gallbladder disease. Conversely, the lower the number of microorganisms diversity in the corn crop area will be the higher the rate of bouts disease. The highest diversity index was found in Caruban Village of 1.0983, while the lowest diversity index was found in Sumbersari village of 0,5505, and the lowest level of seizure disease was found in Caruban Village 0.96%, while the highest rate of disease was in Desa Sumbersari by 50%.

To control pest Crocidolomia pavonana in cabbage plants are still based on chemical and mechanical control. The methode is considered ineffective because excessive use of chemicals has a negative effect on the comodity and the environment. The application of plant protection technology using Biological Control Agents (BCA) is one of the solutions given. One of them is entomopathogenic nematode (EPN). The advantage possessed by EPN is the symbiosis with the symbiont bacteria that secretes toxins so that it can immobilize the host quickly. Based on this, a study was conducted to determine the pathogenicity of symbionic bacteria against Crocidolomia pavonana larvae, so that they could be developed as bioentomopathogenic in the Integrated Pest Control concept. The pathogenicity test on Crocidolomia pavonana larvae was carried out using 4 treatments placed in a Completely Randomized Design (CRD) with each treatment repeated 6 times. The results showed that in the three days of observation, the four bacterial isolates had the same ability to kill Crocidolomia pavonana larvae with the highest percentage of 100% and the lowest 88.9%. Thus the four isolates can be used as an alternative in controlling Crocidolomia pavonana larvae.

Sugarcane is a plant which only grow in tropical. Plant pests and plant diseases in cultivation have never been separated. One of the important pests of sugarcane is uret root destroyers (Lepidiota stigma). The pests can reduce crop yields by 50%. One of the best alternatives for uret pest control which can be safety and environmentally friendly by using biological agents. The biological agents for pests control has a good potential and prospects because they are host-specific and harmless to human. This study was conducted to determine the effectiveness of Metarhizium anisopliae, Beauveria bassiana and Streptomyces sp.mortality Lepidiota stigma. This study used 3 treatments in a completely randomized design (CRD) with each repeated 9 times. The results showed that for four observations at intervals of seven days of observation. The ability of three biological agents has different varieties in turning off the test insect, this is indicated by the highest mortality percentage of M. anisopliae with total mortality of 88.89%.
