This study aims to find out the interaction effect of application combination of ectomycorrhizal fungi and Tc-Jjr-02 Trichoderma harzianum isolate on initial growth of clove seed (Syzygium aromaticum L.). The experiment was arranged factorially by using Completely Randomized Design; first factor: application of ectomycorrhizal fungi (without and with ectomycorrhiza), while the second factor: the application of Trichoderma fungi (without and with T. harzianum), the experiment was repeated 4 times. The variables observed were: number of leaves, leaf area, stem diameter, root length, root weight, wet weight and dried straw, and intensity of mycorrhiza infection. Data analysis using 5% ANNOVA continued with HSD test. The results showed that there was a significant interaction effect between the combination of ectomycorrhizal fungi and Trichoderma application on the number and extent of leaf and the intensity of root infection of clove seedlings. The combination of ectomycorrhizal fungi and T. harzianum isolates can be used for the production of healthy clove seedlings.
This study aims to determine the control power of two isolates of Trichoderma obtained from the forest floor soil to the activity of Fusarium oxysporum pathogen causing stem rotation of red chili plant in vitro. The experiment was arranged in complete randomized design using 3 kinds of treatment of Trichoderma sp., T. harzianum isolate and control (without Trichoderma fungi isolate) tested for its antagonistic ability against pathogen; each treatment was repeated 4 times. The observed variable is pathogen inhibition (%). The observational data were analyzed by using variance followed by 5% HSD test to know the difference between treatments. The results showed that T. harzianum (Tc-Jjr-02 isolate) and Trichoderma sp. (Tc-Pjn-01 isolate) were able to inhibit F. oxysporum pathogens respectively 76.9% and 77.1% at 108 hours after inoculation. Both of these Trichoderma fungal isolates can be developed into biocontrol agents for F. oxysporum.

However, because intense state hegemony on every line, include press, literary positioning itself to participate on social problem. Journalistic still i mportant for l iterary development in Indonesia, but its formula has been questioned by literary. Therefore, literary will attract "crowd", by doing sublimation again, by transcend human problems from "crowd" view to human Reality.
Indonesia is estimated to produce as much as 64 million tons of waste every year. This figure is very high because only 7 percent of the total destruction has been managed. Kudus Regency has a policy on waste management, but most people in Kudus Regency do not yet know the policy. This study aims to determine the implementation of waste management policies in Kudus Regency. This type of research is qualitative research, with four informants. The research instrument used an interview guide, a recording device, and a camera. The analysis method uses a thematic content analysis. Based on the results of the research, it is known that the local government has not carried out mass socialization of waste management policies to the community so that many people from various groups do not know this regulation. The implementation of waste management in the Kudus Regency is also constrained by a limited budget and waste processing equipment. In also besides, monitoring and evaluation activities are also only a formality because there is no follow-up to the monitoring and evaluation activities every year.
The average pakcoy mustard production in Indonesia is still quite low at 20 tons / ha. This study aims to determine the effect of goat manure and nitrogen fertilizer (N) on the growth and production of mustard greens. This research was carried out in Plaosan village, Wonoayu sub-district, Sidoarjo regency, using factorial completely randomized design with 2 factors, factor 1: without goat manure (control) (P0), goat manure 100 grams / polybag (P1 ), 200 gram goat manure / polybag (P2). Factor 2: giving nitrogen at 7 hst (K1), giving nitrogen at 14 hst (K2), giving nitrogen at 21 hst (K3). Of the two factors, 9 treatment combinations were repeated and repeated 3 times so that 27 experimental units were obtained. The results showed that goat manure significantly affected plant height, number of leaves and wet weight. However, when giving nitrogen (N) there was no significant difference in each treatment, while there was interaction between goat manure and nitrogen (N) fertilization time on the wet weight of mustard pakcoy plants with the best treatment in K2P2 with an average of 231,8.
