Exploration and Selection of Rhizobacteria that Inhibit Phytophthora capsici in vitro. Phytophthora capsici, a seed borne and the soil borne fungal pathogen is the cause of phytophthora blight on chili. The disease is difficult to control because of the resistant varieties unavailability in Indonesia. The aimed was to obtain isolates of rhizobacteria which has the ability to inhibit P. capsici in vitro. Rhizobacteria exploration was conducted in the chili production center in East Java (Malang, Batu, and Kediri) and West Java (Bogor). In one location, chili plant that had symptoms of phytophthora blight disease and a healthy plant next to it were chosen as samples to isolate P. capsici and the rhizobacteria. The rhizobacteria were isolated on NA, TSA, and TSAP (TSA with heated sample). Samples of diseased plants were used in isolation of P. capsici on V8 agar. The inhibition and compatibility of the rhizobacteria to inhibit P. capsici in vitro were tested by dual culture method. In this experiment, it was obtained 252 isolates of rhizobacteria and one isolate of P. capsici. Isolates of rhizobacteria with high to medium inhibition were E1, E3C2, and F2B1 respectively. All three isolates were then combined and tested against P. capsici in vitro. The highest inhibition was indicated by four isolate and combination of isolates, which were E1 isolate (58%), the combination of E1 + E3C2 isolates (58%), E1 + F2B1 (60%) and E1 + E3C2 + F2B1 (58 %).

ABSTRACTIncreased of plant productivity in field determined by the use of quality seed from improved variety. The purpose of this research was to study the effect of frequency and volume of phyllosphere biological agents by foliar spray on rice plant infected by Xanthomonas oryzae pv. oryzae (Xoo) in improving plant growth, production of rice seed, and controlling bacterial leaf blight (BLB). This research was conducted at Seed Health Laboratory, Department of Agronomy and Horticulture, Bogor Agricultural University, and Muara Experimental Field, Rice Research Institute, March through September 2014. The experiment was conducted using a randomized complete block design with two factors, and replicates as blocks. The first factor was five levels of frequency of spraying with biological agents: P0 = control, P1 = Xoo seed inoculated then invigorated with biomatriconditioning, P2 = Xoo inoculated seed, then biomatriconditioned, and the plants were sprayed with phyllosphere biological agents F112 once, P3 = as P2, and the plants were sprayed with F112 twice, and P4 = as P2, and the plants were sprayed with F112 three times. The second factor was three levels of spray volume: i.e., 300, 400, and 500 L ha-1. Result of this experiment revealed that biomatriconditioning with rhizobacteria P. diminuta A6 and B. subtilis 5/B improved field emergence and seedling dry weight. Seeds applied with biomatriconditioning then followed by foliar spray with phyllosphere bacteria F112 at 40, 60, and 80 days after transplanting effectively reduced severity of BLB, increased plant dry weight and seed yield. All treatments increased yield as compared to untreated control. Volume of foliar application showed no significant difference, therefore, the lowest volume of 300 L ha-1 was recommended. Keywords: Bacillus subtilis 5/B, biomatriconditioning, Pseudomonas diminuta A6, Xanthomonas oryzae pv. oryzae

Seed vigor test to evaluate seed quality requires a faster, more precise, and simple method. Radicle emergence (RE) is a rapid vigor testing method that has been validated by International Rules for Seed Testing since 2014 on maize seeds. The objective of this research was to develop an RE method test as a rapid vigor test on soybean seeds. The experiments were conducted at the Seed Storage and Testing Laboratory, and Sawah Baru Experimental Station, IPB University, Bogor, from November 2018 to March 2019. The RE experiment was arranged in a randomized completely block design (RCBD) with repeated measurement in a split-plot design, using ten varieties as the main-plot and seven times of observation as the sub-plot. The RCBD with one factor (variety) were used for laboratory and field experiments. Determination of observation time for radicle emergence test was done from 36 through 48 hours after sowing with 2 hours interval. Results of the RE test were then correlated with other vigor tests, normal germination, and seedling vigor in the field. The results showed that the RE test on soybean seeds of ten varieties with different vigor levels (classified by vigor index) using top of paper germinating method at 25 ± 2 °C and observed after 42 hours ± 15 minutes was closely correlated and could predict the normal germination, vigor index, speed of germination, mean germination time, field emergence, and mean emergence time. Therefore, RE can be used as a rapid vigor test for soybean seeds. Keywords: field emergence, mean emergence time, mean germination time, normal germination percentage

Tuwel Village is the village with the most population and automatically the amount of organic waste donated by the community also increases. Organic waste is exacerbated by the absence of a Temporary Disposal Site in the village. Environmental pollution that occurs in the form of an unpleasant odor arises as a result of spoilage of organic material from waste. Maggot is one of the potential organisms that can break down organic waste. The village community does not have knowledge about maggot cultivation which can provide benefits. The purpose of this program is to inform the public about organic waste management and increase the economic value of the community through waste management activities. The method used is the socialization and designation of maggot metamorphosis. Both activities were carried out on two different days with 3 different places. The result of this program is that the community understands the life cycle of maggot, the procedures for cultivating maggot, the benefits in cultivating maggot, a type of organic waste that can be processed by maggot. Organic waste is useful as a medium for maggot cultivation. During the activity, participants actively listened and asked questions in the question and answer session. Keywords: cultivation, maggot, organic waste, socialization

Luwijawa Village is a village located in Jatinegara District, Tegal Regency, Central Java Province. The village which has an area of 257,285 ha, the majority of its residents work as farmers. Agriculture carried out is rice farming with rice and corn as the main crops, as well as plantation crops such as coffee and durian. Villagers still use chemical fertilizer as a nutrient provider for plants, as well as the problem of rubbish that is still burned or thrown away by residents. The activity of sorting waste and training on composting was carried out to educate the public, especially PKK women, on how to manage waste to compost fertilizer. The socialization is done by the lecture method. The speaker explained the material using a power point and continued with video playback. Participants can ask questions after the socialization activities have been completed. Socialization activities and compost making training were carried out on different days. Compost making training is conducted with residents from organic waste. Organic waste obtained from residents' kitchen waste is cut to pieces and mixed with bioactivators (EM- 4). The ingredients that have been mixed are then put into a bucket and tightly closed so that no air enters, this is done to maximize the work of the bioactivator in the fermentation process. Compost making training activities took place well, there were quite a lot of participants, with relatively high enthusiasm. This is evidenced by the many questions asked by participants in the series of activities. Participants have been able to distinguish organic and inorganic waste, and have the desire to make their own compost with materials available in the surrounding environment.
