Liquid smoke is the vinegar of biomass pyrolysis process. Cellulose, hemicelluloses and lignin would be degraded into phenol compounds, carbonyls and organic acids that serves as a flavor enhancer and as an antifungal and antibacterial. The purpose of this study was to determine the chemical components in the liquid smoke from Anyer Banten region. This study is divided into two phases, namely phase pyrolysis of coconut shells at 300oC, 400oC and 500oC, pyrolysis time is 2, 3 and 4 hours, and coconut shell size 6-10 mm, 4-6 mm, and 1.6 - 4 mm. This stage produces dark red liquid, so do the second stage distillations process to obtain a pure liquid smoke. Liquid smoke with the greatest yield was analyzed using gas chromatography mass spectrometry (GCMS) QP.2010S Shimadzu. Based on the results of the study there were 11 chemical components were identified, the largest component is 46.56% acetic acid and phenol at 12.93%.Keywords: Liquid smoke, coconut shell, pyrolysis, acetic acid, phenol

This research aims to determine the indirect influence of fertilizers on the population and diversity of herbivorous insects in sweet corn varieties super sweet. The research was conducted from the month from May to September 2011 in the Pakel , Gelam village, Kelurahan Cipocok Jaya, Kota Serang. Experiments used designed randomized block design (RBD). The data were analyzed by Anova and DMRT 5%. The herbivour diversity analized by Shannon diversity index. Experimental variable is the type of fertilizer, compost siam weed at a dose of 45 tons / ha, with a dose of manure 45 t / ha, and synthetic fertilizer consisting of urea at a dose of 400 kg / ha, SP36 and KCl dose of 150kg/ha dose 150kg / ha and the control of maize without fertilizer. The fourth variable is repeated 6 times. Observations were made every 2 weeks for orders, families and populations of plant-feeding insects (herbivores) by directly counting the insects which at that time was on the plant. The results showed that the type of fertilizer is not directly influenced by the high population of herbivorous insects. Plants are fertilized siam weed compost herbivore species diversity is high, but their population is foreign-low type. While NPK fertilized plants herbivoranya low diversity and population of each type of the highest good in sucking and biting insects pencucuk chewers. Associated herbivorous insects on corn consists of groups biter chewers like grasshoppers (Acrididae) and pencucuk like ticks sucking aphids (Aphididae).Keywords: fertilizer, herbivores, compost, corn, Acrididae, Aphididae

Inheritance of resistance trait to ChiVMV was studied in intraspecific capsicum population derived from a cross between two Capsicum annuum line, PBC495 as a resistance line and ICPN12#4 as a susceptible line. The resistance was assessed by diseased index (DI) and score of absorbance value at  405 nm, two weeks after inoculation. Based on t-test of F1 and F1R, it was concluded that there was no maternal effect. Nil symptoms resembling the resistant parent were identified in the progeny F2, BC1P1 (BC1 to the resistant parent) and BC1P2 (BC1 to the susceptible parent) populations. Segregation of resistance (nil DI and lower absorbance value) and susceptibility in the F2 fitted a 3:1 Mendelian ratio, indicating that resistance were controlled by a single dominant nuclear gene. Nil segregation of the trait in the test crosses in BC1P1 and a 1:1 ratio segregation in BC1P2 also confirmed the 3:1 gene segregating model as found in the F2. Heritability values of the trait were medium to high.Key words : inheritance, resistance, ChiVMV, pepper

UJI KETAHANAN 10 TANAMAN PADI VARIETAS LOKAL BANTEN TERHADAP PENYAKIT HAWAR DAUN BAKTERI (Xanthomonas oryzae pv. oryzae) PADA FASE PERSEMAIAN Sunariah Fany Ali; Dewi Hastuti; Andree Saylendra

Bacterial leaf blight disease is an economically important disease for the growth of rice plants. The research was aimed to know the most resistant varieties to bacterial (Xanthomonas oryzae pv. oryzae) in seedling phase. The research was conducted May up to Juli 2012 at Green House Livestock, Agriculture and Horticulture UPTD Serang city. The research used a Randomized Completely Blok Design (RCBD) with one factor, each one tray planted 3 varieties. Test varieties were planted in the middle, on the right was susceptible variety (IR-64) and to the left of the comparison resistant variety (Conde). Each variety was planted 10 seeds, so there were 30 rice stalks. There were 10 trays experiment, with 3 replications. Overall there were 30 trays trial. Results of research showed that from 10 varieties had tested, levels of resistance to bacterial leaf blight disease (BLB) in seedling phase were: (1) Waler 17,56 %, (2) Tambleg 18,46 %, (3) Kewal Bulu Hideng 20, 43 %, (4) Gadog 20,84 %, (5) Jaketra 21,58 %, (6) Kewal Cere 23,65 %, (7) Ketan Laleur 25,80 %, (8) Jalawara Hawara 26,29 %, (9) Ketan Solo 29,20 %, (10) Kewal Gudril 29,93 %. The fastest BLB incubation period was local variety of Kewal Gudril within 4-5 days.Key words : Local Varieties of Banten, Bacterial Leaf Blight, Xanthomonas oryzae pv. oryzae, Resistance and Disease Intensity.

ABSTRACTThe objective of the research was to obtain information on inheritance of characters related seed soybean storability. Genetic material used were 10 varieties and 10 breeding lines. The research was arranged in randomized completely block design with three replicates. The results showed that all characters observed was significantly affected by genotypes. Electrical conductivity showed the highest heritability among the characters observed. Some genotypes (B.3749, B.3641, Tanggamus, and Burangrang) showed good storability after 2 month stored period under room temperature conditions.Key words: soybean, seed storability, heritability

ABSTRACTThis research aimed at knowing the potentials of composed siam weed (Chromolaena odorata) for enhancement of crops performance and its effect to fruitflies population’s to chili crops. The research was carried out at the experimental plantation of Agriculture Faculty, Gadjah Mada University, Banguntapan, Bantul, Yogyakarta from Oktober 2009 up to Maret 2010.This research used Randomize Complete Block Design used with 4 treatments, i.e., composed siam weed 40 ha-1 (G), dunk manure of cow 40 ha-1 (S), NPK (N) (Urea N 46% 40 kg/1000 m2, SP 36 20 kg/1000 m2, and KCL 20 kg/1000 m2), and without fertilizer as control (K) were 4 treatmens to repeated 6 time. Observation of arthropods population was taken with interval of 1 week. Crops samples observed were consisted of 2 plants per treatment. Crops performances observed were fruit number, fresh weight and dry weight of fruit, fresh weight and dry weight of crops. Totals N-leaf was analyzed on generative phases of the crops.Composed siam weed can not increased damage of herbivores if compared with other treatment, it’s indicated that highest of weigh of fruits and weight of crops. The result of research indicated that composed siam weed if compared with NPK and dunk manureof cow, that composed siam weed can not increased frutflies population. It suggest fruitflies prefer nutrition on fruit to secondary compound in chili crop.Key words: fruitflies, population, siam weed, chili.
