Abstract

ABSTRACT Efficacy of Essential Oil of Lemongrass (Cymbopogon citratus L.) to Diamond Back Moth (Plutella xylostella L.) on Cabbage in the Laboratory The use of synthetic pesticides continuously will be affect the biotic and non-biotic factors. Therefore, the others control measure which were practically, effectively and safely to human being and environmental - frendly must be created. Geographic condition of Indonesian has been known is rich in biodiversity is necessary to be studied to find the sources for pest control measure which is environmental-friendly. Study about “ Efficacy of Essential oil of Lemongrass (Cymbopogon citratus L.) to Diamond Back Moth (Plutella xylostella L.) on Cabbage was conducted in February, 4. to October, 18.2012 in the Laboratory of Pest and Diseases, Departement of Agroekotechnology, Faculty of Agriculture, Udayana University. The purpose of this study is to determine killing capacity of essential oil of Lemongrass (C. citratus) against Diamond Back Moth (P. xylostella) on Cabbage. The results showed that the essential oil of Lemongrass is effective to kill the larvae of DBM (P. xylostella). The level of concentrations that is used as treatment in this study are 1.5%, 1.25%, 1.%, 0.75%, and 0.5% that have a significant effect to kill the larvae of P. xylostella compare to the control treatment (tween 80 and water). Concretation 0.5% of lemongrass oil causing mortality in average 38.67%, while the concentrations 1.5% is 100%. The concretations 1.25%, 1%, and 0.75% their percentage of mortality are 94.67%, 74.67%, and 56%, respectively. Base on the results of this study, the optimum concretation which are give mortality to the larvae is 1,5% with the percentage of mortality reach to 100% on 6 days after treatment. Key words: Efficacy, Lemongrass (Cymbopogon citratus), Diamond Back Moth (Plutella xylostella)

Abstract

ABSTRACT Study of Resistance of Some Lines and Varieties of Chili Pepper to Antraknosa Disease in Abang Songan Village, Kintaman District, Bangli Regency Increased production of chili is necessary due to increased demand of chili. Anthracnose is one of the major diseases in chili. The disease is caused by the fungus Colletotrichum spp. The study was conducted in the village of Abang Songan, Kintamani, Bangli from February to May 2012. The materials used in this study were 20 strains of chili seeds. A total of 16 lines from AVRDC chili seeds and 4 varieties of chili seeds locally as the benchmark that consists of 3 varieties of Balitsa and 1 local variety in Bali. The experiment was conducted using Randomized Block Design (RBD), to obtain the average value of the observed variables were divided into 3 replicates where each replication consisting of 20 plots and each plot consisted of 20 plants. The observations made on the productivity of pepper and disease attacks the intensity and incidence of disease. Productivity is highest chili varieties Cape (46.77 tons), while the highest strain AVRDC is AVPP 0513 (23.65 tons). Lowest local varieties are varieties Kencana (21.23 tons), while the lowest is the strain AVRDC AVPP strain 0718 (4.26 tons). The intensity and the highest incidence is AVPP strain 1003 with 16.67% of the intensity of the attacks included into the category vulnerable to disease and anthracnose disease incidence was 23.61%. The use of high-yielding varieties of seeds is one of the important factors in the success of the production, so the assembly of high yielding varieties of peppers needed to improve productivity.

Abstract

ABSTRACT Application Polymerase Chain Reaction (PCR) Technique to Variation Symptoms Disease Citrus Vein Phloem Degeneration (CVPD) on Several Types of Citrus Leaves CVPD disease is one of the major diseases in citrus plant. CVPD disease spread from plant to plant by insect vectors Diaphorina citri, and from one region to another region infected by seed. CVPD disease causes symptoms, the leaves become chlorotic with veins remain green. This study aims to determine the PCR method can detect CVPD of citrus from mild to severe symptoms. CVPD symptoms observed on several types of citrus leaves (Siam, Selayar, Besakih, Tejakula, Sweet, Purut, Lime, Lemo, and pomelo) showed chlorosis symptoms from mild to severe. Then the plants were symptomatic will be identified molecular in the Biotechnology Lab. After electrophoresis on almost all samples showed DNA bands with size 1160 bp. Therefore 1160 bp was had bacteri Liberobakter, the plants reacted positive with Liberobakter asiaticum Keyword: CVPD, Liberobacter asiaticum, PCR

Abstract

ABSTRACT The Influence of Composition Mixed Media Materials Plant and IBA Concentration on Growth of Seedlings Ngumpen Wani Bali (Mangifera caesia Jack) The experiment was conducted at plastic house at the Experimental Farm of the Faculty of Agriculture Udayana University Pegok, from January to May 2012. The objective of research was to determine the best concentration of growing media and plant growth regulators IBA to growth of seedlings wani Ngumpen Bali. The study used a randomized block design (RBD) with two factors. The first factor was growing media compositions comprising three types of media: soil + mixture of sand + organic matter (v: v: v = 3:2:1), soil + mixture of sand + organic matter (v: v: v = 3:1:2) and soil + mixture of sand + organic matter (v: v: v = 2:3:1). The second factor was four level of IBA i.e : 0 ppm, 50 ppm, 100 ppm, and 200 ppm. The results showed that treatment of growing media was not significant effect on plant height, number of leaves, stem segments, flushing cycle, stem diameter, leaf area and leaf NPK content of nutrients. While the concentration of IBA treatment was highly significant for plant height. Interactions between growing media and IBA concentrations was significantly on the nutrient content of N leaves only. The highest plant height was obtained at the 100 ppm IBA concentration (52.13 cm), while the lowest was obtained at control (36.74 cm). Keywords: Growing Media, IBA, Seeds, and Wani Ngumpen Bali

Abstract

ABSTRACT Quality Analysis of MOL (Local Microorganism) Solution Based on Gamal (Gliricidia sepium) Leaves The purpose of this research was to find out the effects of gamal (Gliricidia sepium) leaves concentration and term of fermentation to the quality of MOL (local microorganism) solution. The research was held on September 2012 until November 2012, at Soil Laboratory, Faculty of Agriculture, Udayana University. Randomizing block design with two factors, including gamal leaves concentration (K) and fermentation term (F). The observation parameters of this research were total population of bacteria, total population of fungi, N-total, C-organic, C/N ratio. The analysis of gamal leaves concentration and the fermentation term was highly significant (P<0,01) affect. The total high population of bacteria in the K1 treatment be found the treatment F3 , 4,30 x 108 cfu ml-1, the total high population of bacteria in the K2 treatment can be found in the F3 treatment is 6,37 x 108 cfu ml-1, the total high of population of bacteria in the K3 treatment can be found in the F3 treatment is 8,63 x 108 cfu ml-1, the total population of bacteria in the K4 can be found in the F3 treatment is 9,07 x 108 cfu ml-1. The total population of fungi in the K1 treatment can be found in the F3 is 8,23 x 105 cfu ml-1, the total population of fungi in the K2 treatment can be found in the F3 is 8,27 x 105 cfu ml-1, the total population of fungi in the K3 treatment can be found in the F3 is treatment is 8,67 x 105 cfu ml-1, the total population of fungi in the K4 treatment can be found F3 treatment is 10,20 x 105 cfu ml-1. Concentration of 600 g/l gamal leaves on three weeks of fermentation have the best quality of mol solution. Keywords: Local Microorganisms (MOL), gamal leaves, fermentation term
