    The utilization of entomopathogenic nematodes is an example of the uses of an environmentally friendly biological agent. Entomopathogenic nematodes of the family Steinernematidae and Hetrorhabditidae are very potential to control insect pests. The purpose of this study was to study the pathogenicity of the entomopathogenic nematode Steinernema carpocapsae (all strains) as a biological control against Plutella xylostella. This research includes 2 stages, namely the preparation stage and laboratory experiments. The experimental design in this study was a completely randomized design (CRD) consisting of six treatments and three replications. The treatments tested were entomopathogenic nematode concentrations consisting of six levels: 0, 8, 16, 32, 64 and 128 infective juvenile per ml. The LC50 and LT50 values were calculated using Probit analysis. The results of observations of nematodes that enter the insect body and pest mortality were analyzed using analysis of variance (ANOVA), once showing a significant difference, it was then continued to the DMRT test at 5% level. Based on the results of the study, the highest pathogenicity against Plutella xylostella was Steinernema carpocapsae (all strains) when compared to Steinernema glaseri (NC) and Steinernema sp. local isolates. Resistance to Steinernema carpocapsae (all strains) and the LC50Ā value were determined by the age of Plutella xylostella larvae. The bigger and older the larvae, the more its resistance to Steinernema carpocapsae (All strains) and the LC50 value. The number of entomopathogenic nematodes that enter the body of Plutella xylostella increased with increasing length of contact time.Penggunaan nematoda entomopatogen merupakan salah satu pemanfaatan agensia hayati yang ramah lingkungan. Nematoda entomopatogen dari famili Steinernematidae dan Hetrorhabditidae sangat potensial untuk mengendalikan serangga hama. Tujuan dari penelitian ini adalah mempelajari patogenisitas nematoda entomopatogen Steinernema carpocapsae (all strain) sebagai pengendali hayati terhadap hama Plutella xylostella. Penelitian ini meliputi 2 tahap yaitu tahap persiapan dan percobaan laboratorium. Rancangan percobaan pada penelitian ini adalah Rancangan Acak Lengkap (RAL) yang terdiri enam perlakuan dan tiga ulangan. Perlakuan yang diujikan adalah konsentrasi nematoda entomopatogen yang terdiri enam taraf: 0, 8, 16, 32, 64 dan 128 infektif juvenile/ml. Nilai LC50 dan LT50 dihitung menggunakan analisis probit. Hasil pengamatan nematoda yang masuk dalam tubuh serangga dan mortalitas hama dianalisis menggunakan analisis sidik ragam (ANOVA), apabila menunjukkan beda nyata dilanjutkan uji DMRT taraf 5%. Berdasarkan hasil penelitian, patogenisitas tertinggi terhadap Plutella xylostella adalah Steinernema carpocapsae (all strain) bila dibandingkan dengan Steinernema glaseri (NC) dan Steinernema sp. isolat lokal. Ketahanan terhadap Steinernema carpocapsae (All strain) dan nilai LC50 ditentukan umur larva Plutella xylostella. Semakin besar dan tua umur larva, ketahanan terhadap Steinernema carpocapsae (All strain) dan nilai LC50 juga semakin meningkat. Jumlah nematoda entomopatogen yang masuk kedalam tubuh Plutella xylostella semakin banyak seiring dengan bertambah lamanya waktu kontak

    INTEGRATED DESEASE MANAGEMENT FOR CHILI FARMING IN BREBES AND MAGELANG - CENTRAL JAVA: SOCIAL ECONOMIC IMPACTS

    Get PDF
    This study aims to analyze the impact of an integrated disease management (IDM) on chilli. Chili disease control technologies that include crop barrier with corn and Crotalaria, and compost tea have been introduced to farmers in Magelang and Brebes. A qualitative approach was used to assess and estimate the socio-economic impact of agricultural research. The study was conducted in 2011. The results showed that based on land use chili, the net economic benefits generated was relatively low. There were only a few farmers who have adopted the technology on chili peppers. Furthermore, the survey also illustrates that three years after its introduction in 2007 the technology status at farm level was just at consciousness phase. Learning of this fact, a thorough evaluation of the technology on chili pepper should be done immediately. Research institutions which have developed the technology should encourage bottom-up initiatives and build a shared commitment to complete the implementation of a clear strategic plan. The adoption of the strategic plan should include the integration of research activities with promotional activities for example by revitalizing participatory approaches to awareness of farmers

    Marketing channels of chili: players, levels, and segmentations

    Get PDF
    Chili production is an essential commodity in Indonesia, and the marketing issues frequently disrupt the economy. This paper aims to analyze the distribution channel of chili and formulate a suitable policy to overcome the marketing problems. A market survey was qualitatively conducted at a producer, intermediary, wholesaler, and retailer levels. The results were descriptively presented using tables and figures. The analysis shows that the marketing channel of chili in Indonesia was long and complicated. Many players were starting at the village level to the provincial level. Segmented markets were based on the types of chili, which were categorized as local and hybrid cultivars. Farmers selected the marketing channels because of business circumstance and their farm location. Distance and gentleman agreement with traders limited farmers to select the marketing channel. Thus, the government is strongly recommended to provide a unique vegetable market such as an agribusiness terminal close to the center of production. This action will shorten the marketing chain such that both producers and consumers gain the benefits. The role of the private sector will be crucial in order to keep healthy agribusiness
