Abstract

The main weakness faced by the people of Kiniar Village, East Tondano District, is the lack of knowledge and skills of the community in managing organic waste as a compost base and the use of fermenter technology which can accelerate composting so that it can overcome the amount of organic waste. In order to overcome the weaknesses / problems of the people of Kiniar Village, East Tondano District in making compost from organic waste material and the application of fermenter technology that can help speed up composting, socialization and training were carried out in the Community Partnership Program (PKM) activity, namely making compost from organic waste by utilizing Effective Microorganisms ( EM4). From the pretest value after the measurement, the results showed that the highest understanding of the material was found in the value interval 31-40 with 13 participants (34.21%), while those with the lowest understanding were 7 participants in the 0-10 value interval (18.43%). Based on the results of the post-test analysis, it was found that at the 71-80 value interval, 13 participants received the highest score with a percentage of 34.22% and the lowest was at the 41-50 value interval with 2 participants (5.27%). Seeing the mean value of the percentage of post-test measurements, it can be seen that a significant increase from the pretest score, there are 5 participants who are in the 91-100 value interval (13.15%). The results obtained from the recapitulation of the evaluation of learning topics during the activity showed that there were 18 participants who had a very good understanding of the material which was also marked by very good motivation from the participants.

Abstract

The armyworm frugiperda (Spodoptera frugiperda) is one of the insect pests of the Order Lepidoptera that attacks corn plantations in Tomohon City. One of the efforts to control pests is the use of entomopathogens. This study aims to identify and analyze the pathogenicity of the entomopathogenic fungus Tomohon isolate against larvae S. frugiperda. This research was conducted in-vitro using experimental methods. Data were analyzed using probit analysis and Anova test at 95% level and the smallest significant difference test at 5% confidence level. The results showed that the entomopathogenic fungus that attacked the larvae of S. frugiperda was a species of Metarhizium rileyi. The mortality percentage of the treatment that killed the larvae the fastest until it reached an average mortality of 100%, namely spore density of 109 only took seven days after treatment (DAT). The LT50 value is 4 days, and the LC50 value is a concentration of 5.4. For the results of the analysis of the average mortality percentage of S. frugiperda carried out on four DAT using the ANOVA test, there were differences in the mortality of each treatment.Keywords: Metarhizium rileyi; entomopathogen; Spodoptera frugiperdaAbstrakUlat grayak frugiperda (Spodoptera frugiperda) merupakan salah satu hama serangga dari Ordo Lepidoptera yang menyerang perkebunan jagung di Kota Tomohon. Salah satu upaya untuk mengendalikan hama yaitu dengan pemanfaatan entomopatogen. Penelitian ini bertujuan untuk menganalisis patogenisitas jamur entomopatogen isolat Tomohon terhadap Larva S. frugiperda. Penelitian ini dilakukan secara in-vitro dengan menggunakan metode eksperimental. Data dianalisis menggunakan analisis probit dan uji Anava pada taraf 95% dan uji beda nyata terkecil pada taraf kepercayaan 5%. Hasil penelitian menunjukkan bahwa jamur entomopatogen yang menyerang larva S. frugiperda merupakan spesies Metarhizium rileyi. Persentase mortalitas perlakuan yang paling cepat mematikan larva hingga mencapai rata-rata mortalitas 100% yaitu kerapatan spora 109 konidium/ml hanya membutuhkan waktu tujuh hari setelah perlakuan (HSP). Nilai LT50 yaitu 4 hari, dan nilai LC50 yaitu konsentrasi 105,4 konidium/ml. Untuk hasil analisis rata-rata persentase mortalitas S. frugiperda pada empat HSP dengan menggunakan uji anava menunjukkan adanya perbedaan pada mortalitas tiap perlakuan.Kata Kunci: Metarhizium rileyi; entomopatogen; Spodoptera frugiperda
