Abstract: Edi Kurnia, NIM 168210049 “Efektivitas Aplikasi Beauveria Bassiana Dalam Pengendalian Hama Baru Tanaman Jagung Spodoptera Frugiperda ( J.E. Smith) Di Laboratorium”. Dibawah bimbingan Ibu Ir. Azwana, MP selaku ketua pembimbing dan Dr.Ir. Suswati, MP selaku anggota pembimbing. Penelitian ini dilaksanakan di laboratorium LLDIKTI Wilayah 1 Medan, Kecamatan Percut Sei Tuan, Kabupaten Deli Serdang Provinsi Sumatera Utara, mulai bulan Oktober 2020 hingga Maret 2021. Tujuan penelitian ini yaitu untuk mendapatkan data tentang efektivitas aplikasi Beauveria bassiana dalam mengendalikan hama Spodoptera frugiperda di skala laboratorium. Penelitian ini menggunakan Rancangan Acak Lengkap ( RAL) Faktorial yang terdiri dari 2 faktor perlakuan. Perlakuan factor 1 pemberian Beauveria bassiana yaitu: B0 = Kontrol ( tanpa perlakuan ), B1 = 108 (konidia/ml-1), B2 = 106 (konidia/ml-1), B3 = 104 (konidia/ml-1) dan perlakuan factor 2 stadia larva Spodoptera frugiperda yaitu : S1 = larva instar 3, S2 = larva instar 5, S3 = Stadia pre pupa, S4 = Stadia Pupa.. Parameter yang diamati adalah diameter koloni cendawan Beauveria bassiana, viabilitas spora cendawan Beauveria bassiana, mortalitas Spodoptera frugiperda. Hasil penelitian menunjukkan bahwa : aplikasi Beauveria bassiana berpengaruh sangat nyata terhadap persentase mortalitas Spodoptera frugiperda dan berbagai stadia Spodoptera frugiferda. Tetapi tidak berpengaruh nyata terhadap perlakuan kombinasi antara aplikasi berbagai kerapatan Beuaveria bassiana dan berbagai instar Spodoptera frugiperda terhadap persentase mortalitas Spodoptera frugiperda. B.bassiana dengan kerapatan konsentrasi 108 dapat membunuh S.frugiperda sebesar 50% dengan persentase pupa terbentuk terendah pada perlakuan 104 yaitu sebesar 32,50% sedangkan persentase imago terbentuk sebesar 17,50%. Cendawan B. bassiana dengan kerapatan 108 merupakan perlakuan yang terbaik dalam mengendalikan S. frugiperda di skala lab. Edi Kurnia,NIM 168210049 “Effectivity Beauveria bassina Application In New Pest Control Corn Plants Spodoptera frugiperda (J.E.Smith) In The Laboratory” Under the supervision of Mrs. Ir. Azwana,MP as the chairman of the supervision and Mrs. Dr.Ir.Suswati,MP as the member of the supervisor.This research was conducted at the Laboratory LLDIKTI Wilayah 1 Medan, Percut Sei Tuan, Kabupaten Deli Serdang, North Sumatera Province, From Oktober 2020 to March 2021. The purpose of this study was to obtain data on the effectiveness of the application of B. bassiana in controlling the Spodoptera frugiperda pest in laboratory scale. The design used is the Factorial random Plat of the Complete (RAL) which is consist of two treatment factor,firs is was given Beauveria bassiana, namely: B0= control (without treatment),B1= 104 (conidia/ml-1), B2= 106 (conidia/ml-1), B3= 108 (conidia/ml-1), Second is the larvae stage Spodoptera frugiferda, namely: S1= 3rd instar larvae,S2= 5th instar larvae,S3= pre pupa stage,S4=pupa stage.. The parameter observed in this study :diameter of the Beauveria bassiana mushroom colony,the viability of Beauveria bassiana spores, the mortality of Spodoptera frugiperdas. The results showed that: the application of Beauveria bassiana had a very significant effect on the percentage of mortality of Spodoptera frugiperda and various stages of Spodoptera frugiperda . But there was no significant effect on the combination treatment between the application of various densities of Beauveria bassiana and various instars of Spodoptera frugiperda on the percentage of mortality of Spodoptera frugiperda. B. bassiana with a concentration density of 108 can kill S. frugiperda by 50% and the lowest percentage of pupae formed in treatment 104 is 32.50% while the percentage of imago formed is 17.50%. The fungus B. bassiana with a density of 108 was the best treatment for controlling S. Frugiperda.
