| Abstrak (Bhs. Indonesia) | Penelitian ini bertujuan untuk (1) mengetahui pengaruh aplikasi biopestisida berbasis B. subtilis B298 terhadap aspek fisiologis dan hasil tanaman cabai merah. (2) mengetahui pengaruh aplikasi biopestisida berbasis B. subtilis B298 terhadap kandungan fenol total pada tanaman cabai merah. (3) mengetahui kombinasi aplikasi biopestisida B. subtilis B298 dengan fungisida terhadap respon fisiologis tanaman cabai merah. Penelitian dilaksanakan di lahan desa Karangturi, Kecamatan Mrebet, Kabupaten Purbalingga, pada bulan Maret sampai Agustus 2017. Rancangan percobaan yang digunakan adalah Rancangan Acak Kelompok (RAK) dengan pola nonfaktorial, terdiri atas 4 perlakuan dan 6 ulangan sehingga terdapat 24 unit percobaan. Perlakuan yang dicoba yaitu kontrol, Biopestisida berbasis B. subtilis B298, fungisida berbahan aktif propineb, kombinasi B. subtilis B298 dengan fungisida. Variabel yang diamati berupa kadar klorofil, jumlah dan bukaan stomata, luas daun per tanaman, bobot tanaman segar, bobot tanaman kering, laju pertumbuhan, jumlah bunga per tanaman, jumlah buah per tanaman, dan bobot buah. Hasil penelitian menunjukkan bahwaakombinasi B. subtilis B298 dengan fungisida dapat meningkatkan bobot kering tanaman hingga 27,87% dan laju pertumbuhan tanaman hingga 29,03%. Aplikasi B. subtilis B298 dapat meningkatkan jumlah buah per tanaman hingga 9,24%. Aplikasi B. subtilis B298 belum mampu meningkatkan kadar senyawa fenol secara signifikan, namun apabila dikombinasikan dengan fungisida dapat meningkatkan kadar fenol hingga 17,94%. |

| Abtrak (Bhs. Inggris) | This study aims to (1) study the effect of biopesticide applications based on B. subtilis B298 on physiological aspects of red pepper plant. (2) study the effect of biopesticide application based on B. subtilis B298 on total phenol content in red pepper plant. (3) study the combination of biopesticide application of B. subtilis with fungicide on physiological response of red pepper plant. The research was conducted in Karangturi village land, Mrebet district, Purbalingga District. This research was conducted from March to August 2017. The study used Randomized Block Design (RAK) with nonfactorial pattern, consisting of 4 treatments and 6 replications so that there were 24 experimental units. Treatment are control, B. subtillis B298, fungicide with active material Probpineb, and combination B. subtillis B298, fungicide active material Probpineb. Variables observed included chlorophyll content, number and stomatal opening, leaf area per plant, fresh plant weight, dry weight of plant, growth rate, number of flowers per plant, number of fruit per plant, and fruit weight. The results showed that Combination application of B. subtilis B298 with fungicide can increase plant dry weight up to 27,87% and plant growth rate up to 29,03%.Root dry weight was the parameter of plant growth rate, with the highest applications B. subtilis B298 can increase the number of fruits per plant up to 9.24%. Application B. subtilis B298 has not been able to increase phenol content significantly, but with fungicide can increase phenol level until 17,94%. |
