Abstract

ABSTRACT Shallots (Allium ascalonicum L.) is a leading vegetable commodity in Indonesia which is cultivated in an incentive by farmers. The development of shallot farming in Indonesia is directed at increasing yields, quality of production and income as well as improving the standard of living of farmers. Loss of shallot production can not be separated from the effect of increasing or decreasing the attack of plant pests and diseases. This study aims to determine the concentration of the biofungicide active ingredient Streptomyces sp 1 x 106 cfu/gram and Geobacillus sp 1 x 106 cfu/gram The most effective for controlling purple spot disease on shallots . This research was carried out from November 2021 to January 2022 in Wonodoyo Village, Cepogo District, Boyolali Regency at an altitude of 1,300 masl with brown lithosol soil type. The method used in this study was a non-factorial Completely Randomized Block Design (CRBD) with 5 (five) different biofungicide concentrations. The concentration treatment used is 1.5 gr / liter ( E1 ), 1,25 gr / liter ( E2 ), 1,0 gr / liter ( E3 ), 0,75 gr / liter ( E4 ), and farmer treatment ( E0 ). The results showed that the concentration treatment of the biofungicide active ingredient Streptomyces sp 1 x 106 cfu/gram and Geobacillus sp 1 x 106 cfu/gram gives a very real influence on the parameters of attack intensity Alternaria porri , weight of wet stover, weight of dry stover, weight of dry tuber, and number of leaves . However, it had no significant effect on plant height parameters. The level of effectiveness of the biofungicide active ingredient Streptomyces sp 1 x 106 cfu/gram and Geobacillus sp 1 x 106 cfu/gram on attack intensity parameter The best Alternaria porri was treated with a concentration of 1,50 gr /liter ( E1 ), with an efficacy level of 76.19 %. Keywords: shallot , biofungicide, Streptomyces, Geobacillus , Alternaria porri.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh konsentrasi dan interval pemberian fermentasi air cucian beras terhadap pertumbuhan dan hasil tanaman pare (Momordica charantia L.). Penelitian ini menggunakan metode faktorial dengan pola dasar Rancangan Acak Kelompok Lengkap (RAKL) dengan 2 faktor perlakuan dan 3 blok sebagai ulangan. Faktor pertama adalah pemberian konsentrasi fermentasi air cucian beras yang terdiri atas 3 taraf (K1 : 0,10 l/l air, K2 : 0,20 l/l air, K3 : 0,30 l/l air). Faktor kedua yaitu interval pemberian air cucian beras yang terdiri atas 3 macam perlakuan (T1 : interval 3 hari sekali, T2 : interval 6 hari sekali, T3 : interval 9 hari sekali). Hasil penelitian menunjukkan bahwa perlakuan pemberian konsentrasi pupuk fermentasi air cucian beras berpengaruh sangat nyata terhadap berat buah, panjang buah, berat brangkasan basah, berat brangkasan kering dan tidak berpengaruh nyata terhadap jumlah buah dan diameter buah, dengan hasil terbaik pada perlakuan konsentrasi 0,30 l/l air (K3). Perlakuan interval waktu pemupukan berpengaruh nyata terhadap parameter yang sama dengan hasil terbaik pada perlakuan interval 3 hari sekali (T1). Interaksi antara konsentrasi dan interval pemupukan dengan fermentasi air cucian beras berpengaruh nyata hanya terhadap berat brangkasan basah
