Abstract

Astuti et al, 2018. Utilization of Organic Waste in the Making of Bacillus thuringiensis-based Bioinsecticides as Agents for Control of Caisim Brassica juncea Pests. JLSO 7(2):136-143. Bacillus thuringiensis was one of the entomopathogenic bacteria that can produces toxic crystal proteine (ᴕ-endotoksin). The use of bioinsecticide as a biological agent in pest control was one component of integrated pest control (IPM). The aimed of this reseacrh was to know the population of pests in plants and the percentage of damage to plants that exist in each treatment. The research was conducted in a vegetable garden in the Banyuasin district in November 2017 until January 2018. The research method used a randomized block design with 5 treatments and 4 blocks. The treatment was Bacillus thuringiensis KJ3R5 cultured in coconut water and rice washing water  (A), Bacillus thuringiensis LC2 cultured in coconut water and tofu wastewater (B), commercial Bacillus thuringiensis (C), inorganic insecticide (sidametrin) (D), and water as control (E). The variables observed were arthropod populations on the canopy and ground surface of choy sum (Brassica rapa var. parachinensis or Brassica chinensis var. parachinensis) plants. The results showed that 4 species of pests i.e. Pyllotreta crucifera, Spodoptera litura, Plutella xylostella, and Helula sp. Treatment with Bacillus thuringiensis LC2 (B) resulted in reduction of plant damage by 61%.

Abstract

Chili (Capsinum annum) is a horticultural plant that is useful as a spice in the kitchen, besides containing vitamins that are good for health. This study aimed as an effort to make jengkol skin agricultural waste useful by adding chicken manure organic fertilizer at different doses with the potential to increase growth and yield of chili plants on acidic dry land. The field experiment was conducted on the land of the Food Crops Agriculture Office, Gandus District, Palembang from March to May 2022. Randomized factorial group experimental design with 2 factors, namely the first factor: the dose of Jengkol Peel Biochar fertilizer (B) consisting of: B1 = 5 tons/ha, B2 =15 tons/ha, B3=25 tons/ha. The second factor: the dose of chicken manure (K) consists of: K0 = 0 (without fertilizer chicken manure), K1 = 10 tons/ha, K2 = 20 tons/ha, K3 = 30 tons/ha. Growth and yield were observed by measuring plant height (cm), stem diameter (cm), number of productive branches (branches), chili weight per plant (g), chili weight per plot (g). The best trial was obtained in the combination treatment dose of 15 tons/ha of jengkol peel biochar fertilizer and 30 tons/ha of chicken manure, which was the best treatment for the growth and production of chilies, with a yield per plot of 343.5 g/plant or equivalent to 10.99 tons/ha.
